Fluent Design System (codenamed " Project Neon "), officially unveiled as Microsoft Fluent Design System , is a design language developed in 2017 by Microsoft . Fluent Design is a revamp of Microsoft Design Language 2 (sometimes erroneously known as "Metro", the codename of Microsoft Design Language 1) that includes guidelines for the designs and interactions used within software designed for all Windows 10 and Windows 11 devices and platforms. The system is based on five key components: light, depth, motion, material, and scale. The new design language includes more prominent use of motion, depth, and translucency effects.
72-640: The transition to Fluent is a long-term project; aspects of the design started appearing in Windows 10 beginning with the "Fall Creators Update" released in October 2017, as well as an update to the Xbox One system software released alongside it. It was later revealed to be designed in conjunction with Windows 10X , in addition to Windows 11 which has a similar design. Fluent's key principles, or "blocks" (Light, Depth, Motion, Material, and Scale), turn away from
144-501: A component are called its state. The two primary ways of declaring components in React are through function components and class components. Function components are declared with a function (using JavaScript function syntax or an arrow function expression ) that accepts a single "props" argument and returns JSX. From React v16.8 onwards, function components can use state with the useState Hook. On February 16, 2019, React 16.8
216-616: A development kit for universal Windows applications on Xbox One, with official support for the platform and Cortana coming in summer 2016. As Microsoft continued to refine Windows 10 with the Fluent Design System , the Xbox One interface was also modified to reflect these changes by 2017. Microsoft has since continued to refine this interface to add and remove integrated features, such as inclusion of Xbox Game Pass support and removal of Cortana voice commands. Ahead of
288-593: A digital game storefront. While some portions of the Xbox Live service are free, a subscription-tier Xbox Live Gold is generally required to play most multiplayer games on the console. Starting with the Xbox 360 and continuing through its current consoles, Microsoft has offered a means for users to opt into a beta test version of the console's system software. When first launched for the Xbox 360 in September 2010, this
360-429: A full-fledged routing solution out of the box. Third-party libraries can be used to handle routing in React applications. It allows the developer to define routes, manage navigation, and handle URL changes in a React-friendly way. Another notable feature is the use of a virtual Document Object Model , or Virtual DOM . React creates an in-memory data-structure cache, computes the resulting differences, and then updates
432-527: A geometrical placement of squares and rectangular items that scrolls as a continuous vertical line, using the Metro design language that is also seen in Windows 8 , Windows 10 , and other Microsoft products. When Microsoft upgraded the Windows 8-based Core to a Windows 10-based one, they made a tour of the new user interface up on Xbox Wire, promising faster, easier navigation, improved community features and
504-401: A new set of internal algorithms for rendering, as opposed to React's old rendering algorithm, Stack. React Fiber was to become the foundation of any future improvements and feature development of the React library. The actual syntax for programming with React does not change; only the way that the syntax is executed has changed. React's old rendering system, Stack, was developed at a time when
576-520: A single store, often called a single source of truth . In February 2019, useReducer was introduced as a React hook in the 16.8 release. It provides an API that is consistent with Redux, enabling developers to create Redux-like stores that are local to component states. Project status can be tracked via the core team discussion forum. However, major changes to React go through the Future of React repository issues and pull requests . This enables
648-403: A user id, a target user id, and the type USER_FOLLOWED_ANOTHER_USER . The stores, which can be thought of as models, can alter themselves in response to actions received from the dispatcher. This pattern is sometimes expressed as "properties flow down, actions flow up". Many implementations of Flux have been created since its inception, perhaps the most well-known being Redux , which features
720-464: A variant of the observer pattern . A 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. 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
792-410: Is a free and open-source front-end JavaScript library that aims to make building user interfaces based on components more "seamless". It is maintained by Meta (formerly Facebook) and a community of individual developers and companies. React can be used to develop single-page , mobile, or server-rendered applications with frameworks like Next.js . Because React is only concerned with

