After developing an npm package, I included some modules in the node_modules directory to make them accessible as "modules". For instance, I have a module called my-module.js in node_modules which I require in my code using require('my-module'). Upon running "npm publish" and then installing my module in another project by running "npm i", I noticed that my modules are missing from the node_modules folder. To troubleshoot this issue, I attempted adding the following lines to .gitignore and .npmignore:
node_modules/*
!node_modules/my-module.js
Despite trying these steps, the problem persists. What am I doing incorrectly?
