vscode 配置import @ 路径提示及代码智提

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"
    ]
}
