+# terser-webpack-plugin
+
+This plugin uses [terser](https://github.com/terser/terser) to minify/minimize your JavaScript.
+
+## Getting Started
+
+Webpack v5 comes with the latest `terser-webpack-plugin` out of the box. If you are using Webpack v5 or above and wish to customize the options, you will still need to install `terser-webpack-plugin`. Using Webpack v4, you have to install `terser-webpack-plugin` v4.
+
+To begin, you'll need to install `terser-webpack-plugin`:
+
+```console
+npm install terser-webpack-plugin --save-dev
+```
+
+or
+
+```console
+yarn add -D terser-webpack-plugin
+```
+
+or
+
+```console
+pnpm add -D terser-webpack-plugin
+```
+
+Then add the plugin to your `webpack` config. For example:
+
+**webpack.config.js**
+
+```js
+const TerserPlugin = require("terser-webpack-plugin");
+
+module.exports = {
+  optimization: {
+    minimize: true,
+    minimizer: [new TerserPlugin()],
+  },
+};
+```
+
+And run `webpack` via your preferred method.
+
+## Note about source maps
+
+**Works only with `source-map`, `inline-source-map`, `hidden-source-map` and `nosources-source-map` values for the [`devtool`](https://webpack.js.org/configuration/devtool/) option.**
+
+Why?
+
+- `eval` wraps modules in `eval("string")` and the minimizer does not handle strings.
+- `cheap` has not column information and minimizer generate only a single line, which leave only a single mapping.
+
+Using supported `devtool` values enable source map generation.
+
+## Options
+
+- **[`test`](#test)**
+- **[`include`](#include)**
+- **[`exclude`](#exclude)**
+- **[`parallel`](#parallel)**
+- **[`minify`](#minify)**
+- **[`terserOptions`](#terseroptions)**
+- **[`extractComments`](#extractcomments)**
+
+### `test`
+
+Type:
+
+```ts
+type test = string | RegExp | Array<string | RegExp>;
+```
+
+Default: `/\.m?js(\?.*)?$/i`
+
+Test to match files against.
+
+**webpack.config.js**
+
+```js
+module.exports = {
+  optimization: {
+    minimize: true,
+    minimizer: [
+      new TerserPlugin({
+        test: /\.js(\?.*)?$/i,
+      }),
+    ],
+  },
+};
+```
+
+### `include`
+
+Type:
+
+```ts
+type include = string | RegExp | Array<string | RegExp>;
+```
+
+Default: `undefined`
+
+Files to include.
+
+**webpack.config.js**
+
+```js
+module.exports = {
+  optimization: {
+    minimize: true,
+    minimizer: [
+      new TerserPlugin({
+        include: /\/includes/,
+      }),
+    ],
+  },
+};
+```
+
+### `exclude`
+
+Type:
+
+```ts
+type exclude = string | RegExp | Array<string | RegExp>;
+```
+
+Default: `undefined`
+
+Files to exclude.
+
+**webpack.config.js**
+
+```js
+module.exports = {
+  optimization: {
+    minimize: true,
+    minimizer: [
+      new TerserPlugin({
+        exclude: /\/excludes/,
+      }),
+    ],
+  },
+};
+```
+
+### `parallel`
+
+Type:
+
+```ts
+type parallel = boolean | number;
+```
+
+Default: `true`
+
+Use multi-process parallel running to improve the build speed.
+Default number of concurrent runs: `os.cpus().length - 1`.
+
+> **Note**
+>
+> Parallelization can speedup your build significantly and is therefore **highly recommended**.
+
+> **Warning**
+>
+> If you use **Circle CI** or any other environment that doesn't provide real available count of CPUs then you need to setup explicitly number of CPUs to avoid `Error: Call retries were exceeded` (see [#143](https://github.com/webpack-contrib/terser-webpack-plugin/issues/143), [#202](https://github.com/webpack-contrib/terser-webpack-plugin/issues/202)).
+
+#### `boolean`
+
+Enable/disable multi-process parallel running.
+
+**webpack.config.js**
+
+```js
+module.exports = {
+  optimization: {
+    minimize: true,
+    minimizer: [
+      new TerserPlugin({
+        parallel: true,
+      }),
+    ],
+  },
+};
+```
+
+#### `number`
+
+Enable multi-process parallel running and set number of concurrent runs.
+
+**webpack.config.js**
+
+```js
+module.exports = {
+  optimization: {
+    minimize: true,
+    minimizer: [
+      new TerserPlugin({
+        parallel: 4,
+      }),
+    ],
+  },
+};
+```
+
+### `minify`
+
+Type:
+
+```ts
+type minify = (
+  input: {
+    [file: string]: string;
+  },
+  sourceMap: import("@jridgewell/trace-mapping").SourceMapInput | undefined,
+  minifyOptions: {
+    module?: boolean | undefined;
+    ecma?: import("terser").ECMA | undefined;
+  },
+  extractComments:
+    | boolean
+    | "all"
+    | "some"
+    | RegExp
+    | ((
+        astNode: any,
+        comment: {
+          value: string;
+          type: "comment1" | "comment2" | "comment3" | "comment4";
+          pos: number;
+          line: number;
+          col: number;
+        }
+      ) => boolean)
+    | {
+        condition?:
+          | boolean
+          | "all"
+          | "some"
+          | RegExp
+          | ((
+              astNode: any,
+              comment: {
+                value: string;
+                type: "comment1" | "comment2" | "comment3" | "comment4";
+                pos: number;
+                line: number;
+                col: number;
+              }
+            ) => boolean)
+          | undefined;
+        filename?: string | ((fileData: any) => string) | undefined;
+        banner?:
+          | string
+          | boolean
+          | ((commentsFile: string) => string)
+          | undefined;
+      }
+    | undefined
+) => Promise<{
+  code: string;
+  map?: import("@jridgewell/trace-mapping").SourceMapInput | undefined;
+  errors?: (string | Error)[] | undefined;
+  warnings?: (string | Error)[] | undefined;
+  extractedComments?: string[] | undefined;
+}>;
+```
+
+Default: `TerserPlugin.terserMinify`
+
+Allows you to override default minify function.
+By default plugin uses [terser](https://github.com/terser/terser) package.
+Useful for using and testing unpublished versions or forks.
+
+> **Warning**
+>
+> **Always use `require` inside `minify` function when `parallel` option enabled**.
