4grayandClaude Fable 5 cf74f7e4a0 feat(stalker): append portal pages on scroll and drop pagination everywhere (2/2) (#1395)
* feat(stalker): append portal pages on scroll and drop pagination everywhere

Second and final PR of the pagination removal (plan:
.plans/2026-08-09-infinite-scroll-catalog.md). Stalker VOD/series grids now
feed the shared infinite-scroll contract from server-paged appends: portal
pages (server-side size, typically 14) accumulate into one deduplicated
paginatedContent list, page 1 replaces it for the skeleton, hasMoreContent
derives from accumulated length vs total_items (portals that ignore
requested page sizes still terminate), and a failed page > 1 keeps the
accumulated pages on screen with a tail retry (retryContentPage reloads the
same page; loadMore refuses to skip past an unresolved append error). The
facade splits the resource's loading flag by page — skeleton for page one,
tail spinner for appends — and keeps per-identity scroll offsets for
Stalker's INLINE detail round trips; the shared view re-arms its one-shot
restore when a detail opens in the same component instance.

The transitional supportsInfiniteScroll flag and every paged member are
deleted from PortalCatalogFacade; the shared catalog view loses the
mat-paginator, the ?page= round-trip, and the paged query-param branch. The
ITV all-channels grid becomes a client-side render window over the cached
full list (the app's last paginator), and Stalker search pages past its
first capped request via the layout's nearEnd, with a progress guard for
portals that report no usable total.

Validation: 1600 unit tests across 7 projects green (new: vod/series
append + failed-append retry, facade loading split/loadMore guards/scroll
snapshots, ITV window model, compat selector update); catalog-sorting e2e
5/5 (Stalker spec rewritten to scroll model with p>=2 network asserts and
an inline-detail spot-restore round trip; one unrelated nav-timeout flake
reproduced only under parallel machine load), search e2e 16/16, web
stalker e2e green (all-channels grid asserts the windowed count instead of
a paginator range label); lint clean; release note added and validated;
stalker-portal.md, CLAUDE.md, and ui-guidelines updated.

* fix(stalker): reset paging on content-type switch and never skip failed search pages

Round-1 review findings on #1395:

1. Codex P1: switching /vod -> /series with the same category id ('*' on
   both section roots) left page > 1 in place — setSelectedContentType did
   not touch paging and setSelectedCategory('*') no-ops on an unchanged id
   — so the new type's FIRST response was treated as an append onto the
   old type's accumulated list. The type setter now resets the page (and
   no-ops entirely when the type repeats, keeping detail round-trip
   restores intact).

2. Greptile P1 + Codex P2: a failed search append left searchHasMore true,
   so the next near-end advanced to page N+1 and permanently omitted the
   failed page. The search now tracks searchAppendError: a failed append
   keeps the accumulated pages and the next near-end RETRIES the same
   page; a failed fresh search (page 1) clears the previous query's cards
   instead of rendering them under the new term (Codex P2).

The page-merge/failure logic moved into applySearchPageSuccess/Failure
methods: Angular resource() never re-fires on params changes in this
repo's template-less jest harnesses (store-hosted resources do), so the
extracted methods carry the unit coverage — accumulation + dedupe,
no-total progress guard, retry-not-skip, fresh-failure clear — plus a
selection spec for the type-switch page reset. portal-stalker-feature
260, portal-stalker-data-access 464, lint clean; catalog-sorting e2e 5/5
and web stalker e2e green. search.e2e shows machine-load nav-timeout
flakes on unrelated M3U/live specs (a runaway third-party process pegs
the host CPU); CI provides the clean independent run.

* fix(stalker): include the portal in the search paging identity

Round-2 Codex P1 on #1395: Angular reuses the search route across
/stalker/A/search -> /stalker/B/search, and the paging identity covered
only term + filter — the page number and accumulator survived the portal
change, so the next near-end fetched portal B at the OLD page number and
appended it onto portal A's results while skipping B's first page.

The active playlist id now joins the page-reset identity, the resource
params, the stale-response guard, and the layout's near-end reset key.
Regression spec: switching the active playlist on a reused route resets
the page to 1 and rotates the scroll reset key.

* fix(stalker): end paging on no-progress appends even with a reported total

Round-3 Codex P2s on #1395 (same defect in both accumulators): the
no-progress guard only applied when the portal reported no usable
total_items. After a mid-list portal mutation, deduplication can leave
the unique list permanently shorter than the claimed total — hasMore then
stayed true forever and every scroll crossing kept requesting pages past
the end of the data.

