Waiting for #route() to complete

You may wish to wait for when the routing is complete.

In HaSeul 1.2.0 or above, a new done() function is available to tell the router when you have finished processing. This is different to the next() function, as done() does not carry on to the next suitable router/middleware, whereas next() does.

router
  .command('hello', ({ content, done }) => {
    // Process content
    done();
  })
  .command('mei', ({ content, next, done }) => {
    // Errors produced by the fetch function is passed into the `next` function.
    // When processing is complete, run the `done` function.
    fetch('http://example.com/')
      .then(data => data.text())
      .then(data => {
        console.log(data);
        done();
      })
      .catch(error => next(error))
  })

By calling the done() function, the router.route() function can reliably return a Promise which will always resolve whenever you tell HaSeul that your processing is complete.

router.route('meimei')
  .then(() => {
    // The routing has been complete
  })
