heroku+node.jsでHello Worldしてみた(2)

続きです。

6.Dashboardから新規アプリ作成

ここで、herokuのDashboardを見ると、作成したサンプルアプリが見えています。今回の場合、mysterious-river-xxxxが作成したサンプルアプリです。

screen-1003

また、右上の「+」が新規アプリ作成に使用するボタンのようです。

「+」を押すと新規アプリケーションの名前を聞いてきます。ただ、optionalなので、そのまま「Create App」してみます。

Screenshot-1004

 

whispering-lake-8767」という名前のアプリになったようです。続けてやるべきことが記載されています。これに沿って、アプリケーションのリポジトリを作成してみます。

~/heroku $ mkdir hello-heroku
~/heroku $ cd hello-heroku/
~/heroku/hello-heroku $ git init
Initialized empty Git repository in /home/xxx/heroku/hello-heroku/.git/
~/heroku/hello-heroku $ heroku login
Enter your Heroku credentials.
Email: xxxxxxxxxx@xxxxx.xxx
Password (typing will be hidden): 
Authentication successful.
~/heroku/hello-heroku $ heroku git:remote -a whispering-lake-8767
Installing Heroku Toolbelt v4... done
Installing plugin heroku-git... done
set git remote heroku to https://git.heroku.com/whispering-lake-8767.git
~/heroku/hello-heroku $

として、アプリケーションのリポジトリを作りました。

7. Node.jsでアプリケーションを作成

以下の内容のサンプルアプリを作ってみました。内容は参考にさせていただいたこちらのサイトそのままです。ファイル名はhello.jsとしました。

var express = require("express");
var app = express();
app.use(express.logger());

app.get('/', function(request, response) {
	response.send('Hello Heroku world!');
})

var port = process.env.PORT || 5000;
app.listen(port, function() {
	console.log("Listening on " + port);
});

8. package.jsonファイルを作成

次に、packages.jsonファイルを作成します。

~/heroku/hello-heroku $ npm init
This utility will walk you through creating a package.json file.
It only covers the most common items, and tries to guess sane defaults.

See `npm help json` for definitive documentation on these fields
and exactly what they do.

Use `npm install <pkg> --save` afterwards to install a package and
save it as a dependency in the package.json file.

Press ^C at any time to quit.
name: (hello-heroku) 
version: (1.0.0) 0.0.1
description: Study for heroku and node.js
entry point: (hello.js) 
test command: 
git repository: https://git.heroku.com/whispering-lake-8767.git
keywords: Hello World
author: 
license: (ISC) 
About to write to /home/tom/heroku/hello-heroku/package.json:

{
  "name": "hello-heroku",
  "version": "0.0.1",
  "description": "Study for heroku and node.js",
  "main": "hello.js",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1"
  },
  "repository": {
    "type": "git",
    "url": "https://git.heroku.com/whispering-lake-8767.git"
  },
  "keywords": [
    "Hello",
    "World"
  ],
  "author": "",
  "license": "ISC"
}


Is this ok? (yes) 
~/heroku/hello-heroku $

 

これで packages.jsonファイルが作成されました。
・・・が、(予想通りですが)依存関係などは手動で追加のようです。

各パッケージのバージョンを調べます。

~/heroku/hello-heroku $ node -v
v0.10.37
~/heroku/hello-heroku $ npm --version
1.4.28
~/heroku/hello-heroku $ npm view express version
4.13.1
~/heroku/hello-heroku $

ということで、packages.jsonファイルを修正します。

{
  "name": "hello-heroku",
  "version": "0.0.1",
  "dependencies": {
    "express": "4.13.x"
  },
  "engines": {
    "node": "0.10.x",
    "npm": "1.4.x"
  }
}

9. npmで必要なパッケージをインストール

npmで必要になるパッケージをインストールします。

~/heroku/hello-heroku $ npm install
npm WARN package.json hello-heroku@0.0.1 No description
npm WARN package.json hello-heroku@0.0.1 No repository field.
npm WARN package.json hello-heroku@0.0.1 No README data

└── accepts@1.2.11 (negotiator@0.5.3, mime-types@2.1.3)
~/heroku/hello-heroku $

10. Procfileの作成

Procfileを作成してプロセスタイプを宣言します。

web: node hello.js

ここまでで以下のファイルが準備できました。

~/heroku/hello-heroku $ ls -la
合計 28
drwxr-xr-x 4 xxx xxx 4096  7月 23 13:06 .
drwxr-xr-x 4 xxx xxx 4096  7月 23 12:28 ..
drwxr-xr-x 7 xxx xxx 4096  7月 23 12:29 .git
-rw-r--r-- 1 xxx xxx   20  7月 23 13:06 Procfile
-rw-r--r-- 1 xxx xxx  280  7月 23 12:36 hello.js
drwxr-xr-x 3 xxx xxx 4096  7月 23 12:50 node_modules
-rw-r--r-- 1 xxx xxx  162  7月 23 12:49 package.json
~/heroku/hello-heroku $

11. ローカルからアプリを動かしてみる。

ローカルからアプリを動かしてみると・・・

~/heroku/hello-heroku $ foreman start
13:08:41 web.1  | started with pid 3965
13:08:41 web.1  | 
13:08:41 web.1  | Error: Most middleware (like logger) is no longer bundled with Express and must be installed separately. Please see https://github.com/senchalabs/connect#middleware.

13:08:41        |     at node.js:935:3
~/heroku/hello-heroku $

となってエラーになってしまいました。
読んでみると、「たいていのミドルウェア(loggerのようなもの)はExpressにはもはやバンドルされてないので個別にインストールしなきゃダメよ。https://github.com/senchalabs/connect#middleware を見てね。」だそうです。

が、リンク先を見ても特にloggerに関する記載はないので、ソースコードを

var express = require("express");
var app = express();
//app.use(express.logger());

app.get('/', function(request, response) {
	response.send('Hello Heroku world!');
})

var port = process.env.PORT || 5000;
app.listen(port, function() {
	console.log("Listening on " + port);
});

 

として、loggerをコメントアウトして使わないようにしてみました。
すると、

~/heroku/hello-heroku $ foreman start
13:18:58 web.1  | started with pid 4082
13:18:58 web.1  | Listening on 5000

となって、無事起動している模様。ブラウザで見てみると、

Screenshot-Mozilla Firefox

となり、無事に表示されました。

12. herokuでアプリを動かす

herokuで動かしてみます。ログが長いですが、後で見返すときのためにそのままで。

~/heroku/hello-heroku $ 

ブラウザで見てみます。

Screenshot-Mozilla Firefox-1

無事に動作しているようです。

※1:「$ heroku create」だけを実行すると、適当な名前でアプリが作成されてしまうようです。リポジトリの名前との関係が今ひとつ理解できていません。
※2:上記の例ではFirefoxでURLを手打ちしましたが、「$ heroku open」でブラウザが開いてアプリを動かしてくれます。

13. メッセージを変えてみる

ソースファイルを以下の通り修正してみました。

var express = require("express");
var app = express();
//app.use(express.logger());

app.get('/', function(request, response) {
	response.send('Hello wonderful Heroku world!');
})

var port = process.env.PORT || 5000;
app.listen(port, function() {
	console.log("Listening on " + port);
});

herokuにアップロードして確認します。
