Photon uses Svelte.js as the main JS framework for the UI. Photon uses Svelte 4 currently, but Svelte 5 was released and has a lot of benefits for the codebase. It's also a lot faster.

However, the paradigm for Svelte 5 is a lot different and almost the entirety of Photon might have to be rewritten.

Luckily, there's a migration tool that can do a lot of the work for me. However, I've still got to fix about 3,000 lines of code and 70 different files to work properly with Svelte 5. There's also gonna be a lot of hidden bugs I'll need to fix.

Because of this, I won't work on any new features for the next month or so, so that I can get this as done as fast as possible.

Generally you won't notice much other than slight behavior changes due to minor code structure changes, or maybe a bug or two.

Once I'm finished, I'll make another announcement and you might notice photon feeling a bit faster!

Once it's been confirmed stable I'll release docker images.

You can see my progress here

Photon has been fully localized and you can translate it to your native language now! (will not be released until v1.30)

You can help translate at the Weblate

If you need help, you can join Photon Translators Matrix room.

Ask for as many clarifications as you need.

Requirements

• Be fluent in the language you're translating to.
• No Google translate or other translation tools, as they are often inaccurate without context.

Basically, title. It started happening a few weeks ago. Sometimes it happens right away and freezes the whole DE, more often it happens after scrolling for a while. I know nothing about .js so let me know how I could help diagnose it.

I'm using phtn.app, Firefox 133, Wayland, Fedora 41.

Thanks!

Thank you for this beautiful app!

I have a minor issue I cannot seem to resolve - the upvote/downvote count vanishes immediately after reloading the page. I am using Librewolf (that is based on Firefox) and I have tried to disable uBlock Origin entirely but I can't get it to display correctly. Anyone else ran into this and found a solution? Thanks!

Image attached how it looks for me.

EDIT: Thank you for the responses, I'm not entirely sure what I did, but now it's working as intended. I'm very happy about that because Photon rocks!

Hey, I noticed a small visual bug where sort comments button doesn't update after choosing a different selection. The comments still sort just fine, it's just the button that doesn't update.

It seems like contrary to Lemmy-UI, Photon does not display the user supplied post language anywhere and also has no way to set the post language in the UI. Nor does it have the profile setting to set language visibility.

I generally think that this feature in Lemmy-ui causes more harm than good due to the various ways in which people accidentally deselect "undetermined" as a language option, or how community mods accidentally prevent people from posting due to strict language restrictions... and a bunch of other related bugs that caused me to abandon this feature.

But having no representation at all seems like a bad idea given so much of Lemmy uses that feature and it also seems like Photon does hide wrongly language tagged posts if people misconfigure their profile settings in Lemmy-ui?

I can't confirm the latter, but this report https://slrpnk.net/post/14769073 sounds a lot like that is what is happening.

I usually don't like orange/brown themes but I think this one's cozy. I decided to make it for the autumn season.

I used to ask these a lot during Photon's early development, but I decided to do one now.

Are there any major features you'd like added or issues you'd want fixed?

Hi,

I want to replace lemmy-ui with photon. How can I actually do this? Do I need to just install it using docker and reverse proxy to the port? Is there any docker compose method? Where can I set the environment variables?

TIA

Saw people on slrpnk.net were looking for a photon theme so I decided to make one. I'm not necessarily expecting this to be used at slrpnk.net, but I like the theme so I'll be using it. It has a nice light theme too.

It's pretty similar to a recent post for a "wintergreen" theme, this one is less saturated.

I'd like to learn about the community that uses Photon, so I've decided to make a survey! You can answer it if you like. In about a week I'll collect the responses and see if anything's interesting, and then I'll make a post showing any discoveries.

The survey just has a few questions about demographics, Lemmy usage, and knowledge of Photon's features.

this security issue can only be triggered by users fault, but it's up to the UI designer to prevent user mistakes causing potential credential leaks.

The login page

The login page is designed to be as simple as possible. Only 1 page, no extra steps. It'll validate whatever instance url you type in to ensure it's actually a Lemmy instance.

The problem

If the user mistypes the instance url to a typo squatting instance, your credentials were just sent straight to them. Bad. For example, I could setup an instance named lemmu.world, and if someone accidentally mistypes lemmy.world as that, I get their credentials for free.

Potential solutions

I'm not sure which one would be best as they all have problems.

• Require you to type the instance before you can start typing your credentials.
  • This complicates things and adds an extra step. This also wouldn't completely solve the problem.
• Add an auto complete list
  • This will work for popular instances as they'll know that they have the wrong url because it disappeared from the auto complete. However, I'd need to keep this list updated and id prefer photon to have minimal external ties. This also wouldn't work for small instances.
• Add typo checking
  • This has the same problem as above as I'd need to keep common misspellings updated and I want photon to have minimal external ties.

