# Konva.js

> Konva.js is the most popular open-source 2D HTML5 Canvas JavaScript framework. It provides an object-oriented API for canvas graphics with shapes, animations, events, drag-and-drop, filters, and official integrations with React, Vue, Svelte, and Angular. MIT licensed, created in 2014, used by Meta, Microsoft, Labelbox, Zazzle, and thousands of developers.

Konva uses a Stage → Layer → Group → Shape hierarchy. You create a Stage (attached to a DOM container), add Layers (each is a separate `<canvas>` element), and draw Shapes (Rect, Circle, Ellipse, Line, Text, Image, Path, Star, Ring, Arc, Arrow, Label, RegularPolygon, Wedge, Sprite, TextPath) on those layers.

Key capabilities: object-oriented shape management, full event system (click, hover, touch, drag), built-in drag-and-drop, animations and tweens, image filters (blur, brighten, contrast, grayscale, etc.), canvas serialization/deserialization (toJSON/fromJSON), high-quality image export (toDataURL, toBlob), node nesting and grouping, hit detection, and caching for performance.

Framework bindings:

- Vue: `vue-konva` — Vue components for Konva
- Svelte: `svelte-konva` — Svelte components for Konva
- Angular: `ng2-konva` — Angular directives for Konva

# Full API Reference

## Konva (namespace)

### Static Properties
  autoDrawEnabled: any — Should Konva automatically update canvas on any changes. Default is true.
  hitOnDragEnabled: any — Should we enable hit detection while dragging? For performance reasons, by default it is false. But on some rare cases you want to see hit graph and check intersections. Just set it to true.
  capturePointerEventsEnabled: any — Should we capture touch events and bind them to the touchstart target? That is how it works on DOM elements. The case: we touchstart on div1, then touchmove out of that element into another element div2. DOM will continue trigger touchmove events on div1 (not div2). Because events are "captured" into initial target. By default Konva do not do that and will trigger touchmove on another element, while pointer is moving.
  legacyTextRendering: any — Use legacy text rendering. with "middle" baseline by default.
  pixelRatio: any — Global pixel ratio configuration. KonvaJS automatically detect pixel ratio of current device. But you may override such property, if you want to use your value. Set this value before any components initializations.
  dragDistance: any — Drag distance property. If you start to drag a node you may want to wait until pointer is moved to some distance from start point, only then start dragging. Default is 3px.
  angleDeg: any — Use degree values for angle properties. You may set this property to false if you want to use radian values.
  showWarnings: any — Show different warnings about errors or wrong API usage
  dragButtons: any — Configure what mouse buttons can be used for drag and drop. Default value is [0, 1] - left and middle mouse buttons.
  releaseCanvasOnDestroy: any — Should Konva release canvas elements on destroy. Default is true. Useful to avoid memory leak issues in Safari on macOS/iOS.

  position: Object — get/set node position relative to parent
  x: Object — get/set x position
  y: Integer — get/set y position
  globalCompositeOperation: String — get/set globalCompositeOperation of a node. globalCompositeOperation DOESN'T affect hit graph of nodes. So they are still trigger to events as they have default "source-over" globalCompositeOperation.
  opacity: Number — get/set opacity.  Opacity values range from 0 to 1.  A node with an opacity of 0 is fully transparent, and a node  with an opacity of 1 is fully opaque
  name: String — get/set name.

If you need to determine if a node is listening or not   by taking into account its parents, use the isListening() method   nodes with listening set to false will not be detected in hit graph   so they will be ignored in container.getIntersection() method
  preventDefault: Boolean — get/set preventDefault By default all shapes will prevent default behavior of a browser on a pointer move or tap. that will prevent native scrolling when you are trying to drag&drop a node but sometimes you may need to enable default actions in that case you can set the property to false
  filters: Array — get/set filters. Supports function filters, CSS filter strings, or mixed arrays. CSS filters are applied using native browser performance when possible, function filters use ImageData manipulation. CSS filters automatically fall back to function filters in unsupported browsers.

