Angular CLI で作成したアプリをHerokuへデプロイする方法

More than 3 years have passed since last update.

事前準備

事前準備は以下を参考に作成する
Herokuにアカウント登録してアプリを作成する

ng new で作成したPJにすること

express をインストール

cd your-app-name
npm install express --save

pacage.jsonの記述を変更する

  • scripts内のstartの内容をnode server.jsに変更
  • scripts内にpostinstallを追加
  "scripts": {
    "start": "node server.js",
    "postinstall": "ng build --aot --target=production"
  },
  • devDependenciesに記述されているangular系とtypescriptをdependenciesへ移動する

  • enginesを追加する

  "engines": {
    "node": "6.10.3",
    "npm": "3.10.10"
  }

}

server.jsを作成する

  • your-app-name 直下に作成する
const express = require('express');
const app = express();
app.use(express.static(__dirname + '/dist'));
app.listen(process.env.PORT || 8080);
const path = require('path');
app.get('/*', function(req, res){
  res.sendFile(path.join(__dirname + '/dist/index.html'));
});
console.log('Server listening on port 8080');

Heroku へデプロイ

heroku login
# gitが初めての場合、git initする

heroku git:clone -a [heroku-app-name]
cd your-app-name
git add .
git commit -am "make it better"
git push heroku master
