Optimizing API Integration in a Large-Scale React Application Using OpenAPI Generator
Tools-in-Action (INTERMEDIATE level)

At CERN’s Business Computing Group, we're developing a large-scale React UI for one of CERN’s biggest business applications.

Integrating OpenAPI Generator into React brings clear benefits, but the process isn’t always straightforward.

With no official guidelines or common patterns, developers often create their own strategies to integrate OpenApi Generator into React apps, which can lead to common pitfalls like excessive boilerplate and inefficient memory usage.

To address this, we built an open source React library that wraps and optimizes OpenAPI-generated clients using a custom hook, making a better use of memory and streamlining API calls.

In this talk, we’ll share the challenges we faced, the mistakes we learned from, and how our open source solution helps making OpenAPI Generator work better in React applications, improving performance, maintainability, and the developer experience.
