# 2.1.3 安装

## Server(服务端)

```
npm install --save socket.io
```

[源码](https://github.com/socketio/socket.io)

## Javascript(客户端)

服务器默认情况下会在`/socket.io/socket.io.js`中暴露客户端的独立版本，（其实client集成在socket.io里面的一个客户端版本）

也可以在 CDN 中引入，[请戳](https://cdnjs.com/libraries/socket.io)

在`Node.js`中，或者在打包工具比如 `webpack` 或者 `browserify`，你也可以从`npm`中安装依赖包：

```
npm install --save socket.io-client
```

[源码](https://github.com/socketio/socket.io-client)
