How to programmatically turn a form into an API?
Any recommended libraries for programmatically filling in forms and accessing data behind them, preferably in Node?
There's an API for chrome and firefox that lets you remote-control the browser with code. I use this to run my unit tests so they really fill out forms as a user would and to save screenshots resized in various device resolutions.
