Support for Firebase Functions

[RobertSasak]

What is the feature you are proposing?

I think Deno is a perfect to be used as a dynamic router in Firebase functions. Currently Express is the main choise.

Firebase function expect (request, reponse)=>void function which should not be so difficult to provide from Deno. I have looked into nodejs-server implementaion but I might need some more hints.

It was not so hard in the end. Import node-server package and use getRequestListener around app.fetch.

import { getRequestListener } from '@hono/node-server'
import { onRequest } from 'firebase-functions/v2/https'
import { Hono } from 'hono'

const app = new Hono()
app.get('/**', (c) => c.text('Hello Node.js!'))

export const web = onRequest(getRequestListener(app.fetch))

There is an silent error 500 when doing a POST request with payload.

TypeError: Response body object should not be disturbed or locked

It is exactly the same error as in honojs/node-server#84

@RobertSasak

Could you create the issue on honojs/node-server issues with the minimal code for reproduce it?

[RobertSasak]

Yes, lets move conversation to #1695
