Learning how to install Node.js on Debian is essential for developers, DevOps engineers, and anyone building modern JavaScript backends, APIs, real-time apps, microservices, serverless functions, or full-stack projects in 2025–2026. Node.js powers Express, NestJS, Next.js APIs, CLI tools, automation scripts, and the vast JavaScript ecosystem. Debian 10 (Buster) is still widely used in production and legacy servers, so this guide covers three proven methods to install Node.js:

  1. Default apt repositories — Quick & stable (v10.x or updated)
  2. NodeSource PPA — Latest LTS (v18/v20) or current versions (recommended for production)
  3. nvm (Node Version Manager) — Multiple versions side-by-side (best for developers)

You’ll also verify installation, test with a simple script, install npm, upgrade, and learn to uninstall cleanly.

Prerequisites

  • Debian 10 (Buster) server or desktop
  • Non-root user with sudo privileges (see Debian Initial Server Setup Guide)
  • Terminal access (SSH or local)
  • Internet connection

Method 1: Install Node.js on Debian 10 Using Default apt (Quick & Stable)

This uses Debian’s official repositories — ideal for basic testing or production stability.

  1. Update package index
				
					sudo apt update

2. Install Node.js

				
					sudo apt install nodejs -y

3. Verify version

				
					node -v

Typical output (Debian 10):

				
					v10.24.0

4. Install npm (package manager)

				
					sudo apt install npm -y
npm -v

Output example:

				
					6.14.18

You now have Node.js installed on Debian 10 via apt — ready for basic use.

Warning: Debian 10’s default Node.js (v10.x) is unsupported and unmaintained in 2025–2026. Use Method 2 or 3 for production.

Method 2: Install Latest Node.js on Debian 10 Using NodeSource PPA (Recommended)

NodeSource PPA provides modern LTS (v18/v20) or current versions — far better than Debian’s old v10.

  1. Install curl (if not present)
				
					sudo apt install curl -y

2. Add NodeSource PPA (choose version — 2025–2026 recommendations):

  • LTS: setup_20.x (Node 20 LTS – most stable)
  • LTS: setup_18.x (Node 18 LTS – widely used)
  • Current: setup_current

Example for Node 20 LTS:

				
					curl -fsSL https://deb.nodesource.com/setup_20.x | sudo -E bash -

3. Install Node.js

				
					sudo apt install nodejs -y

4. Verify

				
					node -v    # e.g., v20.17.0
npm -v     # e.g., 10.8.x

Success! You now have a modern, supported Node.js on Debian 10.

Method 3: Install Node.js on Debian 10 Using nvm (Best for Developers)

nvm lets you install and switch between any Node version instantly — perfect for legacy code, testing, or multiple projects.

  1. Install nvm
				
					curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.40.1/install.sh | bash

Close & reopen terminal (or run):

				
					source ~/.bashrc

2. Install latest LTS

				
					nvm install --lts
nvm use --lts
nvm alias default lts/*

Or specific version:

				
					nvm install 20
nvm use 20

3. Verify

				
					node -v
npm -v

Switch anytime:

				
					nvm install 18
nvm use 18
nvm ls                # list installed
nvm ls-remote         # all available versions

Step 4 – Test Your Node.js Installation

Create a test file:

				
					nano hello.js

Paste:

				
					console.log("Hello from Node.js on Debian 10!");
console.log("Node version:", process.version);
console.log("Platform:", process.platform);

Save & exit (Ctrl+O → Enter → Ctrl+X).

Run:

				
					node hello.js

Output example:

				
					Hello from Node.js on Debian 10!
Node version: v20.17.0
Platform: linux

Success!

Step 5 – Upgrade, Uninstall & Troubleshooting

Upgrade Node.js

  • Apt: sudo apt update && sudo apt upgrade nodejs
  • NodeSource: Re-run PPA setup → sudo apt upgrade nodejs
  • nvm: nvm install node –reinstall-packages-from=current

Uninstall Node.js

  • Apt: sudo apt remove –purge nodejs npm && sudo apt autoremove
  • nvm: nvm uninstall <version> (e.g., nvm uninstall 20)

Common Issues on Debian 10

  • E: Unable to locate package nodejs → Run sudo apt update first
  • npm permission errors → Fix global installs:
				
					mkdir ~/.npm-global
npm config set prefix '~/.npm-global'
export PATH=~/.npm-global/bin:$PATH

Add to ~/.bashrc and source ~/.bashrc.

  • Old Node version after install → Use NodeSource PPA or nvm for latest
