There are several things in the Dummy Bank application which can be improved. Your goal is to complete the following checklist of tasks that need to be implemented/fixed/refactored.

Tasks:

1. Eliminate deprecation warnings when running the server
2. Implement deposit functionality
   • In the profile page, add a form wherein the user can deposit an amount to his/her account.
3. Implement withdraw functionality
   • In the profile page, add a form wherein the user can withdraw an amount to his/her account.
4. Create Account instance on sign up
   • Currently, when signing up only a User instance is created. Modify the signup workflow to also create an Account instance for that user after the user signs up.
   • Make sure to do them within a database transaction to make sure that all changes are discarded if either operation fails.
5. Implement retrieveSignedInUser middleware
   • This middleware should add the currently signed in user's User instance to req.user.
   • Also use the middleware in parts of the existing code wherein it would add improvements in terms of removing repetitive code, etc.
6. Move Twitter sign in routes to routes/twitter.js
   • Make sure sign in with Twitter still works.
7. Move auth-routes.js to routes/auth.js
   • Make sure authentication still works.
8. Add name field to the User model.
   • This field will contain the user's full name retrieved from Twitter sign in.
9. Display user's name in profile page
   • If the name is not available, display email instead.
10. Optimize the database queries in the /transfer route
    • There are four queries that could be optimized:
      • Getting the sender User instance
      • Getting the receiver User instance
      • Getting the sender Account instance using the id from the User instance
      • Getting the receiver Account instance using the id from the User instance
    • Reduce them to a fewer number of queries.
    • Hint: You can use SQL JOINs or sub-queries.
    • You may run raw SQL queries if you want to.

Bonus Tasks:

• Make the dummy bank pages look good.
• Implement another social authentication besides Twitter
  • You can do signin with Google, Facebook, Github, etc.

Instructions:

• This lab exercise will be done by group.
  • You may choose your own groupmates.
  • Each group must have a maximum of three members.
  • Update (members: ) at the top of this file with a comma-separated list of your group's Gitlab usernames.
• Fork this repository into one group member's personal account.
• Indicate which bonus tasks did you implement.
  • Change [ ] in the Bonus Tasks list to [x]
