setResponseStatus

Nuxt provides composables and utilities for first-class server-side-rendering support.

You can use setResponseStatus to set the statusCode (and optionally the statusMessage) of the response.

setResponseStatus can only be called within component setup functions, plugins, and route middleware.

// Set the status code to 404 for a custom 404 page
setResponseStatus(404)

// Set the status message as well
setResponseStatus(404, 'Page Not Found')

::alert{icon=👉} In the browser, setResponseStatus will have no effect. ::
