SvelteKit submission pattern

Keep your existing SvelteKit page/form components.

Submit directly to the Formsig endpoint for centralized handling.

Use progressive enhancement on the frontend while keeping backend simple.

Why this helps

Avoid repetitive form action handlers across routes.

Send accepted submissions into webhook-driven workflows quickly.

Maintain one consistent intake layer for different product surfaces.

Production notes

Use environment-based endpoint config for local/dev/prod parity.

Set anti-abuse protections for public traffic.

Treat webhook retries as normal and design idempotent receivers.

Frequently asked questions

Can this work with SvelteKit form actions?

Yes. You can mix approaches and use Formsig for forms where centralized intake is preferred.

Is this only for static SvelteKit deployments?

No. The same Formsig endpoint model works for static and server-hosted SvelteKit apps.
