equivalent of express .res.locals

[ahmafi]

Are set/get methods equivalent of express .res.locals?

I want to share something from a middleware to another middleware or next() route function.

Hi @ahmafi

The answer is probably yes. Try this:

type Variables = {
  message: string
}

const app = new Hono<{ Variables: Variables }>()

app.use('*', async (c, next) => {
  c.set('message', 'This is a message')
  await next()
})

app.get('/', (c) => {
  const message = c.get('message')
  return c.text(message) // Hello!
})

Great. So these are set per request and then they are deleted, right?

Hi @ahmafi !

Yes, per request.
