You can access the Request ID through the requestId variable in the handlers and middleware to which the Request ID Middleware is applied.
const app = new Hono()
app.use('*', requestId())
app.get('/', (c) => {
return c.text(`Your request id is ${c.get('requestId')}`)
})
If you want to explicitly specify the type, import RequestIdVariables and pass it in the generics of new Hono().
import type { RequestIdVariables } from 'hono/request-id'
const app = new Hono<{
Variables: RequestIdVariables
}>()
