+# react-dev-utils
+
+This package includes some utilities used by [Create React App](https://github.com/facebook/create-react-app).<br>
+Please refer to its documentation:
+
+- [Getting Started](https://facebook.github.io/create-react-app/docs/getting-started) – How to create a new app.
+- [User Guide](https://facebook.github.io/create-react-app/) – How to develop apps bootstrapped with Create React App.
+
+## Usage in Create React App Projects
+
+These utilities come by default with [Create React App](https://github.com/facebook/create-react-app). **You don’t need to install it separately in Create React App projects.**
+
+## Usage Outside of Create React App
+
+If you don’t use Create React App, or if you [ejected](https://facebook.github.io/create-react-app/docs/available-scripts#npm-run-eject), you may keep using these utilities. Their development will be aligned with Create React App, so major versions of these utilities may come out relatively often. Feel free to fork or copy and paste them into your projects if you’d like to have more control over them, or feel free to use the old versions. Not all of them are React-specific, but we might make some of them more React-specific in the future.
+
+### Entry Points
+
+There is no single entry point. You can only import individual top-level modules.
+
+#### `new InterpolateHtmlPlugin(htmlWebpackPlugin: HtmlWebpackPlugin, replacements: {[key:string]: string})`
+
+This webpack plugin lets us interpolate custom variables into `index.html`.<br>
+It works in tandem with [HtmlWebpackPlugin](https://github.com/ampedandwired/html-webpack-plugin) 2.x via its [events](https://github.com/ampedandwired/html-webpack-plugin#events).
+
+```js
+var path = require('path');
+var HtmlWebpackPlugin = require('html-webpack-plugin');
+var InterpolateHtmlPlugin = require('react-dev-utils/InterpolateHtmlPlugin');
+
+// webpack config
+var publicUrl = '/my-custom-url';
+
+module.exports = {
+  output: {
+    // ...
+    publicPath: publicUrl + '/',
+  },
+  // ...
+  plugins: [
+    // Generates an `index.html` file with the <script> injected.
+    new HtmlWebpackPlugin({
+      inject: true,
+      template: path.resolve('public/index.html'),
+    }),
+    // Makes the public URL available as %PUBLIC_URL% in index.html, e.g.:
+    // <link rel="icon" href="%PUBLIC_URL%/favicon.ico">
+    new InterpolateHtmlPlugin(HtmlWebpackPlugin, {
+      PUBLIC_URL: publicUrl,
+      // You can pass any key-value pairs, this was just an example.
+      // WHATEVER: 42 will replace %WHATEVER% with 42 in index.html.
+    }),
+    // ...
+  ],
+  // ...
+};
+```
+
+#### `new InlineChunkHtmlPlugin(htmlWebpackPlugin: HtmlWebpackPlugin, tests: Regex[])`
+
+This webpack plugin inlines script chunks into `index.html`.<br>
+It works in tandem with [HtmlWebpackPlugin](https://github.com/ampedandwired/html-webpack-plugin) 4.x.
+
+```js
+var path = require('path');
+var HtmlWebpackPlugin = require('html-webpack-plugin');
+var InlineChunkHtmlPlugin = require('react-dev-utils/InlineChunkHtmlPlugin');
+
+// webpack config
+var publicUrl = '/my-custom-url';
+
+module.exports = {
+  output: {
+    // ...
+    publicPath: publicUrl + '/',
+  },
+  // ...
+  plugins: [
+    // Generates an `index.html` file with the <script> injected.
+    new HtmlWebpackPlugin({
+      inject: true,
+      template: path.resolve('public/index.html'),
+    }),
+    // Inlines chunks with `runtime` in the name
+    new InlineChunkHtmlPlugin(HtmlWebpackPlugin, [/runtime/]),
+    // ...
+  ],
+  // ...
+};
+```
+
+#### `new ModuleScopePlugin(appSrc: string | string[], allowedFiles?: string[])`
+
+This webpack plugin ensures that relative imports from app's source directories don't reach outside of it.
+
+```js
+var path = require('path');
+var ModuleScopePlugin = require('react-dev-utils/ModuleScopePlugin');
+
+module.exports = {
+  // ...
+  resolve: {
+    // ...
+    plugins: [
+      new ModuleScopePlugin(paths.appSrc, [paths.appPackageJson]),
+      // ...
+    ],
+    // ...
+  },
+  // ...
+};
+```
+
+#### `checkRequiredFiles(files: Array<string>): boolean`
+
+Makes sure that all passed files exist.<br>
+Filenames are expected to be absolute.<br>
+If a file is not found, prints a warning message and returns `false`.
