packages/core/package.json:25
- Since
filesonly includesdist, a cleannpm packornpm publishhas no generated entry files: this new build script is never invoked by a lifecycle hook. Addprepack(as the existing embed package does) so a release cannot silently ship a package withoutdist.
"scripts": {
"build": "tsdown src/index.ts --format esm --dts"
packages/core/package.json:25
- The new build script invokes
tsdown, but core does not declaretsdownin its own devDependencies; it is available only because the map workspace happens to add it to the monorepo install. Building this workspace/package independently therefore fails with a missing binary. Add the build tool to core's devDependencies and refresh the lockfile.
"scripts": {
"build": "tsdown src/index.ts --format esm --dts"
packages/core/package.json:15
- This is a scoped package intended for other developers, but its
publishConfigdoes not setaccess: public. A plainnpm publishtherefore defaults to a restricted package, unlikepackages/embed/package.json, so the package is not publicly installable unless every publisher remembers an extra CLI flag; set the publish access explicitly.
"publishConfig": {
"main": "./dist/index.mjs",
packages/core/package.json:19
- The published declaration points at
dist/index.d.ts, but the public core API exposes manygeojsontypes (for exampleGeoLibreLayer.geojson: FeatureCollection) while@types/geojsonremains dev-only. A clean consumer install can therefore fail to resolve thegeojsontype module; promote it todependenciesand refreshpackage-lock.json.
"main": "./dist/index.mjs",
"types": "./dist/index.d.ts",
"exports": {
".": {
"types": "./dist/index.d.ts",
packages/core/package.json:19
tsdown --format esm --dtsemits the ESM declaration with the.d.mtssuffix (as the new map package configuration expects), not.d.ts. These twotypesentries therefore point at a file that will not be indist, so TypeScript consumers of the published core package cannot resolve declarations. Point both entries to./dist/index.d.mts, or configure the build to emit.d.tsconsistently.
"main": "./dist/index.mjs",
"types": "./dist/index.d.ts",
"exports": {
".": {
"types": "./dist/index.d.ts",
packages/map/package.json:28
- Since
filesonly includesdist, a cleannpm packornpm publishhas no generated entry files: this new build script is never invoked by a lifecycle hook. Addprepack(as the existing embed package does) so a release cannot silently ship a package withoutdist/headless.mjsand its declarations.
"scripts": {
"build": "tsdown src/headless.ts --format esm --dts"
},
packages/map/package.json:23
- The new published export map exposes only
.. It therefore makes the documented@geolibre/map/headlessentry and the existing./derived-geometry/./pmtiles-layerentrypoints unavailable to npm consumers (ERR_PACKAGE_PATH_NOT_EXPORTED). Define the intended public subpath exports and build their target files, or update/remove the source contracts; exposing only the root silently makes these imports fail.
"exports": {
".": {
"types": "./dist/headless.d.mts",
"import": "./dist/headless.mjs"
}
packages/map/package.json:49
- Although the published root is headless, this manifest still makes React/React DOM, Cesium, and
maplibre-gl-layer-controlinstall-time dependencies. Every consumer therefore downloads the full UI/3D dependency set that the headless bundle does not import, undermining the stated no-React/no-Cesium entry. Split the full-app entry or move those dependencies out of this published package.
"react": "^19.0.0",
"react-dom": "^19.0.0"
packages/map/package.json:17
- This is a scoped package intended for other developers, but its
publishConfigdoes not setaccess: public. A plainnpm publishtherefore defaults to a restricted package, unlikepackages/embed/package.json, so the package is not publicly installable unless every publisher remembers an extra CLI flag; set the publish access explicitly.
"publishConfig": {
"main": "./dist/headless.mjs",
packages/map/src/headless.ts:34
- This adds a public stateful
LayerSyncAPI without a focused test for its add/update/remove/reorder/dispose behavior. The existing frontend suite covers related exporters and controllers, but not this wrapper, so a regression in its cleanup or ordering semantics can ship in the npm bundle unnoticed. Add a small mock-Map test for the new API before publishing it.
sync(layers) {
const nextIds = new Set(layers.map((layer) => layer.id));
for (const previous of synced) {
if (!nextIds.has(previous.id)) removeLayerFromMap(map, previous.id, previous);
}
packages/map/src/headless.ts:3
- This entry is not actually independent of the Zustand store: the runtime modules it imports use
@geolibre/core, whose root index exports./store, and that module importszustandandzundo. Importing the published headless bundle can therefore load those store dependencies, contradicting the new documentation; expose the needed core utilities from a store-free leaf entry or revise this guarantee.
