<HelloProvider/>

By default, clicking the Hellō button would redirect to /api/hellocoop?op=login endpoint with the optional properties as additional query parameters. To override this behavior, wrap your app with the <HelloProvider/> component and pass the config object as a prop to the provider.

App.svelte
<script>
    import { HelloProvider } from '@hellocoop/svelte';
 
    //default
    const config = {
        login: '/api/hellocoop?op=login'
    }
</script>
 
<HelloProvider {config}>
    <main> 
    ...
    </main>
</HelloProvider>
