Read a large document with the marklogic Nodejs API

I am trying to read xml / json docs using Node.js from MarkLogic. I downloaded the Node.js API database from the following url.

https://github.com/marklogic/node-client-api

It works great for small documents like 500KB. But our requirement is to read large documents, for example 2 MB or 10 MB.

Due to this, we have two cases as below: -

Case 1: - Whenever I try to read a document using the MarkLogic Node.js API I should get more than one fragment, but I only got one fragment as a response. Therefore, for this reason, it does not work.

var chunks = 0;
var length = 0;
db.documents.read("test.xml").stream('chunked').
  on('data', function(chunk) {
    console.log(chunk);
    console.log(chunk.length);
    chunks++;
    length += chunk.length;
  }).
  on('error', function(error) {
    console.log(JSON.stringify(error));
  }).
  on('end', function() {
    console.log('read '+chunks+' chunks of '+length+' length');
    console.log('done');
  });

      

        
        
        
      

    

Case 2: - When I try to read some large document (like 2MB or 10MB) using the "http-digest-client" package, it works fine and I get the full xml as a response.

var digest = require('http-digest-client')('<Username>', '<password>');
digest.request({
  host: '<Host server>',
  path: '/v1/documents?uri=test.xml',
  port: 8007,
  method: 'GET',
}, function (res) {
  reply(res);
});

      

        
        
        
      

    

I tested this with a large document in the example below (see url below), but I get the same answer I described in case 1 above.

As per my requirement, I would like to read a large document using the MarkLogic Node.js API (case 1).

• How can I read a large document using the MarkLogic Node.js API?
• Is it possible to increase the pool memory size or any other memory size?
• Is this problem related to memory size?
