介绍
eslint-config-blued-react 是 Blued React 项目中使用的 eslint 配置文件，使用它可以大大提高我们的代码规范和代码质量。本篇文章将详细介绍 eslint-config-blued-react 的使用方法和配置细节。
安装
首先，我们需要在项目中安装 eslint 和 eslint-config-blued-react：
npm install eslint eslint-config-blued-react --save-dev
配置
在项目中的 .eslintrc 文件中，我们需要做以下配置：
{
"extends": [
"eslint-config-blued-react"
],
"rules": {
// 此处配置规则覆盖
}
}这段配置表示我们的 eslint 规则继承自 eslint-config-blued-react，同时可以在 rules 中添加新的规则或覆盖原有的规则。
使用
在我们的项目中，我们可以通过运行 eslint 命令来检查我们的代码是否符合 eslint-config-blued-react 的规范：
eslint src
这里的 src 是我们项目的源代码目录。
如果希望自动修复 eslint 检测出的错误，可以加上 --fix 参数：
eslint src --fix
