Summary
Get and set arbitrary key-value pairs, with a lifetime of the current request. This allows passing specific values between middleware or from middleware to route handlers. ```ts twoslash import { Hono } from 'hono' const app = new Hono (...
Content
Get and set arbitrary key-value pairs, with a lifetime of the current request. This allows passing specific values between middleware or from middleware to route handlers.
import { Hono } from 'hono'
const app = new Hono<{ Variables: { message: string } }>()
// ---cut---
app.use(async (c, next) => {
c.set('message', 'Hono is cool!!')
await next()
})
app.get('/', (c) => {
const message = c.get('message')
return c.text(`The message is "${message}"`)
})
Pass the Variables as Generics to the constructor of Hono to make it type-safe.
import { Hono } from 'hono'
// ---cut---
type Variables = {
message: string
}
const app = new Hono<{ Variables: Variables }>()
The value of c.set / c.get are retained only within the same request. They cannot be shared or persisted across different requests.
