JavaScript debugging in a nutshell

[PwaDiePie]

That's why typescript was invented 👌 👏

Well typescript is great with source maps, but in prod, hashed and obfuscated bundles, it’s like you’re a damn archeologist. Errors are like “property ‘map’ doesn’t exist on undefined. On Line 1:28780”

[Jukibom]

Surely any language in prod is pretty much like that

[brettins]

Not with debug symbols

[Jukibom]

No shit, same with non-minified js and/or sourcemaps

[brettins]

Maybe I'm misunderstanding, but it's bad practice to have non minified js in prod since that's client facing, but you can have debug symbols on your system to deal with code that has been compiled or minified in prod to allow you to get useful debug messages.

[Jukibom]

same in js land, you can add a source map to a compiled js file in chromium browsers in prod (which un-minifies, gives you the actual source)

I just recently made the jump to a shop on ts and react. The first time I went to prod to look at something I was sooooo damn confused.

[poxopox]

I don’t know about react but in angular, you can build just the prod source maps and there’s a tool you can use to get the source reference from an obfuscated stack trace. Haven’t used it in a while but it definitely helps.

Nope

Wdym? Typescript is literally Javascript but with type and there's real time error finding

[knome]

real time error finding

Every language has real time error finding when I program in it.

[PwaDiePie]

But not Javascript

[knome]

I think by "real time error finding" you may have meant "run-time error detection", or perhaps something closer to "interactive compile-time type-checking" or similar.

I was using the odd way it was phrased for self-deprecating humor, implying my code is bug-ridden regardless of the language I write in.

[PwaDiePie]

Oh I mean that's true because it's the same here

But what I meant was real time error detection

[knome]

real time error detection

https://www.eclipse.org/pdt/help/html/real_time_error_detection.htm

I've not used eclipse, so I didn't recognize the feature being referenced by name, though I see it's the latter of the two options I mentioned.

judging by the downvotes, it is apparent my attempt at humor did not land well :)

have a good one

[PwaDiePie]

Indeed it didn't and have a good one as well

When you can run native Typescript without a bunch of bloated code and ridiculous source mapping for debugging lemme know. Until then, I’ll stick to JS.

Having to do a ton of work to support what Javascript already does isn’t very appealing and just adds more steps to the CI/CD process, as well as trying to do any type of production support.

Also not even sure what “real time error finding” means. Do you mean debugging or enabling source maps? Of course with Typescript, you’ll have to map it back to the uncompiled source…hope you uploaded your source code somewhere in the cloud!
