// the take
sockjs-go is a Go server-side implementation of the SockJS protocol, which emulates WebSockets with fallback transports (XHR polling, JSONP, htmlfile, eventsource) for browsers that can't do a real WebSocket handshake. It's for anyone maintaining an older real-time app built against sockjs-client, not something you'd reach for on a new project.
The README is unusually honest about protocol compliance — it lists the exact SockJS protocol tests it fails and explains why instead of just claiming full compatibility. The WebSocket transport is built on Gorilla's websocket package rather than a hand-rolled implementation, and there's real per-transport test coverage plus a benchmarks file, not just a smoke test.
Last commit is from November 2023 and the CI badge is still Travis CI, a service that effectively stopped being usable for open source around 2021 — nobody's kept the lights on here. The README actively maintains three different import paths (v1 deprecated, v2 via gopkg.in, v3 via go modules), which is confusing busywork for anyone just trying to add the dependency. More fundamentally, the problem SockJS was built to solve — browsers with no usable native WebSocket — doesn't really exist anymore, so this is solid engineering aimed at a compatibility problem that's aged out from under it.
We read the README, the directory tree and a key source file in October 2026. Nobody pays to be listed. How we judge →
