That moment you realise Typescript is not called Typescript because it has types but because of the immense amount of typing you have to do to get anything done...

What do you call it when you type a script? A TypeScript. Then you spill coffee on it...
now it's a JavaScript.5 -
Completed Angular 2 course on codeschool, really liked improvements and simplicity of Angular over Angularjs. Decided to do quick start guide in official website. Oh my f**king god... I need to setup webpack, typescript linter, typings, polyfills etc angular2-cli is no better, crawling with errors... why... why can't one just start a project and work instead spending loads of timing configuring all of that... AND WHY WE CANT HAVE PROPER SUPPORT FOR LATEST FEATURES...
I don't even know what I am ranting about... I just wish to spend more time creating things than configuring for ages development environment.7 -
You hired me to be a JavaScript developer. Just because you have stock inMicrosoft is not a good reason to try stuffing Typescript down my throat. Maybe you should have hired a Typescript developer!6

I cannot take this shit seriously.

WHY DOES TYPESCRIPT EXIST OH MY FUCKING GOD WASN'T JAVASCRIPT ENOUGH
(just starting out on angular2 and i already hate it compared to jQuery)25 -
Hey, it's 2023.
If your component isn't written in TypeScript, I'm not using it :)
"TypeScript is overly complicated!!!" why, because it pointed out everything wrong in your JS code?
"TypeScript is not flexible!!!" why, because it makes you not rely on fragile "only possible in javascript" patterns?
"TypeScript isn't needed!!!" why, because you've never worked on a project with more than 100 lines of code where dependency management and clean code policies were implemented?
god just stop with the JavaScript purist BS, you aren't going to win this battle, and it's even worse because not only are you injuring everyone in the software community, you're injuring your own productivity and skillset
actually, you know what, fine. just use pure JS and HTML implementations. see you in 10 years when i'm retired and you are still running around in circles wondering why the world has left you behind24 -
You've got to be a masochist to be a javascript/typescript developer.
Each time I come back to the npm-related parts of my project, the application won't start because of some dependencies nonsense. And I know for sure I left the project working perfectly last time.
Every time... every fucking time! Just leave the project unattended for a week and be sure you'll find it dead next time.
I mean I as a developer don't really have to do ANYTHING for my code to break.
How can people love javascript is a mystery to me.15 -
It's interesting how much fun Javascript is, when you just ignore it and use Typescript instead. 😎2
-
Have a function that takes parameters and then performs a switch statement to determine what function to call next with those same parameters. One of those parameters is a Union type.
During CR, my reviewer said they’d like if instead of returning the function per case, I instead assigned a handler to the value of the function per case and then returned that handler at the end of the switch. Simple change, right? Only snafu, I’m casting one of the parameters on a per-case basis.
Somehow, through no fucking change of my own, TypeScript in its wisdom has decided that the type of that value by the time I call the next function is a fucking Intersection.
WHY THE FUCK DO YOU THINK IT’S AN INTERSECTION?! I’m fucking casting it per case! I’m ensuring it’s the right type for the next function called on a per case basis!
…. And that, my friends, is how I wasted a day with a stupid refactor that was ultimately just scrapped because no one could figure out how to make it work.
Goddamn fucking TypeScript. I3 -
Have I ever mentioned how much TypeScript compensates for JavaScript's Lack of being statically typed?
It's. So. Much. Better.8 -
if ( condition ) {
callback(data)
}
callback(error)
--is a lot different than--
if ( condition ) {
callback(data)
} else {
callback(error)
}
callbacks are not return statements 🤦♂️9 -
Why is Typescript such a snarky fuck?
a: number = 2;
tYpE Is TrIviAlLy InFeRReD fRoM NuMbeR lItERaL
Shut the fuck up you barely turing complete piece of digital refuse. Why does it bother you so much if I leave the fucking type on for clarity? This is almost as bad as my ex.5 -
I'm having such a blast writing code in TypeScript. Once you learn it you cannot go back to regular JavaScript.6
-
JavaScript is a rollercoaster. From "Golly hello world is easy and I can make webpages now", to "wtf '1'+1 is '11' kill me now", to "it's not be that bad if you know how to use it", to discovering typescript and it starts feeling like a real language.
... until you can't build the project because you have too many types so you blow the memory limit in node. I can up the limit, but I can't guarantee that we won't blow past this in the future. Browsing issues on the ts repo reveals that this has been a thing for years.
Sticking with the rollercoaster analogy I'm now at "Burn it all to the ground".5 -
Friend learning typescript: JavaScript is easy, you do exactly opposite of what you did in java. Typescript is a half baked mess.
