Unlike the cog branch just below (which throws labels.cogUnsupported when the capability isn't available), this silently no-ops when appRef is falsy: visualizeAsset returns normally, the caller's try succeeds, and the UI reports labels.added(...) even though nothing was added. appRef can only be null here if the plugin disconnects while the fetch/add is in flight, so this is a narrow edge case, but since this PR already tightened the cog case to fail loudly it'd be more consistent to do the same here, e.g.:
| if (appRef) await addPMTilesLayerFromUrl(appRef, asset.href, { fit: false, name }); | |
| case "pmtiles": { | |
| if (!appRef) throw new Error(labels.addFailed); | |
| // The same door the Source Cooperative browser uses, so an archive reaches the map one way. | |
| await addPMTilesLayerFromUrl(appRef, asset.href, { fit: false, name }); | |
| return; | |
| } |
Confidence: low-medium — only reachable if the STAC plugin disconnects mid-request, but the resulting silent "success" is misleading if it ever happens.

Fixed in 3969cfe. It now throws labels.addFailed when appRef is missing, matching the cog branch.

pendingPMTilesNames is keyed only by archive URL. If two addPMTilesLayerFromUrl calls for the same URL are in flight at once (e.g. two STAC items — or a STAC item and the Source Cooperative browser — referencing the same shared .pmtiles asset, added in quick succession), the second call's setPendingPMTilesName overwrites the first's entry before the first's layeradd handler consumes it via resolvePMTilesLayerName. Whichever layeradd fires first "steals" the second caller's name, and the other add is left to fall back to layerNameFromUrl.
This is a narrow race (requires concurrent adds of the identical URL), so low confidence/severity, but worth noting since nothing currently disambiguates concurrent requests for the same archive.
There was a problem hiding this comment.
Fixed in 3969cfe: pending names are queued per URL, so concurrent adds of one archive each take their own, and the disposer removes only its own entry. Two tests cover it.
On the related timing question, the control emits layeradd synchronously inside its own add (ControlGrid-CLX7mzG3.js: this._render(), this._emit("layeradd", ...) in the try block), so the handler has spent the name before the await returns. The disposer covers the archive that throws before emitting. Noted in a comment at the call site in fe844cf.

Minor robustness nit (low confidence — not reachable with the current sole caller, which always builds a non-empty template string): if (pending) return pending.name; checks the queue entry object's truthiness, not the name itself. If a caller ever passed name: "" to addPMTilesLayerFromUrl, this would return the empty string instead of falling through to layerInfo.name || layerNameFromUrl(...), leaving the layer with a blank name.

4799-4802: 🗄️ Data Integrity & Integration | 🟡 Minor | ⚡ Quick winGuard cleanup against a replacement queue.
resolvePMTilesLayerNameremoves the map entry when it consumes the last queued name. The disposer still holds that empty queue. If another same-URL request registers a name before the old disposer runs, the unconditional delete at Line 4802 removes the new queue. The next layer then falls back to the archive or URL name and loses the caller-provided STAC context.Delete the map entry only when it still points to this queue. Add a regression test for resolving the old entry, queuing a new name, and then invoking the old disposer.

Possible mis-assignment under concurrent adds of the same PMTiles href.
resolvePMTilesLayerName shifts the oldest entry off the per-URL pendingPMTilesNames queue on every layeradd event for that URL. That's correct only if the order names are pushed (setPendingPMTilesName, called synchronously before await pmtilesControl.addLayer(url)) always matches the order layeradd events later fire for that URL.
If two STAC items reference the exact same asset href (a shared basemap/mosaic tile, or a user clicking Add twice quickly) and are added concurrently, the first call's addLayer may take longer (cold fetch) than a second, faster call (e.g. already-cached header) for the same URL — the queue would then hand the first pending name to the second (faster) layer, and vice versa. pmtilesControl.addLayer is awaited, so there's no hard guarantee (await yields, so a JS interleaving is possible) that its internal layeradd firing order matches the caller's push order, only the "control emits layeradd synchronously while adding" comment claims it does for a single call — it doesn't establish ordering across two concurrent calls for the same URL.
Confidence: medium — this can't be fully verified without the maplibre-gl-components control's internal source (not vendored in this environment), and the failure mode is a swapped layer name rather than data corruption, but it's worth double-checking the control's concurrency behavior (or scoping the pending-name lookup more tightly, e.g. keyed by a per-call token instead of bare URL) if simultaneous same-URL adds are a realistic use case (e.g. batch-adding STAC items that share a mosaic asset).
There was a problem hiding this comment.
Fixed in 319bc59, though by removing the assumption rather than defending it.
Adds now go through a queue, so only one is in flight at a time and the pending name is a single value instead of a per-URL list. That also covers a bigger hazard than name ordering: the control keeps the URL it is loading on itself and reads it back after awaiting the header (PMTilesLayer.ts: addLayer sets this._state.url, _addLayer reads it at the guard, at new PMTiles(), at the pmtiles:// URL, and in the layeradd payload), and it clears this._state.error on entry while callers read getState().error after awaiting. Overlapping adds could therefore load each other's archive or mask each other's failure.
Being straight about the evidence: that is read from the control's source, not reproduced. I fired two Adds back to back through the STAC panel with the queue bypassed and both still landed correctly, so I have no repro through a GeoLibre path. The queue is defensive.
The real fix is upstream in maplibre-gl-components: snapshot the URL at the top of _addLayer, and have addLayer return the created layer id and throw on failure. That would let this queue, the pending-name channel, and the getState().error check all go away.

