+## Nuxt 4
+
+If you want to use it in nuxt 4 you can define a nitro plugin with an other hook
+
+`server/plugins/compression.ts`
+````ts
+import { useCompression } from 'h3-compression'
+
+export default defineNitroPlugin((nitro) => {
+	nitro.hooks.hook('beforeResponse', async (event, res) => {
+		// Skip internal nuxt routes (e.g. error page)
+		if (getRequestURL(event).pathname.startsWith('/_nuxt')) return
+
+		const header = getResponseHeader(event, 'content-type')
+		const values = Array.isArray(header) ? header : [header]
+		const compress = values.find(t => typeof t === 'string' && t.includes('text/html'))
+
+		if (!compress) return
+
+		await useCompression(event, res)
+	})
+})
+````
+> [!NOTE]  
+> `useCompressionStream` doesn't work right now in nitro. So you just can use `useCompression`

 ## Utilities
 
 H3-compression has a concept of composable utilities that accept `event` (from `eventHandler((event) => {})`) as their first argument and `response` as their second.
