* `mount()` allows you to mount applications built with other frameworks into your Hono application.
|
|
*
|
|
* @see {@link https://hono.dev/docs/api/hono#mount}
|
|
*
|
|
* @param {Function} applicationHandler - other Request Handler
|
|
* @param {MountOptions} [options] - options of `mount()`
|
|
* @returns {MiddlewareHandler} handler to register with `app.all()`
|
|
*
|
|
* @example
|
|
* ```ts
|
|
* import { Router as IttyRouter } from 'itty-router'
|
|
* import { Hono } from 'hono'
|
|
* import { mount } from 'hono/mount'
|
|
* // Create itty-router application
|
|
* const ittyRouter = IttyRouter()
|
|
* // GET /itty-router/hello
|
|
* ittyRouter.get('/hello', () => new Response('Hello from itty-router'))
|
|
*
|
|
* const app = new Hono()
|
|
* app.all('/itty-router/*', mount(ittyRouter.handle))
|
|
* ```
|
|
*
|
|
* @example
|
|
* ```ts
|
|
* const app = new Hono()
|
|
* // Send the request to another application without modification.
|
|
* app.all('/app/*', mount(anotherApp, {
|
|
* replaceRequest: (req) => req,