The new "pmtiles" branch explicitly guards against a missing appRef (if (!appRef) throw new Error(labels.addFailed);), but this "geojson" branch still uses appRef?.addGeoJsonLayer(...) unconditionally. If appRef is undefined, the fetch still runs and then silently no-ops — the caller (setStatus(labels.added(...))) reports success even though nothing was added to the map. This behavior predates this PR, but since the PR is already restructuring this exact branch and tightened the same check for the pmtiles case, it'd be worth applying the same guard here for consistency:

setPendingPMTilesName keys the queue by the exact url string passed here, and resolvePMTilesLayerName later looks it up by layerInfo.url from the control's layeradd event (line ~4810). This assumes the third-party PMTilesLayerControl (maplibre-gl-components) echoes back the URL string byte-for-byte unmodified (no trimming, no relative-path resolution, no re-encoding). If it doesn't, the lookup silently misses and the layer falls back to the generic file-name label instead of the caller-supplied name — not a crash, just a silent naming regression for STAC-added PMTiles layers that would be easy to miss in review since it degrades gracefully.
Confidence: low-medium — I can't verify the control's internal event payload from this diff alone (the package isn't vendored in the repo), but it's worth double-checking against the actual library behavior or adding an assertion/log if the URLs ever diverge.

This call doesn't set opacity, so createPMTilesStoreLayer defaults it to 1 for both vector and raster archives. Elsewhere in this same PR, BasemapExtractPanel.tsx explicitly sets opacity: info.tileType === "raster" ? 0.6 : 1 with the comment "raster-opacity reads the layer-level opacity, not style.fillOpacity" — and indeed rasterPaint() (packages/map/src/style-mapper.ts) wires raster-opacity to layer.opacity, not to style.fillOpacity. Since this function passes no style override either, a raster PMTiles asset added from a STAC item renders at full opacity instead of the dimmed 0.6 used by the control and the basemap-extract path, which is a visible inconsistency for imagery-type PMTiles archives.

Minor: signal is only checked before/after readRemotePMTilesInfo, but isn't threaded into it (readRemotePMTilesInfo/PMTiles/the underlying fetch calls have no way to receive it). So closing the panel mid-add discards the result but doesn't actually cancel the in-flight range requests — they still run to completion in the background. Low impact since these are small header/metadata reads, but worth knowing if readRemotePMTilesInfo is ever reused for a slower/bigger read. Confidence: low.

strokeColor is derived from the pre-override fillColor, and options.style is spread last. A caller that passes style: { fillColor: "#00ff00" } without also setting strokeColor ends up with a stroke color that doesn't match the new fill (stroke keeps the sourceLayerColors/default-derived value). No current call site hits this (neither BasemapExtractPanel nor pmtilesStoreLayer override fillColor via style), but the JSDoc on PMTilesStoreLayerOptions.style ("for callers that paint their PMTiles layers their own way") invites exactly this usage.

signal is only checked via throwIfAborted() before and after the read — the underlying PMTiles/range-request fetches inside readRemotePMTilesInfo aren't given the signal, so they aren't actually cancelled when the panel is closed mid-load. That differs from the sibling GeoJSON branch in maplibre-stac.ts, which passes signal straight into fetch. Given the payload here is just the archive header (a few KB), the practical impact is minimal — the in-flight request just gets its result discarded — but it's a bit inconsistent with the cancellation model used elsewhere in the same switch.
Confidence: low — cosmetic/performance, not a correctness bug given the small payload size.

Same as the two threads above: getHeader() takes no signal, only Source.getBytes does. Honouring it would mean a custom Source re-implementing ETag and 416 handling to abort a 16 KB read.

