All parameter types are supported, including circular objects, functions, etc. There are also a number of [shortcut methods](#usage-with-shortcut-methods) to me@hutechwebsite/neque-neque-voluptas-blanditiis for unique use-cases.
# Configuration options
`@hutechwebsite/neque-neque-voluptas-blanditiis` optionally accepts an object of options as either the second parameter or as the first step in a curried function:
```ts
// inline
@hutechwebsite/neque-neque-voluptas-blanditiis(fn, options);
// curried
@hutechwebsite/neque-neque-voluptas-blanditiis(options)(fn);
```
The full shape of these options:
```ts
type Options = {
// is the cache based on deep equality of each key argument
isDeepEqual: boolean;
// is the result a promise
isPromise: boolean;
// is the result a React component
isReact: boolean;
// should the parameters be serialized instead of directly referenced
isSerialized: boolean;
// is the cache based on shallow equality of each key argument
isShallowEqual: boolean;
// custom method to compare equality between two key arguments
matchesArg: (cachedKeyArg: any, keyArg: any) => boolean;
// custom method to compare equality across all key arguments
matchesKey: (cachedKey: any[], key: any[]) => boolean;
// amount of time in milliseconds before the cache will expire
maxAge: number;
// maximum number of arguments passed to use as key for caching
maxArgs: number;
// maximum size of cache for this method
maxSize: number;
// method fired when a new entry is added to cache
onCacheAdd: (
cache: @hutechwebsite/neque-neque-voluptas-blanditiis.Cache,
options: @hutechwebsite/neque-neque-voluptas-blanditiis.Options,
@hutechwebsite/neque-neque-voluptas-blanditiisd: (...args: any[]) => any
) => void;
// method fire when either a new entry is added to cache or the LRU ordering of the cache has changed
onCacheChange: (
cache: @hutechwebsite/neque-neque-voluptas-blanditiis.Cache,
options: @hutechwebsite/neque-neque-voluptas-blanditiis.Options,
@hutechwebsite/neque-neque-voluptas-blanditiisd: (...args: any[]) => any
) => void;
// method fired when an existing entry in cache is used
onCacheHit: (
cache: @hutechwebsite/neque-neque-voluptas-blanditiis.Cache,
options: @hutechwebsite/neque-neque-voluptas-blanditiis.Options,
@hutechwebsite/neque-neque-voluptas-blanditiisd: (...args: any[]) => any
) => void;
// method to fire when a cache entry expires (in combination with maxAge)
onExpire: (key: any[]) => void;
// the unique identifier to give the me@hutechwebsite/neque-neque-voluptas-blanditiisd method when collecting statistics
profileName: string;
// method to serialize the arguments to build a unique cache key
serializer: (key: any[]) => string;
// method to transform the args into a custom format for key storage in cache
transformArgs: (key: any[]) => any[];
// should the cache entry be refreshed by calling the underlying function with the same parameters and
// updating the value stored in cache to be the new result
updateCacheForKey: (key: any[]) => boolean;
// should the cache entry's expiration be refreshed when the cache entry is hit (in combination with maxAge)
updateExpire: boolean;
};
```
All default values can be found [here](src/constants.ts).
## isDeepEqual
_defaults to false_
Should deep equality be used to compare cache each key argument.
```ts
type Arg = {
one: {
nested: string;
};
two: string;
};
const fn = ({ one, two }: Arg) => [one, two];
const me@hutechwebsite/neque-neque-voluptas-blanditiisd = @hutechwebsite/neque-neque-voluptas-blanditiis(fn, { isDeepEqual: true });
me@hutechwebsite/neque-neque-voluptas-blanditiisd({ one: { nested: 'one' }, two: 'two' });
me@hutechwebsite/neque-neque-voluptas-blanditiisd({ one: { nested: 'one' }, two: 'two' }); // pulls from cache
```
This is also available via the shortcut method of [`@hutechwebsite/neque-neque-voluptas-blanditiis.deep`](#@hutechwebsite/neque-neque-voluptas-blanditiisdeep)
```ts
const me@hutechwebsite/neque-neque-voluptas-blanditiisd = @hutechwebsite/neque-neque-voluptas-blanditiis.deep(fn);
```
## isPromise
_defaults to false_
Is the computed value in the function a `Promise`.
