Features

1. Middleware to enable injecting correlation ids from the request into the AsyncLocalStorage
``typescript
import { enableCorrelationIds } from 'aws-lambda-powertools-correlation';
import middy from '@middy/core';
import * as Lambda from 'aws-lambda';

export const handler = (_handler: Lambda.APIGatewayProxyHandlerV2) => {
return middy(_handler).use(enableCorrelationIds());
};
`


2. Utility to extend the powertools logger with correlation ids: injectCorrelationIds(logger)

`typescript
import { injectCorrelationIds } from 'aws-lambda-powertools-correlation';
import { Logger } from '@aws-lambda-powertools/logger'

const logger = new Logger();

export const handler = (_handler: Lambda.APIGatewayProxyHandlerV2) => {
return middy(_handler)
.use(enableCorrelationIds())
.before(() => { injectCorrelationIds(logger) });
};
`

3. Utility to get correlation ids from the internal store: getCorrelationIds()
`typescript
import { useCorrelationIds } from 'aws-lambda-powertools-correlation';

const correlationIds = useCorrelationIds();
