+- 🎯 **Framework-agnostic** — works with React, Vue, Svelte, Angular or vanilla JS
+- 🧩 **Plugin system** — extensible architecture with ready-to-use plugins
+- 📐 **Complete toolset** — grid, rulers, guides, area selection
+- ⌨️ **Hotkeys** — Ctrl+C/V/X, Delete, Ctrl+G for grouping
+- 🎨 **Rich shapes** — rectangles, circles, text, images, arrows, stars
+- 🔄 **Transformations** — rotation, scaling, movement with aspect ratio lock
+- 📦 **TypeScript-first** — full typing out of the box

-- Dev playground: `npm run dev` or `bun run dev`
-- Build library: `npm run build` or `bun run build`
-- Lint: `npm run lint` or `bun run lint`
-- Typecheck: `npm run typecheck` or `bun run typecheck`
+## 📦 Installation
-The playground imports from `src/` directly for rapid iteration.
+```bash
+npm install @flowscape-ui/core-sdk
+# or
+yarn add @flowscape-ui/core-sdk
+# or
+bun add @flowscape-ui/core-sdk
+```
-Dev server is pinned to `http://localhost:5174/` via `playground/vite.config.ts`.
+## 🚀 Quick Start
-## Branching strategy
+```typescript
+import { CoreEngine, GridPlugin, SelectionPlugin, NodeHotkeysPlugin } from '@flowscape-ui/core-sdk';
-- `dev`: active development branch
-- `main`: protected, merges from `dev`, no auto-publish
-- `release`: dedicated branch for releases
+// Create engine with plugins
+const core = new CoreEngine({
+ container: document.getElementById('canvas-container')!,
+ width: 1200,
+ height: 800,
+ plugins: [
+ new GridPlugin({ enabled: true }),
+ new SelectionPlugin({ dragEnabled: true }),
+ new NodeHotkeysPlugin(), // Ctrl+C/V/X, Delete
+ ],
+});
-Publishing to npm is only possible via the GitHub Actions manual workflow `Publish to npm` with a valid `NPM_TOKEN`. Local `npm publish` is blocked.
+// Add shapes
+const rect = core.nodes.addShape({
+ x: 100,
+ y: 100,
+ width: 200,
+ height: 150,
+ fill: '#3b82f6',
+ cornerRadius: 8,
+});
-## Publishing
+const text = core.nodes.addText({
+ x: 120,
+ y: 140,
+ text: 'Hello Flowscape!',
+ fontSize: 24,
+ fill: 'white',
+});
-Run the GitHub Action: Actions -> Publish to npm -> Run workflow.
-Optionally select a version bump (patch/minor/major). The workflow will build and publish to npm.
+// Grouping
+const group = core.nodes.addGroup({
+ x: 400,
+ y: 200,
+});
+rect.getNode().moveTo(group.getNode());
+text.getNode().moveTo(group.getNode());
+```
-Ensure:
+## 🏗️ Architecture
-- You are on `release` branch or using a release tag.
-- `NPM_TOKEN` secret is configured in the repository.

+### Plugin System
+
+Plugins extend engine functionality without modifying the core:
+
+```typescript
+import { Plugin } from '@flowscape-ui/core-sdk';
+
+class CustomPlugin extends Plugin {
+ protected onAttach(core: CoreEngine): void {
+ // Initialize on attach
+ core.eventBus.on('node:created', (node) => {
+ console.log('Node created:', node);
+ });
+ }
+
+ protected onDetach(core: CoreEngine): void {
+ // Cleanup on detach
+ core.eventBus.off('node:created');
+ }
+}
+
+// Usage
+const core = new CoreEngine({
+ container: element,
+ plugins: [new CustomPlugin()],
+});
+```
+
+### Built-in Plugins
+
+| Plugin | Description |
+| --------------------- | ---------------------------------------- |
+| `GridPlugin` | Adaptive grid with automatic scaling |
+| `SelectionPlugin` | Selection, transformation, drag & drop |
+| `NodeHotkeysPlugin` | Ctrl+C/V/X, Delete, Ctrl+[/] for z-index |
+| `CameraHotkeysPlugin` | Ctrl+wheel for zoom, arrows for pan |
+| `RulerPlugin` | Rulers with measurement units |
+| `RulerGuidesPlugin` | Guide lines (drag from rulers) |
+| `AreaSelectionPlugin` | Area selection with frame (Shift+Drag) |
+| `LogoPlugin` | Watermark/logo on canvas |
+
+## 📚 Usage Examples
+
+### Creating Shapes
+
+```typescript
+// Rectangle with rounded corners
+const rect = core.nodes.addShape({
+ x: 50,
+ y: 50,
+ width: 200,
+ height: 100,
+ fill: '#10b981',
+ cornerRadius: 12,
+});
+
+// Circle
+const circle = core.nodes.addCircle({
+ x: 300,
+ y: 100,
+ radius: 50,
+ fill: '#f59e0b',
+ stroke: '#d97706',
+ strokeWidth: 3,
+});
+
+// Text
+const text = core.nodes.addText({
+ x: 400,
+ y: 50,
+ text: 'Flowscape UI',
+ fontSize: 32,
+ fontFamily: 'Inter',
+ fill: '#1f2937',
+});
+
+// Image
+const image = core.nodes.addImage({
+ x: 100,
+ y: 200,
+ width: 200,
+ height: 150,
+ src: '/path/to/image.jpg',
+});
+```
+
+### Working with Events
+
+```typescript
+// Subscribe to events
+core.eventBus.on('node:created', (node) => {
+ console.log('Node created:', node);
+});
+
+core.eventBus.on('node:selected', (node) => {
+ console.log('Node selected:', node);
+});
+
+core.eventBus.on('camera:zoom', ({ scale }) => {
+ console.log('Zoom changed:', scale);
+});
+
+// Unsubscribe
+const handler = (node) => console.log(node);
+core.eventBus.on('node:created', handler);
+core.eventBus.off('node:created', handler);
+```
+
+### Grouping and Management

