Overview

Build, debug, and package Wails v3 desktop apps (module github.com/wailsapp/wails/v3, a prerelease) that pair a Go backend with a web frontend: application.New and its Options, services registered with application.NewService and their startup and shutdown hooks, bindings from wails3 generate bindings, errors and panics as rejected promises, typed events, dialogs, windows, embedded assets, the wails3 CLI and Taskfile, server mode, and cgo with GTK4 and WebKitGTK 6.0 on Linux. Use when writing or changing a Wails v3 app, adding a service method, or debugging a v3 build, binding, or blank window. Not for Wails v2 (module github.com/wailsapp/wails/v2; use the wails2 skill), Electron or Tauri apps, or Go web servers.

Wails v3

Wails v3 runs a Go backend and a web frontend in native windows. You create the app with application.New, register Go structs as services, open windows through app.Window, and reach dialogs and events through managers on the app (app.Dialog, app.Event). The exported methods of each service become promise-returning functions in generated TypeScript or JavaScript. v3 is a prerelease, its API changes between betas, and it shares almost no API with v2, so most bugs come from code written for v2 or for a different beta.

Workflow

Read go.mod. If it requires github.com/wailsapp/wails/v2, stop and use the wails2 skill; without it, read the pinned v2 module source. v2 and v3 APIs do not mix, so do not migrate between majors, or move to another v3 beta, unless asked. If the project pins a v3 version other than the one in Sources, read that version's source before trusting a detail here: go doc github.com/wailsapp/wails/v3/pkg/application, or the module cache under $(go env GOMODCACHE)/github.com/wailsapp/wails/v3@<version>.
Find application.New(application.Options{...}), the services, the windows, the //go:embed asset directory, and how the project builds: Taskfile.yml with the wails3 CLI, or plain go build from a script. Keep the existing workflow.
Change the Go side first, following The service contract. For generated bindings, the JavaScript runtime, and frontend tests, see references/frontend.md.
For build tags, cgo, Linux libraries, the Taskfile, and server mode, see references/building.md.
Before finishing, run Verify.

Telling v3 from v2

Concern	Wails v3	Wails v2 (never in v3 code)
Entry point	`application.New(application.Options{...})`, then `app.Run()`	`wails.Run(&options.App{...})`
Exposing Go	`Services: []application.Service{application.NewService(&T{})}`	`Bind: []any{&T{}}`
Lifecycle	`ServiceStartup(ctx, application.ServiceOptions) error` and `ServiceShutdown() error` on the service; `Options.OnShutdown`	`OnStartup`, `OnDomReady`, `OnShutdown`, `OnBeforeClose` in `options.App`
Runtime calls	`app.Event.Emit`, `app.Dialog.SaveFile()`, `app.Window.NewWithOptions`	`runtime.EventsEmit(ctx, ...)`, `runtime.SaveFileDialog(ctx, ...)`
Frontend	`frontend/bindings/<import path>/` and `@wailsio/runtime`	`wailsjs/go/...` and `window.go`
Tooling	`wails3` CLI, `Taskfile.yml`, `build/config.yml`	`wails` CLI, `wails.json`
Linux	`gtk4` and `webkitgtk-6.0`; `-tags gtk3` for GTK3	`gtk+-3.0` and `webkit2gtk-4.0` or `-4.1`

Imports from github.com/wailsapp/wails/v2/..., a runtime. call that takes a context, or a wailsjs path in a v3 project is a mixing mistake.

The service contract

Keep each service thin, its exported methods the whole frontend API, and everything native behind an interface the tests can replace:

// examples/wails3/notes/service.go (trimmed: storage and the other methods omitted)
type Native interface {
	SaveFile(defaultName string) (string, error) // "" when cancelled
	Emit(event string, data any)
}

type Service struct {
	mu     sync.Mutex // bound calls can run concurrently
	notes  []Note
	native Native
}

func NewService(native Native) *Service { return &Service{native: native} }

func (s *Service) SaveNote(in NoteInput) (Note, error) {
	in, err := validate(in)
	if err != nil {
		return Note{}, err // rejects the frontend promise
	}
	return s.store(Note(in)) // locks s.mu and emits EventNotesChanged
}

