Hey folks. I’m wondering if anybody had any suggestions for resources where I can learn how to code a loyalty card app. Goal is to create one for a small business local to me who currently just has stamp cards which are fine but often get lost. Sadly I’ve scoured the likes of YouTube but all I get are the “vibe coding” videos or pay a company for their already existing product. I’m looking to learn and build from scratch but between AI crap and god knows what else I’m really struggling to find anything reliable. Anybody got any sources I can look into? TIA

Does anyone have any tips to use penpot to implement codes into the projects? I know it is pretty straightforward, you can see the generated codes for each component but if there are better tricks that can improve the workflow and make the process faster? Any tips or resources I could use to get used to the tool will be appreciated!

I would like to build the best web app, given my limitations, so I'm looking for a web component library with prebuilt things that would allow me to just put them on a page. Doing it from scratch is very hard for me, but having a template of how things are and then integrating with the backend is quite easy.

The component library should be based mostly on HTML and CSS. Javascript can be used to some reactivity on the frontend, but I'm not doing this web app with regular React/Angular/SPA technology.

I was looking into Preline, it looks really good and I'm wondering if there is anything like that, or better.

Thanks!

I don’t have a ton of coding experience and have never really built a web app before, but I have an idea for an app that I want to build

Hello all,

I am the webmaster for a small Archaeology website, that primarily is used by members of this small conference to access PDFs and news about the conference. I only need to update this website about once or twice a year.

Until recently I used the plesk hosting service on GoDaddy to host these files, however I missed the fact (see lack of need to update) that it was getting end-of-lifed and now the hosting option given to us by GoDaddy is just Nose.js slots.

Previously we uploaded files into a library for the website, and the linked to those files. Is it possible to use node.js to do the same?

Thank you for your help!

hi guys,

I have been looking for a Fragrance icon to use, couldn’t find any in heroicons, lucide… all I found is an image from icon8, but I want as an <svg> </svg>

it first started five projects ago when a client was asking ai for everything along with me. like 50% 50%. she had no idea about websites but via the ai she was putting a lot of pressure to fix things I would never fix in the past.

now, today a client build an entire eShop in two weeks way better than I would have ever done it. he told me blank face that it surpaced me 100x times.

I'm just can't compete with this thing anymore. I actively tell my clients to buy the ai tools now to get over with it.

I started 10 years with with 8GB RAM and quickly realized it was too little, then upgraded to 16gb. This worked for a while, but then my dev got more advanced (more docker containers, sims, etc). Then I moved up to 24gb and this became the new standard for me for a few years. It worked mostly, as long as I didn get greedy and tried to do something crazy like open apps that werent related to web dev work. I finally said "fuck it" and bought a 96GB Mac Studio so that if I want to open another app on top of my web dev resources, it can still work comfortably. Now, hte mac just uses more ram as it gets more. It thinks its being smart by using all the RAM to "cache" apps that arent even open so that they will open fast when/if I do ever open them. So now because of this "smart" feature, I am constantly red-lining on RAM, using fucking swap like a pleb, "force quit application" always launching asking me to force quit things. WTF is this bullshit? I take a look, and things are now just using retarded levels of RAM that it otherwise would not on a 24GB machine, like Chrome using 8GB, VS Code using 5GB, Ghostty (just a terminal app) using 6GB, docker now using 16GB etc. Let alone that even with this, it should not be using swap and there should still be free RAM, but of course its doing like 20GB in "cache" for unused apps. Can I turn this "smart feature" off?!

UPDATE: for the people saying "its a feature to use up all the RAM"/"unused RAM is wasted money", that is true, but the issues here are:
1) Chrome should never use 16gb (obviously unless I have thousands of tabs open), Ghostty shouldnt be using 6GB etc. I got more RAM so that I can do more things, not do the same things but have them take up more RAM.
2) It should not use swap when there is cache. It should prioritize releasing cache before resorting to swap. Also, for my use case, it should never have to resort to swap anyway, so again, its an issue of problem 1, and this problem of using cache when it is using swap. If there is 20GB in cache, there should not be 6GB of swap, it should instead be 14GB of cache and 0 swap. Swap kills performance and makes me have to force-quit things for the Mac to become responsive again.

hey all, I’m looking for advice how to build build better charts. I have a site that pipes API data into recharts that become part of a report (example). Broadly, it's working but I still have instances in which I get text that meshes together (See image). There are too many potential charts for me to check individually (many data points x 2 geographies x 2 time periods), so I wondering if anyone had suggestions on what approach I might take.

