Fix CORS Policy issue when calling api to another domain service. reactjs (English version)
Why Stack Overflow recommends it
Stack Overflow users link it when a React frontend hits a CORS block and they want a step-by-step proxy setup shown on screen rather than the library's readme.
Recommended by 3 people across 3 different months, 2021 to 2023.
What it is
A short tutorial by Code with Jenny on fixing browser CORS errors in a React app that calls an API on another domain. It walks through setting up the http-proxy-middleware library as a development proxy, and links the MDN CORS documentation.

I did use 2 solutions to dealing with it: Using http-proxy-middleware . However, please do following below steps on video, instead of read me of library, [this video] . (I did mention the weakness if you use this solution also) Use Firebase functions to create middleware, not too complicated. I will update detail then here also. Please let me know if you have any question.