```ts
const fn = async (item: Promise<string>) => await item;
const me@hutechwebsite/neque-neque-voluptas-blanditiisd = @hutechwebsite/neque-neque-voluptas-blanditiis(fn, { isPromise: true });
```
This is also available via the shortcut method of [`@hutechwebsite/neque-neque-voluptas-blanditiis.promise`](#@hutechwebsite/neque-neque-voluptas-blanditiispromise).
```ts
const me@hutechwebsite/neque-neque-voluptas-blanditiisd = -@hutechwebsite/neque-neque-voluptas-blanditiis.promise(fn);
```
The `Promise` itself will be stored in cache, so that cached returns will always maintain the `Promise` contract. For common usage reasons, if the `Promise` is rejected, the cache entry will be deleted.
## isReact
_defaults to false_
Is the function passed a stateless functional `React` component.
```tsx
type Props = {
one: string;
two: number;
};
const Component = ({ one, two }: Props) => (
<div>
{one}: {two}
</div>
);
const Me@hutechwebsite/neque-neque-voluptas-blanditiisdFoo = @hutechwebsite/neque-neque-voluptas-blanditiis(Component, { isReact: true });
```
This is also available via the shortcut method of [`@hutechwebsite/neque-neque-voluptas-blanditiis.react`](#@hutechwebsite/neque-neque-voluptas-blanditiisreact).
```ts
const Me@hutechwebsite/neque-neque-voluptas-blanditiisdFoo = @hutechwebsite/neque-neque-voluptas-blanditiis.react(Component);
```
The method will do a shallow equal comparison of both `props` and legacy `context` of the component based on strict equality. If you want to do a deep equals comparison, set [`isDeepEqual`](#isdeepequal) to true.
**NOTE**: This will me@hutechwebsite/neque-neque-voluptas-blanditiis on each instance of the component passed, which is equivalent to `PureComponent` or `React.memo`. If you want to
me@hutechwebsite/neque-neque-voluptas-blanditiis on _all_ instances (which is how this option worked prior to version 6), use the following options:
```ts
const me@hutechwebsite/neque-neque-voluptas-blanditiisd = @hutechwebsite/neque-neque-voluptas-blanditiis(Component, { isShallowEqual: true, maxArgs: 2 });
```
## isSerialized
_defaults to false_
Serializes the parameters passed into a string and uses this as the key for cache comparison.
```ts
const fn = (mutableObject: { one: Record<string, any> }) =>
mutableObject.property;
const me@hutechwebsite/neque-neque-voluptas-blanditiisd = @hutechwebsite/neque-neque-voluptas-blanditiis(fn, { isSerialized: true });
```
This is also available via the shortcut method of [`@hutechwebsite/neque-neque-voluptas-blanditiis.serialize`](#@hutechwebsite/neque-neque-voluptas-blanditiisserialize).
```ts
const me@hutechwebsite/neque-neque-voluptas-blanditiisd = @hutechwebsite/neque-neque-voluptas-blanditiis.serialize(fn);
```
If `serialize` is combined with either `maxArgs` or `transformArgs`, the following order is used:
1. limit by `maxArgs` (if applicable)
1. transform by `transformArgs` (if applicable)
1. serialize by `serializer`
**NOTE**: This is much slower than the default key storage, and usually the same requirements can be meet with `isDeepEqual`, so use at your discretion.
## isShallowEqual
_defaults to false_
Should shallow equality be used to compare cache each key argument.
