react解决同源策略的方案

以下是webpack.config.js的配置文件案例

const path = require('path');
//插件案例
const MonacoWebpackPlugin = require('monaco-editor-webpack-plugin');

function resolvePath(pathUnderSrc) {
  return path.resolve(__dirname, `src/${pathUser}/`);
}

module.exports = {
  resolve: {
  //别名
    alias: {
      ':types': resolvePath('types'),
    }
  },
  devServer: {
    // port: 9000,
	//同源策略
    headers: {
      'Access-Control-Allow-Origin': '*'
    }
  },
  plugins: [
    new MonacoWebpackPlugin({
      languages: ['javascript', 'json']
    })
  ]
};