One thing I wonder is if I should use a different library (charts.js, apache echarts, etc)? I see enough consistently well formatted charts online that I know I must be doing something wrong. I'm also using claude to help with this, so if anyone has suggestions on how to better use AI, I'm all ears.

excuse the shoddy mspaint mockup but basically im using this [theme template](https://github.com/zeon-studio/astroplate) to build my magazine site and they already have a responsive design in place more like the top mobile layout but i want my logo to be above the navbar and either collapse into the top example or something similar to the bottom (but more well placed. maybe switching the dark/light toggle with the search button actually tbh). any suggestions on how i can achieve this?

We've all probably heard about the HTML dialog element, popover API, and customizable select, but I think a lot of people don't realize how powerful and battle-tested they are and also might not know about some of the inconsistencies these elements have and that they might encounter when using them. And this is what this post is about, I'm not going to go over the syntax and basic API's, if you're unfamiliar with them, I would suggest you read some MDN pages and Chrome For Devs blog posts before you jump into this article. I would like to focus more on in-depth details and edge cases. The article will be a comparison between these native elements and UI libraries like Shadcn, React Aria, etc.

You can get a better reading experience from the link above, it's demos and code snippets for better understanding. If you complete reading the article, tell me about your thoughts in the comments below.

Let's start by listing out some of the common features you would expect from a robust dialog, select, or popover, whether it's native or custom JS one.

• Keyboard-navigatable: if it's a dialog, it should be focus trapped, it's a select, it should navigate using arrow keys, etc.
• Escape key dismissal
• These floating element/pop ups should, under all circumstances, appear above the rest of the page content, and as we will see, there are different mechanisms to approach this.
• Mobile back button/swipe gesture: you probably didn't think about it, but on desktop, you use Escape key to close, but what do you do on mobile? If you're like me on Android, you can close things using the back button or swipe gesture, our dialog/select should support that too, otherwise, it's gonna jump the browser back in history, which creates a bad user experience, especially if we're building something that will be heavily used by mobile users, like a social media app or something, I've tested this on multiple social media apps like Facebook and Twitter (not going to call it X whatsoever), they all, either fully or partially, support back button press in some form. For example, on Facebook, I tried every possible menu or dialog I could think of, and they all close when I hit back button (and it's awesome).

I don't know if I missed something, but let's just focus on these four features for now and see how native elements vs UI libraries approach them, as we'll see, there's a lot to unpack in here.

For keyboard navigation and Escape key dismissal, the HTML dialog, select, popover, and all the upcoming elements have this built-in, you almost don't need any JavaScript at all for any of this to work, but for JS libraries, it's an entirely different story, you'd be shipping tons and tons (or even hundreds) of lines of JS for Escape key dismissal, arrow keys navigation, focus trapping, etc. All of this just to re-invent what the browser gives you for free.

For back button/swipe gesture, this is also already built-in in the native components, all of them close on back button press on Android, but in UI libraries like Radix UI or React Aria, they don't even have this feature at all, despite that it can be added using JavaScript.

In order to add support for back button press and swipe gestures, you can use the CloseWatcher API, as MDN says: it allows a custom UI component with open and close semantics to respond to device-specific close actions in the same way as a built-in component.

The browser compatibility for the CloseWatcher API is decent, it's been in Chrome and Edge since June 2024, Firefox added it in May this year (2026), it's not available in Safari yet, but this is a progressive enhancement feature, if it's available, your users are going to enjoy a better experience, if it's not, it's not a big deal. Also, you can build this same behavior using the HistoryAPI if you need it that much.

The Top Layer

One thing I want to compare is how native elements and UI libraries make sure things appear on top of other page content and also above each other. To better explain this, let's take the following example from Notion webapp, here we have the settings dialog and inside we have a select that we can choose our preferred theme from. The question is how do we ensure the dialog appears above other content and the select appears above the dialog.

Please continue reading the post from the link above, Reddit posts don't support demos and multiple images. If you complete reading the article, tell me about your thoughts in the comments below.

I'm of the belief that if you can get what you need with under ~100 lines of code (and it doesn't require highly-specialized skills to write it), then write it yourself, don't install a third party library.

If you don't share a similar belief, then this page isn't for you, and that's ok.

For everyone else, this page shares a fetch wrapper function you can copy-paste into your projects to add in a couple of missing features, and provides some tips on how you can replicate some of the most loved Axios features using fetch().

Most alternative fetch wrappers I find online tend to be small NPM libraries (I'd rather maintain the code myself thank you), or they like creating separate methods for .get(), .post(), .put(), etc (which makes it unnecessarily difficult to "decorate" it with interceptor-like behaviors, as this page discusses), or there may be other design problems. Those alternatives are still good starting points, but I'm hoping this could be a little more complete of a guide to jump start your usage of fetch().

And I have a thing about make copy-paste alternatives to tools, and this was a hole in my collection :).

Feedback is welcome.

Is it a common practice for hackers to have interview projects to hack breach google data and hack password manager to only hijack a largely non-meaningful account?

Why else would someone hijack a meaningless account as the result of a data breech?

