@types/aws-lambda
Advanced tools
The @types/aws-lambda package provides TypeScript type definitions for AWS Lambda. This allows developers to write Lambda functions in TypeScript with type checking, making development more robust and error-free. It covers various AWS Lambda event sources such as API Gateway, S3, DynamoDB, and more, providing types for event objects, context, and handler responses.
API Gateway Proxy Handler
Defines a handler for AWS Lambda functions triggered by an API Gateway event, allowing you to process HTTP requests and return responses.
import { APIGatewayProxyHandler } from 'aws-lambda';
export const handler: APIGatewayProxyHandler = async (event, context) => {
return {
statusCode: 200,
body: JSON.stringify({ message: 'Hello from Lambda!' }),
};
};
S3 Event Handler
Provides types for handling S3 bucket events, such as object creation or deletion, enabling you to react to changes in S3 buckets.
import { S3Handler } from 'aws-lambda';
export const handler: S3Handler = async (event, context) => {
console.log('S3 event:', event);
// Process S3 event
};
DynamoDB Stream Handler
Facilitates the processing of DynamoDB stream events, allowing you to handle changes in DynamoDB tables in real-time.
import { DynamoDBStreamHandler } from 'aws-lambda';
export const handler: DynamoDBStreamHandler = async (event, context) => {
console.log('DynamoDB Stream event:', event);
// Process DynamoDB stream records
};
While not a direct alternative, the aws-sdk package is often used alongside @types/aws-lambda for interacting with AWS services within Lambda functions. It provides JavaScript objects for AWS services but does not offer TypeScript types for Lambda events.
The serverless framework helps you build serverless applications using AWS Lambda and other providers. It abstracts away some of the complexities of deploying and managing Lambda functions but does not provide TypeScript definitions for Lambda events.
This is the JavaScript SDK for AWS Lambda, allowing you to write Lambda functions. However, it does not provide TypeScript type definitions, which is where @types/aws-lambda comes in to complement it by offering types for better development experience in TypeScript.
