Global HTTP & HTTPS Tunneling

global-tunnel-ng is a utility that globally configures Node.js's built-in `http` and `https` agents to route all outgoing network traffic through an upstream HTTP proxy. It works transparently for modules that utilize Node's default `http.request()` method and popular libraries like `request`. The current stable version is 2.7.1, published in November 2018. The package focuses on transparent global proxying, allowing developers to set a proxy once for an entire application without modifying individual HTTP client calls. It supports both `CONNECT` tunneling for HTTPS (and optionally HTTP) and absolute-URI request methods, accommodating various proxy configurations. Its primary differentiator is its low-level global interception of Node.js's native networking stack. For modern Node.js versions (v10+), `global-agent` is often recommended as a more actively maintained alternative.
