My existing project I have : 

Frontend Framework - **PHP Codeigniter** and **PHP Laravel**

Backend Framework - **JAVA Springboot**

I'm trying to change Frontend Framework to **ReactJS**. I want to know what is the most popular backend framework to use with ReactJS and Why? Please explain. Should I change Backend Framework from Springboot to other one such as **ExpressJS**?. How about the performance?.

Thank in advanced.