An append that adds no unique items now ends paging in both places: the
catalog clamps totalCount to the accumulated length (hasMoreContent turns
false and the count badge reflects what is actually reachable), and the
search requires append progress in the total-backed branch exactly like
the no-total branch. Regression specs cover a duplicate page under a
larger claimed total for both. portal-stalker-data-access 465,
portal-stalker-feature 262, lint clean.

* fix(stalker): explicit search retry control and per-portal scroll identities

Round-4 findings on #1395:

1. Greptile P1: with the results pane parked at the bottom, repeated
   append failures exhausted the scroll auto-fill budget while the
   near-end latch stayed armed — the retry path was reachable only
   through another nearEnd event that could never fire. The search page
   now renders an explicit retry control under the results whenever an
   append has failed (same wording as the catalog grid tail), wired to
   the existing retry-same-page path, so recovery never depends on
   producing another scroll event.

2. Codex P2: the facade's saved-scroll map survives a same-config portal
   switch (the vod/series route provider is reused across /stalker/A ->
   /stalker/B), and its identity lacked the playlist — portal A's offset
   could restore onto portal B's unrelated catalog. The playlist id now
   leads the scroll identity; regression spec covers the cross-portal
   non-restore and the return restore.

portal-stalker-feature 263, lint clean.

* fix(stalker): restore the search results scroll after an inline detail

Round-5 Codex P2 on #1395: the search layout destroys the results
container while an inline detail is shown (showDetails) and recreates it
at offset zero — with the new multi-page accumulation a user could load
several pages, open a result far down the list, and land back at the top
on close even though the accumulated results survived.

SearchLayoutComponent now exposes a scroll handoff for hosts whose
details replace the results (getResultsScrollTop /
restoreResultsScrollTop on the container it owns), and the Stalker search
captures the offset when a detail opens and restores it one-shot after
the container is recreated on close. Regression specs cover the layout
handoff methods and the capture/restore round trip.
portal-shared-ui 90, portal-stalker-feature 264, lint clean.

* fix(stalker): clear accumulated search results for unsearchable portals

Round-6 Codex P2 on #1395: the loader's early returns (deleted or
malformed playlist on a reused route) predate the accumulator and
returned [] without touching it — the previous portal's cards kept
rendering under the new context once loading settled.

Every no-portal early return now goes through resetSearchAccumulator(),
which empties the accumulated list and both paging flags; the short-term
path uses it too (and now also clears a stale append error). Regression
spec covers the full reset. portal-stalker-feature 265, lint clean.

Note: First version of the application which was developed as a PWA is available in an extra git branch.

Self-hosted PWA

The Docker setup builds the Angular PWA and the monorepo web backend into one image. The backend handles remote M3U parsing plus Xtream and Stalker proxy requests under /api, so a separate 4gray/iptvnator-backend container is not required for the default self-hosted flow.

docker compose -f docker/docker-compose.yml up --build -d

The application is available at http://localhost:4333. See docker/docker-compose.yml for the ready-to-run compose file and docker/README.md for environment variables, reverse proxy notes, PWA limitations, and build details.

The self-hosted image runs the browser PWA rather than the Electron desktop app: EPG/XMLTV panels, Embedded MPV, managed MPV/VLC launching, the download manager, and Electron remote-control features are not available there. If browser playback fails, copy the stream URL and open it manually in an external player such as MPV, VLC, or IINA.

Download

Download the latest version of the application for macOS, Windows, and Linux from the release page.

Alternatively, you can install the application using one of the following package managers:

Homebrew

$ brew install iptvnator

Snap

$ sudo snap install iptvnator

Arch

Also available as an Arch PKG, iptvnator-bin, in the AUR (using your favourite AUR-helper, .e.g. yay)

$ yay -S iptvnator-bin

Gentoo

You can install IPTVnator from the gentoo-zh overlay

sudo eselect repository enable gentoo-zh
sudo emerge --sync gentoo-zh
sudo emerge iptvnator-bin

Linux Embedded MPV Support

Embedded MPV on Linux is experimental and currently supports x64 desktop sessions where IPTVnator runs under X11 or Xwayland. Native Wayland embedding is not supported yet. Linux package launchers request X11 with --ozone-platform=x11, so Wayland desktops still need Xwayland available.

The Linux backend starts a system mpv executable with --wid, so mpv must be installed and available on PATH. CI validates the Linux native addon and standard packages on Ubuntu 22.04, with Flatpak packaging built on Ubuntu 24.04. Expected user targets are Ubuntu/Debian .deb, Arch/Manjaro pacman, RPM distributions, and AppImage on x64 systems with X11/Xwayland plus mpv installed. Flatpak and Snap builds remain available, but embedded MPV is not announced as supported there yet because those sandboxed formats do not expose the host mpv executable to the embedded backend by default.

