A card grid has to know how much of an album is here — an album held 2 tracks of 10 wearing the same green tick as one held whole is the complaint the badge-accuracy work was filed about — and `GetAlbumCompleteness` is one query per album, which is fifty round trips for a grid of fifty. `GetAlbumsCompleteness` is the same question over a slice. It is two grouping levels rather than the single-album form's correlated subqueries, because a correlated subquery in the FROM clause is not something SQLite will reliably do, and because the slice may only be spelled once or sqlc expands it twice with independently numbered placeholders. An album with no files is absent from the result rather than zeroed: "I have none of this" and "I have no idea" are the third state `Known` exists to keep apart. The test that matters is that the two spellings never disagree — they are genuinely different SQL, so the risk is a drift in meaning (a disc's total counted once per file, a duplicate counted twice) rather than a typo.
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.