#1732802400455864-452: Is a set of React components that implement Microsoft's Fluent Design System. It provides a set of pre-built components that can be used to build applications for Windows , iOS , Android , macOS and the web . Furthermore, WinUI is a native user interface framework for building Windows apps. It is built on top of Fluent Design System and provides a set of pre-built controls. Xbox One system software The Xbox system software
936-619: Is a set of icons designed by Microsoft for use in its products and services alongside the redesign of the Segoe UI font (Segoe UI Variable). The icons are rounded departing from the angular and straight Segoe MDL2 icons which were predominant during the Windows 10 era. On July 15, 2021, Microsoft announced a complete redesign of its emoji library in order to align with its Fluent Design. Aiming to make Windows as consistent and accessible as possible, Microsoft made over 1,500 emoji open source on August 10, 2022. These new Fluent emojis depart from
1008-642: Is added to content through layering in the z-axis. Depth is presented via drop shadows and Z-depth layering. This is especially apparent in the redesigned Office app in 2019. In Windows 11, the use of depth is expanded by overlapping different surfaces with different opacities of the Mica material. Motion establishes a relationship between UI elements and provides a continuity in the experience. Materials are visual effects applied to UX surfaces. In fluent design there are two main kinds of materials: occluding and transparent. Occluding materials, such as acrylic and mica, form
1080-535: Is in contrast with imperative programming . React code is made of entities called components . These components are modular and reusable. React applications typically consist of many layers of components. The components are rendered to a root element in the DOM using the React DOM library. When rendering a component, values are passed between components through props (short for "properties") . Values internal to
1152-485: Is related to the Software, (ii) by any party if such claim arises in whole or in part from any software, product or service of Facebook or any of its subsidiaries or affiliates, whether or not such claim is related to the Software, or (iii) by any party relating to the Software; or (b) that any right in any patent claim of Facebook is invalid or unenforceable. This unconventional clause caused some controversy and debate in
1224-419: Is similar to another extension syntax created by Facebook for PHP called XHP . An example of JSX code: The basic architecture of React applies beyond rendering HTML in the browser. For example, Facebook has dynamic charts that render to <canvas> tags, and Netflix and PayPal use universal loading to render identical HTML on both the server and client. Server-side rendering (SSR) refers to

Across the four generations of Xbox consoles, the software has been based on a version of Microsoft Windows and incorporating DirectX features optimized for the home consoles. The user interface, the Xbox Dashboard, provides access to games, media players, and applications, and integrates with
1368-499: Is to draw attention and illuminate information. Therefore, light establishes a relationship between the UI and the cursor or pointer. With WinUI 2.6, Microsoft has discontinued reveal highlight to match their web and mobile offerings, which do not offer reveal highlight. Furthermore, with the release of Windows 11, Microsoft has slowly been removing its use of light effects in general, instead providing intractability though animations. Depth
1440-629: The Apache License 2.0 . In October 2014, React 0.12.00 replaced this with the 3-clause BSD license and added a separate PATENTS text file that permits usage of any Facebook patents related to the software: The license granted hereunder will terminate, automatically and without notice, for anyone that makes any claim (including by filing any lawsuit, assertion or other action) alleging (a) direct, indirect, or contributory infringement or inducement to infringe any patent: (i) by Facebook or any of its subsidiaries or affiliates, whether or not such claim
1512-609: The Office apps and the Chromium -based Microsoft Edge in 2018 and 2019, respectively. Preliminary versions of the final icons were spotted in the "Meet the New Icons for Office 365" video, before more were spotted when Windows 10X was unveiled, prior to being officially revealed on December 12, 2019. These icons started appearing through Microsoft Store updates to those apps, beginning with Mail and Calendar . Segoe Fluent Icons

