Today I learned that if you don't want to emit internal types from a library, you can set `stripInternal` to true in TypeScript config and add a `@ internal` comment:

Let's have fun today and think how we can pass the type to generic type in TypeScript later ⬇️

One small quality of life improvement for frontend devs in TypeScript 4.3: you can now jump into imported files TypeScript doesn’t understand, like CSS.

This is actually _really good_ and there are times when defining your types in terms of an existing value is the 100% best thing you can do 1/

Do you remember the difference between unknown and any in #typescript? 🥇 You can assign anything to unknown and any. 🥈 You can't assign unknow to anything except of unknow and any. 🥉 You can't access unknow properties (unlike any).

Lately, I started digging deep into @github Actions. The way how most actions end up placing build artifacts on the default branch was driving me mad. In this article, I explain how we can use GitHub Actions to develop GitHub Actions and fix it! 👇👇👇 dev.to/krzkaczor/fixi…

By default, TypeScript WON'T throw compilation errors on unreachable code 😱 You might want to tweak that! Just set `"allowUnreachableCode": false` in tsconfig.json typescriptlang.org/tsconfig#allow…

Tip: make sure your declaration files are type-checked. Compile-time errors in unchecked *d.ts files can hide real bugs and lead to painful debugging sessions. Thread 🧵

Use auxiliary package.json to avoid "deep" import paths to your npm packages. This is a great solution if you want to clearly divine public/internal interface of your project. h/t @PSzlachciak 👇👇👇
