Feature architecture determines code organization, from API design to component structure. Each feature requires distinct approaches to security, real-time updates, and testing strategies. Our collection features boilerplates with production-ready implementations of common SaaS features following architectural best practices.
Feature-specific boilerplates provide layered architecture with clear separation of concerns, implement defense-in-depth security (input validation, XSS prevention, rate limiting), include API design patterns (RESTful endpoints, pagination, filtering), and provide comprehensive testing suites (unit, integration, E2E). Each feature follows architectural principles for maintainability and extensibility.
Browse our collection of 113 features boilerplates to find the perfect starting point for your next SaaS project. Each boilerplate has been carefully reviewed to ensure quality, security, and production-readiness.
Features follow layered architecture: API routes handle HTTP requests, service layers contain business logic, repositories manage data access, and UI components provide the interface. Each feature includes proper separation of concerns, dependency injection, and modular design for maintainability.
Security implementations include input validation with schema libraries, SQL injection prevention through parameterized queries, XSS protection via output encoding, CSRF token validation, rate limiting per feature, role-based access control, audit logging, and security headers. All features follow OWASP Top 10 mitigation strategies.
Real-time features use WebSockets (Socket.io, native WebSocket API), Server-Sent Events for one-way updates, or optimized polling. Implementations include connection authentication, automatic reconnection, message queuing, presence detection, and horizontal scaling support through Redis pub/sub or similar solutions.
API patterns include RESTful design with proper HTTP verbs, resource-based URLs, and status codes. Features support pagination (cursor or offset-based), filtering, sorting, field selection, and include comprehensive error handling. Many include GraphQL alternatives with type-safe schemas, resolvers, and batching.
Testing implementations include unit tests for business logic, integration tests for APIs and databases, and E2E tests for user flows. Each feature uses appropriate testing frameworks (Jest, Vitest, Pytest, RSpec) with mocking, fixtures, and CI/CD integration. Tests cover functional requirements, error handling, and security scenarios.
