Hello everyone! I am creating a Progressive Web App(PWA) and wanted to link it to firebase : As of now, I have successfully updated my data by manually making changes in firebase database and displaying it out in real time on my PWA. 
But now I wish to write/ insert data into realtime firebase database and simultaneously display the changes. 

My question is, how do we push data from a React WebApp to the real-time firebase database. I wasn't able to find any docs or videos on this matter.
Kindly Help.