+
+**webpack.config.js**
+
+```js
+// Can be async
+const minify = (input, sourceMap, minimizerOptions, extractsComments) => {
+  // The `minimizerOptions` option contains option from the `terserOptions` option
+  // You can use `minimizerOptions.myCustomOption`
+
+  // Custom logic for extract comments
+  const { map, code } = require("uglify-module") // Or require('./path/to/uglify-module')
+    .minify(input, {
+      /* Your options for minification */
+    });
+
+  return { map, code, warnings: [], errors: [], extractedComments: [] };
+};
+
+// Used to regenerate `fullhash`/`chunkhash` between different implementation
+// Example: you fix a bug in custom minimizer/custom function, but unfortunately webpack doesn't know about it, so you will get the same fullhash/chunkhash
+// to avoid this you can provide version of your custom minimizer
+// You don't need if you use only `contenthash`
+minify.getMinimizerVersion = () => {
+  let packageJson;
+
+  try {
+    // eslint-disable-next-line global-require, import/no-extraneous-dependencies
+    packageJson = require("uglify-module/package.json");
+  } catch (error) {
+    // Ignore
+  }
+
+  return packageJson && packageJson.version;
+};
+
+module.exports = {
+  optimization: {
+    minimize: true,
+    minimizer: [
+      new TerserPlugin({
+        terserOptions: {
+          myCustomOption: true,
+        },
+        minify,
+      }),
+    ],
+  },
+};
+```
+
+### `terserOptions`

+          ecma: undefined,
+          parse: {},
+          compress: {},
+          mangle: true, // Note `mangle.properties` is `false` by default.
+          module: false,

+
+### `extractComments`
+
+Type:
+
+```ts
+type extractComments =
+  | boolean
+  | string
+  | RegExp
+  | ((
+      astNode: any,
+      comment: {

+    };
+```
+
+Default: `true`
+
+Whether comments shall be extracted to a separate file, (see [details](https://github.com/webpack/webpack/commit/71933e979e51c533b432658d5e37917f9e71595a)).
+By default extract only comments using `/^\**!|@preserve|@license|@cc_on/i` regexp condition and remove remaining comments.
+If the original file is named `foo.js`, then the comments will be stored to `foo.js.LICENSE.txt`.
+The `terserOptions.format.comments` option specifies whether the comment will be preserved, i.e. it is possible to preserve some comments (e.g. annotations) while extracting others or even preserving comments that have been extracted.
+
+#### `boolean`
+
+Enable/disable extracting comments.
+
+**webpack.config.js**
+
+```js

+      new TerserPlugin({
+        extractComments: true,
+      }),
+    ],
+  },
+};
+```
+
+#### `string`
+
+Extract `all` or `some` (use `/^\**!|@preserve|@license|@cc_on/i` RegExp) comments.

+      new TerserPlugin({
+        extractComments: "all",
+      }),
+    ],
+  },
+};
+```
+
+#### `RegExp`
+
+All comments that match the given expression will be extracted to the separate file.
+
+**webpack.config.js**
+
+```js

+        extractComments: /@extract/i,
+      }),
+    ],
+  },
+};
+```
+
+#### `function`
+
+All comments that match the given expression will be extracted to the separate file.
+
+**webpack.config.js**
+
+```js
+module.exports = {
+  optimization: {
+    minimize: true,
+    minimizer: [
+      new TerserPlugin({

+
+          return false;
+        },
+      }),
+    ],
+  },
+};
+```
+
+#### `object`
+
+Allow to customize condition for extract comments, specify extracted file name and banner.
+
+**webpack.config.js**
+
+```js
+module.exports = {
+  optimization: {
+    minimize: true,
+    minimizer: [
+      new TerserPlugin({
+        extractComments: {
+          condition: /^\**!|@preserve|@license|@cc_on/i,
+          filename: (fileData) => {
+            // The "fileData" argument contains object with "filename", "basename", "query" and "hash"
+            return `${fileData.filename}.LICENSE.txt${fileData.query}`;
+          },
+          banner: (licenseFile) => {
+            return `License information can be found in ${licenseFile}`;
+          },
+        },
+      }),
+    ],
+  },
+};
+```
+
+##### `condition`
+
+Type:
+
+```ts
+type condition =
+  | boolean
+  | "all"
+  | "some"
+  | RegExp
+  | ((
+      astNode: any,
+      comment: {
+        value: string;
+        type: "comment1" | "comment2" | "comment3" | "comment4";
+        pos: number;
+        line: number;
+        col: number;
+      }
+    ) => boolean)
+  | undefined;
+```
+
+Condition what comments you need extract.
+
+**webpack.config.js**
+
+```js
+module.exports = {
+  optimization: {
+    minimize: true,
+    minimizer: [
+      new TerserPlugin({
+        extractComments: {
+          condition: "some",
+          filename: (fileData) => {
+            // The "fileData" argument contains object with "filename", "basename", "query" and "hash"
+            return `${fileData.filename}.LICENSE.txt${fileData.query}`;
+          },
+          banner: (licenseFile) => {
+            return `License information can be found in ${licenseFile}`;
+          },
+        },
+      }),
+    ],
+  },
+};
+```
+
+##### `filename`
+
+Type:
+
+```ts
+type filename = string | ((fileData: any) => string) | undefined;
+```
+
+Default: `[file].LICENSE.txt[query]`
+
+Available placeholders: `[file]`, `[query]` and `[filebase]` (`[base]` for webpack 5).
+
+The file where the extracted comments will be stored.
+Default is to append the suffix `.LICENSE.txt` to the original filename.
+
+> **Warning**
+>
+> We highly recommend using the `txt` extension. Using `js`/`cjs`/`mjs` extensions may conflict with existing assets which leads to broken code.
+
+**webpack.config.js**
+
+```js
+module.exports = {
+  optimization: {
+    minimize: true,
+    minimizer: [
+      new TerserPlugin({
+        extractComments: {
+          condition: /^\**!|@preserve|@license|@cc_on/i,
+          filename: "extracted-comments.js",
+          banner: (licenseFile) => {
+            return `License information can be found in ${licenseFile}`;
+          },
+        },
+      }),
+    ],
+  },
+};
+```
+
+##### `banner`
+
+Type:
+
+```ts
+type banner = string | boolean | ((commentsFile: string) => string) | undefined;
+```
+
+Default: `/*! For license information please see ${commentsFile} */`
+
+The banner text that points to the extracted file and will be added on top of the original file.
