I have just created a new project using react-native init Project --template typescript (which is the official way of starting a new project with TypeScript now), configured and installed everything, but the app fails when creating a connection. Here is a screenshot of what shows up:

Config files:

babel.config.js

module.exports = {
  presets: ['module:metro-react-native-babel-preset'],
  plugins: [
    'babel-plugin-transform-typescript-metadata',
    ['@babel/plugin-proposal-decorators', { legacy: true }],
    // ['@babel/plugin-proposal-class-properties', { loose: true }]
  ]
};

(class-properties is commented due to another issue with Babel 7 and Flow)

App.tsx#connect

  async connect() {
    await createConnection({
      type: 'react-native',
      database: 'gestor',
      location: 'default',
      logging: ['error', 'query', 'schema'],
      synchronize: true,
      entities: Object.values(models) // this evaluates to an array of entity classes
    });
    Alert.alert('hello!');
    this.setState({ loading: false });
  }

Nevermind. For anyone in the future with the same error, using react-native link or react-native install does not work with react-native-sqlite-storage. You have to add the dependencies manually.
