The optimistic Connecting paint and the Idle/stale-Connected
suppression lived in the tray's applyStatus, so only the tray got the
smoothed-out transition during a profile switch — the React Status
page (useStatus hook in frontend) subscribes to the same
netbird:status event and was seeing the raw daemon stream, complete
with the Disconnected blink.
Move the policy one layer up into the Peers service, between
SubscribeStatus and the Wails event bus, so every consumer downstream
sees the same filtered stream:
* Peers gains BeginProfileSwitch / CancelProfileSwitch / shouldSuppress.
BeginProfileSwitch sets the in-progress flag and emits a synthetic
Connecting status so both the tray and React paint Connecting
immediately. shouldSuppress swallows the daemon's stale Connected
(peer-count teardown) and transient Idle (Down between flows)
until Connecting / NeedsLogin / LoginFailed / SessionExpired /
DaemonUnavailable indicates the new profile's flow has started,
or a 30s safety timeout fires.
* ProfileSwitcher.SwitchActive calls peers.BeginProfileSwitch when
wasActive (prevStatus was Connected or Connecting) — the only
cases where the daemon emits the blink-inducing sequence. Other
prevStatuses already terminate cleanly on Idle.
* Tray loses its switchInProgress fields, applyOptimisticConnecting
helper, applyStatus suppression switch, and switchProfile's
optimistic-paint call. handleDisconnect now calls
Peers.CancelProfileSwitch alongside cancelling switchCancel, so
the abort path bypasses the suppression filter and the daemon's
Idle paints through immediately.
The full prevStatus -> action / optimistic label / suppressed events
matrix now lives in the ProfileSwitcher struct godoc, with the
suppression-rule-per-incoming-status table on the Peers struct
godoc — together they describe the click-time policy and the
stream-filter behaviour without duplication.
Wails bindings need regenerating to pick up Peers.BeginProfileSwitch
and Peers.CancelProfileSwitch.
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.