Get it from the Snap Store

Troubleshooting

macOS: "App is damaged and can't be opened"

Older unsigned macOS builds may require removing the quarantine flag from the downloaded application:

xattr -c /Applications/IPTVnator.app

Alternatively, if the app is located in a different directory:

xattr -c ~/Downloads/IPTVnator.app

Linux: chrome-sandbox Issues

If you encounter the following error when launching IPTVnator:

The SUID sandbox helper binary was found, but is not configured correctly.
Rather than run without sandboxing I'm aborting now.
You need to make sure that chrome-sandbox is owned by root and has mode 4755.

Solution 1: Fix chrome-sandbox permissions (Recommended for .deb/.rpm installations)

Navigate to the IPTVnator installation directory and run:

sudo chown root:root chrome-sandbox
sudo chmod 4755 chrome-sandbox

Solution 2: Launch with --no-sandbox flag

Edit the desktop launcher file to add the --no-sandbox flag:

  1. Find your desktop file location:

    • Ubuntu/Debian: ~/.local/share/applications/iptvnator.desktop
    • System-wide: /usr/share/applications/iptvnator.desktop
  2. Edit the file and modify the Exec line:

    Exec=iptvnator --no-sandbox %U
    
  3. Save the file and relaunch the application from your application menu.

Alternatively, you can launch IPTVnator from the terminal with the flag:

iptvnator --no-sandbox

GNU/Linux: Wayland startup failure

If IPTVnator exits on GNU/Linux with errors about failing to connect to Wayland or initialize the Ozone platform, force X11/XWayland instead:

iptvnator --ozone-platform=x11

This workaround is mainly for older or problematic Linux graphics stacks. The Snap package already includes this X11 override by default. For AppImage, direct binaries, and other Linux package formats, pass the flag manually when needed.

How to Build and Develop

Requirements:

  • Node.js with pnpm (via Corepack)
  1. Clone this repository and install project dependencies:

    $ corepack enable
    $ pnpm install
    
  2. Start the application:

    $ pnpm run serve:backend
    

This will open the Electron app in a separate window, while the Angular dev server will run at http://localhost:4200.

The equivalent Nx command is:

$ nx serve electron-backend

To start Electron with an empty, isolated data directory instead of your normal ~/.iptvnator folder, set IPTVNATOR_E2E_DATA_DIR for that run:

$ rm -rf .tmp/iptvnator-empty && mkdir -p .tmp/iptvnator-empty
$ IPTVNATOR_E2E_DATA_DIR="$PWD/.tmp/iptvnator-empty" pnpm run serve:backend

This redirects the SQLite database, Electron user data, and local config under the given directory. Delete that directory whenever you want a fresh empty state.

If you need startup diagnostics for a white screen or a frozen route, you can also turn on opt-in Electron tracing. These logs are written to the Electron terminal output so they still help when the renderer DevTools never open:

$ IPTVNATOR_TRACE_STARTUP=1 pnpm run serve:backend

Nx equivalent:

$ IPTVNATOR_TRACE_STARTUP=1 nx serve electron-backend

Useful narrower flags:

  • IPTVNATOR_TRACE_IPC=1 logs renderer window.electron.* calls reaching the Electron bridge
  • IPTVNATOR_TRACE_DB=1 logs DB worker requests and request-scoped DB events
  • IPTVNATOR_TRACE_SQL=1 logs SQLite statements in both the main connection and DB worker connection
  • IPTVNATOR_TRACE_WINDOW=1 logs BrowserWindow load, navigation, and unresponsive events
  • IPTVNATOR_TRACE_RENDERER_CONSOLE=1 mirrors renderer console messages into the Electron terminal output

Security-sensitive network compatibility flags are opt-in:

  • IPTVNATOR_ALLOW_PRIVATE_NETWORK_URLS=1 permits strict EPG fetches from playlist metadata (x-tvg-url, url-tvg, or tvg-url) to resolve to localhost, LAN, or other private addresses. Directly configured Xtream/Stalker portals and private playlist servers remain supported without this flag. Prefer the in-app source-scoped “Allow source” action for a trusted EPG URL.
  • IPTVNATOR_ALLOW_INSECURE_TLS=1 disables certificate validation for remote playlist imports and refreshes for the whole Electron process. Prefer the in-app host-scoped trust action for a trusted provider with a self-signed or otherwise invalid certificate.

If the local Nx daemon gets into a bad state before rerunning Electron, reset it:

$ pnpm nx reset

To run only the Angular app without Electron, use:

$ pnpm run serve:frontend
