Convex, a real-time Backend-as-a-Service provider, simplifies dynamic application development within the React ecosystem, especially when integrated with Kinde Auth using webhooks. This integration allows for seamless synchronization of user data between front-end and back-end systems, addressing challenges such as maintaining up-to-date user information without requiring page refreshes or full authentication processes. By utilizing webhooks, Kinde sends HTTP requests with user signup details to a Convex HTTP Action, which then updates the Convex database with new user records. This process ensures that user data is readily accessible and reactive, allowing for real-time UI updates without repeated queries. A practical example of this integration can be found in the Convex + Kinde Auth starter repository, which demonstrates data synchronization using reactive queries and webhooks. Proper configuration of webhooks is crucial, and testing is advised to ensure secure and efficient data handling, with support available from the Kinde community for any integration challenges.
