JavaScript: Is there a way to get Chrome to break on all errors?

Solution 1:

I got trouble to get it so I post pictures showing different options:

Chrome 92.0.4515.131 [11 August 2021]

Very very similar UI since at least Chrome 38.0.2125.111 [11 December 2014]

In tab Sources :

When button is activated, you can Pause On Caught Exceptions with the checkbox below: enter image description here

Previous versions

Chrome 32.0.1700.102 [03 feb 2014]

Chrome 27.0.1453.93 Stable

Debug options

Edit: The original link I answered with is now invalid.The newer URL would be https://developers.google.com/web/tools/chrome-devtools/javascript/add-breakpoints#exceptions as of 2016-11-11.

I realize this question has an answer, but it's no longer accurate. Use the link above ^

(link replaced by edited above) - you can now set it to break on all exceptions or just unhandled ones. (Note that you need to be in the Sources tab to see the button.)

Chrome's also added some other really useful breakpoint capabilities now, such as breaking on DOM changes or network events.

Normally I wouldn't re-answer a question, but I had the same question myself, and I found this now-wrong answer, so I figured I'd put this information in here for people who came along later in searching. :)

Solution 3:

This is now supported in Chrome by the "Pause on all exceptions" button.

To enable it:

Go to the "Sources" tab in Chrome Developer Tools
Click the "Pause" button at the bottom of the window to switch to "Pause on all exceptions mode".

Note that this button has multiple states. Keep clicking the button to switch between

"Pause on all exceptions" - the button is colored light blue
"Pause on uncaught exceptions", the button is colored purple.
"Dont pause on exceptions" - the button is colored gray
