S3Handler

Description

S3Handler is a package meant to simplify the handeling of S3 messages. It does automatic JSON parsing/stringifying of the message's body, attiributes composition and parsing of message's attributes. This package has a peer-dependency on the AWS sdk v3.

import { S3Handler } from '@sagacify/s3-handler';

const s3Client = new S3Client({ region: 'eu-west-1' });

const s3Handler = new S3Handler(s3Client, 'my-bucket-name');

// Get object
await s3Handler.getObject('my-key');

// Put object
await s3Handler.putObject('my-key', Buffer.from('hello-world'));
