Aws Cdk

Solid foundation for building AWS infrastructure with CDK in TypeScript. Walks you through the full loop: init, stack modeling, synth, diff review, deploy, and testing with fine-grained assertions. The construct level breakdown (L1/L2/L3) is practical, and the delivery checklist actually maps to what breaks in real projects like unresolved references, risky diffs, and bootstrap issues. Examples cover serverless APIs with DynamoDB and Lambda, cross-stack VPC wiring, and environment-aware deployments. The emphasis on reviewing diffs before deploy and using grant helpers over handwritten IAM is the right default. Treats cdk synth and cdk diff as mandatory checkpoints, which they should be.

AWS CDK TypeScript

Overview

Use this skill to build AWS infrastructure in TypeScript with reusable constructs, safe defaults, and a validation-first delivery loop.

When to Use

Use this skill when:

Creating or refactoring a CDK app, stack, or reusable construct in TypeScript
Choosing between L1, L2, and L3 constructs
Building serverless, networking, or security-focused AWS infrastructure
Wiring multi-stack applications and environment-aware deployments
Validating infrastructure changes with cdk synth, tests, cdk diff, and cdk deploy
