Checklist

  • 1. Create a backend using ExpressJS.
  • 2. Create a PWA using React that that accepts text input and sends it to the backend. Bonus : UI changes on interaction
  • 3. The backend should have the following 3 functionalities -
    • a. log the number of times a connection is made by the frontend and insert it into a Mongoose Model
    • b. receive the text that was inserted from the frontend and insert it in another Model
    • c. calls the Django api using the most recent 2 strings and returns the ngrams to the frontend
  • 4. Create a Django server that has an API that returns the ngrams comparison using NLTK.
  • [] 5. Create a new repo on GitHub
    • a. which has all the commits
    • [] b. independent branches for the 3 pipelines that are merged for submission. Make sure that there are merge conflicts that you can resolve and show you skills.
  • 6. Bonus : Containerise each of the components (Node frontend, Node backend, Django Backend) on independent docker containers
