• If the DATABASE_URL starts with postgres:// (Heroku's default), it replaces it with the correct format, postgresql+psycopg2://, making the URI compatible with SQLAlchemy.

Instead of manually replacing the URI, you can use libraries like dj-database-url to parse and adapt the DATABASE_URL for different frameworks or drivers. However, the manual approach is straightforward and works well for most cases.

• Backup: Make sure you have a backup of your database and uploads folder before running this script.
• Use on a staging site: Test it on a staging environment before running on a live site, as it will permanently delete all posts and their uploads.

This script will ensure that both the posts and their associated media files are removed from the WordPress database and the filesystem.

• Copy and Paste in tmux:
• Copy: Ctrl + B then [, navigate to the text, press Enter to copy.
• Paste: Ctrl + B then ].

• Vite: Vite comes with a simpler configuration out of the box. It’s opinionated, meaning it has built-in best practices and defaults, making it easier to get started with.
• Webpack: Webpack is highly configurable and can be customized extensively, but this flexibility often comes with a steeper learning curve and more complex configuration files.

• Vite: Vite handles modern JavaScript features natively, leveraging the browser’s capabilities during development and optimizing for production only when needed.
• Webpack: Webpack can bundle any kind of asset (JavaScript, CSS, images, etc.) and provides advanced features like code splitting, tree shaking, and asset management, but these can add complexity to the build process.

First, create a new directory for your project and initialize it with npm:

   mkdir graphql-server
   cd graphql-server
   npm init -y

import React from 'react';
import useFetch from './useFetch'; // Ensure correct import path

function UserList() {
    const { data, loading, error } = useFetch('https://jsonplaceholder.typicode.com/users');

    if (loading) return <p>Loading...</p>;
    if (error) return <p>Error: {error.message}</p>;

    return (
        <ul>
            {data.map(user => (
                <li key={user.id}>{user.name}</li>
            ))}
        </ul>
    );
}

export default UserList;

• Reusability: The useFetch hook can be used across different components and applications, reducing code duplication and simplifying API interaction.
• Loading and Error States: Automatically manages loading and error states, providing a consistent way to handle asynchronous operations.
• Cleanup Handling: Prevents state updates on unmounted components, reducing potential memory leaks and ensuring stability.

}

• Animation Integration: Add animator components and trigger animations based on movement and jump states.
• Advanced Physics: Integrate more complex physics interactions, such as slopes or surface friction.
• Networking: Adapt the controller for multiplayer environments using Unity’s networking solutions.
