jsemu - A list of emulators written in the JavaScript programming language

A list of emulators written in the JavaScript programming language.This list started as a compilation of JavaScript emulators posted to Echo JS over the years. If you know about any missing emulators, please consider adding them to the collection: the source for this page is available on GitHub. Thank you in advance.

sass.js - Sass.js - API for emscripted libsass to run in the browser

•    Javascript

Sass parser in JavaScript. Have a look at the Interactive Playground to play around with compiling SCSS to CSS in your browser.This is a convenience API for emscripted libsass (at v3.4.8). If you're looking to run Sass in node, you're probably looking for node-sass. Sass.js and node-sass should generate the same results.

sql.js - SQLite compiled to JavaScript through Emscripten

•    Javascript

sql.js is a port of SQLite to JavaScript, by compiling the SQLite C code with Emscripten. It uses a virtual database file stored in memory, and thus doesn't persist the changes made to the database. However, it allows you to import any existing sqlite file, and to export the created database as a javascript typed array. There is no C bindings or node-gyp compilation here, sql.js is a simple javascript file, that can be used like any traditional javascript library. If you are building a native application in javascript (using Electron for instance), or are working in node.js, you will likely prefer to use a native binding of SQLite to javascript.

videoconverter.js - Convert videos in your browser

•    Javascript

videoconverter.js is a library that allows you to convert and manipulate videos inside of your web browser. This is achieved by converting the popular FFmpeg library into JavaScript, using Emscripten.

openFrameworks - openFrameworks is a community-developed cross platform toolkit for creative coding in C++

•    C++

docs has some documentation around OF usage, per platform things to consider, etc. You should definitely take a look in there; for example, if you are on OSX, read the osx.md. apps and examples are where projects go -- examples contains a variety of projects that show you how to use OF, and apps is where your own projects will go. libs contains the libraries that OF uses, including the openframeworks core itself. addons are for additional functionality that's not part of the core. export is for DLLs and dylibs that need to be put in each compiled project. The scripts folder has the templates and small scripts for automating OF per platform. project generator is a GUI based tool for making new projects - this folder is only there in packaged releases. One idea that's important is that OF releases are designed to be self-contained. You can put them anywhere on your hard drive, but it's not possible to mix different releases of OF together, so please keep each release (0.8.0, 0.8.1) separate. Projects may generally work from release to release, but this is not guaranteed. Because OF is self-contained, there's extensive use of local file paths (ie, ../../../) throughout OF. It's important to be aware of how directories are structured. A common error is to take a project and move it so that it's a level below or above where it used to be compared to the root of OF. This means that links such as ../../../libs will break.

viz.js - A hack to put Graphviz on the web.

•    Javascript

This project builds Graphviz with Emscripten and provides a simple wrapper for using it in the browser. For more information, see the wiki.

bgfx - Cross-platform, graphics API agnostic, "Bring Your Own Engine/Framework" style rendering library

•    C++

Cross-platform, graphics API agnostic, "Bring Your Own Engine/Framework" style rendering library. http://airmech.com/ AirMech is a free-to-play futuristic action real-time strategy video game developed and published by Carbon Games.

instascan - HTML5 QR code scanner using your webcam

•    Javascript

Real-time webcam-driven HTML5 QR code scanner. Try the live demo. Note: Chrome requires HTTPS when using the WebRTC API. Any pages using this library should be served over HTTPS.

binaryen - Compiler infrastructure and toolchain library for WebAssembly, in C++

•    WebAssembly

Consult the contributing instructions if you're interested in participating. As a result, you might notice that round-trip conversions (wasm => Binaryen IR => wasm) change code a little in some corner cases.

stdweb - A standard library for the client-side Web

•    Rust

The goal of this crate is to provide Rust bindings to the Web APIs and to allow a high degree of interoperability between Rust and JavaScript.

yew - Rust framework for building client web apps

•    Rust

Yew is a modern Rust framework inspired by Elm and ReactJS for creating multi-threaded frontend apps with WebAssembly. NEW! The framework supports multi-threading & concurrency out of the box. It uses Web Workers API to spawn actors (agents) in separate threads and uses a local scheduler attached to a thread for concurrent tasks.

quiet-js - Transmit data with sound using Web Audio -- Javascript binding for libquiet

•    Javascript

This is a javascript binding for libquiet, a library for sending and receiving data via sound card. It can function either via speaker or cable (e.g., 3.5mm). Quiet comes included with a few transmissions profiles which configure quiet's transmitter and receiver. For speaker transmission, there is a profile which transmits around the 19kHz range, which is essentially imperceptible to people (nearly ultrasonic). For transmission via cable, quiet.js has profiles which offer speeds of at least 40 kbps. Try it out in this live example.

nbind - :sparkles: Magical headers that make your C++ library accessible from JavaScript :rocket:

•    C++

nbind is a set of headers that make your C++11 library accessible from JavaScript. With a single #include statement, your C++ compiler generates the necessary bindings without any additional tools. Your library is then usable as a Node.js addon or, if compiled to asm.js with Emscripten, directly in web pages without any plugins. nbind works with the autogypi dependency management tool, which sets up node-gyp to compile your library without needing any configuration (other than listing your source code file names).

lua.vm.js - The Lua VM, on the Web

•    C

The Lua VM, on the Web

pce - Emulates Mac Plus, PC, & Atari ST in asm.js

•    C

PCE.js runs classic computers in the browser. It's a port of Hampa Hug's excellent PCE emulator, put together by James Friend. PCE.js currently emulates Mac Plus, IBM PC/XT and Atari ST functionally in recent versions of Chrome and Firefox.

miniaudio - Single file audio playback and capture library written in C.

•    C

miniaudio (formerly mini_al) is a single file library for audio playback and capture. It's written in C89 (compilable as C++) and released into the public domain. Then just compile. There's no need to install any dependencies. On Windows and macOS there's no need to link to anything. On Linux and BSD, just link to -lpthread, -lm and -ldl.

ffmpeg.js - Port of FFmpeg with Emscripten

•    Javascript

This library provides FFmpeg builds ported to JavaScript using Emscripten project. Builds are optimized for in-browser use: minimal size for faster loading, asm.js, performance tunings, etc. Though they work in Node as well.Note: only NPM releases contain abovementioned files.

webm.js - JavaScript WebM encoder

•    Javascript

Create WebM videos in your browser. No server-side, pure JavaScript.Latest build of webm.js is available here. NOTE: built-in video player uses software decoding in order to play any video it can encode and thus experimental and slow.

cib - clang running in browser (wasm)

•    C++

clang running in browser (wasm)

ogv.js - JavaScript media player using Ogg/Vorbis/Theora/Opus/WebM libs compiled with Emscripten

•    Javascript

Media decoder and player for Ogg Vorbis/Opus/Theora and WebM video. Based around libogg, libvorbis, libtheora, libopus, libvpx, and libnestegg compiled to JavaScript with Emscripten.
