# 10. 分离css插件

以css配置示例,less与sass同理

## 1. 使用旧版的ExtractTextPlugin插件

### 安装

```
npm install extract-text-webpack-plugin@next --save-dev
```

### 在webpack.config.js中配置

```javascript
const extractTextPlugin=require('extract-text-webpack-plugin')

module.exports={
    //...code
    module:{
       rules:[{
            test:/\.css$/,
            use:extractTextPlugin.extract({
                fallback:"style-loader",
                use:['css-loader'],
                publicPath:"../"
            })
        }]
    },
    plugins:[
        new extractTextPlugin("./css/[name].css")//输出路径
    ]
}
```

如果还使用了根据css自动加前缀loader

```javascript
const extractTextPlugin=require('extract-text-webpack-plugin')

module.exports={
    //...code
    module:{
       rules:[{
            test:/\.css$/,
            use:extractTextPlugin.extract({
                fallback: "style-loader",
                use: ['css-loader', {
                        loader: 'postcss-loader',
                        options: {
                            plugins: [require('autoprefixer')]
                        }
                    }]
                publicPath: '../'
            })
        }]
    },
    plugins:[
        new extractTextPlugin("./css/[name].css")//输出路径
    ]
}
```

### 使用方法

配置完成后运行webpack打包即可

## 2.使用新版mini-css-extract-plugin 插件

### 安装

```
npm install mini-css-extract-plugin --save-dev
```

### 在webpack.config.js中配置

```javascript
const miniCssPlugin=require('mini-css-extract-plugin');
module.exports={
    module:{
        rules:[
            {
                test:/\.css$/,
                use: [{
                    loader: miniCssPlugin.loader,
                    options: {
                        publicPath: '../'
                    }
                }, 'css-loader']
            }
        ]
    },
    plugins:[
        new miniCssPlugin({
            filename:'./css/[name].css'
        })
    ]
}
```

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://sugar-at.gitbook.io/blog-article/webpack/css-extract.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
