vscode中使用eslint格式化代码

在vscode的插件商店中下载eslint

eslint配置

配置初始化

在vscode中按F1调出命令行,打Create ESLint configuration,会出现交互式配置

说明:

*
commonjs是使用module.exports和require的规范;

*
semi是结尾分号

*
indent是缩进

*
JSX是js的拓展

关于vue的配置文件
module.exports = { root: true, parser: 'babel-eslint', parserOptions: {
sourceType:'module' }, env: { browser: true, node: true, es6: true, }, extends:
