For example:\n\n**file.js**\n\n```js\nimport css from \"file.css\";\n```\n\n**webpack.config.js**\n\n```js\nmodule.exports = {\n module: {\n rules: [\n {\n test: /\\.css$/i,\n use: [\"style-loader\", \"css-loader\"],\n },\n ],\n },\n};\n```\n\nAnd run `webpack` via your preferred method.\n\nIf, for one reason or another, you need to extract CSS as a file (i.e. do not store CSS in a JS module) you might want to check out the [recommend example](https://github.com/webpack-contrib/css-loader#recommend).\n\n## Options\n\n- **[`url`](#url)**\n- **[`import`](#import)**\n- **[`modules`](#modules)**\n- **[`sourceMap`](#sourcemap)**\n- **[`importLoaders`](#importloaders)**\n- **[`esModule`](#esmodule)**\n- **[`exportType`](#exporttype)**\n\n### `url`\n\nType:\n\n```ts\ntype url =\n | boolean\n | {\n filter: (url: string, resourcePath: string) => boolean;\n };\n```\n\nDefault: `true`\n\nAllow to enable/disables handling the CSS functions `url` and `image-set`.\nIf set to `false`, `css-loader` will not parse any paths specified in `url` or `image-set`.\nA function can also be passed to control this behavior dynamically based on the path to the asset.\nStarting with version [4.0.0](https://github.com/webpack-contrib/css-loader/blob/master/CHANGELOG.md#400-2020-07-25), absolute paths are parsed based on the server root.\n\nExamples resolutions:\n\n```js\nurl(image.png) => require('./image.png')\nurl('image.png') => require('./image.png')\nurl(./image.png) => require('./image.png')\nurl('./image.png') => require('./image.png')\nurl('http://dontwritehorriblecode.com/2112.png') => require('http://dontwritehorriblecode.com/2112.png')\nimage-set(url('image2x.png') 1x, url('image1x.png') 2x) => require('./image1x.png') and require('./image2x.png')\n```\n\nTo import assets from a `node_modules` path (include `resolve.modules`) and for `alias`, prefix it with a `~`:\n\n```js\nurl(~module/image.png) => require('module/image.png')\nurl('~module/image.png') => require('module/image.png')\nurl(~aliasDirectory/image.png) => require('otherDirectory/image.png')\n```\n\n#### `boolean`\n\nEnable/disable `url()` resolving.\n\n**webpack.config.js**\n\n```js\nmodule.exports = {\n module: {\n rules: [\n {\n test: /\\.css$/i,\n loader: \"css-loader\",\n options: {\n url: true,\n },\n },\n ],\n },\n};\n```\n\n#### `object`\n\nAllow to filter `url()`.

Absolute urls in `@import` will be moved in runtime code.\n\nExamples resolutions:\n\n```\n@import 'style.css' => require('./style.css')\n@import url(style.css) => require('./style.css')\n@import url('style.css') => require('./style.css')\n@import './style.css' => require('./style.css')\n@import url(./style.css) => require('./style.css')\n@import url('./style.css') => require('./style.css')\n@import url('http://dontwritehorriblecode.com/style.css') => @import url('http://dontwritehorriblecode.com/style.css') in runtime\n```\n\nTo import styles from a `node_modules` path (include `resolve.modules`) and for `alias`, prefix it with a `~`:\n\n```\n@import url(~module/style.css) => require('module/style.css')\n@import url('~module/style.css') => require('module/style.css')\n@import url(~aliasDirectory/style.css) => require('otherDirectory/style.css')\n```\n\n#### `boolean`\n\nEnable/disable `@import` resolving.\n\n**webpack.config.js**\n\n```js\nmodule.exports = {\n module: {\n rules: [\n {\n test: /\\.css$/i,\n loader: \"css-loader\",\n options: {\n import: true,\n },\n },\n ],\n },\n};\n```\n\n#### `object`\n\n##### `filter`\n\nType:\n\n```ts\ntype filter = (url: string, media: string, resourcePath: string) => boolean;\n```\n\nDefault: `undefined`\n\nAllow to filter `@import`. All filtered `@import` will not be resolved (left in the code as they were written).