Custom libraries & SDKs
Typed API clients, domain libraries, integration adapters, and internal packages. Semantic versioning, dependency management, and automated compatibility checks support predictable upgrades.

// Handle documented errors and retry rules.What the package should clarify
- Authentication configuration
- Typed request and result models
- Timeout and retry behavior
- Stable error categories
An internal library is a product for other developers. Its documentation, compatibility policy, and release notes matter as much as the implementation. Reuse is valuable when it reduces ambiguity instead of hiding important behavior.
Version the promise, not just the package
| Change | Consumer impact |
|---|---|
| New optional helper | Document it and keep existing behavior stable. |
| Changed default timeout | Explain the operational effect and test slow requests. |
| Removed argument or result field | Plan a breaking change and a migration path. |
How do you keep an SDK from becoming a second application?
Keep domain decisions in the owning service where possible. The SDK should express its contract clearly, not duplicate business rules that drift between consumers.