#17328024004551584-481: The Xbox network for online functionality. Though initial iterations of the software for the original Xbox and Xbox 360 were based on heavily modified versions of Windows, the newer consoles feature operating systems that are highly compatible with Microsoft's desktop operating systems, allowing for shared applications and ease-of-development between personal computers and the Xbox line. Across all four generations of
1656-404: The "New Xbox Experience" (NXE), on November 19, 2008, that added several new features. A major new feature was the ability to install an entire game disc onto the Xbox 360's hard drive , which decreases loading times, and significantly reduces noise due to the game being read from the hard drive and not the louder disc drive. For most games this feature also reduces the amount of time spent reading
1728-467: The "blades" for the Xbox 360 menu, namely the Marketplace, Xbox Live, Games, Media and System. In scrolling from left to right, each section would have a different-colored background signifying its own unique area but users also had the option to change all sections to one background color as well. At E3 2008 , Microsoft announced that all Xbox 360 owners would receive a new dashboard update, called
1800-446: The Flux architecture was developed as an alternative to the popular model–view–controller architecture. Flux features actions which are sent through a central dispatcher to a store , and changes to the store are propagated back to the view. When used with React, this propagation is accomplished through component properties. Since its conception, Flux has been superseded by libraries such as Redux and MobX. Flux can be considered
1872-523: The Hooks API Reference. useState and useEffect , which are the most commonly used, are for controlling state and side effects, respectively. There are two rules of hooks which describe the characteristic code patterns that hooks rely on: Although these rules cannot be enforced at runtime, code analysis tools such as linters can be configured to detect many mistakes during development. The rules apply to both usage of Hooks and
1944-540: The JavaScript to download and execute before rendering the UI. React supports SSR, which allows developers to render React components on the server and send the resulting HTML to the client. This can be useful for improving the performance of the application, as well as for search engine optimization purposes. React does not attempt to provide a complete application library. It is designed specifically for building user interfaces and therefore does not include many of
2016-474: The OS. As part of its ongoing "Windows Everywhere" approach, Microsoft revamped the operating system on Xbox to be closer to its current Microsoft Windows products to provide greater compatibility between personal computers and the Xbox line. The OS was based on Windows 8 Core at the Xbox One launch in 2013. The UI maintained the same "Metro" design that had been used in the last Xbox 360 update, and which resembled
2088-500: The React community to provide feedback on new potential features, experimental APIs and JavaScript syntax improvements. React was created by Jordan Walke, a software engineer at Meta , who initially developed a prototype called "F-Bolt" before later renaming it to "FaxJS". This early version is documented in Jordan Walke's GitHub repository. Influences for the project included XHP , an HTML component library for PHP . React
2160-479: The React user community, because it could be interpreted to empower Facebook to revoke the license in many scenarios, for example, if Facebook sues the licensee prompting them to take "other action" by publishing the action on a blog or elsewhere. Many expressed concerns that Facebook could unfairly exploit the termination clause or that integrating React into a product might complicate a startup company's future acquisition. Based on community feedback, Facebook updated
2232-415: The Software. [...] A "Patent Assertion" is any lawsuit or other action alleging direct, indirect, or contributory infringement or inducement to infringe any patent, including a cross-claim or counterclaim. The Apache Software Foundation considered this licensing arrangement to be incompatible with its licensing policies, as it "passes along risk to downstream consumers of our software imbalanced in favor of