\n\n**webpack.config.js**\n\n```js\nmodule.exports = {\n module: {\n rules: [\n {\n test: /\\.css$/i,\n loader: \"css-loader\",\n options: {\n import: {\n filter: (url, media, resourcePath) => {\n // resourcePath - path to css file\n\n // Don't handle `style.css` import\n if (url.includes(\"style.css\")) {\n return false;\n }\n\n return true;\n },\n },\n },\n },\n ],\n },\n};\n```\n\n### `modules`\n\nType:\n\n```ts\ntype modules =\n | boolean\n | \"local\"\n | \"global\"\n | \"pure\"\n | \"icss\"\n | {\n auto: boolean | regExp | ((resourcePath: string) => boolean);\n mode:\n | \"local\"\n | \"global\"\n | \"pure\"\n | \"icss\"\n | ((resourcePath) => \"local\" | \"global\" | \"pure\" | \"icss\");\n localIdentName: string;\n localIdentContext: string;\n localIdentHashSalt: string;\n localIdentHashFunction: string;\n localIdentHashDigest: string;\n localIdentRegExp: string | regExp;\n getLocalIdent: (\n context: LoaderContext,\n localIdentName: string,\n localName: string\n ) => string;\n namedExport: boolean;\n exportGlobals: boolean;\n exportLocalsConvention:\n | \"asIs\"\n | \"camelCase\"\n | \"camelCaseOnly\"\n | \"dashes\"\n | \"dashesOnly\"\n | ((name: string) => string);\n exportOnlyLocals: boolean;\n };\n```\n\nDefault: `undefined`\n\nAllows to enable/disable CSS Modules or ICSS and setup configuration:\n\n- `undefined` - enable CSS modules for all files matching `/\\.module\\.\\w+$/i.test(filename)` and `/\\.icss\\.\\w+$/i.test(filename)` regexp.\n- `true` - enable CSS modules for all files.\n- `false` - disables CSS Modules for all files.\n- `string` - disables CSS Modules for all files and set the `mode` option, more information you can read [here](https://github.com/webpack-contrib/css-loader#mode)\n- `object` - enable CSS modules for all files, if `modules.auto` option is not specified, otherwise the `modules.auto` option will determine whether if it is CSS modules or not, more information you can read [here](https://github.com/webpack-contrib/css-loader#auto)\n\nThe `modules` option enables/disables the **[CSS Modules](https://github.com/css-modules/css-modules)** specification and setup basic behaviour.\n\nUsing `false` value increase performance because we avoid parsing **CSS Modules** features, it will be useful for developers who use vanilla css or use other technologies.\n\n**webpack.config.js**\n\n```js\nmodule.exports = {\n module: {\n rules: [\n {\n test: /\\.css$/i,\n loader: \"css-loader\",\n options: {\n modules: true,\n },\n },\n ],\n },\n};\n```\n\n#### `Features`\n\n##### `Scope`\n\nUsing `local` value requires you to specify `:global` classes.\nUsing `global` value requires you to specify `:local` classes.\nUsing `pure` value requires selectors must contain at least one local class or id.\n\nYou can find more information [here](https://github.com/css-modules/css-modules).\n\nStyles can be locally scoped to avoid globally scoping styles.\n\nThe syntax `:local(.className)` can be used to declare `className` in the local scope. The local identifiers are exported by the module.\n\nWith `:local` (without brackets) local mode can be switched on for this selector.\nThe `:global(.className)` notation can be used to declare an explicit global selector.\nWith `:global` (without brackets) global mode can be switched on for this selector.\n\nThe loader replaces local selectors with unique identifiers. The chosen unique identifiers are exported by the module.\n\n```css\n:local(.className) {\n background: red;\n}\n:local .className {\n color: green;\n}\n:local(.className .subClass) {\n color: green;\n}\n:local .className .subClass :global(.global-class-name) {\n color: blue;\n}\n```\n\n```css\n._23_aKvs-b8bW2Vg3fwHozO {\n background: red;\n}\n._23_aKvs-b8bW2Vg3fwHozO {\n color: green;\n}\n._23_aKvs-b8bW2Vg3fwHozO ._13LGdX8RMStbBE9w-t0gZ1 {\n color: green;\n}\n._23_aKvs-b8bW2Vg3fwHozO ._13LGdX8RMStbBE9w-t0gZ1 .global-class-name {\n color: blue;\n}\n```\n\n> **Note**\n>\n> Identifiers are exported\n\n```js\nexports.locals = {\n className: \"_23_aKvs-b8bW2Vg3fwHozO\",\n subClass: \"_13LGdX8RMStbBE9w-t0gZ1\",\n};\n```\n\nCamelCase is recommended for local selectors. They are easier to use within the imported JS module.