Not every app uses all the native capabilities, and including the code to support all those features would impact the binary size... But we still want to support adding these features whenever you need them.
With that in mind we exposed many of these features as independent static libraries.
For most of the libs it will be as quick as dragging two files, sometimes a third step will be necessary, but no more than that.
All the libraries we ship with React Native live in the
Other libraries also rely on some native code, in that case you'll have to add these files to your app, otherwise the app will throw an error as soon as you try to use the library.
Here are the few steps to link your libraries that contain native code
Install a library with native dependencies:
npm install <library-with-native-dependencies> --save
--save-dev flag is very important for this step. React Native will link your libs based on
devDependencies in your
That's it! Next time you build your app the native code will be linked thanks to the autolinking mechanism.
If the library has native code, there must be an
.xcodeproj file inside its folder. Drag this file to your project on Xcode (usually under the
Libraries group on Xcode);
Click on your main project file (the one that represents the
Build Phases and drag the static library from the
Products folder inside the Library you are importing to
Link Binary With Libraries
Not every library will need this step, what you need to consider is:
Do I need to know the contents of the library at compile time?
If you do need to call it from native, then we need to know the library's headers. To achieve that you have to go to your project's file, select
Build Settings and search for
Header Search Paths. There you should include the path to your library. (This documentation used to recommend using
recursive, but this is no longer recommended, as it can cause subtle build failures, especially with CocoaPods.)
