​​Solving micro-frontend challenges with Module Federation

Proper system architecture is essential for the success of modern software companies, and one effective approach is using micro-frontends to break down monolithic frontend applications into smaller, manageable parts. webpack Module Federation, introduced in webpack 5, is a tool that facilitates this by allowing independent applications to share code and dependencies dynamically during runtime, reducing duplication and providing flexibility. It introduces the concepts of host and remote applications, where the host consumes modules exposed by the remote. Module Federation is closely associated with micro-frontends but can be used independently in monolithic applications to share design systems or dynamically load features. It plays a crucial role in reducing code duplication and updating shared modules across applications, although it presents challenges such as styling conflicts, dependency version mismatches, and routing conflicts. These can be addressed with strategies like using Tailwind CSS's prefix option, enforcing consistent dependency versions, and implementing distinct route namespaces. Module Federation simplifies the sharing of resources across applications, improving performance and ensuring consistent behavior in micro-frontends.
