hyperdrive-import-queue

hyperdrive-import-queue

Takes an array of files, chunks and writes them to a hyperdrive archive. onFileWriteBegin callback returns each file object with a progress listener that emits file write progress info as each file is written. Progress info provided via progress-stream.

TODO: rabin-ify the chunks for non-browser hyperdrive imports.

Usage

arguments:

• @files: array of files to import/write to archive
• @archive: hyperdrive archive
• @options: object -- see below

hyperdriveImportQueue(files, archive, {
  cwd: '',               // defaults to ''
  progressInterval: 100, // defaults to 100ms
  chunkSize: 4*1024,     // defaults to 4*1024
  onQueueNewFile: function (err, file) {
    // add file to your queue UI
  },
  onFileWriteBegin: function (err, file) {
    // you may now start incrementing your progress bar UI at this point
    // by attaching your progress listener callback to the `progress` event:
    file.progressListener.on('progress', function (progress) {
     // increment your progress bars here using the `progress` argument data
    })
  },
  onFileWriteComplete: function (err, file) {
    // a single file has now been written to the hyperdrive archive
    // the next file in the queue will start writing and trigger a new
    // `onFileWriteBegin` callback to fire
  },
  onCompleteAll: function (err, files) {
    // do whatever you like
  }
})
