Problem:
The unified Docker image builds the frontend at build time without
VITE_API_URL. Vite inlined import.meta.env.VITE_API_URL as undefined,
so every API call fell back to the hardcoded 'http://localhost:8080'.
This broke Casa deployments where the frontend loaded from the public
domain but tried to reach the backend at localhost.
Solution:
1. Centralize API URL resolution in lib/api-url.ts via getApiOrigin().
It checks runtime window.ENV first (injected by docker-entrypoint.sh
at container startup), then build-time import.meta.env, then dev
fallback. In production unified deployments it returns '' so API
calls use same-origin relative URLs (/api/v1/...) that nginx proxies
to the backend.
2. Replace all 50+ inline import.meta.env.VITE_API_URL || 'localhost'
usages across 14 source files with getApiOrigin() / getApiV1BaseUrl().
3. Add build args and runtime sed substitution to Dockerfile and
docker-entrypoint.sh so the same image works for any deployment.
4. Pass VITE_API_URL through docker-compose.yml and CI/CD build-args.
Verified:
- Production bundle contains 0 occurrences of localhost:8080.
- Container health check and /api/v1/auth/check-users both return 200.
- Runtime injection correctly sets VITE_API_URL='' for same-origin
and VITE_API_URL='https://domain' for external backend.
