on react-on-hooks, how can i do a simple synchronous:
>addClass to trigger animation
>wait 500ms (this)
>set state
>addClass to trigger animation
???

Anyone know? >>75365256 I'll resort to hard-coding SQL soon.

>>75371794
You can use component state to check whether to load classes and trigger timeouts.
So set a state for when there's an animation loaded and change the state to something else in the timeout

What's the difference, filezise-wise, between exporting a default vs exporting a named object?

I'm making a component library and exporting them like so
//components/button/index.js
export const Button = () => {}

//components/index.js
export * from './button´;
export * from './card´;
export * from './checkbox´;
...


Can this be tree-shakeable? Does it matter if I export it as named functions instead of defaults?

Is the roadmap for backend development any good? I've already got past the javascript/html/css phase, am currently learning Java.

>>75372198
You haven't learned JS my dude.

>>75372177
B-but web components...
We use CSS-in-JS now.

i have no idea for my website anyways

>>75372288
You can use them in JS components, too. But the whole "styled" thing is retarded in my opinion, keep a separate sass file for each component instead.

>>75372241
>>75372265
lemme re-phrase this then

I am comfortable with Javascript; yes, there is a lot more I can learn, but I want to find out where to go next from here

>not mastering typescript
Oh so you're making it a goal to become irrelevant in the future

CSS is so fucking hard

>>75372779
>he doesn't know
>>75372759
Are you kidding?

CSS has a lot more concepts to learn than people realise. Most web devs I meet who think they mastered it don’t understand fundamental things like how collapsing margins or z-index actually works, or they don’t understand the difference between justify and align properly in flexbox or grid. Just keep chipping away at it

Question: Which is the better dev setup for a ts project?

grunt with ts watch task and nodemon watching ./dist

nodemon but using ts-node

ts-node-dev or node-dev or some combination

Seems like there are so many dev setups but which is the fastest to rebuild and work with?

>>75372951
Webpack?

>>75373075
How big is your ts project and what is it for?

Is it possible to alter the values of the options in a select-element from the browser?

I don't mean to switch between them but to actually change them DOM-wise like innerHTML.

>>75373121
You can target, add and remove them just like any other HTML element

Just use + operator

>>75374160
heresy, use `${variable} ${variable2} `

>>75374122
If you want other map-like features there are libraries for that which allow placing stuff on top, but otherwise just use absolute positioning. Might want to consider splitting the image up as well and lazy-load parts of it.

>>75374348
nice ty

>>75374503
>>75374520
Yeah, what is a cheap and ok domain for non company stuff, yet not a personal blog?

>>75374671
I use Scaleway ARM servers for my personal stuff since they're cheap and you get dedicated hardware so you can do whatever without anyone getting mad at you. Had several for a couple of years without any downtime.

I have an axios request that gets image links in a site, then I do a forEach for all links with a nested axios request to actually download the image files. It only downloads the last image, why does this happen?

If I print the image links in the forEach, they are all printed normally. Code in pic, you can ignore the html parsing and shit.

>>75374920
image_link and image_name aren't set in the foreach, are they declared further up?
forEach doesn't wait for async, so whats happening is it's getting to axios, then moving onto the next one. By the time the first axois call has finished, it's already gone through every element, so image_link and image_name are set only to the last one. Declare them within the forEach scope instead.

>>75375169
>image_link and image_name aren't set in the foreach
Sorry, I meant the variables aren't declared the foreach. Which means they're scoped outside of the forEach block, which is why it gets overridden before the axios call can complete.
You want to do:
```
const image_link = url_prefix+image;
const image_name = image.split('/')[3]
```

>>75375227
oh fuck lol how did i miss that, i'm used to writing python
thanks a lot anon

>>75375327
>Use namecheap for a domain, pricing is decent enough and they give you free WHOIS guard forever.
Yeah doing some research atm, and it looks like namecheap and porkbun are the best for domain because they come with free WHOIS protection. Porkbun is even cheaper. But still not sure about the hosting provider, any experiance with porkbun or namecheap as hosting providers?

>>75375870
one is tags for search engines, the other is description for search engines

>>75376080
2bh, I feel like it is one of those meme buzzwords sóy devs use to appear fancier that they really are. To me you'd sell yourself better if u told me that you serve separate files each for PC and mobile.

>>75375958
Yeah I'm hosting my sites there, it's nothing heavy, the performance is as advertised and I can saturate the line/cpu as much as I want.
I don't think France allows loli, but they have datacenters elsewhere as well (Netherlands I think) so look up their laws.
Found it on LEB a long time ago and there were talks about them when they were newer due to the ARM hardware setup. You can spin up and down machines and pay per minute so if you want to benchmark them it won't cost more than a few cents.