### Methods
  clearCache() → Konva.Node — clear cached canvas
  cache(config?: Object, config.x?: Number, config.y?: Number, config.width?: Number, config.height?: Number, config.offset?: Number, config.drawBorder?: Boolean, config.pixelRatio?: Number, config.imageSmoothingEnabled?: Boolean, config.hitCanvasPixelRatio?: Number) → Konva.Node — cache node to improve drawing performance, apply filters, or create more accurate  hit regions. For all basic shapes size of cache canvas will be automatically detected.  If you need to cache your custom `Konva.Shape` instance you have to pass shape's bounding box  properties. Look at [https://konvajs.org/docs/performance/Shape_Caching.html](https://konvajs.org/docs/performance/Shape_Caching.html) for more information.
  isCached() → Boolean — determine if node is currently cached
  getClientRect(config: Object, config.skipTransform?: Boolean, config.skipShadow?: Boolean, config.skipStroke?: Boolean, config.relativeTo?: Object) → Object — Return client rectangle {x, y, width, height} of node. This rectangle also include all styling (strokes, shadows, etc). The purpose of the method is similar to getBoundingClientRect API of the DOM.
  on(evtStr: String, handler: function) → Konva.Node — bind events to the node. KonvaJS supports mouseover, mousemove,  mouseout, mouseenter, mouseleave, mousedown, mouseup, wheel, contextmenu, click, dblclick, touchstart, touchmove,  touchend, tap, dbltap, dragstart, dragmove, and dragend events.  Pass in a string of events delimited by a space to bind multiple events at once  such as 'mousedown mouseup mousemove'. Include a namespace to bind an  event by name such as 'click.foobar'.
  off(evtStr: String) → Konva.Node — remove event bindings from the node. Pass in a string of  event types delimmited by a space to remove multiple event  bindings at once such as 'mousedown mouseup mousemove'.  include a namespace to remove an event binding by name  such as 'click.foobar'. If you only give a name like '.foobar',  all events in that namespace will be removed.
  remove() → Konva.Node — remove a node from parent, but don't destroy. You can reuse the node later.
  destroy() — remove and destroy a node. Kill it and delete forever! You should not reuse node after destroy(). If the node is a container (Group, Stage or Layer) it will destroy all children too.
  isListening() → Boolean — determine if node is listening for events by taking into account ancestors.  Parent    | Self      | isListening listening | listening | ----------+-----------+------------ T         | T         | T T         | F         | F F         | T         | F F         | F         | F
  isVisible() → Boolean — determine if node is visible by taking into account ancestors.  Parent    | Self      | isVisible visible   | visible   | ----------+-----------+------------ T         | T         | T T         | F         | F F         | T         | F F         | F         | F
  show() → Konva.Node — show node. set visible = true
  hide() → Konva.Node — hide node.  Hidden nodes are no longer detectable
  move(change: Object, change.x: Number, change.y: Number) → Konva.Node — move node by an amount relative to its current position
  rotate(theta: Number) → Konva.Node — rotate node by an amount in degrees relative to its current rotation
  moveToTop() → Boolean — move node to the top of its siblings
  moveUp() → Boolean — move node up
  moveDown() → Boolean — move node down
