I have a REST client on node, and I'm trying to upload pdf a file to another REST webserver which provides the ability to parse my pdf and extract some data. Basically it is a service. The npm package that I use is: . If there are other rest clients, I can use those as well. The rest api I need to use is described below:

POST    /         ; Uploads a new PDF document via a form <br>
POST    /file     ; Uploads a new PDF document via bytestream

The question is how to upload the file. Also, I would like to see how to store the file at the other end.

You can use npm module request to upload the file. Here is a working example

var request = require('request');
var fs = require('fs');
request({
  method: 'PUT',
  preambleCRLF: true,
  postambleCRLF: true,
  uri: 'http://yourdomain/file',
  multipart: [
    {
      'content-type': 'application/pdf',
      body: fs.createReadStream('image.png') 
    }
  ]    
},
function (error, response, body) {
  if (error) {
    return console.error('upload failed:', error);
  }
  console.log('Upload successful!  Server responded with:', body);
});

For receiving at the server side with node you can use modules like busboy. Here is a demo for this

var busboy = require('connect-busboy');
app.use(busboy());
app.use(function(req, res) {
  if (req.busboy) {
    req.busboy.on('file', function(fieldname, file, filename, encoding,    mimetype) {
      // move your file etc
    });
    req.pipe(req.busboy);
  }
});

You can use request.

There is an example for that

fs.createReadStream('file.pdf').pipe(request.post('http://example.com/file'))