+
+```js
+var path = require('path');
+var checkRequiredFiles = require('react-dev-utils/checkRequiredFiles');
+
+if (
+  !checkRequiredFiles([
+    path.resolve('public/index.html'),
+    path.resolve('src/index.js'),
+  ])
+) {
+  process.exit(1);
+}
+```
+
+#### `clearConsole(): void`
+
+Clears the console, hopefully in a cross-platform way.
+
+```js
+var clearConsole = require('react-dev-utils/clearConsole');
+
+clearConsole();
+console.log('Just cleared the screen!');
+```
+
+#### `eslintFormatter(results: Object): string`
+
+This is our custom ESLint formatter that integrates well with Create React App console output.<br>
+You can use the default one instead if you prefer so.
+
+```js
+const eslintFormatter = require('react-dev-utils/eslintFormatter');
+
+// In your webpack config:
+// ...
+module: {
+  rules: [
+    {
+      test: /\.(js|jsx)$/,
+      include: paths.appSrc,
+      enforce: 'pre',
+      use: [
+        {
+          loader: 'eslint-loader',
+          options: {
+            // Pass the formatter:
+            formatter: eslintFormatter,
+          },
+        },
+      ],
+    },
+  ];
+}
+```
+
+#### `FileSizeReporter`
+
+##### `measureFileSizesBeforeBuild(buildFolder: string): Promise<OpaqueFileSizes>`
+
+Captures JS and CSS asset sizes inside the passed `buildFolder`. Save the result value to compare it after the build.
+
+##### `printFileSizesAfterBuild(webpackStats: WebpackStats, previousFileSizes: OpaqueFileSizes, buildFolder: string, maxBundleGzipSize?: number, maxChunkGzipSize?: number)`
+
+Prints the JS and CSS asset sizes after the build, and includes a size comparison with `previousFileSizes` that were captured earlier using `measureFileSizesBeforeBuild()`. `maxBundleGzipSize` and `maxChunkGzipSizemay` may optionally be specified to display a warning when the main bundle or a chunk exceeds the specified size (in bytes).
+
+```js
+var {
+  measureFileSizesBeforeBuild,
+  printFileSizesAfterBuild,
+} = require('react-dev-utils/FileSizeReporter');
+
+measureFileSizesBeforeBuild(buildFolder).then(previousFileSizes => {
+  return cleanAndRebuild().then(webpackStats => {
+    printFileSizesAfterBuild(webpackStats, previousFileSizes, buildFolder);
+  });
+});
+```
+
+#### `formatWebpackMessages({errors: Array<string>, warnings: Array<string>}): {errors: Array<string>, warnings: Array<string>}`
+
+Extracts and prettifies warning and error messages from webpack [stats](https://github.com/webpack/docs/wiki/node.js-api#stats) object.
+
+```js
+var webpack = require('webpack');
+var config = require('../config/webpack.config.dev');
+var formatWebpackMessages = require('react-dev-utils/formatWebpackMessages');
+
+var compiler = webpack(config);
+
+compiler.hooks.invalid.tap('invalid', function () {
+  console.log('Compiling...');
+});
+
+compiler.hooks.done.tap('done', function (stats) {
+  var rawMessages = stats.toJson({}, true);
+  var messages = formatWebpackMessages(rawMessages);
+  if (!messages.errors.length && !messages.warnings.length) {
+    console.log('Compiled successfully!');
+  }
+  if (messages.errors.length) {
+    console.log('Failed to compile.');
+    messages.errors.forEach(e => console.log(e));
+    return;
+  }
+  if (messages.warnings.length) {
+    console.log('Compiled with warnings.');
+    messages.warnings.forEach(w => console.log(w));
+  }
+});
+```
+
+#### `printBuildError(error: Object): void`
+
+Prettify some known build errors.
+Pass an Error object to log a prettified error message in the console.
+
+```
+  const printBuildError = require('react-dev-utils/printBuildError')
+  try {
+    build()
+  } catch(e) {
+    printBuildError(e) // logs prettified message
+  }
+```
+
+#### `getProcessForPort(port: number): string`
+
+Finds the currently running process on `port`.
+Returns a string containing the name and directory, e.g.,
+
+```
+create-react-app
+in /Users/developer/create-react-app
+```
+
+```js
+var getProcessForPort = require('react-dev-utils/getProcessForPort');
+
+getProcessForPort(3000);
+```
+
+#### `launchEditor(fileName: string, lineNumber: number): void`
+
+On macOS, tries to find a known running editor process and opens the file in it. It can also be explicitly configured by `REACT_EDITOR`, `VISUAL`, or `EDITOR` environment variables. For example, you can put `REACT_EDITOR=atom` in your `.env.local` file, and Create React App will respect that.
