After that, you will be asked how you would like to set up your project. We will choose the following options:

? Do you want to use the default database (sqlite) ? Yes
? Start with an example structure & data? Yes <-- make sure you say yes 
? Start with Typescript? Yes
? Install dependencies with npm? Yes
? Initialize a git repository? Yes

Once everything is set up and all the dependencies are installed, you can start your Strapi server with the following command:

cd server
npm run develop

You will be greeted with the Admin Create Account screen.

Go ahead and create your first Strapi user. All of this is local so you can use whatever you want.

Once you have created your user, you will be redirected to the Strapi Dashboard screen.

Publish Article Entries

Since we created our app with the example data, you should be able to navigate to your Article collection and see the data that was created for us.

Now, let's make sure that all of the data is published. If not, you can select all items via the checkbox and then click the Publish button.

Enable API Access

Once all your articles are published, we will expose our Strapi API for the Articles Collection. This can be done in Settings -> Users & Permissions plugin -> Roles -> Public -> Article.

You should have find and findOne selected. If not, go ahead and select them.

Test API

Now, if we make a GET request to http://localhost:1337/api/articles, we should see the following data for our articles.

🖐️ Note: The article covers (images) are not returned. This is because the REST API by default does not populate any relations, media fields, components, or dynamic zones.. Learn more about REST API: Population & Field Selection.

So, let's get the article covers by using the populate=* parameter: http://localhost:1337/api/articles?populate=*

Getting Started with Lexical

Combining Lexical with Strapi creates a powerful rich text editing experience for your content management system. Here's how to set everything up quickly.

Installing Lexical and Adjusting Settings in Strapi

Let's get Lexical installed in your Strapi project:

1. Open your terminal and navigate to your Strapi project root.
2. Install the required packages:

npm install lexical @lexical/react

3. To configure various aspects of Strapi's admin panel, you may update ./config/admin.js with the following code:

module.exports = ({ env }) => ({
 webpack: (config) => {
   config.resolve.alias['lexical'] = require.resolve('lexical');
   return config;
 },
});

For specific integrations or customizations like Lexical, additional steps or specific resources might be necessary. 4. Generate a plugin for your Lexical integration:

yarn strapi generate plugin

or

npm run strapi generate plugin

Then, name the plugin when prompted. 5. Enable your new plugin in ./config/plugins.js:

module.exports = {
 'lexical-editor': {
   enabled: true,
   resolve: './src/plugins/lexical-editor'
 }
};

6. To create or add custom field types for Lexical, consult the software's documentation or contact their support team for guidance.

To enhance your productivity, consider exploring Strapi plugins for productivity and installing essential Strapi plugins that can streamline your development process.

Code Implementation for Integrating Lexical with Strapi

Here's how to bring everything together with actual code to integrate Lexical with Strapi:

First, create a basic Lexical editor component:

import React from 'react';
import { LexicalComposer } from '@lexical/react/LexicalComposer';
import { RichTextPlugin } from '@lexical/react/LexicalRichTextPlugin';
import { ContentEditable } from '@lexical/react/LexicalContentEditable';
import { HistoryPlugin } from '@lexical/react/LexicalHistoryPlugin';

const LexicalField = ({ attribute, onChange, name, value }) => {
  const initialConfig = {
    namespace: 'MyEditor',
    onError: (error) => console.error(error),
  };

  return (
    <LexicalComposer initialConfig={initialConfig}>
      <RichTextPlugin
        contentEditable={<ContentEditable />}
        placeholder={<div>Enter some text...</div>}
      />
      <HistoryPlugin />
    </LexicalComposer>
  );
};

export default LexicalField;

Next, register your custom field in the plugin's index file:

import pluginPkg from '../../package.json';
import LexicalField from './components/LexicalField';
import pluginId from './pluginId';

export default {
  register(app) {
    app.addFields({ type: 'lexical', Component: LexicalField });
  },
  bootstrap(app) {},
};

To save content changes, use the OnChangePlugin with an onChange handler in a LexicalComposer component:

// Import OnChangePlugin
import { OnChangePlugin } from '@lexical/react/LexicalOnChangePlugin';

// Add change handler function
const handleChange = (editorState) => {
  onChange({ target: { name, value: JSON.stringify(editorState) } });
};

// Add this inside your LexicalComposer component
<OnChangePlugin onChange={handleChange} />

Finally, adjust your API controller to manage data effectively:

module.exports = {
  async find(ctx) {
    const entities = await strapi.services['api::article.article'].find(ctx.query);
    return entities.map(entity => ({
      ...entity,
      content: entity.content // Ensure appropriate handling of content
    }));
  },
};

Remember to restart your Strapi server after these changes. Additionally, you might consider building a custom loader for Strapi to enhance data fetching capabilities.

According to JavaScript Plain English, this setup gives you a solid foundation to integrate Lexical with Strapi as your rich text editor.

You're done, congrats!
