Must be the same port that the one defined in REACT_APP_API_URL at the start script of the frontend - File: package.json). For example: PORT=4000 MONGODB_URI=mongodb://127.0.0.1:27017 SECRET='my_secret'
• Run the fabric network from the root directory with the command ./ehrNetwork.sh up
• In /web-app/backend/ execute npm run dev to run the node.js server.
• In /web-app execute npm start to run the reactJS application.
• Run GET /admin/ in the backend to enroll admin
