React Hooks (introduced in 16.8) are now the standard. Class components with `this.setState` and lifecycle methods are legacy. This guide provides direct translation patterns for migrating typical class components to functional components with Hooks. State Management: useState Lifecycle: useEffect `useEffect` replaces `componentDidMount`, `componentDidUpdate`, and `componentWillUnmount`. Common Pitfall: Stale Closures Hooks capture the state *at the […]

AWS CloudFormation Best Practices
Even with tools like CDK, understanding the underlying CloudFormation mechanics is crucial. Improperly structured stacks can lead to circular dependencies, update rollbacks, and stuck resources. This guide covers nested stacks, cross-stack references, and drift detection. Cross-Stack References vs Nested Stacks Feature Cross-Stack Refs (Export/Import) Nested Stacks Coupling Loose (Independent lifecycles) Tight (Parent controls Child) Updates […]

CloudFormation YAML is verbose and lacks logic. The AWS Cloud Development Kit (CDK) allows you to define cloud resources using imperative languages. In this guide, we build a complete serverless stack (Lambda + API Gateway + DynamoDB) using TypeScript. The Construct Tree CDK components are called “Constructs”. Level 1 (L1) constructs are 1:1 mappings to […]
