Resolve error :"Unable to resolve module `crypto` in \\azure-mobile-apps-client\\node_modules\\node-uuid\\uuid.js''
I met issue "Unable to resolve module `crypto` in \\azure-mobile-apps-client\\node_modules\\node-uuid\\uuid.js'" when I developed an App using React Native and Azure Mobile App Service. The Azure Mobile App Service uses the crypto module in "uuid.js" such as "require('crypto').randomBytes", because crypto is a core Node JS module, and the React Native packager can’t package it along with app’s Javascript bundle, so it throws a runtime error: Unable to resolve module 'crypto'. I did a research on google.com, and fount out this article " Using Core Node JS Modules in React Native Apps ". Based on this article, I came out a solution to resolve this problem as below. npm install -g browserify Create a file crypto-in.js that imports the crypto module and simply exports it: var crypto=require("crypto"); module.exports=crypto; Create a standalone Javascript bundle crypto.js using browserify in NPM
