Dimensions creation handler

This example demonstrates how the

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

onResponse
callback.

TypeScript
Dimensions creation handler
const onDimensionsNew = async function (dimensions: Array<DIQ_Dimension>, onResponse: (result: DIQ_Result) => void) {
try {
const res = await fetch("/api/dimensions", {
method: "POST",
headers: {
"Content-Type": "application/json"
},
body: JSON.stringify({ dimensions })
});

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 create dimensions"
});
}
};