Bug (high confidence): addPMTilesAsset doesn't guard against a vector archive that reports no vector_layers metadata. When info.tileType === "vector" and info.sourceLayers is empty, createPMTilesStoreLayer builds nativeLayerIds: [] (via pmtilesNativeLayerIds), which makes isPlaceholderLayer return true — the layer renders as "This PMTiles layer could not be displayed." Yet addPMTilesAsset resolves successfully, so visualizeAsset reports labels.added(...) ("Added … to the map.") to the user.
This is exactly the class of bug the PR body calls out fixing for GeoJSON ("fails loudly … rather than reporting success after adding nothing"), and BasemapExtractPanel.tsx already guards against this same case explicitly:
// A vector archive whose metadata has no `vector_layers` gives no source
// layers to render, which would add a silent placeholder while reporting
// success. Surface it as an error instead. (Raster archives have none.)
if (info.tileType === "vector" && info.sourceLayers.length === 0) {
setPhase("idle");
setError(t("basemapExtract.errorNoSourceLayers"));
return;
}addPMTilesAsset (new in this PR) has no equivalent check, so a real-world PMTiles asset that omits the optional vector_layers key from its metadata will silently placeholder while the STAC panel reports success.

Fixed in 63632b0. A vector archive with no vector_layers now throws before anything is added, so the panel shows why instead of reporting success. Test covers the rejection and that no layer lands.
Also dropped the dead appRef check you flagged in the same review.

This createPMTilesStoreLayer call doesn't forward info.encoding, unlike the equivalent call in stac-layers.ts (addPMTilesAsset), which does ...(info.encoding ? { encoding: info.encoding } : {}).
readPMTilesArchiveInfo (used a few lines up) now returns encoding: "mlt" for MLT-encoded vector archives, and ensurePMTilesExternalLayer in layer-sync.ts only adds encoding: "mlt" to the MapLibre source when layer.source.encoding === "mlt". Without forwarding it here, an MLT-encoded archive extracted/opened through this flat-overlay path will have its source added without encoding, and MapLibre will try to decode the tiles as plain MVT — likely producing broken/garbled rendering rather than the placeholder-vs-render distinction this PR is otherwise careful about.

Confidence: medium — I can't confirm from this environment whether OpenFreeMap/CARTO-derived archives (the likely inputs to this extractor) are ever MLT-encoded in practice, but the type-level gap and the asymmetry with the sibling call site look like an oversight rather than a deliberate choice.
There was a problem hiding this comment.
Fixed in 3af75bf: the extract path forwards info.encoding too, so an MLT archive is added with encoding: "mlt" there as well.

noSourceLayersMessage is a hardcoded English string, and it's shown to the user verbatim — maplibre-stac.ts's add handler does setStatus(error instanceof Error ? error.message : labels.addFailed, true), so this bypasses i18n entirely.
This is inconsistent with two things in the same PR/codebase:
- CLAUDE.md: "UI strings are translatable via react-i18next … Use
t()for new user-facing strings." - The existing
StacLabels/setStacLabelspattern this very file's caller (maplibre-stac.ts) already uses for all its other user-facing strings (including theaddUnsupportedstring this PR just localized into 19 locale files). - The near-identical message already has a translated key:
basemapExtract.errorNoSourceLayersinen.json("This vector archive has no layer metadata, so it can't be rendered...").
Consider adding a label to StacLabels/setStacLabels (e.g. noSourceLayers) and threading it through addPMTilesAsset, rather than throwing a hardcoded string from the plugins package.
Confidence: medium — functionally harmless (the add still fails correctly), but it's a real localization gap for non-English users, and it goes against a convention this same PR otherwise follows carefully.

Fixed in 3af75bf, along the lines you suggested: addPMTilesAsset now answers null instead of throwing a string, and the panel raises labels.addNoSourceLayers. Added as a new StacLabels key rather than reusing basemapExtract.errorNoSourceLayers, so rewording one feature's message cannot silently change the other's. Translated across all 19 catalogs, matching how feature PRs in this repo ship strings.

You were right to keep raising this — there was a way through after all.
FetchSource.getBytes already takes a signal; the header and metadata reads above it just never pass one. readRemotePMTilesInfo now wraps the library's own source and injects the caller's signal, so the range requests are genuinely cancelled and none of its ETag, 416 or content-length handling is reimplemented.
Test asserts the signal that reaches fetch is the caller's already-aborted one, since the reader makes its own when given none — the earlier version of that assertion passed either way.

