Task Tracker

About

A microservices-based task management system built with Go, using database/sql for low-level database access and goose for migrations.

Features

• User registration with bcrypt password hashing (REST API: POST /register).
• (In progress) User login with JWT, task/board CRUD, WebSockets.
• Rate limiting to prevent brute-force attacks.
• Docker support for easy setup.

Architecture

• Multi-module: auth-service, tasks-service, and shared in a single repository (github.com/chepyr/go-task-tracker).
• Services:
  • auth-service: User registration/login with JWT, rate limiting, bcrypt.
  • tasks-service: (WIP) Boards/tasks CRUD, WebSocket updates.
• Database: PostgreSQL with goose migrations.
• Concurrency: Thread-safe operations using mutexes.
• Testing: Unit and integration tests with go test -race, ~75% coverage --- TODO

Usage

Start the services using Docker Compose:

docker compose up --build -d

Run database migrations using goose:

# auth-service
goose -dir auth-service/migrations postgres \
"host=localhost user=postgres password=pass dbname=auth_db port=5432 sslmode=disable" up

# tasks-service
goose -dir migrations postgres \
"host=localhost user=postgres password=pass dbname=tasks_db port=5433 sslmode=disable" up

Test the services using curl:

# User registration
curl -X POST http://localhost:8081/register \
  -H "Content-Type: application/json" \
  -d '{"email":"anya@example.com","password":"secret"}'

# Login and save token
TOKEN=$(curl -s -X POST http://localhost:8081/login \
  -H "Content-Type: application/json" \
  -d '{"email":"anya@example.com","password":"secret"}' | jq -r '.token')

# Create a board
curl -v -X POST http://localhost:8082/boards \
  -H "Authorization: Bearer $TOKEN" \
  -H "Content-Type: application/json" \
  -d '{"title":"My Board","description":"For tasks"}'

Tests

Run tests with

cd auth-service && go test ./... -race -cover
cd tasks-service && go test ./... -race -cover
