Every artist name in the app went through `artistLink(name, mbid)`, so a track credited to several artists rendered one link and the rest as punctuation — "2Pac feat. Snoop Dogg" linked 2Pac and left Snoop Dogg as text inside it. `creditLink(parts, fallbackName, fallbackMbid)` renders the credit from its parts: one link per credited artist, join phrases as plain text between them. The link boundaries are known by construction, which is the point — locating a name inside the stored credit string would reintroduce the mismatch the catalog exists to avoid, since that string may come from the file's tags while the parts come from MusicBrainz and the two disagree for ~1 in 3 multi-artist credits. Fewer than two parts falls through to the previous behaviour exactly, so a single-artist credit, a file with no recording MBID and a catalog that has not answered yet all render as they did before. Nothing tries to split the fallback string: "Simon & Garfunkel" is one artist, which is why primaryArtist() does not split on "&" either. The lookup is keyed on the recording MBID, which both sides already carry — a catalog row has one and so does a local file — so one binding serves Explore and the library's own lists, and no local table is needed for this. credit-store.ts, and three things in it are load-bearing: - A miss is cached as an empty array. The backend returns nothing for a single-artist credit, which is ~87% of tracks, and caching only the hits would re-request the rest on every render forever. - request() is per-row and coalesces into one call per frame. A virtualized list cannot hand over "the whole list": 50,000 rows would be 100 queries for the ~30 on screen. - It is an LRU with a counted retainedChars probe, because a cache that grows with use is a leak with a schedule. The virtualized lists push requestUpdate() into the virtualizer rather than only the host, since its rows come from its own properties — a host update alone would leave them exactly as they were. now-playing marks its geometry dirty instead, because the marquee measures the text it is about to scroll. track-list keeps the single link while a search term is active: the highlight spans are computed against the flat credit string, and mapping them onto decomposed parts is a different problem.

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.
- NOTE: your configuration should align with the
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.
