Correlation Ids for aws-lambda-powertools

Features

1. Middleware to enable injecting correlation ids from the request into the AsyncLocalStorage

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)

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 AsyncLocalStorage: getCorrelationIds()

import { useCorrelationIds } from '@aws-lambda-powertools-correlation';

const correlationIds = useCorrelationIds();
