Three-file config module under src/config/:
- schema.ts: RuntimeConfigSchema (directusUrl, liveWsUrl, businessWsUrl,
optional googleMapsKey, env enum). Custom UrlOrAbsolutePath validator
accepts http(s)/ws(s) URLs plus paths starting with /.
- load.ts: loadConfig() fetches /config.json with cache: 'no-store',
safeParse, throws ConfigValidationError on schema failure.
- context.ts: RuntimeConfigContext + useRuntimeConfig() hook (no JSX).
- provider.tsx: RuntimeConfigProvider — loading / ready / error states.
Single retry after 500ms on network failure; renders zod issues on
validation failure for debuggability.
public/config.json: committed dev defaults (relative paths matching the
Vite proxy from 1.3).
src/main.tsx wraps App in <RuntimeConfigProvider>.
README gains a Runtime config section with the schema table.
Deviation: spec sketched provider+hook in one context.tsx. Split into
context.ts (hook only) and provider.tsx (component only) to satisfy
react-refresh/only-export-components without adding an eslint override.
Same-origin dev proxy via Vite's server.proxy:
- /api/* -> ${VITE_DEV_DIRECTUS_URL}/* (Directus REST + GraphQL)
- /ws-business -> ws://.../websocket (Directus business-plane WS)
- /ws-live -> ${VITE_DEV_PROCESSOR_WS_URL} (Processor live WS, Phase 1.5)
WS proxy targets derive ws:// scheme from the http(s) Directus URL.
loadEnv reads VITE_DEV_* overrides; sensible localhost defaults.
tsconfig.app.json: noUncheckedIndexedAccess + noImplicitOverride.
.env.example documents the two override vars; .env.local is gitignored
via the existing *.local pattern.
README "Local dev" section: proxy table + override instructions + port
collision workaround.
Deviation: spec called for .env.dev.example/.env.dev.local but Vite's
dev mode is "development" not "dev", so mode-specific files would be
.env.development.* and Vite wouldn't auto-load .env.dev.local. Switched
to the standard Vite .env.example/.env.local convention. Documented in
the task's Done section.
Plus: backfill 1.2 commit SHA (9918418) in its Done section.
