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.

Building from source
YellowJacket is built with Go and a Lit/TypeScript frontend, bridged by the Wails framework.
Prerequisites
| Tool | Version |
|---|---|
| Go | 1.25+ |
| Node.js | 22+ |
| pnpm | 10+ |
| Wails CLI | v3 — vendored, no install needed (go tool wails3) |
The Wails v3 CLI resolves from the tool block in go.mod, so there is nothing
to install globally; make setup fetches it with the rest of the tooling.
On Linux, install the system libraries Wails needs. v3 builds against GTK4 + WebKitGTK 6.0 by default:
sudo apt-get install libasound2-dev libgtk-4-dev libwebkitgtk-6.0-dev # Debian/Ubuntu
sudo pacman -S alsa-lib gtk4 webkitgtk-6.0 # Arch
A machine without webkitgtk-6.0 can still build with -tags gtk3 against the
older WebKit2GTK 4.1 stack, but that is an escape hatch, not what CI or a
release builds.
macOS and Windows need no extra system packages. Run go tool wails3 doctor to
check your environment.
Build
make setup # install tooling and git hooks
make dev # run with hot-reload
make build-prod # produce a release binary
