Waters ChurchandClaude Fable 5 2f4c357bf5 Timers 1.4.2: ProPresenter digits no longer flick back a second
ProPresenter reports running timers as truncated whole seconds, and the
poller re-anchored the tiles' local count at the bottom of that second on
every 500 ms poll — so the displayed digit ran up to a second ahead and
got yanked back a step whenever a fresh poll sampled the next flip later
than the last one did. Tiles flickered ...12:33 → 12:34 → 12:33... about
once a second.

phase.js turns the quantized reports into one stable anchor per timer:
the only information in a poll is a FLIP (the report stepping one second
in the direction of travel), which dates the true boundary to the
midpoint of the two polls that straddle it. While reports stay consistent
with the anchor (±450 ms) the anchor holds, so tiles count along one
steady clock; a report the anchor can't explain (reset, seek, resume,
accumulated drift) re-anchors. Timers carry the anchor as a per-timer
asOf the client extrapolates from (optional in the provider contract,
documented in the guide); the client additionally refuses to tick a
running card backwards over sub-1.5 s jitter.

phase.selftest.js (66 checks) drives a simulated ProPresenter — truncated
reports, jittered polls — through the tracker and the client's render
math: digits never step backwards, dwells hold 1 s (the ~2 s zero-crossing
dwell is trunc's honest behavior), anchors stay within tolerance of the
true value, resets snap, pause/resume re-locks, 0.2% clock drift is
absorbed. Verified live against tools/pp-timers-mock.js: 78 s of 100 ms
DOM sampling across four running cards — every step ±1 in the card's own
direction, dwells 998–1002 ms, zero regressions; upstream kill/restart
still recovers.

ProdDash

A modular production dashboard for Waters Church. Any browser on the building network opens one page and composes its own dashboard out of modules — independent tiles that each show one aspect of a live service. Ships with the live ProdCom transcript, the ProPresenter Now / Next display, and a booth clock; new modules drop into modules/ without touching the shell (see docs/MODULE-GUIDE.md).

How it works

server.js (zero dependencies, just Node.js) does four things:

  1. Serves the dashboard shell (public/) and the admin page (/admin).
  2. Discovers modules in modules/ and serves each one's client at /modules/<id>/.
  3. Mounts each enabled module's server routes under /api/modules/<id>/ — that's where module servers follow ProdCom, poll ProPresenter, and stream live updates over SSE — one upstream connection per module, however many dashboards are open — so browsers never talk to production gear directly (no CORS, and API keys never leave the server).
  4. Stores server-wide module config and named layouts in a per-machine data directory outside the app folder, so updating ProdDash never loses them.

Each browser arranges its own tiles (add, drag, resize, remove, per-tile settings); the layout autosaves to that browser's localStorage. Named layouts can also be saved to the server and loaded from any other browser. Every module survives its upstream disappearing: tiles show a red status dot and a clear degraded state, then recover on their own.

Run it

macOS — the app

Open the disk image and drag ProdDash to Applications. That's the whole installation: the app carries the dashboard and its own Node runtime, so nothing else has to be installed and nothing can be missing. It lives in the menu bar, starts and stops the server, can open at login, and holds the permissions the modules need — the microphone the LTC listener reads, and local network access for ProdCom and ProPresenter. macOS grants those to the app that owns the process, so a server started any other way (over SSH, from a launchd job) simply doesn't have them, and an LTC input goes silently to zeroes.

Build the disk image from a checkout with launcher/macos/build.sh:

cd launcher/macos && ./build.sh --dmg

Anywhere else, or from a checkout

Requires Node.js 18 or newer.

node server.js

Or double-click Start ProdDash.command (macOS) / start.bat (Windows).

Then open the URL it prints — http://localhost:24500 on this machine, or the http://<this-machine's-IP>:24500 address from any other device on the network.

Configure

Server-wide module settings (ProdCom URL, ProPresenter host, API keys, enable/disable) live in the admin page — open Admin from the dashboard's top bar, or go to /admin. Saving re-initialises the module immediately; open tiles reconnect on their own.

