CacheCraft

CacheCraft is a TypeScript-based caching library that provides a collection of classes to easily memorize and cache the results of function calls. It offers a variety of caching mechanisms including simple key-value mapping, list-based caching, and weak reference caching.

Features

• Memorizer: Simple key-value caching.
• MemorizerList: Caching for list-like data structures.
• WeakMemorizer: WeakMap-based caching for objects.
• LastKnownMemorizer: Caches the last known value.

Installation

npm install cachecraft

or

yarn add cachecraft

Usage

Memorizer

import { Memorizer } from 'cachecraft';

const memo = new Memorizer<number, string>((value) => value.toString());
console.log(memo.get(1)); // "1"

MemorizerList

import { MemorizerList } from 'cachecraft';

const memoList = new MemorizerList<number, string>((value) => value.toString());
console.log(memoList.get(1)); // "1"

WeakMemorizer

import { WeakMemorizer } from 'cachecraft';

const weakMemo = new WeakMemorizer<object, string>((value) => JSON.stringify(value));
const obj = { key: 'value' };
console.log(weakMemo.get(obj)); // "{"key":"value"}"

LastKnownMemorizer

import { LastKnownMemorizer } from 'cachecraft';

const lastKnownMemo = new LastKnownMemorizer<number, string>((value) => value.toString());
console.log(lastKnownMemo.get(1)); // "1"

Custom Comparers

You can also specify custom comparers for MemorizerList and LastKnownMemorizer:

import { MemorizerList, LastKnownMemorizer } from 'cachecraft';

const customComparer = (a: number, b: number) => a % 10 === b % 10;

const memoList = new MemorizerList<number, string>((value) => value.toString(), customComparer);
const lastKnownMemo = new LastKnownMemorizer<number, string>((value) => value.toString(), customComparer);
