Blob Stream is a powerful tool for handling binary large objects (BLOBs) and streaming data in web applications. It provides a range of APIs for manipulating and working with BLOBs, which allows developers to create seamless and efficient data streaming solutions. In this guide, we will cover several useful Blob Stream APIs with code snippets and an app example demonstrating their usage.

Introduction to Blob Stream

Blob Stream enhances the way you manage and interact with large binary files over a network. Whether it’s uploading or downloading large files, or streaming video and audio content, Blob Stream provides the flexibility and efficiency needed to handle these operations seamlessly.

API Overview

• Creating a Blob Stream

    const stream = blobStream();
    

• Appending Data to the Stream

    stream.append(buffer);
    

• Finalizing the Stream and Getting a Blob

    stream.finalize(function(err, blob) {
        if (err) console.error(err);
        else console.log('Blob available:', blob);
    });
    

• Handling Stream Errors

    stream.on('error', function(err) {
        console.error('Stream error:', err);
    });
    

• Pausing and Resuming the Stream

    stream.pause();
    stream.resume();
