How do I run a node.js function from an html page without using ajax/using express?

Question

I have been having trouble with ajax, and I just want my html to pass a function when a button is passed, but that function is in a node.js file.

How could I do this without AJAX, and if AJAX is required, could I be linked code?

Answer 1

Create index.js file and attach it to your html (index.html) file.

Then in html file if you are submitting form then pass onClick=functionName() as attribute in <form> tag.

In index.js file, you can add functionName function and that function works as your frontend function.

Use axios or inbuild request to fetch data from that function via endpoint .
