Extending Nginx with njs and Modules: Three Approaches Explained

In this installment of the Nginx Advanced series, we explore three distinct paths for extending Nginx's functionality: using njs (Nginx JavaScript), dynamic modules via load_module, and compiling custom modules. The video walks through each approach, starting with njs—a JavaScript runtime integrated into Nginx that allows scripting within the configuration. Next, dynamic modules are demonstrated, with a focus on GeoIP2, showing how to load modules at runtime without recompilation. Finally, the comparison section helps decide which path suits different use cases, and a production-ready configuration is provided. This lesson is part of the Nginx Advanced Mastery series, designed for IT professionals seeking deep technical knowledge.
