OpenShiftでMEAN Stackを試してみた

OpenShiftでMEAN Stackを試してみたときのメモです。

MEANといいなが、AngularJSは、まだです....
MongoDBとの接続は、mongooseを使っています。
OpenShiftへのサインインや開発環境整備については、割愛します。

フォルダ構成

フォルダ構成は、以下のとおりです。
OpenShiftから、git clone した後、

• npm にて、必要パッケージのインストール
• package.json の修正
• server.js の修正
• app/models/bear.js の追加

を行っています。

package.jsonの設定

package.json は、こんな感じです。

package.json

{
  "name": "itheart-openshift-sample",
  "version": "1.0.0",
  "description": "OpenShift Sample Application MEAN stack",
  "keywords": [
    "OpenShift",
    "Node.js",
    "application",
    "openshift"
  ],
  "author": {
    "name": "itheart",
    "email": "[e-mail]",
    "url": "http://www.itheart.com/"
  },

    "node": ">= 0.6.0",
    "npm": ">= 1.0.0"
  },
  "dependencies": {

    "mongoose": "3.6.20",

  },
  "devDependencies": {},
  "bundleDependencies": [],
  "private": true,
  "main": "server.js",
  "jshintConfig": {
    "node": true
  }
}

server.jsの内容

server.jsは、こんな感じです。

server.js

// server.js

// BASE SETUP
// =============================================================================

// call the packages we need
/*jslint node: true */
var express    = require('express');        // call express
var app        = express();                 // define our app using express
var bodyParser = require('body-parser');
var mongoose   = require('mongoose');
var Bear       = require('./app/models/bear');

var connection_string = '127.0.0.1:27017/' + process.env.OPENSHIFT_APP_NAME;

if (process.env.OPENSHIFT_MONGODB_DB_URL) {
    connection_string = process.env.OPENSHIFT_MONGODB_DB_URL +
    process.env.OPENSHIFT_APP_NAME;
}

mongoose.connect(connection_string);


// configure app to use bodyParser()
// this will let us get the data from a POST
app.use(bodyParser());

var ipaddress = process.env.OPENSHIFT_NODEJS_IP;
var port = process.env.OPENSHIFT_NODEJS_PORT || 8080;        // set our port

// ROUTES FOR OUR API
// =============================================================================
var router = express.Router();              // get an instance of the express Router

// test route to make sure everything is working (accessed at GET http://localhost:8080/api)
router.get('/', function(req, res) {
    res.json({ message: 'hooray! welcome to our api!' });   
});

router.route('/bears')
    .post(function(req, res) {

        var bear = new Bear();
        bear.name = req.body.name;

        bear.save(function(err){
            if (err)
                res.send(err);

            res.json({ message: 'Bear Create!' });
        });
    })

    .get(function(req, res) {
        Bear.find(function(err, bears) {
            if (err)
                res.send(err);

            res.json(bears);
        });
    });

router.route('/bears/:bear_id')
    .get(function(req, res) {
        Bear.findById(req.params.bear_id, function(err, bear) {
            if (err)
                res.send(err);

            if (bear)
                res.json(bear);
            else
                res.json({ message: req.params.bear_id + ' is not found!' });
        });
    })

    .put(function(req, res) {
        Bear.findById(req.params.bear_id, function(err, bear) {
            if (err)
                res.send(err);

            if (bear) {
                bear.name = req.body.name;

                bear.save(function(err){
                    if (err)
                        res.send(err);

                    res.json({ message: 'Bear Update!' });
                });
            } else {
                res.json({ message: req.params.bear_id + ' is not found!' });
            }
        });
    })

    .delete(function(req, res) {
        Bear.remove({
            _id: req.params.bear_id
        }, function(err, bear) {
            if (err)
                req.send(err);

            if (bear)
                res.json({ message: 'Bear Delete!' });
            else
                res.json({ message: req.params.bear_id + ' is not found!' });
        });

    });

// more routes for our API will happen here

// REGISTER OUR ROUTES -------------------------------
// all of our routes will be prefixed with /api
app.use('/api', router);
app.use(express.static(__dirname + '/public'));

// START THE SERVER
// =============================================================================
app.listen(port, ipaddress);
console.log('Magic happens on port ' + port);

bear.jsの内容

bear.jsは、こんな感じです。

app/models/bear.js

var mongoose = require('mongoose');
var Schema   = mongoose.Schema;

var BearSchema = new Schema({
    name: String
});

module.exports = mongoose.model('Bear', BearSchema);

postmanによる確認

Postmanにて確認した結果は、以下のとおりです。

次は...

AngularJSを構築予定です...
