…install guides - Build React with Vite → embed via rust-embed into Rust binary (single binary) - Serve React SPA from axum fallback handler; assets served by content type - Restructure router: auth middleware only on /api/v1 routes, SPA bypasses it - Config default path: /etc/coremq/config.yaml (fallback to local for dev) - Data default path: /etc/coremq/data/coremq.redb (COREMQ_DATA env override) - config.yaml updated to use /etc/coremq/ paths for Casbin model/policy - axios.ts: use window.location.origin in production, port 18083 in dev - Dockerfile: 3-stage build (node → rust → debian-slim runtime) - docker-compose.yml: all ports exposed, /etc/coremq volume mounted - build.rs: creates client/dist/ if missing so rust-embed always compiles - Makefile: add build, build-client, build-server, docker-*, install-config targets - docs/install-linux.md, docs/install-macos.md, docs/install-windows.md added Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
