Thinking about making my own lemmy client, but I could use some feedback

it should have good moderation implementation and have its markdown synced with lemmy ( like spoilers etc. ).

It should be easy to block, report.

I like the idea of the offline support. Could be cool if you are able to "download" a post for offline reading or just reading through its comments.
<= could be linked with the "favorite" functionality of lemmy.

Thanks for adding another app to the diversity of lemmy.

My goal is to store everything offline for a period of time. Likely, it will be more complicated than this, but let’s say for now everything you see will be automatically cached offline for 30 days. Instead of a number of days, I will probably set a max size for the offline cache and drop the oldest data in the cache as new data comes in.

The only issue here is I’m not sure how easy it will be to cache images offline. They will take up more storage, and I’m not as familiar with image caching mechanisms for apps.

Do you know if Lemmy tends to have good alt text for images? That would be easier to cache offline instead of images.

Maybe after the initial version, I can add the ability to pin a post to your cache so it doesn’t get cleaned up automatically.

in reply to moseschrute

There is no implementation for alt text yet on lemmy, how would it handle post purges? / removals?
in reply to Rooki

I assume you mean when my app caches a post, but that post is deleted from Lemmy. That’s a good question. Off the top of my head, I would say as soon as I know a post is deleted, I would likely want to purge it from the cache.

I guess it’s a question of whether I should respect the API saying the post is deleted or act like a temporary archive. I’m open to either. From a technical perspective, it would be simpler to act as an archive.

As far as the type of cache I use, I may use a LRU cache, which will effectively prevent something from being deleted every time you view it. So even if something was cached a long time ago, if you pull up that post again, it will reset the timer.

in reply to moseschrute

I would prefer if its deleted by creator or mod/admin it should be deleted as soon as possible. To reduce bad/harmful usage of that feature.
But i cant stop you do otherwise ;D
in reply to Rooki

I agree with that. It’s similar to if someone loads the post in their browser. If the site isn’t actively polling the API to check if the content is deleted, they will continue to see it until they reload the page. The difference is the cache lives longer. I can probably have it poll the API when they reopen a cached article, and if it’s been deleted, purge it from the cache. The result is they may see it flicker as it’s purged quickly, and if they’re offline I wouldn’t be able to poll the API.
in reply to moseschrute

You can use the hash for image caching.

in reply to asudox

Got it. As you can see, I am myself very new to Lemmy and still learning their API. I still need to think through this more since even caching hashes will consume much more data than caching the text content of posts and replies.

Most likely I’ll want to give control to the user of what they want to cache. Either text or text + images.

in reply to moseschrute

Looks like lemmy api does not give the hash of the image, that's unfortunate.

You'd need to use the link field instead.

in reply to moseschrute

Update on this matter:

I made a feature request for including an image hash with the image_details table but it seems like they will be adding a blurhash field instead, which is unique enough for a temporary cache that will at most probably cache ~100 images at best.

Oh and yeah, you probably should get ready to support blurhash in your client. It both acts as a small hash and a way to show blurry "previews" of the image.

in reply to asudox

I was just looking at image_details but for the height and width of the image. I see this exists in the TypeScript client schema, but I’m not seeing it populated for any posts. Any idea when this is actually populated?

Knowing the height and width of images before loading them would reduce layout shift.

in reply to moseschrute

Seems like the image_details table was added in Lemmy v0.19.6. if you are testing it with your current instance (LW), it's still using Lemmy v0.19.3. That's why.

in reply to Rooki

I’m not sure what percentage of Lemmy users moderate, but I would likely prioritize features that benefit the most users. Moderation might come a little later, but my goal is to allow you to do everything through my app eventually, including moderation.
in reply to moseschrute

Sadly then admins and mods will not use it until it has those features as otherwise it would be pain in the *ss to use it and swap around.
This entry was edited (2 months ago)
in reply to Rooki

Yeah, that's primarily the reason why I'm still using Jerboa.
in reply to Rooki

Again, I plan to add moderation features. But I am one person with a full-time job. I need to prioritize the features that will please the most users. Prioritizing everything initially could mean lots of bugs in the app, and I would lose users quickly due to a crappy app. I would rather build features slower but correctly.

That being said, if most Lemmy users moderate, then that would make this more of a core feature. But again, I want to also build an app that appeals to incoming Reddit users, and those people won’t be moderators. I’m hoping this will be a tool that can help grow Lemmy.

in reply to moseschrute

Could you make a 'save post as draft' feature? I think that would make it stand out right now. I'm not sure if any other apps have this yet.
in reply to technomad

That would actually be easier than the offline upvote feature. The issue with offline interactions is if you upvote in one app, but downvote on another, who wins?