-
Been waiting for vue 3 to support typescript, even after it released the support isn’t that good. I’ll just hope it got better in the future4
-
You have a JavaScript application. You have to keep up with stupid devs that don't know TypeScript because you don't have the time to let them study it and they get demotivated when they can't do stuff so fine, you keep it JS. You use JSDoc to write the documentation. You miss using TypeScript so you start doing some @typedef's. Oh your linter gets it and starts behaving as a substitute of TypeScript. You get excited and write more and more @typedef's! ... until they get so complicated that you start documenting *that*...3
-
Typescript seems like such overkill, but then you need to refactor your code and hit a bunch of issues in production. I don't think I'll ever go without typescript again. Fuck dynamic typing, it doesn't scale5
-
Yesterday, we searched in our IT comunity Angular jobs. One of first jobs had these tags: angular, react, typescript and dart. How can programmer decide, when even the company can't decide what to use...

I've written two different real time audio resampling algos (called on source and called on target) using linear interpolation, both in typescript, both work on first try and both perform great. I feel like the omniscient god of web audio processing.2

Why I hate typescript. Bored during quarantine so thought I rant a little more about this.
1. Compilation time, typescript increases project compilation time from 1 second to 3-4 seconds, which is basically triple or quadruple the time if you don't know math.
2. You write a minimum of 30% more code.
3. Many libraries are not written in TS by default, which means you end up having to manually install a fuckton of @types/(pckg name) manually which is incredibly shit.
4. Typescript is an absolute pain in the ass when using dynamic libraries. Plus when it works, it usually ends up finding maybe 1-2 errors in your code MAX, completely not worth it.
5.JSDoc is 100 times better. (Still don't use it though).
6. I actually enjoy loosely typed languages, having your compiler being smart enough to tell what the type of your input is is much better than it assuming you're a fucking retard so it forces you to manually type everything.
P.S if you hate loosely typed languages, kindly resort to Angular, C#, Java or whatever and leave JS alone, cunt.41 -
Hey dear HR people and Headhunters - learn to write proper Joboffers - when someone is a JavaScript developer and even writes JavaScript for 10 years for a living doesnt mean he can or wants to write strict typed TypeScript out of the box using an library ecosystem and NOT a framework already written with TypeScript (React vs Angular)
Write TypeScript developers in the job offers when you search them: TypeScript !== JavaScript.6 -

What do you guys think about TypeScript? Does it worth time to learn the syntax? Also what is the relation between Angular 2 and TypeScript?4
-
Damn bro Vue 3 sucks actually. It's just a big function now with arguments like "`this` can be sometimes confusing when TypeScript is used." - hell no, my component was a class and this was the fucking class. nothing was confusing about this.
It's all a clusterfuck of magic now, I don't see why writing `ref(5)` or `return { all of your shit }` after `setup() { complete business logic inclusive functions here }` is better.
I was so looking forward to all the improvments, but why do we need these 3 apis with actually no difference, tried to be explained by the same image of colorful blocks in every single fucking article?
what happened to methods? am i seriously supposed to return them from a function? that just feels wrong.22 -
Java errors: if something is underlined in red in the IDE then it is a real error for sure
TypeScript errors: if something is underlined in red in the IDE then 50% of the time it is some 🤡 sh*t2 -
Today i spent one hour and half trying to understand why my ajax request was returning "undefined" instead of a json object. It turns out i had just to restart ionic because of some bug in the ts transpiler.

typescript, I HATE you!
ME: Trying to extend Subject and override Subject.subscribe(PartialObserver<T>)
ME: export class MySubject<T> extends Subject<T> {
subscribe(obs?:PartialObserver<T>): Subscription {
return super.subscribe(obs);
}
}
ME: compile
TS: Compilation error! No such method to override!
ME: load the app -- ERROR
ME: recompile
TS: Compilation error! No such method to override!
ME: load the app -- works perfectly
:confusedjackie:
Make up your mind! So is that class compileable or not???
If not -- how the fuck does it work then???
If yes -- why the fuck do you yell in my face with all those errors???8 -
"I'm too freaking lazy to learn to write good JavaScript so I'm gonna build a top-language with types, and then a compiler so it transpiles TypeScript to JavaScript and runs my app on the interpreted language it was at first. I'm gonna save so much time" - 2017 people9
-
Thought I'd try out Asp.Net Core + React + Redux, at first I got shocked from the TypeScript shit I saw, but an hour later, I like what I'm seeing :P2
-
I fucking give up. Typescript is not meant for complex projects. It's meant for simple projects that are big. There's no way forwards, no matter how much I try to simplify my types I simply can not get the typescript server to stop lagging out the moment I do anything complex. It can't fucking do it, it just can't. And that sucks really, really hard.
