Recently, I was creating a program called "EntomoConnect". This platform allowed users to make observations for others to see and eventually discuss. However, I found myself stuck for days due to a Proxy Error between my frontend and backend. While I was successfully making "GET" and "POST" requests through Postman, I struggled to achieve the same through the frontend. Despite both sides seemingly configured correctly, I constantly found myself checking and re-checking, ensuring both were running on communicating ports. My breakthrough came when I stumbled upon setupProxy.js.
What even is setupProxy.js?
setupProxy.js is a configuration file utilized during environmental setup, especially with tools like Create React App. It offers a structured method to route requests from your frontend to your backend services, effectively managing proxy details.
Why use setupProxy.js?
In my journey, I was able to replicate the production environment by directing frontend requests to my backend, even when they operated on different local ports.
This tool didn't just bridge that gap. It also streamlined my CORS policies, ensuring seamless communication between frontend and backend, which significantly enhanced the development process.
Within setupProxy.js, I was able to adjust routes, alter headers, and even mock responses. This flexibility simplified and aided in my testing phase.
While the proxy error initially appeared as a daunting barrier, setupProxy.js not only helped me navigate around it but also enriched my overall development experience. Such tools sparked my enthusiasm, making me eager about future projects and the innovative answers I might encounter next.
