读取 npm 包的文件

Question

I have created a npm package named test_package_cat, which is supposed to read a json file (info.json) at the beginning. Thus, index.js (main entry) and info.json are at the same level.

When I run the index.js locally, I can read the file.

either:

fs.readFileSync('info.json') 

or

fs.readFileSync(path.resolve(__dirname, 'info.json')

works fine.

However, when I have another program, a React page,that uses the package, it fails to read the json file.

 cat = require('test_package_cat')
 cat.meow()

When I run index.js locally, if I console.log(__dirname), it gives me C://......../myProject. However, when running the React app, console.log(__dirname) just prints "/" and when I try to print directories/files, it shows nothing.

How can I make the my npm package to read info.json file?

Edit : After more searching, I managed to get it working by doing:

let info = require('./info.json')
console.log(JSON.stringify(info))

but would still like to know how to do it using "readFile" way.

fs is only available in the Node runtime environment. It isn't available in a browser's JavaScript runtime environment. I'm surprised you haven't encountered an error to that effect.
