TypeError: XMLHttpRequest is not a function when using web3 on meteor server side

I get the error TypeError: XMLHttpRequest is not a function when I try to interact with a contract on the server side of my meteor application.

web3 = new Web3(new Web3.providers.HttpProvider("http://localhost:8545"))

var cocontract = web3.eth.contract(abi).at(address);
var name = (cocontract.name())

The error is raised with the 3rd line. If I run the same code on the client side I don't get a problem.

I had the same problem. Instead ethereum:web3 Meteor package I have used [email protected] NPM package, and it works ok (Meteor version 1.5.1). So, if you using ethereum:web3 you probably need to run:

meteor remove ethereum:web3
meteor npm install [email protected] --save

and replace

import { Web3 } from 'meteor/ethereum:web3';

with

import Web3 from 'web3';

I haven't used web3, but I suspect it's taking advantage of the XMLHttpRequest, which is only present in browsers. Try getting an analogue for that on the server. I'd start with this one: xmlhttprequest