2304-645: The Virtual DOM and determines which parts (if any) of the living DOM needs to change. Lifecycle methods for class-based components use a form of hooking that allows the execution of code at set points during a component's lifetime. JSX , or JavaScript XML, is an extension to the JavaScript language syntax. Similar in appearance to HTML, JSX provides a way to structure component rendering using syntax familiar to many developers. React components are typically written using JSX, although they do not have to be (components may also be written in pure JavaScript). JSX
2376-497: The Xbox Insider Program, testing not only included updates to the system software but upcoming game and application patches from both first and third-parties. Each iteration of the Xbox software has brought some form of backward compatibility to the newer console. On the Xbox 360, selected original Xbox games could be played through emulation after downloading an emulation profile to local storage. The Xbox One
2448-471: The Xbox platform, the user interface of the system software has been called the Xbox Dashboard. While its appearance and detailed functions have varied between console generations, the Dashboard has provided the user the means to start a game from the optical media loaded into the console or off the console's storage, launch audio and video players to play optical media discs, or start special applications for
2520-494: The Xbox such as streaming media services from third parties. The Dashboard also provides a menu of settings and configuration pages for the console that the user can adjust. The Dashboard has supported integration with the Xbox Live service since November 2002. Xbox Live provides online functionality to the Xbox, including a friends list, game achievement tracking, matchmaking support for online games, in-game communications, and
2592-500: The actual games they are playing, which is part and parcel of the company's new direction under Phil Spencer , the current head of Microsoft's Xbox division. Microsoft aims to release frequent updates to the Xbox System Software, mainly containing new or improved features and faster installation and loading times for games and apps. Along with introducing improvements and fixes for native console apps and software,
2664-897: The base layers under interactive UI elements. Transparent materials like smoke are used to emphasize immersive surfaces: Both Acrylic and Mica are disabled in a specific window when the app is no longer selected. Furthermore, both are disabled system-wide when transparency is disabled, when battery saver mode is enabled, or on low-end hardware. Background Acrylic is disabled when a window is deselected or in Windows 10 Mobile , HoloLens , or tablet mode. Apps scale across different form factors , display sizes , and 0D to 3D . Elements adapt to their screen size and are available across multiple dimensions. Conscious controls are also categorized within Scale (e.g. scrollbars and inputs that adapt to different methods of invocation) New icons with acrylic materials have been created for Microsoft programs, starting with
2736-496: The basic functionality of Windows that could be ported to other systems. Microsoft released the Xbox 360 console on November 22, 2005, a year earlier than both the Sony PlayStation 3 and Nintendo Wii . Having the advantage of the lead, Microsoft was able to experiment with various customization options for the consumer's individual consoles. The ability to customize the way the console looked with various themes to fit
2808-418: The broader industry movement towards functional programming and modular design. As React continues to evolve, it is essential for developers to consider the benefits of functional components and React Hooks when building new applications or refactoring existing ones. React itself does not come with built-in support for routing . React is primarily a library for building user interfaces, and it does not include
2880-413: The browser's displayed DOM efficiently. This process is called reconciliation . This allows the programmer to write code as if the entire page is rendered on each change, while React only renders the components that actually change. This selective rendering provides a major performance boost. When ReactDOM.render is called again for the same component and target, React represents the new UI state in
2952-416: The company". The program that Microsoft launched allows developers to build a single app that can run on a wide variety of devices, including personal computers and Xbox One video game consoles. According to Polygon , Microsoft removed the distinction between Xbox One and Windows PC, and the software has been called "Windows 10 on Xbox One". Since 2016, all Xbox One consoles could be updated to include

