Ability to use function inside handler.

[ppot]

For auth purpose It would be good to be able to pass function to our handler.

This way you can use: get('/account', auth(account)) instead of

module.exports = async (req, res) => {
   await auth(req)
 }

You can create a Higher Order Function for that.

const { send } = require('micro')
const { router, get } = require('microrouter')
const auth = require('../auth-from-somewhere');

const withAuth = (route) => 
  async (req, res) => {
    try {
      await auth(req);
      return route(req, res);
    } catch(e) {
      send(res, 401, 'Ńot allowed');
    }
  };

const hello = (req, res) => send(res, 200, `Hello ${req.params.who}`)
const notfound = (req, res) => send(res, 404, 'Not found route')

module.exports = router(
  get('/hello/:who', withAuth(hello)), 
  get('/*', notfound)
)
