• File hub/driver.go — part of check-in [0fa13d595b] at 2026-05-13 21:03:54 on branch trunk — fix: exclude modernc driver registration from wasm builds (#169)

  The init()-based modernc registration added in #166 (v0.0.18) blocked wasm builds because modernc references syscalls unavailable under js/wasm. Adds a //go:build !js && !wasm constraint to hub/driver.go so the registration is skipped on wasm targets — wasm consumers register their own driver (libfossil's ncruces driver supports wasm via its ncruces_js.go file).

  Native builds are unchanged: hub still auto-registers modernc. Wasm builds: hub package now compiles successfully under GOOS=js GOARCH=wasm; consumer brings its own driver.

  Verified: GOOS=js GOARCH=wasm go vet ./hub/... # clean GOOS=js GOARCH=wasm go build ./hub/... # success go test ./hub/... -timeout 120s # 38/38 pass on native

//go:build !js && !wasm

package hub

// libfossil's db layer requires a SQL driver to be registered before any
// Repo can be opened. Registering it here means consumers of EdgeSync can
// `import "github.com/danmestas/EdgeSync/hub"` without also taking a direct
// dependency on libfossil's internal SQL machinery — the package doc
// promise that consumers don't need to import libfossil holds end-to-end.
//
// modernc is a pure-Go cgo-free SQLite driver suitable for every supported
// GOOS/GOARCH except js/wasm — its generated code references unsupported
// syscalls under those targets. The build constraint above excludes this
// file from wasm compilation; wasm consumers must register their own
// driver (libfossil's ncruces driver has wasm support via ncruces_js.go).