Where settings are kept

Everything you enter in the admin page (module connection settings, API keys, enabled/disabled flags) and every named layout is written to a data directory on the machine running the server — not into the app folder:

OS Data directory
Windows %APPDATA%\ProdDash (e.g. C:\Users\<you>\AppData\Roaming\ProdDash)
macOS ~/Library/Application Support/ProdDash
Linux $XDG_CONFIG_HOME/proddash, else ~/.config/proddash

Because it lives outside the checkout, you can git pull, re-clone, or reset the app folder from main and start the new version with everything still configured. The admin page shows the exact path in use, and the server prints it at startup (Settings : …).

The directory holds modules.json (module config), layouts/ (named layouts) and modules/ (modules installed from the admin page), all written by the app itself. Installed from the macOS app, it also holds app/ — the copy of ProdDash that actually runs, laid down from inside the app bundle on first launch and updated in place from then on (nothing may write inside a signed .app, and ProdDash updates itself). It may also hold a proddash.json with this machine's shell settings — the same keys as the checked-in config/proddash.json, which supplies the defaults:

Key Meaning
port Port ProdDash serves on (default 24500). The macOS launcher writes this one, so the port it is set to holds however ProdDash is started.
adminPin The admin PIN, as a scrypt hash. Set it in the admin page's Admin PIN section, not by hand — 6 digits, and only the hash is stored. Absent means admin is open to anyone on the network.
adminPasscode An older free-text passcode. Still honoured, so an existing install keeps working; new installs should use adminPin.
forge Where updates and module installs are fetched from. Absent or "github" uses GitHub; a Gitea or Forgejo base URL such as "http://10.3.8.90:3000" uses a server of your own. Set it per machine in the data directory, alongside repo.
theme The dashboard palette: booth (default), harbor, graphite, ember, daylight, midnight, moss, plum, sepia, blackout, paper or iron. The admin page's Theme section writes this one — see Themes.

Locked out? Delete adminPin from the data directory's proddash.json and restart, or start the server with PRODDASH_PASSCODE set — that passcode overrides the PIN and always gets you in.

Only /admin and the admin API are behind the PIN. Dashboards stay open, so a wall display needs no PIN, and it is unrelated to a module's own PIN (Slack's 4–8 digit send PIN, say), which guards that module's actions only.

Updating from your own git server. ProdDash fetches one tar.gz of the branch — nothing else — so any Gitea or Forgejo works. Point forge at its base URL and repo at the owner/repo there:

{ "forge": "http://10.3.8.90:3000", "repo": "michael/ProdDash", "branch": "main" }

Gitea spells an archive URL differently from GitHub, which is the only thing that changes; the tarball itself is identical, commit hash included, so update detection and module installs behave exactly as before. Make the repository readable without signing in, or ProdDash cannot fetch it.

Environment variables override both files: PORT, PRODDASH_PASSCODE, and PRODDASH_FORGE, and PRODDASH_DATA_DIR to put the data directory somewhere else (a relative path is taken from the app folder; PRODDASH_DATA_DIR=config restores the old in-repo location). If the default directory can't be created, the server says so and falls back to the app's config/ folder.

Upgrading from an earlier version: the first start copies an existing config/modules.json and config/layouts/ from the app folder into the data directory, so nothing has to be re-entered. The old files are left in place and ignored from then on.

Themes

The whole dashboard — every tile, on every browser — draws with one palette, chosen in the admin page's Theme section and switched live: pick a swatch and open dashboards change without a reload. The section starts folded — a building picks its palette once — and holds twelve presets:

Booth the default dark, mint accent
Harbor deep navy, cyan
Graphite neutral charcoal, electric blue
Ember warm broadcast black, orange
Daylight a cool light palette, for a front-of-house desk in daytime
Midnight indigo night, violet
Moss forest floor, lime
Plum aubergine, purple
Sepia warm brown room, cool teal — Ember's arrangement reversed
Blackout true black, cyan, for a dark room where any glow carries
Paper the warm light one, indigo accent
Iron no colour of its own: a near-white accent, so the only hues on screen are a module's own and the red and amber that mean something

Each keeps the status colours apart — the accent is never near the danger red or the warning amber — and muted text readable in a dark booth. The choice is stored as theme in the data directory's proddash.json (table above), so it holds across restarts and updates; a browser remembers the last theme it saw and applies it before the server answers, so nothing flashes. Modules style with the shell's colour variables, which is why they follow; a colour set on a tile itself (a PCO Plan header colour, say) is deliberately kept.

