Send sensor data from arduino nano to firebase using esp8266-01

I am new to IoT world and i am having trouble programming my esp8266-01. Day and night, I tried to search and search for the right connection and code but nothing seems to work. Is it possible to connect to firebase using esp8266-01? If so, please do help me. Thank you!

I put “firebase esp8266” into a well-known search engine.
Sadly, the first hit was an Instructable, but I’m sure there must be more useful stuff in the other results

true, its always nodeMCU also. Do you have any idea if its possible?
