OVERVIEW

FLVX (formerly Flux Panel) is a traffic forwarding management system built on a forked GOST v3 stack. It ships as a Go-based admin API (SQLite) + Vite/React UI + Go forwarding agent, with optional mobile WebView wrappers.

WHERE TO LOOK

Task	Location	Notes
Deploy (Docker)	docker-compose-v4.yml	Env: JWT_SECRET, BACKEND_PORT, FRONTEND_PORT
Deploy (IPv6)	docker-compose-v6.yml	Same as v4 + IPv6-enabled bridge
Panel install	panel_install.sh	Picks v4/v6, generates JWT_SECRET, downloads compose
Node install	install.sh	Installs /etc/flux_agent/flux_agent + writes config.json/gost.json + systemd flux_agent.service
Admin API	go-backend/	Go Admin API (SQLite)
Web UI	vite-frontend/	React/Vite dashboard (HeroUI + Tailwind)
Go Agent	go-gost/	Forwarding agent (forked gost + local x/)
Go Core	go-gost/x/	Handlers/listeners/dialers + management API

CONVENTIONS

• Authorization header carries the raw JWT token (no Bearer prefix) between vite-frontend/ and go-backend/.
• go-gost/ uses replace github.com/go-gost/x => ./x and go-gost/x/ is also its own Go module.

ANTI-PATTERNS (THIS PROJECT)

• DO NOT EDIT generated protobuf output: go-gost/x/internal/util/grpc/proto/*.pb.go, go-gost/x/internal/util/grpc/proto/*_grpc.pb.go.
• DO NOT ADD Bearer prefix to Authorization header - expects raw JWT token.
• DO NOT MODIFY install.sh or panel_install.sh locally - CI overwrites these on release.
• DO NOT USE ORM in backend - uses raw SQL with database/sql.
• DO NOT ADD frontend tests - project has no test infrastructure (Vitest/Jest not configured).

COMMANDS

# Panel (Docker)
docker compose -f docker-compose-v4.yml up -d
docker compose -f docker-compose-v6.yml up -d

# Release-based install scripts
./panel_install.sh
./install.sh

# Local dev (per subproject)
(cd go-backend && make build)
(cd vite-frontend && npm run dev)
(cd go-gost && go run .)

NOTES

• LSP servers are not installed in this environment (gopls/jdtls/typescript-language-server); rely on grep-based navigation.
• vite-frontend/vite.config.ts sets minify: false and disables treeshake; expect larger bundles.
• Install scripts (install.sh, panel_install.sh) self-delete after execution - common pattern in one-liner installs.
• CI uses UPX compression on Go binaries before release.
• Backend has contract tests in go-backend/tests/contract/ - frontend has no test infrastructure.
