Aws Serverless

This covers the essentials for building serverless apps on AWS with Lambda, API Gateway, DynamoDB, and event-driven patterns using SQS/SNS. You get proper handler structures for both Node.js and Python, SAM templates for API Gateway integration, and batch processing patterns with partial failure handling. The sharp edges section calls out cold start issues and gives you concrete fixes like measuring INIT phase and tuning memory allocation. It's Apache 2.0 licensed from vibeship-spawner-skills. Honestly, the anti-patterns section could use more depth, but the code examples are solid and cover the stuff you'll actually need when wiring together a production serverless API.

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);
