An experimental data-flow analysis tool for JavaScript
FromJS shows you where each value in the DOM comes from.
For example, some data might have been loaded using fetch, some might have been stored in localStorage, and some might have been hard-coded in the JavaScript code.
Install from NPM:
npm install -g @fromjs/cli
Then run fromjs
from the command line. This will open a new
Chrome window.
Loading pages will be very slow and some sites will be broken.
