26-397: Similar techniques include Ember.js ' Glimmer and Angular 's incremental DOM. The JavaScript DOM API has historically been inconsistent across browsers, clunky to use, and difficult to scale for large projects. While libraries like jQuery aimed to improve the overall consistency and ergonomics of interacting with HTML, it too was prone to repetitive code that didn't describe the nature of

52-523: A RESTful JSON API that implements the JSON API specification, provided certain conventions are followed. However it is also configurable and can work with servers through the use of adapters and addons. JSON API has server library implementations for PHP , Node.js , Ruby , Python , Go , .NET and Java . Connecting to a Java- Spring -based server is also documented. The first stable version of Ember Data (labeled 1.13 to align with Ember itself)

78-496: A bug tracking tool called Exceptional. After selling Exceptional to Rackspace in 2011, they used the proceeds to start Intercom. In 2012 Twitter co-founder Biz Stone invested an undisclosed sum in Intercom. Shortly after, the company received seed funding from David Sacks , Huddle founder Andy McLoughlin, and others like Dan Martell, 500 Global (previously 500 Startups ), and Digital Garage. In March 2013 it announced

104-476: A $ 125 million Series D round led by Kleiner Perkins , with participation from Google Ventures . In June 2020, Intercom's founder and then chief executive officer Eoghan McCabe announced at an internal company "all hands" meeting that he would be moving to the role of chairman and standing down as CEO. Karen Peacock was announced as Intercom's new chief executive, effective July 1, 2020. A year before, McCabe had admitted to 'poor judgment' with female staff but

130-427: A $ 6 million Series A round led by Social Capital . In January 2014 it received a $ 23 million Series B funding led by Bessemer Venture Partners . Intercom also received a $ 50 million Series C-1 funding led by Index Ventures . In 2017 Intercom offered to pay the legal fees for those affected by US president Donald Trump ’s proposal to ban Muslims who wanted to relocate to Ireland. In 2018, Intercom announced

156-469: A framework for the web, it is also possible to build desktop and mobile applications with Ember when utilizing a hybrid app pattern . The most notable example of an Ember desktop application is Apple Music , a feature of the iTunes desktop application. The Ember trademark is owned by Tilde Inc. In December 2011, the SproutCore 2.0 framework was renamed to Ember.js, to reduce confusion between

182-455: A highly opinionated framework built to be very flexible. According to the company, Ember consists of five key concepts: Ember.js is one component of a complete front-end stack built and supported by the Ember core team. Ember-CLI aims to bring convention over configuration to build tools. A command line utility based on broccoli , running the command ember new <app-name> generates

208-430: A new Ember app with the default stack. This provides: Other features include: Most Ember applications use Ember Data, a data-persistence library providing many of the facilities of object-relational mapping (ORM). However it is also possible to use Ember without Ember Data. Ember Data maps client-side models to server-side data. It can then load and save records and their relationships without any configuration via

234-495: A single route. It provides a DSL for solidifying spatial route relationships, cleanly separated from view-layer implementation details. An example would be to animate a screen transition so that the new screen appears to slide in from one edge of the browser. See the releases blog for the full list of releases and detailed changelog. Ember follows a six-week release cycle, inspired by the rapid release cycle of Google Chrome . Starting with Ember 2.0, related projects supported by

260-483: A variable in their scope changed. This digest cycle provided a framework to write more declarative code that coupled logic and markup in a more logical way. While AngularJS aimed to provide a more declarative experience, it still required data to be explicitly bound to and watched by the DOM, and performance concerns were cited over the expensive process of dirty checking hundreds of variables. To alleviate these issues, React

286-627: Is a software company that specializes in business messaging, providing businesses with a way to chat with their customers. Intercom has its headquarters in San Francisco with offices in Chicago , Dublin , Sydney and London . Intercom was founded in California in 2011 by four Irish designers and engineers, Eoghan McCabe, Des Traynor, Ciaran Lee, and David Barrett. They previously ran Irish software design consultancy Contrast, which made

312-543: Is an open-source JavaScript web framework that utilizes a component-service pattern . It is designed to allow developers to create scalable single-page web applications by incorporating common idioms , best practices, and patterns from other single-page-app ecosystem patterns into the framework. Ember is used on many websites including HashiCorp , DigitalOcean , Apple Music , Square, Inc. , Intercom , Discourse , Groupon , LinkedIn , Live Nation , Ghost , Nordstrom , and Twitch . Although primarily considered

338-431: The render() function, while in functional hook-based components, the return value of the function itself serves as the page markup. Vue.js uses a virtual DOM to handle state changes, but is usually not directly interacted with; instead, a compiler is used to transform HTML templates into virtual DOM nodes as an implementation detail. While Vue supports writing JSX and custom render functions, it's more typical to use

364-559: The Request For Comment process. This gives the Ember community a chance to give feedback on new proposals. Notable RFCs include: Unlike other projects such as AngularJS ( Google ) and React ( Facebook ) which have the backing of one main company, Ember.js has a variety of sponsors and backers. These include users of the framework such as Yahoo! , LinkedIn and Bustle . Intercom (company) For voice communications systems, see Intercom . Intercom, Inc.

