Pause and Resume

Demo uploads land in a temporary store and are swept after 60 minutes. To keep files, handle FileUploaded — see Single File for the complete save pattern.

Pause and Resume Uploads

Pause an active upload and resume it later. The upload continues from where it left off, making it ideal for large files on unreliable connections.

What you should see: pause mid-upload and the transfer genuinely stops (1 MB chunks make that cheap); resume continues from the last completed chunk, not from zero.

// Pause: uploader.pauseAll();
// Resume: uploader.resumeAll();
