Raisins React

Raisins in a WYSIWYG visual editor for HTML and web components. This is the react package, which handles the state behind the visual rendering experience.

Installation

npm i @raisins/react

Examples

Raisins React comes with many controllers and molecules to help build a visual editor for your HTML. By using each of them together, you are able to control each different piece of functionality to include or exclude from the editing experience.

Base Example

  • The base example contains a canvas with some basic text editability. It can be combined with the examples below to provide a more complete editability experience.
  const WidgetScope = createScope<{
    startingHtml: string;
    startingPackages: Module[];
  }>({
    startingHtml: '',
    startingPackages: [] as Module[],
  });

  const ConfigMolecule = molecule<Partial<RaisinConfig>>((_, getScope) => {
    const widgetScope = getScope(WidgetScope);
    return {
      HTMLAtom: atom(widgetScope.startingHtml),
      PackagesAtom: atom(widgetScope.startingPackages),
      uiWidgetsAtom: atom({}),
    };
  });

  const startingHtml = `
    <h1>My Heading</h1>
    <p style="width:200px;height:100px;">My first paragraph</p>
    <p style="width:200px;height:100px;">My second paragraph</p>
`;

  const Editor = () => {
    useHotkeys();
    return (
      <div style={{ display: 'flex' }}>
        <div style={{ flex: 0.7 }}>
          <BasicCanvasController />
        </div>
        <div style={{ flex: 0.3 }}>
          <AttributeEditor />
        </div>
      </div>
    );
  };

  const AttributeEditor = () => {
    useMolecule(CanvasSelectionMolecule);
    useMolecule(CanvasHoveredMolecule);
    return (
      <SelectedNodeController
        HasSelectionComponent={AttributesController}
      ></SelectedNodeController>
    );
  };

export function BaseExample() {
  return (
    <ScopeProvider
      scope={WidgetScope}
      value={{
        startingHtml,
        startingPackages: [],
      }}
    >
      <RaisinsProvider molecule={ConfigMolecule}>
        <CanvasProvider>
          <Editor />
        </CanvasProvider>
      </RaisinsProvider>
    </ScopeProvider>
  );
}

External HTML Control

  const Editor = () => {
    useHotkeys();
    const { HTMLAtom } = useMolecule(ConfigMolecule);
    const [html, setHtml] = useAtom(HTMLAtom!);

    return (
      <>
        <textarea
          value={html}
          onInput={(e) => setHtml((e.target as HTMLTextAreaElement).value)}
          rows={10}
          style={{ width: '500px' }}
        />
        <div style={{ display: 'flex' }}>
          <div style={{ flex: 0.7 }}>
            <BasicCanvasController />
          </div>
          <div style={{ flex: 0.3 }}>
            <AttributeEditor />
          </div>
        </div>
      </>
    );
  };

Canvas Toolbars

  };

  const { getComponentMeta } = useAtomValue(ComponentModelAtom);
  const hoveredTitle = getComponentMeta(hoveredNode?.tagName).title;
  const selectedTitle = getComponentMeta(selectedNode?.tagName).title;
  return (

      </PositionedToolbar>
      <PositionedToolbar rectAtom={SelectedRectAtom}>
        Selected - {selectedTitle}
        <SelectedNodeRichTextEditor />
      </PositionedToolbar>
    </>
  );
};

  const Editor = () => {
    useHotkeys();
    const { EditSelectedNodeAtom } = useMolecule(EditSelectedMolecule);
    return (
      <>
        <NodeScopeProvider nodeAtom={EditSelectedNodeAtom}>

        </NodeScopeProvider>
        <div style={{ display: 'flex' }}>

          <div style={{ flex: 0.3 }}>
