End the coroutine before ending the HTTP service

[myuid]

I started several coroutines before http.listenandserve to monitor files and synchronize data, need to close coroutines before stopping chi, do not know how to handle, please give me some suggestions or demo.

Take a look at graceful http server shutdown:
https://golang.org/pkg/net/http/#Server.Shutdown

Other than that, this is very general question and doesn't really belong to chi.

Thank you. I'm reference https://github.com/go-chi/chi/blob/master/_examples/graceful/main.go solves this problem.

Also, take a look at the resources mentioned in #627 (comment)

At a high level, you'll need to pass a ctx down to your implementation, potentially wait for work to complete/timeout and then call Shutdown on your http server.

Do check those resources though, there are code examples for you to build on.

hey gents, I realized the _examples/graceful example was quite outdated. I made a new one here https://github.com/go-chi/chi/blob/master/_examples/graceful/main.go which is simpler and doesn't use the go-chi/valve package and instead relies on just "context" signaling and http Shutdown method.