+Can be `false` (no banner), a `String`, or a `Function<(string) -> String>` that will be called with the filename where extracted comments have been stored.
+Will be wrapped into comment.
+
+**webpack.config.js**
+
+```js
+module.exports = {
+  optimization: {
+    minimize: true,
+    minimizer: [
+      new TerserPlugin({
+        extractComments: {
+          condition: true,
+          filename: (fileData) => {
+            // The "fileData" argument contains object with "filename", "basename", "query" and "hash"
+            return `${fileData.filename}.LICENSE.txt${fileData.query}`;
+          },
+          banner: (commentsFile) => {
+            return `My custom banner about license information ${commentsFile}`;
+          },
+        },
+      }),
+    ],
+  },
+};
+```
+
+## Examples
+
+### Preserve Comments
+
+Extract all legal comments (i.e. `/^\**!|@preserve|@license|@cc_on/i`) and preserve `/@license/i` comments.
+
+**webpack.config.js**
+
+```js
+module.exports = {
+  optimization: {
+    minimize: true,
+    minimizer: [
+      new TerserPlugin({
+        terserOptions: {
+          format: {
+            comments: /@license/i,
+          },
+        },
+        extractComments: true,
+      }),
+    ],
+  },
+};
+```
+
+### Remove Comments
+
+If you avoid building with comments, use this config:
+
+**webpack.config.js**
+
+```js
+module.exports = {
+  optimization: {
+    minimize: true,
+    minimizer: [
+      new TerserPlugin({
+        terserOptions: {
+          format: {
+            comments: false,
+          },
+        },
+        extractComments: false,
+      }),
+    ],
+  },
+};
+```
+
+### [`uglify-js`](https://github.com/mishoo/UglifyJS)

+
+### [`swc`](https://github.com/swc-project/swc)
+
+[`swc`](https://github.com/swc-project/swc) is a super-fast compiler written in rust; producing widely-supported javascript from modern standards and typescript.
+
+> **Warning**
+>
+> the `extractComments` option is not supported and all comments will be removed by default, it will be fixed in future
+
+**webpack.config.js**
+
+```js
+module.exports = {
+  optimization: {
+    minimize: true,
+    minimizer: [
+      new TerserPlugin({
+        minify: TerserPlugin.swcMinify,
+        // `terserOptions` options will be passed to `swc` (`@swc/core`)
+        // Link to options - https://swc.rs/docs/config-js-minify
+        terserOptions: {},
+      }),
+    ],
+  },
+};
+```
+
+### [`esbuild`](https://github.com/evanw/esbuild)
+
+[`esbuild`](https://github.com/evanw/esbuild) is an extremely fast JavaScript bundler and minifier.
+
+> **Warning**
+>
+> the `extractComments` option is not supported and all legal comments (i.e. copyright, licenses and etc) will be preserved
+
+**webpack.config.js**
+
+```js
+module.exports = {
+  optimization: {
+    minimize: true,
+    minimizer: [
+      new TerserPlugin({
+        minify: TerserPlugin.esbuildMinify,
+        // `terserOptions` options will be passed to `esbuild`
+        // Link to options - https://esbuild.github.io/api/#minify
+        // Note: the `minify` options is true by default (and override other `minify*` options), so if you want to disable the `minifyIdentifiers` option (or other `minify*` options) please use:
+        // terserOptions: {
+        //   minify: false,
+        //   minifyWhitespace: true,
+        //   minifyIdentifiers: false,
+        //   minifySyntax: true,
+        // },
+        terserOptions: {},
+      }),
+    ],
+  },
+};
+```
+
+### Custom Minify Function
+
+Override default minify function - use `uglify-js` for minification.
+
+**webpack.config.js**
+
+```js
+module.exports = {
+  optimization: {
+    minimize: true,
+    minimizer: [
+      new TerserPlugin({
+        minify: (file, sourceMap) => {
+          // https://github.com/mishoo/UglifyJS2#minify-options
+          const uglifyJsOptions = {
+            /* your `uglify-js` package options */
+          };
+
+          if (sourceMap) {
+            uglifyJsOptions.sourceMap = {
+              content: sourceMap,
+            };
+          }
+
+          return require("uglify-js").minify(file, uglifyJsOptions);
+        },
+      }),
+    ],
+  },
+};
+```
+
+### Typescript
+
+With default terser minify function:
+
+```ts
+module.exports = {
+  optimization: {
+    minimize: true,
+    minimizer: [
+      new TerserPlugin({
+        terserOptions: {
+          compress: true,
+        },
+      }),
+    ],
+  },
+};
+```
+
+With built-in minify functions:
+
+```ts
+import type { JsMinifyOptions as SwcOptions } from "@swc/core";
+import type { MinifyOptions as UglifyJSOptions } from "uglify-js";
+import type { TransformOptions as EsbuildOptions } from "esbuild";
+import type { MinifyOptions as TerserOptions } from "terser";
+
+module.exports = {
+  optimization: {
+    minimize: true,
+    minimizer: [
+      new TerserPlugin<SwcOptions>({
+        minify: TerserPlugin.swcMinify,
+        terserOptions: {
+          // `swc` options
+        },
+      }),
+      new TerserPlugin<UglifyJSOptions>({
+        minify: TerserPlugin.uglifyJsMinify,
+        terserOptions: {
+          // `uglif-js` options
+        },
+      }),
+      new TerserPlugin<EsbuildOptions>({
+        minify: TerserPlugin.esbuildMinify,
+        terserOptions: {
+          // `esbuild` options
+        },
+      }),
+
+      // Alternative usage:
+      new TerserPlugin<TerserOptions>({
+        minify: TerserPlugin.terserMinify,
+        terserOptions: {
+          // `terser` options
+        },
+      }),
+    ],
+  },
+};

+## Install
+
+```
+npm install ajv-keywords
+```
+
+
+## Usage
+
+To add all available keywords:
+
+```javascript
+var Ajv = require('ajv');
+var ajv = new Ajv;
+require('ajv-keywords')(ajv);
+
+ajv.validate({ instanceof: 'RegExp' }, /.*/); // true
+ajv.validate({ instanceof: 'RegExp' }, '.*'); // false
+```
+
+To add a single keyword:
+
+```javascript
+require('ajv-keywords')(ajv, 'instanceof');
+```
+
+To add multiple keywords:
+
+```javascript
+require('ajv-keywords')(ajv, ['typeof', 'instanceof']);
+```
+
+To add a single keyword in browser (to avoid adding unused code):
+
+```javascript
+require('ajv-keywords/keywords/instanceof')(ajv);
+```
+
+
+## Keywords
+
+### Types
+
+#### `typeof`
+
+Based on JavaScript `typeof` operation.
