cone 🗼

The goal of cone is to provide an easy to use event handler implementation that can support a multitude of event backends.

Usage

// Configure handlersh:=cone.NewHandlerMux()
h.HandleFunc("event.subject", func(r cone.Response, e*cone.Event) {
_=r.Ack()
})
h.HandleFunc("event.subject2", func(r cone.Response, e*cone.Event) {
_=r.Ack()
})
// Setup an event sources:=conetest.NewSource()
// Setup consumer with source and handlerc:=cone.New(s, h)
// Start consumer. Processes events from the source and calls your handler.c.ListenAndConsume()

Middleware

Middleware can be placed around a specific handler.

middleware:=func(next cone.Handler) cone.Handler {
returnfunc(r cone.Response, e*cone.Event) {
next.Serve(r, e)
}
}
varhandler cone.HandlerFunc=func(r cone.Response, e*cone.Event) {
_=r.Ack()
}
h:=cone.NewHandlerMux()
h.Handler("event.subject", middleware(handler))

Or the whole mux.

middleware:=func(next cone.Handler) cone.Handler {
returnfunc(r cone.Response, e*cone.Event) {
next.Serve(r, e)
}
}
s:=conetest.NewSource()
h:=cone.NewHandlerMux()
c:=cone.New(s, middleware(h))

Todo

• Event context
• Event headers
• Handler middleware
• Consumer subject wildcard event.*
