Using the Unleash Feature server in a browser for React projects: A step-by-step guide

I'm currently working on implementing the unleash feature toggle in my React Project. Everything is running smoothly with the backend server (thanks to the Java SDK), but I've hit a roadblock when it comes to making unleash requests from the browser (using React for the frontend). While going through their GitHub repository, I discovered the concept of an unleash proxy which allows us to access toggles from the browser. However, when attempting to connect through the proxy from the browser, I encountered a CORS issue. Can anyone provide guidance on how to set up CORS headers for the unleash server that is running in a Docker container?

Answer №1

If you want to integrate Unleash in frontend and native applications, it's best practice to utilize the Unleash Proxy in conjunction with a proxy SDK

By using the proxy, you can prevent exposing sensitive toggle configurations to end users while also achieving high scalability.
