vscode alias 代码提示

vue 配置了 alias，如:

chainWebpack: config => {
  config.resolve.alias.set('vue$', 'vue/dist/vue.esm.js')
  config.resolve.alias.set('@img', path.resolve(__dirname, 'src/assets/images'))
  config.resolve.alias.set('@js', path.resolve(__dirname, 'src/assets/js'))
  ...
}

这样在 import XXX from "@js/xxx" 后，没有代码提示了

在根目录新建 jsconfig.json，内容:

{
	"compilerOptions": {
		"baseUrl": "./",
		"paths": {
			"@img/*": ["src/assets/images/*"],
			"@js/*": ["src/assets/js/*"],
      ...
		}
	},
	"exclude": ["node_modules", "dist"]
}

用于配置 alias 指向的目录，然后 重启 vscode!
