Create AMP-Compatible Site in Svelte

You can make your SvleteKit site AMP-compatible by setting amp to true in your svelte.config.js file, like this:

kit: {
    amp: true,
    ...
},
...

Please note that you might want to avoid setting amp to true unless absolutely necessary, because client-side JavaScript (and client-side routing) will be disabled completely.

The AMP boilerplate styles will be automatically injected, and the development server will let you know if the AMP validator picks up any errors as you are building and testing your site.

Conclusion

Anyway, that’s how you go about making your SvelteKit site AMP-friendly. But again, I’d suggest avoiding this unless you are certain that you really need AMP support.
