Using npm modules in React Native projects

Well, it’s quite opposite. React Native actually runs within io.js runtime so most pure javascript modules for node will work. On the other hand most front-end modules written for React.js will not work for React-Native.

React Native does not use HTML DOM nor CSS as we know it from the web. It replaces the CSS/HTML DOM with the native view representation. So any front-end packages that are supposed to use HTML and be displayed in browser will not work.

On the other hand, any modules that are pure javascript and run within node.js/io.js are perfectly OK to be run in react-native.

For example, I am quite sure that Facebook uses their ‘relay’ data access library in their react-native apps (it’s a javascript library that efficiently communicates over Facebook’s Open Graph API and allows to access Facebook user’s data).

The way to do it is the same as in other node.js/io.js apps. Simply run

npm install module –save

and you are done (package.json will be automatically update with the dependency for the module). Then you can use the package as usual.
