@tsai-pe/board-core

Framework-light state and logic for the Pipeline Editor board — pure TypeScript + Angular signals, no templates. Consumed by @tsai-pe/board; usable standalone (headless) too.

Install

npm i @tsai-pe/board-core

Peer deps: @angular/core ^21, @tsai-pe/nodes. @tsai-pe/models is a regular dependency (installed automatically).

Exports

• BoardStore — signal document store: nodes, edges, selection, history (undo/redo), clipboard, viewport; live validation issues, edgeGeometries (routed), ancestorsOf(id), and connection rules (canConnect: output→input, no cycle, fan-in allowed).
• Viewport — pan/zoom, screen ↔ world, zoomAround, fitTo.
• geometry — grid math, nodeRect, portAnchor, rect intersection, bezier edge path, GRID_CELL.
• routing — orthogonal A* edge routing on the 16-unit subgrid (avoids nodes and other edges; bezier fallback).

import { BoardStore } from '@tsai-pe/board-core';

const store = new BoardStore();
const id = store.addNode({ kind: 'trigger', title: 'Telegram', pos: { col: 0, row: 0 } });
