The app code lives in the app folder. Use yarn to install dependencies.

cd app/
yarn

Create a .env file. See .env.example for environment variables which may be set.

Note for Corona Information Markets

Build directly with react-scripts:

npx react-scripts build

Make sure you do not use yarn build. The build script alters react-scripts to support building with 3Box. If you already used yarn build, remove node_modules and reinstall the dependencies to build optimally for Corona Information Markets.

For normal Omen builds, use yarn build, but for Corona Information Markets, see note above.

The build directory in the app directory will now contain the build to be served.
