title: Twilio React Native - Unable to resolve module crypto
body: <p>I'm working on implementing the <code>twilio</code> package into my react-native project and when I require it in my file the project wont load and I'm seeing the following error:</p>
  
  <p><code>Unable to resolve module crypto from /Users/[myname]/Documents/Projects/React-Native/[app-name]/node_modules/twilio/lib/webhooks.js: Unable to find this module in its module map or any of the node_modules directories under /Users/node_modules/crypto and its parent directories</code></p>
  
  <p>I've tried installing the <code>crypto</code> package directly and that doesn't seem to work either.</p>
  
  <p>Has anyone experienced this issue, and has a way to resolve it?</p>
