What this skill does
AWS Serverless Patterns Lambda Handler Pattern Proper Lambda function structure with error handling When to use: ['Any Lambda function implementation', 'API handlers, event processors, scheduled tasks'] javascript // Node.js Lambda Handler // handler.js // Initialize outside handler (reused across invocations) const { DynamoDBClient } = require('@aws-sdk/client-dynamodb'); const { DynamoDBDocumentClient, GetCommand } = require('@aws-sdk/lib-dynamodb'); const client = new DynamoDBClient({}); const docClient = DynamoDBDocumentClient.from(client); // Handler function exports.handler = async (event, context) => { // Optional: Don't wait for event loop to clear (Node.js) context.callbackWaitsForEmptyEventLoop = false; try { // Parse input based on event source const body = typeof event.body === 'string' ? JSON.parse(event.body) : event.body; // Business logic const result = await processRequest(body); // Return API Gateway compatible response return { statusCode: 200, headers: { 'Content-Type': 'application/json', 'Access-Control-Allow-Origin': '' }, body: JSON.stringify(result) }; } catch (error) { console.error('Error:', JSON.stringify({ error: error.message, stack: error.stack, requestId: context.awsRequestId })); return { statusCode: error.statusCode 500, headers: { 'Content-Type': 'application/json' }, body: JSON.stringify({ error: error.message 'Internal server error' }) }; } }; async function processRequest(data) { // Your business logic here const result = await docClient.send(new GetCommand({ TableName: process.env.TABLENAME, Key: { id: data.id } })); return result.Item; } python Python Lambda Handler handler.py import json import os import logging import boto3 from botocore.exceptions import ClientError Initialize outside handler (reused across invocations) logger = logging.getLogger() logger.setLevel(logging.INFO) dynamodb = boto3.resource('dynamodb') table = dynamodb.Table(os.environ['TABLENAME']) def handler(event, context): try: # Parse i javascript Event-D …
