Viewport

Viewport(__namedParameters): ReactElement

Defined in: src/components/primitives/viewport/Viewport.tsx:100

Viewport — pan/zoom canvas + HTML container for editor-style surfaces such as node graphs, timelines, and 2D world editors.

Composes:

  • Multiple perf-isolated <ViewportLayer> canvases (one draw cycle each).
  • <ViewportWorld> for HTML positioned in world coordinates.
  • <ViewportOverlay> for HTML pinned to the viewport (toolbars, minimap).

Owns pan/zoom gestures (drag-to-pan, wheel-zoom-toward-cursor, optional pinch and space-to-pan) and optional marquee selection. Transform is controlled or uncontrolled (useControlledState-style) and mirrored into an internal ViewportStore that powers slice-level subscriptions for layers, world, and overlay children.
