The app opened on Tracks — an alphabetical list of everything, which is the one entry point that is identical every time and therefore gives the user nothing to start from. Home is listed first in the nav and is the page built to answer 'what should I play' (H-8). Two things had to be true before that was an improvement. An album with no cover rendered as a small dim icon on a surface the same colour as the page, so a shelf read as having holes in it, while the Albums and Artists grids both drew a letter tile (H-9). It draws the same tile now. And a shelf that repeats the one above it is suppressed, the way an empty one already is — 'On repeat' was 'Pick up where you left off' reordered. The rule fires only when the shelf is not showing the whole library: a repeat is a fault only if a different row was possible, and measured against a fixed shelf size instead this let an 11-album library keep three identical shelves while a 13-album one lost them. The first two versions of that rule were wrong and the *existing* Go tests caught both — it collapsed a four-album library to a single shelf. Nine e2e specs assumed the app starts on Tracks and now navigate there, and one new spec freezes the landing itself. Home's page-header action is 'Shuffle suggestions': 'Shuffle' alone was two different controls with one accessible name, which only became reachable together once a cached Home was always in the tree.
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.