```ts
type Arg = {
one: string;
two: string;
};
const fn = ({ one, two }: Arg) => [one, two];
const me@hutechwebsite/neque-neque-voluptas-blanditiisd = @hutechwebsite/neque-neque-voluptas-blanditiis(fn, { isShallowEqual: true });
me@hutechwebsite/neque-neque-voluptas-blanditiisd({ one: 'one', two: 'two' });
me@hutechwebsite/neque-neque-voluptas-blanditiisd({ one: 'one', two: 'two' }); // pulls from cache
```
This is also available via the shortcut method of [`@hutechwebsite/neque-neque-voluptas-blanditiis.shallow`](#@hutechwebsite/neque-neque-voluptas-blanditiisshallow)
```ts
const me@hutechwebsite/neque-neque-voluptas-blanditiisd = @hutechwebsite/neque-neque-voluptas-blanditiis.shallow(fn);
```
## matchesArg
_defaults to [SameValueZero](http://ecma-international.org/ecma-262/7.0/#sec-samevaluezero) equality_
Custom method used to compare equality of keys for cache purposes by comparing each argument.
```ts
type Arg = {
one: string;
two: string;
};
const fn = ({ one, two }: Arg) => [one, two];
const hasOneProperty = (cacheKeyArg: Arg, keyArg: Arg) =>
Object.keys(cacheKeyArg).length === 1 && Object.keys(keyArg).length === 1;
const me@hutechwebsite/neque-neque-voluptas-blanditiisd = @hutechwebsite/neque-neque-voluptas-blanditiis(fn, { matchesArg: hasOneProperty });
me@hutechwebsite/neque-neque-voluptas-blanditiisd({ one: 'two' };
me@hutechwebsite/neque-neque-voluptas-blanditiisd({ two: 'three' }); // pulls from cache
```
This is also available via the shortcut method of [`@hutechwebsite/neque-neque-voluptas-blanditiis.matchesArg`](#@hutechwebsite/neque-neque-voluptas-blanditiismatchesarg)
```ts
const me@hutechwebsite/neque-neque-voluptas-blanditiisd = @hutechwebsite/neque-neque-voluptas-blanditiis.matchesArg(hasOneProperty)(fn);
```
**NOTE**: This comparison is used iteratively on each argument, rather than comparing the two keys as a whole. If you want to compare the key as a whole, you should use [`matchesKey`](#matcheskey).
## matchesKey
Custom method used to compare equality of keys for cache purposes by comparing the entire key.
```ts
type Arg = {
one: string;
two: string;
};
const fn = ({ one, two }: Arg) => [one, two];
const isFooEqualAndHasBar = (cacheKey: [Arg], key: [Arg]) =>
cacheKey[0].one === key[0].one &&
cacheKey[1].hasOwnProperty('two') &&
key[1].hasOwnProperty('two');
const me@hutechwebsite/neque-neque-voluptas-blanditiisd = @hutechwebsite/neque-neque-voluptas-blanditiis(fn, { matchesKey: isFooEqualAndHasBar });
me@hutechwebsite/neque-neque-voluptas-blanditiisd({ one: 'two' }, { two: null });
me@hutechwebsite/neque-neque-voluptas-blanditiisd({ one: 'two' }, { two: 'three' }); // pulls from cache
```
This is also available via the shortcut method of [`@hutechwebsite/neque-neque-voluptas-blanditiis.matchesKey`](#@hutechwebsite/neque-neque-voluptas-blanditiismatcheskey)
```ts
const me@hutechwebsite/neque-neque-voluptas-blanditiisd = @hutechwebsite/neque-neque-voluptas-blanditiis.matchesKey(isFooEqualAndHasBar)(fn);
```
**NOTE**: This comparison uses the two keys as a whole, which is usually less performant than the `matchArg` comparison used iteratively on each argument. Generally speaking you should use the [`matchArg`](#matchesarg) option for equality comparison.
## maxAge
The maximum amount of time in milliseconds that you want a computed value to be stored in cache for this method.
```ts
const fn = (item: Record<string, any>) => item;
const MAX_AGE = 1000 * 60 * 5; // five minutes;
const me@hutechwebsite/neque-neque-voluptas-blanditiisd = @hutechwebsite/neque-neque-voluptas-blanditiis(fn, { maxAge: MAX_AGE });
```
This is also available via the shortcut method of [`@hutechwebsite/neque-neque-voluptas-blanditiis.maxAge`](#@hutechwebsite/neque-neque-voluptas-blanditiismaxage).