3024-632: The dashboard and Bing using their voice. Other updates would include cloud storage, YouTube access, and live television streaming. The new dashboard, nicknamed the "Metro" dashboard, officially went live on December 6, 2011. On July, 29, 2024, along with the discontinuation of the Microsoft Store for the Xbox 360, the Metro dashboard got its final update to remove most tabs, including the Bing tab, to only include Home, Social, and Settings. The home page
3096-407: The desktop Windows 8 interface. In November 2015, Microsoft released the "New Xbox One Experience" which replaced the base system with Windows 10 Core, allowing Universal Windows Platform apps to be available on Xbox One. According to the current head of Microsoft's Gaming division, Phil Spencer , "The importance of entertainment and games to the Windows ecosystem has become really prevalent to
3168-410: The disc, thereby helping to extend the life-span of the optical drive mechanism. The Xbox Guide was redesigned. If a user has installed any game onto their Xbox 360 hard drive, they are able to immediately start the game from the guide, whether they are in a game or in the dashboard. The update gives players the ability to create Avatars , which were required by Xbox Live. They also announced that
3240-420: The flat and outlined style of the previous emoji library used in Windows 10 and instead embrace a 3D Play-Doh feel. Furthermore, Microsoft has stated their plans to animate most of them. While the 3d animated emojis can be seen in apps such as Microsoft Teams and Skype , Windows 11 uses flat variants. Fluent design guidelines are cross-platform and can be implemented with different frameworks. Fluent UI React
3312-483: The flat concept Metro had defined, and while preserving the clean look and feel Metro introduced, Fluent renews the visuals of Aero , a design approach that was introduced in Windows Vista and Windows 7 , including blurred translucency, parallax animated patterns, drop shadows, highlight effects following mouse pointer or input gesture movements, and "faux materials" Metro once discarded. The purpose of light
3384-554: The focus of the system on dynamic change was not understood. Stack was slow to draw complex animation, for example, trying to accomplish all of it in one chunk. Fiber breaks down animation into segments that can be spread out over multiple frames. Likewise, the structure of a page can be broken into segments that may be maintained and updated separately. JavaScript functions and virtual DOM objects are called "fibers", and each can be operated and updated separately, allowing for smoother on-screen rendering. On September 26, 2017, React 16.0
3456-476: The following week, it would re-license Flow, Jest, React, and Immutable.js under a standard MIT License ; the company stated that React was "the foundation of a broad ecosystem of open source software for the web", and that they did not want to "hold back forward progress for nontechnical reasons". On September 26, 2017, React 16.0.0 was released with the MIT license. The MIT license change has also been backported to
3528-515: The front and sides of it was something very different for home console users. In system, the Xbox 360 Dashboard had the ability to have multiple profiles with password on the same console with each user being able to customize the dashboard to exactly fit their own unique style. There were premium themes available for purchase on the Xbox Live Marketplace apart from the default styles. Originally there were five tabs or sections known as
3600-661: The implementation of custom Hooks, which may call other Hooks. React server components (RSC) are function components that run exclusively on the server. The concept was first introduced in the talk "Data Fetching with Server Components". Though a similar concept to Server Side Rendering, RSCs do not send corresponding JavaScript to the client as no hydration occurs. As a result, they have no access to hooks. However, they may be asynchronous function , allowing them to directly perform asynchronous operations: Currently, server components are most readily usable with Next.js . Class components are declared using ES6 classes. They behave
3672-569: The licensor, not the licensee, thereby violating our Apache legal policy of being a universal donor", and "are not a subset of those found in the [Apache License 2.0], and they cannot be sublicensed as [Apache License 2.0]". In August 2017, Facebook dismissed the Apache Foundation's downstream concerns and refused to reconsider their license. The following month, WordPress decided to switch its Gutenberg and Calypso projects away from React. On September 23, 2017, Facebook announced that

#17328024004553744-529: The monthly updates to the Xbox System Software introduce major features that are voted on or requested by the community, though some months have included more than one update. Starting in February 2014, beta releases of updates are tested before going live to check for unwanted bugs and stability. The following table lists major updates to the Xbox One and Xbox Series X/S system software. React (software) React (also known as React.js or ReactJS )

3888-414: The process of rendering a client-side JavaScript application on the server, rather than in the browser. This can improve the performance of the application, especially for users on slower connections or devices. With SSR, the initial HTML that is sent to the client includes the fully rendered UI of the application. This allows the client's browser to display the UI immediately, rather than having to wait for
3960-539: The release of the Xbox Series X and Series S consoles in November 2020, Microsoft updated the Xbox One software to reflect changes in the Dashboard that would also be present in the newer consoles. This included improved performance in some of the storefront features and readability improvements to the interface, which were also propagated across Xbox Game Pass and mobile apps. The system software's interface uses
4032-480: The return of Xbox Avatars. The UI includes a HOME screen, consisting of the top bar, the screenshot viewer ("Album") Icons, and shortcuts to the Microsoft Store , News, and Settings. The main feature on the home screen is a list of the most recently played games. Selecting any given title will give users more information about announcements, achievements, social activity and so forth. It is also more focused on
4104-451: The same way that function components do, but instead of using Hooks to manage state and lifecycle events, they use the lifecycle methods on the React.Component base class . The introduction of React Hooks with React 16.8 in February 2019 allowed developers to manage state and lifecycle behaviors within functional components, reducing the reliance on class components. This trend aligns with
4176-469: The separate fork of these apps for the Xbox 360 and for the versions they were developing for the mobile-based Windows CE environment became difficult to maintain. These complexities led Microsoft towards its "Windows Everywhere" approach c. 2010 , reviewing all the dependencies within the desktop, Xbox, and mobile versions of Windows atop the MinWin process and creating a CoreSystem that contained

