Installing Node

Step-by-step guide to install Node.js using NVM, the tool that lets you manage multiple Node versions on the same machine.

Requirements

Operating System	Version
Debian	10

Installing NVM

Optional: clean up any previous NVM installation and cached folders.
```
rm -rf $NVM_DIR ~/.npm ~/.bower
```
Download and install the latest release from the project page at https://github.com/nvm-sh/nvm. Replace v0.35.3 with the current tag if it has changed.
```
curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.35.3/install.sh | bash
```
Reload your shell configuration so the nvm command becomes available.
```
source ~/.bashrc
```
Confirm that the installation worked.
```
nvm --version
```
```
0.35.3
```

Installing Node

Check the LTS version available at https://nodejs.org or run nvm ls-remote --lts, then replace 12.17.0 with the release you want to install.

nvm install 12.17.0

When the download completes, verify that Node is ready to use.

node --version

v12.17.0

Updating NPM

NPM ships with Node.js, but the CLI evolves quickly, so it's worth updating it after you install Node.

Install the latest stable release.

npm install -g npm@latest

Check the version.

npm --version

6.14.5

Installing Packages

The following command scaffolds a package.json file that tracks a project's dependencies.

npm init

Local install (updates package.json).

npm install --save express

npm install --save-dev eslint

Global install.

npm install -g @angular/cli
