Iframe Based Micro Frontends
Iframe Based Micro Frontends is an architectural approach for building web applications where independent, self-contained frontend modules (micro frontends) are integrated into a host application using HTML iframes. This technique leverages the native isolation and sandboxing properties of iframes to ensure that each micro frontend runs in its own separate execution context, preventing CSS and JavaScript conflicts. It enables teams to develop, deploy, and scale frontend components independently, often using different technologies or frameworks within the same application.
Developers should use Iframe Based Micro Frontends when they need to integrate legacy systems or third-party applications without refactoring, as iframes provide strong isolation that avoids style and script collisions. It is particularly useful in large organizations where multiple teams work on distinct parts of a web app, allowing for independent development cycles and technology choices. However, it is best suited for scenarios where communication between micro frontends is minimal, as iframe-based communication can be complex and may impact performance due to overhead.
