var cache = require('halfexpired-lru');
 
cache.set('a',1);
 
cache.get('a',function(err,key,value,ttl,remaining){
  if(err == 'halfexpired') {
    request(url,function(err,data){
      if(err) {
    // if i set it halfexpired will hit next in half the remaining time.
    cache.set(key,value,remaining);
    console.log('that flakey api failed again! good thing my value is not completely expired ;)');
      } else cache.set(key,value,ttl);
    })
  }
});
