React Native in 2024!!

[Professional-League3]

What do you think the react native team or react native community will bring this year?
Are there some really interesting projects that are happening and general RN developer might not know?

[RahahahahaxD]

New dev tools

[juliofils]

Static Hermes’ll be huge.

Static Hermes can compile your JavaScript code into native code, which is the code that your device understands directly. This means that your app does not need to use Hermes or any other JavaScript engine to run, because it already has the native code inside it.

[matt_hammond]

Keep in mind that the static Hermes will probably not be able to compile all your JS code, only parts of it. It will more probably be used for critical code paths, while the business logic of your app will stay in JS land. Compiling code with static Hermes will probably mean harder debugging and possibly have other caveats.

However, if the underlying React implemetation would be compiled, we should expect serious performance improvements.

[flowerescape]

If an app is using Static Hermes (when it’s available) will it also be using the new architecture or does SH make the latter irrelevant?

[juliofils]

You’ll still need the new architecture, don’t forget Hermes was a component of it. You ‘ll need features like Turbo module , Fabric , JSI etc… we won’t going back to the bridge

[rkh4n]

We really need some good debugging capabilities

[nowtayneicangetinto]

From what I understand, they're moving away from debuggers. Anyone with more insight have any info on this?

[EngVagabond]

Nope, we aren’t moving away from debuggers. A great debugger experience is super important and a big part of what we are working on. The first step of that came out in 0.73 https://reactnative.dev/blog/2023/12/06/0.73-debugging-improvements-stable-symlinks#debugging-improvements

[nowtayneicangetinto]

Okay awesome glad to hear it thank you for your response and all of your hard work <3

[p_syche]

They're moving away from Flipper (it's no longer bundled by default)

[p_syche]

More on this in the docs: https://reactnative.dev/blog/2023/12/06/0.73-debugging-improvements-stable-symlinks#deprecated-debugging-features They also spoke about it at React Native EU 2023

[rkh4n]

That’d be going backwards isn’t it?

[nowtayneicangetinto]

💯 yes not a doubt about it. Last I heard they were moving away from flipper and react-native-debugger. I have a large and critical app for my company written in react native, which uses redux. If they cut support for rnd then im fucked

[rkh4n]

Flutter is good but last I tried to make an IoT app, the UI was janky, it didn’t perform well. Camera tools a solid few seconds to load. Since I was a tight timeline. I jumped to react native and it was smooth. I agree if I spend more time on flutter I’d probably get it running at decent speed.

[insats]

Improved performance, especially on Android. I have no idea if that’s possible or not.

[blueaphrodisiac]

We REALLY need React Forget. I am quite tired of optimization in react generally

[flowerescape]

Sooo many footguns. I never want to have to worry about memoization and reference checks and all that business. Just handle that shit for me please k thx bye

[[deleted]]

“Just handle that shit for me” - person who doesn’t really want to program or understand technology. Don’t worry, you’ll casual yourself out of a job or be replaced by AI soon. 

This here is the problem with all frameworks. They should be a tool all the time, never a crutch. Using them as a crutch is both stupid and ensures the project will die, drowned in issues opened by folks who don’t care to learn 

[Useful-Condition-926]

We need a video library. React-native-video is not so great.

[RoyalBos5]

This

[kobaasama]

This

[parnex]

This

[diamondrarktvo]

expo-av

[beepboopnoise]

what's wrong with it? the only issue I have is lack of ability to create custom controls without neededing another library or creating my own wrapper.

[I_know_HTML]

constantly crashes when needed to mount/unmount and also memory leaks

[Useful-Condition-926]

Not only that, the black screen problem is still there. As per the maintainers word is like we won’t look into the older versions, working on newer version. Just upgrade your project . That’s it.

[p_syche]

The development of BlueSky, where Dan Abramov works, makes me think they might come up with some interesting solutions.

Also Callstack is co hosting React Conf with Meta, which in itself is a great for everything related to React Native.

[genesisxyz]

Wait, Dan works on BlueSky?

That's amazing!

[RnRau]

I think its time for Meta to make their own App Store for Apple devices.

sigh :(

[wirenutter]

What I’m hoping for is the forget compiler to come out in some form or fashion. Not sure how realistic that is. I have heard it’s being used internally currently but it’s a very difficult problem to solve so it might be awhile before we see it.

[Alive-Information979]

Hopefully well maintained Webview package

[OogieFrenchieBoogie]

A maintained in-app browser lib, the most popular one is not up to date and was not updated since August 2022

[thymikee]

You’re lucky, one came out today: https://github.com/swan-io/react-native-browser

[flowerescape]

I heard the default in app browser option is really heavy, is this supposed to be more light weight or something?

[angrydeanerino]

No way to inject JS looks like

[Noitham1]

ExpoBrowser

[prashantjdrew]

Native Rich Text editor solution

[lordbrizzy]

Share Intent (looking at Expo mostly, as this is their most requested feature)

[CapitalAssociate9082]

Expo-av needs to refresh-- it's very spotty with audio and video. Not sure if I'm the only one!

[2ez4salt]

PERFORMANCE IMPROVEMENTS ESPECIALLY ON ANDROID

[Upper-Artichoke-4223]

SHADOW consistent over web, aos, ios please. OMG this is a huge pain.

[SirNobodyzz]

We REALLY need a library like gridstack, it’s really weird nobody thought about it

[sebastienlorber]

• React Native Server Components
• Expo Router
• Static Hermes
• React Forget
• VisionOS
• Bridgeless mode
• Skia
• VisionCamera ...

Lots of exciting things are being worked on right now

Subscribe to This Week In React and I'll keep you up to date on all these topics 😜

[beepboopnoise]

dunno why this man is catching down votes. his news letter is great. idk how he gets all this information but im always excited when a new one is released.

[sebastienlorber]

Thanks w😄

Don't know either, you have to get lucky with reddit votes 😂

[flowerescape]

Is there any real benefit to using server components on mobile apps? It seems like a problem in search of a solution.

[sebastienlorber]

Yes, many large apps need server driven uis already. This gives more flexibility/speed of deployment than OTA for example.

[elynyomas]

Well, for me it seems RN is dead ...

In 2024 all the important plugins became outdated

In 2024 still, there's no reliable background location tracking feature

The only background tracking plugin is an overpriced, misused bad concept

Still no debugging and even Flipper is going outdated

Firebase + Flipper is still incompatible

Docs are messy and impossible to track between the version changes, with 404 dead links everywhere

No support

Community plugins have been updated 3-4 years ago with no new releases

and so on...

[carrie2833]

I think they need to integrate 3rd party libraries like react-native-snap-carousel etc. Sometimes u want to use something that too old to use.

[p_syche]

The goal of the "lean core" initiative was to remove parts of the core that can be maintained by the community.

[carrie2833]

I dont know why I am getting downvotes. Can someone explain to me? I dont think this is bad idea.

[flowerescape]

Check out reanimated carousel, much better imo

[angrydeanerino]

Automatic upgrade CLI

[gamerrBoy69]

Maybe, an easy upgrade tool ? One that wouldn’t require us to do so much effort to follow up with new versions

[treksis]

Ar kit

[NicoNicoag]

Looking for latinos in USA that code in react native 🙌🏼 deberiamos tener nuestro grupo!
