End-to-end PRG → Go RTL → pgxpool → labdb queries → JSON response,
from a single 24 MB binary with no Node.js, FFI, or Apache anywhere
in the request path.
app/bridge_server.prg:
Main now opens a pgxpool handle from LABDB_DSN (or the local
Homebrew default) before HTTP_SERVER_START, then publishes it
via LABDB_SET_PG so request goroutines can pick it up.
BridgeDispatch calls FetchRouteData before the per-path PRG
handler runs. FetchRouteData maps a few /api/* routes to the
same SQL the upstream server.js endpoint runs, encodes results
via hb_jsonEncode, and stuffs them into ctx fields under the
same keys the existing labdb api/*.prg handlers already read
(rows, total, devices, etc.). PRG handlers stay unmodified.
hbrtl_ext/labdb_state/:
Tiny Go RTL that holds the PG handle in a sync/atomic.Int64.
Picked this over a PRG STATIC/PUBLIC variable to sidestep
Five's stricter parser (now that parser.go errors on missing
terminators, anything more elaborate in the entry .prg adds
friction without buying anything).
Verified against a Homebrew postgres@16 cluster seeded with 2 devices
+ 2 sessions:
/api/admin-stats.prg
→ {"devices":2,"sessions":2,"records":0,"active_sessions":1}
/api/sessions-list.prg
→ {"sessions":[...two rows with full fields...],"total":2}
/api/admin-devices.prg
→ {"devices":[...two rows with api_key/created_at...]}
/api/hello.prg (no DB)
→ unchanged from 1a.4-3

fivenode_go
FiveNode for Five — a Harbour-compatible web framework that compiles to a single Go binary. No Node.js, no FFI, no Apache. PRG sources go in, one executable comes out.
Successor to the koffi/N-API based fivenode framework, rebuilt on the Five Pure-Go runtime.
Status
Early bootstrap — Phase 1a in progress.
Architecture
Browser ──── HTTP/HTTPS ──── fivenode_go single binary
├─ Five hbrt VM (PRG interpreter / compiled)
├─ Five hbrtl (483 standard RTL functions)
├─ hbrtl_ext/httpserver — HTTP server RTL
├─ hbrtl_ext/capi — bridge_*.prg helpers
├─ hbrtl_ext/pgrtl — PostgreSQL client RTL
├─ app/ — bridge_*.prg + app PRG
└─ go:embed — static assets
fnode build api/*.prg --extra-rtl=hbrtl_ext/... -o myapp produces a
self-contained binary. No external dependencies beyond what the app code
itself opens (e.g. a Postgres connection).
Build
go build -o fnode ./cmd/fnode
./fnode build app/hello.prg -o hello
./hello