Installing modules and updating

Everything below happens in the admin page; ProdDash talks to its git repository — michael/ProdDash on the church's own Gitea at chronicles-ab.waterschurch.org:3000, branch main. Change it with forge, repo and branch in proddash.json, or the PRODDASH_FORGE and PRODDASH_REPO variables (owner/repo#branch). It downloads one small archive of the branch, at most every few minutes, only while the admin page is open or for the update check below. Nothing is installed without someone clicking.

  • Available modules lists modules in the repo that aren't installed here. Install downloads the module into the data directory's modules/ and starts it right away — nothing is written into the app folder, and no restart is needed. Modules that ship with your copy of ProdDash are "bundled"; ones you installed are "installed"; if both exist, the newer version runs.
  • Uninstall on a module card removes an installed module's files. For a bundled module (its folder belongs to the app) it hides the module from every dashboard instead; it reappears under Available modules and can be brought back without downloading. Settings are kept either way.
  • Module updates: when the repo has a newer version of an installed module, its card shows Update to vX.
  • Version requirements: every module declares the ProdDash versions it needs ("proddash": ">=1.1.0" in its manifest). A module that needs a newer shell is listed but not loaded, and cannot be installed until ProdDash is updated.
  • ProdDash updates: the admin page checks the repo shortly after start and every six hours, and shows a banner when main has a newer version (or new commits). Update now brings the app folder up to date and restarts the server; dashboards reconnect on their own. A git checkout is updated with git pull --ff-only (only when it is on the repo branch with no local changes — otherwise the banner says why and you update with git). A plain folder (no .git) has the repo archive unpacked over it; files removed upstream are left behind but harmless. Settings and layouts are never touched — nothing inside the data directory is written, even on an install where that directory is the app's own config/. What changed opens the commit comparison on the forge.
  • If an update goes wrong: the download has to parse before anything is swapped in, so a truncated or mangled server.js is refused with the reason and the running copy is left exactly as it was. Past that, the copy being replaced is set aside as app.previous next to the app folder, and dropped once the new version has stayed up for ninety seconds — so that folder existing means "the last update has not proven itself yet". The macOS app watches for a version that will not stay up (four stops in two minutes) and puts the old one back by itself, once, with a notification. Running some other way, the way back is a rename: mv app.previous app.
  • Restarting: after an update the server exits with code 75 and starts its own replacement, which waits for the port to free up. If you supervise ProdDash with your own launcher, set PRODDASH_LAUNCHER=1 so the server just exits and your launcher restarts it on exit code 75. PRODDASH_NO_REMOTE_CHECK=1 turns off the periodic check (the admin page still checks when opened).