  moveToBottom() → Boolean — move node to the bottom of its siblings
  moveTo(newContainer: Container) → Konva.Node — move node to another container
  toObject() → Object — convert Node into an object for serialization.  Returns an object.
  toJSON() → String — convert Node into a JSON string.  Returns a JSON string.
  fire(eventType: String, evt?: Event, bubble?: Boolean) → Konva.Node — fire event
  clone(obj: Object) → Konva.Node — clone node.  Returns a new Node instance with identical attributes.  You can also override  the node properties with an object literal, enabling you to use an existing node as a template  for another node
  toCanvas(config: Object, config.callback: function, config.x?: Number, config.y?: Number, config.width?: Number, config.height?: Number, config.pixelRatio?: Number, config.imageSmoothingEnabled?: Boolean) — converts node into an canvas element.
  toDataURL(config: Object, config.mimeType?: String, config.x?: Number, config.y?: Number, config.width?: Number, config.height?: Number, config.quality?: Number, config.pixelRatio?: Number, config.imageSmoothingEnabled?: Boolean) → String — Creates a composite data URL (base64 string). If MIME type is not specified, then "image/png" will result. For "image/jpeg", specify a quality level as quality (range 0.0 - 1.0)
  toImage(config: Object, config.callback?: function, config.mimeType?: String, config.x?: Number, config.y?: Number, config.width?: Number, config.height?: Number, config.quality?: Number, config.pixelRatio?: Number, config.imageSmoothingEnabled?: Boolean) → Promise.<Image> — converts node into an image.  Since the toImage  method is asynchronous, the resulting image can only be retrieved from the config callback  or the returned Promise.  toImage is most commonly used  to cache complex drawings as an image so that they don't have to constantly be redrawn
  toBlob(config: Object, config.callback?: function, config.x?: Number, config.y?: Number, config.width?: Number, config.height?: Number, config.pixelRatio?: Number, config.imageSmoothingEnabled?: Boolean) → Promise.<Blob> — Converts node into a blob.  Since the toBlob method is asynchronous,  the resulting blob can only be retrieved from the config callback  or the returned Promise.
  addName(name: String) → Konva.Node — add name to node
  hasName(name: String) → Boolean — check is node has name
  removeName(name: String) → Konva.Node — remove name from node
  draw() → Konva.Node — draw both scene and hit graphs.  If the node being drawn is the stage, all of the layers will be cleared and redrawn
  startDrag() — initiate drag and drop.
  stopDrag() — stop drag and drop
  isDragging() — determine if node is currently in drag and drop mode
  isClientRectOnScreen(margin: Number | Object, margin.x: Number, margin.y: Number) → Boolean — determine if node (at least partially) is currently in user-visible area
  Node.create(json: String | Object, container?: Element) — create node with JSON string or an Object.  De-serializtion does not generate custom  shape drawing functions, images, or event handlers (this would make the  serialized object huge).  If your app uses custom shapes, images, and  event handlers (it probably does), then you need to select the appropriate  shapes after loading the stage and set these properties via on(), setSceneFunc(),  and setImage() methods
  to(params?: Object) — Tween node properties. Shorter usage of {@link Konva.Tween} object.