+
+### Camera and Navigation
+
+```typescript
+// Programmatic zoom

+core.camera.zoomOut(); // Zoom out
+core.camera.setZoom(1.5); // Set specific scale
+
+// Panning

+core.camera.centerOn(node);
+
+// Reset camera

+# Тесты для Flowscape Core SDK
+
+## Установка зависимостей
+
+```bash
+npm install
+```
+
+## Запуск тестов
+
+### Запуск всех тестов в watch-режиме
+
+```bash
+npm test
+```
+
+### Запуск тестов один раз
+
+```bash
+npm run test:run
+```
+
+### Запуск тестов с UI-интерфейсом
+
+```bash
+npm run test:ui
+```
+
+- **Одиночные ноды:**
+ - Сохранение размеров (width/height)
+ - Сохранение трансформаций (scaleX/scaleY/rotation)
+ - Сохранение визуального размера (width \* scaleX)
+- **Группы:**
+ - Сохранение размеров нод в группе
+ - Сохранение трансформаций группы
+ - Сохранение визуальных размеров в трансформированной группе
+
+- **Вырезание (Cut):**
+ - Сохранение размеров и трансформаций после вырезания/вставки
+
+### `grouping-sizes.test.ts`
+
+Тесты для проверки сохранения размеров при группировке/разгруппировке:
+
+- **Создание группы:**
+ - Сохранение размеров нод при добавлении в группу
+ - Сохранение трансформаций нод
+ - Сохранение визуального размера
+
+- **Трансформация группы:**
+ - Изменение визуального размера нод при трансформации группы
+ - Сохранение соотношения размеров при неравномерной трансформации
+
+- **Разгруппировка:**
+ - Сохранение визуального размера нод
+ - Сохранение трансформаций (композиция трансформаций ноды и группы)
+
+- **Временная группа (Temp Multi Group):**
+ - Сохранение размеров при коммите временной группы в постоянную
+
+- **Сложные сценарии:**
+ - Группировка → трансформация → разгруппировка → копирование
+
+## Что проверяют тесты
+
+### 1. Размеры (width/height)
+
+Проверяется, что базовые размеры нод не изменяются при операциях копирования/группировки.
+
+### 2. Трансформации (scaleX/scaleY/rotation)
+
+Проверяется, что трансформации сохраняются и правильно композируются при вложенных операциях.
+
+### 3. Визуальный размер
+
+Проверяется итоговый визуальный размер ноды на экране (учитывая все трансформации):
+
+```
+visualWidth = width * scaleX
+visualHeight = height * scaleY
+```
+
+### 4. Композиция трансформаций
+
+При вложенных группах проверяется правильная композиция трансформаций:
+
+```
+finalScaleX = nodeScaleX * groupScaleX
+finalRotation = nodeRotation + groupRotation
+```
+
+## Как добавить новые тесты
+
+1. Создайте новый файл `*.test.ts` в директории `tests/`
+2. Импортируйте необходимые модули из `vitest` и SDK
+3. Используйте `describe` для группировки тестов
+4. Используйте `it` или `test` для отдельных тест-кейсов
+5. Используйте `expect` для проверки ожиданий
+
+Пример:
+
+```typescript
+import { describe, it, expect, beforeEach } from 'vitest';
+import { CoreEngine } from '../src/core/CoreEngine';
+
+describe('Моя фича', () => {
+ let core: CoreEngine;
+
+ beforeEach(() => {
+ const container = document.createElement('div');
+ container.style.width = '800px';
+ container.style.height = '600px';
+ document.body.appendChild(container);
+
+ core = new CoreEngine({ container, width: 800, height: 600 });
+ });
+
+ it('должна работать правильно', () => {
+ const node = core.nodes.addShape({ x: 0, y: 0, width: 100, height: 100 });
+ expect(node.getNode().width()).toBe(100);
+ });
+});
+```
+
+## Отладка тестов
+
+### Запуск конкретного теста
+
+```bash
+npm test -- copy-paste-sizes
+```
+
+### Запуск с подробным выводом
+
+```bash
+npm test -- --reporter=verbose
+```
+
+### Отладка в VS Code
+
+Добавьте конфигурацию в `.vscode/launch.json`:
+
+```json
+{
+ "type": "node",
+ "request": "launch",
+ "name": "Debug Vitest Tests",
+ "runtimeExecutable": "npm",
+ "runtimeArgs": ["run", "test"],
+ "console": "integratedTerminal",
+ "internalConsoleOptions": "neverOpen"
+}
+```
+
+## Покрытие кода
+
+После запуска `npm run test:coverage` отчёт будет доступен в директории `coverage/`:
+
+- `coverage/index.html` - визуальный отчёт
+- `coverage/coverage-final.json` - JSON-отчёт
+
+## Проблемы и решения
+
+### Canvas не поддерживается в тестах
+
+Решение: используется mock canvas в `tests/setup.ts`
+
+### Тесты падают с ошибкой "Cannot find module"
+
+Решение: убедитесь, что установлены все зависимости (`npm install`)
+
+### Тесты проходят локально, но падают в CI
+
+Решение: проверьте версии Node.js и зависимостей в CI