I'm so tired of finding the ceiling on everything. I had a bad smell for typescript when it came out... and I never should have expected any more than this.14 -
One day after typescript , I ditch JavaScript on es5 totally and my college education on objective orient finally pays off ! !
I love functional programming but still insist that objective oriented is better for large project

my frontend colleagues always keep amazing me with their create way of writing code:
```
const input = "a";
const result = {
"a": () => console.warn("A was selected"),
"b": undefined,
"c": () => console.log("hello")
}[input || "c"]?.();

I was working on a thing at work which routes http requests from one endpoint and port to several local services.
I was halfway done when I noticed I just wrote a primitive reverse proxy.
Anyway, I'm calling it GRID, Gateway for REST Interface Distribution.
It's capable of dynamically attaching new routes and services and removing those during runtime via inbuilt typescript compilation service.
Each "runtime module" defines several routes which may have a middleware function (express.js style), which gets executed before forwarding the request to the local service.
I don't know why, but I'm kinda proud of this one; Feels like I made something actually useful for once.
Gonna maybe add a webUI with the monaco editor to write typescript modules without needing VSCode...
Also I may implement a load balancing system for scalability.
It comes with a cli too.
Gonna put it on github and post it here once I'm done with v1.19 -
Just came across a function with a typo (this is in TypeScript) - let's call the function slightlyComplicaedName - see the typo? t is missing. Wanted to refactor the function name to fix the typo. Next thing I know, the project doesn't compile anymore. There was already a function called slightlyComplicatedName in that file and it was doing something completely different.
I get that naming is hard, but using typos to differentiate between functions seems too much :)2 -

Dear TypeScript, could you not have chosen any other extensions rather than .TS? Apparently telesync have been using .TS for IDK may be decades. But all you could go with was .TS?
Now Windows Explorer keeps on thinking .TS is a telesync file thus it keeps on trying to load a thumbnail for the files whenever a folder with .TS files are opened.9 -
Hiii devRanters, I have a TypeScript question for you...
How do I dynamically import classes?
I have a class like this:
export default class Foo implements Bar {
...
....public getName(): string {
........return this.name;
....}
}
and then I have another file with this:
import(`./class-cmd/${file}`).then((command) => {
....winston.debug(command);
....winston.debug(command.getName());
});
the first command spits out something like this:
debug: default=class Foo {
....constructor() {
........this.name = "foo";
....}
....getName() {
........return this.name;
....}
}
and I would expect that the second command will work, however it throws this:
UnhandledPromiseRejectionWarning: TypeError: command.getName is not a function
Any idea what I might be doing wrong?17 -

Typescript: All of your javascript code is valid typescript
Installs Typescript
runs typescript
Typescript: line x in function y has an error
Checking the function for error and the code is fine
After wasting an hour comment out all the linez in function y
Run typescript
Typescript: you have an error on line x which is commented in function y
ERROR IN A COMMENTED LINE :(4 -
I mostly work in Java as a backend developer, but lately I started a frontend side project in Angular. Man, Typescript and SASS are awesome! Totally love it :)2
-
I implemented the equivalent of “?.” In typescript with a function callled safeRetrieve(descend into the field only if the object is not null).
We could not update typescript, so I just created this function and it made me used to use ‘keyof T’ as a parameter type… I still feel very satisfied after I use this approach with anything because it really feels like using typescript correctly!4 -
I knew AngularJS, just learnt Angular. Realized what typescript is and how amazing it is. I am a .Net guy so creating lambda functions in typescript made me excited lol. It's a little frustrating to write "imports" in every TS file though. Can now add ✔️Angular and ✔️typescript to my resume 😉. Starting with Vue.JS as soon as I am done playing with Angular.2

We are starting a new project where we decieded to use node.js with express.js. It is quite exciting because we have previoisly use node.js only a little and me and my colleagues are eager to learn something new. As I was doing some research I came upon TypeScript. Do you guys think that it is worth spending more time learning TypeScript and use it in upcoming project?6

I started making a library to get to know TypeScript. 4 days into the commits and I don't know if I made the best choice or the worst choice. I MEAN WHY CLASSES!!

