Authentication

Build a user signup and login application using a layered architecture. It must contain a User model that includes an email and passwordHash.

Requirements

You must check for authentication using express middleware. Your /login route should also store a cookie with the logged in user's id.

Use the red, green, refactor process. Work vertically, fully completing each route before moving to the next.

Each route requires the following:

• Test(s) (including for each subcondition)
• express route
• Model method
• Related SQL schema

Rubric

• POST route to /signup that responds with a newly created User's id (3 points)
  • If the email already exists, return 400 (1 point)
• POST route to /login that responds with the existing User's id (3 points)
  • If credentials are incorrect, return 401 (1 point)
• GET route to /me that responds with the currently logged in User. (2 points)
  • DO NOT RETURN THE USER'S passwordHash! If you do... MINUS 5 POINTS!!!! (Seriously)
