Now React AppState was migrated to TypeScript!!
This was built by JavaScript + babel + flow until now, But codebase are small enough to rewrite short time, and SWR is good example about npm by TypeScript I came across look 👀

Babel free

TypeScript build stuff is so simple than babel!
Because TypeScript don't need many plugins like babel-plugin-uuuaahh.
Only part you need leaning is Compiler Options that was written on tsconfig.json.
Actually there are many options I couldn't master all in a few days but leaning resource is centralize on the single page docs 📝

Auto generation type definition files

Before migrate I was put in hand made index.d.ts file for TypeScript.
This is so painful to create and has a possibility untrusted 😭

You can ignore annoying type error 😆

This is as same as Flow!
If you faced unessential type system correctness you can ignore that error with // @ts-ignore code comments.

And you can customize how strong typing depends on do you preferred with Compiler Options noImplicitAny setting etc.
I'm grad to I still work with JavaScript that expanded soft typing system 😄🎉

Finaly, I'll more learn about TypeScript Compiler Options, Effective ESLint settings, and be figure out favorite code writing style!
Also I wanna introduce about React AppState after lately, I'm grad if that will useful for developer making small website/webapp! 👨‍💻

Thank you for reading my poor English post! ☕️
Welcome comment feel free If you know more better English, If you know more tech things, or other your special 😀🚀

Nice:) I first saw you on reactiflux, and i'm happy your lib is coming together like that!

 

Thank you!
reactflux forks gave me a lof of feedback that was so useful for improve library.
I appreciate it! 😆
