RxJS is a library for reactive programming using Observables, making it easier to compose asynchronous and event-based programs. It provides core types like Observable, Observer, and various operators to manipulate data streams. Used extensively in frameworks like Angular, RxJS simplifies handling complex data flows and side effects, offering tools for data transformation, error handling, and backpressure management. It enables developers to write cleaner, more manageable code by abstracting away the complexities of asynchronous operations.
RxJS releases were most frequent in 2017 and 2018, with multiple versions each month. After 2018, the frequency decreased, with several months having no releases. Version 7 emerged in April 2021, followed by sporadic updates. Releases became less consistent after 2022, with only one release in February 2025 and no releases in the months following through September 3, 2025.
RxJS downloads show a generally upward trend from March 2024 to August 2025, peaking in June and July 2025. There's a noticeable surge starting in March 2025. September 2025 data is incomplete at 19,577,280 downloads, much lower than previous months.
