improve documentation about loading the public folder and read posts requests

First of all a big thank you for Polka 💯 is always nice to have some diversity in the node ecosystem and this is really nice.

I think the documentation could use some improvements on how to load a /public folder. I appreciate that there is an example to use serve-static (https://github.com/lukeed/polka/blob/master/examples/with-serve-static/index.js) but I just can’t figure out how would you load e.g. a CSS file? I did try it and didn’t work for me.

So I did write this which I assume to be not the right way to do things but it works.

app.get('/public/:file', (req, res) => {

    console.log(req.params);
    if (fs.existsSync('./public/' + req.params.file)) {

        var file = fs.readFileSync('./public/' + req.params.file, 'utf8');
        res.write(file);
        res.end();

    } else {
        res.writeHead(200, {
            "Content-Type": "text/html; charset=utf-8"
        });
        res.write("⚽⚽⚽⚽ 404 - not found ⚽⚽⚽⚽");
        console.log(req);
        res.end('error')
        console.log(req.params);

    }

});

would serve-static provide a better approach to this ?

I believe that at least two elements have to be very clear in the readme/docs (without having to dig through all the example) a) how to parse post requests e.g. the current example just deal with JSON but I figured it out how to do it for forms too

app.use (bodyParser.urlencoded({ extended: true }));

b) how to load a public folder c) how to use templates (thanks to the good soul that provided polka-ejs!)

I understand that most people will use polka as a backend/API but why capture the rest of the audience too ? 😃 with EJS all is working very fine!

Does polka have built-in method to send html file? Something similar in express:

app.get("/contact", (req, res) => {
  return res.sendFile(path.join(__dirname, "../landing_page/contact.html"));
});