+
+The value of the keyword should be a string (`"undefined"`, `"string"`, `"number"`, `"object"`, `"function"`, `"boolean"` or `"symbol"`) or array of strings.
+
+To pass validation the result of `typeof` operation on the value should be equal to the string (or one of the strings in the array).
+
+```
+ajv.validate({ typeof: 'undefined' }, undefined); // true
+ajv.validate({ typeof: 'undefined' }, null); // false
+ajv.validate({ typeof: ['undefined', 'object'] }, null); // true
+```
+
+
+#### `instanceof`
+
+Based on JavaScript `instanceof` operation.
+
+The value of the keyword should be a string (`"Object"`, `"Array"`, `"Function"`, `"Number"`, `"String"`, `"Date"`, `"RegExp"`, `"Promise"` or `"Buffer"`) or array of strings.
+
+To pass validation the result of `data instanceof ...` operation on the value should be true:
+
+```
+ajv.validate({ instanceof: 'Array' }, []); // true
+ajv.validate({ instanceof: 'Array' }, {}); // false
+ajv.validate({ instanceof: ['Array', 'Function'] }, function(){}); // true
+```
+
+You can add your own constructor function to be recognised by this keyword:
+
+```javascript
+function MyClass() {}
+var instanceofDefinition = require('ajv-keywords').get('instanceof').definition;
+// or require('ajv-keywords/keywords/instanceof').definition;
+instanceofDefinition.CONSTRUCTORS.MyClass = MyClass;
+
+ajv.validate({ instanceof: 'MyClass' }, new MyClass); // true
+```
+
+
+### Keywords for numbers
+
+#### `range` and `exclusiveRange`
+
+Syntax sugar for the combination of minimum and maximum keywords, also fails schema compilation if there are no numbers in the range.
+
+The value of this keyword must be the array consisting of two numbers, the second must be greater or equal than the first one.
+
+If the validated value is not a number the validation passes, otherwise to pass validation the value should be greater (or equal) than the first number and smaller (or equal) than the second number in the array. If `exclusiveRange` keyword is present in the same schema and its value is true, the validated value must not be equal to the range boundaries.
+
+```javascript
+var schema = { range: [1, 3] };
+ajv.validate(schema, 1); // true
+ajv.validate(schema, 2); // true
+ajv.validate(schema, 3); // true
+ajv.validate(schema, 0.99); // false
+ajv.validate(schema, 3.01); // false
+
+var schema = { range: [1, 3], exclusiveRange: true };
+ajv.validate(schema, 1.01); // true
+ajv.validate(schema, 2); // true
+ajv.validate(schema, 2.99); // true
+ajv.validate(schema, 1); // false
+ajv.validate(schema, 3); // false
+```
+
+
+### Keywords for strings
+
+#### `regexp`
+
+This keyword allows to use regular expressions with flags in schemas (the standard `pattern` keyword does not support flags).
+
+This keyword applies only to strings. If the data is not a string, the validation succeeds.
+
+The value of this keyword can be either a string (the result of `regexp.toString()`) or an object with the properties `pattern` and `flags` (the same strings that should be passed to RegExp constructor).
+
+```javascript
+var schema = {
+  type: 'object',
+  properties: {
+    foo: { regexp: '/foo/i' },
+    bar: { regexp: { pattern: 'bar', flags: 'i' } }
+  }
+};
+
+var validData = {
+  foo: 'Food',
+  bar: 'Barmen'
+};
+
+var invalidData = {
+  foo: 'fog',
+  bar: 'bad'
+};
+```
+
+
+#### `formatMaximum` / `formatMinimum` and `formatExclusiveMaximum` / `formatExclusiveMinimum`
+
+These keywords allow to define minimum/maximum constraints when the format keyword defines ordering.
+
+These keywords apply only to strings. If the data is not a string, the validation succeeds.
+
+The value of keyword `formatMaximum` (`formatMinimum`) should be a string. This value is the maximum (minimum) allowed value for the data to be valid as determined by `format` keyword. If `format` is not present schema compilation will throw exception.
+
+When this keyword is added, it defines comparison rules for formats `"date"`, `"time"` and `"date-time"`. Custom formats also can have comparison rules. See [addFormat](https://github.com/epoberezkin/ajv#api-addformat) method.
+
+The value of keyword `formatExclusiveMaximum` (`formatExclusiveMinimum`) should be a boolean value. These keyword cannot be used without `formatMaximum` (`formatMinimum`). If this keyword value is equal to `true`, the data to be valid should not be equal to the value in `formatMaximum` (`formatMinimum`) keyword.
+
+```javascript
+require('ajv-keywords')(ajv, ['formatMinimum', 'formatMaximum']);
+
+var schema = {
+  format: 'date',
+  formatMinimum: '2016-02-06',
+  formatMaximum: '2016-12-27',
+  formatExclusiveMaximum: true
+}
+
+var validDataList = ['2016-02-06', '2016-12-26', 1];
+
+var invalidDataList = ['2016-02-05', '2016-12-27', 'abc'];
+```
+
+
+#### `transform`
+
+This keyword allows a string to be modified before validation. 
+
+These keywords apply only to strings. If the data is not a string, the transform is skipped.
+
+There are limitation due to how ajv is written:
+- a stand alone string cannot be transformed. ie `data = 'a'; ajv.validate(schema, data);`
+- currently cannot work with `ajv-pack`
+
+**Supported options:**
+- `trim`: remove whitespace from start and end
+- `trimLeft`: remove whitespace from start
+- `trimRight`: remove whitespace from end
+- `toLowerCase`: case string to all lower case
+- `toUpperCase`: case string to all upper case
+- `toEnumCase`: case string to match case in schema
+
+Options are applied in the order they are listed.
+
+Note: `toEnumCase` requires that all allowed values are unique when case insensitive.
