![]() Backbone now registers itself for AMD (Require.js), Bower and Component, as well as being a CommonJS module and a regular (Java)Script.Bugfix for route parameters with newlines in them.If you'd like to have Backbone use jQuery from Node, assign it like so: Backbone.$ = require('jquery') Backbone no longer tries to require jQuery in Node/CommonJS environments, for better compatibility with folks using Browserify.On March 29, 2022, React 18 was released which introduced a new concurrent renderer, automatic batching and support for server side rendering with Suspense. On August 10, 2020, the React team announced the first release candidate for React v17.0, notable as the first major release without major changes to the React developer-facing API. On September 26, 2017, React 16.0 was released to the public. JavaScript functions and virtual DOM objects are called "fibers", and each can be operated and updated separately, allowing for smoother on-screen rendering. Likewise, the structure of a page can be broken into segments that may be maintained and updated separately. Fiber breaks down animation into segments that can be spread out over multiple frames. Stack was slow to draw complex animation, for example, trying to accomplish all of it in one chunk. React's old rendering system, Stack, was developed at a time when the focus of the system on dynamic change was not understood. The actual syntax for programming with React does not change only the way that the syntax is executed has changed. React Fiber was to become the foundation of any future improvements and feature development of the React library. On April 18, 2017, Facebook announced React Fiber, a new set of internal algorithms for rendering, as opposed to React's old rendering algorithm, Stack. React Native, which enables native Android, iOS, and UWP development with React, was announced at Facebook's React Conf in February 2015 and open-sourced in March 2015. It was open-sourced at JSConf US in May 2013. It was first deployed on Facebook's News Feed in 2011 and later on Instagram in 2012. He was influenced by XHP, an HTML component library for PHP. React was created by Jordan Walke, a software engineer at Meta, who released an early prototype of React called "FaxJS". This enables the React community to provide feedback on new potential features, experimental APIs and JavaScript syntax improvements. However, major changes to React go through the Future of React repository issues and pull requests. ![]() Project status can be tracked via the core team discussion forum. It provides an API that is consistent with Redux, enabling developers to create Redux-like stores that are local to component states. In February 2019, useReducer was introduced as a React hook in the 16.8 release. Many implementations of Flux have been created since its inception, perhaps the most well-known being Redux, which features a single store, often called a single source of truth. ![]() This pattern is sometimes expressed as "properties flow down, actions flow up". The stores, which can be thought of as models, can alter themselves in response to actions received from the dispatcher. The action is an object whose responsibility is to describe what has taken place: for example, an action describing one user "following" another might contain a user id, a target user id, and the type USER_FOLLOWED_ANOTHER_USER. Ī React component under the Flux architecture should not directly modify any props passed to it, but should be passed callback functions that create actions which are sent by the dispatcher to modify the store. įlux can be considered a variant of the observer pattern. Since its conception, Flux has been superseded by libraries such as Redux and MobX. When used with React, this propagation is accomplished through component properties. Flux features actions which are sent through a central dispatcher to a store, and changes to the store are propagated back to the view. To support React's concept of unidirectional data flow (which might be contrasted with AngularJS's bidirectional flow), the Flux architecture was developed as an alternative to the popular model–view–controller architecture. Common patterns of usage have emerged as the library matures. This allows the choice of whichever libraries the developer prefers to accomplish tasks such as performing network access or local data storage. It is designed specifically for building user interfaces and therefore does not include many of the tools some developers might consider necessary to build an application. React does not attempt to provide a complete application library.
