Set up Node.js

 

Set up Node.js. On Apple Silicon, the setup is almost the same as Intel, but some tools need ARM64 builds. I'll give you the main methods step by step:

✅ Method 1: Install Node.js with Homebrew (simple & recommended)

  1. Install Homebrew (if not already installed):

    /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"

  2. Install Node.js (includes npm):

    brew install node

  3. Verify installation:

    node -v
npm -v

    You should see versions (e.g., v22.x.x for Node and 10.x.x for npm).

✅ Method 2: Install Node.js using Node Version Manager (nvm) (best for multiple versions)

👉 Recommended if you work on different projects needing different Node versions.

  1. Install nvm:

    curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.7/install.sh | bash

  2. Load nvm (add this to your ~/.zshrc or ~/.bashrc):

    export NVM_DIR="$HOME/.nvm"
[ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh"

  3. Restart terminal, then check:

    nvm --version

  4. Install latest Node.js:

    nvm install node

  5. Install specific version (example: LTS v20):

    nvm install 20
nvm use 20

  6. Check version:

    node -v
npm -v

✅ Method 3: Install via official Node.js installer (GUI)

  1. Go to Node.js Downloads.

  2. Choose macOS Installer (.pkg) ARM64 for Apple Silicon.

  3. Run installer → follow prompts.

  4. Verify:

    node -v
npm -v

⚡ Pro Tip

  • If you’re going to do a lot of development → use nvm (method 2).

  • If you just need Node quickly for one project → use Homebrew (method 1).

  • If you prefer GUI → official installer (method 3).
