MIT licensed, pre-1.0 and very open to feedback.

A small runtime-validation detail I like

nickname?: string | null

actually contains two separate contracts.

The key may be absent.

And if it exists, the value may be `null`.

That’s why I prefer keeping key-level optionality and value-level nullability explicit. 👀

Canvasで斜め見下ろしの店内を描いて、人が歩く待ち行列シミュレーションを作りました。

・描画順は「一番手前の角」で決め、長い台は1マスずつ割る
・計算の時計と画面の時計を分ける（歩く時間は待ち時間に足さない）
・動きのテストは「止まっていること」で確かめる

What if TypeScript could catch that type-guard drift for you?

With `typedStruct<User>()`, the existing type becomes a compile-time contract for the guard definition.

Missing field? Error.
Wrong guard? Error.

Runtime checks stay explicit. 👀

What if the existing TypeScript type could act as a compile-time contract for your runtime guard?

That’s what I wanted from `typedStruct<User>()`.

The runtime checks are still explicit, but missing or incompatible fields become TypeScript errors instead of silent drift. 👀

Iterator helpers just landed in all major browsers—you can now chain `.map().filter().take()` natively without evaluating the entire array, finally killing those lodash chains you've been lugging around.

I never touched #TypeScript nor docker before. Had zero experience with #NGINX, #react, #FastApi, or more or less anything I touched here. It was hell of fun.
Really looking forward to expanding it.
