# Dev

The `retrodeep dev` command spins up a local development server, allowing you to test and develop your project in an environment similar to Retrodeep's production servers.

## Usage

To start the development server for your project, you can run:

```bash
retrodeep dev
```

This command will serve the current directory on a local server. If you need to serve a different directory or specify a port, you can use the additional flags provided.

#### Specifying a Custom Directory

To start a development server with a custom directory path:

```bash
retrodeep dev --dir /path/to/your/project
```

#### Specifying a Custom Port

By default, `retrodeep dev` serves your application on port `3000`. To specify a different port, use the `-p` or `--port` option:

```bash
retrodeep dev --port 5000
```

This will start the development server on port `5000`.

### Interactive Development

While the `retrodeep dev` server is running, any changes made to your project files will automatically be reloaded in the development server, providing a real-time development experience.

### Available Options

* `-p, --port <port>` - Specify a custom port to listen on.
* `-d, --dir <dir_path>` - Specify a custom directory path for the server to serve.
* `-h, --help` - Display help information for the `dev` command.