A TypeScript boolean/undefined Flag variable kept fucking up
true == true didnt hold true

Reading OpenSource lib that write in TypeScript is a nightmare
WTF:
export function concatMap<T, I, R>(

resultSelector?: (outerValue: T, innerValue: I, outerIndex: number, innerIndex: number) => R
): OperatorFunction<T, I|R> {
return mergeMap(project, resultSelector, 1);

Typescript integration in Visual Studio SUCKS!! I waste so much time fucking trying to set up Angular 2 boilerplate that would take almost no time in VS Code or another editor because this bloated piece of garbage has to try and hack everything into MS build tasks and "Virtual Projects".

FUUUUCCCCCKKKKK!!1 -
I want to use Babel or Typescript for the first time. Because as I read it is the way to go, when compressing JavaScript and make it browser compatible. If that's false, please correct me.
There's a question I've got about this. Right now I am using a PHP router file dealing with requests and selecting the right .js file and compresses it. So I can write like modular JavaScript functions and include them when needed.
My question is, what do I have to change in my setup to switch to the mentioned technologies?11 -
Question: We are planning to transition our old ES5 codebase to modern ES6/ES7 and even typescript.
What would be the build tool you would recommend if we want to start supporting ES6/ES7 and even Typescript?
Webpack, Vite some other?
This is a vanilla Javascript Project with large codebase it's been built using custom build tools like UglifyJS and UglifyCSS and of after lots of begging it finally got the green light to move to a more modern build tool and start supporting a more standard JavaScript Features.
Mainly I want to move to TypeScript but transition would be slow so the build tool would need to support .ts and .js as well, that is traspile both the .ts and .js into one final production build.
What build tool would you recommend for that?8 -

Dear Microsoft, you are the one who created VS Code, Typescript. How could you possibly screw these things up? VS Code intellisense is terribly slow while working with Typescript but works so well when working with flutter/dart or any other programming languages. Shouldn't you be the one doing the best? Shouldn't you be doing a better job at something that you created? How could you mess it up??8

Typescript is like a condom that has sideways with passages to flow the stuff ! Which is basically a bloody condom with hole ! WTF 😑 .ts to .js !

Its sad to see the original creator of Node.js killing it for good.
Ryan Dahl had the guts to agree what he did wrong while building Node.js and some of the decisions which stays even today as irreversible. Hats off for him for bring everything to light and working again towards a solution using deno!
Which uses typescript and with a lot more optimized features, still in development tho.
Alot of people still loves node, including me, but do you guys really think it will last longer?

MFW I worked longer than 8 hours because of a weird bug that turned out to be caused by lack of typing in a third-party library. Was supposed to be a number but I was giving it a string 🤦♀️Need more sleep.

Throw a `parseInt` or warning for wrong type in there for me, fellow devs! Save consumers of your library a headache!! -

Anyone know how to go about unit testing an application that is made up of:
- Electron
- Node
- React
- Typescript
(React using Typescript of course).
Electron has its own framework (Spectron), people seem to use Mocha with Node, React has its own tools like React testing library (and testing UI components will probably end me) and Typescript seems to play best with Jest - but a special Typescript flavour of Jest called ts-jest is preferable because the only other option is having Babel and its Typescript support that doesn't type check.
I want to beg for the sweet release of death.4 -
I'll preface this by saying that TypeScript is a beautiful language.
But also UTTERLY INCOMPLETE.
Here's what I'm trying to do: give the compiler well-defined contextual type information for a decorator's argument (a lambda signature) and for the decorated class method, so the user would not have to toil and type every single argument.
But does that happen? No.
I'm honestly disappointed.

Fuck you eslint:
* Missing semicolon.eslintsemi
* Unnecessary semicolon.eslint@typescript-eslint/no-extra-semi4 -
When elements of an union are distinguished by a boolean, VSCode's Typescript plugin can only do type elimination if I branch by "== true" and not if I just branch by the boolean.
This is because Typescript treats booleans as an union of the constants "true" and "false", and compile-time elimination can only be done if I use syntax that makes sense with unions. Logical evaluation, for some reason, doesn't.
The fact that this issue can even appear is deeply concerning.1 -
How do you feel about using TypeScript with React? I appreciate the benefits, but, as every snippet of React code everywhere on the web is vanilla JS,I just don't want the cognitive overhead.
Yes, I know TS is JS, but, if I'm not going to use the features, why bother? I'd want to strongly type props, state, etc.
What's the status of TypeScript support in the React ecosystem (eg Router, MUI, etc.)?
I'm kinda hoping Reason will get some traction as the type inference is much better, but, will that happen? Or is that going to fizzle so it's a choice between TS and JS?
Appreciate any thoughts on this---including those from anyone who's in the same boat.
