Dimension update handler

This example demonstrates how the

onDimensionUpdate

callback sends a request using the Fetch API to update an existing dimension. Once the request completes, the result is returned to the widget through the

onResponse

callback.

Dimension update handler

const onDimensionUpdate = async function (dimension: DIQ_Dimension, onResponse: (result: DIQ_Result) => void) {
    try {
        const res = await fetch("/api/dimensions", {
            method: "PUT",
            headers: {
                "Content-Type": "application/json"
            },
            body: JSON.stringify(dimension)
        });

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

        await res.json();

        onResponse({ ok: true });

    } catch (err: any) {
        onResponse({
            ok: false,
            message: err.message || "Failed to update dimension"
        });
    }
};
