aws-s3-browser-multipart-uploader

Upload large files in multipart from browser.

This implementation is heavily inspired by s3-multipart-upload-browser.

Features

1. Multi-parts upload, files are sliced into chunks and each chunk is uploaded separately. So the uploading progress can be paused and resumed. If one chunk is fail, it can be retried later without failing the whole file upload.

2. Multi file upload support, files can be uploaded concurrently. So small files don't need to wait for the large files to complete the upload.

3. Smooth progress bar. The upload progress can be captured to byte level. So a smooth upload progress bar can be implemented.

Browser Support

Browsers that support html5 file.slice API.

Chrome 6+, FF 4+, and IE 10+
