Zoltan Papp 0fe8764707 [client/ui] Optimistic Connecting on profile switch, status row disabled
Three UX fixes for the tray's profile-switch flow:

* Optimistic Connecting paint when switching from Connected/Connecting.
  Previously the daemon's Down step emitted Idle before the new
  profile's Up emitted Connecting, leaving the tray flashing
  "Disconnected" for the duration of the Down. switchProfile now sets a
  flag and synthesizes a Connecting paint at click time; applyStatus
  suppresses the transient Idle and the stale Connected updates that
  arrive during the old profile's teardown, clearing the flag only when
  the new profile's flow surfaces (Connecting, NeedsLogin, LoginFailed,
  SessionExpired, DaemonUnavailable, or a 30s safety timeout).

* Disconnect during an in-flight switch now actually disconnects. The
  switchCancel context cancels the ProfileSwitcher.SwitchActive
  goroutine so its queued Up RPC never fires, and the
  switchInProgress flag is cleared so the daemon's Idle push paints
  through immediately. Without this, the user's Disconnect click was
  followed seconds later by the switcher's Up bringing the new
  profile back online.

* The first menu row is informational only. SetEnabled(false) is
  re-applied to t.statusItem (initial build, applyStatus, and the
  optimistic paint) and the openRoute("/login") OnClick handler is
  dropped — every actionable transition flows through the
  Connect/Disconnect entries below.

The switchProfile and applyStatus godocs carry the full
prevStatus → suppressed-events / final-state transition tables so
future readers don't have to rebuild the policy from the code.

NetBird desktop UI (Wails3 + React)

Replaces client/ui (Fyne). One binary on Windows / macOS / Linux, talks to the NetBird daemon over gRPC, renders a React frontend in a WebView.

Prerequisites

  • Go ≥ 1.25, Node ≥ 20, pnpm (corepack enable && corepack prepare pnpm@latest --activate)
  • wails3 CLI: go install github.com/wailsapp/wails/v3/cmd/wails3@latest
  • task: go install github.com/go-task/task/v3/cmd/task@latest
  • A running NetBird daemon (default: unix:///var/run/netbird.sock, Windows tcp://127.0.0.1:41731)
  • Linux only: libwebkit2gtk-4.1-dev, libgtk-3-dev, libayatana-appindicator3-dev

Develop without rebuilding

cd client/ui
task dev

task dev runs Vite (port 9245) + the Go binary + a *.go watcher. Frontend edits hot-reload instantly. Go edits trigger a rebuild and relaunch. Pass daemon flags after --:

task dev -- --daemon-addr=tcp://127.0.0.1:41731

For pure UI work (no native window, fastest loop):

cd frontend && pnpm dev

Production build

task build

Output in bin/. Frontend assets are embedded into the binary.

Cross-compile Windows from Linux

Install the mingw-w64 toolchain once:

sudo apt install gcc-mingw-w64-x86-64           # Debian/Ubuntu
sudo dnf install mingw64-gcc                    # Fedora
sudo pacman -S mingw-w64-gcc                    # Arch

Then:

CGO_ENABLED=1 task windows:build

Produces bin/netbird-ui.exe. macOS cross-compile from Linux is not supported (signing and notarization need a real Mac).

Windows console build (logs in the terminal)

Default windows:build links the binary as a Windows GUI app, which detaches from the launching console — logrus output, fmt.Println, and panics go nowhere visible. To debug tray/event/daemon issues:

CGO_ENABLED=1 task windows:build:console

Produces bin/netbird-ui-console.exe. Run it from cmd.exe / PowerShell / Windows Terminal and stdout/stderr land in that terminal. Same flag works on a native Windows build (drop the CGO_ENABLED=1 if your toolchain already has it set).

Regenerating bindings

When a Go service signature changes:

wails3 generate bindings

task dev does this automatically on *.go save.

Tray icons

Source SVGs live in assets/svg/ (state.svg + state-macos.svg). After editing any SVG, rasterize to the PNGs the Go side embeds:

task common:generate:tray:icons

Requires Inkscape. Commit the resulting assets/*.png files alongside the SVG change so CI doesn't need Inkscape installed.
