better-cooldown

A simple cooldown checker.

Latest version introduces breaking changes.

Usage

Use createCooldown() function to create a cooldown tracker.

Then use the tick() function to know how much time (in ms) until the function can be used next. If the function can be used at the time of using tick function, it will return 0.

Note: limit is the amount of times a cooldown can be used in specified period.

Note: period must be in seconds

Basic Example

let limit = 2;
let period = 15; // default: 60

let commandCooldown = createCooldown(limit, period);
// In this example, cooldown is 2 times in 15 seconds.

console.log(commandCooldown.tick());
// expected output: 0

console.log(commandCooldown.tick());
// expected output: 0

console.log(commandCooldown.tick());
// expected output: approx. 14990

// 10 seconds after initial tick
console.log(commandCooldown.tick());
// expected output: approx. 4990

// 15 seconds after initial tick
console.log(commandCooldown.tick());
// expected output: 0

Detailed

{
    limit: number,
    period: number,
    strikes: number[],
