Is there a way to link my node js code to my website?

My code is a web scrapper(currently runs with a .txt file for inputs) and I want to link it to my website yet I have no clue how to go about it.
Essentially, I want to create a monthly subscription and for customers to enter requests and my code to fulfil them.
how would I go about this? Its almost like I need a messaging service to connect both together.
Thank you