### Properties (getter/setter)
  getAllIntersections: Array — get all shapes that intersect a point.  Note: because this method must clear a temporary canvas and redraw every shape inside the container, it should only be used for special situations because it performs very poorly.  Please use the {@link Konva.Stage#getIntersection} method if at all possible because it performs much better nodes with listening set to false will not be detected
  clip: Object — get/set clip
  clipX: Number — get/set clip x
  clipY: Number — get/set clip y
  clipWidth: Number — get/set clip width
  clipHeight: Number — get/set clip height

  removeChildren() — remove all children. Children will be still in memory. If you want to completely destroy all children please use "destroyChildren" method instead
  destroyChildren() — destroy all children nodes.
  add(children: Konva.Node) → Container — add a child and children into container
  find(selector: String | function) → Array — return an array of nodes that match the selector. You can provide a string with '#' for id selections and '.' for name selections. Or a function that will return true/false when a node is passed through.  See example below. With strings you can also select by type or class name. Pass multiple selectors separated by a comma.
  findOne(selector: String | function) → Konva.Node | Undefined — return a first node from `find` method
  isAncestorOf(node: Konva.Node) — determine if node is an ancestor of descendant

    dragBoundFunc: function (optional)

### Properties (getter/setter)
  setContainer: DomElement — set container dom element which contains the stage wrapper div element
  getIntersection: Konva.Node — get visible intersection shape. This is the preferred  method for determining if a point intersects a shape or not nodes with listening set to false will not be detected
  container: DomElement — get/set container DOM element

### Methods
  clear() — clear all layers
  getPointerPosition() → Vector2d | null — returns ABSOLUTE pointer position which can be a touch position or mouse position pointer position doesn't include any transforms (such as scale) of the stage it is just a plain position of pointer relative to top-left corner of the canvas
  getLayers() — returns an array of layers
  setPointersPositions(event: Object) — manually register pointers positions (mouse/touch) in the stage. So you can use stage.getPointerPosition(). Usually you don't need to use that method because all internal events are automatically registered. It may be useful if event is triggered outside of the stage, but you still want to use Konva methods to get pointers position.
  batchDraw() → Konva.Stage — batch draw

### Example
```javascript
var stage = new Konva.Stage({
  width: 500,
  height: 800,
  container: 'containerId' // or "#containerId" or ".containerClass"
});
```

## Konva.Layer extends Konva.Container

Layer constructor.  Layers are tied to their own canvas element and are used to contain groups or shapes.

  height: Number — get/set height of layer.getter return height of stage. setter doing nothing. if you want change height use `stage.height(value);`
  getIntersection: Konva.Node — get visible intersection shape. This is the preferred method for determining if a point intersects a shape or not also you may pass optional selector parameter to return ancestor of intersected shape nodes with listening set to false will not be detected
  imageSmoothingEnabled: Boolean — get/set imageSmoothingEnabled flag For more info see https://developer.mozilla.org/en-US/docs/Web/API/CanvasRenderingContext2D/imageSmoothingEnabled
  clearBeforeDraw: Boolean — get/set clearBeforeDraw flag which determines if the layer is cleared or not  before drawing
  hitGraphEnabled: Boolean — get/set hitGraphEnabled flag.  **DEPRECATED!** Use `layer.listening(false)` instead.  Disabling the hit graph will greatly increase  draw performance because the hit graph will not be redrawn each time the layer is  drawn.  This, however, also disables mouse/touch event detection

### Methods
  batchDraw() → Konva.Layer — batch draw. this function will not do immediate draw but it will schedule drawing to next tick (requestAnimFrame)
  enableHitGraph() → Layer — enable hit graph. **DEPRECATED!** Use `layer.listening(true)` instead.
  disableHitGraph() → Layer — disable hit graph. **DEPRECATED!** Use `layer.listening(false)` instead.
  toggleHitCanvas() — Show or hide hit canvas over the stage. May be useful for debugging custom hitFunc

### Example
```javascript
var layer = new Konva.Layer();
stage.add(layer);
// now you can add shapes, groups into the layer
```

## Konva.FastLayer extends Konva.Layer

FastLayer constructor. **DEPRECATED!** Please use `Konva.Layer({ listening: false})` instead. Layers are tied to their own canvas element and are used to contain shapes only.  If you don't need node nesting, mouse and touch interactions, or event pub/sub, you should use FastLayer instead of Layer to create your layers. It renders about 2x faster than normal layers.

  Constructor config:

### Methods
  getContext()

  hasFill() → Boolean — returns whether or not the shape will be filled
  hasStroke() → Boolean — returns whether or not the shape will be stroked
  intersects(point: Object, point.x: Number, point.y: Number) → Boolean — determines if point is in the shape, regardless if other shapes are on top of it.  Note: because  this method clears a temporary canvas and then redraws the shape, it performs very poorly if executed many times  consecutively.  Please use the {@link Konva.Stage#getIntersection} method if at all possible  because it performs much better
  getSelfRect() → Object — return self rectangle (x, y, width, height) of shape. This method are not taken into account transformation and styles.
  drawHitFromCache(alphaThreshold: Integer) → Konva.Shape — draw hit graph using the cached scene canvas
  strokeHitEnabled(strokeHitEnabled: Boolean) → Boolean — **deprecated, use hitStrokeWidth instead!** get/set strokeHitEnabled property. Useful for performance optimization. You may set `shape.strokeHitEnabled(false)`. In this case stroke will be no draw on hit canvas, so hit area of shape will be decreased (by lineWidth / 2). Remember that non closed line with `strokeHitEnabled = false` will be not drawn on hit canvas, that is mean line will no trigger pointer events (like mouseover) Default value is true.

