- Knockoutjs debugging extension.
+ Adds an additional sidebar in the element pane of chrome dev tools with knockout context and relevant data for the selected element. Very useful if you have large/nested views.

You can view the content of any observable in the viewmodel in the '$root_toJS' variable.

Currently this breaks dev tools when running, has to disable it to get the debugger to start running again.

Unfortunately this doesn't work at all!

Works only in old versions of chromium-based browsers. I set up Opera 76 and debug there

chrome >v.92 workaround: Create a live expression in your console and take this: if (window.last$0 !== $0) { window.last$0 = $0; console.log('\n\n-------------- Knockout $data ------------\n', 'element:', $0, '\n data:', ko.toJS(ko.dataFor($0)),'\n context:', ko.contextFor($0));}

No data are showing on the Knockout out debugger screen as of today.

Can't write Knockout without it! WARNING: Make sure you don't enable tracing, it will cause the entire page to lag and then freeze on bigger projects. It's also recommended to turn off serialisation to reduce memory usage (by clicking on the extension's icon in the top-right of chrome and then clicking options).

Vivek Pandey 2020-01-28

Fantastic

Stephane Berube 2020-01-15

broken in 2020

Ron McCranie 2019-03-01

Doesn't work. Either that, or it's extremely confusing to get it to work. Looking for something easy.

Mohammed Farhadur Rahman 2019-01-23

I've been using this extension for a couple years now. I think it's essential for Magento front end development where KO is used.

Attila Tóth 2018-11-26

I used to rely on it, but it's not working for me with 3.5.0 RC2.

Daniel Clarke 2018-06-14

Good for checking on knockout contexts in dev tools, but my god, it becomes slow as treacle even on the smallest of views, will remove from chrome now. would recommend if in a real bind, would not recommend for day to day use.

Ben Ashley - JLUK 2018-05-14

Does what it says but limited filtering options for suggestions vs issues.

Pippa 2018-04-20

cant live without this

Krunal Parmar 2018-03-16

Not able to see values in Knockout Context panel. Can only see observables only No way to dig into obesrvable.

MrOnosa 2018-02-09

I'm going to parrot what Andy Hawkins said two years ago: !!! If you experience slowness when debugging in the elements tab !!! Go to extensions and then options and turn off the first checkbox for serialization. This will fix the issue.

Steve Ottenad 2018-02-08

Its a valuable tool, but only because there are none else like it. There is a memory leak or something that routinely crashes my tab.

Andrew Hood 2018-01-25

Invaluable tool for doing coding with KOjs. Thanks a bundle.

Paul Hoke 2017-09-14

Great tool. I don't know how I could do my job without it.

David R. Noel 2017-08-17

Necessary for development in any Knockout environment.

MobiusHorizons 2017-08-17

Apparently this no longer functions in recent versions of chrome. I was unable to get it to show up.

Chris Hawkes 2017-07-10

Albert Puig 2017-04-26

Está muy bien para proyectos simples. Con iframes no funciona.

Jean-Sebastien Binette 2017-04-01

So far so good. THANK YOU!!

Michael Pavlak 2017-01-17

Must have tool when developing a Knockout application. I have worked on several applications of decent size and never ran into any performance issues noted by others. I imagine that if you have performance issues, your models are probably insane. :)

Dave Lee 2017-01-12

Very good,thanks

Dirk Reuschling 2017-01-10

It's good to see whats in the model, but it breaks the Chrome process with a "Ah Snap" message when I check the properties of a specific html element.

Karmjit Singh 2017-01-04

Awesome, must have for each knockout developer

Puneet Bhasin 2016-12-14

This is invaluable tool for knockout. A must have!
