hermes VS glide

Hermes is a big one as well: low startup latency, low memory

Hermes

InstagramBundle.js.hbc.spk.xz is likely a compressed version of Hermes bytecode (js.hbc)"

In React Native's case, it uses an engine called Hermes:

📜 I made JSON.parse() 2x faster: Radek proposes to improve the performance of Hermes by using very fast C++ libs based on SIMD instructions. Interesting to read even if you don't use React-Native. Ongoing discussions on the Hermes PR.

Thanks! There's a preliminary PR with a discussion here: https://github.com/facebook/hermes/pull/933 (and broader context here: https://github.com/facebook/hermes/issues/811 ). But we'll see if there's any interest on Hermes' side to merging it. They definitely want to improve the parser, but it's unclear to me if they want to take on the simdjson/simdutf dependencies.

For me it’s a JS engine for React Natve - https://hermesengine.dev/

💉 Building and injecting a JS bundle a basic concept: If the native code wasn’t changed, simply create JS bundle and inject it into the precompiled application. (You must take an extra step to convert a js file to bytecode if you use the Hermes js engine.)

Do you mean what I use to show the images? I am using the Glide library, you can find more information here: https://github.com/bumptech/glide

as mentioned in the other post i don't have too much insight in the art loading because its using https://github.com/bumptech/glide for all image loading. Resolution is the only thing i know for sure can prevent an imagine from successfully loading, whether or not that resolution is fixed or if its dependent on the device I have not been able to determine

Ah, yes, downloading images as a files works completely differently from displaying images and it doesn't use any cache. Though in theory you could rewrite downloading logic to use the same mechanism as display (which is Glide)

Glide

You can also take a look at Coil, Picasso or Glide which usually have some kind of crossfade animation when the image loads.

Image loading: Glide, Picasso, Coil, Fresco

Shortly said, they use React generally with fast-image and Glide for better loading of images Hermes JS Engine for app optimization. The app itself seems to generally use Kotlin and a few Java libraries and they also implemented Sqlite but I'm not sure about the use case for it probably they use it for progress though (The Developer/Marketer needs to confirm this), lastly they seem to use IntellJ Idea for programming and probably compiling

If you see a file like this: https://github.com/bumptech/glide/blob/master/library/src/main/java/com/bumptech/glide/RequestBuilder.java tell me that your eyes don't immediately go to the comments first instead of the code.
