How to use path prefix with sirv?

Thanks for great work. I am trying to use sirv with Polka and Sapper.

I have my public assets in folder ‘public’ and I want to reference those assets with path prefix say public/images/hero.jpg.

When I use Sirv as app.use(sirv('public')), I need to refer static assets as images/hero.jpg. I am basically looking for something like app.use('/static', express.static(path.join(__dirname, 'public'))).

Hey, thanks~!

The current combination of Polka & Sapper doesn’t really allow for this right now, unless you do this:

// create the middleware early
//~> so that you don't recreate every time
const assets = sirv('public');

polka()
  .use(
    compression(),
    // ...
    (req, res, next) => {
      // check if we're looking at a /static/* request
      return req.path.startsWith('/static/') ? assets(req, res, next) : next();
    },
    // ...
    sapper({ manifest })
  )

A few others have had this request a few times, so I’ve opened a PR (https://github.com/sveltejs/sapper/pull/326) on Sapper to make this easier for Polka users. Hopefully it aligns with their goals, otherwise the above will do the trick for you 😃

Without Sapper, using sirv with Polka operates as you’d expect:

polka()
  .use('/static', sirv('public'))
  // ...

GREAT SUCCESS! 💯

You are awesome. I can’t thank you enough. More than the solution I am grateful for goodwill. This has been very inspiring.
