FrailMap

FrailMap is an extension of WeakMap that supports primitive values using WeakRef. It may also set individual pairs to be strongly referenced when specified, or when WeakRef is not available.

Usage

import { FrailMap } from "frail-map";

const myMap = new FrailMap<string, number>();
myMap.set("foo", "foo");
myMap.set("bar", "bar", { strong: true });

console.log(myMap.get("foo")); // -> "foo"
console.log(myMap.get("bar")); // -> "bar"

// ... After GC ...

console.log(myMap.get("foo")); // -> undefined
console.log(myMap.get("bar")); // -> "bar"
