Introduction to Remain - React Starter Kit for WordPress

As a developer, you're probably familiar with the challenges of building a WordPress website that integrates with React. Traditionally, WordPress and React are two separate ecosystems that require a significant amount of setup and configuration to work together seamlessly. However, with the Remain - React Starter Kit, you can now create a WordPress website with React components and enjoy the benefits of both worlds.

The Remain - React Starter Kit is a pre-built framework that allows you to create a WordPress website using React components, without requiring you to write custom WordPress code. This means you can focus on building your application without worrying about the underlying WordPress infrastructure. In this tutorial, we'll walk you through the steps of setting up and using the Remain - React Starter Kit for WordPress.

Prerequisites

Before you start, make sure you have the following:

• WordPress installed on your local machine or a production environment
• Node.js installed on your machine
• A code editor or IDE of your choice
• Basic knowledge of React and WordPress development

Step 1: Install the Remain - React Starter Kit

To install the Remain - React Starter Kit, follow these steps:

1. Open your terminal and navigate to the root directory of your WordPress project.
2. Run the following command to install the Remain - React Starter Kit:

   npx @remain/react-starter-kit@latest

   This will install the starter kit and its dependencies.

Step 2: Configure the Starter Kit

After installation, you'll need to configure the starter kit to work with your WordPress project. Follow these steps:

1. Open the config.js file located in the src directory of your project.
2. Update the wpUrl property to point to your WordPress installation. For example:

   export const config = {
   //... other config options...
   wpUrl: 'http://localhost/wordpress'
   };

   Replace http://localhost/wordpress with the URL of your WordPress installation.

Step 3: Create a React Component

Now that the starter kit is configured, let's create a simple React component to get started. Follow these steps:

1. Open the src directory and create a new file called components/HelloWorld.js.
2. Add the following code to the file:

   
   import React from 'react';

const HelloWorld = () => { return

Hello, World!

export default HelloWorld;

This is a simple React component that displays a heading.

**Step 4: Register the Component with WordPress**

To register the component with WordPress, follow these steps:

1. Open the `registerComponents.js` file located in the `src` directory.
2. Add the following code to the file:
```javascript
import React from 'react';
import HelloWorld from './components/HelloWorld';

const registerComponents = () => {
  return [
    {
      component: HelloWorld,
      name: 'hello-world',
      type: 'component',
    },
  ];
};

export default registerComponents;

This code registers the HelloWorld component with WordPress.

Step 5: Use the Component in WordPress

Finally, let's use the component in WordPress. Follow these steps:

1. Open the page.php file located in the wp-content/themes/your-theme directory (replace your-theme with the name of your theme).
2. Add the following code to the file:

   
   <?php
   get_header();
   ?>

<?php get_footer(); ?>

This code adds a div with an ID of `hello-world` to the page.

**Step 6: Load the Component in WordPress**

To load the component in WordPress, follow these steps:

1. Open the `functions.php` file located in the `wp-content/themes/your-theme` directory (replace `your-theme` with the name of your theme).
2. Add the following code to the file:
```php
add_action('wp_footer', 'load_hello_world_component');
function load_hello_world_component() {
 ?>
  <script>
    import React from 'react';
    import ReactDOM from 'react-dom';
    import HelloWorld from '<?php echo get_template_directory_uri();?>/react-components/HelloWorld';

    ReactDOM.render(<HelloWorld />, document.getElementById('hello-world'));
  </script>
  <?php
}

This code loads the HelloWorld component in the hello-world div.