Any ideas? For now, this isn't a problem as long as you double check the instance you're logging in with, and there's no cases of this AFAIK.

TL;DR

Vercel has been a PITA for a few reasons I won't go into, and I eventually reached a usage limit that made the site unusuable. Cloudflare pages has no usage limits, so I have switched to that. Nothing different should be noticable, except that initial loads might be slightly faster.

if you don't like cloudflare

I understand lots of people dislike cloudflare, so if you want to get away from it, here are some publicly hosted instances:

| Instance | Location | Contact | | --------------------------------------------------------------------------------------- | ------------ | ------------------------------------------------------------------------------------- | | phtn.app (Official) | 🇺🇸 US West | photon@xylight.dev | | photon.thesanewriter.com | 🇺🇸 US East | thesanewriter@lemmy.thesanewriter.com | | p.darrennathanael.com | 🇮🇩 ID West | noc@darrennathanael.com | |zhenyapav@zhenyapav.com |admin@buckodr.ink | | phtn.ngn.tf | 🇹🇷 Turkey | services@ngn.tf | | lm.sudovanilla.org | 🇺🇸 US East | hello@sudovanilla.org (behind 1 version) |

You can also selfhost it if you'd like.

sh git clone https://github.com/Xyphyn/photon cd photon npm install && ADAPTER=node npm run build node ./build/index.js

Just a few moments ago learned about phtn.app, as I was using photon.lemmy.world. I'm trying to use it with KDE's Falkon web browser, my daily web browser in desktop, which is based on chromium (though as far as I know it's not cutting edge chromium).

photon.lemmy.world works just fine, but I don't get to pick spanish from the available languages - while in phtn.app is there (I used Firefox's web browser to check it and learn there's quite a few differences between phtn.app and photon.lemmy.world).

The thing is that phtn.app stucks on the loading screen (the circle spinner) with Falkon. Not sure if it's Falkon being funky or there's something that could be done on phtn.app. All I can see in the web inspector is the following:

!

Not wanting to pull Firefox/Chrome/whatever and all their dependencies just for this, so I'd like to know if this can be addressed in phtn.app's side.

I don't see how I can do that. There is no way to access the sidebar that's visible on desktop when I'm on mobile.

On phtn.app I can give all translators of Photon a badge, here's how it looks on @Blisterexe@lemmy.zip (the French translator!)

If you want this and you translated the app, just add a comment and I'll try to verify your contributions. Then I'll add it to phtn.app. I can add and remove this at any time, and this will only appear on phtn.app.

To get the badge, you must have

• Validly translated at least 30 strings of any language (other than English)
• Proof that you are the contributor on weblate (using the same username on both should be enough)

The readme talks about docker. I’m not a docker user. I did a git clone when I was on a decent connection. ATM I’m not on a decent connection. The releases page lacks file sizes. And MS Github conceals the size: curl -LI 'https://github.com/Xyphyn/photon/archive/refs/tags/v1.31.2-fix.1.tar.gz' | grep -i 'content-length' output: > content-length: 0

So instead of fetching the tarball of unknown size, I need to know how to build either the app or the tarball from the cloned repo. Is that documented anywhere?

There is also a light theme available, but I never use light themes ever so I have no idea if it looks okay. But it's there if you want to try it! If someone wants to help with the light theme feel welcome to. Thank you Photon devs for all the hard work you put into this beautiful interface!

Use the theme:

I've been messed around with random features in photon, and i tried something stupid today.

I was experimenting with an AI post summary feature, (just because i wanted an excuse to make a cool animation) but as I was using it, it actually ended up kind of useful.

If I were to implement this feature, it would only work like this:

• The user would have to opt-in manually.
• The user would need to specify what AI service they wish to use.
• The user would have to specify their own API key, if the service requires one.

In the end, I probably won't add this, since you can just copy/paste the content into an AI app. But it could also be slightly more convenient.

What do you think?

I just wanted to say thanks to all the translators of photon! Even if you only changed 1 word, translating this large app is not easy, especially because it's hard to find the context for certain actions.

With all of your help, Photon is now available in 13 languages!

English, Hebrew, Bulgarian, Estonian, Finnish, French, German, Japanese, Dutch, Polish, Chinese, and Portuguese!

If you want to help translate, you can do so at https://weblate.xylight.dev. You can translate as little or as much as you want!

Photon has a feature on links which gets data from Media Bias Fact Check to determine its media bias. However, I've seen controversy on lemmy.world's bot with this, and I'm not sure if this is the best place to get the data from.

