The instructions your model reads when the skill loads.
Patterns for creating high-performance AWS Lambda functions in TypeScript with optimized cold starts.
Two approaches for TypeScript Lambda:
Both support API Gateway and ALB integration.
| Approach | Cold Start | Bundle Size | Best For | Complexity |
|---|---|---|---|---|
| NestJS | < 500ms | Larger (100KB+) | Complex APIs, enterprise apps, DI needed | Medium |
| Raw TypeScript | < 100ms | Smaller (< 50KB) | Simple handlers, microservices, minimal deps | Low |
