# Node.js Setup

> Install Node.js 20.19.6 and pnpm on the VPS

## Install nvm

```bash theme={null}
curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.40.1/install.sh | bash
```

Load nvm into the current shell (or just open a new terminal session):

```bash theme={null}
export NVM_DIR="$HOME/.nvm"
[ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh"
```

## Install Node.js 20.19.6

```bash theme={null}
nvm install 20.19.6
nvm use 20.19.6
nvm alias default 20.19.6
```

<Check>
  Verify the version:

  ```bash theme={null}
    node -v   # v20.19.6
    npm -v
  ```
</Check>

## Install pnpm 10.27.0

```bash theme={null}
npm install -g pnpm@10.27.0
pnpm -v   # 10.27.0
```

<Note>
  All J-Optic, Jethings, and Code213 projects use pnpm as the package manager.
</Note>

<Warning>
  nvm installs Node per-user in `~/.nvm`. If PM2 runs under a different user (e.g. via systemd), make sure that user also has nvm set up, or reference the full Node binary path in `ecosystem.config.js`.