Looking for views on TS in React ecosystem---no need to sell me on TS in general.6 -

The adventurous world of javascript and typescript never ceases to amaze me.
I'm investigating some paths to take for migrating this legacy project which has incurred some technical debt. Because of... reasons... even the frontend Vue project needs to be built on a Windows system. No, you can take your hands down, even wsl or docker aren't alternatives here. It's a long story and ties in with said debt.
I'm keen on rebooting the entire frontend using a newer Vue cli and scaffold up all the essentials like eslint and typescript which is currently not used. This is gonna be sweet.
Except, typescript (BY Microsoft) doesn't play well on a Windows (BY Microsoft) filesystem because of a recent change to support - get this - wsl. I can't decide if it's hilariously ironic or genius.
This response about sums up my current mood. https://github.com/Microsoft/...
Of course, further digging in other repos like node only turns up issues closed due to it being on Windows' end.
So now my readme has a troubleshooting section describing how to make changes to your filesystem if you run into issues in Windows and I want to go home.6 -
It's probably no news that I love Typescript's versatile and powerful generics. Today I found what is probably the most brilliant use of these tools to solve a real problem. This package exports one generic type which takes one generic argument, reads it like a JSON schema and returns the Typescript type for it:

I didn't realize how mediocre autocompletion for python on vscode was until I started writing typescript on it. I think I'm gonna give PyCharm a try4
-
when some lib using Typescript they think that they can show in the top of the page function with the full fucking complex signature and that explain everything you need to know about what the function do and how to use it !
what about some simple basic signature, table of attribute name and meaning. and some good examples
like we have then on the old day ?? -
FUUUCK TYPESCRIPT
It can't handle this function: `(arg) => arg` without kicking around a bunch of generics.
https://stackoverflow.com/questions...
This is ridiculous. The generics system on Typescript is complete trash, the amount of things it's unable to handle are unbelievable, and I feel like I'm taking crazy pills when I'm supposed to just accept that they couldn't possibly have done better.
Seriously, if I was one of the developers and I saw an issue like this, I wouldn't defend it; I'd be embarrassed.7 -
You know the feeling when your mom come to visit and then start reorganize your stuff and complains about the way you choose to live ?
That how I feel when TypeScript come into my code and start reorganize my functions into Classes and bug me, all the time, about the types I must use to active there function

I recently went through a very detailed and well-explained Python-based project/lesson by Karpathy which is called micrograd. This is a tiny scalar-valued autograd engine and a neural net on top of it.
The project above is, as expected, built on Python. For learning purposes, I wanted to see how such a network may be implemented in TypeScript and came up with a 🤖 micrograd-ts - https://github.com/trekhleb/... repository (and also with a demo - https://trekhleb.dev/micrograd-ts/ of how the network may be trained).
Trying to build anything on your own very often gives you a much better understanding of a topic. So, this was a good exercise, especially taking into account that the whole code is just ~200 lines of TS code with no external dependencies.
The micrograd-ts repository might be useful for those who want to get a basic understanding of how neural networks work, using a TypeScript environment for experimentation.
With that being said, let me give you some more information about the project.
## Project structure
- [micrograd/](https://github.com/trekhleb/...) — this folder is the core/purpose of the repo
- [engine.ts](https://github.com/trekhleb/...) — the scalar `Value` class that supports basic math operations like `add`, `sub`, `div`, `mul`, `pow`, `exp`, `tanh` and has a `backward()` method that calculates a derivative of the expression, which is required for back-propagation flow.
- [nn.ts](https://github.com/trekhleb/...) — the `Neuron`, `Layer`, and `MLP` (multi-layer perceptron) classes that implement a neural network on top of the differentiable scalar `Values`.
- [demo/](https://github.com/trekhleb/...) - demo React application to experiment with the micrograd code
- [src/demos/](https://github.com/trekhleb/...) - several playgrounds where you can experiment with the `Neuron`, `Layer`, and `MLP` classes.
Demo (online)

Am i the only one who thinks TypeScript is not necessary, more some kind of overhead creation?
Whats your opinion about TS? Do you use it or just "good" old plain JavaScript?5 -
I dont know if i should learn typescript, i really like how it shows any error if you have done some mistake in the code in realtime. But it seems kinda hard and its not used that much at my office work. Should i start learning now or should i focus on strengthening my react skills for now? I work on react and javascript on daily basis.11
-
So just started to get stuck into my new book on TypeScript. My immediate feeling is TypeScript is amazing and makes JavaScript a zillion times better. What's others opinions?4
-
So typescript 4.5 beta is out .... holy moly what did those guys smoke? 🧐🤨🤪
They keep adding stuff on top, that nobody needs. But they don't fix the stuff that is broken (like emitting broken prefix-paths ...🤦)
Imho, they should focus on the overall development experience, make it easy an consistent to setup a proper multi-module project with linter, auto-formatter, folder structure, file naming.
