Developing PowerShell modules for REST APIs – Part2

This is part 2 of the REST API blogpost. In part1 we successfully setup two REST API endpoints using the UniversalDashboard PowerShell module. In this part we are going to create a simple module that support some CRUD operation against our API. As we are trying to keep things as simple as possible, we will not use any fancy framework (like Plaster) to build our module. We are also going to skip a very important step you should familiarize yourself with, Pester tests. Lets get to it.


The moduleWe will build a module called FilesAPI. The module folder will look like this:



In the functions folder I have already added the 2 helper functions from part 1, Get-AuthorizationHeader and ConvertTo-Base64. The other folders are just placeholders for important stuff like classes, private functions that you do not want to make available for the module consumer and tests for Pester tests. For such a small module that we are going to create, one could argue that it is much easier to just add the functi…

Developing PowerShell modules for REST APIs – Part1

Over the years I have developed different PowerShell modules for different web APIs. I thought it would be a good idea to write a 2 series post about how you could go about to do this. This will be a 2 part blog series where we will run through the entire process of building a module for a REST API. I will try my best to keep this as simple as possible and leave more advanced stuff for a follow up post if the interest is there.What you needDepending on your experience with source control and PowerShell in general, you might want to use GIT or some other software repro for the code. In addition we are going to create a test REST API using the splendid UniversalDashboard PowerShell module created by Adam Driscoll. It is available on the PowershellGallery. Other prerequisites are built-in to Powershell. I will assume that you will be following along using at least PowerShell version 5 or greater.