The app wires it up in main:

// examples/wails3/main.go (trimmed: init, window size, Mac options, Emit, and the file filter omitted)
// assets is the //go:embed all:frontend/dist filesystem (see Assets below).
func main() {
	app := application.New(application.Options{
		Name:   "Notes",
		Assets: application.AssetOptions{Handler: application.AssetFileServerFS(assets)},
	})
	app.RegisterService(application.NewService(notes.NewService(desktop{app})))
	app.Window.NewWithOptions(application.WebviewWindowOptions{Title: "Notes", URL: "/"})
	if err := app.Run(); err != nil {
		log.Fatal(err)
	}
}

// desktop implements notes.Native; the service's tests use a fake instead.
type desktop struct{ app *application.App }

func (d desktop) SaveFile(name string) (string, error) {
	return d.app.Dialog.SaveFile().SetFilename(name).PromptForSingleSelection()
}

Both blocks are trimmed from complete files that build and pass their tests: examples/wails3/main.go and examples/wails3/notes/service.go. Copy those for a runnable starting point; the desktop build needs cgo (see references/building.md).

application.NewService takes a pointer to a named, non-generic struct. Register one instance per type, in Options.Services or with app.RegisterService before Run. A service registered after Run starts is dropped and the error goes to Options.ErrorHandler.
Every exported method on the pointer type is a binding, except ServiceName, ServiceStartup, ServiceShutdown, and ServeHTTP. v2's exemption for methods passed as lifecycle hooks does not exist, so an exported Startup or Shutdown method is callable from JavaScript. Keep helpers unexported and wiring in plain functions.
Return T, error, or (T, error); several non-error results arrive as an array. A non-nil error rejects the promise with a RuntimeError whose message is err.Error(). When the error value marshals to JSON, that JSON becomes the rejection's cause; Options.MarshalError or ServiceOptions.MarshalError changes it. Arguments that do not decode reject with a TypeError. A panic rejects that call and the app keeps running.
Arguments and results cross as JSON. Give every field an explicit json tag; an untagged field keeps its Go name and json:"-" drops it. A nil slice is null on the wire, so return an empty slice.
A first parameter of type context.Context is filled in by Wails and left out of the generated signature. Wails cancels it when the frontend cancels the promise, and it carries the calling window under application.WindowKey.
Validate input again in Go: any script in the webview can call a binding. Calls from a webview run on their own goroutines and overlap, so guard shared state with a mutex.
A service can implement two optional lifecycle hooks:
```
// excerpt: optional lifecycle hooks (pkg/application/services.go)
func (s *Service) ServiceStartup(ctx context.Context, opts application.ServiceOptions) error
func (s *Service) ServiceShutdown() error
```
ServiceStartup runs in registration order before windows open; its context is cancelled before shutdown, and a returned error makes Run return it. ServiceShutdown runs in reverse order.
application.New returns the first App on every later call. Build it once in main.

Events, dialogs, and windows

Register each custom event once, in init, by calling application.RegisterEvent with the payload type T as its type argument and the event name (see examples/wails3/main.go). The generator then writes TypeScript types for them, and app.Event.Emit checks the data type exactly: a *T for a T event is reported to ErrorHandler and cancelled. Events the frontend emits arrive in Go decoded into T.
app.Event.On returns a function that removes the listener. Use method results for request and response, and events for progress or pushed state.
Dialogs come from app.Dialog: SaveFile(), OpenFile(), and message dialogs (Info, Question, Warning, Error). A cancelled file dialog returns "" (multiple selection: nil) and a nil error; treat that as "nothing happened".
app.Window.NewWithOptions opens a window; call it again for more. Windows created before Run open when it starts. Give each a Name and find it later with app.Window.GetByName. Menus and the system tray hang off app.Menu and app.SystemTray.

Assets

//go:embed all:frontend/dist with application.AssetFileServerFS(assets) serves the built frontend; the asset server finds index.html below the embed root, so fs.Sub is not needed. Build the frontend before go build. In v3 a missing index.html does not stop startup: every request fails with a 500 that says "no index.html could be found", which shows as a blank or error window. The app serves its JavaScript runtime at /wails/runtime.js.

