如何从node_modules（自定义模块）读取文件，例如babel读取.babelrc文件

Question

I have a custom package. I tried to use 'fs' as dependancy. but I am getting following error. (but I can see installed module in node_modules folder) Module not found: Error: Can't resolve 'fs'

then I make changes to webpack config as

node: { fs: empty }

then I could able to build. Later I have installed this package in other project and I could n't able to read file. 'error: fs is not installed.'

My goal:

I would like to read a read a file which is under 'src/' folder (like babel reading .babelrc file) from my custom npm package which is under node_module.

Please advice! thankyou!

[Just adding my work around. It could help someone.]

After spending enough time I find my mistake. Built-in node module 'fs' will not available in frond-end when while compile and load in browser.

To get access for fs module, I have to execute script (like node ../abc.js this script will load config file from 'src/' folder) through pre-install/post-install in my custom package. This comes with a problem, any changes to config file need package installation.

I took another approach with webpack. Created a webpack-loader which will be called when my package code is getting parsed and then custom package will get access to 'fs' module to read a file in 'src/' folder. Changes to config will be re-compiled with webpack.