Using the dashboard

  • + — add any enabled module; multiple tiles of the same module are fine (e.g. two transcripts filtered to different channels).
  • Drag a tile by its title bar to move it; ✕ removes it.
  • Resize from any edge or bottom corner, the way a window resizes: nothing is drawn on a tile to mark the spots — the cursor over an edge is what says it can be dragged. An edge moves only itself, so the tile grows or shrinks into the space beside it while the opposite edge stays put, stopping at a neighbour or at the module's own minimum size. Two exceptions, both of which move a shared edge instead: with another tile directly below, the bottom edge trades rows between the two so the column keeps its total height; and where two tiles meet side by side, the seam between them trades width (macOS split-view style), showing itself only while you drag it.
  • Fullscreen (the ⛶ button) is a viewing mode: the menu bar hides (its green lip at the top-left brings it back, minus the Admin button), the occupied columns stretch to the full width, and every column runs to the bottom of the screen — the last tile in each column is stretched to end there. A short tile like the clock is never stretched into a ribbon: under another tile it slides to the bottom edge and the tile above grows into the gap; alone in its columns it stays as it is. Nothing is saved — the layout reverts when you leave fullscreen. A layout deeper than the screen keeps its normal row height and scrolls.
  • A tile's actions (menus, text size, clear…) live in its title bar.
  • Auto-hide bars (the button left of ⛶) folds every title bar away, for a windowed screen that should read like a wall display. A folded bar is not a gone bar: point at the tile's top edge and it slides back in over the content, where its buttons click and its width drags the tile exactly as before — so a dashboard can be arranged with every bar out of the way. The switch is off on a fresh dashboard and saves with the layout — including a named layout on the server, so a booth loads its screen with the bars already tucked away. Fullscreen folds every bar regardless, and the same hover brings one back there too.
  • The pin beside a tile's title keeps that tile's bar showing while auto-hide is on — for the one or two tiles whose controls are wanted at a glance. It turns the accent colour when it is on and saves with the layout. Fullscreen still folds a pinned bar with the rest.
  • The menu bar's own handle is the ProdDash name itself, wrapped in a translucent green pill at the left — click it to hide the bar; the slim green lip it leaves at the top-left edge brings the bar back. It stays at the left so it never sits on top of a tile's own tab.
  • The gear on a tile holds per-tile settings (filters, text size, display options) — these belong to this browser's layout, not the server.
  • The grid icon — save the current arrangement to the server under a name, load a named layout (it becomes a local copy — browsers are never linked), or reset this browser's dashboard. Loading says what it did — Loaded "FOH": 9 tiles, 2 not shown — Service, #ops aren't offered right now — with Undo in the message to get back the arrangement you had. A tile whose module or picker entry isn't offered at the moment keeps its place and shows nothing, then appears when it is; it is never replaced by the module's default tile. Saving over an existing name asks first, and the server keeps the copy it replaced: Restore previous in Admin → Saved layouts swaps it back (and swapping again undoes that). The menu's Grid Size stepper sets how many columns this browser cuts the board into — 8 to 24, 12 by default. Finer lets tiles be smaller so more fit across (a 4K wall), coarser suits a small screen read close up; row height follows, so tiles keep their shape and simply change size. Going coarser, a tile that no longer fits where it was moves to the first free spot rather than onto another tile. It saves with the layout, so a named layout comes back at the density it was arranged on.
  • Every tile has a status dot: green = live, amber = connecting, red = upstream unreachable (hover it for details). Tiles reconnect automatically.

Included modules

  • ProdCom — live transcript stream with in-place updates of in-progress speech, channel colors, per-tile channel visibility toggles and group presets, timestamps, text size, a top-down / bottom-up direction toggle and jump-to-latest in the title bar. Admin config: ProdCom server (host : port), API key. Tile settings: channel icons, direction and timestamps.

  • ProPresenter — what's live and what's next, with slide progress, driven by the shared propresenter-core client (ProPresenter 7/20). The + picker offers two tiles: Now / Next, the full card, and Now, the live item alone with the gradient filling the tile edge to edge — a wall panel that says one thing. Admin config: ProPresenter endpoint (host : port), password. Tile settings: a Show group of switches for the playlist name, live status, NOW and NEXT labels, slide count, progress bar, the next list and its item tags, plus tidy titles.

  • Timers — live ProPresenter timers (countdown, countdown-to-time, elapsed) and LTC timecode as auto-sized cards. The + picker lists every discovered timer (and the LTC card) as its own tile, or add "All timers" and pick a selection via the tile's "Timers ▾" menu; overruns are unmistakably red. Read-only — no start/stop controls. Admin config is in three groups: ProPresenter (endpoint host : port, API password), LTC Timecode (the listener switch, and — when it's on — the audio device and channel), and Display (Timer font — Default or Monospace, which keeps the digits from shifting as the numbers change).

