Installation

Add the plugin to the Plugins option in the Applications options. This example we are using the github provider:

package main

import (
    "github.com/wailsapp/wails/v3/pkg/application"
    "github.com/wailsapp/wails/v3/plugins/browser"
)

func main() {
    oAuthPlugin := oauth.NewPlugin(oauth.Config{
        Providers: []goth.Provider{
            github.New(
                os.Getenv("clientkey"),
                os.Getenv("secret"),
                "http://localhost:9876/auth/github/callback",
                "email",
                "profile"),
        },
    })

    app := application.New(application.Options{
    // ...
    Plugins: map[string]application.Plugin{
        "oauth": oAuthPlugin,
    },
})

Configuration

The plugin takes a Config struct as a parameter. This struct has the following fields:

type Config struct {

    // Address to bind the temporary webserver to
    // Defaults to localhost:9876
    Address string
    
    // SessionSecret is the secret used to encrypt the session store.
    SessionSecret string
    
    // MaxAge is the maximum age of the session in seconds.
    MaxAge int
    
    // Providers is a list of goth providers to use.
    Providers []goth.Provider
    
    // WindowConfig is the configuration for the window that will be opened
    // to perform the OAuth login.
    WindowConfig *application.WebviewWindowOptions
}

If you don't specify a WindowConfig, the plugin will use the default window configuration:

&application.WebviewWindowOptions{
    Title:  "OAuth Login",
    Width:  600,
    Height: 850,
    Hidden: true,
}

Usage

Go

You can start the flow by calling one of the provider methods:

err := oAuthPlugin.Github()

In this example, we send an event from the frontend to start the process, so we listen for the event in the backend:

app.Events.On("github-login", func(e *application.WailsEvent) {
    err := oAuthPlugin.Github()
    if err != nil {
        // process error
    }
})

JavaScript

You can start the flow by calling one of the provider methods:

await wails.Plugin("oauth","Github")

Handling Success & Failure

When the OAuth flow completes, the plugin will send one of 2 events:

- `wails:oauth:success` - The OAuth flow completed successfully. The event data will contain the user information.
- `wails:oauth:error` - The OAuth flow failed. The event data will contain the error message.

In Javascript, we can listen for these events like so:

window.wails.Events.On("wails:oauth:success", (event) => {
    document.getElementById("main").style.display = "none";
    document.getElementById("name").innerText = event.data.Name;
    document.getElementById("logo").src = event.data.AvatarURL;
    document.body.style.backgroundColor = "#000";
    document.body.style.color = "#FFF";
});

If you want to handle them in Go, you can do so like this:

app.Events.On("wails:oauth:success", func(e *application.WailsEvent) {
    // Do something with the user data
})

Both these events are constants in the plugin:

const (
    Success = "wails:oauth:success"
    Error   = "wails:oauth:error"
)

There is a working example of GitHub auth in the v3/examples/oauth directory.

Logging Out

To log out, you can call the relevant Logout method for the provider:

    err := oAuthPlugin.GithubLogout()

On success, the plugin will send a wails:oauth:loggedout event. On failure, it will send a wails:oauth:error event.
