Better Router grouping.

[Ray-D-Song]

What is the feature you are proposing?

const book = new Hono()

book.get('/', (c) => c.text('List Books')) // GET /book
book.get('/:id', (c) => {
  // GET /book/:id
  const id = c.req.param('id')
  return c.text('Get Book: ' + id)
})
book.post('/', (c) => c.text('Create Book')) // POST /book

const app = new Hono()
app.route('/book', book)

The current routing grouping for running multiple Hono initialization methods is not very intuitive. I think we can attach a group method to the instance and return child instance, like this:

const app = new Hono()
const bookStore = app.group('/book_store')

bookStore.get('/:id', (c) => {
  const id = c.req.param('id')
  return c.text('Get Book Store: ' + id)
})

const book = bookStore.group('/book')
...

You just described basePath 😁

Yeah, I know basePath can achieve the same thing, I just think this is a more semantically organized way.

It will work if I change group() to basePath() from the code you suggested.

const app = new Hono()
- const bookStore = app.group('/book_store')
+ const bookStore = app.basePath('/book_store')
bookStore.get('/:id', (c) => {
  const id = c.req.param('id')
  return c.text('Get Book Store: ' + id)
})

- const book = bookStore.group('/book')
+ const book = bookStore.basePath('/book')