+
+#### `noopServiceWorkerMiddleware(servedPath: string): ExpressMiddleware`
+
+Returns Express middleware that serves a `${servedPath}/service-worker.js` that resets any previously set service worker configuration. Useful for development.
+
+#### `redirectServedPathMiddleware(servedPath: string): ExpressMiddleware`
+
+Returns Express middleware that redirects to `${servedPath}/${req.path}`, if `req.url`
+does not start with `servedPath`. Useful for development.
+
+#### `openBrowser(url: string): boolean`
+
+Attempts to open the browser with a given URL.<br>
+On Mac OS X, attempts to reuse an existing Chrome tab via AppleScript.<br>
+Otherwise, falls back to [opn](https://github.com/sindresorhus/opn) behavior.
+
+```js
+var path = require('path');
+var openBrowser = require('react-dev-utils/openBrowser');
+
+if (openBrowser('http://localhost:3000')) {
+  console.log('The browser tab has been opened!');
+}
+```
+
+#### `printHostingInstructions(appPackage: Object, publicUrl: string, publicPath: string, buildFolder: string, useYarn: boolean): void`
+
+Prints hosting instructions after the project is built.
+
+Pass your parsed `package.json` object as `appPackage`, your URL where you plan to host the app as `publicUrl`, `output.publicPath` from your webpack configuration as `publicPath`, the `buildFolder` name, and whether to `useYarn` in instructions.
+
+```js
+const appPackage = require(paths.appPackageJson);
+const publicUrl = paths.publicUrlOrPath;
+const publicPath = config.output.publicPath;
+printHostingInstructions(appPackage, publicUrl, publicPath, 'build', true);
+```
+
+#### `WebpackDevServerUtils`
+
+##### `choosePort(host: string, defaultPort: number): Promise<number | null>`
+
+Returns a Promise resolving to either `defaultPort` or next available port if the user confirms it is okay to do. If the port is taken and the user has refused to use another port, or if the terminal is not interactive and can’t present user with the choice, resolves to `null`.
+
+##### `createCompiler(args: Object): WebpackCompiler`
+
+Creates a webpack compiler instance for WebpackDevServer with built-in helpful messages.
+
+The `args` object accepts a number of properties:
+
+- **appName** `string`: The name that will be printed to the terminal.
+- **config** `Object`: The webpack configuration options to be provided to the webpack constructor.
+- **urls** `Object`: To provide the `urls` argument, use `prepareUrls()` described below.
+- **useYarn** `boolean`: If `true`, yarn instructions will be emitted in the terminal instead of npm.
+- **useTypeScript** `boolean`: If `true`, TypeScript type checking will be enabled. Be sure to provide the `devSocket` argument above if this is set to `true`.
+- **webpack** `function`: A reference to the webpack constructor.
+
+##### `prepareProxy(proxySetting: string, appPublicFolder: string, servedPathname: string): Object`
+
+Creates a WebpackDevServer `proxy` configuration object from the `proxy` setting in `package.json`.
+
+##### `prepareUrls(protocol: string, host: string, port: number, pathname: string = '/'): Object`
+
+Returns an object with local and remote URLs for the development server. Pass this object to `createCompiler()` described above.
+
+#### `webpackHotDevClient`
+
+This is an alternative client for [WebpackDevServer](https://github.com/webpack/webpack-dev-server) that shows a syntax error overlay.
+
+It currently supports only webpack 3.x.
+
+```js
+// webpack development config
+module.exports = {
+  // ...
+  entry: [
+    // You can replace the line below with these two lines if you prefer the
+    // stock client:
+    // require.resolve('webpack-dev-server/client') + '?/',
+    // require.resolve('webpack/hot/dev-server'),
+    'react-dev-utils/webpackHotDevClient',
+    'src/index',
+  ],
+  // ...
+};
+```
+
+#### `getCSSModuleLocalIdent(context: Object, localIdentName: String, localName: String, options: Object): string`
+
+Creates a class name for CSS Modules that uses either the filename or folder name if named `index.module.css`.
+
+For `MyFolder/MyComponent.module.css` and class `MyClass` the output will be `MyComponent.module_MyClass__[hash]`
+For `MyFolder/index.module.css` and class `MyClass` the output will be `MyFolder_MyClass__[hash]`
+
+```js
+const getCSSModuleLocalIdent = require('react-dev-utils/getCSSModuleLocalIdent');
+
+// In your webpack config:
+// ...
