jimmywarting/StreamSaver.js

Features

• Browser Writable Stream Libraries - Provides a JavaScript library that writes data streams directly to the local filesystem to avoid browser memory exhaustion.
• Streamed Writes - Creates a writable stream that sends generated data directly to the filesystem to handle large files.
• Browser-Side Data Export - Exports massive datasets generated in the browser directly to the local filesystem to avoid browser crashes.
• Browser Download Streaming - Processes continuous data streams in the browser to trigger file downloads before the full payload is buffered.
• Browser-to-File Streaming - Implements a mechanism to stream data chunks directly into a downloadable file to prevent browser memory overflow.
• Large-File Download Triggers - Saves large amounts of generated data to the local disk without crashing the browser due to memory exhaustion.
• Client-Side Stream Buffering - Passes data chunks through the browser pipeline immediately to avoid heap overflow during large file saves.
• Direct-to-File Response Saving - Writes generated data streams directly to the filesystem to minimize memory overhead.
• Client-Side File Savers - Provides a mechanism for saving large generated files or media recordings to disk without buffering the entire payload in RAM.
• File Streaming - Converts browser streams into downloadable files by bypassing the standard blob-based save approach.
• Web Streams API Integrations - Uses the standard Web Streams API to pipe data from a source to a filesystem destination without buffering.
• Large Data Streamers - Handles massive data streams by writing them directly to the filesystem to avoid exhausting memory.
• Media Stream Recording - Writes real-time audio and video captures directly to the local filesystem to prevent memory exhaustion.
• Real-Time Recording Persistence - Writes live audio or video streams directly to the filesystem to prevent memory overflow during capture.
• Download Proxying - Intercepts fetch requests via a service worker to pipe streamed responses directly into a browser download.
• Fetch-Based Download Loopbacks - Creates a local URL that triggers a browser download by looping a stream back through a fetch request.
