Examples

Custom render user elements

By default, every user element is rendered just as it is. However, if you'd like to, for example, wrap every user element inside a div, you can do so through the onRender prop:

import {Editor} from "@craftjs/core";

const RenderNode = ({element}) => {
  return (
    <div style={{background: "#000", padding: "5px" }}>
      {element}
    </div>
  )
}

const App = () => {
  return (
    <Editor onRender={RenderNode}>
      <Frame resolver={{Hero}}>
        <Element>
          <h1>Hi</h1>
          <Hero />
        </Element>
      </Frame>
    </Editor>
  )
}

In the above example, every user element will now be wrapped in a black div.

Specifying the Drop Indicator colour

You could change the colours of the drag and drop indicators like so:

import {Editor} from "@craftjs/core";

const App = () => {
  return (
    <Editor
      indicator={{
        'success': '#2d9d78', // green
        'error': '#e34850' // red
      }}
    >
      <Frame resolver={{Hero}}>
        <Element>
          <h1>Hi</h1>
          <Hero />
        </Element>
      </Frame>
    </Editor>
  )
}

Callback when Nodes change

Perform a callback whenever the Nodes in the editor is updated/changed

import {Editor} from "@craftjs/core";

const App = () => {
  return (
    <Editor
      // Save the updated JSON whenever the Nodes has been changed
      onNodesChange={query => {
        const json = query.serialize();
        // save to server
        axios.post('/saveJSON', { json });
      }}
    >
      ..
    </Editor>
  )
}

Override default event handlers

Customize how the default event handlers are handled

import {
  DefaultEventHandlers,
  DefaultEventHandlersOptions,
  Editor,
  EditorStore,
  NodeId
} from '@craftjs/core'

class CustomEventHandlers extends DefaultEventHandlers {
  handlers() {
    const defaultHandlers = super.handlers()

    return {
      ...defaultHandlers,
      // Customize the hover event handler
      hover: (el: HTMLElement, id: NodeId) => {
        const unbindDefaultHoverHandler = defaultHandlers.hover(el, id)

        // Track when the mouse leaves a node and remove the hovered state
        const unbindMouseleave = this.addCraftEventListener(el, 'mouseleave', (e) => {
          e.craft.stopPropagation()
          this.options.store.actions.setNodeEvent('hovered', '')
          console.log(`mouseleave node ${id}`)
        })

        return () => {
          unbindDefaultHoverHandler();
          unbindMouseleave();
        }
      }
    }
  }
}

const App = () => {
  return (
    <Editor
      // Use your own event handlers
      handlers={(store) =>
        new CustomEventHandlers({ store, isMultiSelectEnabled: () => false })
      }
    >
      ...
    </Editor>
  )
}
