@oh-just-another/types

L0 type vocabulary shared across the diagram library: geometric primitives, identifiers and framework-agnostic input events.

No runtime dependencies. The only runtime value is the shapeId() cast helper.

Exports

| Name | Kind | Notes | | ----------------------------------------------------------------------------------------------------------------- | -------- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | Vec2, Point | type | { readonly x, y: number }. Point is a Vec2 alias for API readability. | | Bounds | type | { x, y, width, height }, DOM-style. width/height may be negative; normalization lives in @oh-just-another/math/bounds. | | Transform | type | 6-component 2D affine matrix { a, b, c, d, e, f }. Maps (x, y) → (a·x + c·y + e, b·x + d·y + f). Compatible with CanvasRenderingContext2D.setTransform and DOMMatrix. | | Color | type | Plain string. Validation/parsing in @oh-just-another/math/color. | | ElementId, LinkId, LayerId | type | Branded string IDs. Each is a distinct nominal type — ElementId is not assignable to LinkId and vice versa. | | elementId(), linkId(), layerId() | function | Cast a raw string to the corresponding branded ID. Caller owns uniqueness. | | Modifiers, PointerEventData, KeyboardEventData, WheelEventData, PointerKind, PointerPhase, KeyPhase | type | Framework-agnostic input events. No DOM types. |