+
+**Example: multiple options**
+```javascript
+require('ajv-keywords')(ajv, ['transform']);
+
+var schema = {
+  type: 'array',
+  items: {
+    type:'string',
+    transform:['trim','toLowerCase']
+  }
+};
+
+var data = ['  MixCase  '];
+ajv.validate(schema, data);
+console.log(data); // ['mixcase']
+
+```
+
+**Example: `enumcase`**
+```javascript
+require('ajv-keywords')(ajv, ['transform']);
+
+var schema = {
+  type: 'array',
+  items: {
+    type:'string',
+    transform:['trim','toEnumCase'],
+    enum:['pH']
+  }
+};
+
+var data = ['ph',' Ph','PH','pH '];
+ajv.validate(schema, data);
+console.log(data); // ['pH','pH','pH','pH']
+```
+
+
+### Keywords for arrays
+
+#### `uniqueItemProperties`
+
+The keyword allows to check that some properties in array items are unique.
+
+This keyword applies only to arrays. If the data is not an array, the validation succeeds.
+
+The value of this keyword must be an array of strings - property names that should have unique values across all items.
+
+```javascript
+var schema = { uniqueItemProperties: [ "id", "name" ] };
+
+var validData = [
+  { id: 1 },
+  { id: 2 },
+  { id: 3 }
+];
+
+var invalidData1 = [
+  { id: 1 },
+  { id: 1 }, // duplicate "id"
+  { id: 3 }
+];
+
+var invalidData2 = [
+  { id: 1, name: "taco" },
+  { id: 2, name: "taco" }, // duplicate "name"
+  { id: 3, name: "salsa" }
+];
+```
+
+This keyword is contributed by [@blainesch](https://github.com/blainesch).
+
+
+### Keywords for objects
+
+#### `allRequired`
+
+This keyword allows to require the presence of all properties used in `properties` keyword in the same schema object.
+
+This keyword applies only to objects. If the data is not an object, the validation succeeds.
+
+The value of this keyword must be boolean.
+
+If the value of the keyword is `false`, the validation succeeds.
+
+If the value of the keyword is `true`, the validation succeeds if the data contains all properties defined in `properties` keyword (in the same schema object).
+
+If the `properties` keyword is not present in the same schema object, schema compilation will throw exception.
+
+```javascript
+var schema = {
+  properties: {
+    foo: {type: 'number'},
+    bar: {type: 'number'}
+  }
+  allRequired: true
+};
+
+var validData = { foo: 1, bar: 2 };
+var alsoValidData = { foo: 1, bar: 2, baz: 3 };
+
+var invalidDataList = [ {}, { foo: 1 }, { bar: 2 } ];
+```
+
+
+#### `anyRequired`
+
+This keyword allows to require the presence of any (at least one) property from the list.
+
+This keyword applies only to objects. If the data is not an object, the validation succeeds.
+
+The value of this keyword must be an array of strings, each string being a property name. For data object to be valid at least one of the properties in this array should be present in the object.
+
+```javascript
+var schema = {
+  anyRequired: ['foo', 'bar']
+};
+
+var validData = { foo: 1 };
+var alsoValidData = { foo: 1, bar: 2 };
+
+var invalidDataList = [ {}, { baz: 3 } ];
+```
+
+
+#### `oneRequired`
+
+This keyword allows to require the presence of only one property from the list.
+
+This keyword applies only to objects. If the data is not an object, the validation succeeds.
+
+The value of this keyword must be an array of strings, each string being a property name. For data object to be valid exactly one of the properties in this array should be present in the object.
+
+```javascript
+var schema = {
+  oneRequired: ['foo', 'bar']
+};
+
+var validData = { foo: 1 };
+var alsoValidData = { bar: 2, baz: 3 };
+
+var invalidDataList = [ {}, { baz: 3 }, { foo: 1, bar: 2 } ];
+```
+
+
+#### `patternRequired`
+
+This keyword allows to require the presence of properties that match some pattern(s).
+
+This keyword applies only to objects. If the data is not an object, the validation succeeds.
+
+The value of this keyword should be an array of strings, each string being a regular expression. For data object to be valid each regular expression in this array should match at least one property name in the data object.
+
+If the array contains multiple regular expressions, more than one expression can match the same property name.
+
+```javascript
+var schema = { patternRequired: [ 'f.*o', 'b.*r' ] };
+
+var validData = { foo: 1, bar: 2 };
+var alsoValidData = { foobar: 3 };
+
+var invalidDataList = [ {}, { foo: 1 }, { bar: 2 } ];
+```
+
+
+#### `prohibited`
+
+This keyword allows to prohibit that any of the properties in the list is present in the object.
+
+This keyword applies only to objects. If the data is not an object, the validation succeeds.
+
+The value of this keyword should be an array of strings, each string being a property name. For data object to be valid none of the properties in this array should be present in the object.
+
+```
+var schema = { prohibited: ['foo', 'bar']};
+
+var validData = { baz: 1 };
+var alsoValidData = {};
+
+var invalidDataList = [
+  { foo: 1 },
+  { bar: 2 },
+  { foo: 1, bar: 2}
+];
+```
+
+__Please note__: `{prohibited: ['foo', 'bar']}` is equivalent to `{not: {anyRequired: ['foo', 'bar']}}` (i.e. it has the same validation result for any data).
+
+
+#### `deepProperties`
+
+This keyword allows to validate deep properties (identified by JSON pointers).
+
+This keyword applies only to objects. If the data is not an object, the validation succeeds.
+
+The value should be an object, where keys are JSON pointers to the data, starting from the current position in data, and the values are JSON schemas. For data object to be valid the value of each JSON pointer should be valid according to the corresponding schema.
+
+```javascript
+var schema = {
+  type: 'object',
+  deepProperties: {
+    "/users/1/role": { "enum": ["admin"] }
+  }
+};
+
+var validData = {
+  users: [
+    {},
+    {
+      id: 123,
+      role: 'admin'
+    }
+  ]
+};
+
+var alsoValidData = {
+  users: {
+    "1": {
+      id: 123,
+      role: 'admin'
+    }
+  }
+};
+
+var invalidData = {
+  users: [
+    {},
+    {
+      id: 123,
+      role: 'user'
+    }
+  ]
+};
+
+var alsoInvalidData = {
+  users: {
+    "1": {
+      id: 123,
+      role: 'user'
+    }
+  }
+};
+```
+
+
+#### `deepRequired`
+
+This keyword allows to check that some deep properties (identified by JSON pointers) are available.
+
+This keyword applies only to objects. If the data is not an object, the validation succeeds.
