好玩的代码快捷片段，开发时输入以下字符串会有自动代码片段完成：

• istanbul
• eslint
• ipt: import
• MyError

好像有midway自带的代码提示呢。

好像有midway自带的代码提示呢。

相当于是利用 VSCode 的自动提示功能实现代码片段的输出

比如输入 ipt.myerror ，VSCode 就会自动在光标当前位置输出以下代码

import MyError from '@/app/util/my-error'

之前老是记不住 istanbul 代码覆盖忽略行的语法，现在输入 cov else 然后选择自动提示的 cov.ignore-else 就能自动填充以下代码

/* istanbul ignore else */

这个加到wiki作为推荐吧
