Revision creation handler​

This example demonstrates how the

onRevisionNew
callback sends a request using the Fetch API to create a new revision. Once the request completes, the result is returned to the widget through the

onResponse
callback.
TypeScript
Revision creation handler
onRevisionNew = async function(revision: DIQ_Revision, onResponse: (result: DIQ_Result) => void ) {
    try {
        const res = await fetch("/api/revisions", {
            method: "POST",
            headers: {
                "Content-Type": "application/json"
            },
            body: JSON.stringify(revision)
        });

        if (!res.ok) {
            throw new Error(`HTTP ${res.status}`);
        }

        await res.json();

        onResponse({ ok: true });

    } catch (err) {
        onResponse({
            ok: false,
            message: err.message || "Failed to create revision"
        });
    }
};