Offline posts wouldn’t suffer from this problem. That’s my very roundabout way of saying, this shouldn’t be that hard to do.

in reply to moseschrute

That would actually be easier than the offline upvote feature. The issue with offline interactions is if you upvote in one app, but downvote on another, who wins?


Whichever interaction is sent 'last' when connected. No, the user would not have any control over this in the example situation,but to be honest it is a pretty minor issue with no real solution. The same thing could happen in an arbitrary order if you clicked different options on two different browsers at approximately the same point in time because web calls are not instantaneous.

in reply to snooggums

Respectfully, I don’t think it’s that simple. I think it’s one of those problems that appears deceptively simple, but when you dive into it, it becomes a big headache. One big difference between truly offline first and arbitrary web requests is an offline first app imo should let you close and reopen the app without dropping those pending interactions. When you marry this with cross platform, you need a robust database solution on both native and web, which makes the stack more complicated. I will consider making aspects of the app offline first, but I have decided not to make fully offline first a core feature.
in reply to moseschrute

Requiring the app to be opened to sync would be annoying for someone who only uses the one app and just wants it to update in the background. Unless the two apps communicate with each other to sort out a priority, there isn't a way to determine which one counts from the app side.
in reply to snooggums

Apple is pretty stingy about how often tasks can run in the background. Offline first quickly spirals with complexity that isn’t immediately obvious imo. That’s why I don’t want to make fully local first as a core feature.
in reply to technomad

Connect saves drafts transparently as you move around the app.
in reply to smeg

Awesome, I'll give both of these another go then. Thanks
in reply to moseschrute

Settings synchronization between every device would be a big plus.

I’m really happy with Voyager on iOS, but an app for my linux computer would be welcome as I’m kind of struggling with how Lemmy appears in Firefix.

in reply to Dariusmiles2123

I kinda want to avoid building a backend for this if I can. That would also mean your app wouldn’t depend on any infrastructure that I own, preventing any centralization around my backend. And it would mean a very low cost for me to maintain this app.

One way to solve sync could be to have a QR code you scan to sync settings. But it might only sync when you scan it and not continually. I can also look into any Apple or Android APIs that might make this possible, but that would leave out web, and I really want feature parity between all platforms.

But this would fall under a nice-to-have feature that I would likely not prioritize. I really want to nail down the core functionality first.

in reply to moseschrute

I guess it’s true that it would way more infrastructure.

Still the QR code idea would be great 👍

Thanks in advance for your work

in reply to Dariusmiles2123

Lemmy UI is only one option, although it is the default for most instances. There are a lot of different web clients, some of which will preserve settings:

Voyager

Tesseract

Quiblr

Photon

Mlmym ("old-lemmy")

Alexandrite

in reply to gedaliyah

I’m very new to Lemmy and I need to read through their API. Whatever settings they allow me to save, I’m happy to lean on their API. I just want to avoid writing my own backend.
in reply to gedaliyah

I'm surprised so few people have mentioned Thunder, which I use. Is there something keeping it from being more popular?
in reply to kionay

Thunder is a solid app! I don't believe that it has a display for large screens like PCs, but it is cross-platform in Android and iOS.
in reply to moseschrute

It sounds really nice. Something to decide early on is whether to make it open source. Many people who use Lemmy specifically (more so than Reddit I am saying) will only use an app that is open source.
in reply to OpenStars

It will be open source. I have no plans to profit from this. My goal is to keep my costs really low - as near $0 as possible - by not running any backend for the app. Everything will be local. I do hope to build a nice app with a lot of users to add to my portfolio, but other than that I mostly just want to see Lemmy succeed long term.
in reply to moseschrute

in reply to OpenStars

I need to set some constraints for the project. IMO, going multi-protocol will be too much work. I would rather do one protocol really well than try and satisfy multiple. I also primarily use Lemmy, and a Lemmy-based app is something I myself would actually use. Doing a different protocol would require me to put myself in the headspace of users that I’m not as familiar with. Much of building an app is sympathizing with your user base not just technical.

But I plan on making the app open source, and that means it can always be forked and adapted to a different protocol later. And I’m happy to draw inspiration from other protocols.

I appreciate the idea! I think a multi-protocol app would be great, but again I think for this project and my limited time, doing one thing well would yield a better result.

in reply to moseschrute

in reply to OpenStars

That makes sense. I appreciate the history lesson. You’re right, my account is very new, and I’m new to Lemmy. Maybe the protocols you mentioned are more compatible than I realize. I would imagine that if Lemmy.world migrates, what they migrate to will be more similar to Lemmy than something like AT Protocol. So it might be okay to run with Lemmy for now and then adapt later depending on where most users wind up.