There was a problem hiding this comment.
signal here only gates before and after readRemotePMTilesInfo, it isn't threaded into the actual range-request fetches, so aborting (e.g. closing the STAC panel or switching items mid-read) doesn't cancel the in-flight network calls — it just discards the result once they finish. That's a real (if minor) asymmetry with the sibling geojson branch in maplibre-stac.ts, which passes signal straight into fetch() for genuine cancellation. Not a correctness bug (the throwIfAborted() after the await keeps the store consistent), but archives on a slow/large connection will keep downloading range requests in the background after the user has navigated away. Confidence: medium.

No opacity is passed here, so a raster PMTiles archive added from a STAC item renders at full opacity (defaults to 1 inside createPMTilesStoreLayer). Both other call sites that build a raster pmtiles layer explicitly dim it to 0.6 — BasemapExtractPanel.tsx (opacity: info.tileType === "raster" ? 0.6 : 1, with the comment "raster-opacity reads the layer-level opacity, not style.fillOpacity") and the PMTiles control's pmtilesStoreLayer (which forwards the control's own opacity). If the dimming is meant to avoid an overpoweringly bright raster basemap layer, this path skips it; if full opacity is intentional for a foreground STAC overlay, it'd be worth a short comment explaining the deliberate difference so a future refactor doesn't "fix" it into inconsistency.

Confidence: low — this may well be an intentional distinction between "extract as basemap" and "add STAC asset as overlay," but the asymmetry isn't called out anywhere.

Intentional, and now documented in 55a50ad: an asset added from a search result is what the user asked to look at, where a basemap extract is a backdrop. Happy to match 0.6 if you'd rather they agree.

There was a problem hiding this comment.
header.tileType === 6 for MLT is a new magic number with no reference to the PMTiles spec or a pmtiles library enum (the well-documented values are 0=Unknown, 1=Mvt, 2=Png, 3=Jpeg, 4=Webp, 5=Avif). Likewise encoding: "mlt" on the MapLibre vector source (layer-sync.ts's ensurePMTilesExternalLayer) is the only place in the codebase that sets a vector source encoding, so there's no existing precedent to lean on. The only coverage is a synthetic test that patches byte 99 of the fixture archive to 6 — there's no real MLT-encoded fixture exercised end-to-end, so a wrong tile-type number or an unsupported encoding option on the installed maplibre-gl/pmtiles versions wouldn't be caught by the test suite. Worth double-checking header.tileType === 6 and the encoding source option against the actual pmtiles/maplibre-gl versions pinned in this repo (pmtiles ^4.4.1, maplibre-gl ^6.3.0).
Confidence: low-medium — I can't verify the library internals in this environment, but the lack of any comment linking to a spec/changelog and the absence of a real fixture stood out.

Fixed in 55a50ad: the literals are gone, replaced by the library's own TileType.Mvt / TileType.Mlt, so the values track the package rather than a comment.

Closes #1946.
A STAC item's PMTiles asset now lands on the map. The panel reads the archive's header itself — a
range request, a few kilobytes — and builds the layer from what it finds.
Not through
addPMTilesLayerFromUrl, which is where this started and where the Source Cooperativebrowser still goes. That door drives a singleton control which keeps the archive it is loading on
itself and reads it back after awaiting, and reports the outcome on shared state it clears on
entry. Driving it programmatically needed a queue to stop two adds reading each other's URL, a side
channel to name the layer the control created, and a read of
getState().errorto tell successfrom failure. Building the layer here needs none of that: the caller gets its own id, its own name,
and a rejection when the archive will not load. The upstream fix that would make the door safe for
callers — returning the layer id, throwing on failure — is worth having, and this does not wait for
it.
Asset detection moves to a table keyed by media type with an extension fallback, and the router
switches on it exhaustively, so adding a format without handling it fails to compile. A declared
media type outranks any extension, which also fixes a
.pmtileshref under a/geotiff/pathbeing read as a GeoTIFF.
The store layer every PMTiles path builds is now shaped in one place
(
@geolibre/map/pmtiles-layer). MissingsourceKind/externalNativeLayer/nativeLayerIdsis whatmakes a layer render as "could not be displayed", and three call sites each remembered that
separately. The archive readers moved there too, so reading an archive and shaping a layer for it
live together.
Also from review: a GeoJSON asset now fails loudly when the plugin has no app, rather than
reporting success after adding nothing.
Tested with
e2e/stac-pmtiles.spec.ts, which serves a real archive over Range requests and assertsthe layer reaches the map named for its item, plus unit coverage of the shaper, the format table,
and the reader. Checked by hand against a single-source-layer archive and an eleven-layer one.
