# ReactiveExtensions* - **Website:** - **Primary alias:** `reactivex.io` ## Description ReactiveX is an API for asynchronous programming with observable streams. It combines the best ideas from the Observer pattern, the Iterator pattern, and functional programming, making it the Observer pattern done right. With ReactiveX, you can easily create event streams or data streams, compose and transform streams with query-like operators, and subscribe to any observable stream to perform side effects. It is designed to be ubiquitous, meaning it can be used in frontend development with RxJS on the web or with Rx.NET and RxJava on mobile, as well as in backend development with a wide range of languages. By embracing ReactiveX's asynchronicity, you can achieve better codebases, avoid stateful programs, and handle async errors and concurrency effortlessly. ReactiveX is not just an API, it's an idea and a breakthrough in programming that has inspired other APIs, frameworks, and programming languages. ## Industries - 🖥 Computers Electronics and Technology - 🖥 Computers Electronics and Technology _(under Computers Electronics and Technology)_ - 🖥 Programming and Developer Software _(under Computers Electronics and Technology)_ - 📊 Business and Consumer Services - 🖥 Computer Hardware _(under Computers Electronics and Technology)_ ## Links - [github](https://github.com/ReactiveX) - [twitter](https://twitter.com/ReactiveX) - [facebook](https://facebook.com/ReactiveX-587919348043998) ## Logos & icons - icon _(primary)_ — PNG — [download](https://cdn.brandfetch.io/idn5Dklsrx/w/400/h/400/theme/dark/icon.png?c=1bxid64Mup7aczewSAYMX&t=1779086977904) - logo _(primary)_ — PNG — [download](https://cdn.brandfetch.io/idn5Dklsrx/w/80/h/75/theme/dark/logo.png?c=1bxid64Mup7aczewSAYMX&t=1769361200510) ## Colors | Name | Hex | Theme | | --- | --- | --- | | Mine Shaft | #333333 | dark | | Light Orchid | #e09cce | light | | Rose | #ff0090 | accent | ## Fonts - Signika — asset _(google)_ - Helvetica Neue — asset _(custom)_ ## Imagery - banner _(primary)_ — PNG — [download](https://cdn.brandfetch.io/idn5Dklsrx/w/1500/h/500/idPM35bXhz.png?c=1bxid64Mup7aczewSAYMX&t=1779086978210) --- _Source: _ _See [/llms.txt](/llms.txt) for a full list of agent-readable pages, and [/auth.md](/auth.md) for how agents authenticate._