+module: {
+  rules: [
+    {
+      test: /\.module\.css$/,
+      use: [
+        require.resolve('style-loader'),
+        {
+          loader: require.resolve('css-loader'),
+          options: {
+            importLoaders: 1,
+            modules: {
+              getLocalIdent: getCSSModuleLocalIdent,
+            },
+          },
+        },
+        {
+          loader: require.resolve('postcss-loader'),
+          options: postCSSLoaderOptions,
+        },
+      ],
+    },
+  ];
+}
+```
+
+#### `getCacheIdentifier(environment: string, packages: string[]): string`
+
+Returns a cache identifier (string) consisting of the specified environment and related package versions, e.g.,
+
+```js
+var getCacheIdentifier = require('react-dev-utils/getCacheIdentifier');
+
+getCacheIdentifier('prod', ['react-dev-utils', 'chalk']); // # => 'prod:react-dev-utils@5.0.0:chalk@3.0.0'
+```

+
+> [ANSI escape codes](https://en.wikipedia.org/wiki/ANSI_escape_code#Colors_and_Styles) for styling strings in the terminal
+
+You probably want the higher-level [chalk](https://github.com/chalk/chalk) module for styling your strings.
+
+<img src="screenshot.svg" width="900">
+
+## Install
+
+```
+$ npm install ansi-styles
+```
+
+## Usage
+
+```js
+const style = require('ansi-styles');
+
+console.log(`${style.green.open}Hello world!${style.green.close}`);
+
+
+// Color conversion between 16/256/truecolor
+// NOTE: If conversion goes to 16 colors or 256 colors, the original color
+//       may be degraded to fit that color palette. This means terminals
+//       that do not support 16 million colors will best-match the
+//       original color.
+console.log(style.bgColor.ansi.hsl(120, 80, 72) + 'Hello world!' + style.bgColor.close);
+console.log(style.color.ansi256.rgb(199, 20, 250) + 'Hello world!' + style.color.close);
+console.log(style.color.ansi16m.hex('#abcdef') + 'Hello world!' + style.color.close);
+```
+
+## API
+
+Each style has an `open` and `close` property.
+
+## Styles
+
+### Modifiers
+
+- `reset`
+- `bold`
+- `dim`
+- `italic` *(Not widely supported)*
+- `underline`
+- `inverse`
+- `hidden`
+- `strikethrough` *(Not widely supported)*
+
+### Colors
+
+- `black`
+- `red`
+- `green`
+- `yellow`
+- `blue`
+- `magenta`
+- `cyan`
+- `white`
+- `blackBright` (alias: `gray`, `grey`)
+- `redBright`
+- `greenBright`
+- `yellowBright`
+- `blueBright`
+- `magentaBright`
+- `cyanBright`
+- `whiteBright`
+
+### Background colors
+
+- `bgBlack`
+- `bgRed`
+- `bgGreen`
+- `bgYellow`
+- `bgBlue`
+- `bgMagenta`
+- `bgCyan`
+- `bgWhite`
+- `bgBlackBright` (alias: `bgGray`, `bgGrey`)
+- `bgRedBright`
+- `bgGreenBright`
+- `bgYellowBright`
+- `bgBlueBright`
+- `bgMagentaBright`
+- `bgCyanBright`
+- `bgWhiteBright`
+
+## Advanced usage
+
+By default, you get a map of styles, but the styles are also available as groups. They are non-enumerable so they don't show up unless you access them explicitly. This makes it easier to expose only a subset in a higher-level module.
+
+- `style.modifier`
+- `style.color`
+- `style.bgColor`
+
+###### Example
+
+```js
+console.log(style.color.green.open);
+```
+
+Raw escape codes (i.e. without the CSI escape prefix `\u001B[` and render mode postfix `m`) are available under `style.codes`, which returns a `Map` with the open codes as keys and close codes as values.
+
+###### Example
+
+```js
+console.log(style.codes.get(36));
+//=> 39
+```
+
+## [256 / 16 million (TrueColor) support](https://gist.github.com/XVilka/8346728)
+
+`ansi-styles` uses the [`color-convert`](https://github.com/Qix-/color-convert) package to allow for converting between various colors and ANSI escapes, with support for 256 and 16 million colors.
+
+The following color spaces from `color-convert` are supported:
+
+- `rgb`
+- `hex`
+- `keyword`
+- `hsl`
+- `hsv`
+- `hwb`
+- `ansi`
+- `ansi256`
+
+To use these, call the associated conversion function with the intended output, for example:
+
+```js
+style.color.ansi.rgb(100, 200, 15); // RGB to 16 color ansi foreground code
+style.bgColor.ansi.rgb(100, 200, 15); // RGB to 16 color ansi background code
+
+style.color.ansi256.hsl(120, 100, 60); // HSL to 256 color ansi foreground code
+style.bgColor.ansi256.hsl(120, 100, 60); // HSL to 256 color ansi foreground code
+
+style.color.ansi16m.hex('#C0FFEE'); // Hex (RGB) to 16 million color foreground code
+style.bgColor.ansi16m.hex('#C0FFEE'); // Hex (RGB) to 16 million color background code
+```

+## Highlights
+
+- Expressive API
+- Highly performant
+- Ability to nest styles
+- [256/Truecolor color support](#256-and-truecolor-color-support)
+- Auto-detects color support
+- Doesn't extend `String.prototype`
+- Clean and focused
+- Actively maintained
+- [Used by ~50,000 packages](https://www.npmjs.com/browse/depended/chalk) as of January 1, 2020
+
+## Install
+
+```console
+$ npm install chalk
+```
+
+## Usage
+
+```js
+const chalk = require('chalk');
+
+console.log(chalk.blue('Hello world!'));
+```
+
+Chalk comes with an easy to use composable API where you just chain and nest the styles you want.
