Summary
Hono has built-in middleware. ```ts import { Hono } from 'hono' import { poweredBy } from 'hono/powered-by' import { logger } from 'hono/logger' import { basicAuth } from 'hono/basic-auth' const app = new Hono() app.use(poweredBy()) app....
Content
Hono has built-in middleware.
import { Hono } from 'hono'
import { poweredBy } from 'hono/powered-by'
import { logger } from 'hono/logger'
import { basicAuth } from 'hono/basic-auth'
const app = new Hono()
app.use(poweredBy())
app.use(logger())
app.use(
'/auth/*',
basicAuth({
username: 'hono',
password: 'acoolproject',
})
)::: warning In Deno, it is possible to use a different version of middleware than the Hono version, but this can lead to bugs. For example, this code is not working because the version is different.
import { Hono } from 'jsr:@hono/hono@4.4.0'
import { upgradeWebSocket } from 'jsr:@hono/hono@4.4.5/deno'
const app = new Hono()
app.get(
'/ws',
upgradeWebSocket(() => ({
// ...
}))
):::
