What was Module Federation used for?

Module Federation is used for dynamic sharing of modules between different frontend applications or parts of the same application. It allows:

• Loading and using components or libraries from other builds at runtime, without the need to rebuild the entire project.
• Sharing code between teams so that each can develop their module independently.
• Improving load times through lazy loading of necessary parts.

For example, in a monorepo with multiple micro-frontends, we used Module Federation so that one service could dynamically load components from another, simplifying scaling and updating individual parts of the interface without a full deployment of the entire application.
