Comprehensive Node.js solutions for task orchestration, real-time collaboration, and operational log analysis. The workspace hosts three independent services that share common engineering principles: consistent validation, observable error handling, and automation-friendly tooling.

• task-management-api/ – RESTful service that secures, schedules, and monitors tasks for distributed teams.
• websocket-chat/ – Event-driven WebSocket gateway enabling instant messaging and presence updates.
• log-parser-cli/ – Command-line utility for parsing application logs and extracting actionable metrics.

• Purpose: Delivers authenticated CRUD endpoints for tasks, providing filtering, prioritisation, and deadline management.
• Stack: Node.js 18+, Express, Mongoose, JSON Web Tokens, express-validator, Jest.
• Key Capabilities:
  • Token-based authentication with role-ready structure.
  • Centralised validation middleware and consistent problem-detail responses.
  • MongoDB persistence with lifecycle hooks for password hashing.
• Quick Start:
  1. cd task-management-api
  2. npm install
  3. Copy .env.example to .env and set MONGO_URI, JWT_SECRET.
  4. npm run dev
• Testing: npm test

• Purpose: Provides bi-directional real-time messaging with room-based isolation.
• Stack: Node.js, ws (WebSocket library), Redis (optional) for pub/sub scaling.
• Key Capabilities:
  • Broadcast and direct messaging channels.
  • Connection lifecycle hooks for join/leave notifications.
  • Extensible event schema for future moderation features.
• Quick Start:
  1. cd websocket-chat
  2. npm install
  3. npm start
• Integration Tip: Use the provided sample HTML client or integrate via native WebSocket clients with JSON payloads.

• Purpose: Extracts insights from structured and semi-structured logs to support operational reporting.
• Stack: Node.js, commander, chalk.
• Key Capabilities:
  • Pluggable parsers for JSON, CSV, and delimited formats.
  • Filters by severity, timestamp, and custom predicates.
  • Export to CSV or JSON for downstream analytics.
• Quick Start:
  1. cd log-parser-cli
  2. npm install
  3. node ./src/index.js --help
• Example: node ./src/index.js parse --input ./logs/app.log --format json --level error

• Code Quality: ESLint and Prettier configurations ensure consistent formatting and linting across projects.
• Testing: Unit and integration suites run via npm test; new features require coverage extensions.
• Security: Environment variables hold secrets; avoid committing .env files. JWT secrets must be strong and rotated periodically.
• Observability: Each service includes structured logging helpers ready for integration with centralized log platforms.
