title: How to read Spring Boot application.properties in ReactJs app?
body: <p>We have 2 configuration files: one is in our Spring Boot application (application.properties) and another in our ReactJs app (we use .env in create-react-app). It was decided to use Spring Boot application.properties also in ReactJs app. Can anyone please guide me how can I achieve this?
  I have read about "properties-reader" and tried to use it, but I don't have webpack.config.js file in our ReactJs app.</p>