    ProPresenter exposes no timecode over any API, so LTC is decoded from the audio signal, behind the admin LTC listener switch (off ⇒ no LTC tile in the picker at all). On, the module captures the selected audio input device/channel on the ProdDash machine — a native ltc-capture helper, compiled on first use — and decodes the SMPTE frames in-process: running/stopped/no-signal, the timecode counting frame-accurately in real time, and the frame rate (incl. 29.97 drop-frame). macOS note: the ProdDash server needs microphone permission — launch it from a logged-in session (Start ProdDash.command) and approve the one-time prompt; a server started over SSH or by bare launchd silently captures zeros. (Engine self-test: node modules/propresenter-timers/ltc.selftest.js.)

  • PCO Plan — Planning Center Services, as two tiles in the + picker: Plan (the order of service) and Teams (who is scheduled).

    Plan shows every plan item with its scheduled start time, length, type, song key, description and item notes. When the ProPresenter module is running it follows that module's live item, highlights the matching plan item, dims what's done and shows the elapsed vs planned runtime and how far ahead/behind the service is. Items are matched by name — a document named like the Planning Center item or its song, tags and all. The message is the exception: a sermon's document is named after the sermon, so a live document that reads like the plan itself — its date code, series title and part, as in 260927 Where is Your Faith? - Part 6 — is taken as the message and lands on the plan's message item (an item titled Message, Sermon or Teaching, else the first item under such a header). Admin config is the connection: Planning Center credentials (Personal Access Token app ID + secret, or an OAuth token), the service type (a list grouped by your Planning Center folders) and an optional pinned plan. Everything about the display is per tile (gear menu): the top-bar text (placeholders such as {series} • {part} | {serviceType} • {date}), colors, text size, and a show/hide checklist for every detail.

    Teams shows the same plan's team and position assignments — each team as a band of its people, with their photo (fetched through ProdDash, never by the browser; initials when Planning Center has none) and a dot for confirmed, unconfirmed or declined. Its gear menu picks which teams and which positions appear, groups people under their position or lists them plainly, and sets the colours: one for the team headers, or Tint teams to give each team its own, optionally carried into the rows. Teams nobody has signed up for are hidden until you ask for them — that list comes from the service type, since Planning Center only returns a team once somebody is on it.

  • Slack — live transcripts of this location's Slack channels, plus PIN-protected sending as the location. The + picker lists one transcript tile per configured channel, titled #channel, and two send surfaces (one of each per dashboard): Send message, a free-text box with the admin's quick emojis one press away, and Quick replies, a grid of preset buttons. Both post to the channel of whichever transcript was clicked last — its bottom edge lights up in the accent color — and to the first configured channel until one is clicked. Messages arrive with avatars, names and times, Slack's inline formatting and the workspace's custom emoji; a right-click on one opens the reaction menu, and text size and jump-to-latest sit in the title bar. Nothing leaves the machine until the PIN is entered: one PIN unlocks every Slack tile on that dashboard page until the auto-lock idles out, a reload asks again, and the lock button on a send tile's title bar ends it early. Admin config is in four groups: Slack account (the location account's User OAuth Token — xoxp-…, so messages are literally from the campus — or a bot token plus "Send as"), Channels (the joined channels to follow, one transcript tile each), Transcript (refresh interval, messages kept, thread replies) and Sending (the switch on the group's title row, a 4–8 digit PIN, auto-lock minutes, quick replies one per line as Label | Message — add | #channel to bind one to a channel — and up to eight quick emojis). Tile settings: avatars, timestamps, names and channel notices.