+
+The value should be an array of JSON pointers to the data, starting from the current position in data. For data object to be valid each JSON pointer should be some existing part of the data.
+
+```javascript
+var schema = {
+  type: 'object',
+  deepRequired: ["/users/1/role"]
+};
+
+var validData = {
+  users: [
+    {},
+    {
+      id: 123,
+      role: 'admin'
+    }
+  ]
+};
+
+var invalidData = {
+  users: [
+    {},
+    {
+      id: 123
+    }
+  ]
+};

+See [json-schema-org/json-schema-spec#203](https://github.com/json-schema-org/json-schema-spec/issues/203#issue-197211916) for an example of the equivalent schema without `deepRequired` keyword.
+
+
+### Compound keywords
+
+#### `switch` (deprecated)
+
+__Please note__: this keyword is provided to preserve backward compatibility with previous versions of Ajv. It is strongly recommended to use `if`/`then`/`else` keywords instead, as they have been added to the draft-07 of JSON Schema specification.
+
+This keyword allows to perform advanced conditional validation.
+
+The value of the keyword is the array of if/then clauses. Each clause is the object with the following properties:
+
+- `if` (optional) - the value is JSON-schema
+- `then` (required) - the value is JSON-schema or boolean
+- `continue` (optional) - the value is boolean
+
+The validation process is dynamic; all clauses are executed sequentially in the following way:
+
+1. `if`:
+    1.  `if` property is JSON-schema according to which the data is:
+        1.  valid => go to step 2.
+        2.  invalid => go to the NEXT clause, if this was the last clause the validation of `switch` SUCCEEDS.
+    2.  `if` property is absent => go to step 2.
+2. `then`:
+    1.  `then` property is `true` or it is JSON-schema according to which the data is valid => go to step 3.
+    2.  `then` property is `false` or it is JSON-schema according to which the data is invalid => the validation of `switch` FAILS.
+3. `continue`:
+    1.  `continue` property is `true` => go to the NEXT clause, if this was the last clause the validation of `switch` SUCCEEDS.
+    2.  `continue` property is `false` or absent => validation of `switch` SUCCEEDS.
+
+```javascript
+require('ajv-keywords')(ajv, 'switch');
+
+var schema = {
+  type: 'array',
+  items: {
+    type: 'integer',
+    'switch': [
+      { if: { not: { minimum: 1 } }, then: false },
+      { if: { maximum: 10 }, then: true },
+      { if: { maximum: 100 }, then: { multipleOf: 10 } },
+      { if: { maximum: 1000 }, then: { multipleOf: 100 } },
+      { then: false }
+    ]
+  }
+};
+
+var validItems = [1, 5, 10, 20, 50, 100, 200, 500, 1000];
+
+var invalidItems = [1, 0, 2000, 11, 57, 123, 'foo'];
+```
+
+The above schema is equivalent to (for example):
+
+```javascript
+{
+  type: 'array',
+  items: {
+    type: 'integer',
+    if: { minimum: 1, maximum: 10 },
+    then: true,
+    else: {
+      if: { maximum: 100 },
+      then: { multipleOf: 10 },
+      else: {
+        if: { maximum: 1000 },
+        then: { multipleOf: 100 },
+        else: false
+      }
+    }
+  }
+}
+```
+
+
+#### `select`/`selectCases`/`selectDefault`
+
+These keywords allow to choose the schema to validate the data based on the value of some property in the validated data.
+
+These keywords must be present in the same schema object (`selectDefault` is optional).
+
+The value of `select` keyword should be a [$data reference](https://github.com/epoberezkin/ajv/tree/5.0.2-beta.0#data-reference) that points to any primitive JSON type (string, number, boolean or null) in the data that is validated. You can also use a constant of primitive type as the value of this keyword (e.g., for debugging purposes).
+
+The value of `selectCases` keyword must be an object where each property name is a possible string representation of the value of `select` keyword and each property value is a corresponding schema (from draft-06 it can be boolean) that must be used to validate the data.
+
+The value of `selectDefault` keyword is a schema (from draft-06 it can be boolean) that must be used to validate the data in case `selectCases` has no key equal to the stringified value of `select` keyword.
+
+The validation succeeds in one of the following cases:
+- the validation of data using selected schema succeeds,
+- none of the schemas is selected for validation,
+- the value of select is undefined (no property in the data that the data reference points to).
+
+If `select` value (in data) is not a primitive type the validation fails.
+
+__Please note__: these keywords require Ajv `$data` option to support [$data reference](https://github.com/epoberezkin/ajv/tree/5.0.2-beta.0#data-reference).
+
+
+```javascript
+require('ajv-keywords')(ajv, 'select');
+
+var schema = {
+  type: object,
+  required: ['kind'],
+  properties: {
+    kind: { type: 'string' }
+  },
+  select: { $data: '0/kind' },
+  selectCases: {
+    foo: {
+      required: ['foo'],
+      properties: {
+        kind: {},
+        foo: { type: 'string' }
+      },
+      additionalProperties: false
+    },
+    bar: {
+      required: ['bar'],
+      properties: {
+        kind: {},
+        bar: { type: 'number' }
+      },
+      additionalProperties: false
+    }
+  },
+  selectDefault: {
+    propertyNames: {
+      not: { enum: ['foo', 'bar'] }
+    }
+  }
+};
+
+var validDataList = [
+  { kind: 'foo', foo: 'any' },
+  { kind: 'bar', bar: 1 },
+  { kind: 'anything_else', not_bar_or_foo: 'any value' }
+];
+
+var invalidDataList = [
+  { kind: 'foo' }, // no propery foo
+  { kind: 'bar' }, // no propery bar
+  { kind: 'foo', foo: 'any', another: 'any value' }, // additional property
+  { kind: 'bar', bar: 1, another: 'any value' }, // additional property
+  { kind: 'anything_else', foo: 'any' } // property foo not allowed
+  { kind: 'anything_else', bar: 1 } // property bar not allowed
+];
+```
+
+__Please note__: the current implementation is BETA. It does not allow using relative URIs in $ref keywords in schemas in `selectCases` and `selectDefault` that point outside of these schemas. The workaround is to use absolute URIs (that can point to any (sub-)schema added to Ajv, including those inside the current root schema where `select` is used). See [tests](https://github.com/epoberezkin/ajv-keywords/blob/v2.0.0/spec/tests/select.json#L314).
