Hello
I am trying to get a MEAN application up and going. I have learned
(barely) each individual piece and now it is time to code.
I must be missing something and I think it is the client / server
javascript that is throwing me off.
This is what I have
express MeanTest --ejs
cd MeanTest && npm install
npm install mongodb --save
then I add the following code to the files below.
app.js (under the other 'requires')
var mongoDbInstance = require('mongodb').MongoClient;
index.ejs
<!DOCTYPE html>
<html ng-app="phonecatApp">
<head>
<title><%= title %></title>
<link rel='stylesheet' href='/stylesheets/style.css' />
<script src="/javascripts/angular.min.js" ></script>
<script src="/javascripts/countriesCtrl.js"></script>
</head>
<body>
<h1><%= title %></h1>
<p>Welcome to <%= title %></p>
<div>
<label>Name:</label>
<input type="text" ng-model="yourName" placeholder="Enter a name
here">
<hr>
<h1>Hello {{yourName}}!</h1>
</div>
<div ng-controller="PhoneListCtrl">
<table border="1" cellspacing="0" cellpadding=3>
<tr><td>Abbreviation</td><td>Name</td></tr>
<tr ng-repeat="state in states">
<td>{{state.abbreviation}}</td><td>{{state.name}}</td>
</tr>
</table>
</div>
</body>
</html>
countriesCtrl.js
var phonecatApp = angular.module('phonecatApp', []);
phonecatApp.controller('PhoneListCtrl', function ($scope) {
var db = mongoDbInstance.connect('mongodb://127.0.0.1:27017/website',
function(err, db) {
if(err) {
console.log("error");
throw err;
}
else
{
console.log("no error");
}
console.log("connected to the mongoDB !");
myCollection = db.collection('test_collection');
});
$scope.states = myCollection;
});
The error I get is below, probably because it the instance is declared in
the server and the client doesnt know about it.
So my question is, how can I get the data to the client?
Error: mongoDbInstance is not defined
I have read example after example and none of them so far address this
question. Thanks in advance.
