Simple Node.js expiration helper

$ npm install expires
var expires = require('expires');
 
// Returns some timestamp like 1341151672247 
var timestamp = expires.after('2 seconds');
 
// Then it can be tested for expiration 
expires.expired(timestamp);  // false 
setTimeout(function() {
    expires.expired(timestamp);  // true 
}, 2500);
  • "ms", "millisecond(s)"
  • "sec(s)", "second(s)"
  • "min(s)", "minute(s)"
  • "hr(s)", "hour(s)"
  • "day(s)"
  • "wk(s)", "week(s)"
  • "yr(s)", "year(s)"

Also completely valid are fractional values, such as the following:

expires.after('0.5 hours');
expires.after('1/2 hours');
 
// A bit extreme, but still valid 
expires.after('2.3/4.5 hours');