### Example
```javascript
var customShape = new Konva.Shape({
  x: 5,
  y: 10,
  fill: 'red',
  // a Konva.Canvas renderer is passed into the sceneFunc function
  sceneFunc (context, shape) {

    context.lineTo(420, 80);
    context.quadraticCurveTo(300, 100, 260, 170);
    context.closePath();
    // Konva specific method
    context.fillStrokeShape(shape);
  }
});

  direction: String — get/set direction
  fontFamily: String — get/set font family
  fontSize: Number — get/set font size in pixels
  fontStyle: String — get/set font style.  Can be 'normal', 'italic', or 'bold', '500' or even 'italic bold'.  'normal' is the default.
  fontVariant: String — get/set font variant.  Can be 'normal' or 'small-caps'.  'normal' is the default.
  padding: Number — get/set padding
  align: String — get/set horizontal align of text.  Can be 'left', 'center', 'right' or 'justify'

  lineHeight: Number — get/set line height.  The default is 1.
  wrap: String — get/set wrap.  Can be "word", "char", or "none". Default is "word". In "word" wrapping any word still can be wrapped if it can't be placed in the required width without breaks.
  ellipsis: Boolean — get/set ellipsis. Can be true or false. Default is false. If ellipses is true, Konva will add "..." at the end of the text if it doesn't have enough space to write characters. That is possible only when you limit both width and height of the text

  charRenderFunc: function — get/set per-character render hook. The callback is invoked for each grapheme before drawing. It can mutate the provided context (e.g. translate, rotate, change styles) and should return void. Note: per-character rendering may disable native kerning/ligatures.

### Methods
  measureSize(text: String) → Object — measure string with the font of current text shape. That method can't handle multiline text.
  _shouldHandleEllipsis(currentHeightPx: Number) → Boolean — whether to handle ellipsis, there are two cases: 1. the current line is the last line 2. wrap is NONE

### Example
```javascript
var text = new Konva.Text({
  x: 10,
  y: 15,
  text: 'Simple Text',
  fontSize: 30,

var tween = new Konva.Tween({
  // list of tween specific properties
  node: node,
  duration: 1,
  easing: Konva.Easings.EaseInOut,
  onUpdate: () => console.log('node attrs updated')
  onFinish: () => console.log('finished'),

```

## Konva.Canvas

Canvas Renderer constructor. It is a wrapper around native canvas element. Usually you don't need to use it manually.

  Constructor config:
    width: Number
    height: Number
    pixelRatio: Number

### Properties (getter/setter)
  getContext: CanvasContext — get canvas context
  getPixelRatio: Number — get pixel ratio
  setPixelRatio: Number — set pixel ratio KonvaJS automatically handles pixel ratio adustments in order to render crisp drawings  on all devices. Most desktops, low end tablets, and low end phones, have device pixel ratios  of 1.  Some high end tablets and phones, like iPhones and iPads have a device pixel ratio  of 2.  Some Macbook Pros, and iMacs also have a device pixel ratio of 2.  Some high end Android devices have pixel  ratios of 2 or 3.  Some browsers like Firefox allow you to configure the pixel ratio of the viewport.  Unless otherwise  specificed, the pixel ratio will be defaulted to the actual device pixel ratio.  You can override the device pixel  ratio for special situations, or, if you don't want the pixel ratio to be taken into account, you can set it to 1.

### Methods
  toDataURL(mimeType: String, quality: Number) → String — to data url

## Konva.Context
