Project Proof of Concept

Express server setup complete
MongoDB Connection established

• Database populated with user, room and building data using POSTMAN

• 3 model-schema created:
  

  • user-model, room-model and building-model

• DAOs:

  • userDAO: complete.
  • roomDAO: in-progress. Implemented text search and aggregate (lookup and sort)
  • buildingDAO: in-progress

• Routes:

  • user-Model: POST/ route, GET/ route, PUT/ route, DELETE/ route setup complete.
  • room-Model: POST/ route and POST with aggregate/lookup complete. DELETE route complete.
  • building-Model: POST/ route, GET/ route, DELETE-route complete

• Authentication and authorization routes complete.

• Self-Evaluation
  

What I learnt:

Learned about the structure of Express back-end development and how to build an application and implement CRUD routes. I learned how to use MongoDB, write basic routes as well as advanced MongoDB operations. How to integrate middleware and use unit-tests. Definitely need more practice with tests.For the final project the test coverage is a little over 80%.

What worked:

• Taking up a simple case study scenario helped.This allowed more time to work on writing code and finding best ways to create CRUD routes rather than get caught up on the end goal.
• Using different complexities of modelSchema was helpful. This helped choose indexes and allowed for better testing,
• Using POSTMAN instead of building a simple frontend UI was helpful as it put me in the shoes of a purely backend developer thus requiring me to test the routes using an API testing environment.
• Using authentication and authorization helped understand how a real app would function.
• This also led to a deeper understanding of what fields can be changed through a user input vs manipulated through the database on the backend.

What did not work:

• Adding tests at the end was tiresome and frustrating.
• Struggled adding authentication for the room/ route tests
• Struggled adding checks for finding rooms, buildings in the database for tests.
• Need more practice using .aggregate()

What would I do differently?

• Setup routes and tests simultaneously!!
• Setup a new model that inputs time and finds time duration.
• If there was more time, I would have liked to write more granular tests.
• Build a simple front-end UI app.

Overall a great learning experience!
