HELP!!! I need a better name for this client. (TeleKram is taken)

The app is heavily inspired by Telegram Web K and the dead WhatsApp client for KaiOS.

Additional Info

• First launch of the app might take a while, the next app launches will not take so long.
• Currently Forum Groups will act in a unstable "View as Messages" view as in the Telegram Web K client.
• You must click Enable Push Notifications multiple times until you see a confirmation.
• pre-optimized lottie stickers are pre-converted apng images so client side rendering is not an issue, those stickers can be found in kaigram-assets, non optimized stickers will run at a very horrible fps
• using this app on a 256MB RAM KaiOS device is kinda unstable.

Experimental Low Memory mode

• this mode is now disabled
• the chat list will render only 10 chats and scrolling down will render more
• if the app still crashes, please contact the dev.

Developing

Install NodeJS (v18 or latest LTS) and bun.

Please create a .env.local file and add the values in .env replacing the APP_ID and APP_HASH with your own.

You must use bun!

Dev Mode:

Note

There is an unresolved issue with 2fa when using the dev mode, I have no idea what's wrong with it, works fine on KaiOS 2.5.

bun run dev

Build:

bun run build

After building, you can now sideload the dist folder using WebIDE.

add the :v3 suffix for KaiOS 3.0 (example: bun run dev:v3)

Technical Info

• For KaiOS 2.5, the app utilizes real asm.js and on KaiOS 3.0 it uses WebAssembly like normal.
• mtcute is modified to use jsbi, this means BigInt can be used in KaiOS 2.5 and native BigInts are used for KaiOS 3.0.
• mtcute is also modified in order for asm.js to be used.
• there are 3 Web Workers
  • mtcute web worker proxy
  • heavy tasks worker for blocking operations (webp to png, md5, etc.)
  • rlottie
• SystemJS is used to simulate esm modules on KaiOS 2.5, it is also used to import asm.js files in order for it to preserve asm.js syntax.
