Emotional Tracker - Technical Test

This project is a technical test for evaluating candidates' coding skills. It's a mental wellbeing tracking application that allows users to record their emotions between therapy sessions.

Project Structure

• /frontend - Next.js application with Styled Components
• /backend - Express.js server with MongoDB database
• Docker configuration for easy setup

Getting Started

Prerequisites

• Docker and Docker Compose

Installation

1. Clone the repository
2. Run Docker Compose:

docker compose up

This will start:

• Frontend at http://localhost:3000
• Backend at http://localhost:5050
• MongoDB at localhost:27017

Test Data (Seeding)

The application includes a system to generate test data, making it easier to test the functionalities.

Included Data:

• Users:

  • Email: test@example.com / Password: password123 (role: user)
  • Email: admin@example.com / Password: admin123 (role: admin)
  • Email: maria@example.com / Password: maria123 (role: user with therapist)

• Emotions: Each user has 15 random emotion records from the last 30 days.

Options to run seeds:

1. Manual (from command line):

   cd backend
   npm run seed

2. Automatic (during Docker startup):

   • Edit the docker-compose.yml file
   • Change the SEED_DATABASE environment variable to true:

   backend:
     # ...
     environment:
       - MONGO_URI=mongodb://mongodb:27017/emotionaltracker
       - JWT_SECRET=mysecretkey123
       - SEED_DATABASE=true  # Change to true to generate test data

   • Restart containers: docker compose down && docker compose up