Verify

Before finishing, run go vet ./... and go test ./... for the changed packages, and check:

no v2 import, type, or runtime call appears in the change;
invalid input to each changed binding returns an error and changes nothing;
a cancelled dialog writes nothing and returns no error;
native calls go through an interface faked in tests;
bindings were regenerated with the project's wails3 version and build tags, not edited, and the frontend type checks against them; the handoff names the command (wails3 generate bindings with its flags, or the Taskfile task) so the user can rerun it after the next service change;
the frontend build is fresh, so index.html is in the embedded assets;
the native build succeeds with the project's tags when Wails integration changed.

When a check fails, match the symptom in references/building.md or the sections above, fix it, and rerun every check. Server mode and browser tests do not exercise WebKitGTK, WebKit, WebView2, native dialogs, or window lifecycle; where a desktop session is available, launch the built app, and state in the handoff what native behavior was not exercised.

Sources

Verified against Wails v3.0.0-beta.29, a prerelease. Each stated behavior has a test or a source citation in the examples module. When the project's version differs, trust its module source over this skill.

## Telling v3 from v2

| Concern | Wails v3 | Wails v2 (never in v3 code) |
| --- | --- | --- |
| Entry point | `application.New(application.Options{...})`, then `app.Run()` | `wails.Run(&options.App{...})` |

| Linux | `gtk4` and `webkitgtk-6.0`; `-tags gtk3` for GTK3 | `gtk+-3.0` and `webkit2gtk-4.0` or `-4.1` |

Imports from `github.com/wailsapp/wails/v2/...`, a `runtime.` call that
takes a context, or a `wailsjs` path in a v3 project is a mixing mistake.

## The service contract

Keep each service thin, its exported methods the whole frontend API, and
everything native behind an interface the tests can replace:

```go
// examples/wails3/notes/service.go (trimmed: storage and the other methods omitted)
type Native interface {
	SaveFile(defaultName string) (string, error) // "" when cancelled
	Emit(event string, data any)
}

type Service struct {
	mu     sync.Mutex // bound calls can run concurrently
	notes  []Note
	native Native
}

func NewService(native Native) *Service { return &Service{native: native} }

func (s *Service) SaveNote(in NoteInput) (Note, error) {
	in, err := validate(in)
	if err != nil {
		return Note{}, err // rejects the frontend promise
	}
	return s.store(Note(in)) // locks s.mu and emits EventNotesChanged
}
```

The app wires it up in `main`:

```go
// examples/wails3/main.go (trimmed: init, window size, Mac options, Emit, and the file filter omitted)
// assets is the //go:embed all:frontend/dist filesystem (see Assets below).
func main() {
	app := application.New(application.Options{
		Name:   "Notes",
		Assets: application.AssetOptions{Handler: application.AssetFileServerFS(assets)},
	})
	app.RegisterService(application.NewService(notes.NewService(desktop{app})))
	app.Window.NewWithOptions(application.WebviewWindowOptions{Title: "Notes", URL: "/"})
	if err := app.Run(); err != nil {
		log.Fatal(err)
	}
}

// desktop implements notes.Native; the service's tests use a fake instead.
type desktop struct{ app *application.App }

func (d desktop) SaveFile(name string) (string, error) {
	return d.app.Dialog.SaveFile().SetFilename(name).PromptForSingleSelection()
}
```

Both blocks are trimmed from complete files that build and pass their tests:
[`examples/wails3/main.go`](https://github.com/tpscloud/gophers/blob/main/examples/wails3/main.go)
and
[`examples/wails3/notes/service.go`](https://github.com/tpscloud/gophers/blob/main/examples/wails3/notes/service.go).
Copy those for a runnable starting point; the desktop build needs cgo (see
[references/building.md](references/building.md)).

