Debugging Typescript without proper tools, in a nutshell. The original file might have 72 lines, but the transpiled JS file it’s debugging is like 3 times that many
Honestly, you don’t want production to tell users what your exact errors are, and especially not what the source code looks like and where to find the problem exactly.
Production errors should mostly go “Well, this was on (y)our side, sorry about that” and nothing more.
If it’s in the minified front end code it’s already client side, of course you don’t show it to the user but they could find out if they wanted to. Server side errors are where you really have to watch out not to give out any details, but then logging them is also easier since it’s already on the server.
ugh… this reminds me of a compilation error I got that complained about an unknown character. Looked through the file, didnt notice anything, passed it around for other people to check and no one noticed anything until one person noticed that the quotes were being autocorrected to the straight quotes instead for some fucking reason. I didnt see it because 1) why would that even be a thing and 2) I am almost legally blind without my contacts.
Yep. I use a piece of software that lets me drag components onto a stage and will auto generate code in the back end. We can then add our own code to customize the components.
I ran into a super cryptic error message while working on a time sensitive project and I was ripping my hair out trying to figure out what the hell was wrong. Turns out someone had pasted some code in from an email and the custom code editor displays the straight quotes and angles quotes exactly the same but the back end code generation fortunately displays them differently. The program didn’t like the character set for the quotes used in Outlook but didn’t give me the proper line number, the error made zero sense, and looking at the code didn’t show that anything was wrong.
Learned the hard way that anything copied from a MS product gets pasted to a plain text editor first. I especially love how SharePoint sprinkles “zero with space” characters liberally throughout.
So I took a Marlin firmware for my 3d printer and just changed values like the bed size and added a BL Touch by uncommenting the specified line and the Visual studio errors out. I don’t get it
Instant PTSD. Only beaten by an error in, say, Line 84 in a file that has 72 lines only

That when the file isn’t minified, no shit it’s on line 1 there is only one line
Production errors at their finest

Ah you’re right, I’m thinking too much like a backend dev!
No, not all error have security implications
Not only that, but with JS you by definition have no code obfuscation. Minifying it just saves some bandwidth
Yeah, if one really wants obfuscation for JS, then it requires an extra build step. E.g. this: JavaScript-obfuscator
Enable sourcemaps

Long inline assembler.
Might as well just delete it all and start again.
I’ve seen errors on line 0 in the past
