ui

Overview ¶

Package ui exposes the admin observability web UI as an embedded filesystem so the admin server binary is fully self-contained.

Build pipeline (no copy step — vite writes straight into this package):

1. `npm run build` in ui/ (tsc -b && vite build) writes the bundle directly to server/ui/dist/ — ui/vite.config.ts sets outDir to ../server/ui/dist, so the //go:embed below picks it up as-is.
2. `go build ./cmd/admin-server` (from server/; or `go build ./server/cmd/admin-server` from the workspace root) produces a binary that serves the static UI at "/" without depending on anything on disk.

During development you run `npm run dev` in ui/ (Vite on :5173 with a proxy to :8080) and access the admin UI directly without going through the Go embed path. The embed path is for production binaries.

The built dist directory (index.html + hashed assets) is committed so the binary is self-contained and `go install …/admin-server` works without a Node toolchain. If a checkout somehow lacks dist, FS still embeds an empty filesystem and the server falls back to the placeholder index from PlaceholderHTML.
