Communication between Micro Frontends
Solid interaction between Micro Frontends is a key that will help create a wholesome and consistent experience for users. Several techniques can be employed to facilitate communication:
- Custom Events:
- Micro frontends can communicate with each other using custom events dispatched through the browser’s native event system (e.g.,
CustomEvent
in JavaScript). - One micro frontend can dispatch an event with relevant data, and other micro frontends can listen for and respond to these events accordingly.
- Custom events provide a lightweight and flexible way to enable communication between micro frontends without tight coupling.
- Micro frontends can communicate with each other using custom events dispatched through the browser’s native event system (e.g.,
- Shared State Management:
- Micro frontends can share state by storing it in a shared location, such as a global state management solution or a centralized data store.
- State management libraries like Redux, MobX, or Vuex can be used to manage shared state across multiple micro frontends.
- By updating and subscribing to shared state, micro frontends can stay synchronized and maintain consistency across the application.
- API Gateway or Backend Services:
- Micro frontends can communicate with backend services or API gateways to fetch data or trigger actions.
- Backend services can act as intermediaries, handling requests from micro frontends and orchestrating interactions between them.
- This approach allows micro frontends to remain independent while leveraging centralized services for communication.
- Message Bus or Pub/Sub Systems:
- Micro frontends can communicate through a message bus or publish-subscribe (pub/sub) system.
- Each micro frontend can publish messages to specific topics, and other micro frontends can subscribe to these topics to receive relevant messages.
- Message bus or pub/sub systems enable asynchronous communication between micro frontends and support decoupled and scalable architectures.
The mode of communication on the other hand depends on the factors which may include the nature of interactions that are desirable, user performance, and the development being preferred.
What are Micro Frontends?
Among the more widely accepted frameworks at the moment, there is a concept known to be a Micro Frontend. The technique extracts the ideas from microservice architecture in the backend portion and implements them in the front end by breaking down the irrelevant large frontend applications into more manageable self-sufficient components.
