Most project and tutorial uses nodeMCU as the module for sending data to firebase.
I really need help. Thank you in advance.

The ESP-01 is not as easy to use as a Bluetooth module. The peak current requirements are much higher. And this can lead to unstable operation.
You will write a program and you will never know if the unstable operation is caused by code issues or by poor power. It is highly recommended to develop with a Nodemcu or Wemos type board. Get your code working on those, and then if you have a good reason to want a bare module then give it a try.
Not seeing the test.css file but basic code works.[…]
