Description from store

Svelte Devtools is a Chrome extension for the Svelte javascript framework. It allows you to inspect the Svelte state and component hierarchies in the Chrome Developer Tools.

After installing you will see new tab in Chrome DevTools. This tab displays a tree of Svelte components, HTMLx blocks, and DOM elements that were rendered on the page. By selecting one of the nodes in the tree, you can inspect and edit its current state in the panel to the right.

doesn't work

Can stores be added. Unable to see the current state of a store. Was expecting to see store changes like what vue devtools offers

Simply does not work.

Unfortunately doesn't work for a while anymore in Chrome. I switched to use it in Firefox instead.

Doesn't seem to work. Not sure if InertiaJS is messing with this. Also tried it's Firefox variant and same thing.
Paul Hoover
This extension does not work. It immediately displays the following with no other information on how to resolve. "Not working? Did you..." "Use Svelte version 3.12.0 or above?" (yes, we're using 3.49.0) "Build with dev mode enabled?" (yes)

I couldn't make it work. I reloaded both svelte and the extension 3 times. If it does work you need to make it such it works out of the box. I don't want to jump through hoops of fire to make this work.

I tried to get this to run several times. Hard refresh, restart machine, incognito, remove and re-install. This does not work for me. Any ideas? Env = Chrome, Mac IOS 12.4, Svelte 3.22.3.

Doesn't work anymore on the latest version of Chrome, and when it did work - it wasn't very good.

It doesn't work and it seems to be abandoned.

Great extension that works as expected. The only thing I'm missing is better integration into Chrome's design language. Especially the small font-size is a major difference to the rest of the interface and potentially impacts a11y (other than being a subjective annoyance).

Does not detect Svelte when the application uses Svelte via Client-side component API (https://svelte.dev/docs#run-time-client-side-component-api).

Nice extension for debugging Svelte application

It looks like the vue dev tools and I think it better than nothing before.
Thomas Orlita
It would be super awesome if it also worked in Electron DevTools. Edit: It actually works in Electron, although not directly in DevTools: https://github.com/RedHatter/svelte-devtools/issues/37#issuecomment-781622702

Thank you for your efforts.

아주 좋습니다!
Joe Moses
In principle it works, it provides info on props and such, however the actual scope of functionality isn't too wide. The plugin struggles to detect Svelte when in embedded in another system, WP, running jQuery for example.
