MEANスタックの紹介として、私はローカルでgithubのthisの例を実行していました。これは非常に基本的なコンタクトリストCRUDアプリケーションであり、単一のテーブル（またはドキュメント？）を持ちます。平均スタックアプリケーション内でmongodbから "404 not found"を取得する
ガイドに従って、自分のローカルにmongodbを正常にインストールしました。
server.js：
var express = require('express');
var app = express();
var mongojs = require('mongojs');
var db = mongojs('contactlist', ['contactlist']);
var bodyParser = require('body-parser');
app.use(express.static(__dirname + '/public'));
app.use(bodyParser.json());
app.get('/contactlist', function (req, res) {
console.log('I received a GET request');
db.contactlist.find(function (err, docs) {
console.log(docs);
res.json(docs);
});
});
app.post('/contactlist', function (req, res) {
console.log(req.body);
db.contactlist.insert(req.body, function(err, doc) {
res.json(doc);
});
});
app.delete('/contactlist/:id', function (req, res) {
var id = req.params.id;
console.log(id);
db.contactlist.remove({_id: mongojs.ObjectId(id)}, function (err, doc) {
res.json(doc);
});
});
app.get('/contactlist/:id', function (req, res) {
var id = req.params.id;
console.log(id);
db.contactlist.findOne({_id: mongojs.ObjectId(id)}, function (err, doc) {
res.json(doc);
});
});
app.put('/contactlist/:id', function (req, res) {
var id = req.params.id;
console.log(req.body.name);
db.contactlist.findAndModify({
query: {_id: mongojs.ObjectId(id)},
update: {$set: {name: req.body.name, email: req.body.email, number: req.body.number}},
new: true}, function (err, doc) {
res.json(doc);
}
);
});
app.listen(3000);
console.log("Server running on port 3000");
公開/コントローラ/ controller.js：
var myApp = angular.module('myApp', []);
myApp.controller('AppCtrl', ['$scope', '$http', function($scope, $http) {
console.log("Hello World from controller");
var refresh = function() {
$http.get('/contactlist').success(function(response) {
console.log("I got the data I requested");
$scope.contactlist = response;
$scope.contact = "";
});
};
refresh();
$scope.addContact = function() {
console.log($scope.contact);
$http.post('/contactlist', $scope.contact).success(function(response) {
console.log(response);
refresh();
});
};
$scope.remove = function(id) {
console.log(id);
$http.delete('/contactlist/' + id).success(function(response) {
refresh();
});
};
$scope.edit = function(id) {
console.log(id);
$http.get('/contactlist/' + id).success(function(response) {
$scope.contact = response;
});
};
$scope.update = function() {
console.log($scope.contact._id);
$http.put('/contactlist/' + $scope.contact._id, $scope.contact).success(function(response) {
refresh();
})
};
$scope.deselect = function() {
$scope.contact = "";
}
}]);
