v4.13.13

Mount Middleware

app.mount() is now available as the Mount Middleware, hono/mount. It is just a handler, so you register it with app.all():

import { Router as IttyRouter } from 'itty-router'
import { Hono } from 'hono'
import { mount } from 'hono/mount'

const ittyRouter = IttyRouter()
ittyRouter.get('/hello', () => new Response('Hello from itty-router'))

const app = new Hono()
app.all('/itty-router/*', mount(ittyRouter.handle))

app.mount() still works in v4 but is deprecated and will be removed in v5. Migrating is a one-line change:

- app.mount('/itty-router', ittyRouter.handle)
+ app.all('/itty-router/*', mount(ittyRouter.handle))
