Navigate into Client folder in your CMD and type 'yarn install' and then 'npm run dev' to start the client side of the application Then open another CMD and navigate into the Server folder and type 'npm start' to start the server
You would need an .env file in the server to add Sendgrid Key, host email, JWT key and Database credentials which would be like as below:
DATABASE = xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
JWT_SECRET=xxxxxxxxxxxxxxxxxxxxxxxxx
SENDGRID_KEY=SG.xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
EMAIL_FROM=xxxxxxxxx@gmail.com
