The wondrous world of JavaScript

The wondrous world of JavaScript | Development on Various Platforms | Scoop.it

If you’re following the latest trends in the web development world, you might have noticed that the last years the popularity of JavaScript increased a lot. Lots of frameworks became popular like Google’sAngularJS, ember.js and of course Backbone.js.

One of the first of these “big” frameworks was Backbone.js. JavaScript code before that time was usually unstructured, contained a lot of spaghetti code and was hard to maintain.
Backbone.js gave you the possibility to follow the MVC (Model-view-controller) design paradigm, or in their case, MVP (Model-view-presenter).

Backbone.js gave you the possibility to divide your application in logical parts andprovided data binding. Only that wasn’t enough of course, because applications needed more components like:
* A module system
* Templating
* Data binding
* Data synchronisation
* Widgets
* Testing framework

And so, other frameworks were born, like: RequireJS, CommonJS, Component, AngularJS, Twitter Bootstrap, Flight, Hogan.js, QUnit, Jasmine, … (and I can probably go on for another hour).

AngularJS and Authentication with CouchDB

AngularJS and Authentication with CouchDB | Development on Various Platforms | Scoop.it

Through the first 3 parts of this series we now have a scalable voting application that can process votes for events via SMS or voice and display the real-time progress of voting. However, there is currently no web interface for an administrator. Creating events or modifying them require making changes directly to the documents in CouchDB. In this blog post, I will walk through the process of creating a simple web interface for administrators using AngularJS.

Knockout.js Query Builder

Knockout.js Query Builder | Development on Various Platforms | Scoop.it

On my current project we are in need of a dynamic query-building user interface. In non-geek terms, that means a web page that allows a user to specify fields, constraints, and values that evaluate to some kind of query or expression. Alright that was still a geeky explanation... but if you're reading this then the geek-speak is probably appropriate for you. But I digress...

This little UI is all about the data structure you want the UI to represent. If you can plan the data structure, you can throw the UI on top of it. There may be specific theories and methods on how to properly represent a logical query like this, but I'm not following any particular approach here.

My data structure is as follows:

* Condition - a unit of logic that defines a field, comparison operator, and value (e.g. Color equals 'Black', Quantity is greater than two, etc).

* Group - contains an array of Conditions and Groups, and specifies whether to perform a logical-AND or a logical-OR on all items in the array.

MongoDB solves problems MySQL didn't solve at the time

Hacker News comments on the article "MongoDB Days" here: http://gaiustech.wordpress.com/2013/04/13/mongodb-days/

 

Last week I attended MongoDB Day London. Now MongoDB itself is a technology that I’m fairly interested in, I can see where it would have its uses. But the problem is the people! They all talk like this:

* Some problem that just doesn’t really exist (or hasn’t existed for a very long time) with relational databases

* MongoDB

* Profit!

 

So anyway, since it’s free‡, there’s no reason not to evaluate MongoDB, and see if it suits your use cases. But just remember that these kids think they’re solving problems that IBM (et al) solved quite literally before they were born in some cases, and the features are probably already there in your existing database/technology stack (I have used Oracle for my rebuttals just because I am most familiar with it, but I expect the same is true for SQL Server and DB/2 as well). Talk to your friendly local DBA…
