React Native: Unable to resolve module fs

Question

Unable to resolve module fs from /...mypath 

I got this error when trying to import a node module into my react-native app.

The module used 'fs' in this way:

var fs = require('fs'); var list = JSON.parse(fs.readFileSync(__dirname + '/list.json', 'utf8'));

I ended up using 'rn-nodeify' to include fs into React Native. You can use most of the node core modules this method. Install it with npm:

npm install rn-nodeify 

Then in package.json file, add the following line in "scripts" to specify which modules you want to include in your RN project. For example, I used fs, crypto and https, and the line goes

"postinstall": "node_modules/.bin/rn-nodeify --install crypto,fs,https --hack"
