Running the Azurite Emulator as a Windows Service with NSSM - a self-contained script

You can use the following script to install NSSM and Azurite, as well as install Azurite as windows service. Of course, after some adjustments, it can also be used to run any powershell script snippet as windows service.

Usage:

To install NSSM from Chocolatey and Azurite from NPM, use script.ps1 install-dependencies
To install Azurite as Service, use script.ps1 install
To uninstall the service, use script.ps1 uninstall

# Can be used to run the Azurite Emulator as a Windows Service via NSSM
# Make sure to have NSSM installed (e.g. via "choco install nssm")
# Also make sure to have Azurite installed ("npm install -g azurite")
# You can also use the "install-dependencies" command
