XMLHttpRequest is not defined

[mindrones]

Hi, this script:

var d3 = require('d3');
d3.json('https://nodejs.org/api/all.json', function(err, json) {})

returns:

/path/to/node_modules/d3/build/d3.js:4438
          xhr = new XMLHttpRequest,
                    ^
ReferenceError: XMLHttpRequest is not defined
    at request (/path/to/node_modules/d3/build/d3.js:4438:18)

XMLHttpRequest is not defined in Node.js. The d3-request library has a polyfill for it, but that polyfill does not extend to the d3 bundle. I suppose it should, but this issue should be filed in mbostock/d3, not here.

I’ve fixed this in mbostock/d3#2755. It will be available in the next alpha release, 4.0.0-alpha.25.
