Installation

yarn add aws-lambda-log-wrapper

OR

npm i aws-lambda-log-wrapper

Usage

import { AwsLambdaLogWrapper } from 'aws-lambda-log-wrapper';
import { STSClient, GetCallerIdentityCommand } from '@aws-sdk/client-sts';
import { LambdaLog } from 'lambda-log';

const log = new LambdaLog();

new STSClient({ logger: new AwsLambdaLogWrapper(log) }).send(new GetCallerIdentityCommand({}))
