Function cacheIt

cacheIt<T>(obj, options?): CachedFunction<T>

make all methods of object are cached

Type Parameters

T extends GeneralFunction

Parameters

obj: T
Optionaloptions: CacheItOptions<any>

Returns CachedFunction<T>

Since

5.16.0

Example


   // set max cache size
   const f = cacheIt((value: number) => (++idx) + value, {
     providerOptions: {
       params: {
         max_entries: 2
       }
     }
   });
   expect(f.__cache_storage["_maxSize"]).toBe(2);

   expect(f(0)).toBe(1);
   expect(f(0)).toBe(1);

cacheIt<T>(obj, options?): CachedClass<T>

create a class wrapper, the instance created by that wrapper will automatically apply cacheIt

Type Parameters

T extends Class

Parameters

obj: T
Optionaloptions: CacheItOptions<any>

Returns CachedClass<T>

Since

5.16.0

Example

 class A {
     constructor(idx = 0) { this.idx = idx; }
     private idx: number
     public add(value: number) {
       return (++this.idx) + value;
     }
   }
   const CachedA = cacheIt(A);
   const a = new CachedA(1);
   expect(a.add(0)).toBe(2);
   expect(a.add(0)).toBe(2);

   expect(a.add(1)).toBe(4);
   expect(a.add(1)).toBe(4);
