  <h1>Style Resources Loader</h1>
  <p>CSS processor resources loader for webpack.</p>
</div>


<h2 align="center">Install</h2>

```bash
npm i style-resources-loader -D
```

<h2 align="center">Usage</h2>

This loader is a CSS processor resources loader for webpack, which injects your style resources (e.g. `variables, mixins`) into multiple imported `css, sass, scss, less, stylus` modules.

It's mainly used to
 - share your `variables, mixins, functions` across all style files, so you don't need to `@import` them manually.
 - override `variables` in style files provided by other libraries (e.g. [ant-design](https://github.com/ant-design/ant-design)) and customize your own theme.

### Usage with Vue CLI

See [automatic imports](https://cli.vuejs.org/guide/css.html#automatic-imports) for more details.

<h2 align="center">Examples</h2>

Prepends `variables` and `mixins` to all `scss` files with default resources injector.

**webpack.config.js**
``` js
module.exports = {
    // ...
    module: {
        rules: [{
            test: /\.scss$/,
            use: ['style-loader', 'css-loader', 'sass-loader', {
                loader: 'style-resources-loader',
                options: {
                    patterns: [
                        './path/from/context/to/scss/variables/*.scss',
                        './path/from/context/to/scss/mixins/*.scss',
                    ]
                }
            }]
        }]
    },
    // ...
}
```

Appends `variables` to all `less` files and overrides original `less variables`.

**webpack.config.js**
```js
module.exports = {
    // ...
    module: {
        rules: [{
            test: /\.less$/,
            use: ['style-loader', 'css-loader', 'less-loader', {
                loader: 'style-resources-loader',
                options: {
                    patterns: path.resolve(__dirname, 'path/to/less/variables/*.less'),
                    injector: 'append'
                }
            }]
        }]
    },
    // ...
}
```

Prepends `variables` and `mixins` to all `stylus` files with customized resources injector.

**webpack.config.js**
``` js
module.exports = {
    // ...
    module: {
        rules: [{
            test: /\.styl$/,
            use: ['style-loader', 'css-loader', 'stylus-loader', {
                loader: 'style-resources-loader',
                options: {
                    patterns: [
                        path.resolve(__dirname, 'path/to/stylus/variables/*.styl'),
                        path.resolve(__dirname, 'path/to/stylus/mixins/*.styl')
                    ],
                    injector: (source, resources) => {
                        const combineAll = type => resources
                            .filter(({ file }) => file.includes(type))
                            .map(({ content }) => content)
                            .join('');

                        return combineAll('variables') + combineAll('mixins') + source;
                    }
                }
            }]
        }]
    },
    // ...
}
```

<h2 align="center">Options</h2>

|Name|Type|Default|Description|
|:--:|:--:|:-----:|:----------|
|**[`patterns`](#patterns)**|`string \| string[]`|`/`|Path to the resources you would like to inject|
|**[`injector`](#injector)**|`Injector \| 'prepend' \| 'append'`|`'prepend'`|Controls the resources injection precisely|
|**[`globOptions`](#globoptions)**|`GlobOptions`|`{}`|An options that can be passed to `glob(...)`|
|**[`resolveUrl`](#resolveurl)**|`boolean`|`true`|Enable/Disable `@import` url to be resolved|

See [the type definition file](https://github.com/yenshih/style-resources-loader/blob/master/src/types.ts) for more details.

### `patterns`

A string or an array of string, which represents the path to the resources you would like to inject. If the path is relative, it would relative to [webpack context](https://webpack.js.org/configuration/entry-context/).

It supports [globbing](https://github.com/isaacs/node-glob). You could include many files using a file mask.

For example, `'./styles/*/*.less'` would include all `less` files from `variables` and `mixins` directories and ignore `reset.less` in such following structure.

```
./src  <-- webpack context
  /styles
    /variables
      |-- fonts.less
      |-- colors.less
    /mixins
      |-- size.less
    |-- reset.less
```

Only supports `.css` `.sass` `.scss` `.less` `.styl` as resources file extensions.

### `injector`

An optional function which controls the resources injection precisely. It also supports `'prepend'` and `'append'` for convenience, which means the loader will prepend or append all resources to source files, respectively.

It defaults to `'prepend'`, which implements as an injector function internally.

Furthermore, an injector function should match the following type signature:

```ts
type Injector = (
    this: LoaderContext,
    source: string,
    resources: StyleResource[],
) => string | Promise<string>
```

It receives two parameters:

|Name|Type|Description|
|:--:|:--:|:----------|
|**`source`**|`string`|Content of the source file|
|**[`resources`](#resources)**|`StyleResource[]`|Resource descriptors|

It is called with `this` context pointing to the loader context.

#### `resources`

An array of resource descriptor, each contains `file` and `content` properties:

|Name|Type|Description|
|:--:|:--:|:----------|
|**`file`**|`string`|Absolute path to the resource|
|**`content`**|`string`|Content of the resource file|

It can be asynchronous. You could use `async / await` syntax in your own injector function or just return a promise.

### `globOptions`

Options that can be passed to `glob(...)`. See [node-glob options](https://github.com/isaacs/node-glob#options) for more details.

### `resolveUrl`

A boolean which defaults to `true`. It represents whether the relative path in `@import` or `@require` statements should be resolved.

If you were to use `@import` or `@require` statements in style resource files, you should make sure that the URL is relative to that resource file, rather than the source file.

You could disable this feature by setting `resolveUrl` to `false`.
