This is a Webpack loader that simplifies lazy loading of Angular 2 modules by automatically transforming `loadChildren` path strings into proper `require` calls, handling both JiT and AoT compilation contexts. It's designed for Angular 2 developers using Webpack who need to implement lazy loading in their applications without manually managing the differences between JiT and AoT module loading. The loader is particularly useful for applications with complex routing structures that need to load feature modules on-demand.