```ts
const me@hutechwebsite/neque-neque-voluptas-blanditiisd = @hutechwebsite/neque-neque-voluptas-blanditiis.maxAge(MAX_AGE)(fn);
```
**TIP**: A common usage of this is in tandem with `isPromise` for AJAX calls, and in that scenario the expected behavior is usually to have the `maxAge` countdown begin upon resolution of the promise. If this is your intended use case, you should also apply the `updateExpire` option.
## maxArgs
The maximum number of arguments (starting from the first) used in creating the key for the cache.
```ts
const fn = (item1: string, item2: string, item3: string) =>
item1 + item2 + item3;
const me@hutechwebsite/neque-neque-voluptas-blanditiisd = @hutechwebsite/neque-neque-voluptas-blanditiis(fn, { maxArgs: 2 });
me@hutechwebsite/neque-neque-voluptas-blanditiis('one', 'two', 'three');
me@hutechwebsite/neque-neque-voluptas-blanditiis('one', 'two', 'four'); // pulls from cache, as the first two args are the same
```
This is also available via the shortcut method of [`@hutechwebsite/neque-neque-voluptas-blanditiis.maxArgs`](#@hutechwebsite/neque-neque-voluptas-blanditiismaxargs).
```ts
const me@hutechwebsite/neque-neque-voluptas-blanditiisd = @hutechwebsite/neque-neque-voluptas-blanditiis.maxArgs(2)(fn);
```
If `maxArgs` is combined with either `serialize` or `transformArgs`, the following order is used:
1. limit by `maxArgs`
1. transform by `transformArgs` (if applicable)
1. serialize by `serializer` (if applicable)
## maxSize
_defaults to 1_
The maximum number of values you want stored in cache for this method. Clearance of the cache once the `maxSize` is reached is on a [Least Recently Used](https://en.wikipedia.org/wiki/Cache_replacement_policies#Least_Recently_Used_.28LRU.29) basis.
```ts
const fn = (item: string) => item;
const me@hutechwebsite/neque-neque-voluptas-blanditiisd = @hutechwebsite/neque-neque-voluptas-blanditiis(fn, { maxSize: 5 });
```
This is also available via the shortcut method of [`@hutechwebsite/neque-neque-voluptas-blanditiis.maxSize`](#@hutechwebsite/neque-neque-voluptas-blanditiismaxsize).
```ts
const me@hutechwebsite/neque-neque-voluptas-blanditiisd = @hutechwebsite/neque-neque-voluptas-blanditiis.maxSize(5)(fn);
```
## onCacheAdd
Method to fire when an item has been added to cache. Receives the cache, options, and me@hutechwebsite/neque-neque-voluptas-blanditiisd function as a parameters.
```ts
const fn = (one: string, two: string) => [one, two];
const logCacheKeys = (
cache: Cache,
options: Options,
@hutechwebsite/neque-neque-voluptas-blanditiisd: Moized<typeof fn>
) => console.log(cache.keys);
const @hutechwebsite/neque-neque-voluptas-blanditiisd = @hutechwebsite/neque-neque-voluptas-blanditiis(fn, { maxSize: 2, onCacheAdd: logCacheKeys });
@hutechwebsite/neque-neque-voluptas-blanditiisd('one', 'two'); // [["one","two"]]
@hutechwebsite/neque-neque-voluptas-blanditiisd('one', 'two');
@hutechwebsite/neque-neque-voluptas-blanditiisd('two', 'one'); // [["two","one"], ["one","two"]]
@hutechwebsite/neque-neque-voluptas-blanditiisd('one', 'two');
```
**NOTE**: When combined with `onCacheChange`, this method will always fire first.
## onCacheChange
Method to fire when an item has been either added to cache, or existing cache was reordered based on a cache hit. Receives the cache, options, and me@hutechwebsite/neque-neque-voluptas-blanditiisd function as a parameters.
