UberWhether you're a senior architect who knows what good architecture looks like, or a growing developer who wants to learn enterprise patterns — you don't need another toy project. You need production-ready patterns that scale to millions of users and handle real-world complexity.
Skip the infrastructure work. Get DDD, CQRS, event sourcing, and enterprise patterns that would take months to implement correctly. Learn by doing with production-ready code.
Built for millions of video uploads. Background processing, job queues, observability, and monitoring included out of the box. Study how real systems scale.
Authentication, authorization, validation, error handling, logging, and testing patterns that work in real production environments. Learn from battle-tested code.
Handle multiple formats, sizes, and concurrent uploads with validation
Non-blocking video transcoding with Redis queues and progress tracking
Attach audio tracks to videos with format conversion
Automated resource management and temporary file cleanup
Admin operations, user permissions, and secure API endpoints
OpenTelemetry integration, custom spans, and system health checks
Unit, integration, and E2E tests with high coverage
Every component is explicit, composable, and replaceable
Every feature is designed with scalability, maintainability, and production-readiness in mind. No shortcuts, just solid engineering principles.
The project is structured into bounded contexts with clear separation of concerns. Each feature encapsulates its domain logic using aggregates, value objects, and repositories.
Commands and Queries are fully decoupled using DomusJS buses. Commands mutate the system and emit domain events, while Queries handle data retrieval via separate read models.
Implements a pluggable strategy system for authentication. A PasswordAuthStrategy is included, but you can register other providers like GitHub, Google or OTP-based login.
API routes are protected with JWT-based middleware. Upon login, users receive a token that must be included in subsequent requests. Tokens are signed and expire after 1 hour.
Out-of-the-box integration with OpenTelemetry for full tracing of commands, queries, and background jobs. Custom spans and context propagation included.
Heavy video processing tasks are delegated to background jobs. The jobs module handles retries and failures.
Includes an example of a scheduled cron task to clean up expired temporary files from the storage system. Easily extendable to add more recurring operations.
The template includes unit tests for domain logic, integration tests for buses and persistence, and E2E tests for API routes. Coverage is high and test structure is clean.
Routes and commands can be restricted by roles using a flexible RBAC system. Each user has permissions mapped to their role and access is enforced at runtime.
Built with TypeScript strict mode, Zod validation, ESLint, and Prettier. You get clean, safe, and readable code from day one.
No hidden magic. Every part of the system is explicit, composable, and replaceable. You have full ownership of how your app behaves.
Full documented. Each section has his own md file explaining folder structure and decisions
Most templates are incomplete toys that teach bad habits. Here's what you're really getting vs. what you need.
Missing authentication, error handling, and production concerns
Basic CRUD with no real-world complexity or edge cases
Spaghetti code that doesn't scale beyond the demo
No updates, no support, no community
Result: You waste weeks trying to make it production-ready, only to start over.
Complete with auth, validation, error handling, and monitoring
DDD, CQRS, and patterns that scale to millions of users
Used in production by real companies with real users
Continuous updates, community, and expert guidance
Result: Deploy to production in days, not months. Scale confidently.
Most developers spend months building infrastructure instead of features. With DomusJS, you get enterprise-grade architecture out of the box.
While this template demonstrates video processing, the architecture patterns you'll learn are universally applicable to any domain or industry.
Apply the same patterns to build order processing, inventory management, payment systems, and customer analytics.
Scale user management, content feeds, real-time messaging, and recommendation systems with the same principles.
Build multi-tenant systems, subscription management, feature flags, and usage analytics using identical patterns.
Process data streams, generate reports, handle real-time dashboards, and scale data pipelines with the same architecture.
Orchestrate model training, inference pipelines, data preprocessing, and model serving using the same scalable patterns.
The core principles — CQRS, DDD, job queues, authentication, and observability — work for any business domain.
The video processing domain is just the vehicle.What you're really learning is how to build production-ready, scalable systems that can handle any business logic.
