Introduction
AWS Lambda is a serverless compute service that runs code in response to events.
Getting Started
typescript
import { APIGatewayProxyEvent, APIGatewayProxyResult } from 'aws-lambda';
export const handler = async (
event: APIGatewayProxyEvent
): Promise<APIGatewayProxyResult> => {
return {
statusCode: 200,
body: JSON.stringify({ message: 'Hello from Lambda!' })
};
};Cold Start Optimization
typescript
// Keep functions warm
export const keepWarmHandler = async () => {
console.log('Keeping warm...');
return { statusCode: 200 };
};
// Schedule every 4 minutesConclusion
AWS Lambda enables powerful serverless architectures.