  • Resi Cues — how long until the next Resi cue point, for a campus running video from another site. The tile is one number, as large as it will go: the countdown to the next cue, its name above it, and the playhead and the cue just passed underneath. It also offers that countdown and the playhead to the Timers module, so they can sit among the ProPresenter timers instead of in a tile of their own. Both the cue list and the decoder's position come from Resi's cloud rather than the decoder — the decoder reports upstream and central.resi.io hands it back — so nothing is installed at the decoder end. Resi republishes a position only every few seconds and each reading is already stale, so the playhead is estimated between readings rather than repeated; a countdown built straight from Resi's number sits seconds behind and moves in lurches. Admin config: Resi login and password, which decoder to follow (the list is read from the account), and a folded Timing group for the poll intervals and a position trim. Tile settings: cue name, previous cue, playhead, cue list.

  • Band Lineup — the backstage stage board: everyone on stage in their mic slot with photo, name and mic/pack label, on one shared board that every screen sees the same way — whoever edits it changes it everywhere, over SSE. A photo library fills it: point the module at a Google Drive folder shared "anyone with the link" (file name → person's name) or at a folder on the ProdDash machine, and photos added or removed there follow. Edit in the title bar opens that library — drag a photo onto a slot, drag between slots to swap, rename or clear. Planning Center is optional auto-fill on top, not the source of truth: Sync reads the upcoming plan's team members and drops each into the slot matching their position, filling only slots nobody placed by hand, so a guest pinned on Thursday survives Sunday's sync. Birthdays in the service week (Wednesday→Tuesday) bring a gold glow and raining confetti, and a Choir button adds the extra spot for the weeks there is one. Admin config: Planning Center credentials, service type and plan, the teams to include, the stage slots (one mic/pack label per line, in stage order), default columns, and the photo folder. Tile settings: parallax, names, mic labels, and birthday confetti with its intensity and a test picker — columns are − / + in the title bar.

  • Service Times — every campus's Sunday service times, read from the church website and re-read on a timer, so the board follows the site when the times change through the year. Any service can be marked for production — issue, replay, or do not use — with a note, and a campus taking resi records which of the origin's services it is playing. Marking a broadcast service "do not use" flags every campus riding on it, which is the question the board exists to answer. Marks are shared by every tile and every browser, survive a restart, and expire on their own so last week's never greet a new Sunday. The + picker offers the whole board or a single campus. Admin config is in four groups: Website (address, which campuses to follow, refresh interval), Broadcast (the campuses the broadcast comes from, and each other campus's resi source), Manual campuses (a stopgap for a campus the site has not published yet — the website takes over as soon as it does) and Marks (how long a mark lives). Tile settings: campuses, card or list layout, and a Show group for the day, role, resi source, campuses fed, notes and the updated line.

  • Clock — a big booth clock; also the smallest possible module and the reference for module authors.

To develop modules against mocks instead of real gear: node tools/prodcom-mock.js (ProdCom on 127.0.0.1:24480), node band-lineup-display/tmp/pp-mock.js 1599 (ProPresenter slides on 127.0.0.1:1599), node tools/pp-timers-mock.js 1600 (ProPresenter timers + timecode on 127.0.0.1:1600), node tools/pco-mock.js (Planning Center Services on 127.0.0.1:24700 — run ProdDash with PCO_PLAN_API_BASE=http://127.0.0.1:24700) and node tools/slack-mock.js 24716 (the Slack Web API on 127.0.0.1:24716 — run ProdDash with SLACK_API_BASE=http://127.0.0.1:24716/api) and node tools/pco-band-mock.js 24710 (Planning Center for the Band Lineup board — a plan, its team members, birthdays and photos — run ProdDash with BAND_LINEUP_API_BASE=http://127.0.0.1:24710). See the testing section of the module guide.

Install as a desktop web app

Open the page in a browser first, then:

  • macOS — Safari: File → Add to Dock…
  • macOS/Windows — Chrome: click the install icon in the address bar, or ⋮ menu → Cast, save and share → Install page as app…
  • Windows — Edge: ⋯ menu → Apps → Install this site as an app

Note: Chrome only offers the one-click PWA install on http://localhost (a "secure context"). When opening from another machine over plain HTTP, use Edge's "Install this site as an app" or Chrome's ⋮ → Cast, save and share → "Create shortcut…" (check "Open as window") — same result: a dock/taskbar app in its own window.