* Headless entry (`@geolibre/map/headless`): data loading + layer
* synchronization without React, the zustand store, Cesium, or map controls.
packages/map/src/headless.ts:37
syncLayerdoes not reconcile the blend-mode registry by itself.MapController.syncLayerscallssyncLayerBlendModes(layers)and map creation callsinstallLayerBlendModes; this headless wrapper does neither (and the published entry does not export those lifecycle functions), soGeoLibreLayer.style.blendModeis never applied for headless consumers. Install the renderer hooks and sync the registry as part of this wrapper, including any required repaint, or explicitly remove blend-mode support from the headless contract.
for (const layer of layers) syncLayer(map, layer);
packages/map/src/headless.ts:24
- This caveat is contradicted by the implementation:
sync()callssyncLayer()for every layer on every pass, and the existing-layer path moves each layer to the top, so bottom-to-top input order does restack existing layers. Leaving this note in the public entry is likely to make consumers believe reordering is unsupported; update it to describe the actual behavior.
* ponytail: bottom-up re-add ordering gives correct stacking on insert and
* append, but moving an existing layer mid-stack does not restack until it is
* removed and re-added. Full anchor logic lives in MapController.
* getBeforeStyleLayerId; port it here if in-place reordering matters.

- packages/core/package.json: move the dist `main`/`types`/`exports` out of `publishConfig` semantics that npm ignores. npm only honors publish-time *config* there (npm/cli#7586), so the tarball advertised `./src/index.ts` while `files` shipped only `dist`. The published entries now go through `scripts/prepare-npm-package.mjs`, which hoists them just before publish; `publishConfig` also gains the missing `access: public` for a scoped package. Fixes the Copilot and CodeRabbit threads on this file. - packages/core/package.json: `types` pointed at `./dist/index.d.ts`, but `tsdown --dts` emits `index.d.mts`. Published consumers would have gotten no types at all. Answers the Claude review question about the extension. - packages/map/package.json: point `main`/`types`/`exports` back at TypeScript source. Pointing them at `dist` is what broke CI: `dist` is gitignored and nothing builds it, so 12 frontend tests failed with ERR_MODULE_NOT_FOUND on `@geolibre/map/derived-geometry` and friends. The published dist entries live under `publishConfig` and register every subpath the repo exports (`.`, `./headless`, `./derived-geometry`, `./pmtiles-layer`), so nothing 404s on npm. - packages/map/package.json: restore the `^19.0.0` react/react-dom peer ranges. Narrowing them to `^19.2.8` was unrelated to packaging and only constrains consumers. - apps/geolibre-desktop/tsconfig.json, vite.config.ts: revert the `@geolibre/map` path/alias and the `../../packages/map/src` include. With the manifest resolving to source again they are unnecessary, and the include made `tsc -b` emit `.js`/`.d.ts` beside the map sources. Fixes the CodeRabbit thread on tsconfig.json. - packages/map/src/headless.ts: restore the requested stack order when a layer moves. `syncLayer` on an existing layer leaves it where MapLibre put it, so a reorder was silently ignored and the documented bottom-to-top order stopped holding. Rebuild from the lowest position whose occupant changed. - Add scripts/prepare-npm-package.mjs plus tests/prepare-npm-package.test.ts, which also guards that every published path is one the package's own tsdown entries actually emit. - Add tests/headless-layer-sync.test.ts covering ordering, insertion, removal and dispose. - Add .github/workflows/publish-packages.yml: build, prepare and publish @geolibre/core then @geolibre/map on each GitHub Release, via npm Trusted Publishing with provenance, skipping a version already on the registry. - Add READMEs for both packages (npm renders them) and document the source-vs-dist split in CLAUDE.md.

- .github/workflows/publish-packages.yml: read each package's own version for the registry check instead of using core's for both. The two move in lockstep today, but the moment they diverge the map check would skip an existing release or attempt one npm has already seen. - CLAUDE.md: correct the claim that no workflow runs the package builds. The release workflow does build both; what it does not do is verify that every path the manifest publishes names a file the build emitted, which is what tests/prepare-npm-package.test.ts covers.
