Upgrading to new versions of React Native will give you access to more APIs, views, developer tools and other goodies. Because React Native projects are essentially made up of an Android project, an iOS project and a JavaScript project, all combined under an npm package, upgrading can be rather tricky. But we try to make it easy for you. Here's what you need to do to upgrade from an older version of React Native:
1. Upgrade the react-native dependency
Note the latest version of the react-native npm package from here:
Open your package.json file and update the version of react-native under dependencies to the
latest version. Now, in a terminal run:
$ npm install
2. Upgrade your project templates
NOTE: This feature is not yet available in the stable release of React Native. Stay tuned.
The new npm package will likely contain updates to the files that are normally generated when you
run react-native init, like the iOS and the Android sub-projects. To get these latest changes,
run this in a terminal:
$ react-native upgrade
This will check your files against the latest template and perform the following:
- If there is a new file in the template, it is simply created.
- If a file in the template is identical to your file, it is skipped.
- If a file is different in your project than the template, you will be prompted; you have options
to view a diff between your file and the template file, keep your file or overwrite it with the
template version. If you are unsure, press
