Allow serving pre-compressed files with serveStatic

[inetol]

What is the feature you are proposing?

Adding an option to prioritize pre-compressed files with .br, .zst or .gz extensions and in case they do not exist serve the file as usual. When compressing the assets of a web page in CI, this would help to reduce the server load by avoiding the need to use compress middleware.

You can use rewriteRequestPath option in serveStatic middleware for this task. Check it out here - https://hono.dev/docs/getting-started/nodejs#serve-static-files

I tried to use it before but it does not expose the request/response context, so I cannot set the necessary headers nor do the logic to check if the client is accepting compressed files.

So, will it be better if the API passes context as the next param? like this -

serveStatic({
  root: './',
  rewriteRequestPath: (path, c) =>
    path.replace(/^\/static/, '/statics'),
})

And also with the new API coming (https://x.com/yusukebe/status/1829780618626146513) it will get much easier
