NVM - Node.js Version Manager
When maintaining Angular apps and other Javascript-based libraries, you will come across the need to have a specific version of Node.js running on your development host.
Node Version Manager, is a Windows based package, that will swap in desired versions of Node.js as needed.
NOTE: If you are installing NVM and Node on a Jenkins server, you will need to run all of the following under the jenkins user context.
See this page for how to impersonate the Jenkins user: https://wiki.galaxydump.com/link/111
As a quick answer, run this to become the Jenkins user, for the purpose of the steps in this article: sudo su jenkins
And, be sure to exit from the jenkins user context, when finished.
Installing NVM
For Windows
Download and install the latest version of nvm for Windows.
For Ubuntu
Run the following:
curl -fsSL https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.5/install.sh | bashThen, add the following to your shell profile (~/.bashrc, ~/.profile, or ~/.bash_profile):
export NVM_DIR="$HOME/.nvm"
[ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh"Apply Changes:
source ~/.bashrcVerify NVM is installed:
nvm --versionOnce confirmed installed, you can install the desired Node.js versions that NVM will manage for you.
Usage
Installing Versions
Once installed, you need to tell NVM to install the desired Node.js versions that it will manage for you:
nvm install 16
nvm install 20
Switching Versions
With the desired versions of Node.js installed, you can use these commands to switch between them:
To run Node.js v16 (for Angular v14):
nvm use 16.20.2
To run Node.js v20 (for Angular v17):
nvm use 20.18.3
NOTE: Each time you tell NVM to switch versions, it may require answering a UAC popup.
Verifying Active Version
And once NVM has switched in the desired Node.js version, you can call this, to verify:
node -v
Listing Installed Versions
Use this command to see what versions of Node.js are installed and managed by NVM:
nvm list
