How to edit pdf file using js?

Question

JavaScript

I will describe the task:
There is a certain table, this table must be filled with data and given to the user in pdf format. The application is written using Electron.
I see here 2 options for solving the issue:
1. Make up a table in html and insert data there during the request and convert it all to pdf;
2. Take a pdf template, where instead of the necessary data there will be variables, for example {limit}, somehow we substitute the necessary data instead of the variable and give it to the user.
Here, according to the second option, the question is, is it possible to implement this at all, if so, how?
