Project close handler​

This example demonstrates how the

onProjectClose
callback sends a request using the Fetch API to close the current project. Once the request completes, the result is returned to the widget through the

onResponse
callback.
TypeScript
Project close handler
onProjectClose = async function(onResponse: (result: DIQ_Result) => void) {
    try {
        const res = await fetch("/api/project/close", {
            method: "POST"
        });

        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 close project"
        });
    }
};
