The demo runs out of space if we don't remove the files in the upload folder. We used to do this using the find-remove package.

findRemoveSync = require('find-remove');

// Remove files older than 1 hour every hour.
setInterval(function() {
  var removed = findRemoveSync(__dirname + '/../uploads', { age: { seconds: 3600 } });
  if (removed.length > 0) {
    console.log('removed:', removed);
  }
}, 3600000);

We need to convert document without having to persisting them.
@Lhuihui we probably want to send the file and the output in one request as a form submission.

The nodejs-wrapper supports document conversion of files that were not uploaded to the service.

Is possilbe increase size to 10 mb?

When I pick my own PDF file on the official demo it gets converted beautifully. However, when I follow the instructions, only the sample documents work, but when I upload my own file I get the following errors in my log:

2015-11-25T04:40:07.38+0100 [App/0] OUT error: { code: 'ENOENT',
2015-11-25T04:40:07.38+0100 [App/0] OUT error: 'ENOENT, open 'uploads/1448422807362-Survey of Text Clustering Algorithms.pdf'' } url: /files
[...]
2015-11-25T04:40:07.58+0100 [App/0] OUT error: { code: 'ENOENT',
2015-11-25T04:40:07.58+0100 [App/0] OUT error: 'ENOENT, no such file or directory '/home/vcap/app/uploads/'' } url: /api/convert?document_id=&conversion_target=NORMALIZED_TEXT

Any help to solve this would be highly appreciated. Thanks in advance.

Best,
Joe
