ngrok

ngrok is a Node.js wrapper for the ngrok tunneling client, allowing developers to expose local services to the internet directly from JavaScript or the command line. It is commonly used for webhook testing, local API demos, development previews, and temporary public access to local applications. 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.
