Something as common and seemingly simple as a search bar needs to have various checks in place. ![]() You will also use HTML and CSS to format the search bar. In this tutorial, you will use RxJS to build a feature-rich search bar that returns real-time results to users. The community around RxJS has done this heavy lifting, and the result is an API that you can directly use in any application to write clean and maintainable code. This means that one could implement virtually every aspect of RxJS with nothing more than functions that receive a list of arguments and callbacks, and then execute them when signaled to do so. RxJS’s implementation is based on chained functions that are aware and capable of handling data over a range of time. RxJS is also widely used by libraries like Angular and React. ReactiveX, the umbrella under which RxJS lies, has its extensions in many other languages like Java, Python, C++, Swift, and Dart. RxJS is a popular library for reactive programming in JavaScript. This makes it a perfect fit for JavaScript as asynchronous data is common in the language. This includes keystrokes, HTTP requests, files to be printed, and even elements of an array, which can be considered to be timed over very small intervals. Reactive Programming is a paradigm concerned with asynchronous data streams, in which the programming model considers everything to be a stream of data spread over time.
