runtime

Last updated April 30, 2026

The runtime option allows you to select the JavaScript runtime used for rendering your route.

layout.tsx | page.tsx | route.ts

export const runtime = 'nodejs'
// 'nodejs'

'nodejs' (default)
'edge' (deprecated)

Good to know:

The Edge Runtime is deprecated. Remove the runtime export from your route files. See Edge Runtime Deprecated.

This option cannot be used in Proxy.
