Answer 1

It is not compulsory that you need node sdk to connect with hyperledger. You can easily connect with hyperledger composer through node.Than you can easily write a node code to connect two Peers Easily

    var request = require('request');

var headers = {
    'Content-Type': 'application/json',
    'Accept': 'application/json'
};

var dataString = '{ \ 
   "$class": "test.User", \ 
   "uid": "01", \ 
   "firstName": "Prateek", \ 
   "lastName": "Tiwari", \ 
   "emailAddress": "prat%40", \ 
   "contactNo": "789", \ 
   "password": "7596.." \ 
 }';

var options = {
    url: 'http://localhost:3000/api/test.User',
    method: 'POST',
    headers: headers,
    body: dataString
};

function callback(error, response, body) {
    if (!error && response.statusCode == 200) {
        console.log(body);
    }
}

request(options, callback);
