# Assets

> Learn how to extend or add additional functionality to Nova.

## Overview

Assets allow you to extend or add additional functionality to Nova without the overhead of cards or resource tools. For example, you may wish to override a custom error component to match your branding or intercept Inertia interactions and provide additional data to routes.

## Defining Assets

Assets may be generated using the `nova:asset` Artisan command. By default, all new assets will be placed in the `nova-components` directory of your application. When generating an asset using the `nova:asset` command, the asset name you pass to the command should follow the Composer `vendor/package` format:

```shell theme={null}
php artisan nova:asset acme/analytics
```

When generating an asset, Nova will prompt you to install the assets NPM dependencies, compile its dependencies, and update your application's `composer.json` file. All custom assets are registered with your application as a Composer ["path" repository](https://getcomposer.org/doc/05-repositories#path).

Nova assets include all of the scaffolding necessary to build your asset. Each asset even contains its own `composer.json` file and is ready to be shared with the world on GitHub or the source control provider of your choice.

## Registering Assets

Nova assets are automatically loaded through the use of Laravel's auto-loader, so no additional registration is required.

## Compiling Assets

Your Nova asset contains a `webpack.mix.js` file, which is generated when Nova creates your custom asset. You may build your custom asset using the NPM `dev` and `prod` commands:

```shell theme={null}
# Compile your assets for local development...
npm run dev

# Compile and minify your assets...
npm run prod
```

In addition, you may run the NPM `watch` command to auto-compile your assets when they are changed:

```shell theme={null}
npm run watch
```
