What is Resumable.js?

Editorial review
Resumable.js is a JavaScript library that provides a stable and resumable upload process for web applications. It achieves this by splitting large files into smaller chunks, uploading them independently, and then reassembling them on the server. This chunking mechanism allows uploads to be paused, resumed, and recovered from network interruptions or browser crashes without losing progress. This library is ideal for developers who need to implement reliable file upload functionality, especially for large files, in their web applications. It simplifies the complexity of handling partial uploads, retries, and progress tracking, providing a smoother user experience and reducing frustration caused by failed uploads. By abstracting away the low-level details of chunking and retries, Resumable.js enables developers to focus on integrating robust file uploads into their projects with minimal effort.