I still would like to keep the project’s scope smaller, but if there was a mass migration from Lemmy, I would absolutely reconsider. Let me also read up on the similarity of the protocols. If interoperability is easy to do, I’ll consider interoperability from day one.

in reply to moseschrute

in reply to OpenStars

Interesting. If you have any talks or articles, I would love to learn more. Without knowing anything about PieFed vs Lemmy, I will say I do think it’s important with any product to nail down its core functionality first. Trying to please everyone can degrade the overall quality of the product. Is it possible Lemmy is focusing on core functionality first? Like it’s interesting that PieFed includes some features but lacks more basic features.

Swapping out API calls shouldn’t be too difficult, but if the schema of the data is very different, it could get difficult. If PieFed was a superset of Lemmy in the sense that it returned the same schema with additional information, then it becomes easier. AT Protocol is a good example of having a completely different schema, making it more difficult to implement interoperability - I know people are working on interoperability, so I’m not saying it’s impossible.

I know nothing about PieFed, so that may sound ignorant on my part, but I will do more research.

in reply to moseschrute

I have nothing to do with PieFed, beyond liking it and so I joined the flagship instance as a regular user, which gives me only small insight into the day-to-day usage experience:-).

That said, the main developer has given several talks - e.g. this one and see
also Rimu's YouTube channel.

in reply to moseschrute

FYI, its not true the 80 percent of users are on lemmy.world see here (total number of active users) and here (number of lemmy.world active users).

Also piefed as far as i know does not really support multireddits , you can't define a feed of groups of communities as a user. piefed topics are configured by admins or the developers .

in reply to OpenStars

requires sending ~25-fold less data per post


what are you referring to with this? AP traffic?

do you have some more information about this?

at least the image resizing topic has recently been fixed in lemmy, thumbnails sizes are limited (at the time of thumbnail creation) in the latest release. I'd have to look closer at the other stuff, the api part is unlikely to have changed and will affect all frontends, but js part should differ depending on the front end. some instances already use other frontends by default and there is also a replacement for lemmy-ui being worked on (lemmy-ui-leptos), but I don't know how they compare. either.

it should be taken into account though how much of this is cacheable as well, as it will then typically only affect the first load for the static files.

I can totally understand the issues in general though, I've been living with a 64kbps uplink for several years in the past.

in reply to Nothing4You

in reply to OpenStars

Not just open source. It needs to have a sustainable community of developers. I’m not interested in a project that dies when the one maintainer has other priorities (been there with another lemmy app) Open source just means anyone can fork it and carry on, but if nobody does, it still dies.

in reply to Docus

In that case, it would have been better if OP had offered the type of functionality that they wanted (e.g. cross-platform support, better responsiveness to tablet screens, etc.) to Voyager, as in like make a fork of Voyager and add in the new desired features. Elsewhere in this thread OP acknowledges that this would have been preferable... yet they are going to do their own thing regardless. Which isn't nothing imho, even if something else might have been more ideal.
in reply to moseschrute

Voyager is already cross platform for iOS, Android and web. It is also open source: github.com/aeharding/voyager
in reply to MrMakabar

Wow, I totally missed that. However, it does feel like the web was tacked on as an afterthought. It feels like navigation hasn’t been optimized for larger screens (see screenshot below). A sidebar would be much more usable on larger screens than this stretched bottom tab bar.

That being said, it would probably be easier for me to contribute to Voyager than to build my own app. But I also kinda want to build my own app, lol. But I might also consider contributing to voyager if they are interested in optimizing their interface for larger screens.

in reply to moseschrute

If you don't like how voyager does some things, fork it to add your own ideas. It's faster than starting from scratch.
in reply to Blue_Morpho

True. The thing is, my day job dictates the tech stack I use. There are specific technologies I want to learn in my free time, and those technologies happen to align well with this app, in my opinion. Forking is probably the smarter move… but I think I’m going to do it my way.

in reply to fmstrat

Tamagui + One (built on React and React Native), tanstack for querying and list virtualization, flash list for native list virtualization, maybe Zustand, Dayjs. It will be 100% TypeScript. I will likely use no Server Side Rendering with React. I would like it to be possible to host the site via GitHub pages for free so the project can easily be forked. Beyond that I’m still deciding.
This entry was edited (2 months ago)
in reply to moseschrute

Good luck then, with that stack you'll likely be working alone as contributors typically drive forwards Flutter these days. But it sounds like you're doing this to learn anyway, which is great.

Personally I use Thunder and added the two column view for tablet, had considered PRing a web and/or desktop compilation to see how it looks, but realized I never used it. I don't even have a standard web UI up ony server all the time.

in reply to fmstrat

in reply to moseschrute

React Native is big because ot was first. Stats I've seen show new apps leaning towards Flutter since Dart compiles native, unlike RN. RNs native parts are written in Java, and personally I've found Flutter to solve all the issues I had with RN.

For instance, large image galleries were simple in Flutter, and required all kinds of memory management in RN.

