The goal of this serie of posts is to achieve quickly a simple museum Audioguide web app based on a React isomorphic boilerplate with a Drupal 8 backend that uses the latest standards. The web app will be fully decoupled by being hosted on another domain than the Drupal one. As a real world case, we want it to be fully multilingual. This is the first post of a serie of 3. This first one focuses on having a Drupal and React setup that meets our requirements. The second one will define a MVP that will just fetch the audioguides list and a detail view (GET operation), the last one will then add extra features like getting user feedback (POST operation).