\n\nYou can use `:local(#someId)`, but this is not recommended. Use classes instead of ids.\n\n##### `Composing`\n\nWhen declaring a local classname you can compose a local class from another local classname.\n\n```css\n:local(.className) {\n background: red;\n color: yellow;\n}\n\n:local(.subClass) {\n composes: className;\n background: blue;\n}\n```\n\nThis doesn't result in any change to the CSS itself but exports multiple classnames.\n\n```js\nexports.locals = {\n className: \"_23_aKvs-b8bW2Vg3fwHozO\",\n subClass: \"_13LGdX8RMStbBE9w-t0gZ1 _23_aKvs-b8bW2Vg3fwHozO\",\n};\n```\n\n```css\n._23_aKvs-b8bW2Vg3fwHozO {\n background: red;\n color: yellow;\n}\n\n._13LGdX8RMStbBE9w-t0gZ1 {\n background: blue;\n}\n```\n\n##### `Importing`\n\nTo import a local classname from another module.\n\n> **Note**\n>\n> We strongly recommend that you specify the extension when importing a file, since it is possible to import a file with any extension and it is not known in advance which file to use.\n\n```css\n:local(.continueButton) {\n composes: button from \"library/button.css\";\n background: red;\n}\n```\n\n```css\n:local(.nameEdit) {\n composes: edit highlight from \"./edit.css\";\n background: red;\n}\n```\n\nTo import from multiple modules use multiple `composes:` rules.\n\n```css\n:local(.className) {\n composes: edit highlight from \"./edit.css\", button from \"module/button.css\", classFromThisModule;\n background: red;\n}\n```\n\nor\n\n```css\n:local(.className) {\n composes: edit highlight from \"./edit.css\";\n composes: button from \"module/button.css\";\n composes: classFromThisModule;\n background: red;\n}\n```\n\n##### `Values`\n\nYou can use `@value` to specific values to be reused throughout a document.\n\nWe recommend use prefix `v-` for values, `s-` for selectors and `m-` for media at-rules.\n\n```css\n@value v-primary: #BF4040;\n@value s-black: black-selector;\n@value m-large: (min-width: 960px);\n\n.header {\n color: v-primary;\n padding: 0 10px;\n}\n\n.s-black {\n color: black;\n}\n\n@media m-large {\n .header {\n padding: 0 20px;\n }\n}\n```\n\n#### `boolean`\n\nEnable **CSS Modules** features.\n\n**webpack.config.js**\n\n```js\nmodule.exports = {\n module: {\n rules: [\n {\n test: /\\.css$/i,\n loader: \"css-loader\",\n options: {\n modules: true,\n },\n },\n ],\n },\n};\n```\n\n#### `string`\n\nEnable **CSS Modules** features and setup `mode`.\n\n**webpack.config.js**\n\n```js\nmodule.exports = {\n module: {\n rules: [\n {\n test: /\\.css$/i,\n loader: \"css-loader\",\n options: {\n // Using `local` value has same effect like using `modules: true`\n modules: \"global\",\n },\n },\n ],\n },\n};\n```\n\n#### `object`\n\nEnable **CSS Modules** features and setup options for them.\n\n**webpack.config.js**\n\n```js\nmodule.exports = {\n module: {\n rules: [\n {\n test: /\\.css$/i,\n loader: \"css-loader\",\n options: {\n modules: {\n mode: \"local\",\n auto: true,\n exportGlobals: true,\n localIdentName: \"[path][name]__[local]--[hash:base64:5]\",\n localIdentContext: path.resolve(__dirname, \"src\"),\n localIdentHashSalt: \"my-custom-hash\",\n namedExport: true,\n exportLocalsConvention: \"camelCase\",\n exportOnlyLocals: false,\n },\n },\n },\n ],\n },\n};\n```\n\n##### `auto`\n\nType:\n\n```ts\ntype auto =\n | boolean\n | regExp\n | ((\n resourcePath: string,\n resourceQuery: string,\n resourceFragment: string\n ) => boolean);\n```\n\nDefault: `undefined`\n\nAllows auto enable CSS modules/ICSS based on the filename, query or fragment when `modules` option is object.\n\nPossible values:\n\n- `undefined` - enable CSS modules for all files.\n- `true` - enable CSS modules for all files matching `/\\.module\\.\\w+$/i.test(filename)` and `/\\.icss\\.\\w+$/i.test(filename)` regexp.\n- `false` - disables CSS Modules.