Upload files to gridFS server side using vsivi:file-collection meteor package

uploadGridFS.js

uploadImage = function (itemCode) {
  // get the image link
  var image = Meteor.call('getImageLink', itemCode)
  
  // Upload to gridFs (vsivi:file-collection)
  var imageStream = fc.upsertStream({ filename: itemCode + '.jpg',
    contentType: 'image/jpeg',
    metadata: {}
  })

  // pipe the image request to gridFs
  var requestImage = request(image)
  requestImage.pipe(imageStream)

  // object for filesystem (prevent corruption (The same style that Orionjs uses))
  var filesystem = {
    url: '/gridfs/data/id/' + imageStream.id,
    meta: { gridFS_id: imageStream.id },
    name: itemCode + '.jpg',
    uploader: 'Server',
    uploadedBy: 'Joadr-server'
  }
  
  // Insert the image data on collection
  var fileId = orion.filesystem.collection.insert(filesystem)

  return {
    fileId: fileId,
    url: '/gridfs/data/id/' + imageStream.id,
    info: {}