+
+
+### Keywords for all types
+
+#### `dynamicDefaults`
+
+This keyword allows to assign dynamic defaults to properties, such as timestamps, unique IDs etc.
+
+This keyword only works if `useDefaults` options is used and not inside `anyOf` keywords etc., in the same way as [default keyword treated by Ajv](https://github.com/epoberezkin/ajv#assigning-defaults).
+
+The keyword should be added on the object level. Its value should be an object with each property corresponding to a property name, in the same way as in standard `properties` keyword. The value of each property can be:
+
+- an identifier of default function (a string)
+- an object with properties `func` (an identifier) and `args` (an object with parameters that will be passed to this function during schema compilation - see examples).
+
+The properties used in `dynamicDefaults` should not be added to `required` keyword (or validation will fail), because unlike `default` this keyword is processed after validation.
+
+There are several predefined dynamic default functions:
+
+- `"timestamp"` - current timestamp in milliseconds
+- `"datetime"` - current date and time as string (ISO, valid according to `date-time` format)
+- `"date"` - current date as string (ISO, valid according to `date` format)
+- `"time"` - current time as string (ISO, valid according to `time` format)
+- `"random"` - pseudo-random number in [0, 1) interval
+- `"randomint"` - pseudo-random integer number. If string is used as a property value, the function will randomly return 0 or 1. If object `{ func: 'randomint', args: { max: N } }` is used then the default will be an integer number in [0, N) interval.
+- `"seq"` - sequential integer number starting from 0. If string is used as a property value, the default sequence will be used. If object `{ func: 'seq', args: { name: 'foo'} }` is used then the sequence with name `"foo"` will be used. Sequences are global, even if different ajv instances are used.
+
+```javascript
+var schema = {
+  type: 'object',
+  dynamicDefaults: {
+    ts: 'datetime',
+    r: { func: 'randomint', args: { max: 100 } },
+    id: { func: 'seq', args: { name: 'id' } }
+  },
+  properties: {
+    ts: {
+      type: 'string',
+      format: 'date-time'
+    },
+    r: {
+      type: 'integer',
+      minimum: 0,
+      exclusiveMaximum: 100
+    },
+    id: {
+      type: 'integer',
+      minimum: 0
+    }
+  }
+};
+
+var data = {};
+ajv.validate(data); // true
+data; // { ts: '2016-12-01T22:07:28.829Z', r: 25, id: 0 }
+
+var data1 = {};
+ajv.validate(data1); // true
+data1; // { ts: '2016-12-01T22:07:29.832Z', r: 68, id: 1 }
+
+ajv.validate(data1); // true
+data1; // didn't change, as all properties were defined
+```
+
+When using the `useDefaults` option value `"empty"`, properties and items equal to `null` or `""` (empty string) will be considered missing and assigned defaults.  Use the `allOf` [compound keyword](https://github.com/epoberezkin/ajv/blob/master/KEYWORDS.md#compound-keywords) to execute `dynamicDefaults` before validation.
+
+```javascript
+var schema = {
+  allOf: [
+    {
+      dynamicDefaults: {
+        ts: 'datetime',
+        r: { func: 'randomint', args: { min: 5, max: 100 } },
+        id: { func: 'seq', args: { name: 'id' } }
+      }
+    },
+    {
+      type: 'object',
+      properties: {
+        ts: {
+          type: 'string'
+        },
+        r: {
+          type: 'number',
+          minimum: 5,
+          exclusiveMaximum: 100
+        },
+        id: {
+          type: 'integer',
+          minimum: 0
+        }
+      }
+    }
+  ]
+};
+
+var data = { ts: '', r: null };
+ajv.validate(data); // true
+data; // { ts: '2016-12-01T22:07:28.829Z', r: 25, id: 0 }
+```
+
+You can add your own dynamic default function to be recognised by this keyword:
+
+```javascript
+var uuid = require('uuid');
+
+function uuidV4() { return uuid.v4(); }
+
+var definition = require('ajv-keywords').get('dynamicDefaults').definition;
+// or require('ajv-keywords/keywords/dynamicDefaults').definition;
+definition.DEFAULTS.uuid = uuidV4;
+
+var schema = {
+  dynamicDefaults: { id: 'uuid' },
+  properties: { id: { type: 'string', format: 'uuid' } }
+};
+
+var data = {};
+ajv.validate(schema, data); // true
+data; // { id: 'a1183fbe-697b-4030-9bcc-cfeb282a9150' };
+
+var data1 = {};
+ajv.validate(schema, data1); // true
+data1; // { id: '5b008de7-1669-467a-a5c6-70fa244d7209' }
+```
+
+You also can define dynamic default that accepts parameters, e.g. version of uuid:
+
+```javascript
+var uuid = require('uuid');
+
+function getUuid(args) {
+  var version = 'v' + (arvs && args.v || 4);
+  return function() {
+    return uuid[version]();
+  };
+}
+
+var definition = require('ajv-keywords').get('dynamicDefaults').definition;
+definition.DEFAULTS.uuid = getUuid;
+
+var schema = {
+  dynamicDefaults: {
+    id1: 'uuid', // v4
+    id2: { func: 'uuid', v: 4 }, // v4
+    id3: { func: 'uuid', v: 1 } // v1
+  }
+};
+```

+# json-schema-traverse
+Traverse JSON Schema passing each schema object to callback
+
+[![Build Status](https://travis-ci.org/epoberezkin/json-schema-traverse.svg?branch=master)](https://travis-ci.org/epoberezkin/json-schema-traverse)
+[![npm version](https://badge.fury.io/js/json-schema-traverse.svg)](https://www.npmjs.com/package/json-schema-traverse)
+[![Coverage Status](https://coveralls.io/repos/github/epoberezkin/json-schema-traverse/badge.svg?branch=master)](https://coveralls.io/github/epoberezkin/json-schema-traverse?branch=master)
+
+
+## Install
+
+```
+npm install json-schema-traverse
+```
+
+
+## Usage
+
+```javascript
+const traverse = require('json-schema-traverse');
+const schema = {
+  properties: {
+    foo: {type: 'string'},
+    bar: {type: 'integer'}
+  }
+};
+
+traverse(schema, {cb});
+// cb is called 3 times with:
+// 1. root schema
+// 2. {type: 'string'}
+// 3. {type: 'integer'}
+
+// Or:
+
+traverse(schema, {cb: {pre, post}});
+// pre is called 3 times with:
+// 1. root schema
+// 2. {type: 'string'}
+// 3. {type: 'integer'}
+//
+// post is called 3 times with:
+// 1. {type: 'string'}
+// 2. {type: 'integer'}
+// 3. root schema
+
+```
+
+Callback function `cb` is called for each schema object (not including draft-06 boolean schemas), including the root schema, in pre-order traversal. Schema references ($ref) are not resolved, they are passed as is.  Alternatively, you can pass a `{pre, post}` object as `cb`, and then `pre` will be called before traversing child elements, and `post` will be called after all child elements have been traversed.
