expire-set

expire-set is a package that is basically a set - only that its values expire after a certain set time.

Usage

Just use it as if you would be using a normal set:

const ExpireSet = require("expire-set");
const timeout = 10000; // 10 seconds
const set = new ExpireSet(timeout);
set.add("fox");
console.log(set.has("fox")); // outputs true
setTimeout(() => {
	console.log(set.has("fox")); // outputs false
}, timeout + 6); // the library needs some time to do its magic

You can also use it with typescript:

import ExpireSet from "expire-set";
const timeout = 10000; // 10 seconds
const set = new ExpireSet<string>(timeout);
set.add("blah");
set.delete("blah");

Methods

The following methods exist:

• set.size: Returns the size of the ExpiredSet
• set.all: Returns the ExpiredSet as a normal Set
• set.add(value): Adds a value to the ExpiredSet, returning itself
• set.has(value): Returns true/false, if the ExpiredSet has the value
• set.delete(value): Deletes a value of the ExpiredSet, returning itself
