BrowserQuest is a free massively multiplayer online role-playing game created by French developer Little Workshop and the Mozilla Foundation. [1] [2]
BrowserQuest is a demonstration of a number of modern web technologies. It is written for the web platform, utilizing WebSockets for multiplayer networking, and is playable from modern web browsers. The client makes use of canvas elements to render the graphics, web workers to initialize the map without affecting the rest of the page, localStorage to save progress, media queries to dynamically resize the game to the device, and HTML audio to render the sound. The server is written in JavaScript, and runs in Node.js. The server and browser communicate using WebSockets. [3]
Both BrowserQuest's client and server source code are available on GitHub. [2] Its code is licensed under MPL 2.0. Content is licensed under CC BY-SA 3.0. [4]
In BrowserQuest, players can interact with each other using the in-game chat system, or by working together to defeat enemies. [2] There are achievements available to unlock as one plays. Loot is dropped when players defeat the enemies, which can be picked up by any player. Loot includes the invincibility potion, which changes a player's outfit to appear like the Firefox logo, and various gear. At one point in time, the system recorded over 1,900 concurrent users playing at the same time. [5] [6] [7]
Gecko is a browser engine developed by Mozilla. It is used in the Firefox browser, the Thunderbird email client, and many other projects.
This article compares browser engines, especially actively-developed ones.
Google Native Client (NaCl) is a discontinued sandboxing technology for running either a subset of Intel x86, ARM, or MIPS native code, or a portable executable, in a sandbox. It allows safely running native code from a web browser, independent of the user operating system, allowing web apps to run at near-native speeds, which aligns with Google's plans for ChromeOS. It may also be used for securing browser plugins, and parts of other applications or full applications such as ZeroVM.
WebGL is a JavaScript API for rendering interactive 2D and 3D graphics within any compatible web browser without the use of plug-ins. WebGL is fully integrated with other web standards, allowing GPU-accelerated usage of physics, image processing, and effects in the HTML canvas. WebGL elements can be mixed with other HTML elements and composited with other parts of the page or page background.
WebSocket is a computer communications protocol, providing a simultaneous two-way communication channel over a single Transmission Control Protocol (TCP) connection. The WebSocket protocol was standardized by the IETF as RFC 6455 in 2011. The current specification allowing web applications to use this protocol is known as WebSockets. It is a living standard maintained by the WHATWG and a successor to The WebSocket API from the W3C.
Content Security Policy (CSP) is a computer security standard introduced to prevent cross-site scripting (XSS), clickjacking and other code injection attacks resulting from execution of malicious content in the trusted web page context. It is a Candidate Recommendation of the W3C working group on Web Application Security, widely supported by modern web browsers. CSP provides a standard method for website owners to declare approved origins of content that browsers should be allowed to load on that website—covered types are JavaScript, CSS, HTML frames, web workers, fonts, images, embeddable objects such as Java applets, ActiveX, audio and video files, and other HTML5 features.
HTML audio is a subject of the HTML specification, incorporating audio input, playback, and synthesis, all in the browser.
The Chromium Embedded Framework (CEF) is an open-source software framework for embedding a Chromium web browser within another application. This enables developers to add web browsing functionality to their application, as well as the ability to use HTML, CSS, and JavaScript to create the application's user interface.
Emscripten is an LLVM/Clang-based compiler that compiles C and C++ source code to WebAssembly, primarily for execution in web browsers.
Three.js is a cross-browser JavaScript library and application programming interface (API) used to create and display animated 3D computer graphics in a web browser using WebGL. The source code is hosted in a repository on GitHub.
The virtual world framework (VWF) is a means to connect robust 3D, immersive, entities with other entities, virtual worlds, content and users via web browsers. It provides the ability for client-server programs to be delivered in a lightweight manner via web browsers, and provides synchronization for multiple users to interact with common objects and environments. For example, using VWF, a developer can take video lesson plans, component objects and avatars and successfully insert them into an existing virtual or created landscape, interacting with the native objects and users via a VWF interface.
Mozilla is a free software community founded in 1998 by members of Netscape. The Mozilla community uses, develops, publishes and supports Mozilla products, thereby promoting exclusively free software and open standards, with only minor exceptions. The community is supported institutionally by the non-profit Mozilla Foundation and its tax-paying subsidiary, the Mozilla Corporation.
PDF.js is a JavaScript library that renders Portable Document Format (PDF) files using the web standards-compliant HTML5 Canvas. The project is led by the Mozilla Corporation after Andreas Gal launched it in 2011.
SignalR is a free and open-source software library for Microsoft ASP.NET that allows server code to send asynchronous notifications to client-side web applications. The library includes server-side and client-side JavaScript components.
asm.js is a subset of JavaScript designed to allow computer software written in languages such as C to be run as web applications while maintaining performance characteristics considerably better than standard JavaScript, which is the typical language used for such applications.
Media Source Extensions (MSE) is a W3C specification that allows JavaScript to send byte streams to media codecs within web browsers that support HTML video and audio. Among other possible uses, this allows the implementation of client-side prefetching and buffering code for streaming media entirely in JavaScript. It is compatible with, but should not be confused with, the Encrypted Media Extensions (EME) specification, and neither requires the use of the other, although many EME implementations are only capable of decrypting media data provided via MSE.
PlayCanvas is an open-source 3D game engine/interactive 3D application engine alongside a proprietary cloud-hosted creation platform that allows for simultaneous editing from multiple computers via a browser-based interface. It runs in modern browsers that support WebGL, including Mozilla Firefox and Google Chrome. The engine is capable of rigid-body physics simulation, handling three-dimensional audio and 3D animations.
OpenFL is a free and open-source software framework and platform for the creation of multi-platform applications and video games. OpenFL applications can be written in Haxe, JavaScript, or TypeScript, and may be published as standalone applications for several targets including iOS, Android, HTML5, Windows, macOS, Linux, WebAssembly, Flash, AIR, PlayStation 4, PlayStation 3, PlayStation Vita, Xbox One, Wii U, TiVo, Raspberry Pi, and Node.js.
Phaser is a 2D game framework used for making HTML5 games for desktop and mobile. It is free software developed by Photon Storm.
Blazor is a free and open-source web framework that enables developers to create web user interfaces (UI) based on components, using C# and HTML. It is being developed by Microsoft, as part of the ASP.NET Core web app framework.
