HARDENING, NOT THE FIX for the grey Regions tab. That tab has been seen loading
grey on first load and coloured after a reload. This closes one ordering that
can reach a flat-grey fill. On built bundles that ordering did not reproduce the
grey tab (0 of 20 loads grey, the fill present with its expression at addLayer),
so the reported bug stays open; the lead is the dev/HMR re-mount path.
THE ORDERING. regionFillExpression builds a ['match'] from props.points; with
no points it returns a FLAT no-data grey. addLayers SNAPSHOTS that value into
the layer's paint when it creates the layer. applySubject does repaint the fill
correctly, but it guards every write on getLayer() — deliberately — so a change
arriving BEFORE the layer exists is silently dropped and never retried. And on
MapLibre, the DEFAULT engine, the country boundaries are added as an EMPTY
source and populated by a later fetch's setData(), which nothing repainted
after. In that ordering the fill keeps the colour it was born with.
THE CHANGE is one call: repaint after the boundaries setData, which is the first
moment the layer has any features on the MapLibre path and the only repaint
guaranteed to run with both inputs present. applySubject is idempotent and
getLayer-guarded, so it is harmless when the colour was already right — it only
removes the ordering's power to be the last word.
★ TWO THINGS I GOT WRONG FIRST, both caught by the gate rather than by review,
and both recorded because the wrong version was plausible:
1. MY MODEL COULD NOT REPRODUCE THE BUG. The first version's negative control
fired: no arrival order greyed even with no repaint, so it could not have
detected what it existed for. The greying order is not "data before the
layer" — by then the snapshot is already coloured. It is points arriving
AFTER both addLayers and its mount repaint, with the watch's repaint not
landing. Corrected, exactly 1 of 3 orders greys without the fix and none
with it.
2. I BLAMED THE EMPTY SOURCE, WHICH CANNOT CAUSE GREY. An empty source draws
NOTHING; fill-color is an expression over feature properties. A grey
landmass therefore means features ARE present and the expression came back
flat. The repaint after setData is still required, for the narrower reason
above. The gate carries that correction so the wrong reason cannot be
inherited from a comment.
THE GATE'S OWN INSTRUMENT WAS WRONG TWICE TOO. A 400-char window between
setData and the repaint failed on the repaint's own comment. Widening it to
1600 then PASSED when I deleted the real repaint and left an unrelated
applySubject() 1200 chars downstream — measured, not feared. A distance is the
wrong instrument, so the .then() block is now extracted by brace matching and
the repaint required INSIDE it. The first structural attempt anchored on the
nearest '=>' and landed inside the callback body, because `for (const f of ...)`
has one; it anchors on the enclosing '=> {' now. Four arms mutation-tested,
including that decoy, and every mutated file restored byte-identical.

plugin-designs/ — where YOUR maps live
The shared template lives in ../library/ (aliased @map) — you never edit it per-map.
You build your map by making a folder here, plugin-designs/<your-map>/, and composing the
template's building blocks. Your folder is yours (colors, API, i18n); the template is shared
(Apache-2.0, propagated to every map on the next build).
Shared vs. yours — the balance
library/ (@map) ── SHARED, reusable, parameterized ──► legend · map · map-controls
│ (every map reuses these)
│ imported by
▼
plugin-designs/<your-map>/ ── YOURS ──► the map's "main" class (the .vue profile = the Vue
│ instance for that map)
└── src/ ── YOURS ──► this map's OWN non-reusable components, colors, API, utils
One bundle can hold as many maps as you want — add another .vue profile and rebuild.
- Reusable →
library/. The legend, the map, the map-controls are shared, parameterized components every map reuses. Fix once, every map benefits. Never edit it to customize one map. - This map's own →
plugin-designs/<your-map>/. It holds two things: the map's "main" class (each.vueprofile is the Vue instance for that map) and that map's own non-reusable components (insrc/). Nothing here leaks to another map. - Many maps per bundle. The bundler bundles one map or many — add another flat
.vueand rebuild.
Production or experimental — every profile declares itself
Every app profile is one of two things, and experimental profiles are unlimited and encouraged — create as many as you need:
- Experimental, not built: prefix the folder with
_— the build skips it; it just sits in code. Zero cost, zero risk. - Experimental, built: builds normally, but it belongs in the Experimental section of the power app's layout (nav section) — never embedded on partner surfaces.
- Production: a real product — main sections of the power app + individually embeddable.
(The power app = the SPA layout that composes all profiles into one application.)
The pattern in one picture
plugin-designs/<your-map>/ ← one FOLDER = one BUNDLE, named after the folder
├── index.js ← entry: registers the custom element, finds the profiles
├── overview.vue ← one .vue = one PROFILE (flat in the folder — no profiles/ subfolder)
└── detail.vue ← another profile in the SAME bundle
builds to ─────────────► public/dx-maps/<your-map>/<your-map>.js (one file)
- Folder name = bundle name. Folders starting with
_or.are skipped (handy for WIP). - Each
.vue= one profile (one map screen). One bundle can hold many. - Pick the profile at embed time with the
profilefield — every profile shares one bundle:
<script src="/dx-maps/<your-map>/<your-map>.js"></script>
<your-map profile-config='{"profile":"overview","tk":"pk.eyJ..."}'></your-map>
<your-map profile-config='{"profile":"detail","tk":"pk.eyJ..."}'></your-map>
Add a map — three steps
# 1. create the folder + one profile
mkdir -p plugin-designs/<your-map>
# index.js ← copy doxa-simple-map/index.js, rename the tag
# <name>.vue ← your screen, built from @map/* blocks (flat in the folder)
# 2. build
npm run build # → public/dx-maps/<your-map>/<your-map>.js
# (just this one: BUNDLE=<your-map> npm run build:bundle)
# 3. embed the script tag + element (dev staging at `npm run dev` shows a paste-ready snippet)
Your three things (everything else is shared)
- Colors — how pins are colored. Pick one the template ships (
getColorStrategy('language-family')), or drop your own inplugin-designs/<your-map>/src/colors/(start fromtemplate-bundle/src/colors/example-mode.js). Never edit@map/colors/to recolor your map. - API — your map reads its data from the
profile-configon the page, so the same bundle points at different data with no rebuild.DataSourceManageracceptscsv(bundled file),api(one JSON URL), orrest-api(a live REST endpoint, the default). Prefer the real API over inlined JSON. - i18n — the template ships 11 base locales in
@map/i18n/locales/. UseuseI18n()for strings andRTL_LOCALESfor right-to-left; add or override strings from your own profile.
The one hosting variable
The only thing that changes between hosting modes is the <script src>: a relative path when
your own site serves the file, or an absolute CDN URL when a partner site serves it. The bundle
is identical either way. See ../documentation/CONTRIBUTING.md for the two CDN modes and partner-site embedding.
Profile patterns (mix freely)
- Individual — one
.vueper bundle (simplest). - Parameterized — one profile, behavior driven by
profile-configprops (e.g.tabs[]). - Nested — one profile that renders others (workbench-style, like
doxa-research-map).
