Decky

Decky is a focused Windows desktop client for viewing and editing boards from a Nextcloud Deck instance.

Current status

The repository currently contains:

• Decky.Core, a UI-independent Deck REST API client and domain foundation;
• Decky.ApiSpike, a read-only connection and compatibility probe;
• Decky.App, the initial WinUI 3 desktop shell;
• focused tests for API path discovery, required headers, update serialization, completion clearing, color preservation, and text contrast.

Development

Install the .NET 10 SDK and the Visual Studio WinUI application-development workload. Then run:

dotnet restore Decky.slnx
dotnet test tests/Decky.Core.Tests/Decky.Core.Tests.csproj
dotnet run --project src/Decky.ApiSpike/Decky.ApiSpike.csproj

The compatibility probe prompts for a Nextcloud app password without echoing or storing it. It starts with read-only board, stack, and card-list requests. On a disposable test board, its explicitly confirmed WRITE mode also verifies card color creation/preservation, setting and clearing completion, same-stack reorder, cross-stack movement, response verification, and cleanup.

The desktop app stores its JSON settings in %LOCALAPPDATA%\Decky\settings.json. The app password is stored separately in Windows Credential Locker and is never written to the JSON file.

Updates

Release builds will be distributed as a signed MSIX bundle through a stable Decky.appinstaller feed. Forgejo is the source and CI/release host; installed copies do not update with git pull.
