Fingerprint sensor with nodemcu

Hello everyone, i have designed a program where I have used and modified Adafruit Fingerprint Sensor Module and used it with Fingerprint Sensor R307,arduino UNO and Arduino IDE.
Now my assigned task is to remove the UNO board and use NodeMCU instead of it.
How can I flash the same program in NodeMCU??
What will be the connections??
Can anyone please help me out??

What kind of board do you have and what have you used so far to program it?
