yonlu 963269b753 feat: artist image disk cache + fix top results artist photos
Two changes:

1. Artist image disk cache: ArtistImageProvider now fetches the
   actual image bytes from Wikimedia Commons and caches them on
   disk (~/.local/share/yellowjacket/artist-image-cache/{mbid}.jpg).
   Returns base64 data URLs, same pattern as CoverArtProxy.
   First lookup: resolve URL via MB/Wikidata + fetch image (~2s).
   Subsequent: instant from disk cache.
   404s cached as empty files to avoid re-fetching.

2. Top results artist photos: the Top Results section now shows
   artist images from the artistImageCache, same as the Artists
   section. Also shows englishName in the top card display name.

YellowJacket Frontend

This directory contains the frontend for YellowJacket.

Dependencies

There are a couple of tools that are required to build and use the frontend.

  • vite for
    • transpiling typescript
    • bundling the final "package" that is useb by the webview
    • running a dev server with hot-reloading
    • configured with the vite.config.ts file in this directory
  • pnpm for managing frontend dependency packages

There are a handful of dependency packages that we use directly in the frontend.

Lastly, there are some dependencies that only benefit development

  • tsserver comes bundled with vscode and can be used as an LSP with other editors using typescript-language-server
    • Used for autocomplete, syntax highlighting, etc.
    • This can be configured with the tsconfig.json file in the root of the project
      • NOTE: your configuration should align with the vite config so you get in-editor feedback that aligns with how the build will be done.

Development

Ideally, you would use the frontend in the wails app as the frontend depends on the Go bindings generated by Wails. You can do this by running wails dev in the root of the YellowJacket repo.

If you want to run the frontend standalone, make sure the Wails go bindings have been generated with wails generate modules. Then, you can run pnpm dev to run the vite dev server. For more information on what commands are available, refer to package.json.

Code

Web Components

Our frontend is based off of Web Components, a standard that provides native browser encapsulation of components that can include HTML, CSS and Javascript all together. Instead of writing these components manually in Javascript, we utilize lit as a wrapper library.

Typescript

To better integrate with our tooling and to provide a better developer experience with strong typing, we have written all functional frontend code in Typescript. Vite serves as our Typescript transpiler.

Important Files and Directories

NOTE: most of these directories have aliases defined in tsconfig.json and vite.config.ts so that we may refer to them by shorthand when importing.

  • index.html and index.js is the entrypoint for the frontend. The first page that loads.
  • wailsjs/go Go code bindings generated by wails reside here
  • wailsjs/runtime the Wails runtime code needed to use Wails features
  • src all app code resides here
  • src/assets static assets like fonts, images and icons
  • src/components lit components that are used to compose the application
  • src/pages pages that serve as other entrypoints for the application that can be navigated to
