ngrok-javascript is a native and idiomatic support for adding secure ingress directly into JavaScript and TypeScript applications, allowing developers to deliver services on the internet without managing low-level network primitives. It provides a single line of code solution that enables high performance, security, and resilience for apps without requiring additional effort or expertise in building it. The ngrok-javascript SDK is designed to integrate seamlessly into the JavaScript ecosystem, providing easy installation, integration, one-line usage, idiomatic functional options, built-in forwarding, and out-of-the-box logging support. It also enables developers to define ingress policies at a higher level of abstraction, eliminating the need to deal with low-level intricacies, making it environment-independent and simplifying distribution and management.
