今天手动更新，碰到这个错误： No module named _cffi_backend 不知何故，不过容易解决，重新装一箱cffi就可以了： For python2.x use following command: python -m pip install cffi for python3.x python3 -m pip install cffi

棒棒的！期待更多人加入！

设置cognito有点麻烦，这篇文章介绍的很好！ https://aws.amazon.com/blogs/aws/launch-amazon-cognito-user-pools-general-availability-app-integration-and-federation/

Easier way const groupBy = (items, key) => items.reduce( (result, item) => ({ ...result, [item[key]]: [ ...(result[item[key]] || []), item, ], }), {}, ); const pets = [ {type:"Dog", name:"Spot"}, {type:"Cat", name:"Tiger"}, {type:"Dog", name:"Rover"}, {type:"Cat", name:"Leo"} ]; const result = groupBy(pets, 'type'); console.log(result);

其實在next.config.js裡加env，這個值會在build的時候被用上。 const withPlugins = require("next-compose-plugins"); const css = require("@zeit/next-css"); // require("dotenv").config(); const nextConfig = { target: "serverless", webpack(config) { config.module.rules.push({ test: /\.(png|svg|eot|otf|ttf|woff|woff2)$/, use: { loader: "url-loader", options: { limit: 8192, publicPath: "/_next/static/", outputPath: "static/", name: "[name].[ext]" } } }); return config; }, env: { API_HOST: "http://www.localhost:3030" } // publicRuntimeConfig: { // // Will be available on both server and client // API_HOST: process.env.API_HOST // } }; module.exports = withPlugins([[css]], nextConfig); 這樣更好。 注意使用"now"來部署是serverless，所以用不了publicRuntimeConfig。