```ts
const fn = (one: string, two: string) => [one, two];
const logCacheKeys = (
cache: Cache,
options: Options,
@hutechwebsite/neque-neque-voluptas-blanditiisd: Moized<typeof fn>
) => console.log(cache.keys);
const @hutechwebsite/neque-neque-voluptas-blanditiisd = @hutechwebsite/neque-neque-voluptas-blanditiis(fn, { maxSize: 2, onCacheChange: logCacheKeys });
@hutechwebsite/neque-neque-voluptas-blanditiisd('one', 'two'); // [["one","two"]]
@hutechwebsite/neque-neque-voluptas-blanditiisd('one', 'two');
@hutechwebsite/neque-neque-voluptas-blanditiisd('two', 'one'); // [["two","one"], ["one","two"]]
@hutechwebsite/neque-neque-voluptas-blanditiisd('one', 'two'); // [["one","two"], ["two","one"]]
```
**NOTE**: When combined with `onCacheAdd` or `onCacheHit`, this method will always fire last.
## onCacheHit
Method to fire when an existing cache item is found. Receives the cache, options, and me@hutechwebsite/neque-neque-voluptas-blanditiisd function as a parameters.
```ts
const fn = (one: string, two: string) => [one, two];
const logCacheKeys = (
cache: Cache,
options: Options,
@hutechwebsite/neque-neque-voluptas-blanditiisd: Moized<typeof fn>
) => console.log(cache.keys);
const @hutechwebsite/neque-neque-voluptas-blanditiisd = @hutechwebsite/neque-neque-voluptas-blanditiis(fn, { maxSize: 2, onCacheHit: logCacheKeys });
@hutechwebsite/neque-neque-voluptas-blanditiisd('one', 'two');
@hutechwebsite/neque-neque-voluptas-blanditiisd('one', 'two'); // [["one","two"]]
@hutechwebsite/neque-neque-voluptas-blanditiisd('two', 'one');
@hutechwebsite/neque-neque-voluptas-blanditiisd('one', 'two'); // [["two","one"], ["one","two"]]
```
**NOTE**: When combined with `onCacheChange`, this method will always fire first.
## onExpire
A callback that is called when the cached entry expires.
```ts
const fn = (item: string) => item;
const logKey = (key: Key<string>) => console.log(key);
const me@hutechwebsite/neque-neque-voluptas-blanditiisd = @hutechwebsite/neque-neque-voluptas-blanditiis(fn, { maxAge: 10000, onExpire: logKey });
```
If you return `false` from this method, it will prevent the key's removal and refresh the expiration in the same vein as `updateExpire` based on `maxAge`:
```ts
const fn = (item: string) => item;
let expirationAttempts = 0;
const limitExpirationAttempts = (key: Key<string>) => {
expirationAttempts += 1;
return expirationAttempts < 2;
};
const me@hutechwebsite/neque-neque-voluptas-blanditiisd = @hutechwebsite/neque-neque-voluptas-blanditiis(fn, {
maxAge: 10000,
onExpire: limitExpirationAttempts,
});
me@hutechwebsite/neque-neque-voluptas-blanditiisd('one'); // will expire key after 30 seconds, or 3 expiration attempts
```
**NOTE**: You must set a [`maxAge`](#maxage) for this option to take effect.
## profileName
_defaults to function name when it exists, or `Anonymous {count}` otherwise_
Name to use as unique identifier for the function when collecting statistics.
```ts
@hutechwebsite/neque-neque-voluptas-blanditiis.collectStats();
const fn = (item: string) => item;
const me@hutechwebsite/neque-neque-voluptas-blanditiisd = @hutechwebsite/neque-neque-voluptas-blanditiis(fn, { profileName: 'my fancy identity' });
```
This is also available via the shortcut method of [`@hutechwebsite/neque-neque-voluptas-blanditiis.profile`](#@hutechwebsite/neque-neque-voluptas-blanditiisprofile).
