The Profiles and Exit Node submenus (and the About version/Update rows) stopped reflecting changes on KDE/Plasma: after the first profile switch the menu froze on its initial snapshot, and "Manage Profiles" — plus the profile rows themselves — stopped responding to clicks entirely. Root cause (confirmed via dbus-monitor): Plasma's StatusNotifierItem host caches a submenu's layout the first time it is opened (GetLayout for that submenu id) and never re-fetches it on a LayoutUpdated(parent=0) signal. The old submenu.Clear()+Add() repaint allocated fresh monotonic item ids each time but reused the same submenu container id, so Plasma kept showing the stale snapshot and, on click, sent the stale ids back — which the rebuilt itemMap no longer knew, silently no-op'ing the click. Fix: route every dynamic tray-menu change through a new relayoutMenu that rebuilds the whole tree (buildMenu + repaint cached state + a single SetMenu), allocating brand-new submenu container ids. Plasma treats those as unseen and re-queries them on next open, fixing both the stale paint and the dead clicks. loadProfiles/refreshExitNodes now cache their rows and drive relayoutMenu; the update row goes through a new onMenuChange hook; the daemon-version row relayouts too. relayoutMenu is serialised by menuMu and the fill*Submenu helpers are pure UI (no fetch, no SetMenu) so it never recurses. The whole-tree SetMenu also subsumes the prior darwin detached-NSMenu workaround.
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) wails3CLI:go install github.com/wailsapp/wails/v3/cmd/wails3@latesttask:go install github.com/go-task/task/v3/cmd/task@latest- A running NetBird daemon (default:
unix:///var/run/netbird.sock, Windowstcp://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.
