 websocket is a minimal and idiomatic WebSocket library for Go.
 
-> **note**: I haven't been responsive for questions/reports on the issue tracker but I do
-> read through and there are no outstanding bugs. There are certainly some nice to haves
-> that I should merge in/figure out but nothing critical. I haven't given up on adding new
-> features and cleaning up the code further, just been busy. Should anything critical
-> arise, I will fix it.

   - Gorilla writes directly to a net.Conn and so duplicates features of net/http.Client.
 - Concurrent writes

+- [CloseRead](https://pkg.go.dev/nhooyr.io/websocket#Conn.CloseRead) helper for write only connections
 - Idiomatic [ping pong](https://pkg.go.dev/nhooyr.io/websocket#Conn.Ping) API
   - Gorilla requires registering a pong callback before sending a Ping
 - Can target Wasm ([gorilla/websocket#432](https://github.com/gorilla/websocket/issues/432))

   - Gorilla's implementation is slower and uses [unsafe](https://golang.org/pkg/unsafe/).
