5	### Lambda Handler Pattern
6
7	Proper Lambda function structure with error handling
8
9	When to use: ['Any Lambda function implementation', 'API handlers, event processors, scheduled tasks']
10
11	```python
12	```javascript
13	// Node.js Lambda Handler
14	// handler.js
15
16	// Initialize outside handler (reused across invocations)
17	const { DynamoDBClient } = require('@aws-sdk/client-dynamodb');
18	const { DynamoDBDocumentClient, GetCommand } = require('@aws-sdk/lib-dynamodb');
19
20	const client = new DynamoDBClient({});
21	const docClient = DynamoDBDocumentClient.from(client);
22
23	// Handler function
24	exports.handler = async (event, context) => {
25	// Optional: Don't wait for event loop to clear (Node.js)
26	context.callbackWaitsForEmptyEventLoop = false;
27
28	try {
29	// Parse input based on event source
30	const body = typeof event.body === 'string'
31	? JSON.parse(event.body)
32	: event.body;
33
34	// Business logic
35	const result = await processRequest(body);
36
37	// Return API Gateway compatible response
38	return {
39	statusCode: 200,
40	headers: {
41	'Content-Type': 'application/json',
42	'Access-Control-Allow-Origin': '*'
43	},

50	requestId: context.awsRequestId
51	}));
52
53	return {

56	body: JSON.stringify({
57	error: error.message \|\| 'Internal server error'
58	})
59	};
60	}
61	};
62
63	async function processRequest(data) {
64	// Your business logic here
65	const result = await docClient.send(new GetCommand({
66	TableName: process.env.TABLE_NAME,
67	Key: { id: data.id }
68	}));
69	return result.Item;
70	}
