Using Taobao NPM Mirror
Everyone knows that it is very slow to directly use the official npm mirror in China. It is recommended to use Taobao NPM mirror here.
Taobao NPM mirror is a complete npmjs.org mirror, you can use this instead of the official version (read-only). The synchronization frequency is currently every 10 minutes to ensure that it is synchronized with the official service as much as possible.
You can use Taobao's customized cnpm (gzip compression support) command line tool instead of the default npm:
$ npm install -g cnpm --registry=https://registry.npm.taobao.org
Then you can use the cnpm command to install modules now:
$ cnpm install [name]
