How to overwrite or remap one directory to another

Is it possible to “remap” a directory to another using polka and sirv?

I created a repository to test the following code:

// index.js
const polka = require('polka');
const sirv  = require('sirv');

const { PORT=3000 } = process.env;

polka()
  // Make "localhost:3000/components" to serve content from "public/compiled_components"
  .use('components', sirv('public/compiled_components'))

  // And everything else remains the same, on "public"
  .use(sirv('public'))

  .listen(PORT, err => {
    if (err) throw err;
    console.log(`Running on localhost:${PORT}`);
  });

My project has the following structure:

project
│   index.js
│
└───public
│   │
│   └───components (non compiled components)
│       │   component1.txt
│       │   component2.txt
│       │   ...
│   └───compiled_components (automatic compiled components, during development time)
│       │   component1.txt
│       │   component2.txt
│       │   ...

But, on the path localhost:3000/components, instead of serving the content of public/compiled_components it is still serving the content of public/components

Great! The last sample will only work in the next version of Polka. The reason it isn’t currently working is because stable polka is running use() before use(‘/foo’)

Thanks a lot!