+
+```js
+const chalk = require('chalk');
+const log = console.log;
+
+// Combine styled and normal strings
+log(chalk.blue('Hello') + ' World' + chalk.red('!'));
+
+// Compose multiple styles using the chainable API
+log(chalk.blue.bgRed.bold('Hello world!'));
+
+// Pass in multiple arguments
+log(chalk.blue('Hello', 'World!', 'Foo', 'bar', 'biz', 'baz'));
+
+// Nest styles
+log(chalk.red('Hello', chalk.underline.bgBlue('world') + '!'));
+
+// Nest styles of the same type even (color, underline, background)
+log(chalk.green(
+	'I am a green line ' +
+	chalk.blue.underline.bold('with a blue substring') +
+	' that becomes green again!'
+));
+
+// ES2015 template literal
+log(`
+CPU: ${chalk.red('90%')}
+RAM: ${chalk.green('40%')}
+DISK: ${chalk.yellow('70%')}
+`);
+
+// ES2015 tagged template literal
+log(chalk`
+CPU: {red ${cpu.totalPercent}%}
+RAM: {green ${ram.used / ram.total * 100}%}
+DISK: {rgb(255,131,0) ${disk.used / disk.total * 100}%}
+`);
+
+// Use RGB colors in terminal emulators that support it.
+log(chalk.keyword('orange')('Yay for orange colored text!'));
+log(chalk.rgb(123, 45, 67).underline('Underlined reddish color'));
+log(chalk.hex('#DEADED').bold('Bold gray!'));
+```
+
+Easily define your own themes:
+
+```js
+const chalk = require('chalk');
+
+const error = chalk.bold.red;
+const warning = chalk.keyword('orange');
+
+console.log(error('Error!'));
+console.log(warning('Warning!'));
+```
+
+Take advantage of console.log [string substitution](https://nodejs.org/docs/latest/api/console.html#console_console_log_data_args):
+
+```js
+const name = 'Sindre';
+console.log(chalk.green('Hello %s'), name);
+//=> 'Hello Sindre'
+```
+
+## API
+
+### chalk.`<style>[.<style>...](string, [string...])`
+
+Example: `chalk.red.bold.underline('Hello', 'world');`
+
+Chain [styles](#styles) and call the last one as a method with a string argument. Order doesn't matter, and later styles take precedent in case of a conflict. This simply means that `chalk.red.yellow.green` is equivalent to `chalk.green`.
+
+Multiple arguments will be separated by space.
+
+### chalk.level
+
+Specifies the level of color support.
+
+Color support is automatically detected, but you can override it by setting the `level` property. You should however only do this in your own code as it applies globally to all Chalk consumers.
+
+If you need to change this in a reusable module, create a new instance:
+
+```js
+const ctx = new chalk.Instance({level: 0});
+```
+
+| Level | Description |
+| :---: | :--- |
+| `0` | All colors disabled |
+| `1` | Basic color support (16 colors) |
+| `2` | 256 color support |
+| `3` | Truecolor support (16 million colors) |
+
+### chalk.supportsColor
+
+Detect whether the terminal [supports color](https://github.com/chalk/supports-color). Used internally and handled for you, but exposed for convenience.
+
+Can be overridden by the user with the flags `--color` and `--no-color`. For situations where using `--color` is not possible, use the environment variable `FORCE_COLOR=1` (level 1), `FORCE_COLOR=2` (level 2), or `FORCE_COLOR=3` (level 3) to forcefully enable color, or `FORCE_COLOR=0` to forcefully disable. The use of `FORCE_COLOR` overrides all other color support checks.
+
+Explicit 256/Truecolor mode can be enabled using the `--color=256` and `--color=16m` flags, respectively.
+
+### chalk.stderr and chalk.stderr.supportsColor
+
+`chalk.stderr` contains a separate instance configured with color support detected for `stderr` stream instead of `stdout`. Override rules from `chalk.supportsColor` apply to this too. `chalk.stderr.supportsColor` is exposed for convenience.
