TypeScript support

Related packages


The following software must be installed in order to use Uno and Fuselibs.


  • Android SDK
  • Android NDK
  • Java JDK

These dependencies can be acquired by installing android-build-tools.




Building from source

The following commands will install dependencies, build libraries, and run tests.

npm install
npm run build
npm test

You can run the local uno directly using node_modules/.bin/uno. This is useful when you want to build apps using your local Fuselibs development environment.

Express building

When working with the source code and building often, it can be beneficial to build in express mode.

npm run build -- -e

Express mode will only rebuild the package(s) that have actually changed, skipping rebuilding all dependent packages.

Manual testing

You can run the manual testing app on your desired platform using one of the following commands:

npm run android
npm run android-emu
npm run dotnet
npm run ios
npm run ios-sim
npm run native
