Task Management Application

A simple Task Management API built with Node.js, Express, Sequelize, and MySQL. Supports user registration, login, and simple CRUD operations for tasks.

It was completed as a technical assessment for an application to a local telecommunications company in the Philippines, with a one-day time constraint.

The goal of the exercise was to demonstrate my understanding of core frontend concepts, application state management, and interaction with data flows within a limited timeframe.

Run with Docker

docker-compose up --build

After running docker-compose up --build, you can access the backend at http://localhost:3000 and frontend at http://localhost:8080.

API Endpoints

Method	Endpoint	Description
POST	/api/user	Register new user
POST	/api/login	Login and get JWT
POST	/api/task	Create task
GET	/api/task/:user_id	Get user’s tasks
PUT	/api/task/:task_id	Update task
DELETE	/api/task/:task_id	Delete task

Tech Stack: Node.js + Express MySQL + Sequelize JWT + bcrypt Docker + Docker Compose

Notes

• Ensure the MySQL container is running and healthy before starting the app.
• Environment variables (e.g., DB credentials) are configured in docker-compose.yml.
• All responses are in JSON format.
• Error codes and messages are currently logged to the console (for testing purposes only).
• JWT tokens expire after 12 hours and use "TEST" as the signing key.
• The MySQL root user is used; stored procedures and indexes were not implemented but should be considered in production.
• TypeScript types are not defined, and many frontend styles are repeated. No design toolkit was used; styling is done with styled-components.
• useMemo and useCallback could be applied in the frontend to avoid unnecessary re-renders when context data hasn’t changed.
• The Docker image artifact is successfully created in GitHub Actions. However, docker load -i task-management-app.tar sometimes freezes. Root cause has not been determined yet.
