Top 3 Aggregation Patterns to Simplify Communication between Frontend and Backend

These are the top 3 aggregation patterns which apart from simplifying frontend backend communication can also improve performance, scalability, and maintainability of your system.

Hello friends, if you have worked in frontend and backend development then you may know that making multiple API requests to render a single page creates unnecessary complexity and performance bottlenecks.

Each additional request increases network latency, adds development overhead, and degrades the user experience.

Research shows that even small delays in page load times can significantly impact user engagement and conversion rates — with a 100ms delay reducing conversion by 7%.

Implementing efficient data fetching patterns isn’t just about following best practices; it’s essential for building responsive, maintainable applications that keep both developers and end-users satisfied.

Aggregation patterns provide proven solutions to simplify communication between the frontend and backend, making your applications faster, more scalable, and easier to maintain.

In the past, I have talked about things like API Gateway vs Load Balancer and Horizontal vs Vertical Scaling, and Forward proxy vs reverse proxy and in this post, I am going we’ll dive into three proven aggregation patterns that your users (and your fellow developers) will absolutely love

1. Central Aggregating Gateway

The Central Aggregating Gateway pattern acts as middleware, consolidating multiple backend API calls into a single response. Here’s how it works:
