continuous-integration/drone/push Build is passing
Phase 5b and Phase 6: TypeScript restructure, jsdom tests, regex filters and per-playlist buffer in the UI
TypeScript:
- menu_ts.ts split into menu.ts, content.ts, popup.ts and xmltv.ts; the
  other files drop their _ts suffix. Bundle order fixed in ts/tsconfig.json.
- All 94 string event handlers (setAttribute("onclick", "javascript: ..."))
  replaced with addEventListener closures. changeButtonAction, which
  rewrote an onclick attribute from select values, is gone.
- Settings rows are generated from one SETTINGS_FIELDS table instead of
  ~20 copy-pasted blocks; rendered HTML is byte-identical to before.
  saveSettings now serialises password inputs, so a changed Plex token is
  actually sent (the server treats the mask as unchanged).
- createLayout rebuilds the menu list only when the set of visible items
  changes, so focus in the menu survives a refresh.
- announce()/alertUser(): alerts are mirrored into an aria-live region.
- Filter popup offers a third type, Regular Expression (regex-filter), and
  the filter table labels it. Playlist popups get a Buffer select
  (default / none / xTeVe / FFmpeg / VLC) saved as the playlist's
  "buffer" parameter; the tuner field stays editable when the
  playlist's own buffer is active.

Tests: tests/ holds 27 jsdom tests (Node's built-in runner, jsdom pinned)
that load the built bundle with a fixture server payload: menu visibility
rules, mapping table renders names as text, settings panel fields, popup
flows, sorting, bulk select, layout refresh keeps nodes, live region,
regex option, buffer select. npm test runs in the Drone webui-check step.
README-DEV documents the layout and the test workflow.

Developer notes

Layout

Path What it is
xteve.go main: flags, version, start-up
src/ the application (one Go package src)
src/internal/ authentication, image cache, M3U parser
html/ web interface: HTML pages, CSS, images, the compiled js/app.js, and embed.go which embeds the lot
ts/ TypeScript sources for the web interface
docker/ container entrypoint
tasks/ improvement plan and checklist

Build the binary

Go 1.27.1 is pinned in go.mod; the go command downloads it automatically.

go build ./...
go vet ./...
go test ./...

The web interface is embedded with go:embed from html/, so a bare clone builds a complete binary.

Web interface

The UI is plain TypeScript compiled as global scripts (no modules yet) into a single bundle, html/js/app.js, which is committed. CI rebuilds it and fails if the committed file is stale.

npm ci          # installs the pinned TypeScript compiler and jsdom
npm run build   # ts/*.ts -> html/js/app.js
npm run check   # type-check only
npm test        # jsdom tests under tests/ (Node's built-in runner)

File order in the bundle is fixed in ts/tsconfig.json: network, menu, content, popup, xmltv, settings, logs, base, configuration, authentication. Classes must be defined before the top-level statements in later files that instantiate them. All pages load the same bundle.

The tests load the built bundle into a jsdom window (tests/harness.js) with a fixture server payload (tests/fixture.js), so they exercise the real rendering code. Run npm run build before npm test.

English strings are inlined in the TypeScript. There is no language layer.

Run from source

go run . -config /path/to/config -port 34400

Add -dev to serve the web interface from the local html/ directory instead of the embedded copy, so CSS and HTML edits show up on reload. JavaScript still needs npm run build.

Versioning and release

The version lives in two places that must agree: var Version in xteve.go and the first #### heading in changelog-beta.md (without the -beta suffix). CI fails on drift.

Drone (.drone.yml) runs vet, tests, the bundle check, hadolint and compose validation on every push. Pushes to master publish registry.coadcorp.com/nathan/xteve:latest and :<sha>; other branches publish :<branch> and :<sha>.

Endpoints useful for operations

  • GET /healthz returns {"status":"ok","version":...,"scanInProgress":...} with no authentication. The Docker healthcheck uses it.

Container image

Dockerfile builds the binary in a golang:1.27.1-alpine stage, copies static ffmpeg/ffprobe from a pinned mwader/static-ffmpeg tag (bump the tag in the Dockerfile; there is no other place to change) and runs on alpine. The runtime stage installs su-exec and does not set USER: docker/entrypoint.sh starts as root, applies PUID/PGID to the xteve user by editing /etc/passwd and /etc/group, fixes ownership of the config directory, and execs su-exec xteve:xteve xteve. With --user it skips all of that. ARG XTEVE_UID/XTEVE_GID remain the build-time defaults so Drone's build args still work. Check the script with sh -n and shellcheck -s sh after editing.
