                The QuickBlox JavaScript SDK provides a JavaScript library making it even easier to access the QuickBlox cloud communication backend platform.

                QuickBlox is a suite of communication features & data services (APIs, SDKs, code samples, admin panel, tutorials) which help digital agencies, mobile developers and publishers to add great communication functionality to smartphone applications like in Skype, WhatsApp, Viber.

                Install

                Dependencies for browser

                For the library to work, you need to include either jQuery or Zepto in your html before quickblox.min.js, like so:

                Bower and RequireJS

                If you use bower package manager for your project, you can install JS SDK through bower:

                +<script src="https://cdnjs.cloudflare.com/ajax/libs/quickblox/2.5.0/quickblox.min.js"></script>

                Begin with version 2.5.0 no dependencies for work correctly is not needed.

                Bower and RequireJS

                If you use bower package manager for your project, you can install JS SDK through bower:

                bower install quickblox --save

                When you use RequireJS, you are able to use quickblox as AMD module. SDK supports UMD (Universal Module Definition) pattern for JavaScript modules. So it is possible to use SDK everywhere (as browser global variable, with AMD module loader like RequireJS or as CommonJS module for Node.js environment).

                Node.js and NPM integration

                Also you can use QuickBlox JavaScript SDK with server-side applications on NodeJS through the native node package. Just install the package in your application project like that:

                npm install quickblox --save

Sometimes it's called a "filter", -// but that's not a great name for it, since that implies a thing where -// some bits pass through, and others are simply ignored. (That would -// be a valid example of a transform, of course.) -// -// While the output is causally related to the input, it's not a -// necessarily symmetric or synchronous transformation. For example, -// a zlib stream might take multiple plain-text writes(), and then -// emit a single compressed chunk some time in the future. -// -// Here's how this works: -// -// The Transform stream has all the aspects of the readable and writable -// stream classes. When you write(chunk), that calls _write(chunk,cb) -// internally, and returns false if there's a lot of pending writes -// buffered up. When you call read(), that calls _read(n) until -// there's enough pending readable data buffered up. -// -// In a transform stream, the written data is placed in a buffer. When -// _read(n) is called, it transforms the queued up data, calling the -// buffered _write cb's as it consumes chunks. If consuming a single -// written chunk would result in multiple output chunks, then the first -// outputted bit calls the readcb, and subsequent chunks just go into -// the read buffer, and will cause it to emit 'readable' if necessary. -// -// This way, back-pressure is actually determined by the reading side, -// since _read has to be called to start processing a new chunk. However, -// a pathological inflate type of transform can cause excessive buffering -// here. For example, imagine a stream where every byte of input is -// interpreted as an integer from 0-255, and then results in that many -// bytes of output. Writing the 4 bytes {ff,ff,ff,ff} would result in -// 1kb of data being output. In this case, you could write a very small -// amount of input, and end up with a very large amount of output. In -// such a pathological inflating mechanism, there'd be no way to tell -// the system to stop doing the transform.
