Switch between node versions on Windows

By default, you have 1 node.js and NPM version installed on your machine. However, if you have to maintain applications written in multiple Angular and/or Typescript versions, this can become a problem. Older Angular/Typescript applications are not compatible with the latest node.js version and can no longer be compiled.

In Linux, this has been solved by the introduction of nvm , the node version manager. With it, it is possible to quickly install(and uninstall) different node.js versions and easily switch between them via the command line.

NVM-Windows

With nvm-windows, an alternative is also available for Windows. You can easily install nvm-windows on your local machine via the installer available here: https://github.com/coreybutler/nvm-windows/releases .

Using nvm-windows is very simple:

  • Install a node.js version:
    nvm install <version>
  • Listing the installed versions:
    nvm list
  • Switching between versions:
    nvm use <version>

Note: Global packages(if used) must be installed per node.js version.

Using NVM-Windows on your build server

NVM-Windows is not only useful on your local dev machine but can be a big help on your build server as well. Install nvm-windows on your build server after which you can invoke it in your YAML templates:

# ASP.NET Core (.NET Framework)
# Build and test ASP.NET Core projects targeting the full .NET Framework.
# Add steps that publish symbols, save build artifacts, and more:
# https://docs.microsoft.com/azure/devops/pipelines/languages/dotnet-core
trigger:
- master
pool:
name: 'default'
variables:
solution: '**/example/*.sln'
buildPlatform: 'Any CPU'
buildConfiguration: 'Development'
artifactName: 'Example'
steps:
- task: PowerShell@2
displayName: 'nvm use 16.14.0'
inputs:
targetType: 'inline'
script: |
nvm install 16.14.0;
nvm use 16.14.0;
view raw build.yml hosted with ❤ by GitHub

Keep in mind that changing the node.js version is a global change that impacts all build agents.

So also remember to always reset the node.js version to the latest version in your build pipeline.

Kubernetes–Limit your environmental impact

Reducing the carbon footprint and CO2 emission of our (cloud) workloads, is a responsibility of all of us. If you are running a Kubernetes cluster, have a look at Kube-Green . kube-green is a simple Kubernetes operator that automatically shuts down (some of) your pods when you don't need them. A single pod produces about 11 Kg CO2eq per year( here the calculation). Reason enough to give it a try! Installing kube-green in your cluster The easiest way to install the operator in your cluster is through kubectl. We first need to install a cert-manager: kubectl apply -f https://github.com/cert-manager/cert-manager/releases/download/v1.14.5/cert-manager.yaml Remark: Wait a minute before you continue as it can take some time before the cert-manager is up & running inside your cluster. Now we can install the kube-green operator: kubectl apply -f https://github.com/kube-green/kube-green/releases/latest/download/kube-green.yaml Now in the namespace where we want t...
