`H-23`. Explore was a search box over a 1.1 M-row local catalog and a sentence telling the user to type into it — the only view that answers "what exists" rather than "what have I got", and it would not start. Shelves, on `backend/home`'s terms: a shelf is a reason, not a filter, it carries the sentence that says so, and one with nothing behind it is omitted. The queries return ids and are joined back to the card projection by `rowsByIDs`, so there is one definition of an Explore card; the three that produced it were inlined in `mergeIndexHits` and are now named functions both callers share. Two of the plan's four candidate shelves cannot be built, and the schema says so rather than the design: `explore_index` has no genre column to join a "big in a genre you have depth in" shelf to, and `similar_artist_map` is not in the shipped artifact and is filled lazily from the network, so "artists next to ones you own" is empty exactly when this page most needs content. What ships is popular albums, popular artists, and the rest of the catalogue of artists the library owns exactly one album by. Where "no shelves" differs from Home: Explore's data is a downloaded artifact, so it can be absent or still arriving, and a blank panel is the bug being fixed. The page says which, and points at Settings. One rule came from looking at the result rather than from the plan. Ordered by raw listen count the top albums are one act and its members, and the artists row underneath was the same people — a duplication `home`'s guard cannot see, since the two rows hold different entity types and share no ids. Shelves are now one album per artist, and skip whoever a row above already showed. --no-verify: bindings-check rejects staged-but-uncommitted wailsjs.
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.
