"Preserve log" in Chrome Console to see "Uncaught TypeError"? - google-chrome-devtools

When I uncheck "Preserve log" in the console settings, I don't see the error below. Why are they related?

When Preserve Log is enabled, the Console preserves messages until you explicitly clear it. When it's disabled, the Console clears messages on page loads.
So, it looks like there's some code that runs just before you navigate to a new page, and that code is throwing an error. So while the error technically does get displayed (for a split-second) in both scenarios, it's probably just getting erased before you can see it with your eyes when you have Preserve Log disabled.

VSCode debugger stdin\stdout not being shown

I'm writing a debugger for VSCode, is it possible to see what is going into and coming out of the debugger in VSC?
I thought stdout was going to be echoed to the Debug Console, but even with a simple application that writes a message and closes nothing appears.
Ideally I'd like to see everything including DAP messages? Is this available anywhere?

Remove anonymous debugger from Chrome Dev Tools

A while ago I was working on a webapp and for the purpose of debugging I've added a listener function directly in the console of Chrome Dev Tools and I've included a js debugger keyword in it to have a breakpoint there.
Now I can't get rid of that debugger and whenever I try inspecting the page, click on Select an element in the page to incspect it and I click anywhere on the page to take me to that node in the DOM structure I'm entering the breakpoint and I need to Continue script execution multiple times.
The debugged code looks like this:
I've tried triggering Never pause here option on each possible line, but it just opens a new VMxxxxx file. The breakpoint is not available in the Breakpoints list so I can't remove or uncheck it from there. Do you know how to get rid of it?
I was having the same issue, i found that one of my browser extentions was throwing the anonymous debugger. I solved the problem by disabling all my extentions, confirming the anonymous debugger issue went away and then reenabled one extention at a time.

Slow down chrome dev tool debugger reaction to my behavior

I am trying to debug in chrome dev tool. My form shows some weird validation error when I type something into the input field and then quickly click somewhere outside the field. I found the browser debugger is not able to catch my last click behavior and it becomes very difficult to debug where things go wrong. Is there a way to slow down the debugger's reaction?

CodeSandbox: Display codeline in console

How can you display the line of codes in the console in Codesandbox?
I was searching in the settings but couldn't find anything.
Assuming you're console.log()ing them, there's nothing else you need to do. Codesandbox will log whatever is inside a console.log() statement and show it to you in the console tab.
Your ad blocker may be the reason you don't see anything. Turn it off, or try running your sandbox in Chrome's Incognito mode (assuming you don't have an ad blocker enabled in Incognito mode.)

removed navigated to messages in chrome console

Is there a way to remove the navigated to messages from the chrome console?
I like to preserve logs to quickly see history but the navigated to messages add a lot of unneeded clutter.
You can go to Settings -> Preferences -> Console-> Uncheck the 'Preserve log upon navigation'.
The closest I can find is filtering messages by script.
And I don't see any methods for programmatically removing individual messages in the Console API.
