使用craco修改react项目

安装craco
yarn add @craco/craco

---

替换package.json

 ...
 "scripts": {
    "start": "craco start",
    "build": "craco build",
    "test": "craco test",
    "eject": "react-scripts eject"
  },
 ...

---

可以额外配置
在根目录创建craco.config.js文件

const path = require("path")

const resolve = dir => path.resolve(__dirname, dir);

module.exports = {
    webpack: {
        alias: {
            //使用@替换src
            '@': resolve("src"),
            //components替换src/components
            'components': resolve("src/components")
        }
    }
}
