vscode配置eslint

背景

公司开始了新项目用了vue,因为用了某人开源的基础架构,所以被动的被用上了eslint,刚开始用sublime写vue,结果各种规法错误,很是恼火。最后按网上教程用了vscode+eslint插件,一键格式化错误,牛X死了

安装eslint插件

安装并配置完成 ESLint 后,我们继续回到 VSCode 进行扩展设置,依次点击 文件 > 首选项 > 设置 打开 VSCode 配置文件,添加如下配置

"eslint.autoFixOnSave": true,
"files.autoSave":"off",
"eslint.validate": [
"javascript",
"javascriptreact",
"html",
{ "language": "vue", "autoFix": true }
],
"eslint.options": {
"plugins": ["html"]
}

这样每次保存的时候就可以根据根目录下.eslintrc.js你配置的eslint规则来检查和做一些简单的fix。