Should I use a different dataset? like allsides'?

A lot of admins trying to host photon have been unable to after i switched from Node to Bun server. Bun is a newer server that is significantly faster, but it seems to have caused issues when hosting for weird reasons when people try to host it.

Starting from v1.31.2, I will publish node images as well as bun images, it's very simple to access:

Instead of ghcr.io/xyphyn/photon:tag, do ghcr.io/xyphyn/photon:tag-node

Photon, on mobile browser, seems to “snap” to the beginning of each post when scrolling. Is there a way to turn this feature off?

When I changed the default theme I saw someone say I should name the classic theme "AMOLED". Apparently, the theme was so dark to a lot of people that it appeared black! I guess my designer's eye and working on photon for over a year made me not notice this.

The classic theme uses a very dark gray for the main background, and an even darker gray for the sides. There was never any black, except in very very early versions of Photon.

So I'm looking for a new client, specifically mobile, that's FOSS, easy to use, allows for browsing communities on other instances easily (not just searching for instances, but actually viewing the list of instances, etc).

I'm a dev, so happy to put some legwork into it myself. So my question is - technically, is the UI tied to being run on an instance "directly", or could it be detached, electron- or atom-ified and put into an app?

I can do the work, but before starting I'd like to know :⁠-⁠)

EDIT: This is now integrated to Photon as the Neutral theme.

I did this a while ago, when theming was first introduced. I wanted a dark theme that wasn't black, and also not tinted.

json {"other":{"black":"#000000","white":"#ffffff"},"primary":{},"zinc":{"700":"#484e57","800":"#373b41","900":"#282a2e","925":"#202225","950":"#1d1f21"},"slate":{}}

TL;DR: nonstandard community and user links should work properly now, when people waste their time by doing [!community@instance.url](https://instance.url/c/community) instead of !community@instance.url

test

If you dislike the new default colors, just go to theme settings and select "photon classic"

This new update allows instance admins to set their own themes (via PUBLIC_THEME) and allows you to have multiple theme presets.

It's available on phtn.app right now, coming soon to a release

I like these colors, as it gives a bit more personality than neutral gray.

But what do you think? If I did make this the default dark theme, I would add presets to the theme page including a "classic" preset.

If you'd like to use this theme right now, here:

json {"other":{},"primary":{"100":"#f3f4f6"},"zinc":{"100":"#f3f4f6","300":"#d1d5db","400":"#9ca3af","500":"#6b7280","600":"#4b5563","700":"#374151","800":"#1f2937","900":"#111827","925":"#080C19","950":"#030712"},"slate":{}}

This will be a test post for markdown, as I'm switching to a faster markdown renderer that will allow me to do some cool stuff, like allow expanding images and running my code in markdown.

It might release with v1.31.2.

arguably a bigger update than v1.31, lots of backend changes for better speed

i've been using this command palette a lot because it makes doing everything so fast. let me know if there's any action or link you'd like added, since it's very easy to do.

What's Changed

• feat: add a command palette by @Xyphyn in https://github.com/Xyphyn/photon/pull/364

  • Press / or ctrl + p or right click the photon logo to bring up the command palette
  • Instantly start typing to find a link, or run an action

• design: Make compact mode even more compact

• misc: add infinite scroll to communities too

• code: rewrite how post feeds are handled, improving speed and cleanliness and allowing more opportunities for caching.

• misc: add support for upvoted/downvoted posts and uploaded media in the profile page

• strings: tweak some strings for better clarity

• Vertical postlink layout for mobile by @sevonj in https://github.com/Xyphyn/photon/pull/360

I'm working on adding a feature that will convert tags in the title to flairs, which you can add custom filters/rules to.

Hey, I've been working on a few changes to photon that make it a lot faster to open posts and return, and as a result of these changes I can also make infinite scroll work. If you go to this link, Vercel will have commented on the post with a preview link. Those are basically the beta links.

Let me know of any bugs and any changes you'd like!

Current roadmap

• [x] Make this not duplicate posts in memory
• [ ] Make this work on all posts
• [x] Use a virtual list for better render performance

all 0.19.4 features coming soon

One year ago, on June 24, 2023, I saw the migration to Lemmy. I wanted to make something like libreddit, so I decided to mess with Lemmy's API. Lemmy became something I wanted to use daily, so I got to work, and I made the first commit:

!

I started with something that reused components from another project of mine, Imagi. It looked awful and had no features. But, some people actually started using it, and I was motivated to continue this.

After about a month 0.0.1 was released, with very basic features.

One of the earliest Photon versions
