Tech Starters

🚀 What is a Tech-Starter?

A Tech-Starter is a ready-to-use technical building block (library, service) that you can pick off the shelf to integrate into a business project without mixing technical concerns with business logic.

Its goals are to:

• Provide cross-cutting technical features (auth, logs, security, caching, monitoring, ...) without requiring business developers to handle their technical implementation.
• Enable teams to focus on business value while ensuring quality, consistency, and maintainability of technical concerns.

When adopted with discipline, they help build robust, standardized, and maintainable applications for the long term.

🎯 Objectives

• Technical isolation: business code does not depend on technical implementation details.
• Plug & Play: easy to add or remove from a project.
• Internal mutability: the behavior of a Tech-Starter can evolve without impacting business code.
• Technical consistency: standardizes cross-cutting practices across projects or the organization.
• Acceleration: reduces time-to-market by avoiding reinventing essential technical blocks.

Tech-Starters Examples

• Security: JWT, OAuth2, RBAC, CSRF token
• Structured Logging: standardized, traceable logs
• Tracing & Monitoring: built-in OpenTelemetry
• Error Management: standardized error responses
• Retry / Circuit Breaker: resilience management
• Distributed Cache: fallback, invalidation
• Database: datasource configuration

🌟 Benefits

✅ Faster development
✅ Consistency across projects
✅ New projects quickly ready for production with all requirements

⚖️ Known Limitations

⚠️ Introduces abstraction requiring learning conventions.
⚠️ Some boilerplate may be needed for clean integration.
⚠️ Risk of over-engineering if overgeneralized.

🗒️ Best Practices

✅ Expose simple interfaces (hook, middleware, service)
✅ Allow parameter-based configuration
✅ Provide clear documentation with examples
✅ Include unit and E2E tests
✅ Maintain backward compatibility or clean versioning