390-408: The application framework and the widget library of SproutCore 1.0. The framework was created by Yehuda Katz, a member of the jQuery , Ruby on Rails and SproutCore core teams. According to the company, Ember was designed around four key ideas: Like Ruby on Rails, Ember follows convention over configuration (CoC), and the don't repeat yourself (DRY) principle. It has been described as

416-407: The changes being made well and decoupled logic from markup. The release of AngularJS in 2010 provided a major paradigm shift in the interaction between JavaScript and HTML with the idea of dirty checking . Instead of imperatively declaring and destroying event listeners and modifying individual DOM nodes, changes in variables were tracked and sections of the DOM were invalidated and rerendered when

442-597: The company. McCabe was reappointed by the company's board as the CEO in October 2022. In July 2023, Intercom withdrew its public support for Pride celebrations, including removing flags from offices in Dublin. Subsequently, McCabe came under pressure from staff for retweeting contentious tweets on Twitter. At a company-wide meeting, he promised to be more thoughtful in his use of the platform. In 2023, Intercom ended support for

468-571: The console. If Ember Data is used, one can also see the records loaded for each model. Fastboot is an Ember CLI add-on created by the Ember core team that gives Ember developers the ability to run their apps in Node.js . This feature allows end users to see HTML and CSS right away, with JavaScript downloading in the background and taking over once it has fully loaded. Liquid Fire provides animation support for Ember applications. Features include animated transitions between routes and between models within

494-408: The core team have their releases coordinated, and share a version number with Ember itself. Ember follows the semantic versioning convention. In particular, breaking changes are only introduced at significant version numbers, such as 1.0, 2.0, etc. While new features can be added at point releases (1.1, 1.2...), and features deprecated, no breaking changes to the public APIs are introduced. Tooling

520-463: The template compiler since a build step isn't required that way. Svelte does not have a virtual DOM, with its creator Rich Harris calling the virtual DOM "pure overhead". Instead of diffing and reconciling DOM nodes at runtime, Svelte uses compile-time reactivity to analyze markup and generate JavaScript code that directly edits the HTML, drastically increasing performance. Ember.js Ember.js

546-565: The virtual DOM has been criticized for being slow due to the additional time required for diffing and reconciling DOM nodes. This has led to the development of frameworks without a virtual DOM, such as Svelte , and frameworks that edit the DOM in-place such as Angular 2 . React pioneered the use of a virtual DOM to make components declaratively. Virtual DOM nodes are constructed using the createElement() function, but are often transpiled from JSX to make writing components more ergonomic. In class-based React, virtual DOM nodes are returned from

572-466: Was also under development in 2015 to help streamline the upgrade process. In addition to this process, several steps were taken to mitigate issues around upgrading to the 2.0 release: The process follows the core Ember principle of Stability without Stagnation and is in marked contrast to the upgrade plans of similar projects such as AngularJS . Project status can be tracked via the core team meeting minutes. However, major changes to Ember go through

598-427: Was entirely encapsulated. Its release also came with the advent of JSX , which further coupled HTML and JavaScript with an XML-like syntax extension. Following React's success, many other web frameworks copied the general idea of an ideal DOM representation in memory, such as Vue.js in 2014, which used a template compiler instead of JSX and had fine-grained reactivity built as part of the framework. In recent times,

624-492: Was released on June 18 June 2015. The Ember Inspector is an extension currently available for the Mozilla Firefox and Google Chrome web browsers for debugging Ember applications. Features include the ability to see which templates, components, and views are currently rendered, see the properties of any Ember object with a UI that computes bindings and computed properties, and access one's application's objects from

650-471: Was supported by Peacock, then the chief operating officer, who called him "an exceptional leader who is visionary and strategic, as well as kind, genuine and transparent". McCabe was accused of slapping the buttocks of a female employee and propositioning another one after a night of drinks, however, both internal & external investigations cleared McCabe of wrongdoing. In July 2021, Intercom's co-founder and then chief technology officer (CTO) Ciarán Lee left

676-399: Was the first major library to adopt a virtual DOM in 2013, which removed both the performance bottlenecks (since diffing and reconciling the DOM was relatively cheap) and the difficulty of binding data (since components were effectively just objects). Other benefits of a virtual DOM included improved security since XSS was effectively impossible and better extensibility since a component's state
