Headers is not defined

I instruct Zombie to visit a page which has the following code:

fetch('http://localhost:8000/', {
    body: body,
    method: 'post',
    headers: new Headers({ 'Content-Type': 'text/plain' })
}).then(function (res) {return true; });

Then I get an error that Headers is not defined, so the script within the simulated headless browser does not continue because it does not recognize Headers. Do I need to add some option to Zombie so it recognizes the entire standard JS Fetch API?

You’re running within the context of node, not the browser. You can polyfill the Headers class from the browser: https://www.npmjs.com/package/fetch-headers

You’re better off just using a vanilla object though…

I’d be more than happy to submit a PR that adds the polyfills.
