Every reference to the Driver in library/ is reworded: the engineering reason
stays, the speaker and the quote go, and a decision still open reads
"provisional, pending a product decision". Comments only: each changed file
is identical after stripping comments (JavaScript, template and CSS, including
CSS comments inside the style strings shadow-DOM components inject).
Those style-string comments do ship, so several bundles change by exactly
those comment bytes.
No Vue, no Pinia, no Mapbox. Anything reactive is a composable; anything stateful is a store.
File
Purpose
apiBaseUrl.js
Resolves the API base URL at runtime (window.MAP_APP_API_URL / VITE_API_BASE_URL)
embedBase.js
Share/embed URL ladder — the built bundle derives its tree root from its own script url (profileConfig.shareUrl / embedBaseUrl / window.MAP_EMBED_BASE_URL override) so tree-relative <bundle>/<profile>/index.html links work on any host
geoUtils.js
Centroid, bounds, validation, GeoJSON helpers
ClusterHelpers.js
Shared helpers for the two clustering utilities below
MSTClusteringUtil.js
Minimum-spanning-tree clustering for affinity blocks
NetworkClusteringUtil.js
Network-line clustering — connect nearby pins with edges
No import { ref } from 'vue' and no import mapboxgl in this folder — operate on plain
[lng, lat] arrays.
Named exports (for tree-shaking), JSDoc on every export.
Writing reactive logic or needing Mapbox APIs? That's a composable — move it to ../composables/.
