4. EditableComponent: A wrapper component provided by AEM React Editable Components v2 that makes React components editable within the AEM SPA Editor.
5. MapTo: A decorator function used to map React components to AEM resource types, enabling AEM to recognize and render these components based on their resource type.

Detailed Explanation

AEM React Editable Components v2 enables the integration of React components with AEM’s SPA Editor, allowing for in-context content editing. This integration is achieved through several core components and configurations:

Dependencies and Setup

To start using AEM React Editable Components v2, ensure that your React application is running on Node.js 14 or later. The key dependencies required include:

• @adobe/aem-react-editable-components: Provides the editable components and utilities for integration with AEM.
• @adobe/aem-spa-component-mapping: Manages the mapping between AEM components and React components.
• @adobe/aem-spa-page-model-manager: Handles the retrieval and management of AEM page models.

In your package.json, include the following dependencies:

jsonCopy code{
  "dependencies": {
    "@adobe/aem-react-editable-components": "^2.0.1",
    "@adobe/aem-spa-component-mapping": "^1.1.1",
    "@adobe/aem-spa-page-model-manager": "^1.4.4"
  }
}

SPA Editor Integration

When integrating AEM React Editable Components v2 with a SPA Editor-based React application, the AEM ModelManager SDK is used to retrieve and manage content from AEM. The React app should be wrapped with an initialized ModelManager and include a <Page> component exported from @adobe/aem-react-editable-components. This component handles the dynamic creation of React components based on the JSON representation provided by AEM.

In your src/index.js file:

javascriptCopy codeimport { Constants, ModelManager } from '@adobe/aem-spa-page-model-manager';
import { Page } from '@adobe/aem-react-editable-components';
import { BrowserRouter as Router } from 'react-router-dom';
import { render } from 'react-dom';

document.addEventListener('DOMContentLoaded', () => {
  ModelManager.initialize().then(pageModel => {
    const history = createBrowserHistory();
    render(
      <Router history={history}>
        <Page
          history={history}
          cqChildren={pageModel[Constants.CHILDREN_PROP]}
          cqItems={pageModel[Constants.ITEMS_PROP]}
          cqItemsOrder={pageModel[Constants.ITEMS_ORDER_PROP]}
          cqPath={pageModel[Constants.PATH_PROP]}
          locationPathname={window.location.pathname}
        />
      </Router>,
      document.getElementById('spa-root')
    );
  });
});

The <Page> component dynamically renders React components based on the JSON data from AEM, using the resourceType to map to the appropriate React component.

Creating Editable Components

To create editable components, use the EditableComponent wrapper from @adobe/aem-react-editable-components. Here’s how you can set up an editable component:

1. Define the Component and Edit ConfigurationjavascriptCopy codeimport React from 'react'; import { EditableComponent, MapTo } from '@adobe/aem-react-editable-components'; export const ExampleEditConfig = { emptyLabel: "Example component", isEmpty: function (props) { return props?.message?.trim().length < 1; } }; export const Example = (props) => { if (ExampleEditConfig.isEmpty(props)) { return null; } return (<p className="example__message">{props.message}</p>); }; const EditableExample = (props) => { return ( <EditableComponent config={ExampleEditConfig} {...props}> <Example {...props} /> </EditableComponent> ); }; export default MapTo("wknd-examples/components/example")(EditableExample); This setup ensures that your React component can be edited within AEM SPA Editor and is mapped to a specific AEM resource type.

Embedding Components

Editable components can be embedded within each other. Key considerations include:

• Data Requirements: Ensure that the JSON data from AEM includes content for embedded components.
• Non-Editable Instances: Use the non-editable version of the embedded component to avoid conflicts with the SPA Editor.

Example of an embedding component:

javascriptCopy codeimport React from "react";
import { EditableComponent, MapTo } from "@adobe/aem-react-editable-components";
import { Example } from "./Example.js";

export const EmbeddingEditConfig = {
  emptyLabel: "Embedding component",
  isEmpty: function (props) {
    return props?.title?.trim().length < 1;
  }
};

export const Embedding = (props) => {
  if (EmbeddingEditConfig.isEmpty(props)) { return null; }
  return (
    <div className="embedding">
      <Example message={props.message}/>
      <p className="embedding__title">{props.title}</p>
    </div>
  );
};

const EditableEmbedding = (props) => {
  return (
    <EditableComponent config={EmbeddingEditConfig} {...props}>
      <Embedding {...props} />
    </EditableComponent>
  );
};

export default MapTo("wknd-examples/components/embedding")(EditableEmbedding);

Best Practices or Tips

1. Keep Dependencies Updated: Ensure you use compatible versions of dependencies to avoid conflicts and take advantage of the latest features and bug fixes.
2. Consistent Component Mapping: Maintain consistent mapping between AEM resource types and React components to avoid discrepancies and ensure smooth content rendering.
3. Test Thoroughly: Regularly test your editable components in both development and production environments to ensure they behave as expected within the AEM SPA Editor and the live application.
4. Optimize Performance: Be mindful of the performance impact when rendering complex components or large amounts of data. Optimize components and reduce unnecessary re-renders.
