Architectural Patterns of Micro Frontends
Several architectural patterns can be employed to implement Micro Frontends:
1. Single-SPA (Single Page Application):
In this pattern, the entire application is a single-page application (SPA) composed of multiple micro frontends.
- Each micro frontend represents a self-contained section of the application, and the routing logic dynamically loads and integrates these micro frontends into the SPA based on the requested URL.
- Single-SPA provides a unified approach to managing multiple micro frontends within a single application, allowing for seamless navigation and user experience.
2. Composition at the Edge:
In this pattern, composition of micro frontends occurs at the edge of the network (e.g., CDN or reverse proxy), rather than in the client’s browser.
- Edge servers dynamically assemble the user interface by fetching and combining micro frontends from various sources based on the requested URL or user context.
- Composition at the edge improves performance by reducing client-side processing and latency, as well as enhancing security by centralizing composition logic.
3. Client-Side Composition:
In this pattern, composition of micro frontends occurs on the client-side, typically in the browser.
- The client-side router or orchestrator dynamically fetches and integrates micro frontends into the user interface based on the requested URL or user interactions.
- Client-side composition offers flexibility and responsiveness, allowing for dynamic updates and interactions without requiring server-side processing.
4. Server-Side Includes (SSI):
In this pattern, the server dynamically includes or includes micro frontends into the server-rendered HTML response based on the requested URL or user context.
- Server-side includes (SSI) allow for efficient server-side composition of micro frontends, reducing client-side processing and improving performance.
- SSI can be implemented using server-side templating languages or edge computing platforms to assemble the user interface on the server before sending it to the client.
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.