+
+## Styles
+
+### Modifiers
+
+- `reset` - Resets the current color chain.
+- `bold` - Make text bold.
+- `dim` - Emitting only a small amount of light.
+- `italic` - Make text italic. *(Not widely supported)*
+- `underline` - Make text underline. *(Not widely supported)*
+- `inverse`- Inverse background and foreground colors.
+- `hidden` - Prints the text, but makes it invisible.
+- `strikethrough` - Puts a horizontal line through the center of the text. *(Not widely supported)*
+- `visible`- Prints the text only when Chalk has a color level > 0. Can be useful for things that are purely cosmetic.
+
+### Colors
+
+- `black`
+- `red`
+- `green`
+- `yellow`
+- `blue`
+- `magenta`
+- `cyan`
+- `white`
+- `blackBright` (alias: `gray`, `grey`)
+- `redBright`
+- `greenBright`
+- `yellowBright`
+- `blueBright`
+- `magentaBright`
+- `cyanBright`
+- `whiteBright`
+
+### Background colors

+- `bgWhiteBright`
+
+## Tagged template literal
+
+Chalk can be used as a [tagged template literal](https://exploringjs.com/es6/ch_template-literals.html#_tagged-template-literals).
+
+```js
+const chalk = require('chalk');
+
+const miles = 18;
+const calculateFeet = miles => miles * 5280;
+
+console.log(chalk`
+	There are {bold 5280 feet} in a mile.
+	In {bold ${miles} miles}, there are {green.bold ${calculateFeet(miles)} feet}.
+`);
+```
+
+Blocks are delimited by an opening curly brace (`{`), a style, some content, and a closing curly brace (`}`).
+
+Template styles are chained exactly like normal Chalk styles. The following three statements are equivalent:
+
+```js
+console.log(chalk.bold.rgb(10, 100, 200)('Hello!'));
+console.log(chalk.bold.rgb(10, 100, 200)`Hello!`);
+console.log(chalk`{bold.rgb(10,100,200) Hello!}`);
+```
+
+Note that function styles (`rgb()`, `hsl()`, `keyword()`, etc.) may not contain spaces between parameters.
+
+All interpolated values (`` chalk`${foo}` ``) are converted to strings via the `.toString()` method. All curly braces (`{` and `}`) in interpolated value strings are escaped.
+
+## 256 and Truecolor color support
+
+Chalk supports 256 colors and [Truecolor](https://gist.github.com/XVilka/8346728) (16 million colors) on supported terminal apps.
+
+Colors are downsampled from 16 million RGB values to an ANSI color format that is supported by the terminal emulator (or by specifying `{level: n}` as a Chalk option). For example, Chalk configured to run at level 1 (basic color support) will downsample an RGB value of #FF0000 (red) to 31 (ANSI escape for red).
+
+Examples:
+
+- `chalk.hex('#DEADED').underline('Hello, world!')`
+- `chalk.keyword('orange')('Some orange text')`
+- `chalk.rgb(15, 100, 204).inverse('Hello!')`
+
+Background versions of these models are prefixed with `bg` and the first level of the module capitalized (e.g. `keyword` for foreground colors and `bgKeyword` for background colors).
+
+- `chalk.bgHex('#DEADED').underline('Hello, world!')`
+- `chalk.bgKeyword('orange')('Some orange text')`
+- `chalk.bgRgb(15, 100, 204).inverse('Hello!')`
+
+The following color models can be used:
+
+- [`rgb`](https://en.wikipedia.org/wiki/RGB_color_model) - Example: `chalk.rgb(255, 136, 0).bold('Orange!')`
+- [`hex`](https://en.wikipedia.org/wiki/Web_colors#Hex_triplet) - Example: `chalk.hex('#FF8800').bold('Orange!')`
+- [`keyword`](https://www.w3.org/wiki/CSS/Properties/color/keywords) (CSS keywords) - Example: `chalk.keyword('orange').bold('Orange!')`
+- [`hsl`](https://en.wikipedia.org/wiki/HSL_and_HSV) - Example: `chalk.hsl(32, 100, 50).bold('Orange!')`
+- [`hsv`](https://en.wikipedia.org/wiki/HSL_and_HSV) - Example: `chalk.hsv(32, 100, 100).bold('Orange!')`
+- [`hwb`](https://en.wikipedia.org/wiki/HWB_color_model) - Example: `chalk.hwb(32, 0, 50).bold('Orange!')`
+- [`ansi`](https://en.wikipedia.org/wiki/ANSI_escape_code#3/4_bit) - Example: `chalk.ansi(31).bgAnsi(93)('red on yellowBright')`
+- [`ansi256`](https://en.wikipedia.org/wiki/ANSI_escape_code#8-bit) - Example: `chalk.bgAnsi256(194)('Honeydew, more or less')`
+
+## Windows
+
+If you're on Windows, do yourself a favor and use [Windows Terminal](https://github.com/microsoft/terminal) instead of `cmd.exe`.
