# Offline Node.js 22 setup for Ubuntu 20.04

This folder contains scripts to prepare and install fresh Node.js 22 without internet on target host.

## Files

- `prepare-online.sh` - run on internet-connected Linux machine
- `install-offline.sh` - run on offline Ubuntu 20.04 machine

## 1) On online machine

```bash
cd nodejs-offline-ubuntu2004
chmod +x prepare-online.sh install-offline.sh

# x64, latest v22
./prepare-online.sh x64

# OR arm64, latest v22
./prepare-online.sh arm64

# Optional: pin exact version
./prepare-online.sh x64 22.15.0
