• NodeJS v8+

• Install dependencies with yarn or npm install
• Run API server with yarn server
• Run client app with yarn start

Note that yarn server and yarn start are only splitted in development mode -- front-end application is delivered through the API server after application build.

Tests can be executed with yarn test or npm run test:

$ yarn test
(...)
 PASS  src/App.test.js
 PASS  src/containers/PhotoStreamContainer/index.test.js
 PASS  src/components/PhotoGrid/index.test.js
