Chat is enterprise level feature to communicate between different users.

Jabber is the original open instant messaging (IM) technology, invented by Jeremie Miller in 1998 and formalized as the Extensible Messaging and Presence Protocol (XMPP) by the IETF as an Internet Standard for IM and presence. (Copied from https://www.jabber.org)

JavaScript as Server Side / Client Side

August 18, 2016 Leave a comment

JavaScript evolved a lot since its inception.

Node.jshttps://en.wikipedia.org/wiki/Node.js
In software development, Node.js is an open-source, cross-platform runtime environment for developing server-side Web applications. Although Node.js is not a JavaScript framework,[3] many of its basic modules are written in JavaScript, and developers can write new modules in JavaScript. The runtime environment interprets JavaScript using Google’s V8 JavaScript engine.
Node.js has an event-driven architecture capable of asynchronous I/O. These design choices aim to optimize throughput and scalability in Web applications with many input/output operations, as well as for real-time Web applications (e.g., real-time communication programs and browser games).

https://nodejs.org/en/
Node.js® is a JavaScript runtime built on Chrome’s V8 JavaScript engine. Node.js uses an event-driven, non-blocking I/O model that makes it lightweight and efficient. Node.js’ package ecosystem, npm, is the largest ecosystem of open source libraries in the world.

—————————
NPM: Easy to pull and use packages similar to Maven pulls jars from repos.
npm is the package manager for JavaScript. Find, share, and reuse packages of code from hundreds of thousands of developers — and assemble them in powerful new ways.
https://www.npmjs.com/

Grunt: http://gruntjs.com/
Task Runner
Why use a task runner?
In one word: automation. The less work you have to do when performing repetitive tasks like minification, compilation, unit testing, linting, etc, the easier your job becomes.
—————————
Bower https://bower.io/
Web sites are made of lots of things — frameworks, libraries, assets, and utilities. Bower manages all these things for you.

Keeping track of all these packages and making sure they are up to date (or set to the specific versions you need) is tricky. Bower to the rescue!

Bower can manage components that contain HTML, CSS, JavaScript, fonts or even image files. Bower doesn’t concatenate or minify code or do anything else – it just installs the right versions of the packages you need and their dependencies.

To get started, Bower works by fetching and installing packages from all over, taking care of hunting, finding, downloading, and saving the stuff you’re looking for. Bower keeps track of these packages in a manifest file, bower.json. How you use packages is up to you. Bower provides hooks to facilitate using packages in your tools and workflows.

Bower is optimized for the front-end. If multiple packages depend on a package – jQuery for example – Bower will download jQuery just once. This is known as a flat dependency graph and it helps reduce page load.

What’s Yeoman?

Yeoman helps you to kickstart new projects, prescribing best practices and tools to help you stay productive.

To do so, we provide a generator ecosystem. A generator is basically a plugin that can be run with the `yo` command to scaffold complete projects or useful parts.

This is like maven archetypes to generate boiler plate code with proper directory structure.

Many who are not exposed to Data Warehouse / Data Mining / Reporting won’t understand data properly.
Many times we are tempted to fetch reports from live database. Which is not correct.