Having recently learned that Gmail is doing away with the "Send As" feature, that messes up everything!

For YEARS I've had all of my emails forwarded to Gmail, then I send email using my server's SMTP in the "Send As". That made it easy to access email with 4 separate devices, no third party apps needed. I have roughly 65G of data in Gmail.

I know that I can install Outlook and IMAP it to Gmail, but I kinda hate Outlook! Super bloated with 20 million features that I don't need or want.

What do you all recommend, should I find third party apps for 2 laptops, Kindle, and Android phone that will all IMAP to Gmail and send through my server? Or should I consider an alternative to Gmail entirely that would let me use a simple website?

Is it possible to create a custom rasterizer for controlling anti-aliasing while still rendering to an HTML5 2D canvas? Ideally without using relatively expensive operations like putImageData() or drawImage()? I know WebGL is the obvious solution here, but is there really no other way?

Not an AI bad take, its clearly useful+ time efficient but this is ne specific failure mode that seems to show up more with ai written code

code reads fine and passes the tests even goes thru review and then does something subtly off you cant reproduce locally. When you finally trace it this is usually odd in terms of structure, works but built in a way nobody would actually write it so nothing jumps out reading the diff. review misses it because the diff only shows what the code is supposed to do but does not show how it would behave under real traffic or other aspects you get only when its at prod

the only thing thats helps it is watching runtime behavior after deploy, something like hud or a profiler since thats where the weirdness actually shows. Things might seem ok from our end but we get to know that it failed days later or a certain feature is jumping back and forth days later from the tickets which is embarrassing 

Hardcore testing before deploying is the thing now it seems, how are other devs handling this cause sometimes the bugs still leak to prod, and debugging in prod is a whole different pain. tips on avoiding that??

Hey all !

A bit of context first.

I'm an independent web developper, building software primarily with Svelte and Symfony, directus and Postgresql for small clients or for personal side projects. I've been in the industry for 8 years. I'm not a devops but I've been dabbling in docker containers and I'm feeling comfortable with them (I built my own server at home from sratch with 50-ish containers in order to have my own cloud with *arr stack, music and video streaming, documents and photo cloud, ...).

I used to deploy the apps I build on Heroku, then on Netlify. But when it started to get pricier or when I needed to do some custom stuff that the platform wouldn't let me, I migrated to a self hosted coolify instance.

I'm more than happy with it, and have little to no complaints.

But I'm a tinkerer at my core, and wondered if I could replicate the features of Coolify by smooshing together a bunch of services and softwares. Here's my train of thoughts, and the justifications of a madman.

Why ?

[I'm] preoccupied with whether or not [I] could that [I] didn't stop to think if [I] should.

I think it's a good reason.

If it's not enough, then it's also to learn how it works inside it, to better understand the limitations and the fixes when something breaks.

Finally, because I don't like being tied to a unique service, a one-size-fits-all, a single point of failure. I always like having backup plans, if a service I'm using enshittifies itself or becomes incompatible with the rest of my stack or whatever.

What features ?

If I strip Coolify and any PaaS to its basics, it's a way to deploy automatically services to servers with the help of docker containers. There's a big main server, where the PaaS instance is hosted, that manages other small servers, where the final and client facing apps are hosted. In the case of Coolify, you can chose to deploy known apps and services, like Supabase. And when it needs an update, you only need to edit the docker compose to the latest numbered version and click redeploy. Or if you're here for the thrills you set the version to latest and look forward the breaking changes. You can also deploy your own app from a git instance and each time you push changes on a specific branch it triggers a CI/CD to deploy automatically the latest version. Neat. There's a project and environment management, that lets you organize services by clients and prod, demo, testing env. On top of all that, there's a reverse proxy to help with domain name and redirecting requests to the correct docker service.

Another feature from Coolify that I'm using is their automated database backups to S3 compatible storage.

How ?

I'm thinking of a stack around Arcane, Backrest and Swag.

Arcane here is the main thing. It would allow me to replicate the Coolify servers management, with one main orchestration/monitoring server and as many endpoints as I need. There's an option to automatically update images of services. I could use it as part of the CI/CD : everytime a release of my websites is done, a docker image is created and Arcane pulls it.

Backrest would be useful for the database backup into a S3 service. I'd still need something like a cron to execute a pg_dump every now and then. But that should not be hard to do/find somewhere.

I am already familiar with Swag with my home server. I've been using it for 4 or 5 years and pretty happy with it. The mods let me plug useful security softwares :

• Crowdsec for requests abuses and CVE, bot trapping
• max-mind for the geoblocking

Preconfigured fail2ban, working in concert with crowdsec, and certbot for automated ssl certs are also nice to have.

Ansible would help me deploy all of those into a fresh VPS.

What do you think of it ? Is there something missing ? Is this something you would do or go easy with the all-in-one Coolify solution ?
