Handling 404?

[coelho]

I can't really seem to find a way to handle 404 Not Found with this router.

I tried this but ...

this.Handle("{404}", this.InitialView)
	this.Handle("{404}/{404}", this.InitialView)
	this.Handle("{404}/{404}/{404}", this.InitialView)

It's pretty obviously wrong.

Any tips or is this unsupported?

@coelho this isn't something I considered, and I'm not sure if this is something a client-side library should handle. I had imagined 404 Not Found responses are better handled by the server.

Still, I'm open to it. Can you provide some more context about why you would want this feature?

@albrow Sure. Sorry for the late reply on this one.

Basically, I'm developing a one-page app using Vecty where NGINX is forwarding all the URLs in / to index.html so I can make things like:
/
/user
/user/signin
/user/signup

This router is used on the client to see what page they are going to. If however the client received a malformed link: /user/signupnotalink for example, I wanted to be able to detect the 404 and either show a 404 page, or redirect them back to /, client-side.

Does that make sense?

EDIT: Code looks a little like this right now:

func (this *app) Init() {
	routes.HandleFunc("", this.InitialView)
	routes.HandleFunc("{404}", this.InitialView)
	routes.HandleFunc("{404}/{404}", this.InitialView)
	routes.HandleFunc("{404}/{404}/{404}", this.InitialView)
}

func (this *app) InitialView(context *router.Context) {
	this.InitialSigninRoute()
}

Would prefer it looks something like this:

func (this *app) Init() {
	routes.HandleFunc("", this.InitialView)
	routes.HandleNotFoundFunc(this.InitialView)
}

func (this *app) InitialView(context *router.Context) {
	this.InitialSigninRoute()
}
