用webpack-dev-server開發時代理，決解開發時跨域問題

需要webpack，webpack-dev-server

npm install webapck webpack-dev-server --save-dev

設置時

devServer: {
        historyApiFallback: true,
          hot: true,
        inline: true,
        stats: { colors: true },
        proxy: {
            '/list': {
              target: 'https://api.github.com',
              pathRewrite: {'^/column' : '/column'},
              changeOrigin: true
            }
         }
    },

這段代碼就是將  '/list' 通過本地開發服務器webpack-dev-server轉發到 'https://api.github.com'
