Answer 1

Requirement

// Meh
import config from '../../../../../../../config';

// Awesome!
import config from '@cuteapp/config';

How To

1. Add this babel plugin package

yarn add --dev babel-plugin-module-resolver

2. My babel.config.js

module.exports = {
  presets: ['module:metro-react-native-babel-preset'],
  plugins: [
    [
      require.resolve('babel-plugin-module-resolver'),
      {
        cwd: 'babelrc',
        extensions: ['.ts', '.tsx', '.js', '.ios.js', '.android.js'],
        alias: {
          '@cuteapp': './app'
        }
      }
    ],
    'jest-hoist'
  ]
};

3. My tsconfig.json

{
  "compilerOptions": {
    "allowJs": true,
    "allowSyntheticDefaultImports": true,
    "esModuleInterop": true,
    "isolatedModules": true,
    "jsx": "react",
    "lib": ["es2015", "es2015.promise", "es2016.array.include", "dom"],
    "strict": true,
    "moduleResolution": "node",
    "baseUrl": "./",
    "paths": {
      "@cuteapp/*": ["app/*/index", "app/*"]
    },
    "noEmit": true,
    "resolveJsonModule": true,
    "target": "esnext",
    "types": ["jest"]
  },
  "exclude": ["node_modules", "babel.config.js", "metro.config.js"]
}

4. That's it.
