Revision listing handler

This example demonstrates how the

onListRevisions

callback sends a request using the Fetch API to retrieve revisions for a project. Once the request completes, the result and returned revisions are provided to the widget through the

onResponse

callback.

Revision listing handler

onListRevisions = async function (project: DIQ_Project, onResponse: (result: DIQ_Result, revisions: Array<DIQ_Revision> | null ) => void) {
    try {
        const res = await fetch(`/api/projects/${project.key}/revisions`, {
            method: "GET",
            headers: {
                "Content-Type": "application/json"
            }
        });

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

        const revisions: DIQ_Revision[] = await res.json();

        // Successful response
        onResponse({ ok: true }, revisions);

    } catch (err) {
        // Error response
        onResponse({
            ok: false,
            message: err.message || "Failed to fetch revisions"
        }, null);
    }
};