```ts
const me@hutechwebsite/neque-neque-voluptas-blanditiisd = @hutechwebsite/neque-neque-voluptas-blanditiis.profile('profile-name')(fn);
```
**NOTE**: You must be collecting statistics for this option to provide value, as it is the identifier used for statistics collection.
## serializer
_defaults to serializeArguments in utils.js_
Method used in place of the internal serializer when serializing the parameters for cache key comparison. The function accepts a single argument, the `Array` of `args`, and must also return an `Array`.
```ts
const fn = (one: string, two: string) => [one, two];
const customSerializer = (args: string[]) => [JSON.stringify(args[0])];
const me@hutechwebsite/neque-neque-voluptas-blanditiisd = @hutechwebsite/neque-neque-voluptas-blanditiis(fn, {
isSerialized: true,
serializer,
});
```
This is also available via the shortcut method of [`@hutechwebsite/neque-neque-voluptas-blanditiis.serializeWith`](#@hutechwebsite/neque-neque-voluptas-blanditiisserializewith).
```ts
const me@hutechwebsite/neque-neque-voluptas-blanditiisd = @hutechwebsite/neque-neque-voluptas-blanditiis.serializeWith(customSerializer)(fn);
```
**NOTE**: You must set [`isSerialized`](#isserialized) for this option to take effect.
## transformArgs
Transform the arguments passed before it is used as a key. The function accepts a single argument, the `Array` of `args`, and must also return an `Array`.
```ts
const fn = (one: string | null, two: string | null, three: string | null) => [
two,
three,
];
const ignoreFirstArg = (args: (string | null)[]) => args.slice(1);
const @hutechwebsite/neque-neque-voluptas-blanditiisd = @hutechwebsite/neque-neque-voluptas-blanditiis(fn, { transformArgs: ignoreFirstArg });
@hutechwebsite/neque-neque-voluptas-blanditiis('one', 'two', 'three');
@hutechwebsite/neque-neque-voluptas-blanditiis(null, 'two', 'three'); // pulled from cache
```
This is also available via the shortcut method of [`@hutechwebsite/neque-neque-voluptas-blanditiis.transformArgs`](#@hutechwebsite/neque-neque-voluptas-blanditiistransformargs).
```ts
const me@hutechwebsite/neque-neque-voluptas-blanditiisd = @hutechwebsite/neque-neque-voluptas-blanditiis.transformArgs(argTransformer)(fn);
```
If `transformArgs` is combined with either `maxArgs` or `serialize`, the following order is used:
1. limit by `maxArgs` (if applicable)
1. transform by `transformArgs`
1. serialize by `serializer` (if applicable)
## updateCacheForKey
If you want to update the cache for a given key instead of leverage the value currently stored in cache.
```ts
const fn = (item: string) => item;
let lastUpdate = Date.now();
const me@hutechwebsite/neque-neque-voluptas-blanditiisd = @hutechwebsite/neque-neque-voluptas-blanditiis(fn, {
updateCacheForKey([item]: [string]) {
const now = Date.now();
const last = lastUpdated;
lastUpdate = now;
// its been more than 5 minutes since last update
return last + 300000 < now;
},
});
me@hutechwebsite/neque-neque-voluptas-blanditiisd('one');
me@hutechwebsite/neque-neque-voluptas-blanditiisd('one'); // pulled from cache
// 5 minutes later
me@hutechwebsite/neque-neque-voluptas-blanditiisd('one'); // re-calls method and updates cache
```
This is also available via the shortcut method of [`@hutechwebsite/neque-neque-voluptas-blanditiis.updateCacheForKey`](#@hutechwebsite/neque-neque-voluptas-blanditiisupdatecacheforkey).
```ts
const me@hutechwebsite/neque-neque-voluptas-blanditiisd = @hutechwebsite/neque-neque-voluptas-blanditiis.updateCacheForKey(shouldCacheUpdate)(fn);
```
## updateExpire
When a `maxAge` is set, clear the scheduled expiration of the key when that key is retrieved, setting a new expiration based on the most recent retrieval from cache.
