createMiddleware() is shortcut of factory.createMiddleware().
This function will create your custom middleware.
const messageMiddleware = createMiddleware(async (c, next) => {
await next()
c.res.headers.set('X-Message', 'Good morning!')
})
Tip: If you want to get an argument like message, you can create it as a function like the following.
const messageMiddleware = (message: string) => {
return createMiddleware(async (c, next) => {
await next()
c.res.headers.set('X-Message', message)
})
}
app.use(messageMiddleware('Good evening!'))
