Welcome to the winget-cli-restsource repository

Building the client

Prerequisites

• Git Large File Storage (LFS)
• Visual Studio 2019
• The following workloads:
  • .NET desktop development
  • Azure development
  • ASP.NET and web development

Open src\WinGet.RestSource.sln in Visual Studio and build. We currently only build using the solution; command line methods of building a VS solution should work as well.

Running locally

The REST functions can be run locally, but to use winget with them, the functions must be run using HTTPS, this is pre-configured by the launchSettings.json file.

1. In the src\WinGet.RestSource.Functions directory, run generate_self_sign_cert.ps1 in PowerShell.
   • This will generate a test pfx and install it into the Root store.
   • It will automatically be used as the HTTPS cert during local execution, thanks to launchSettings.json
2. Create a CosmosDB database instance in Azure, using either the above instructions, or manually.
   • Navigate to the Keys section of your CosmosDB instance in the Azure portal to find your connection information.
   • If you've used the ARM templates as described above, your Database will be named WinGet and your Collection will be Manifests
3. Copy src\WinGet.RestSource.Functions\local.settings.template.json to local.settings.json and populate required fields from the above Keys section.
4. Run the WinGet.RestSource.Functions project locally in Visual Studio using F5.
5. Add it as a source in winget with: winget source add -n "winget-pkgs-restsource" -a https://localhost:7071/api/ -t "Microsoft.Rest"

Your commands to winget will now use your locally running REST instance as the primary source.

Running Tests

Running tests are a great way to ensure that functionality is preserved across major changes. You can run these tests in Visual Studio Test Explorer. In Visual Studio, run the tests from the menu with Test > Run All Tests

Unit Testing Prerequisites

• Install the Cosmos DB Emulator
• Copy the WinGet.RestSource.UnitTest\Test.runsettings.template.json template configuration to Test.runsettings.json
  • The defaults should work for your local Cosmos DB emulator instance. You can change the configuration to point to a Cosmos DB instance in Azure instead.
  • Alternatively, all of the test configuration properties can be set as environment variables. This is useful for overriding properties in an ADO build.

Integration Testing Prerequisites

• Install the winget client locally.
• Copy the WinGet.RestSource.IntegrationTest\Test.runsettings.template.json template configuration to Test.runsettings.json
  • Modify the RestSourceUrl property to point to a deployed rest source endpoint. You can use the below instructions to deploy a rest instance.
  • If the local winget client doesn't already have the source added, the integration tests can add it. To do so, change the AddRestSource property to true. Visual Studio must be running as admin in this case.
  • There is a test case that modifies the rest source. By default it's disabled, to run it the RunWriteTests setting must be set to true. The FunctionsHostKey setting must also be set since the add/update/delete endpoints all require function authorization. We recommend creating a new pipeline-specific host key for this purpose.

Automatically create a rest source

The Microsoft.WinGet.Source PowerShell module provides the New-WinGetSource cmdlet to simplify the creation of a Windows Package Manager rest source. This PowerShell cmdlet will initiate a connection to Azure if not currently connected. Validating that the connection is established with a specific Subscription (if specified). Generate the ARM Parameter files with specified values, then create Azure resources with the generated ARM Parameter files and the provided ARM Template files.

The New-WinGetSource PowerShell cmdlet makes use of the following input parameters. For more information on how to use this cmdlet, use the Get-Help New-WinGetSource -Full or visit the New-WinGetSource PowerShell Article in Docs.

Required	Parameter	Description
Yes	Name	A string of letters which will be prefixed to your newly created Azure resources.
Yes	ResourceGroup	The Resource Group that will be used to contain the Azure resources.
No	SubscriptionName	The name of the Azure Subscription that will be used to pay for the Azure resources.
No	Region	The Azure location where the Azure resources will be created. (Default: westus)
No	ParameterOutput	The folder location that contains new items will be created in.
No	RestSourcePath	Path to the compiled Rest API Zip file. (Default: .\RestAPI\CompiledFunctions.ps1)
No	ImplementationPerformance	specifies the performance of the resources to be created for the Windows Package Manager rest source. ["Demo", "Basic", "Enhanced"]
No	ShowConnectionInstructions	If specified, the instructions for connecting to the Windows Package Manager rest source. (Default: False)

[!Note] The PowerShell Module must be re-imported each time the PowerShell window is closed.

How to:

1. From the Administrative PowerShell window run the following:

PS C:\> New-WinGetSource -Name "contoso" -ResourceGroup "WinGetPrivateSource" -Region "westus" -ImplementationPerformance "Demo" -ShowConnectionInstructions

1. After the above has completed, copy and run the connection information provided for your newly created Windows Package Manager rest source to add it to your WinGet client.
