  title: NGINX njs Scripting Connections HTTP Keyvals API
  version: '0.8'
  description: The NGINX njs module provides a JavaScript runtime embedded inside NGINX. It does not expose HTTP endpoints itself. Instead, it offers scripting objects (HTTP request, stream session, Fetch API, etc.) that are available within njs handler functions configured in the NGINX configuration file. This specification documents the key njs objects as OpenAPI schemas only; the paths object is intentionally empty because there are no REST endpoints to describe.
