## Installation

You can install `react-konva-to-svg` using npm, yarn, or directly from GitHub.

- **npm**: `npm install react-konva-to-svg`

- **yarn**: `yarn add react-konva-to-svg`

- **GitHub**: [GitHub Repository](https://github.com/dendrofen/react-konva-to-svg)

## Usage

To use `react-konva-to-svg`, import the library and utilize the `exportStageSVG` function with your Konva stage object. This function allows you to customize the export process.

### `exportStageSVG(stage, blob, options)`

- `stage`: The Konva stage object you want to export.

- `blob` (optional): Set to `true` to export as Blob SVG, or `false` (default) to export as text SVG.

- `options` (optional): An object containing the following callbacks:

  - `onBefore`: A callback function called before export. Receives an array `[stage, layer]` as an argument.

  - `onAfter`: A callback function called after export. Receives an array `[stage, layer]` as an argument.

**Example usage:**

```javascript

import { exportStageSVG } from 'react-konva-to-svg';

// Example usage

const stage = /* your Konva stage */;

const result = await exportStageSVG(stage, false, {

  onBefore: ([stage, layer]) => {

    // Perform actions before export

  },

  onAfter: ([stage, layer]) => {

    // Perform actions after export

  },

});

```

## Compatibility Notice

#### Node or group does not rendering properly

If some of nodes, or any group does not rendering properly - use node [caching](https://konvajs.org/docs/performance/Shape_Caching.html) for incorrect rendered node withing **onBefore** function.
