a11y.1 is the audit's last Critical and reproduced exactly: seven config-section headers, seven bare `<div @click>`s with no tabindex, no role and no aria-expanded, and every section collapsed by default — so every setting in the app was behind a control that could not be tabbed to. a11y.2 is the same bug in Downloads' two `<div class=tab>`s. Both now follow patterns the app already had: a real `<button aria-expanded aria-controls>` (explore-artist-details has five), and a role=tablist/tab/tabpanel with a roving tab stop and Left/Right/Home/End. The section body renders unconditionally and is toggled with `hidden`, because aria-controls has to name an element that exists and the slot's light-DOM children exist either way. H-22's reorder ships with them: Libraries is first and the only expanded section, Search Index — configured once, if ever — is second to last. The Playback/Audio section H-22 also asks for is deliberately not here: there is no output-device, gapless, crossfade or replay-gain setting in backend/config to expose, and a section of controls that do nothing is worse than admitting it does not exist. Settings also stops advertising `tracklist.delete`, which was bound to Delete and configurable in the UI while nothing listened for the event it dispatched.
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.
vitefor- transpiling typescript
- bundling the final "package" that is useb by the webview
- running a dev server with hot-reloading
- configured with the
vite.config.tsfile in this directory
pnpmfor managing frontend dependency packages
There are a handful of dependency packages that we use directly in the frontend.
picocssfor basic CSS while developinglitfor a simple but powerful wrapper around Web Components
Lastly, there are some dependencies that only benefit development
tsservercomes bundled with vscode and can be used as an LSP with other editors usingtypescript-language-server- Used for autocomplete, syntax highlighting, etc.
- This can be configured with the
tsconfig.jsonfile in the root of the project- NOTE: your configuration should align with the
viteconfig 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.