+
+Callback is passed these parameters:
+
+- _schema_: the current schema object
+- _JSON pointer_: from the root schema to the current schema object
+- _root schema_: the schema passed to `traverse` object
+- _parent JSON pointer_: from the root schema to the parent schema object (see below)
+- _parent keyword_: the keyword inside which this schema appears (e.g. `properties`, `anyOf`, etc.)
+- _parent schema_: not necessarily parent object/array; in the example above the parent schema for `{type: 'string'}` is the root schema
+- _index/property_: index or property name in the array/object containing multiple schemas; in the example above for `{type: 'string'}` the property name is `'foo'`
+
+
+## Traverse objects in all unknown keywords
+
+```javascript
+const traverse = require('json-schema-traverse');
+const schema = {
+  mySchema: {
+    minimum: 1,
+    maximum: 2
+  }
+};
+
+traverse(schema, {allKeys: true, cb});
+// cb is called 2 times with:
+// 1. root schema
+// 2. mySchema
+```
+
+Without option `allKeys: true` callback will be called only with root schema.

+# schema-utils
+
+Package for validate options in loaders and plugins.
+
+## Getting Started
+
+To begin, you'll need to install `schema-utils`:
+
+```console
+npm install schema-utils
+```
+
+## API
+
+**schema.json**
+
+```json
+{
+  "type": "object",
+  "properties": {
+    "option": {
+      "type": "boolean"
+    }
+  },
+  "additionalProperties": false
+}
+```
+
+```js
+import schema from "./path/to/schema.json";
+import { validate } from "schema-utils";
+
+const options = { option: true };
+const configuration = { name: "Loader Name/Plugin Name/Name" };
+
+validate(schema, options, configuration);
+```
+
+### `schema`
+
+Type: `String`
+
+JSON schema.
+
+Simple example of schema:
+
+```json
+{
+  "type": "object",
+  "properties": {
+    "name": {
+      "description": "This is description of option.",
+      "type": "string"
+    }
+  },
+  "additionalProperties": false
+}
+```
+
+### `options`
+
+Type: `Object`
+
+Object with options.
+
+```js
+import schema from "./path/to/schema.json";
+import { validate } from "schema-utils";
+
+const options = { foo: "bar" };
+
+validate(schema, { name: 123 }, { name: "MyPlugin" });
+```
+
+### `configuration`
+
+Allow to configure validator.
+
+There is an alternative method to configure the `name` and`baseDataPath` options via the `title` property in the schema.
+For example:
+
+```json
+{
+  "title": "My Loader options",
+  "type": "object",
+  "properties": {
+    "name": {
+      "description": "This is description of option.",
+      "type": "string"
+    }
+  },
+  "additionalProperties": false
+}
+```
+
+The last word used for the `baseDataPath` option, other words used for the `name` option.
+Based on the example above the `name` option equals `My Loader`, the `baseDataPath` option equals `options`.
+
+#### `name`
+
+Type: `Object`
+Default: `"Object"`
+
+Allow to setup name in validation errors.
+
+```js
+import schema from "./path/to/schema.json";
+import { validate } from "schema-utils";
+
+const options = { foo: "bar" };
+
+validate(schema, options, { name: "MyPlugin" });
+```
+
+```shell
+Invalid configuration object. MyPlugin has been initialised using a configuration object that does not match the API schema.
+ - configuration.optionName should be a integer.
+```
+
+#### `baseDataPath`
+
+Type: `String`
+Default: `"configuration"`
+
+Allow to setup base data path in validation errors.
+
+```js
+import schema from "./path/to/schema.json";
+import { validate } from "schema-utils";
+
+const options = { foo: "bar" };
+
+validate(schema, options, { name: "MyPlugin", baseDataPath: "options" });
+```
+
+```shell
+Invalid options object. MyPlugin has been initialised using an options object that does not match the API schema.
+ - options.optionName should be a integer.
+```
+
+#### `postFormatter`
+
+Type: `Function`
+Default: `undefined`
+
+Allow to reformat errors.
+
+```js
+import schema from "./path/to/schema.json";
+import { validate } from "schema-utils";
+
+const options = { foo: "bar" };
+
+validate(schema, options, {
+  name: "MyPlugin",
+  postFormatter: (formattedError, error) => {
+    if (error.keyword === "type") {
+      return `${formattedError}\nAdditional Information.`;
+    }
+
+    return formattedError;
+  },
+});
+```
+
+```shell
+Invalid options object. MyPlugin has been initialized using an options object that does not match the API schema.
+ - options.optionName should be a integer.
+   Additional Information.
+```
+
+## Examples
+
+**schema.json**
+
+```json
+{
+  "type": "object",
+  "properties": {
+    "name": {
+      "type": "string"
+    },
+    "test": {
+      "anyOf": [
+        { "type": "array" },
+        { "type": "string" },
+        { "instanceof": "RegExp" }
+      ]
+    },
+    "transform": {
+      "instanceof": "Function"
+    },
+    "sourceMap": {
+      "type": "boolean"
+    }
+  },
+  "additionalProperties": false
+}
+```
+
+### `Loader`
+
+```js
+import { getOptions } from "loader-utils";
+import { validate } from "schema-utils";
+
+import schema from "path/to/schema.json";
+
+function loader(src, map) {
+  const options = getOptions(this);
+
+  validate(schema, options, {
+    name: "Loader Name",
+    baseDataPath: "options",
+  });
+
+  // Code...
+}
+
+export default loader;
+```
+
+### `Plugin`
+
+```js
+import { validate } from "schema-utils";
+
+import schema from "path/to/schema.json";
+
+class Plugin {
+  constructor(options) {
+    validate(schema, options, {
+      name: "Plugin Name",
+      baseDataPath: "options",
+    });
+
+    this.options = options;
+  }
+
+  apply(compiler) {
+    // Code...
+  }
+}
+
+export default Plugin;
+```
