tresoneur / caerostris

A Spotify client for the web, written in C# with Blazor.

Cærostris

Demo

The latest version of Cærostris can be accessed here. Cærostris should be viewed in desktop browsers and on screens at least 1600 pixels wide.

Status of this project

This project is currently under development.

The goal of this project

To create a proof-of-concept Blazor WebAssembly PWA Spotify client with .NET languages and tooling.

How to build

• Get the latest .NET SDK (and the latest Visual Studio 2019 Preview)

• Get SpotifyService. You can either place SpotifyService where Caerostris.sln and Caerostris.csproj expect it to be or you can edit the path in the following locations:

  Project("{...}") = "SpotifyService", "..\SpotifyService\SpotifyService.csproj", "{...}"
  EndProject
  

  <ItemGroup>
      <ProjectReference Include="..\SpotifyService\SpotifyService.csproj" />
  </ItemGroup>

• Get a DevExpress Blazor (free (as in beer)) license and use VS or dotnet nuget add source to supply the resulting nuget source.

• Run dotnet build.

Design considerations

• Cærostris uses SCSS. Each razor folder contains a Styles folder with at least one .scss file, which are included in /Styles/Site.scss along with other .scss files in the /Styles folder that do not belong to any one particular component.

• Cærostris is a Progressive Web App.

caerostris's Issues

Janky virtual scrolling in datagrids

Virtual scrolling in DevExpress DxDataGrid components feels janky regardless of the amount of data loaded, suggesting a mistake in their implementation.

Datagrids crash when sorted in descending order

But only when built with the Release config. I'm inclined to believe that this one is not on DevExpress, but I can't reproduce it in a clean project.

Your AV software detects and blocks several dlls when loading the site

You shouldn't MITM your own TLS connections.
Also, Blazor WebAssembly will soon support ahead of time (AoT) compilation, but until then, Blazor WA apps run in interpreted mode with of a WA Mono runtime.

Can't click on tooltips that appear near the top of a chart

The DevExpress DxChart implementation simply doesn't take it into account that a user should be able to click on a tooltip.

Pie chart resets its state when a tooltip is clicked

The DevExpress DxChart implementation simply doesn't take it into account that a tooltip might be clicked. A fix for the content of tooltip persisting after its background disappears has already been incorporated into Caerostris.

Playback started in the Library shouldn't end after just a few songs

The Spotify Web API doesn't support starting a playback with the user's saved tracks as a context. DxDataGrid doesn't have support for retrieving the filtered and sorted data.
Result: a hack is used to gather the tracks visible to the user. DxDataGrid doesn't honor the page size property in virtual scrolling mode, so no more than 25 tracks can be known to Caerostris at a time, unless I were willing to use the interface of DxDataGrid to retrieve the sorting and filtering rules, which I am not, because writing my own datagrid would take considerably less time.
