为了保证多个项目复用代码，我喜欢把路径别名设置为@，下面介绍vscode中的配置方法。

1、安装插件Path Intellisense

2、配置

"path-intellisense.mappings": {"@": "${workspaceRoot}/src"
}

3、在项目package.json所在同级目录下创建文件jsconfig.json：

{"compilerOptions": {"target": "ES6","module": "commonjs","allowSyntheticDefaultImports": true,"baseUrl": "./","paths": {"@/*": ["src/*"]}},"exclude": ["node_modules"]
}

备注：我在nuxt项目中会这样配置

{"compilerOptions": {"target": "ES6","module": "commonjs","allowSyntheticDefaultImports": true,"baseUrl": "./","paths": {"@/*": ["*"]}},"exclude": ["node_modules"]
}
