# Node Operations

Install Node.js in Ubuntu-based containers.

## Operations

### Node.Install

Install Node.js globally in the container. Skips installation if already present (for warm containers). Calling this method disables automatic Node.js installation for subsequent npm operations. *Note: Npm operations (Ci, Install, Run, Test, Build) automatically install Node.js if not present.*

```csharp
Node.Install(); // Installs Node.js v22 (current LTS)
Node.Install("20"); // Installs Node.js v20
```

## Overview

The Node operations allow you to install Node.js globally in Ubuntu-based containers. This is useful when using the default `ubuntu:22.04` image, which doesn't include Node.js pre-installed.

For warm containers, the installation is skipped if Node.js is already installed at the correct major version, making subsequent builds fast.

## Example

Build a static website with Node.js.

```csharp
// Install Node.js (includes npm)
Node.Install();

// Install dependencies
Npm.Install();

// Build the site
Npm.Build();
```

## Version Support

You can specify the Node.js major version to install:

```csharp
// Install Node.js 20 (previous LTS)
Node.Install("20");

// Install Node.js 22 (current LTS, default)
Node.Install("22");

// Or use default (currently v22)
Node.Install();
```
