发表于 分类于 阅读次数：

最近在使用js开发项目，用到了requirejs，到后面会发现好多的js文件要加载，于是找到了优化js的方法，就是使用requirejs自带的Optimizer优化器。

具体操作如下：

前提是你已经安装了nodejs：

0.安装requirejs

1
sudo cnpm install requirejs -g / cnpm install requirejs -g / npm install requirejs -g /sudo npm install requirejs -g

1.构建一个配置文件(相对于执行文件夹)并包含指定的参数，build.js

2.编写build.js，内容如下（仅供参考）：

        }
    ],

    map: {
        '*': {
            'css': 'vendor/require-css/css'
        }
    }
})

3.执行命令

1
r.js -o build.js
