URL redirect && `dispatch` to return promise

I am trying to think of a way to do redirection. Here are some examples, of which one requires dispatch to return promise.

// Redirect / to /home
{on("/", async() => {
     const {state, component} = await this.dispatch("/home");
     return component;
})}

Or provide a new api redirect (same level as on)?

redirct("/", "/home");

Apparently second one is better. Maybe adding this will be good?

What do you think about this API? Where a route with redirect looks like this:

const router = new Router()
  .route('/', ({ redirect }) => redirect('/home'));

Another example, when you need to do some async stuff before doing a redirect:

const router = new Router()
  .router('/p/:id', async action({ redirect }, { id }) {
    const url = `/graphql?query={post(id:"${id}"){slug,author{username}}}`;
    const resp = await fetch(url, { method: 'post' });
    const { data } = await resp.json();
    if (data.post) {
      redirect(`/${data.post.author.username}/${data.post.slug}`);
    }
  });
