React项目创建使用react-app-rewired customize-cra进行配置

//项目创建
npx create-react-app projectname

1 yarn add react-app-rewired customize-cra
2 在项目根目录下创建一个config-overrides.js

修改package.json:

    "scripts": {
        - "start": "react-scripts start",
        + "start": "react-app-rewired start",
        - "build": "react-scripts build",
        + "build": "react-app-rewired build",
        - "test": "react-scripts test",
        + "test": "react-app-rewired test",
    }

config-overrides.js：

 // @符号
const path = require("path");
const {
    override,
    addWebpackAlias
} = require("customize-cra");
//按需加载组件
module.exports = override(
    addWebpackAlias({
        ["@"]: path.resolve(__dirname, "src")
    }),
);
