How to access svelte web app variables from the browser console?


I’m working with a Svelte 5 application that has already been deployed in production, and I don’t have access to its source code. I’d like to inspect or interact with some of its internal variables and functions from the browser developer console.

Here’s what I’ve tried so far:

Is there a reliable way (e.g., through DevTools, function references, or any hooks Svelte leaves in production builds) to access variables or functions from a deployed Svelte 5 app in the browser console?


Solution

  • There are no global variables except __svelte.v which contains version info.

    You can lift variables from a local scope by setting properties on window when execution is halted somewhere, but that is about it.
