How to deal with recovery middleware?

[Rick Lee]

You said Alice make no garentees with middleware's behaviors,
it will stop the chain when panic,
so how can I make recovery as a middleware?

[Justinas Stankevičius]

The net/http server will recover from panics automatically (see the relevant code).

However, if you'd like to roll out your own recovery middleware, it should kick in as early as possible in the request lifecycle. Ideally, it should be the first in the chain.

alice.New(recoveryMiddleware, ...).Then(handler)
