Drawing creation handler

This example demonstrates how the

onDrawingNew

callback sends a request using the Fetch API to create new drawings and their associated layouts. Once the request completes, the result is returned to the widget through the

onResponse

callback.

Drawing creation handler

onDrawingNew = async function(drawings: Array<DIQ_DrawingRevision>, layouts: Array<DIQ_Layout>, onResponse: (result: DIQ_Result) => void) {
    try {
        const res = await fetch("/api/drawings", {
            method: "POST",
            headers: {
                "Content-Type": "application/json"
            },
            body: JSON.stringify({
                drawing,
                layouts
            })
        });

        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 drawing"
        });
    }
};
