Yaruil

Yet Another Roblox UI Library Yaruil is fairly simple, it's similar to reactjs and solidjs. If you want JSX, then you will have to install the transformer. With JSX, you'll always want to have the Yauril module imported, import * as Yaruil from "@rbxts/yaruil"

Props and children

Creating an element looks like this: Yaruil.createElement("ScreenGui, {/* props */}, [/* children */]).

Prop values

The value of a prop can be a function or a literal. () => (`count: ${count()}`) or just simply `count: ${count()}`

Examples

Here is an example of a basic component.

import { Players } from "@rbxts/services";
import * as Yaruil from "@rbxts/yaruil";
import { createSignal, render } from "@rbxts/yaruil";
import { childrenLike } from "@rbxts/yaruil/out/util/types";

function Button({ children }: { children?: childrenLike }) {
	const [count, setCount] = createSignal(0);

	return (
		<screengui>
			<textbutton
				on:MouseButton1Click={() => {
					setCount(count() + 1);
				}}
				Size={new UDim2(0, 100, 0, 100)}
				Text={`count: ${count()}`}
			>
                // we dont know if children is defined
				{...children || []}
			</textbutton>
		</screengui>
	);
}
render(
	<Button>
		<uicorner />
	</Button>,
	Players.LocalPlayer.WaitForChild("PlayerGui"),
);

It's relatively easy to communicate state.

import { Players } from "@rbxts/services";
import * as Yaruil from "@rbxts/yaruil";
import { createDependency, render } from "@rbxts/yaruil";
import { externalSignal } from "@rbxts/yaruil/out/hooks/externalSignal";
import { childrenLike } from "@rbxts/yaruil/out/util/types";

export const countSignal = externalSignal(1);
// some event happens...
Event.connect((newValue) => countSignal.set(999))
function Button({ children }: { children?: childrenLike }) {
	const [count, setCount] = createDependency(countSignal);

	return (
		<screengui>
			<textbutton
				on:MouseButton1Click={() => {
					setCount(count() + 1);
				}}
				Size={new UDim2(0, 100, 0, 100)}
				Text={() => `count: ${count()}`}
			>
				{...children || []}
			</textbutton>
		</screengui>
	);
}
