Extending Context

There is a request to extend Context. Discussed at #410 and https://github.com/honojs/honojs.dev/pull/1 The possibility of adding c.afunction() by the middleware is a good feature, I think.

But I don’t have any idea to implement it. One idea is using declare module:

declare module 'hono' {
   interface Context {
     afunction()
   }
 }

It seems to be not smart. Is there someone have other ideas?

And, also we want to implement adding “function” to Context, such as c.afunction().

I would like this ability, but mostly because I would like to add something like a ctx.auth() or ctx.trace().

That said, I’m fine creating a helper like getAuth(ctx) or getTrace(ctx) that uses get/set under the covers.

Hi @usualoma !

I believe the following is often the good pattern for users

Agree. I think it would be easier for users to understand if there is an explicit method. So, the author of the middleware should provide a method like “validatoResult” if wants to get some values from Context.

Though we have this guideline, feature #429 is good for us. I’ll merge it.
