hurryup v0.0.8

HurryUp is a timeout library for asynchronous, fault-prone function calls. Basically, it'll timeout an async call if it's been running for too long. You can also specify to re-call async functions until they succeed (see below).

What can you use it for?

• db operations
• api calls
• async jobs

hurryUp(asyncCallback, optionsOrTimeout, ...args)

• asyncCallback - async function to call
• optionsOrTimeout
  • object - options passed
    • retry - TRUE if the timedCallback should be re-called if it returns an error
    • retryTimeout - timeout between retrying timed callback
    • timeout - kill timeout
  • number - the timeout before killing the function call
• ...args - additional arguments to pass to the async callback

hurryUp(function(next) {
  
  //this will cause an error
  setTimeout(next, 2000);
}, 1000).call(null, function(err, result) {
  console.error("timeout has occurred!")
})

Here's an easier way to wrap around a method:

hurryUp(emitter.once, 1000).call(emitter, "connected", function(err, result) {
  
});

You can also use hurryup to run a callback multiple times until it succeeds, like so:

function isItReady(next) {
  //async stuff here
  next(new Error("no!"));
}

hurryUp(function(next) {
  isItReady(next);
}, { retry: true }).call(null, function(err) {
  console.log(err.message); //no!
});
