The default Windows build links the binary as a GUI subsystem app, so stdout/stderr is detached from the launching terminal — invisible logrus output makes tray and event-stream bugs hard to chase. Add a sibling task that links as console subsystem and writes a separately-named binary so the production output is preserved. Usage: CGO_ENABLED=1 task windows:build:console bin\netbird-ui-console.exe # logs print to the launching cmd/PowerShell

# 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
|
|
|
|
```bash
|
|
cd client/ui-wails
|
|
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 `--`:
|
|
|
|
```bash
|
|
task dev -- --daemon-addr=tcp://127.0.0.1:41731
|
|
```
|
|
|
|
For pure UI work (no native window, fastest loop):
|
|
|
|
```bash
|
|
cd frontend && pnpm dev
|
|
```
|
|
|
|
## Production build
|
|
|
|
```bash
|
|
task build
|
|
```
|
|
|
|
Output in `bin/`. Frontend assets are embedded into the binary.
|
|
|
|
### Cross-compile Windows from Linux
|
|
|
|
Install the mingw-w64 toolchain once:
|
|
|
|
```bash
|
|
sudo apt install gcc-mingw-w64-x86-64 # Debian/Ubuntu
|
|
sudo dnf install mingw64-gcc # Fedora
|
|
sudo pacman -S mingw-w64-gcc # Arch
|
|
```
|
|
|
|
Then:
|
|
|
|
```bash
|
|
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:
|
|
|
|
```bash
|
|
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:
|
|
|
|
```bash
|
|
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:
|
|
|
|
```bash
|
|
task common:generate:tray:icons
|
|
```
|
|
|
|
Requires Inkscape. Commit the resulting `assets/*.png` files alongside the
|
|
SVG change so CI doesn't need Inkscape installed.
