+
+> [PostCSS](https://github.com/postcss/postcss) plugin to transform `@import`
+rules by inlining content.
+
+This plugin can consume local files, node modules or web_modules.
+To resolve path of an `@import` rule, it can look into root directory
+(by default `process.cwd()`), `web_modules`, `node_modules`
+or local modules.
+_When importing a module, it will look for `index.css` or file referenced in
+`package.json` in the `style` or `main` fields._
+You can also provide manually multiples paths where to look at.
+
+**Notes:**
+
+- **This plugin should probably be used as the first plugin of your list.
+This way, other plugins will work on the AST as if there were only a single file
+to process, and will probably work as you can expect**.
+- This plugin works great with
+[postcss-url](https://github.com/postcss/postcss-url) plugin,
+which will allow you to adjust assets `url()` (or even inline them) after
+inlining imported files.
+- In order to optimize output, **this plugin will only import a file once** on
+a given scope (root, media query...).
+Tests are made from the path & the content of imported files (using a hash
+table).
+If this behavior is not what you want, look at `skipDuplicates` option
+- If you are looking for **Glob Imports**, you can use [postcss-import-ext-glob](https://github.com/dimitrinicolas/postcss-import-ext-glob) to extend postcss-import.
+- Imports which are not modified (by `options.filter` or because they are remote
+  imports) are moved to the top of the output.
+- **This plugin attempts to follow the CSS `@import` spec**; `@import`
+  statements must precede all other statements (besides `@charset`).
+
+## Installation
+
+```console
+$ npm install -D postcss-import
+```
+
+## Usage
+
+Unless your stylesheet is in the same place where you run postcss
+(`process.cwd()`), you will need to use `from` option to make relative imports
+work.
+
+```js
+// dependencies
+const fs = require("fs")
+const postcss = require("postcss")
+const atImport = require("postcss-import")
+
+// css to be processed
+const css = fs.readFileSync("css/input.css", "utf8")
+
+// process css
+postcss()
+  .use(atImport())
+  .process(css, {
+    // `from` option is needed here
+    from: "css/input.css"
+  })
+  .then((result) => {
+    const output = result.css
+
+    console.log(output)
+  })
+```
+
+`css/input.css`:
+
+```css
+/* can consume `node_modules`, `web_modules` or local modules */
+@import "cssrecipes-defaults"; /* == @import "../node_modules/cssrecipes-defaults/index.css"; */
+@import "normalize.css"; /* == @import "../node_modules/normalize.css/normalize.css"; */
+
+@import "foo.css"; /* relative to css/ according to `from` option above */
+
+@import "bar.css" (min-width: 25em);
+
+@import 'baz.css' layer(baz-layer);
+
+body {
+  background: black;
+}
+```
+
+will give you:
+
+```css
+/* ... content of ../node_modules/cssrecipes-defaults/index.css */
+/* ... content of ../node_modules/normalize.css/normalize.css */
+
+/* ... content of css/foo.css */
+
+@media (min-width: 25em) {
+/* ... content of css/bar.css */
+}
+
+@layer baz-layer {
+/* ... content of css/baz.css */
+}
+
+body {
+  background: black;
+}
+```
+
+Checkout the [tests](test) for more examples.
+
+### Options
+
+### `filter`
+Type: `Function`  
+Default: `() => true`
+
+Only transform imports for which the test function returns `true`. Imports for
+which the test function returns `false` will be left as is. The function gets
+the path to import as an argument and should return a boolean.
+
+#### `root`
+
+Type: `String`  
+Default: `process.cwd()` or _dirname of
+[the postcss `from`](https://github.com/postcss/postcss#node-source)_
+
+Define the root where to resolve path (eg: place where `node_modules` are).
+Should not be used that much.  
+_Note: nested `@import` will additionally benefit of the relative dirname of
+imported files._
+
+#### `path`
+
+Type: `String|Array`  
+Default: `[]`
+
+A string or an array of paths in where to look for files.
+
+#### `plugins`
+
+Type: `Array`  
+Default: `undefined`
+
+An array of plugins to be applied on each imported files.
+
+#### `resolve`
+
+Type: `Function`  
+Default: `null`
+
+You can provide a custom path resolver with this option. This function gets
+`(id, basedir, importOptions)` arguments and should return a path, an array of
+paths or a promise resolving to the path(s). If you do not return an absolute
+path, your path will be resolved to an absolute path using the default
+resolver.
+You can use [resolve](https://github.com/substack/node-resolve) for this.
+
+#### `load`
+
+Type: `Function`  
+Default: null
+
+You can overwrite the default loading way by setting this option.
+This function gets `(filename, importOptions)` arguments and returns content or
+promised content.
+
+#### `skipDuplicates`
+
+Type: `Boolean`  
+Default: `true`
+
+By default, similar files (based on the same content) are being skipped.
+It's to optimize output and skip similar files like `normalize.css` for example.
+If this behavior is not what you want, just set this option to `false` to
+disable it.
+
+#### `addModulesDirectories`
+
+Type: `Array`  
+Default: `[]`
+
+An array of folder names to add to [Node's resolver](https://github.com/substack/node-resolve).
+Values will be appended to the default resolve directories:
+`["node_modules", "web_modules"]`.
