Library for uploading large files chunked

This is a library containing a collection of utilities for uploading large files.

The main utilities are:

  • prepareFile(): Will read a supplied file and create a list of chunks from it. Each chunk will be provided with a SHA-1 checksum. The function is working asynchroneously, as it might take a long time, depending on the size of the file and the browser the user is using. An EventEmitter is returned which will emit different usefull events during the whole process.
  • upload(): Will consume the list of chunks generated by prepareFile() and transfer each chunk to the backend. Will provide each chunk with a transfer status. This function also returns an EventEmitter which will emit relevant events during the transfer.
