xhr-progress

Get progress updates for your XMLHttpRequests where supported.

Usage

progress(xhr)

Returns an EventEmitter that emits progress events for the XMLHttpRequest passed into the first argument.

progress.on('data', handler(amount, total))

Emitted for each progress update. amount is a number between 0 and 1 representing how much of the request has been completed. total is the total size of the request.

If progress events are not available, total will default to null, and this event will be emitted once the request is complete with an amount of 1.

progress.on('end', handler())

Called when the request is complete.
