React Webpack copy文件到build路径

目的：webpack打包时将资源文件copy到指定路径

1：安装依赖copy-webpack-plugin、customize-cra、react-app-rewired

2：修改script，使用react-app-rewired命令

"build:copy": "cross-env NODE_ENV=production GENERATE_SOURCEMAP=false react-app-rewired --max-old-space-size=8192 build",

3：配置config-overrides.js

const { override, fixBabelImports } = require('customize-cra');
const CopyWebpackPlugin = require('copy-webpack-plugin');

const copyFileConfig= ()=>(config, env)=>{
	config.plugins.push(
		new CopyWebpackPlugin(
		[
		  {
			from: 'assets/sample.csv',
			to: 'assets/sample.csv'
		  }
		])
	  );
	
    return config;
}

module.exports = override(
copyFileConfig(),
//这里是antd的示例，与本主题无关
fixBabelImports('import', {
		libraryName: 'antd',
		libraryDirectory: 'es',
		style: 'css',
	}),
);

4：打包时执行npm run build:copy即可