\n- `RegExp` - enable CSS modules for all files matching `/RegExp/i.test(filename)` regexp.\n- `function` - enable CSS Modules for files based on the filename satisfying your filter function check.\n\n###### `boolean`\n\nPossible values:\n\n- `true` - enables CSS modules or interoperable CSS format, sets the [`modules.mode`](#mode) option to `local` value for all files which satisfy `/\\.module(s)?\\.\\w+$/i.test(filename)` condition or sets the [`modules.mode`](#mode) option to `icss` value for all files which satisfy `/\\.icss\\.\\w+$/i.test(filename)` condition\n- `false` - disables CSS modules or interoperable CSS format based on filename\n\n**webpack.config.js**\n\n```js\nmodule.exports = {\n module: {\n rules: [\n {\n test: /\\.css$/i,\n loader: \"css-loader\",\n options: {\n modules: {\n auto: true,\n },\n },\n },\n ],\n },\n};\n```\n\n###### `RegExp`\n\nEnable CSS modules for files based on the filename satisfying your regex check.\n\n**webpack.config.js**\n\n```js\nmodule.exports = {\n module: {\n rules: [\n {\n test: /\\.css$/i,\n loader: \"css-loader\",\n options: {\n modules: {\n auto: /\\.custom-module\\.\\w+$/i,\n },\n },\n },\n ],\n },\n};\n```\n\n###### `function`\n\nEnable CSS modules for files based on the filename, query or fragment satisfying your filter function check.\n\n**webpack.config.js**\n\n```js\nmodule.exports = {\n module: {\n rules: [\n {\n test: /\\.css$/i,\n loader: \"css-loader\",\n options: {\n modules: {\n auto: (resourcePath, resourceQuery, resourceFragment) => {\n return resourcePath.endsWith(\".custom-module.css\");\n },\n },\n },\n },\n ],\n },\n};\n```\n\n##### `mode`\n\nType:\n\n```ts\ntype mode =\n | \"local\"\n | \"global\"\n | \"pure\"\n | \"icss\"\n | ((\n resourcePath: string,\n resourceQuery: string,\n resourceFragment: string\n ) => \"local\" | \"global\" | \"pure\" | \"icss\");\n```\n\nDefault: `'local'`\n\nSetup `mode` option. You can omit the value when you want `local` mode.\n\nControls the level of compilation applied to the input styles.\n\nThe `local`, `global`, and `pure` handles `class` and `id` scoping and `@value` values.\nThe `icss` will only compile the low level `Interoperable CSS` format for declaring `:import` and `:export` dependencies between CSS and other languages.\n\nICSS underpins CSS Module support, and provides a low level syntax for other tools to implement CSS-module variations of their own.\n\n###### `string`\n\nPossible values - `local`, `global`, `pure`, and `icss`.\n\n**webpack.config.js**\n\n```js\nmodule.exports = {\n module: {\n rules: [\n {\n test: /\\.css$/i,\n loader: \"css-loader\",\n options: {\n modules: {\n mode: \"global\",\n },\n },\n },\n ],\n },\n};\n```\n\n###### `function`\n\nAllows set different values for the `mode` option based on the filename, query or fragment.\n\nPossible return values -

from your bundle being able to use parallel loading of CSS/JS resources later on.\nThis can be achieved by using the [mini-css-extract-plugin](https://github.com/webpack-contrib/mini-css-extract-plugin), because it creates separate css files.\nFor `development` mode (including `webpack-dev-server`) you can use [style-loader](https://github.com/webpack-contrib/style-loader), because it injects CSS into the DOM using multiple `` and works faster.\n\n> **Note**\n>\n> Do not use `style-loader` and `mini-css-extract-plugin` together.\n\n**webpack.config.js**\n\n```js\nconst MiniCssExtractPlugin = require(\"mini-css-extract-plugin\");\nconst devMode = process.env.NODE_ENV !== \"production\";\n\nmodule.exports = {\n module: {\n rules: [\n {\n // If you enable `experiments.css` or `experiments.futureDefaults`, please uncomment line below\n // type: \"javascript/auto\",\n test: /\\.(sa|sc|c)ss$/i,\n use: [\n devMode ? \"style-loader\" : MiniCssExtractPlugin.loader,\n \"css-loader\",\n \"postcss-loader\",\n \"sass-loader\",\n ],\n },\n ],\n },\n plugins: [].concat(devMode ?