And please fix this ugly #private fields - just ignore this mess of a spec and emit TS private fields as #private fields. That's the only logical way. Everything else is BS.8 -
Teamleader : just add TypeScript.
Me: Uhm okay?, someone has expirience with that?
Teamleader: No, just do it .
After 15h of trying adding TypeScript to the React / Redux App I ve to tell him that i couldnt do it.
So now I think that i am stupido as fucko..4 -
Does anyone have a good 'getting started documentation' for react redux with typescript. youtube videos and official documentation are mostly ES5.4
-
well folks, i've truly seen it all. an impressive an informative post on all there is to know about TypeScript, about time, since it's only 2023 and I've been waiting for this for so long!
...
"note: the syntax" 😂
remember that at the end of the day, this guy is employed, and i am not...
in all seriousness though, it's mind boggling to me these companies that market themselves as software or developer companies (or "professional" developers themselves) STILL aren't building their web apps using TypeScript
inb4 javascript maximalists / purists - come back after you've built and had to maintain multiple 10K LOC webapps and tell me that typescript didn't help you
🤡🌎🤡🌎🤡🌎🤡🌎🤡🌎

What's the point of using TypeScript if you type all of your code with `any` or worst part is you don't provide any types!?
P.S
If you're anti-typescript or any static linting tool, I know this will not prevent any runtime errors, but this is part of the testing/code quality. My teammates do not care for quality, and I'm tired of it.2 -
Why the fuck I see Typescript every fucking where. Either typescript is really something or this just huge-ass paid multi-channel marketing.8
-
Can you take this JavaScript file and make it TypeScript with tree shaking. Step one pass week to understand TypeScript and webpackShit compilers and try to importe it in a basic chrome windows ... What a mess10

I'm using typescript and run mocha acceptance tests. I was confused as to why my tests were failing on the Jenkins albeit they passed locally just fine.
I couldn't find the error. Just after making a pause, implementing something else, I realized what the problem was:
As I renamed a folder from `fixtures` to `tapes` my test run on the Jenkins suddenly claimed to not find the files in `fixtures`. Yet in my code base there was no occurrence of the string `fixtures` anymore and then it hit me like a brick wall:
I have old transpiled files in my outDir, the `dist` folder on the jenkins! Locally, I make sure to run `git clean -fd` once in a while, so I never was hit by it it locally. Yet my jenkins had really old files in the `dist` folder. And just running `rm dist/* && tsc` fixed the entire ordeal.
Well, JavaScript is so 2012 and typescript is the new shit, yet transpiling the code can leave to some quite strong headaches.1 -
typescript is shit.
I have never seen such a stupid bug in other languages.
https://stackblitz.com/edit/...
Apparently, there is no way to do type narrowing in a nested object without using enum12 -
The Typescript team issue trolls are just such asshats it's ridiculous. I've never once seen them even attempt to put themselves in the users shoes.2
-
So maybe stack overflow is better for this...but it's kind of ranty too so here goes.
Any react + typescript devs here? Cause I did something dumb. I ejected the project because I needed to build a custom express implementation...long story short, I can't run a webpack react dev server or use hot reload. Which is a PAIN! If I wanted to wait for a full TS and react static recompile after changing a css prop....I wouldn't be in the web game!!
Has anyone else had this and fixed it??1 -
Why TypeScript and Angular2 encourages you to link scripts directly from node_modules folder? What happens when you move the project to server(you know...the place that doesn't know about that folder). And how's the bundling gonna work?
5 -
TypeScript! Why you default compiler option "pretty" to false!? Why would anyone want this as false? This is such an amazing feature disabled out of the box! GNARF!
I USED TO GREP FOR ERROR TO GET ERROR HIGHLIGHTING!

I am looking for people looking for open source contribution. For the project.
I am making an Typescript based open source library for Basic Data Structures like Trees, Lists etc. Lodash for Data structures. So that I can be used in projects. I am making it in Typescript. If you are interested in learning and coding data structures, Typescript. Then hop on. Send a PR or Add Issues.3 -
I can not wait for the day till JavaScript can be thrown into the fiery pits of hell and we can just use wasm or even have the browser just support typescript natively.3

So I finally gave up trying to get TypeScript ES6 modules to work. Back to CommonJS it is, because fuck me I guess. I mean it *did* work... Until I also had to use a commonjs module at which point tsc basically tells you to fuck off with that2

The final hour of mental torture among many of finding a complex solution to an otherwise simple problem in a React/Typescript project:

Oi, typescript, why do you take 15 seconds to transpile my project!?
