ol-pmtiles PMTilesVectorSource doesn't work with OpenLayers 10+

[peter-alexander]

PMTilesVectorSource only works with OL 9, not with the current versions.

<script src="https://cdn.jsdelivr.net/npm/ol@v10.8.0/dist/ol.js"></script> <script src="https://unpkg.com/ol-pmtiles@2.0.2/dist/olpmtiles.js"></script>

Example from: https://github.com/protomaps/PMTiles/tree/main/openlayers

const vectorLayer = new ol.layer.VectorTile({
declutter: true,
source: new olpmtiles.PMTilesVectorSource({
url: "https://r2-public.protomaps.com/protomaps-sample-datasets/nz-buildings-v3.pmtiles",
attributions: ["© Land Information New Zealand"],
}),
style: new ol.style.Style({
stroke: new ol.style.Stroke({
color: "gray",
width: 1,
}),
fill: new ol.style.Fill({
color: "rgba(20,20,20,0.9)",
}),
}),
});
map.addLayer(vectorLayer);

util.js:29 Uncaught TypeError: Cannot read properties of undefined (reading 'ol_uid')

Does it work with ol10 if you use a bundler (the ESM or CJS builds)? This might be a consequence of the way the script-includes (IIFE) build is created.

[peter-alexander]

In a minimal Vite/ESM setup it works with OpenLayers 10.8.0 when using the ESM/bundler build.

So the issue seems to be specific to the IIFE/script-include build.

I don't think there's anything we can do there, because the IIFE needs to bring in part of OL itself. The IIFE build exists for the purpose of having a simple demonstration page, all real use cases of OpenLayers should use a bundler.
