Module Federation
Module Federation is a webpack feature that enables dynamic code sharing between separate JavaScript applications at runtime. It allows applications to load code from other builds or remote sources, facilitating micro-frontend architectures and code reuse across projects. This approach helps in building scalable, independently deployable frontend applications.
Developers should learn Module Federation when building micro-frontends, as it allows teams to work on independent applications that can share components and dependencies without tight coupling. It is particularly useful in large-scale enterprise applications where different teams need to deploy features independently while maintaining a cohesive user experience. Use cases include shared UI libraries, cross-application state management, and incremental upgrades of legacy systems.
