Other appearance include:
Backbone.js, aka aloof Backbone, provides anatomy to JavaScript-heavy application. It appearance models with key-value bounden and custom events, which are collections with an API accouterment enumerable functions and angle with allegorical event-handling.
You can download both development and assembly versions of Backbone.js from the Backbone activity website.
Data in Backbone.js is represented as models, which can be created, validated, destroyed, and adored to the server. The models are affiliated to applications via a RESTful JSON interface. With Backbone.js, the archetypal triggers a change accident back a UI activity prompts an aspect of a archetypal to change. Angle announcement the model’s accompaniment can be notified of this change and re-render themselves.
Ember.js is a framework that emphasizes out-of-the-box productivity. It appearance chip templates, alleged handlebars, that are advised to abate code-writing; these templates amend automatically back abstracts changes.
You can install Ember.js via NPM by accounting npm install -g ember-cli@2.15.
Ember.js’s appearance include:
Ember.js 3.0’s abiding absolution is due February 12, 2018, afterward a beta absolution on January 1. APIs deprecated during 2.x but still accurate will be purged in Ember.js 3.x. An add-on will supports Ember.js 2x APIs in the 3.x line.
Unlike added arresting JavaScript frameworks, Sencha’s Ext JS is not accessible source; it is a bartering product. It is for architectonics enterprise-oriented, data-intensive, cross-platform web apps for assorted anatomy factors.
The Ext JS software be downloaded from Sencha’s Ext JS page.
The Ext JS framework offers abounding components, such as for abstracts grids and calendars. Ext JS works with accoutrement such as Sencha Architect, for drag-and-drop HTML5 appliance development, and Sencha Themer, for administration of apps.
Ext JS’s builders are absorption area to go continued appellation with Ext JS’s architecture. Sencha had planned on absolution Ext JS 7 either backward this year or aboriginal abutting year but those affairs are now on hold, due to Sencha’s accretion by Idera. Discussions accept been captivated about possibly alms acquiescence with the latest ECMAScript accepted and appliance the NPM amalgamation administrator and the Webpack bore bundler.
The jQuery JavaScript library appearance an API for functions such as HTML certificate manipulation, event-handling, and animation. Under the administration of the JS Foundation, the jQuery library was aboriginal fabricated accessible in August 2006.
The jQuery software can be downloaded from the jQuery activity website.
Although not a framework for architectonics applications, jQuery provides an elegant, lower-level API to accomplish alive with the DOM accessible beyond browsers. jQuery can be acclimated with application-building accoutrement like Angular and React/Redux.
The jQuery aggregation is now accomplishing about two releases a year, with aloof accessory versions due amid now and mid-2018. Beyond that, jQuery 4.0 and consecutive releases alarm for a complete carbon appliance “next-generation” JavaScript, acute an amend to the body system. Additionally planned for jQuery 4 and afterwards versions:
Meteor, aka Meteor.js, is a JavaScript framework to accredit quicker development of apps for the web, mobile, and desktop appliance beneath code. Developers can use JavaScript for all environments, including the appliance server, web browser, and adaptable device.
The Meteor software can be downloaded from the Meteor activity website.
The Meteor platform, additionally accepted as Meteor.js, includes technologies for architectonics connected-client acknowledging applications, a body tool, and a set of bales from the Node.js and JavaScript community. With Meteor, the server sends data—not HTML—over the wire, with the applicant apprehension it.
Meteor 1.6 is the abutting appointed release, with a focus on advance to Node.js 8, which will let Meteor booty bigger advantage of ECMAScript appearance on the server, which should advance body performance.
Google’s Polymer JavaScript library is advised to accredit developers to booty advantage of web components, accouterment for reusable custom elements to interoperate with a browser’s congenital elements.
You can install Polymer from the Bower amalgamation manager.
Polymer Adaptation 2.0, released in May, bigger interoperability by removing the charge to use Polymer.dom for DOM manipulation. This makes it easier to use Polymer apparatus with added libraries and frameworks.
Other appearance in Polymer 2.0 include:
On the cartoon lath is Polymer 3.0, which is in a examination anatomy and switches from the Bower and HTML imports to NPM and ECMAScript 15 modules. Bower and HTML imports had formed for an HTML imports-based workflow. But they put Polymer alfresco the boilerplate of web development, and fabricated it adamantine for bodies alive with added frameworks or body tools.
Facebook’s React library for architectonics UIs, offers allegorical angle and is component-based, with basic argumentation accounting in JavaScript. The React library, additionally accepted as React.js, does not abutment models or controllers, but added accompanying projects do awning these functions.
