AWS S3 Stream Uploader

Overview

This package provides a convenient way to upload data streams, such as files, to Amazon S3 (Simple Storage Service) and generate signed URLs for accessing the uploaded content. It's particularly useful for scenarios where you need to upload large files or streams to S3 and share them securely with others.

Installation

You can install this package via npm:

npm install @imrandil/aws-s3-stream-uploader

Usage

To use this package, follow these simple steps:

• Import the package:

const { uploadStreamToS3, getObjectURL, getURLAfterUploadToS3 } = require('@imrandil/aws-s3-stream-uploader');

• Configure your AWS S3 credentials:

const s3Config = {
    region: 'your-region',
    credentials: {
        accessKeyId: 'your-access-key-id',
        secretAccessKey: 'your-secret-access-key'
    }
};

• Upload a stream to S3:

const stream = /* Your data stream */;
const bucket = 'your-bucket-name';
const key = 'your-file-key';
const expiresIn = 900; // Expiry time in seconds
const contentType = 'application/pdf'; // Set the content type dynamically
try {
    await uploadStreamToS3(s3Config, bucket, key, stream, contentType);
    console.log('Stream uploaded successfully');
} catch (error) {
    console.error('Error uploading stream to S3:', error);
}

• Generate a signed URL for the uploaded content:

const signedURL = await getObjectURL(s3Config, bucket, key, expiresIn);
console.log('Signed URL:', signedURL);

• Or, combine both steps to get the signed URL after uploading:

try {
    const contentType = 'application/pdf'; // Set the content type dynamically
    const { success, signedURL } = await getURLAfterUploadToS3(s3Config, bucket, key, stream, expiresIn, contentType);
    console.log('Signed URL:', signedURL);
} catch (error) {
    console.error('Error in getURLAfterUploadToS3:', error);
}
