@idxdb/promised/dist/src/shared/request-resolver.js

@idxdb/promised wraps the IndexedDB API. It allows you to easily store and retrieve data in an indexed db database using async/await syntax, making it easier to integrate with your existing codebase.

export const requestResolver = (request) => new Promise((resolve, reject) => {
    const onsuccess = (event) => {
        request.removeEventListener('success', onsuccess);
        request.removeEventListener('error', onerror);
        const target = event.target;
        resolve(target.result);
    };
    /* istanbul ignore next */
    const onerror = (event) => {
        request.removeEventListener('success', onsuccess);
        request.removeEventListener('error', onerror);
        const target = event.target;
        reject(target.error);
    };
    request.addEventListener('success', onsuccess);
    request.addEventListener('error', onerror);
});