What do you do with onChange handlers for forms? Do you do them typed for several fields, a single handler for all fields or a different handler for each individual field?

>>75379504
The entire current node environment is a nightmare and deno is not going to improve it that much. So keep away from all those shits and keep .NET everywhere.

Should i start learning web dev for fun anons? Ive been wanting to make sites online like gambling sites and stuff. Dont want to do it as a job though. I get super bored when learning programmig languages. Should I still do it though? I know how to design in photoshop but thats it

This is fucking satanic

>>75379529
Honestly, if it's a bother but the form isn't touch anything besides a single host component, just use ```any```.

No I don't

>>75379417
Don't use .NET.
As for libs, I don't have any experience with Python, but if you're gonna use Node, try to minimize your dependencies. Node has some really nice built-in modules like net, http(s) and crypto, but most shit on npm is unstable and bloated (for real, not /g/'s idea of bloat).

Try studying CSS a bit to gain understanding of how it works. I'm guessing you're just plastering shit you found on stackoverflow onto your page

No. Any competent developer should be familiar with all areas of the stack, you don't need to be a master but at least have an idea of what's going on

>>75371455
I had a job interview for a position I’m not qualified for. Last night I fucked something up in a database and used one of my sites ftp to test some shitty code. Ended up leaving an index.php file that said “fuck you” and that’s what I left it at.
It was in my “portfolio” and they asked multiple questions about it. I forgot I left it that way. 5 people (including the CEO and the tech leads) in a huge company (pretty much responsible for most of the digital education here) saw me in a videochat talking about how I made a responsive site and shit and it was a blank page with “fuck you” written on it. I’m waiting for them to get back to me at the moment.

>>75381042
My uncleaned code is full of BAPspeak or ebonics and im afraid i one day forget to clean it

>>75381042
ahahaha rest in pieces friend. Maybe it impress them with your guts an bavado

>tfw companies web designers are actually just graphic designers

It’s so obvious. For one, they do not write any code at all. They create mockups. Two, the mockups do not work in the web. Like they sent me a mock-up that broke grid rules and had random margin added to the grid. All of the images are portrait. User is uploading portrait and landscape and sometimes nothing at all. They add background images that have to be absolutely positioned, but you can’t because it’s column specific and overlaps columns. The best is them randomly moving data on screen resize, like the name from the top to the bottom. I can push or pull within the same row, but I can’t move a row from a nest to the bottom of the page without media queries or jquery or having duplicate rows and show/hide depending on screen resize.

Since using an ORM for SQL in node is basically like mongoose, is there any inherent benefit to using something like sequelize over mongoose?

I know that mongo is a meme and relational dbs are better to learn, so would I just be limiting myself again if I use an ORM?

pls advise

>>75381202
ORMs are super useful most of the time, but if you don't know SQL you should get comfortable with that first so you have an idea what the ORM is doing when things aren't working properly.

>>75381042
Should have said it was a complex game you made where it displays fuck you unless you are geolocated within 50m of any locations of specific popular franchise where it would provide the next clue.

>>75381156
I had this conversation with my boss/creative director about how if he wants me to move the content into a completely different place on desktop and mobile I have to duplicate it and do a show hide which is undesirable from a page bloat perspective and other reasons, just blank stares

>>75381560
Just use Grid bro
https://developer.mozilla.org/en-US/docs/Web/CSS/grid

what's the best way to learn webdev and become good webdeveloper?

>>75381702
read the sticky

>>75381577
Grid doesn’t solve something being in the sidebar and now it’s squeezed between two random modules in the main content area, also those modules are user chosen in the cms so the layout makes no fucking sense

>>75371455
I'm using jQuery sparklines, and below is a code to make it, however, I have around 400 variables, and I don't think repeating is a good practice, how to solve it?

The code

$('#sparkline_var1_x').sparkline(var1, {
type: "bar",
barColor: '#fc3944',
tooltipFormat: '{{offset:offset}} {{value}}',
tooltipValueLookups: {
'offset': labels
}
});

</wbr>

>>75382199
Use an object and keys
var = {}
var[1] = 'whatever'

>>75382366
So, I'll end up something like this?
var = {}
var[1] = 'whatever'
var[2] = 'whatever'
.
.
.

var[400] = 'whatever'


And how's that will work within the code snippet? The variables aren't the main issue, I don't want to repeat that snippet 400 times.

