[VERY EXTREMELY CURSED] How can I access process.env (at start time)

You can try this syntax:

app.use('/auth/*', async (c, next) => {
  const mw = jwt({
    secret: c.env.JWT_SECRET
  })
  return await mw(c, next)
})

app.use('/auth/*', async (c, next) => {
  const mw = jwt({
    secret: c.env.JWT_SECRET
  })
  return await mw(c, next)
})

Service pattern with Hono.js

Sorry for confusing! new Hono() is called once outside the fetch() as you mentioned. But the middleware that is defined in the factory is called everytime:

app.use((c) => {
  const client = initClient(c.env.TOKEN)
  c.set('client', client)
})

app.use((c) => {
  const client = initClient(c.env.TOKEN)
  c.set('client', client)
})

So you are right!

Service pattern with Hono.js

As a syntax, one app would cover every route as you imagine. But, actually, the app will be created per request.

Service pattern with Hono.js

Hi @flow Indeed, you have to create the engine instance per route in the Cloudflare environment. Then, you can use a simple factory method to do it like the following:

import { Hono } from 'hono'

type Env = {
  Bindings: {
    TOKEN: string
  }
  Variables: {
    client: Client
  }
}

export const createAppWithDB = () => {
  const app = new Hono<Env>()
  app.use((c) => {
    const client = initClient(c.env.TOKEN)
    c.set('client', client)
  })
  return app
}

import { Hono } from 'hono'

type Env = {
  Bindings: {
    TOKEN: string
  }
  Variables: {
    client: Client
  }
}

export const createAppWithDB = () => {
  const app = new Hono<Env>()
  app.use((c) => {
    const client = initClient(c.env.TOKEN)
    c.set('client', client)
  })
  return app
}

Then you can use it in your routes:

const app = createAppWithDB()

app.post('/api', (c) => {
  c.var.client.put(/* */)
  // ...
})

const app = createAppWithDB()

app.post('/api', (c) => {
  c.var.client.put(/* */)
  // ...
})