[extract-css-chunks-webpack-plugin](https://github.com/faceyspacey/extract-css-chunks-webpack-plugin) offers a hot module reload friendly, extended version of mini-css-extract-plugin. HMR real CSS files in dev, works like mini-css in non-dev\n\n### Pure CSS, CSS modules and PostCSS\n\nWhen you have pure CSS (without CSS modules), CSS modules and PostCSS in your project you can use this setup:\n\n**webpack.config.js**\n\n```js\nmodule.exports = {\n module: {\n rules: [\n {\n // For pure CSS - /\\.css$/i,\n // For Sass/SCSS - /\\.((c|sa|sc)ss)$/i,\n // For Less - /\\.((c|le)ss)$/i,\n test: /\\.((c|sa|sc)ss)$/i,\n use: [\n \"style-loader\",\n {\n loader: \"css-loader\",\n options: {\n // Run `postcss-loader` on each CSS `@import` and CSS modules/ICSS imports, do not forget that `sass-loader` compile non CSS `@import`'s into a single file\n // If you need run `sass-loader` and `postcss-loader` on each CSS `@import` please set it to `2`\n importLoaders: 1,\n },\n },\n {\n loader: \"postcss-loader\",\n options: { plugins: () => [postcssPresetEnv({ stage: 0 })] },\n },\n // Can be `less-loader`\n {\n loader: \"sass-loader\",\n },\n ],\n },\n // For webpack v5\n {\n test: /\\.(png|jpe?g|gif|svg|eot|ttf|woff|woff2)$/i,\n // More information here https://webpack.js.org/guides/asset-modules/\n type: \"asset\",\n },\n ],\n },\n};\n```\n\n### Resolve unresolved URLs using an alias\n\n**index.css**\n\n```css\n.class {\n background: url(/assets/unresolved/img.png);\n}\n```\n\n**webpack.config.js**\n\n```js\nmodule.exports = {\n module: {\n rules: [\n {\n test: /\\.css$/i,\n use: [\"style-loader\", \"css-loader\"],\n },\n ],\n },\n resolve: {\n alias: {\n \"/assets/unresolved/img.png\": path.resolve(\n __dirname,\n \"assets/real-path-to-img/img.png\"\n ),\n },\n },\n};\n```\n\n### Named export with custom export names\n\n**webpack.config.js**\n\n```js\nmodule.exports = {\n module: {\n rules: [\n {\n test: /\\.css$/i,\n loader: \"css-loader\",\n options: {\n modules: {\n namedExport: true,\n exportLocalsConvention: function (name) {\n return name.replace(/-/g, \"_\");\n },\n },\n },\n },\n ],\n },\n};\n```\n\n### Separating `Interoperable CSS`-only and `CSS Module` features\n\nThe following setup is an example of allowing `Interoperable CSS` features only (such as `:import` and `:export`) without using further `CSS Module` functionality by setting `mode` option for all files that do not match `*.module.scss` naming convention. This is for reference as having `ICSS` features applied to all files was default `css-loader` behavior before v4.\nMeanwhile all files matching `*.module.scss` are treated as `CSS Modules` in this example.\n\nAn example case is assumed where a project requires canvas drawing variables to be synchronized with CSS - canvas drawing uses the same color (set by color name in JavaScript) as HTML background (set by class name in CSS).\n\n**webpack.config.js**\n\n```js\nmodule.exports = {\n module: {\n rules: [\n // ...\n // --------\n // SCSS ALL EXCEPT MODULES\n {\n test: /\\.scss$/i,\n exclude: /\\.module\\.scss$/i,\n use: [\n {\n loader: \"style-loader\",\n },\n {\n loader: \"css-loader\",\n options: {\n importLoaders: 1,\n modules: {\n mode: \"icss\",\n },\n },\n },\n {\n loader: \"sass-loader\",\n },\n ],\n },\n // --------\n // SCSS MODULES\n {\n test: /\\.module\\.scss$/i,\n use: [\n {\n loader: \"style-loader\",\n },\n {\n loader: \"css-loader\",\n options: {\n importLoaders: 1,\n modules: {\n mode: \"local\",\n },\n },\n },\n {\n loader: \"sass-loader\",\n },\n ],\n },\n // --------\n // ...