+
+This option is only for adding additional directories to default resolver. If
+you provide your own resolver via the `resolve` configuration option above, then
+this value will be ignored.
+
+#### `nameLayer`
+
+Type: `Function`
+Default: `null`
+
+You can provide a custom naming function for anonymous layers (`@import 'baz.css' layer;`).
+This function gets `(index, rootFilename)` arguments and should return a unique string.
+
+This option only influences imports without a layer name.
+Without this option the plugin will warn on anonymous layers.
+
+#### Example with some options
+
+```js
+const postcss = require("postcss")
+const atImport = require("postcss-import")
+
+postcss()
+  .use(atImport({
+    path: ["src/css"],
+  }))
+  .process(cssString)
+  .then((result) => {
+    const { css } = result
+  })
+```
+
+## `dependency` Message Support
+
+`postcss-import` adds a message to `result.messages` for each `@import`. Messages are in the following format:
+
+```
+{
+  type: 'dependency',
+  file: absoluteFilePath,
+  parent: fileContainingTheImport
+}
+```
+
+This is mainly for use by postcss runners that implement file watching.

+# example
+
+asynchronously resolve:
+
+```js
+var resolve = require('resolve/async'); // or, require('resolve')
+resolve('tap', { basedir: __dirname }, function (err, res) {
+    if (err) console.error(err);
+    else console.log(res);
+});
+```
+
+```
+$ node example/async.js
+/home/substack/projects/node-resolve/node_modules/tap/lib/main.js
+```
+
+synchronously resolve:
+
+```js
+var resolve = require('resolve/sync'); // or, `require('resolve').sync
+var res = resolve('tap', { basedir: __dirname });
+console.log(res);
+```
+
+```
+$ node example/sync.js
+/home/substack/projects/node-resolve/node_modules/tap/lib/main.js
+```
+
+# methods
+
+```js
+var resolve = require('resolve');
+var async = require('resolve/async');
+var sync = require('resolve/sync');
+```
+
+For both the synchronous and asynchronous methods, errors may have any of the following `err.code` values:
+
+- `MODULE_NOT_FOUND`: the given path string (`id`) could not be resolved to a module
+- `INVALID_BASEDIR`: the specified `opts.basedir` doesn't exist, or is not a directory
+- `INVALID_PACKAGE_MAIN`: a `package.json` was encountered with an invalid `main` property (eg. not a string)
+
+## resolve(id, opts={}, cb)
+
+Asynchronously resolve the module path string `id` into `cb(err, res [, pkg])`, where `pkg` (if defined) is the data from `package.json`.
+
+options are:
+
+* opts.basedir - directory to begin resolving from
+
+* opts.package - `package.json` data applicable to the module being loaded
+
+* opts.extensions - array of file extensions to search in order
+
+* opts.includeCoreModules - set to `false` to exclude node core modules (e.g. `fs`) from the search
+
+* opts.readFile - how to read files asynchronously
+
+* opts.isFile - function to asynchronously test whether a file exists
+
+* opts.isDirectory - function to asynchronously test whether a file exists and is a directory
+
+* opts.realpath - function to asynchronously resolve a potential symlink to its real path
+
+* `opts.readPackage(readFile, pkgfile, cb)` - function to asynchronously read and parse a package.json file
+  * readFile - the passed `opts.readFile` or `fs.readFile` if not specified
+  * pkgfile - path to package.json
+  * cb - callback
+
+* `opts.packageFilter(pkg, pkgfile, dir)` - transform the parsed package.json contents before looking at the "main" field
+  * pkg - package data
+  * pkgfile - path to package.json
+  * dir - directory that contains package.json
+
+* `opts.pathFilter(pkg, path, relativePath)` - transform a path within a package
+  * pkg - package data
+  * path - the path being resolved
+  * relativePath - the path relative from the package.json location
+  * returns - a relative path that will be joined from the package.json location
+
+* opts.paths - require.paths array to use if nothing is found on the normal `node_modules` recursive walk (probably don't use this)
+
+  For advanced users, `paths` can also be a `opts.paths(request, start, opts)` function
+    * request - the import specifier being resolved
+    * start - lookup path
+    * getNodeModulesDirs - a thunk (no-argument function) that returns the paths using standard `node_modules` resolution
+    * opts - the resolution options
+
+* `opts.packageIterator(request, start, opts)` - return the list of candidate paths where the packages sources may be found (probably don't use this)
+    * request - the import specifier being resolved
+    * start - lookup path
+    * getPackageCandidates - a thunk (no-argument function) that returns the paths using standard `node_modules` resolution
+    * opts - the resolution options
+
+* opts.moduleDirectory - directory (or directories) in which to recursively look for modules. default: `"node_modules"`
+
+* opts.preserveSymlinks - if true, doesn't resolve `basedir` to real path before resolving.
+This is the way Node resolves dependencies when executed with the [--preserve-symlinks](https://nodejs.org/api/all.html#cli_preserve_symlinks) flag.
+**Note:** this property is currently `true` by default but it will be changed to
+`false` in the next major version because *Node's resolution algorithm does not preserve symlinks by default*.

+
+* `opts.packageFilter(pkg, dir)` - transform the parsed package.json contents before looking at the "main" field
