🏆 48 Hour Backend Technical Challenge

The backend solution is an API for managing employees with just 3 controllers, using MongoDB for persistence, request validation with express-validator, and try-catch blocks to make the application understandable and easy to debug.

I personally used a Mongo Docker image and Render for deployment!

Github Workflow

• db-image: branch is responsible for creating the mongodb container which serves as the database.
• feature: branch will contain all project requirements divided into sub branches and labeled with enhancements.
• release: branch is merged into the main branch when the work is tested and completed.

More documentation is included in the issues tab.

Playing with the solution

• To build the application (generate the javascript dist) :

npm run build

• To run the application in the development mode :

npm run dev

• To run the mongo docker container (MongoDB database in a container created with few commands and isolated form the OS):

// navigate to docker compose
> cd ./db 

// run docker compose file in detached mode
> sudo docker compose up -d

// open the mongo shell to interacte with the database
> docker exec -it personal-mongo-database mongosh

YOURE INSIDE THE CONTAINER NOW YOU CAN LIST DATABASES, USE ONE, DO ANY CRUD OPERATIONS...

    # list all databases
    > show dbs

    # use a specific database
    > use db_name

    # see all the collections of the database selected
    > show collections

    # list all documents in a collection
    > db.db_name.find()

Demos of the backend application in action XD

the test is performed using Thunder Client

I recorded the tests before adding the reqeust validation branch

• POST /employees: Add a new employee: demo for adding new employee

• PUT /employees/:id: Update an existing employee's details: demo for updating an employee

• DELETE /employees/:id: Delete an employee by ID: demo for deleting an employee

I recommand to see the issues tag in the process of understandimg the solution (ordered) implementations:

Also reading the mentionned pull request in every issue is a good win !
