AWS Amplify とは？
aws.amazon.com
モバイルアプリケーションやウェブアプリケーションを構築するための JavaScript フレームワークです。
これを使うことで、後述する AWS Cognito を簡単に使用できます。
AWS Cognito とは？
ユーザー管理を一括で行ってくれるユーザー認証サービスです。
Auth0 の AWS版といったところでしょうか。
この様に色々と設定できます。
Next.js とは？
React.js でサーバーサイドレンダリングするためのフレームワークです。
Vue.js の Nuxt.js のようなものですね。
やってみよう！
1. Next.js with TypeScript な環境を作る
https://nextjs.org のサイトの手順を参考に、TypeScript に対応した Next.js アプリが実行できる環境を構築します。
ちなみに、筆者はyarn を使うことが多いですが、公式ドキュメントは npm ベースです。npm を使われる方は適宜、置き換えてお読みください。

2. amplify の導入
オフィシャルドキュメント https://aws-amplify.github.io/docs/ のとおり、CLIインストールと設定を行います。
npm install -g @aws-amplify/cli
amplify configure
AWS 管理コンソールが起動して、使うリージョンだとか、amplify を管理するための(?) IAM ユーザーの作成などをターミナルに表示されたメッセージに従って行います。
3. アプリケーションへの適用
3.1. nom モジュールのインストール
amplify には色々な AWS サービスを使うための npm モジュールがあるようですが、今回は以下の 3つを使用します。
- aws-amplify
- @aws-amplify/auth
- aws-amplify-react
yarn add aws-amplify @aws-amplify/auth aws-amplify-react
3.2. amplify アプリの初期化
3.2.1. amplify init
amplify init
を実行すると、プロジェクト名や使用するエディター、環境名などの選択や入力を求められます。
指示に従って進めると、バックエンドコードが出力されます。
これは、後ほど amplify コマンドで使うことになる CloudFormation テンプレートや CloudFormation Stack などです。
$ amplify init
Note: It is recommended to run this command from the root of your app directory
? Enter a name for the project next-amplify-example
? Enter a name for the environment dev
? Choose your default editor: Visual Studio Code
? Choose the type of app that you're building javascript
Please tell us about your project
? What javascript framework are you using react
? Source Directory Path: src
? Distribution Directory Path: build
? Build Command: yarn build
? Start Command: yarn start
Using default provider awscloudformation
For more information on AWS Profiles, see:
https://docs.aws.amazon.com/cli/latest/userguide/cli-multiple-profiles.html
? Do you want to use an AWS profile? Yes
? Please choose the profile you want to use amplify

✔ Successfully created initial AWS cloud resources for deployments.
✔ Initialized provider successfully.
Initialized your environment successfully.
Your project has been successfully initialized and connected to the cloud!
Some next steps:
"amplify status" will show you what you've added already and if it's locally configured or deployed
"amplify add <category>" will allow you to add features like user login or a backend API
"amplify push" will build all your local backend resources and provision it in the cloud
“amplify console” to open the Amplify Console and view your project status
"amplify publish" will build all your local backend and frontend resources (if you have hosting category added) and provision it in the cloud
Pro tip:
Try "amplify add api" to create a backend API and then "amplify publish" to deploy everything

3.2.2. amplify add auth
amplify から Cognito を使用して認証するため、 amplify add auth を行います。
多分、Cognito 以外も使えそうですが、今回は Cognito を使うために追加するとお考えください。
amplify add auth
こんな感じです。今回はザルセキュリティで良い(あくまでもサンプルなので)ので、ユーザー名とパスワードでのみの認証とします。
(本来なら、メールアドレス他、色々と設定すべきでしょう)
$ amplify add auth
Using service: Cognito, provided by: awscloudformation
The current configured provider is Amazon Cognito.
Do you want to use the default authentication and security configuration? Default configuration
Warning: you will not be able to edit these selections.
How do you want users to be able to sign in? Username
Do you want to configure advanced settings? No, I am done.
Successfully added resource nextamplifyexample6c8f8585 locally
Some next steps:
"amplify push" will build all your local backend resources and provision it in the cloud
"amplify publish" will build all your local backend and frontend resources (if you have hosting category added) and provision it in the cloud
3.3. amplify バックグラウンド(AWS側のリソース)の構築
"amplify push" will build all your local backend resources and provision it in the cloud とあるように、AWS側のリソースを構築する必要があります。
amplify push
を実行すると、CloudFormation スタックが更新されて ネステッドスタックとなります。
また、Cognito のリソースが作られます。
$ amplify push

