Run DOM-based Javascript from command line

Question

I have some Javascript that is interacting with the DOM from a website.

document.location.href="https://www.example.com";

It works well from Chrome console, but I would like to run that code from the command line. How can I do it? NodeJS gives "document is not defined" error.

What would `document` be in Node? And what DOM would you have when running a script in a command line environment? — VLAZ, Jan 11 '19 at 14:45

In order to use command line to inject Javascript code in a browser's DOM you actually need...a browser that runs Javascript code ad has a DOM.

You can go with something like Selenium or rely on a bridged library like https://github.com/prasmussen/chrome-cli

When you run the code from browser the DOM api is included, so your code excutes accordingly and finds the the location object with information about the current document your on. When you try to run it from command line using node.js the DOM api is not included which is why it gives you "document is not defined" error. Node.js is for excuting server side js code.
