JS Timing

Utility library for handling time and timing.

Usage

Most of the functions in this library rely on a single main type, Duration. To create a duration, use the duration method:

import {duration, HOUR, SECONDS} from "@prodo-ai/js-timing";
 
const tenSeconds = duration(10, SECONDS);
const oneHour = duration(1, HOUR);

You can then modify durations, or convert them to different units:

const threeHours = oneHour.times(3);
 
const waitInMinutes = (numMinutes: number) => {/*...*/};
waitInMinutes(oneHour.in(MINUTES));

waitFor

Returns a Promise that will return after a provided duration;

import {waitFor} from "@prodo-ai/js-timing";
 
waitFor(duration(10, SECONDS)).then(() => console.log("Done."));

repeatedly

Runs a callback again and again. The optional second parameter specifies how much delay should be included between each execution:

import {repeatedly} from "@prodo-ai/js-timing";
 
const callback = () => {
  console.log("foo")
};
 
const cancel = repeatedly(callback);
waitFor(duration(10, SECONDS)).then(cancel);
 
const cancel2 = repeatedly(callback, duration(1, SECOND));
waitFor(duration(10, SECONDS)).then(cancel2);

You can control the duration between each execution by returning a Duration from your callback - the execution of the next callback will only happen after that duration has passed:

const callback = () => {
  console.log("foo");
  return duration(1, SECOND);
};
const cancel = repeatedly(callback);
 
waitFor(duration(10, SECONDS)).then(cancel); // The callback will executed

You can also specify an error handler:

const callback = () => {
  throw new Error("Failed.");
};
const errorHandler = (error) => {
  console.error(error.message);
};
const cancel = repeatedly(callback, duration(1, MILLISECOND), errorHandler);

every

Actually, this is just the same as repeatedly.
