--------------------------------

### Call New Go Service Method from Frontend

Source: https://v3alpha.wails.io/quick-start/first-app

Implement frontend logic to call the newly added Go service method, passing necessary arguments and handling the returned data.

```javascript
window.greetMany = async () => {
    const names = ['Alice', 'Bob', 'Charlie'];
    const greetings = await GreetService.GreetMany(names);
    console.log(greetings);
};

```

```

--------------------------------

### Register Go Service with Wails Application

Source: https://v3alpha.wails.io/quick-start/first-app

Register your Go service struct with the Wails application in `main.go` to make its methods available to the frontend.

```go
err := application.New(application.Options{
    Name: "myapp",
    Services: []application.Service{
        application.NewService(&GreetService{}),
    },
    // ... other options
})

```

--------------------------------

### Call Go Service Method from Frontend JavaScript

Source: https://v3alpha.wails.io/quick-start/first-app

Import the auto-generated service bindings and call Go methods asynchronously. Handle potential errors using try/catch blocks.

```javascript
import {GreetService} from "../bindings/changeme";


window.greet = async () => {
    const nameElement = document.getElementById('name');
    const resultElement = document.getElementById('result');


    const name = nameElement.value;
    if (!name) {
        return;
    }


    try {
        const result = await GreetService.Greet(name);
        resultElement.innerText = result;
    } catch (err) {
        console.error(err);
    }
};

```

--------------------------------

### Add New Method to Go Service

Source: https://v3alpha.wails.io/quick-start/first-app

Extend your Go service by adding new exported methods. Wails will automatically detect these changes during development.

```go
func (g *GreetService) GreetMany(names []string) []string {
    greetings := make([]string, len(names))
    for i, name := range names {
        greetings[i] = fmt.Sprintf("Hello %s!", name)
    }
    return greetings
}

```

--------------------------------

### Reload Shell Configuration