It's a waiting game for the unit test to even start :/4 -
10 years ago I remember adding a project reference to share code between some C# projects by right clicking and picking add reference. Took about 5 seconds. Here I am, 2021, and doing the same thing in Typescript is apparently a nightmare.
Every time I find something nice about nodejs, I find something else that pisses me off to no end.7 -
Today I had a dream, not sure if I can call it a nightmare:
I was doing ReactJS + TypeScript. but no matter how much I try, I can't seem to match the type of the variable/object. The IDE ( WebStorm ) kept showing RED marks under the variables & I kept trying, but no solution!
& Finally I woke up at 3 am :|1 -
How is building Typescript libraries for esm, cjs and dts with Rollup still breaking in 2023? I had a setup last year that worked perfectly fine, I copied it over to a new library and now tslib is being imported by relative path from node_modules? Why would that ever work?5
-
TypeScript types are fun. Problem is: the check is compile-time only.
I just wasted an hour not understanding that an integer passed from command line was actually getting transmitted as a string. The library, where that value landed as parameter, happily ignored the non-matching type and worked as if the value has not been set at all!
Dear library maintainer, please enforce your parameter types! Throw an error right into my face saying I shall not pass anything but an integer! Don't just continue to work to produce false output correctly. Thank you!
Dear TypeScript, I really want type checks on runtime.
Dear JavaScript: Why did you ever think loose types were a good idea? (And I say that as a PHP developer as well.)2 -
Today I escape from the clutches of the legacy iOS project ive been stuck in for about a year and a half.
Starting on a new team, totally different stack (TypeScript/Angular).
Its bad that what makes me happiest is that we have unit tests, something thats been missing from my life for so long now. I might actually get to do TDD now.
Life is good. -
The world would be better if the TypeScript guys knew what they could create with less complexity in any other language. Of course, if they are interested in learning. There are SPA applications out there that have more lines than Doom 3.7

About to write (and publish) my first npm package with TypeScript. It's basically just for json stream writing because the existing packages suck and/or don't do what I need
Guess my actual project I need this for will have to take a bit longer now -

My two main grudges against Typescript:
1) Union types can't be passed as arguments if there is a variant for every element of the union
2) No tuple polymorphism, i.e. [T, U] isn't assignable to [T]. This is not a mistake because the length of the arrays differs and therefore they may be interpreted in a different way, but IMO there should be a tuple type which is actually an array but length is unavailable and it supports polymorphism. This sounds stupid, but since function parameter lists work well with tuples it would actually enable a lot of functional tricks that are currently inaccessible.7 -
Scala is a better TypeScript. Feels so easy and natural to switch. Too bad it mainly targets Java devs. Scala.js is not nearly as popular as it should be.3

What do you guys recommend to read when starting Electron project with React and Typescript. I'm kinda stuck. :/
I've already make a simple Electron app with Js, but few people recommended me to try React, Redux and Typescript. But idk where to start.

Our company has the opportunity to start moving towards a more microservices architecture approach.
There is so much technical debt that needs to be paid back, this opportunity is a godsend!
Now, of course, the whole "programming language debate" comes into play at this point.
To provide some context, we've reached the point where we need to be able to scale, and at the same time where speed and performance are also important. I would argue that scale is of more importance at this stage.
Our "dev manager" (who is really only in that position since he's the oldest, like scribbling on a notepad and the sound of his own voice) wants to use Rust, as this is a peformant language. He wants to write the service once and forget about it. (Not sure that's how programming works, but anyhoo). He's also inclined to want to prematurely optimize solutions before they're even in production.
I want to use Typescript/NodeJS as I, along with most on the team are familiar with it, to the point that we use it on a daily basis in production. Now I'm not oblivious to the fact that Rust is superior to Typescript/NodeJS, but the latter does at least scale well. Also, our team is small - like 5 people small - so we're limited in that aspect as well.
I'm with Kent Beck on this one...
1. Make it work
2. Make it right
3. Make it fast
We're currently only at step 1, moving onto step 2 now!7 -
Okay so I’ve decided to learn React with TypeScript. I’m a backend dev and doing .net core. I know with React people use JSX. But it looks like typescript is becoming the norm. Also hear redux is outdated and the hot new thing is hooks. Lol. Don’t know man. Is this a good place to start? I’m gonna learn a little but of typescript, the. Jump to React. Not gonna do JSX.1

TypeScript has two levels of private values (at least in the beta):
private foo = false; // Cannot be accessed outside the object in TypeScript
#bar = false; // cannot be accessed outside the object in both TypeScript and JavaScript.2 -
Which syntax is "correct" TypeScript syntax ?. I prefer the first one. But what's about guidelines ?