- `application.NewService` takes a pointer to a named, non-generic struct.
  Register one instance per type, in `Options.Services` or with
  `app.RegisterService` before `Run`. A service registered after `Run` starts
  is dropped and the error goes to `Options.ErrorHandler`.
- Every exported method on the pointer type is a binding, except
  `ServiceName`, `ServiceStartup`, `ServiceShutdown`, and `ServeHTTP`.
  v2's exemption for methods passed as lifecycle hooks does not exist, so an
  exported `Startup` or `Shutdown` method is callable from JavaScript. Keep
  helpers unexported and wiring in plain functions.
- Return `T`, `error`, or `(T, error)`; several non-error results arrive as
  an array. A non-nil error rejects the promise with a `RuntimeError` whose
  message is `err.Error()`. When the error value marshals to JSON, that JSON
  becomes the rejection's `cause`; `Options.MarshalError` or
  `ServiceOptions.MarshalError` changes it. Arguments that do not decode
  reject with a `TypeError`. A panic rejects that call and the app keeps
  running.
- Arguments and results cross as JSON. Give every field an explicit `json`
  tag; an untagged field keeps its Go name and `json:"-"` drops it. A nil
  slice is `null` on the wire, so return an empty slice.
- A first parameter of type `context.Context` is filled in by Wails and left
  out of the generated signature. Wails cancels it when the frontend cancels
  the promise, and it carries the calling window under
  `application.WindowKey`.
- Validate input again in Go: any script in the webview can call a binding.
  Calls from a webview run on their own goroutines and overlap, so guard
  shared state with a mutex.
- A service can implement two optional lifecycle hooks:

  ```go
  // excerpt: optional lifecycle hooks (pkg/application/services.go)
  func (s *Service) ServiceStartup(ctx context.Context, opts application.ServiceOptions) error
  func (s *Service) ServiceShutdown() error
  ```

  `ServiceStartup` runs in registration order before windows open; its
  context is cancelled before shutdown, and a returned error makes `Run`
  return it. `ServiceShutdown` runs in reverse order.
- `application.New` returns the first `App` on every later call. Build it
  once in `main`.

## Events, dialogs, and windows

- Register each custom event once, in `init`, by calling
  `application.RegisterEvent` with the payload type `T` as its type argument
  and the event name (see `examples/wails3/main.go`). The generator then writes TypeScript types for them, and `app.Event.Emit`
  checks the data type exactly: a `*T` for a `T` event is reported to
  `ErrorHandler` and cancelled. Events the frontend emits arrive in Go
  decoded into `T`.
- `app.Event.On` returns a function that removes the listener. Use method
  results for request and response, and events for progress or pushed state.
- Dialogs come from `app.Dialog`: `SaveFile()`, `OpenFile()`, and message
  dialogs (`Info`, `Question`, `Warning`, `Error`). A cancelled file dialog
  returns `""` (multiple selection: `nil`) and a nil error; treat that as
  "nothing happened".
- `app.Window.NewWithOptions` opens a window; call it again for more. Windows
  created before `Run` open when it starts. Give each a `Name` and find it
  later with `app.Window.GetByName`. Menus and the system tray hang off
  `app.Menu` and `app.SystemTray`.

## Assets

`//go:embed all:frontend/dist` with
`application.AssetFileServerFS(assets)` serves the built frontend; the asset
server finds `index.html` below the embed root, so `fs.Sub` is not needed.
Build the frontend before `go build`. In v3 a missing `index.html` does not
stop startup: every request fails with a 500 that says "no `index.html` could
be found", which shows as a blank or error window. The app serves its
JavaScript runtime at `/wails/runtime.js`.

## Verify

Before finishing, run `go vet ./...` and `go test ./...` for the changed
packages, and check:

- no v2 import, type, or runtime call appears in the change;
- invalid input to each changed binding returns an error and changes nothing;
- a cancelled dialog writes nothing and returns no error;
- native calls go through an interface faked in tests;
- bindings were regenerated with the project's `wails3` version and build
  tags, not edited, and the frontend type checks against them; the handoff
  names the command (`wails3 generate bindings` with its flags, or the
  Taskfile task) so the user can rerun it after the next service change;
- the frontend build is fresh, so `index.html` is in the embedded assets;
- the native build succeeds with the project's tags when Wails integration
  changed.

When a check fails, match the symptom in
[references/building.md](references/building.md) or the sections above, fix
it, and rerun every check. Server mode and browser tests do not exercise
WebKitGTK, WebKit, WebView2, native dialogs, or window lifecycle; where a
desktop session is available, launch the built app, and state in the handoff
what native behavior was not exercised.
