sockjs-client is a browser JavaScript library that provides a WebSocket-like object. It enables cross-browser messaging and falls back to various browser-specific transports when WebSocket isn't available, ensuring reliable communication. SockJS presents a consistent programming interface over multiple protocols, simplifying real-time web application development by abstracting away the complexities of dealing with different browser WebSocket implementations or network conditions. It's a foundational piece for building robust and responsive web experiences.
SockJS-client's release frequency is sporadic. Initial releases occurred in 2012, followed by a period of inactivity until 2015. Releases peaked in July 2015 with three versions. After that releases were infrequent, with a few releases annually, and none since May 2022. The data indicates minimal, and inconsistent maintenance over the years.
Sockjs-client npm package downloads show variability. From February 2024 to August 2025, downloads peaked in March 2024 at 16 million. After a drop, the downloads generally stayed between 12 and 15 million, with a jump in June and July 2025 and a sharp drop in August 2025.
