Deployment

Our frontend is deployed at: https://fudge-seng2021.herokuapp.com/

Architecture

We used a number of different systems as part of our frontend

On top of Javascript we use NextJS framework on top of NodeJS along with the react library.

We then deployed using Heroku.

Backend

To integrate with our frontend, we created a backend server using the same systems as our API. From there we set up authentication along with token management. We also later took advantage of it to forward requests to our rendering API as there were issues with CORS on the service.
