Remix is a framework that allows you to build modern web applications with ease. In this guide, we will walk you through the process of setting up a new Remix project, installing necessary dependencies, and creating a basic application with a simple form.

**Introduction**

Remix offers a powerful and flexible way to build web applications, leveraging the latest web technologies. It provides a straightforward setup process and integrates seamlessly with Vite, a modern front-end build tool. In this tutorial, you will learn how to create a new Remix project, configure it with Vite, and build a basic form handling example.

**Step-by-Step Guide**

**1. Create a New Remix Project**
 

- Open the directory where you want to create the project.
- In the address bar of that folder, type "cmd" and press Enter.
- A command prompt will appear. Run the following command:
```
npx create-remix@latest
```

- When prompted, provide your project name.
- Choose not to initialize a new git repository.
- Choose not to install dependencies with npm.
- Navigate to your project directory and open it in VS Code:

```
cd your-project-name
code .
```

**2. Install Dependencies**

- Open the terminal in VS Code and run the following commands:

```
npm install @remix-run/node @remix-run/react @remix-run/serve isbot@4 react react-dom
npm install -D @remix-run/dev vite
```

**3. Configure Vite**

- Open the vite.config.js file and paste the following code:

```
import { vitePlugin as remix } from "@remix-run/dev";
import { defineConfig } from "vite";

export default defineConfig({
  plugins: [remix()],
});
```

**4. Create the Root Component**

- Open the root.tsx file inside the app folder and paste the following code:

```
import {
  Links,
  Meta,
  Outlet,
  Scripts,
} from "@remix-run/react";

export default function App() {
  return (
    <html>
      <head>
        <link
          rel="icon"
          href="data:image/x-icon;base64,AA"
        />
        <Meta />
        <Links />
      </head>
      <body>
        <h1>Hello world!</h1>
        <Outlet />
        <Scripts />
      </body>
    </html>
  );
}
```

**5. Create the Index Route**

- Open the _index.tsx file located in the app/routes folder and paste the following code:

```
import type { MetaFunction } from "@remix-run/node";
import { useState } from "react";

export const meta: MetaFunction = () => {
  return [
    { title: "New Remix App" },
    { name: "description", content: "Welcome to Remix!" },
  ];
};

export default function Index() {
  const [inputValue, setInputValue] = useState('');

  const handleChange = (e) => {
    setInputValue(e.target.value);
  };

  const handleSubmit = (e) => {
    e.preventDefault();
    console.log('Submitted Value:', inputValue);
    setInputValue('');
  };

  return (
    <div>
      <h1>Home Page</h1>
      <form onSubmit={handleSubmit}>
        <label>
          Enter something: 
          <input type="text" value={inputValue} onChange={handleChange} required />
        </label>
        <button type="submit">Submit</button>
      </form>
    </div>
  );
}
```
**6. Build and Serve the Project**

- Open the terminal and run the following commands to build and serve your project:

```
npx remix vite:build
npx remix-serve build/server/index.js
```
**7. View Your Application**

- Open your browser and navigate to http://localhost:3000. You should see a page with a form where you can enter text and submit it.

**Conclusion**
By following these steps, you have successfully set up a new Remix project, configured it with Vite, and created a basic form handling example. This setup lays the foundation for building more complex applications with Remix. Continue exploring Remix’s features to enhance your application further.
