...The package can start HTTP, TCP, and TLS tunnels, with options for ports, regions, authentication tokens, basic authentication, custom configuration paths, and logging callbacks. It also exposes a wrapper around ngrok’s local client API, letting applications list tunnels, start or stop tunnels, inspect requests, replay requests, and clear request history. The module can be installed locally for application-level use or globally for CLI-style tunneling. Overall, it gives Node.js projects a convenient programmable interface for managing ngrok sessions.
