go-resumable

It's a Go library providing multiple simultaneous and resumable uploads.

Library is designed to introduce fault-tolerance into the upload of large files throught HTTP. This is done by splitting each file into small chunks; whenever the upload of a chunk fails, uploading is retried until the procedure completes. This allows uploads to automatically resume uploading after a network connection is lost either locally or to the server. Additionally, it allows users to pause, resume and even recover uploads without losing state.

Demo

In this demo upload is paused for 2 seconds after initial second, then it uploads till 100%.

Please check here for full code sample.
