Different ways to call an ES6 class that is bundled in the <script> tag

Currently, I am utilizing Webpack to transpile my ES6 classes. Within the bundle, there is a Service class that can be imported by other bundled scripts.

class Service {
    constructor() {
        //
    }

    someMethod(data) {
        //
    }
}

export default Service;

Now, I have a small inline script in the HTML body (pseudo-code provided below), which needs to invoke a method in the Service class with data inserted server-side via a template engine like Twig or Blade. Naturally, creating a new instance of the Service won't suffice...

<body>
    ...
    <script>
        var data = {{ $json_server_data }}; 

        var service = new Service;

        Service.someMethod(data);
    </script>
</body>

I am keen on having the server data readily available inline to avoid an extra asynchronous call. The idea of cluttering the window namespace with the Service class seems counterproductive considering the advantages of a class loader...

How do you propose dealing with this? Any suggestions for alternative approaches are appreciated as well.

Answer №1

If you want your Service class to be accessible outside of the bundled javascript scope, you'll need to make it global by attaching it to the window object. Here's how you can do that:

// Service.js
class Service {
    constructor() {
        // Constructor code here
    }

    someMethod(data) {
        // Method implementation here
    }
}

window.Service = Service;

export default Service;


// Usage
let myService = new Service();