This allows the choice of whichever libraries the developer prefers to accomplish tasks such as performing network access or local data storage. Common patterns of usage have emerged as the library matures. To support React's concept of unidirectional data flow (which might be contrasted with AngularJS 's bidirectional flow),
4320-416: The update supports 16:10 on VGA or HDMI, expanding the choice of resolutions. On September 22, 2010, Microsoft announced that the Xbox Live dashboard would be updated again. The new design, nicknamed the "Kinect" dashboard, would incorporate the Metro interface used in other Microsoft products, such as Zune HD and Windows Phone . As well as a new color scheme and other minor tweaks to the overall layout,
4392-544: The update would also include a "Kinect hub", designed specifically for the Kinect sensor for easier dashboard navigation. The update was released on November 1, 2010. At E3 2011 , it was announced that the dashboard would be updated once again to have the interface look even more like the Metro design in Windows 8 and Windows Phone 8, and to include the Bing search engine. Kinect would also be updated allowing users to navigate

This would prove troublesome for Microsoft from multiple directions. For the Xbox division, it made it difficult to bring in other Microsoft applications like Internet Explorer and Silverlight which had to be modified to work on the Xbox software. For Microsoft,
4608-666: Was a target goal for the newer consoles, and as such, these new consoles are fully backward compatible with all games in the Xbox One library with the exception of those requiring Kinect support. The supported list includes the Xbox and Xbox 360 games that were playable via emulation on the Xbox One. The original Xbox runs a custom operating system which is based on a heavily modified version of Windows 2000 , an approach that Microsoft engineer Don Box called "fork and run". It exports APIs similar to those found in Microsoft Windows , such as Direct3D . While Windows 2000

When loading a game, the operating system would unload itself to give all of the console's resources to the game, and then when the player left the game, the operating system would load back up again. Xbox Live support

On the release of the Xbox One in 2014, the program was renamed to Xbox Preview Program, and Microsoft made this program open to all rather than restricting through invitation. Later in November 2016 rebranded to the Xbox Insider Program, corresponding to the similar Windows Insider program for those testing its computer operating system. With

In May 2013, at JSConf US, the project was officially open-sourced, marking a significant turning point in its adoption and growth. 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. On April 18, 2017, Facebook announced React Fiber,

A similar emulator was developed and released in October 2017 for the Xbox One for a limited selection of original Xbox console games. Achieving Xbox One-backward compatibility on the Xbox Series X and Series S
4968-513: Was not originally part of the system software as shipped in 2001, but added later in November 2002. While the Xbox was still being supported by Microsoft, the Xbox Dashboard was updated via Live several times to reduce cheating and add features. Microsoft released a dynamic background for its current Xbox Series X/S system software in May 2021 that is based on the original Xbox system software appearance. The original Xbox operating system source code

The Xbox System Software contains a heavily modified Hyper-V hypervisor (known as NanoVisor) as its host OS and two partitions. One of the partitions, the "Exclusive" partition is a custom virtual machine (VM) for games; the other partition, the "Shared" partition is a custom VM for running multiple apps including
5112-447: Was released to the public, introducing React Hooks. Hooks are functions that let developers "hook into" React state and lifecycle features from function components. Notably, Hooks do not work inside classes — they let developers use more features of React without classes. React provides several built-in hooks such as useState , useContext , useReducer , useMemo and useEffect . Others are documented in
5184-429: Was released to the public. 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 March 29, 2022, React 18 was released which introduced a new concurrent renderer, automatic batching and support for server side rendering with Suspense. The initial public release of React in May 2013 used
