Findal EX: REST + Graphql

Chapter I

• Create a new express project connected to sequelize
• Create a new model and migration for User which contains the fields: firstName, email, password
• Create a REST API for getting all the users, register a user, login a user
• The login and register should provide a JWT token as well
• The password in the users table should be hashed using the library bcrypt
• Create the same API with GraphQL

Chapter II

• Create a todo table and model
• create a many to many associations between the user and the todo, every user can create many todos
• serve that data using graphql, make sure you are able for each user to get all his messages and for each message to get his user

Chapter III

• reading the todo list should be restricted to registered users
• only if you pass the JWT token in the headers: Authorization will you be able to read it.
• using passport add the JWT authentication to the todo rest api
• Can you do the same with the GraphQL todo api?

Chapter VI

• Add unit tests for all the apis
