Implement large file downloads with StreamSaver.js in JavaScript. Overcome browser limitations and enhance your web applications efficiently.

If you use the blob object for browser-side file downloads and then call the URL.createObjectURL(blob) method, the file will be downloaded directly. However, the downside is that it only supports small file downloads. How can we solve this without changing the backend? StreamSaver.js was created to address this issue.

Principle

StreamSaver.js uses ServiceWorker to intercept requests. If the result of the request is a stream, it can be continuously written to the local browser side. This breaks the limitation of JS single-thread, allowing large file downloads without blocking the thread.

const fileStream = streamSaver.createWriteStream('hello.mkv', { size: 10_000_000 });
const fileWriter = fileStream.getWriter();

fileWriter.write(new Uint8Array(chunk));

fileWriter.close();
