MWA - Homework - MongoDB

Given the two models users and courses. And another two sub-schemas of lectures and questions.

Part 1: Design and Implement a Restful API using Express, Mongoose, and TypeScript for the following entities:

• Public POST /auth/signup route to add a new user (use bcrypt and jsonwebtoken to hash the password and generate a JWT).
• Public POST /auth/signin route to verify the user credentials (return JWT).
• Public PUT /auth/password route to change the password (return number of updated documents).
• Create a middleware to verify all private requests. Decrypt the JWT token, assign the token details to req.body['token_data'].

- READ QUERY AND RESPONSE REQUIREMENTS BELOW

Part 2: Implement CRUD operations on the following private entities:

• CRUD courses
  • add a new course (code and title). Fill out the created_by property from the JWT.
  • get paginated courses sorted from newest to oldest, without any lectures details.
  • get one course by ID.
  • update one course (code and title).
  • delete one course by ID.
• CRUD lectures
  • add a new lecture (title and description and file_url).
  • get paginated lectures (use $slice projection operator to paginate over arrays).
  • get one lecture by ID.
  • update one lecture (title and description and file_url).
  • delete one lecture by ID.
• CRUD questions
  • add a new question (question and due_date).
  • get paginated questions (use the $ and $slice projection operators).
  • get one question by ID (you may temporary need to use a child process, ideally, an aggregation pipeline must be used)
  • update one question (title and due_date).
  • delete one question by ID.

Part 3: Geospacial implementation:

• Implement a route to find the nearest 10 users that match a certain set of hobbies. You will need to create and use a 2d index.

- QUERY AND RESPONSE REQUIREMENTS

• Only authenticated users may send requests to the private routes.
• Only the user who created the course should be able to perform Create/Update/Delete operations on courses and lectures and questions. However, anyone can Read the data.
• GET results must always be paginated.
• The standard response signature is interface IResponse<T>{ success: boolean, results: T }. Where <T> represents the returned type as follows:
  • GET all, must return Entity[] (with pagination).
  • GET one, must return Entity. (use child process for getting one question by id)
  • POST returns a string represents the ObjectId of the newly added object.
  • PUT returns a number of how many objects were modifed.
  • DELETE returns a number of how many objects were deleted/modifed.