\n ],\n },\n};\n```\n\n**variables.scss**\n\nFile treated as `ICSS`-only.\n\n```scss\n$colorBackground: red;\n:export {\n colorBackgroundCanvas: $colorBackground;\n}\n```\n\n**Component.module.scss**\n\nFile treated as `CSS Module`.\n\n```scss\n@import \"variables.scss\";\n.componentClass {\n background-color: $colorBackground;\n}\n```\n\n**Component.jsx**\n\nUsing both `CSS Module` functionality as well as SCSS variables directly in JavaScript.\n\n```jsx\nimport svars from \"variables.scss\";\nimport styles from \"Component.module.scss\";\n\n// Render DOM with CSS modules class name\n//
\n// \n//
\n\n// Somewhere in JavaScript canvas drawing code use the variable directly\n// const ctx = mountsCanvas.current.getContext('2d',{alpha: false});\nctx.fillStyle = `${svars.colorBackgroundCanvas}`;\n```\n\n## Contributing\n\nPlease take a moment to read our contributing guidelines if you haven't yet done so.\n\n[CONTRIBUTING](./.github/CONTRIBUTING.md)\n\n## License\n\n[MIT](./LICENSE)\n\n[npm]: https://img.shields.io/npm/v/css-loader.svg\n[npm-url]: https://npmjs.com/package/css-loader\n[node]: https://img.shields.io/node/v/css-loader.svg\n[node-url]: https://nodejs.org\n[tests]: https://github.com/webpack-contrib/css-loader/workflows/css-loader/badge.svg\n[tests-url]: https://github.com/webpack-contrib/css-loader/actions\n[cover]: https://codecov.io/gh/webpack-contrib/css-loader/branch/master/graph/badge.svg\n[cover-url]: https://codecov.io/gh/webpack-contrib/css-loader\n[discussion]: https://img.shields.io/github/discussions/webpack/webpack\n[discussion-url]: https://github.com/webpack/webpack/discussions\n[size]: https://packagephobia.now.sh/badge?p=css-loader\n[size-url]: https://packagephobia.now.sh/result?p=css-loader\n", "licenseText": "Copyright JS Foundation and other contributors\n\nPermission is hereby granted, free of charge, to any person obtaining\na copy of this software and associated documentation files (the\n'Software'), to deal in the Software without restriction, including\nwithout limitation the rights to use, copy, modify, merge, publish,\ndistribute, sublicense, and/or sell copies of the Software, and to\npermit persons to whom the Software is furnished to do so, subject to\nthe following conditions:\n\nThe above copyright notice and this permission notice shall be\nincluded in all copies or substantial portions of the Software.\n\nTHE SOFTWARE IS PROVIDED 'AS IS', WITHOUT WARRANTY OF ANY KIND,\nEXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF\nMERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.\nIN NO EVENT SHALL THE AUTHORS OR COPYRIGHT HOLDERS BE LIABLE FOR ANY\nCLAIM, DAMAGES OR OTHER LIABILITY, WHETHER IN AN ACTION OF CONTRACT,\nTORT OR OTHERWISE, ARISING FROM, OUT OF OR IN CONNECTION WITH THE\nSOFTWARE OR THE USE OR OTHER DEALINGS IN THE SOFTWARE.\n" }, "artifacts": [], "remote": { "resolved": "https://registry.yarnpkg.com/css-loader/-/css-loader-6.11.0.tgz#33bae3bf6363d0a7c2cf9031c96c744ff54d85ba", "type": "tarball", "reference": "https://registry.yarnpkg.com/css-loader/-/css-loader-6.11.0.tgz", "hash": "33bae3bf6363d0a7c2cf9031c96c744ff54d85ba", "integrity": "sha512-CTJ+AEQJjq5NzLga5pE39qdiSV56F8ywCIsqNIRF0r7BDgWsN25aazToqAFg7ZrtA/U016xudB3ffgweORxX7g==", "registry": "npm", "packageName": "css-loader", "cacheIntegrity": "sha512-CTJ+AEQJjq5NzLga5pE39qdiSV56F8ywCIsqNIRF0r7BDgWsN25aazToqAFg7ZrtA/U016xudB3ffgweORxX7g== sha1-M7rjv2Nj0KfCz5AxyWx0T/VNhbo=" }, "registry": "npm", "hash": "33bae3bf6363d0a7c2cf9031c96c744ff54d85ba" }
