Package Exports

memoizee-proxy

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (memoizee-proxy) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Memoize based on Proxy.

features

Works with any type, any length of function arguments - optional serialization.

Cache can be managed manually.
Cache size can be limited on LRU basis.
Optional reference counter mode, that allows more sophisticated cache management.
unit tests.

API

Property	Description	Type	Default
normalizer	Generates a unique value based on the current parameter	(args: any[]) => string	Array.from(argument).join(',')
weak	Using WeakMap	boolean	false
maxAge	Timeout duration, expired delete	number	undefined
max	Maximum number of items stored	number	undefined
manual	Enable manage the cache manually	boolean	false
refCounter	Enable reference counting	boolean	false

Installation

npm install memoizee-proxy

yarn add memoizee-proxy

Usage

import {memoizee} from 'memoizee-proxy'

var fn = function(one, two, three) {
  /* ... */
};

var memoized = memoizee(fn);

memoized("foo", 3, "bar");
memoized("foo", 3, "bar"); // Cache hit

var afn = function(a, b) {
    return new Promise(function(res) {
        res(a + b);
    });
};
memoized = memoize(afn, { promise: true });

memoized(3, 7);
memoized(3, 7); // Cache hit
