JavaScript for Line of Business Applications

I know, I know it is too early to be building end to end apps with Angular 2.0.

A MEAN stack app would typically consist of a server layer built with Nodejs & Express – Express being the web framework. MongoDB for data persistence & Angular as the client side MVW framework.

First, we are going to setup an express app, build the REST API to Create, Read, Update & Delete todos and then integrate it with the Angular app.

The goal of this tutorial is to guide you through the creation of a Reddit/Hacker News clone using the MEAN stack. By completing this tutorial, you will gain a basic understanding of the MEAN stack including building a REST interface with Express.js on top of Node.js and using that interface to perform CRUD operations on a database via an AngularJS frontend.

In this post, we will see how we can leverage the power of Meteor js to build top quality apps at lightning pace. We will take a quick look at how the framework works and how we can leverage it to build apps easily.

By the end of this post, we will be building 2 apps. A Single Page Chat Application (SPA)  only with Meteor js to get a feel of Meteor & a Multi Page Application (MPA) named Events Feed, leveraging Meteorite js – a package manager for Meteor js & Iron router, that will serve the purpose of a Chat app at live public events.

Migrating from MongoDB to PostgreSQL

While we can be extremely proud of what we have achieved so far there was always something lurking in the dark: our primary database. From the start of Olery we’ve had a database setup that involved MySQL for crucial data (users, contracts, etc) and MongoDB for storing reviews and similar data (essentially the data we can easily retrieve in case of data loss). While this setup served us well initially we began experiencing various problems as we grew, in particular with MongoDB. Some of these problems were due to the way applications interacted with the database, some were due to the database itself.

Today we’ll be looking at code samples to handle CRUD operations in a Node.js, ExpressJS, and MongoDB application. We’ll use the popular Node package, mongoose.

Mongoose allows us to have access to the MongoDB commands for CRUD simply and easily. 

In this tutorial we are going to build a character voting app (inspired by Facemash) for EVE Online - a massively multiplayer online game. You will learn how to build a REST API with Node.js, save and retrieve data from MongoDB, track online visitors in real-time using Socket.IO, build a single-page app experience using React + Flux with server-side rendering and then finally deploy it to the cloud.

So, I went back and asked why Firebase and why are you fitting Firebase in your application architecture? Here are 2 major answers

• Real time data sync
• Offline storage

After giving the above reasons a good thought, I have come up with the below architecture that will “emulate” Firebase using Websockets and Local Storage inside a Node.js/MongoD.

If this solution gets stable over a period of time, I may create a yeoman/slush generator to scaffold a Node.js/Express.js and a MongoDB app with real time data sync and offline storage capabilities.

For this post, I will use a simple Todo app as an example. 

n a previous post I explained the basics of SANE and created a simple application. In this post I'll be going one step further and adding a relationship between two tables, using Sails.js, Mongo and Ember.

Relatonships occur when one foreign key references the primary key of another. Since we'll be using a nosql data store we'll be using document references instead. We'll set the schema using Sails.js so don't worry too much about that for now.

A simple tutorial for working with Ember Data, Node, Express and MongoDB to build an api.

I have really been enjoying working with EmberJS lately, once you get over the learning curve and understand how things should relate, it becomes really fast and fun!

Lets take a look at how we can use Ember Data with Node (or io.js),Express and MongoDB. For this example lets use the Ember CLI to start an Ember application fast!

Learn how to create a Emberjs and Ember-cli compatible REST API using Node.js, Express, and Mongoose....

The express-generator is great; however, it added a couple of things we will not be needing so we will remove them now. I am removing the following because this server will only be used as an API and it will not serve a frontend, you do not need to remove them but they are not in the scope of this tutorial.

aybe a better name for this phase should be maturity. At this moment I knew where and, even more important, where NOT use MongoDB. At this age you know that MongoDB is a nice product, but a product that you should use with caution. You know that the document model is great and solves a lot of problems for you, but not all: actually, quite a few.

The wakeup call for me was my own failures with it and, most of all, the failure of others. Mostly from people that I saw getting really excited about MEAN and trying to transform the world into a nail so that MongoDB could be the perfect hammer for it. It’s the moment where some facts get into your face and shout at you:...

In this article I’m going to show you that by using the MEAN stack, building create, read, update and delete (CRUD)-heavy applications can be fast and easy. I’m going to assume you have a basic conceptual understanding of AngularJS (angularjs.org), Node.js (nodejs.org), MongoDB (mongodb.org) and Express (expressjs.com).
