Fasthttp Gorilla WebSocket
The Gorilla WebSocket package provides a complete and tested implementation of the WebSocket protocol. The package API is stable.
go get github.com/fasthttp/websocket
But beware that this will fetch the latest commit of the master branch which is never purposely broken, but usually not considered stable anyway.
If you're using dep, just use
dep ensure to add
a specific version of fasthttp/websocket including all its transitive dependencies to
dep ensure -add firstname.lastname@example.org
IMPORTANT: dep is only supported until version v1.4.0. In future versions will use Go modules.

- Large messages are fragmented in Chrome's new WebSocket implementation.
- The application can get the type of a received data message by implementing a codec marshal function.
- The go/net
io.Writeroperate across WebSocket frame boundaries. Read returns when the input buffer is full or a frame boundary is encountered. Each call to Write sends a single frame message. The Gorilla
io.WriteCloseroperate on a single WebSocket message.
