fetchAPIにタイムアウトがないのでawaitしたときに死ぬからつらい

FetchWithTimeout.ts

new Promise(async(resolve, reject) => {
    let timeoutHendle = setTimeout(() => {
        reject();
    }, 5000);

    let response: Response = null;
    if (init == null) {
        response = await fetch(input);
    } else {
        response = await fetch(input, init);
    }

    clearTimeout(timeoutHendle);
    resolve(response);
});
