vscode eslint 自动保存

vscode安装插件Prettier - JavaScript formatter和vetur

File -> Preference -> Settings（如果装了中文插件包应该是 文件 -> 选项 -> 用户），搜索 eslint，点击 Edit in setting.json

最新版本只需添加

{
"editor.codeActionsOnSave": {
        "source.fixAll.eslint": true,
    },

}

添加后 ，Ctrl+s保存会自动按照你的项目建的eslintrc.js文件的规则修复

我的eslintrc.js内容：

module.exports = {
    settings: {
        "import/resolver": {
            webpack: {
                config: './build/webpack.base.conf.js'
            }
        }
    },
