Engineering-First Library Documentation
Professional documentation doesn't just list methods; it builds a mental model for the consumer. This template is designed for libraries that prioritize performance, clarity, and developer experience.
Focus on the Why in your Overview and the Edge Cases in your API reference. That is where users actually get stuck.
Documentation Sections
The Mental Model #
Explain the core philosophy of this library. Is it functional? Declarative? Does it favor configuration over convention?
Core Pillars:
- Zero-Dependency Core: Only 2kb gzipped, no bloat.
- Type Safety: Built with TypeScript from day one for excellent IDE intellisense.
- Pluggable Architecture: Extend functionality via middleware or hooks.
Info
Note: If you are migrating from v1.x, please see the Migration Guide before proceeding, as there are breaking changes in the initialization sequence.
Architecture & Data Flow #
Provide a high-level overview of how data moves through the library.
- Input: Raw stream or JSON payload.
- Processing: Immutable transformations in the internal engine.
- Output: Validated schema or standard event emitter.