That being said, I still like RN a lot, so don't take this as me bashing on it.

in reply to fmstrat

I do think React could learn a lot from Flutter. I don’t think React is going anywhere, but I wouldn’t mind if they borrowed some of the good parts from Flutter. But also, I understand that RN vs Flutter have very different approaches to how they render under the hood.
in reply to Monsoon

That’s a great question! As far as I can tell, Voyager is optimized for smaller screens, and larger screens are supported but not as well optimized. My app would have first-class support for large and small screen sizes. Alternatively, I may consider contributing to Voyager.
in reply to moseschrute

Honestly, I'd say pick an OS and stick with it. Cross platform is tricky and it's not that good.
in reply to ByteMe

I’m a seasoned developer with experience in both React on the web and React Native. I’m looking for an excuse to dive into Tamagui, which is designed the tackle cross platform. So I’m excited to tackle this challenge.

It will be responsive, supporting phone, tablet, and computer screen sizes along with everything in between.


isnt this already what browsers do? why reinvent the wheel here

in reply to originalucifer

Sorry, I don’t mean this to sound rude, but websites don’t magically become responsive. It takes a lot of work. And that becomes even more complicated when you want to share large amounts of code between web and native.

I’m not reinventing the wheel. I’m using the best libraries—imo— to build a responsive cross-platform app.

in reply to moseschrute

My favorite app for the fediverse is firefox on both mobile and laptop.. but I use an instance that 'just works', mbin-based
in reply to DarkThoughts

yeah I forget how terrible the lemmy site is being able to access its content on a site that doesnt look like some forgot the css.
in reply to moseschrute

Why not take an existing client like Voyager, and add the features that you are missing?

This is exactly what I am doing for "easier onboarding". I am working on a fork of Voyager, learning my way through React Native and ionic, and adding support for Fediverser to it.

in reply to rglullis

That’s a great point! I kinda want to write my own client, but I haven’t ruled out contributing to Voyager. It’s very possible I totally fail, learn from my mistakes, and bring what I’ve learned to an existing app like Voyager.

in reply to moseschrute

You are right. I am still looking at anything related to the Fediverse as work and not as a hobby, and I shouldn't be expecting other people to share the exact same vision and ambitions.
in reply to rglullis

in reply to rglullis

it feels like FOSS alternatives would be 20 years in the future if put worked together on 2-3 alternatives instead of 20-30 disparate projects.


Honestly having 20-30 separate projects is awesome if merging in the creative bits from each were merged into the more popular ones more often. Sometimes there is a foundational difference that makes that a lot harder than plug and play, but to be honest not developing with being modular in mind is one of the biggest issues with any kind of development.

in reply to snooggums

if merging in the creative bits from each were merged into the more popular ones more often.


Yeah, the pity is that most of the times this simply doesn't happen, and everyone wants to reinvent their own special flavor of wheel.

in reply to moseschrute

I used to love slide for reddit because I felt it did offline the best even tho it couldn't up vote or comment
in reply to secret300

That makes sense since upvoting and commenting seem the hardest to me. I think anything that interacts with existing content in the API will be more difficult to do offline than creating new content (e.g. creating a post offline).
This entry was edited (2 months ago)
in reply to moseschrute

Offline mode will need a robust handling of replies and comments for content that has been deleted or removed if you want the user to be aware, especially if they have multiple comments on deleted posts when they reconnect.
in reply to snooggums

Yes! Exactly, I don’t think offline first should be a high-priority feature. I will spend too much time trying to get it perfect at the cost of other features.
in reply to moseschrute

Awesome! Have a look at the Lemmy Apps Directory if you are interested in comparing the features of existing apps. You should especially see the web apps section, which has some brilliant solutions to cross-platform and cross-device functionality.
in reply to moseschrute

This directory also lists the dev for each app, and most of them are great at being responsive and helpful. Of course sometimes people get busy, but the development community has been great here.
in reply to moseschrute

Great idea! Just here to offer support. I don't think voyager existing matters much, diversity is the name of the game for the fediverse.

Feature wise, I'd love to see something that embedded youtube videos and similar media with the url given but I'm not sure of the feasibility. Making something forward thinking that can eventually be integrated with other activity pub services would be a good idea but I'm certain that brings up the workload as well.

Keep us updated and make a sub when you have a name!

in reply to Grimy

I have experience doing YouTube embeds. It’s not hard. It’s just a question of all the different types of media embeds I also choose to support.
in reply to Grimy

Fwiw, the Tesseract front-end for Lemmy (e.g. on dubvee.org), Mbin (needs an extra button press iirc), and PieFed all do native YouTube embeds, for posts using that as their URL.
in reply to moseschrute

I use Voyager on android but the web client or "old reddit" style on larger screens. You could also look at redreader which is an android reddit client that could be adapted to Lemmy. IDK if there's an iOS version.
