vibium eval

Run JavaScript in the current page.

Synopsis

vibium eval "<javascript>"

Description

Executes <javascript> in the page context and prints the result to stdout. The script has full access to window, document, and any globals the page exposes.

This is the escape hatch for anything Vibium’s higher-level commands don’t cover — extracting computed values, dispatching custom events, querying the DOM with a custom selector, and so on. Reach for eval when the semantic commands aren’t enough; reach for the semantic commands first.

Examples

vibium eval "document.title"
vibium eval "document.querySelectorAll('article').length"
vibium eval "window.scrollTo(0, document.body.scrollHeight)"
