xform-uploader

Parse a set of XForms and attachments, and upload them to an odk-aggregate server or osm-p2p + hyperdrive.

Example

var uploader = new Uploader()

uploader.add([
  xmlFile1,
  attachment1,
  attachment2,
  xmlFile2,
  attachment4,
  attachment5
], function (err) {
  console.log(uploader.state())
})

// output:
{
  forms: [
    {
      data: parsedFormAsGeoJSON,
      uploaded: 0 // 0-1 progress uploaded, 1 === upload complete
      attachments: [
        {
          filename: 'originalFilename.jpg',
          mediaId: '1231421531.jpg', // not set on attachments until after upload
          blob: attachment1,
          uploaded: 1
        }, {
          filename: 'originalFilename2.jpg',
          mediaId: null,
          blob: attachment2,
          uploaded: 0
        }
      ]
    }
  ],
  missingAttachments: [
    // A form references this media, but the media itself has not been provided.
    'originalFilename3.jpg'
  ],
  orphanAttachments: [
    // This media was provided, but no form references it.
    'otherFilename.png'
  ]
}

// fires every time the internal state changes
uploader.on('change', function () { console.log(uploader.state()) })

uploader.upload({
  observationUpload: 'http://localhost:4001/obs/create',
  mediaUpload: 'http://localhost:4002/media/jpg'
})

API

var Uploader = require('xform-uploader')
var uploader = new Uploader()

uploader.add(files, done)

Add an array of Files to the uploader. Once complete, the callback done will be called with the form function (err).

uploader.state()

Synchronously return the instantaneous state of the Uploader as an object. It will have the following structure:

{
  forms: [
    {
      data: parsedFormAsGeoJSON,
      uploaded: 0 // 0-1 progress uploaded, 1 === upload complete
      attachments: [
        {
          filename: 'originalFilename.jpg',
          mediaId: '1231421531', // or 'null' until uploaded
          blob: attachment1,
          uploaded: 1
        }, {
          filename: 'originalFilename2.jpg',
          mediaId: null,
          blob: attachment2,
          uploaded: 0
        }
      ]
    }
  ],
  missingAttachments: [
    // A form references this media, but the media itself has not been provided.
    'originalFilename3.jpg'
  ],
  orphanAttachments: [
    // This media was provided, but no form references it.
    'otherFilename.png'
  ]
}

uploader.on('change', function () { ... })

This event is emitted whenever the public-facing state of the Uploader has changed.

uploader.upload(servers, done)

Upload the forms and their attachments to various servers.

servers is an object. Currently the following keys are accepted:

observationsUrl: an HTTP URL of a POST endpoint to receive the osm observation data that each form represents.
mediaUrl: an HTTP URL of a POST endpoint to receive the media data that each attachment represents.

Inner Modules

This module contains two inner modules: FormSet and XFormSet, which are more general purpose and may useful outside of the context of the outer module, which is just a small amount of glue code.