>>75379417
.NET core, it is really nice these days.
Python might be easier and faster to develop in. Do you need/want types and how big is the project. The larger it is, the better it is to choose .NET.

>>75379417
Node, for sure at least in this context
It's just fun, and you can make it as minimal as you want, or load that puppy up with the words, beautiful spinners, color inputs, ascii, etc.

In general, is it normal to have to change code in many places when making any change to your frontend? It feels like everything is so interdependent that separating things into modules doesn't help with simplicity and just makes it so not everything has to be in one huge file.

Who do you think will get employed first once this all blows over?

What are the best languages for backend?

>>75386751
depends.

>>75371455
If the key of a react element is stored in _reactInternalFiber.key why shouldn't I just read it from there instead of passing it as yet another prop?

>>75387377
Then you’d be relying on an internal api which could change in name or semantics/usage internally.

>>75387390
That makes sense, thanks.

Anyone interested in doing free labor for me? I want to create a platform site but I don't have the time to make it myself because I'm still employed as a webdev.

I can offer you minimal requirements and corrections.

The frontend will be in React, I'd prefer the backend to be in Django, but I'm open to whatever since you'll be the one making it.

>>75387543
Are you looking for frontend stuff?

>>75388054
Yeah. I just want to do higher level stuff. I know html/css/js to a relatively high level , lead front end web dev for few years, SPA’s, programmatic animation, blah blah. Was thinking of diving into higher level performance profiling or whatever would add to my skills if I want to apply for a job at a faang or similar.

>not adding the required css to the head on your landing page to skip on a http call

shiggy

also, why aren't websites, especially JAMstack served over websockets? just deliver the minimal setup and have superior performance

>>75388131
I was thinking of implementing lazy loaded components in svelte using Interaction observer because it sounded fun.

There's also some fun to be had by benchmarking your js and trying to optimize it.
Or you could go and read the v8 blog, they have some interesting stuff when not posting WASM:
https://v8.dev/blog/cost-of-javascript-2019

I'm just a guy doing web stuff on my own so I'm not quite sure what would benefit you the most desu.

>>75388791
I do a lot of bespoke ui/interactive stuff so haven’t really dived into wasm yet as it has no access to the dom (last I checked). Definitely something to keep an eye on though, maybe for complex layout calculation and sending result back to js to apply.

Still haven’t dived into svelte yet, was waiting for it to mature slightly. Is the dev experience polished? Like create-react-app level of getting stuck in and easy to deploy etc.

>>75388931
>>75389079
On a more serious note, minified/uglified JS is indeed impossible to make sense of

>>75389071
You could, for example, combine left/up: 50% with transform: translate to make something sit in the middle.
Or maybe display: flex with align-items: center and justify-content: center if applicable

>>75389170
Yeah it don't work that way I wish it did but shits out of whacking whack, I use justify-content center and that shit goes fucking left corner of viewport lmao fucking kill me

>>75389071
Define centered on a screen, is the box the only thing there or is it floating above other content

>>75389191
bruh just think of this, flex is easy mode css, if u dont make it work ur a brainlet

lrn2 css in element inspector to see inmediate results, u can save from there too if u working locally, now go for it, champ

>>75372776
>WASM
>existed for multiple years
>nobody still uses it
>most companies deprecating the idea

who ever created css needs to suffer eternally in fucking hell

>>75389391
Of course it will at some point. People want a faster backend for processing and calculation even if it never touches the dom. The only thing standing in the way is apple trying to kill web apps so they can keep apps in their 30% cut walled gardens on mobile. But this can only go on so long while google embraces the web apps.

>>75389425
More and more people are abandoning static languages, so why should they suddenly adopt WASM? Answer: they won't. JS is the future

>>75389439
Is it just you moaning about css for the past 2 days?

should you use VSCode or Sublime text, or something else for programming?

>>75390795
If you’re starting out I recommend sublime text for getting up to speed. It won’t distract you. VS code when you find your feet. I still use both for different purpose. Sublime text is the best for quickly editing files, especially very large ones, it’s just much more responsive.

guess using pseudo-element with my word as content to just cover my specific word is the only choice i've got, right?

>>75392792
No, you can implement it two ways. The first way is to use an interval on the frontend. Your frontend requests the messages in your chatroom every few seconds or so. You simply GET /chatroom/:room_id to retrieve the latest messages for your room and show them on the frontend. It's a bit primitive but gets the job done

The second way is to use websockets, in which case the server stores each room and the client connections for that room. When a message is received to a room, it pushes the message to all connected clients in that room. You can have multiple rooms with their own client connections, you don't need multiple instances for this

I am doing it lads
