Knowledge Tracker (Spring Boot + Postgres)

A portfolio-grade Spring Boot app to save and track learning resources.

Stack

• Spring Boot 3 (Web, Thymeleaf, Data JPA, Security, Validation, Actuator)
• PostgreSQL + Flyway migrations
• Docker + Docker Compose

Quick start

With Docker

# From project root
docker compose up --build

• App: http://localhost:8080
• Postgres: localhost:5432 (db: knowledge / user: postgres / pass: example)
• MailHog (dev SMTP): http://localhost:8025

Local (without Docker)

# Requires Java 17 and Postgres running locally at 5432
./mvnw spring-boot:run

Configuration

• See src/main/resources/application.yml for defaults. Override with env vars:
  • SPRING_DATASOURCE_URL, SPRING_DATASOURCE_USERNAME, SPRING_DATASOURCE_PASSWORD
  • PORT

Next Steps

• Implement entities, repositories, and REST API per design doc
• Add JWT auth (access + refresh tokens)
• Build resource CRUD UI (Thymeleaf) and CSV export
• Add scheduled jobs and dashboard metrics
