Npm.Install(frontend);
```

### Npm.Ci

```csharp
var frontend = Directory("./frontend");
Npm.Ci(frontend);
```

### Npm.Run

Run an npm script from package.json. Automatically installs Node.js if not present.

```csharp
var frontend = Directory("./frontend");
Npm.Run(frontend, "build");
Npm.Run(frontend, "lint");
```

### Npm.Test

Run 'npm test'. Automatically installs Node.js if not present.

```csharp
var frontend = Directory("./frontend");
Npm.Test(frontend);
```

### Npm.Build

Run 'npm run build'. Automatically installs Node.js if not present.

```csharp
var frontend = Directory("./frontend");
Npm.Build(frontend);
```

## Example

Build a frontend application.

```csharp
// Create a directory reference
var frontend = Directory("./frontend");

// Install dependencies (prefer ci for reproducible builds)
Npm.Ci(frontend);

// Run linting
Npm.Run(frontend, "lint");

// Run tests
Npm.Test(frontend);

// Build for production
Npm.Build(frontend);
