ShallowMemoize

Memoization with ability to set cache size and use shallow comparison.

Usage

import memoize from 'shallow-memoize'

let memoizeOptions = {
  cacheSize: 1, // size of cache, should be greater than 0. Default is Infinity.
  useShallowCompare: true, // whether shallow compare should be used. Default is false.
};

let add = memoize(function(a, b) {
  return a.val + b.val;
}, memoizeOptions);

add({ val: 5 }, { val: 5 });
add({ val: 5 }, { val: 5 }); // cache hit

add({ val: 3 }, { val: 3 });
add({ val: 3 }, { val: 3 }); // cache hit

add({ val: 5 }, { val: 5 }); // no cache, because cache size is 1
