NodeJS | Setup environments

Working with multiple NodeJS Versions

If you plan to work with different NodeJS Version, we suggest to setup the following folder structure. Choose for #YOUR ROOT# whatever you want as your base folder, e.g. D:\Development

Install NodeJs Binary Package (.zip File)

Download and extract the NodeJS Binary Package to your destination folder:

Version32 Bit64 Bit
14.15.1https://nodejs.org/dist/v14.15.1/node-v14.15.1-win-x86.ziphttps://nodejs.org/dist/v14.15.1/node-v14.15.1-win-x64.zip
15.2.1https://nodejs.org/dist/v15.2.1/node-v15.2.1-win-x86.ziphttps://nodejs.org/dist/v15.2.1/node-v15.2.1-win-x64.zip

So, NodeJS 15.2.1 Files should be extracted to:

 #YOUR ROOT#\Environments\NodeJS\15.2.1\node

Kepp in mind: if you extract the zip file. it creates a folder with the name of the zipfile and extracts all files in this folder, e.g. node-v15.2.1-win-x86.

We wil call this installation folder HOME_NODE.

HOME_NODE = "D:\Development\Environments\NodeJS\15.2.1"

So, best practice is to extract the zip file in the NodeJS folder #YOUR ROOT#\Environments\NodeJS\15.2.1 ($HOME_NODE) and rename node-v15.2.1-win-x86 to node after extraction is complete.

Your finale folder structure should look like this:

Create start script

Create a start script to setup up environment variables and path:

Powershell

#
#
#
$NODE_VERSION              = "15.2.1"
$ENV:NODE_HOME             = "D:\Development\Environments\NodeJS\$NODE_VERSION"
$ENV:NPM_CONFIG_USERCONFIG = "$ENV:NODE_HOME\.npmrc"

$ENV:NPM_CONFIG_REGISTRY   = "http://localhost:4873"
$ENV:NPM_CONFIG_PREFIX     = "$ENV:NODE_HOME\npm"

$ENV:PATH="$ENV:NODE_HOME\node;$ENV:NODE_HOME\npm;$ENV:PATH;"

Write-Host "╔══════════════════════════════════════════════════════════════════════════════════════════════════════════════════════╗"
Write-Host "║                                       N O D E J S  ---  P L A Y G R O U N D                                          ║"
Write-Host "╚══════════════════════════════════════════════════════════════════════════════════════════════════════════════════════╝"

npm config set registry "$ENV:NPM_CONFIG_REGISTRY"

echo "HOME_NODE           = $ENV:NODE_HOME"
echo "NODE                = $((Get-Command node.exe).Path)"
echo "NPM_CONFIG_PREFIX   = $ENV:NPM_CONFIG_PREFIX"
echo "NPM_CONFIG_REGISTRY = $ENV:NPM_CONFIG_REGISTRY"

Create a Shortcut

Create a Shortcut for this file by dragging the powershell script (with pressed ALT key).

Rename the Shortcut, e.g. „Start NodeJS 15.2.1“

Edit the Shortcut properties

Right-Mouse-Click on Symbol and then select Properties:

Change Destination to:

C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe -noexit D:\Development\Environments\NodeJS\15.2.1\set_env.ps1

Explanation

Call the powershell program

C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe

With the parameter

 -noexit

And the parameter

D:\Development\Environments\NodeJS\15.2.1\set_env.ps1

Which means:

Call Poweshell to run the script set_env.ps1 and stay in Powershell after the Script is finished.

Configure with .npmrc

Create a configuraton file .npmrc in the folder $HOME_NODE (e.g. D:\Development\Environments\NodeJS\15.2.1) using your favourite editor.

notepad D:\Development\Environments\NodeJS\15.2.1\.npmrc

Add this line to the file:

cache=D:\Development\Environments\NodeJS\15.2.1\npm-cache

Save the file

Run the script

Double-Click on the shortcut

Tipps und Tricks

Install Build Tools

Some packages needs to build from source. These packages require additional tool, e.g. compiler.

Install all the required tools and configurations using Microsoft’s windows-build-tools using npm install --global --production windows-build-tools from an elevated PowerShell or CMD.exe (run as Administrator).

npm install --global --production windows-build-tools