+
+## Origin story
+
+[colors.js](https://github.com/Marak/colors.js) used to be the most popular string styling module, but it has serious deficiencies like extending `String.prototype` which causes all kinds of [problems](https://github.com/yeoman/yo/issues/68) and the package is unmaintained. Although there are other packages, they either do too much or not enough. Chalk is a clean and focused alternative.
+
+## chalk for enterprise

+# color-convert
+
+[![Build Status](https://travis-ci.org/Qix-/color-convert.svg?branch=master)](https://travis-ci.org/Qix-/color-convert)
+
+Color-convert is a color conversion library for JavaScript and node.
+It converts all ways between `rgb`, `hsl`, `hsv`, `hwb`, `cmyk`, `ansi`, `ansi16`, `hex` strings, and CSS `keyword`s (will round to closest):
+
+```js
+var convert = require('color-convert');
+
+convert.rgb.hsl(140, 200, 100);             // [96, 48, 59]
+convert.keyword.rgb('blue');                // [0, 0, 255]
+
+var rgbChannels = convert.rgb.channels;     // 3
+var cmykChannels = convert.cmyk.channels;   // 4
+var ansiChannels = convert.ansi16.channels; // 1
+```
+
+# Install
+
+```console
+$ npm install color-convert
+```
+
+# API
+
+Simply get the property of the _from_ and _to_ conversion that you're looking for.
+
+All functions have a rounded and unrounded variant. By default, return values are rounded. To get the unrounded (raw) results, simply tack on `.raw` to the function.
+
+All 'from' functions have a hidden property called `.channels` that indicates the number of channels the function expects (not including alpha).
+
+```js
+var convert = require('color-convert');
+
+// Hex to LAB
+convert.hex.lab('DEADBF');         // [ 76, 21, -2 ]
+convert.hex.lab.raw('DEADBF');     // [ 75.56213190997677, 20.653827952644754, -2.290532499330533 ]
+
+// RGB to CMYK
+convert.rgb.cmyk(167, 255, 4);     // [ 35, 0, 98, 0 ]
+convert.rgb.cmyk.raw(167, 255, 4); // [ 34.509803921568626, 0, 98.43137254901961, 0 ]
+```
+
+### Arrays
+All functions that accept multiple arguments also support passing an array.
+
+Note that this does **not** apply to functions that convert from a color that only requires one value (e.g. `keyword`, `ansi256`, `hex`, etc.)
+
+```js
+var convert = require('color-convert');
+
+convert.rgb.hex(123, 45, 67);      // '7B2D43'
+convert.rgb.hex([123, 45, 67]);    // '7B2D43'
+```
+
+## Routing
+
+Conversions that don't have an _explicitly_ defined conversion (in [conversions.js](conversions.js)), but can be converted by means of sub-conversions (e.g. XYZ -> **RGB** -> CMYK), are automatically routed together. This allows just about any color model supported by `color-convert` to be converted to any other model, so long as a sub-conversion path exists. This is also true for conversions requiring more than one step in between (e.g. LCH -> **LAB** -> **XYZ** -> **RGB** -> Hex).
+
+Keep in mind that extensive conversions _may_ result in a loss of precision, and exist only to be complete. For a list of "direct" (single-step) conversions, see [conversions.js](conversions.js).
+
+# Contribute
+
+If there is a new model you would like to support, or want to add a direct conversion between two existing models, please send us a pull request.

+
+## Methods
+
+### `urlToRequest`
+
+Converts some resource URL to a webpack module request.
+
+> i Before call `urlToRequest` you need call `isUrlRequest` to ensure it is requestable url
+
+```javascript
+const url = "path/to/module.js";
+
+if (loaderUtils.isUrlRequest(url)) {
+  // Logic for requestable url
+  const request = loaderUtils.urlToRequest(url);
+} else {
+  // Logic for not requestable url
+}
+```
+
+Simple example:
+
+```javascript
+const url = "path/to/module.js";
+const request = loaderUtils.urlToRequest(url); // "./path/to/module.js"
+```
+
+#### Module URLs
+
+Any URL containing a `~` will be interpreted as a module request. Anything after the `~` will be considered the request path.
