Set timeouts that survive restarts, persisted with leveldb.
In the example below, a timer is set 60 seconds from now. This timer will survive restarts of the script.
var db = getLevelUpSomehow();
var pt = persistentTimeout(db, ontimeout);
pt.timeout(Date.now() + 60000, {foo: 'bar'}); // 60 seconds
function ontimeout (data) {
console.log(data);
}MIT
