co-waiter

co-waiter

Super-simple wait() function which is a lightweight wrapper around setTimeout. I wrote this module just so I'd have an easy way to use things like yield wait.seconds(30); in my co-based workflows.

Provides the following methods. Each waits an amount of time, then resolves a promise. If the v argument is passed, the promise will resolve with that value.

• wait(n,v) -- milliseconds
• wait.until(date, v) -- wait until date, then resolve. if date is in the past, resolve immediately.
• wait.seconds(n,v)
• wait.second(n,v)
• wait.sec(n,v)
• wait.minutes(n,v)
• wait.minute(n,v)
• wait.min(n,v)
• wait.hours(n,v)
• wait.hour(n,v)
• wait.days(n,v)
• wait.day(n,v)
• wait.weeks(n,v)
• wait.week(n,v)
• wait.months(n,v)
• wait.month(n,v)

install

npm install --save co-waiter

quick examples:

var wait = require('co-waiter');

var delayed = wait.minutes(30, "something");
delayed.then(function(value) {
  console.log("this is", value, "30 minutes too late :(");
});

co(function*() {
  var val = yield wait.sec(3.5, 7);
  return val;
}).then(function(value) {
  console.log(value + "after 3.5 seconds");
});

somePromise.then(function(val) {
  return wait.until(someDate, val);
}).then(function(x) {
  console.log(x, "took a long time to get here!");
});

co(function*() {
  var val = yield someAsyncCall();
  val = yield wait.minute(Math.PI, val);
  return val;
}).then(function(myVal) {
  console.log(myVal + " after π seconds");
});
