This is the tasks.js code I'm trying to run:
/*jslint node:true*/
var express = require('express');
var router = express.Router();
var mongojs = require('mongojs');
var db = mongojs('mongodb://localhost:27017/tasks', ['tasks']);
router.get('/tasks', function (req, res, next) {
'use strict';
db.tasks.find(function(err, tasks) {
if(err){
res.send(err);
}
res.json(tasks);
});
});
module.exports = router;
The code is meant to query and display all the contents of the json file.
When I replace the db localhost URL with this mLab URL:
var db = mongojs('mongodb://username:password@ds161008.mlab.com:61008/mytasklist_muhab', ['tasks']);
It works perfectly.
I assume there is a problem with the string. I looked up the connectionString standards in MongoDB docs and I couldn't locate the problem.
I haven't assigned any username or password to the local database.
Mongod is running fine and I am able to run commands on the same database using the Mongo shell without any problem.
According to mongojs documentation you may no need to use mongodb://localhost:27017 as part of your connectionString for local db can try by only dbName
like:
var db = mongojs('tasks', ['tasks'])
or
var db = mongojs('tasks')
var mycollection = db.collection('tasks')
and checked your connection established or not by using error or connect event
var db = mongojs('tasks', ['tasks'])
db.on('error', function (err) {
console.log('database error', err)
})
db.on('connect', function () {
console.log('database connected')
})
