WebDev

cross-posted from: https://lemm.ee/post/46067136

I'm designing a webapp that is supposed to be an AR environment on your phone, to be viewed with something like Google Cardboard, but I am having an issue that the segmentPointer object that is meant to appear when clicking on an object is not.

I've checked the geometry displays correctly in a sandbox, and when I change it to a 3d object rather than shapeGeometry it does display, but I cannot figure out why it is not displaying how I want it to.

The project is at https://voxelverse.jackgreenearth.org, and the code is quite long, but it is here to read in its totality below as it might need the whole context to discover the error. I've tried myself looking through the code, and I've tried searching the web and asking LLMs, but I couldn't figure it out, so please help me, fellow humans.

I can hear you all saying Semrush / Ahrefs. If you want a permanent and low-budget tool for this, I recommend Zutrix. It used to be free but they removed it now, unfortunately.

Website monitoring tools such as uptime monitoring are very important for application developers, Saas and e-commerce system experts and webmasters. I am currently using RobotAlp, an open source uptime monitor that you can use indefinitely. Apart from this, I am one of those who think that tools such as Status pages and keyword monitoring are also important.

Greetings, I have used WordPress infrastructure for both personal and professional websites for 15 years. In this area, I especially recommend using Rank Math as an SEO plugin. If you have any questions about development, we can answer them here.

What a funny intro! 😄

Deno is a modern JavaScript/TypeScript runtime built by the creator of Node.js, designed as a more secure and developer-friendly alternative. Unlike Node, Deno runs with strict permissions (no file, network, or environment access by default) and includes TypeScript support out of the box. It also natively supports modern web APIs and provides built-in utilities like testing and formatting, reducing the need for external dependencies. Plus, it’s modular, offering direct URL-based imports instead of relying on node_modules.

Hi everyone, I have an old gaming PC that I had repurposed to be my nextcloud and plex server using TrueNAS, but I recently found CasaOS and I would like to migrate my server to use this instead. What are some best practices that I should observe when installing a different OS into a server? My server is installed on an M.2 drive and I have two 1TB HDD setup in raid.

Whenever I launch a new web project I go to Google Search Console and Bing Webmaster Tools to flag that the new website exists. The idea is to start getting SEO seniority / attention as early as possible.

Is there any other tool I should be registering my website in, or are these the major two?

My Gitlab Pages site works well under domain.com but not under www.domain.com. The www subdomain leads to a 401 message: "You don't have permission to access the resource."

My DNS has a CNAME entry for www pointing to domain.com. When I asked the DNS provider what the problem might be they said "Please contact your hosting provider and provide us with the record needed to be set for www in the DNS zone. The changes should have worked already."

The reason I need this is that some old-school people visiting our website still type www. into the URL bar.

the code related to the video is a faily basic implementation using BabylonJS. it can be found here.

id like to see if i can get handpose-estimation to work well enough to be able to add to the BabylonJS render engine.

im working on something i hope will work like the 8thwall demo here. i couldnt find an open-source alternative to this so i thought id have a crack at it myself. my progress so far is as described here. i dont have much experience in creating games or graphics, so any guidance/help/advice is appriciated.

FAQ:

• why should i use it? - its a proof-of-concept app. for testing and demo purposes only.
• why create it? - it is a hobby project and i can be creative with the approach. its fun to work on.
• what is it? - maybe this article helps.

I just found about the rather experimental chaarts. It enhances the standard html and turns it into different charts. Complete with hover text and animations.

It seems to be pretty accessible. And if the user agent doesn't support the fancy css it degrades gracefully to the original

I've made a webpage for an event and on the ticket-selling platform they've also made a page. There's a lot of redundant information between the two. I'm finding it hard to decide if it's a good idea or not to deduplicate the information.

Personally, I would just have the information on the webpage and on the ticket-selling platform I would just sell tickets. The platform would have a link back to the webpage for people looking for more information.

It could be the opposite: the ticket platform could have all the info and just embed their iframe into a page on our website.

Anyway, the job is done for this time but I can't stop thinking about it :) Any thoughts?

I wrote a post detailing why I use meaning as the criterion for selecting my next web development project.

Hi,

I discovered this webpage
https://developer.mozilla.org/en-US/docs/Glossary/XMLHttpRequest

Where it say

The Fetch API is the modern replacement for XMLHttpRequest.

Without further explain on why so...

Did you (yourself) migrated from XHR to The Fetch API ? and is it better ? or do you know any (not bias) article about it ?

What about performances etc..

Thanks

When using dependencies such as NPM packages, Composer packages. Weather you use a CDN or host the packages on the web server, don't many packages out there require you to display the licenses of the package being used and show attributions?

How would one place this on their website? I even went to several websites to see how they do this and could not find a section and I am sure these website use packages that require the license to be listed and list the attributions.

I can find the licenses and attributions of packages used in many applications on desktop and mobile, usually in the apps "about" page.

Hello all!

I'm a beginner in web development. I'm building a simple small library application for learning purposes that has processes such as:

1. The landing page is an main index page with links to people page, books page, etc.
2. Suppose the user clicks "books", it will be redirected to a page with a list of all registered books, let's call it "books index".
3. The user can edit one of the books or click the "new" link. Both choices will redirect they to "edit-book" page, with a simple form that can be submitted.
4. After submission, the user is redirected to the "books index" to edit or add another book.

In summary:

[1: index] -> [2: books index] -> [3: edit book form] -> [4: books index]

In step 4, if the user clicks the "back button" in browser, it is redirected to the form page. If they edited 20 books, they will be redirected to the form page 20 times. It is rather confusing, so I want they to be redirected to the main index page if they are on the books index page.

It seems I cannot just remove things from browser history with Javascript.

Do you have any suggestion? I'm thinking about just adding a "back" button in the page which works differently from the browser button, but it would still add stuff in history, which could make things even more confusing.

Thank you very much.
