Javascript Readable SetTimeout

Create setTimeouts using readable timeout strings.

Imagine we could declare timeouts like this

setTimeout(() => false, "next 10 seconds");
// or
setTimeout(() => false, "30 seconds from now");
//
setTimeout(() => false, "in 1 hour 30 minutes from now");

Well, thanks to chrono-node and some magic lines of voodoo this package is able to achieve that but of course not with same default setTimeout function.

Installation

npm i readable-timeout
# OR
yarn add readable-timeout

Usage

const Timeout = require('readable-timeout');

Timeout.define(() => false, "next 30 seconds");
// is equivalent to
Timeout.run(() => false, "next 30 seconds"); // allias of define
// is equivalent to
setTimeout(() => false, 30000) // 3000±1
// is equivalent to
Timeout.run(() => false, 30000) 
// milliseconds can also be used but defeats the purpose of this package

Note: All setTimeouts returns the timeout as the default setTimeout would.

.in

The .in method gives you the freedom of declaring timeouts first if you find it easier to read.

const Timeout = require('readable-timeout');

Timeout.in("30 seconds", () => false);

Utils

The class also includes functions that converts strings to milliseconds

.ms

This function converts a string to milliseconds or throws an error if it can't.

const Timeout = require('readable-timeout');

Timeout.ms("next 5 seconds"); // 5000±1000

.msIn

Same as ms but used in .in, Adds from now to the end of your text. This is because chrono-node needs it to understand simple non-sentence strings like "30 seconds"

const Timeout = require('readable-timeout');

Timeout.msIn("5 seconds"); // 5000±1000
// is transformed to
Timeout.ms("5 seconds from now");

Performance

If you are extremely Performance conscious then you should use the default setTimeout because it would take a very tiny millisecond to understand your string and convert to milliseconds.

Accuracy

Returned milliseconds is not exactly the number you are expecting, most times maybe ±1000ms. You can Run tests to see what we mean. E.g.

const Timeout = require('readable-timeout');

// you would expect this to return 10000
Timeout.msIn("10 seconds");
// what maybe returned
// Between [9000-11000]

This only means a lot when you want the exact seconds
