This is the only case for Module Worker mode. If you want to use Variables or Secret Variables in Middleware, for example, "username" or "password" in Basic Authentication Middleware, you need to write like the following.
import { basicAuth } from 'hono/basic-auth'
type Bindings = {
USERNAME: string
PASSWORD: string
}
const app = new Hono<{ Bindings: Bindings }>()
//...
app.use('/auth/*', async (c, next) => {
const auth = basicAuth({
username: c.env.USERNAME,
password: c.env.PASSWORD,
})
return auth(c, next)
})
The same is applied to Bearer Authentication Middleware, JWT Authentication, or others.