Note for UpperCase variables: yes I know. We use that syntax to differentiate public and private variables. (Yes I know that doesn’t exist in JavaScript)

I have a readonly object property foo on a typescript class. When I create an instance bar by calling the constructor, bar.foo doesn't compare equal to this.foo as seen from within bar several async calls later. What could I have possibly fucked up?4

Does a non-awkward way exist to specify a child class as argument type in a parent class method in TypeScript when the classes are defined in different files?4
-
This is a TypeScript question, but that shouldn't matter.
Would you use dependency injection to get access to your controllers inside your router files, or would you just import them?2 -
Well, the time has finally come to tackle Typescript! So far it's not too rough-so I think I might put some effort into levelling up my redux skills too so I can put them together...maybe!1

Is programming a website/basic backend program in TypeScript with NodeJS actually a good idea? Or should you be programming it in C#, Rust, (not PHP), Golang, etc?
I personally feel like NodeJS has pretty amazing performance considering how much less code you would write compared to the other options. Although I feel something like Rust (haven't used it yet) would be more robust but more work.
Note: I only currently know JS, TS, C#, Go and obviously HTML, CSS9 -
SO TIRED of the typescript generics system. I get why you can't assign Thing<Foo> to Thing<any>, I do. But also, WHAT THE FUCK!? This is such a giant waste of time having to fix everything to pass around generics that I don't care about.
I've probably spent ~500 hours of my life wrestling this stupid ass type system.11 -
Sometimes I think that TypeScript is like a poor developer's Haskell. I thought "Isn't this supposed to support functional programming?" and searched for a way to do currying or partial application, and only found hackish solutions :/ Then again, maybe I don't know Haskell well enough to make a proper judgment.1

Just built out my first app using Cloudflare Workers, Typescript, and DurableObjects. Holy shit, this is nice stuff.
It's taken little to no time to build out:
* JSON API written in Typescript
* JWT verification against my OAuth backend (SAML support too)
* CI Automated Deployments including unit tests
* DurableObject support
* 3rd party HTTP calls + caching (built in to the framework!) to reduce network latency and hiccups.
* Cron-like tasks on each stored object so they can awaken the app on a schedule and update themselves as necessary
* Rapid deployment to new environments
The local testing with coordinated "miniflare" is dreamy too. -
Has anybody worked on ipfs implementing on client side?
Client side i mean ionic app.
any thoughts about running server side (node js) code in frontend (ionic - typescript) ? -
Loopback 4 really is pulling me out of the expressjs shithole... It really feels like I'm avoiding a lot of tedious work.
"B-b-bbut you have to use typescript and its a slower"
I've preferred typescript ever since angular 2 came out, and the 'slower' comment is invalidated by the fact that, when working on projects that are distributed between multiple devs, are marked by silent errors and serialization issues, and can change datasource types between customers, then the benefits of typescript and loopback's CLI far outweigh any potential slowdowns that may be caused. If you can find me an alternative that does this better, please let me know.1 -
Typescript Question
This is something that's been bugging me for a longer time now.
I did couple of React/typescript project (CRA) and it just keeps on happening and I have no idea why and even better - I have no idea how to query google with about problem.
From time to time I open a file that I KNOW was without any errors and suddenly BOOM - Parameter 'XYZ' implicitly has an 'any' type. And now I need to go and add explicit types everywhere it wants me to. TS Server restart doesnt help. Why does this keep happening? Any Typescript guru please?
3 -
Excuse my question I might be the one to blame, but on Typescript 3.7 JSON.stringify parses numbers as strings, while on 3.4 it was working without issues.
I'm no pro in web dev but I did use JSON.stringify lots of times and that's something strange here, not sure what the cause is, but when I parse number props again using parseInt(value.toString()) it works .-.2 -
TypeScript + Vue3 is such a bullshit combination.
No wonder they dragged Vue3's launch for years. Coz it's garbage.
Out of beta and in supposed-prod, yet half the time the complex objects disappear when passed around. Pinia is bullshit-ia.
Unrelated TS components fuck up and console logs a "Ayye New Error we didn't know existed, here go to Vue Issue Helper and tell us about it so we get to make Vue3 worse than before" ffs.