+
+```javascript
+const url = "~path/to/module.js";
+const request = loaderUtils.urlToRequest(url); // "path/to/module.js"
+```
+
+#### Root-relative URLs
+
+URLs that are root-relative (start with `/`) can be resolved relative to some arbitrary path by using the `root` parameter:
+
+```javascript
+const url = "/path/to/module.js";
+const root = "./root";
+const request = loaderUtils.urlToRequest(url, root); // "./root/path/to/module.js"
+```
+
+To convert a root-relative URL into a module URL, specify a `root` value that starts with `~`:
+
+```javascript
+const url = "/path/to/module.js";
+const root = "~";
+const request = loaderUtils.urlToRequest(url, root); // "path/to/module.js"
+```
+
+### `interpolateName`
+
+Interpolates a filename template using multiple placeholders and/or a regular expression.
+The template and regular expression are set as query params called `name` and `regExp` on the current loader's context.
+
+```javascript
+const interpolatedName = loaderUtils.interpolateName(
+  loaderContext,
+  name,
+  options
+);
+```
+
+The following tokens are replaced in the `name` parameter:
+
+- `[ext]` the extension of the resource
+- `[name]` the basename of the resource
+- `[path]` the path of the resource relative to the `context` query parameter or option.
+- `[folder]` the folder the resource is in
+- `[query]` the queryof the resource, i.e. `?foo=bar`
+- `[contenthash]` the hash of `options.content` (Buffer) (by default it's the hex digest of the `xxhash64` hash)
+- `[<hashType>:contenthash:<digestType>:<length>]` optionally one can configure
+  - other `hashType`s, i. e. `xxhash64`, `sha1`, `md4` (wasm version), `native-md4` (`crypto` module version), `md5`, `sha256`, `sha512`
+  - other `digestType`s, i. e. `hex`, `base26`, `base32`, `base36`, `base49`, `base52`, `base58`, `base62`, `base64`
+  - and `length` the length in chars
+- `[hash]` the hash of `options.content` (Buffer) (by default it's the hex digest of the `xxhash64` hash)
+- `[<hashType>:hash:<digestType>:<length>]` optionally one can configure
+  - other `hashType`s, i. e. `xxhash64`, `sha1`, `md4` (wasm version), `native-md4` (`crypto` module version), `md5`, `sha256`, `sha512`
+  - other `digestType`s, i. e. `hex`, `base26`, `base32`, `base36`, `base49`, `base52`, `base58`, `base62`, `base64`
+  - and `length` the length in chars
+- `[N]` the N-th match obtained from matching the current file name against `options.regExp`
+
+In loader context `[hash]` and `[contenthash]` are the same, but we recommend using `[contenthash]` for avoid misleading.
+

+
+### `getHashDigest`
+
+```javascript
+const digestString = loaderUtils.getHashDigest(
+  buffer,
+  hashType,
+  digestType,
+  maxLength
+);
+```
+
+- `buffer` the content that should be hashed
+- `hashType` one of `xxhash64`, `sha1`, `md4`, `md5`, `sha256`, `sha512` or any other node.js supported hash type
+- `digestType` one of `hex`, `base26`, `base32`, `base36`, `base49`, `base52`, `base58`, `base62`, `base64`
+- `maxLength` the maximum length in chars

+# supports-color [![Build Status](https://travis-ci.org/chalk/supports-color.svg?branch=master)](https://travis-ci.org/chalk/supports-color)
+
+> Detect whether a terminal supports color
+
+
+## Install
+
+```
+$ npm install supports-color
+```
+
+
+## Usage
+
+```js
+const supportsColor = require('supports-color');
+
+if (supportsColor.stdout) {
+	console.log('Terminal stdout supports color');
+}
+
+if (supportsColor.stdout.has256) {
+	console.log('Terminal stdout supports 256 colors');
+}
+
+if (supportsColor.stderr.has16m) {
+	console.log('Terminal stderr supports 16 million colors (truecolor)');
+}
+```
+
+
+## API
+
+Returns an `Object` with a `stdout` and `stderr` property for testing either streams. Each property is an `Object`, or `false` if color is not supported.
+
+The `stdout`/`stderr` objects specifies a level of support for color through a `.level` property and a corresponding flag:
+
+- `.level = 1` and `.hasBasic = true`: Basic color support (16 colors)
+- `.level = 2` and `.has256 = true`: 256 color support
+- `.level = 3` and `.has16m = true`: Truecolor support (16 million colors)
+
+
+## Info
+
+It obeys the `--color` and `--no-color` CLI flags.
+
+For situations where using `--color` is not possible, use the environment variable `FORCE_COLOR=1` (level 1), `FORCE_COLOR=2` (level 2), or `FORCE_COLOR=3` (level 3) to forcefully enable color, or `FORCE_COLOR=0` to forcefully disable. The use of `FORCE_COLOR` overrides all other color support checks.
+
+Explicit 256/Truecolor mode can be enabled using the `--color=256` and `--color=16m` flags, respectively.