ここまでで、Cognito を呼び出す下地は出来ました。
あとは、アプリのコードから amplify を使って Cognito を呼び出すだけです！
3.4. アプリへの組み込み
React & React Native
に従って組み込んでみましょう！
因みに、今回は pages/index.tsx へ組み込みました。
Layout など、components 配下のコンポーネントを必ず組み込むようにする場合は、そちらに記述した方が良いかもしれません。
import Amplify from 'aws-amplify';
import config from '../aws-exports';
Amplify.configure(config);
class Home extends React.Component {
render() {
return (
<div>
// 以下略
続いて pages/_app.tsx
import * as React from 'react';
import App from 'next/app';
import { withAuthenticator } from 'aws-amplify-react';
class MyApp extends App {
render() {
const { Component, pageProps } = this.props;
return (<Component {...pageProps} />)
}
}
export default withAuthenticator(MyApp)
さぁ！これで yarn run dev すっぞ！

はい。。。コケました。
Next.js project fails to build, Unexpected token : at dist/style.css · Issue #3854 · aws-amplify/amplify-js · GitHub が原因のようですね。
@zeit/next-css を追加して、 next.config.js を修正すれば良いようです。
$ yarn add -D @zeit/next-css

さて、ここまでで Amplify と Cognitoを使用して、ローカルでサインイン出来るようになりました。
でも、サインアウト出来るようにしておかないとダメですよね？(滅多に使わないから期間過ぎたら自動的にサインアウトするように Cognito を設定しておけばよくね？というツッコミは無しで)

Authentication
に記載されている通り、 Auth モジュールの signOut() を呼び出せば良いだけですね。
import React from 'react'
import Amplify, { Auth } from 'aws-amplify';
import config from '../aws-exports';
import Button from '@material-ui/core/Button';
import ExitToAppIcon from '@material-ui/icons/ExitToApp';
Amplify.configure(config);
class Home extends React.Component {
logout() {
Auth.signOut()
.then(data => console.log(data))
.catch(err => console.log(err));
}
render() {
return (
<div>
<Button

>
SIGN OUT
</Button>
// (以下略)

出来ました！
ただ、 GitHub - poad/next-ts-template のブランチを元に作成した場合、next.config.js を次のように修正しないと、
aws-amplify-react の Global Stylesheet 関連の処理やら styled-jsx やらとの兼ね合いでコケました。(styled-jsx は結果的に使っていないので yarn remove しました)
因みに、 yarn run dev ではコケずに yarn build でだけコケるとかあったのでご注意を！
const withCSS = require('@zeit/next-css')
if (typeof require !== "undefined") {
require.extensions[".less"] = () => { };
require.extensions[".css"] = (file) => { };
}
const resolve = require('resolve')
global.navigator = () => null
const config = {
webpack(config, options) {
const { dir, isServer } = options
config.externals = []
if (isServer) {
config.externals.push((context, request, callback) => {
resolve(request, { basedir: dir, preserveSymlinks: true }, (err, res) => {
if (err) {
return callback()
}
if (
res.match(/node_modules[/\\].*\.css/)
&& !res.match(/node_modules[/\\]webpack/)
&& !res.match(/node_modules[/\\]@aws-amplify/)
) {
return callback(null, `css ${request}`)
}
callback()
})
})
}
return config
}
}
module.exports = withCSS(config)
と、なかなかハマりどころ多いですが、Nuxt.js(Vue.js) + TypeScript + amplify よりは簡単そうです。
