Install

npm install @shapeshift-labs/frontier-canvas @shapeshift-labs/frontier-canvas-tools

Usage

import { createCanvasSurface, createCanvasToolRegistry } from '@shapeshift-labs/frontier-canvas';
import {
  createPaintCanvasTool,
  createFillCanvasTool,
  createCanvasToolsAiManifest
} from '@shapeshift-labs/frontier-canvas-tools';

const tools = [
  createPaintCanvasTool({ value: 'grass', cellsPath: '/level/cells' }),
  createFillCanvasTool({ value: 'water', cellsPath: '/level/cells' })
];

const surface = createCanvasSurface({
  session: { activeToolId: 'canvasTools.paint' },
  tools
});

const registry = createCanvasToolRegistry({ tools, activeToolId: surface.session.activeToolId });
const record = registry.dispatch({
  event: {
    type: 'pointermove',
    previousScreen: { x: 0, y: 0 },
    screen: { x: 32, y: 16 }
  },
  context: {
    surface,
    session: surface.session,
    camera: surface.session.camera,
    viewport: surface.session.viewport
  }
});

const aiTools = createCanvasToolsAiManifest({ tools, namespace: 'editor' });

Tool Set

createPaintCanvasTool paints grid cells with Bresenham line rasterization between pointer samples.
createEraserCanvasTool erases the same rasterized cell path.
createLineCanvasTool commits a Bresenham line from gesture start to end and can emit preview patches.
createRectangleCanvasTool commits filled or outline rectangles.
createFillCanvasTool uses iterative scanline flood fill over a provided cell snapshot.
createEntityBrushCanvasTool places normalized entity/item records with snap and flip controls.
createMoveCanvasTool and createResizeCanvasTool emit transform patches for normalized item maps.
materializeCanvasTransformHandles and hitTestCanvasHandle create reusable move/resize handles.

State Machines

createCanvasToolMachine, selectCanvasTool, setCanvasToolMode, setCanvasToolControl, beginCanvasToolGesture, updateCanvasToolGesture, commitCanvasToolGesture, and cancelCanvasToolGesture model selected tool, per-mode registries, settings, pointer/gesture capture, hover previews, and commit/cancel phases as patchable state.

Tool machines carry a stateScope field. It defaults to local, but can be set to crdt when an app wants selected tool, mode, settings, or committed gesture state to be shared.

CRDT And Local State

createCanvasToolsStateLayout extends the core canvas state layout with tool-specific paths:

/canvas/document/cells, /canvas/document/items, and /canvas/document/itemsById default to crdt.
/canvas/session/toolMachine, /canvas/session/preview, /canvas/session/activeValue, and /canvas/session/toolTasks default to local.

partitionCanvasToolPatches uses that layout to split tool output before it reaches a CRDT adapter or local store:

const layout = createCanvasToolsStateLayout({
  rootPath: '/editor/canvas',
  machineScope: 'crdt'
});

const { crdt, local } = partitionCanvasToolPatches(record.patches, layout);

This keeps Inkwell-style document edits syncable while pointer capture, hover previews, active brush settings, and async task UI state stay local unless explicitly promoted.

AI And Policy

createCanvasToolActions and createCanvasToolsAiManifest convert canvas tools into frontier-tools action manifests with reads, writes, required capabilities, expected patches, controls, icons, and event metadata. canUseCanvasTool and dispatchCanvasToolWithPermissions provide lightweight capability/policy gating.

Research Transfer

Inkwell-style tile tools map to grid-cell patches rather than mutable editor methods.
Bresenham line rasterization is used for brush, eraser, and line tools.
Flood fill uses an iterative scanline queue instead of recursion.
tldraw-style tool/state separation maps to explicit tool-machine records and lifecycle helpers.
Fabric/Konva-style transform handles map to reusable handle materialization and hit testing.

Benchmarks

These are Frontier-only package measurements, not competitor comparisons.

npm run bench

The benchmark covers Bresenham strokes, rectangle cell materialization, scanline fill, tool dispatch, transform handles, tool-machine transitions, and AI manifest generation.

Boundary

frontier-canvas-tools depends on frontier, frontier-canvas, and frontier-tools. It does not import DOM, React, Canvas2D, WebGL, workers, state engines, or app-specific editor runtimes.
