/**
|
|
* Method Not Allowed Middleware for Hono.
|
|
*
|
|
* Returns a `405 Method Not Allowed` response with an `Allow` header when the request path
|
|
* matches a registered route but the request method is not supported.
|
|
*
|
|
* @param {MethodNotAllowedOptions} options - The options for the middleware.
|
|
* @param {Hono} options.app - The Hono instance used by the application.
|
|
* @param {MethodNotAllowedHandler} [options.onMethodNotAllowed] - Generates the response, including its `Allow` header.
|
|
* @returns {MiddlewareHandler} The middleware handler function.
|
|
*
|
|
* @example
|
|
* ```ts
|
|
* const app = new Hono()
|
|
*
|
|
* app.use(methodNotAllowed({ app }))
|
|
*
|
|
* app.get('/hello', (c) => c.text('Hello!'))
|
|
* app.post('/hello', (c) => c.text('Posted!'))
|
|
*
|
|
* // PUT /hello -> 405 Method Not Allowed
|
|
* // Allow: GET, HEAD, POST
|
|
* ```
|
|
*
|
|
* @example
|
|
* ```ts
|
|
* app.use(
|
|
* methodNotAllowed({
|
|
* app,
|
|
* onMethodNotAllowed: (c, methods) =>
|
|
* c.json({ error: 'Method Not Allowed' }, 405, { Allow: methods.join(', ') }),
|
|
* })
|
|
* )
|
|
* ```
