Installation

Choose one of the following methods:

1. Using curl

curl -so- https://raw.githubusercontent.com/Watchdog0x/nva/main/install.sh | sudo bash

2. Using wget

wget -qO- https://raw.githubusercontent.com/Watchdog0x/nva/main/install.sh | sudo bash

Usage

First-time setup

After installation, run:

sudo nva -i 20.16.0 -s 20.16.0 -l

Output:

Node.js version 20.16.0 downloaded successfully to /opt/nva/nodejs
Node.js version 20.16.0 extracted successfully
Node.js version 20.16.0 has been set successfully.
Available Node.js versions installed on your system:
* Node.js 20.16.0 (Running)

Note

Use -i to install, -s to set the Node.js version, and -l to list installed versions.

Important

The global installation path for npm packages (npm install -g) is /usr/local. Ensure users have necessary permissions or run npm commands with elevated privileges.

Command syntax

nva [OPTIONS]

Options:

• -i, --install: Install a specific Node.js version
• -l, --list: List available Node.js versions on your system
• -s, --set: Set the active Node.js version
• -r, --remove: Remove an installed Node.js version
• -p, --patch: Update all installed Node.js versions to the latest
  • Subcommand clean removes old versions
• -v, --version: Print the version of NVA
• -h, --help: Display the help message

Automatic Updates

Set up a cron job for automatic updates:

1. Open the crontab editor:

   sudo crontab -e

2. Add a daily update job (runs at midnight):

   0 0 * * * /path/to/nva-script/nva -p >> /var/log/nva-update.log 2>&1

Note

When using sudo crontab -e, you can add the clean option for automatic cleanup. Use responsibly with appropriate permissions.

Uninstallation

Choose one of the following methods:

1. Using curl

curl -so- https://raw.githubusercontent.com/Watchdog0x/nva/main/uninstall.sh | sudo bash

2. Using wget

wget -qO- https://raw.githubusercontent.com/Watchdog0x/nva/main/uninstall.sh | sudo bash

3. Local uninstall

sudo bash /opt/nva/uninstall.sh