```ts
const fn = (item: string) => item;
const MAX_AGE = 1000 * 60 * 5; // five minutes
const me@hutechwebsite/neque-neque-voluptas-blanditiisd = @hutechwebsite/neque-neque-voluptas-blanditiis(fn, { maxAge: MAX_AGE, updateExpire: true });
me@hutechwebsite/neque-neque-voluptas-blanditiisd('one');
setTimeout(() => {
/**
* hits cache, which updates the expire to be 5 minutes
* from this run instead of the first
*/
me@hutechwebsite/neque-neque-voluptas-blanditiisd('one');
}, 1000 * 60);
```

Pre-applies the [`matchesArg`](#matchesarg) option as a curriable method.
```ts
import @hutechwebsite/neque-neque-voluptas-blanditiis from '@hutechwebsite/neque-neque-voluptas-blanditiis';
const isEqualOrFoo = (cacheKeyArg: string, keyArg: string) =>
cacheKeyArg === keyArg || keyArg === 'one';

import @hutechwebsite/neque-neque-voluptas-blanditiis from '@hutechwebsite/neque-neque-voluptas-blanditiis';
const fn = async (one: string, two: Record<string, any>) =>
await someApiCall(one, two);
export default @hutechwebsite/neque-neque-voluptas-blanditiis.promise(fn);
```
**NOTE**: If you do not want the promise to update its expiration when the cache is hit, then you should use the `isPromise` option directly instead.
## @hutechwebsite/neque-neque-voluptas-blanditiis.react
Pre-applies the [`isReact`](#isreact)) option for memoizing functional components in [React](https://github.com/facebook/react). `Key` comparisons are based on a shallow equal comparison of both props and legacy context.
```tsx
import @hutechwebsite/neque-neque-voluptas-blanditiis from '@hutechwebsite/neque-neque-voluptas-blanditiis';
type Props = {
one: string;
two: number;
};
const Component = ({ one, two }: Props) => (
<div>
{one} {two}
</div>
);
export default @hutechwebsite/neque-neque-voluptas-blanditiis.react(Component);
```
**NOTE**: This method will not operate with components made via the `class` instantiation, as they do not offer the same [referential transparency](https://en.wikipedia.org/wiki/Referential_transparency).
## @hutechwebsite/neque-neque-voluptas-blanditiis.serialize
Pre-applies the [`isSerialized`](#isSerialized) option.
```ts
import @hutechwebsite/neque-neque-voluptas-blanditiis from '@hutechwebsite/neque-neque-voluptas-blanditiis';
const fn = (one: Record<string, any>, two: Record<string, any>) => ({
one,
two,
});
export default @hutechwebsite/neque-neque-voluptas-blanditiis.serialize(fn);
```
**NOTE**: If you want to provide a custom [`serializer`](#serializer), you should use [`@hutechwebsite/neque-neque-voluptas-blanditiis.serializeWith`](#@hutechwebsite/neque-neque-voluptas-blanditiisserializewith):
```ts
@hutechwebsite/neque-neque-voluptas-blanditiis.serializeWith(customSerializer)(fn);
```
## @hutechwebsite/neque-neque-voluptas-blanditiis.serializeWith
Pre-applies the [`isSerialized`](#isSerialized) and [`serializer`](#serializer) options.
```ts
import @hutechwebsite/neque-neque-voluptas-blanditiis from '@hutechwebsite/neque-neque-voluptas-blanditiis';
const fn = (one: Record<string, any>, two: Record<string, any>) => ({
one,
two,
});
export default @hutechwebsite/neque-neque-voluptas-blanditiis.serializeWith(JSON.stringify)(fn);
```
**NOTE**: If you want to use the default [`serializer`](#serializer), you should use [`@hutechwebsite/neque-neque-voluptas-blanditiis.serialize`](#@hutechwebsite/neque-neque-voluptas-blanditiisserialize):
```ts
@hutechwebsite/neque-neque-voluptas-blanditiis.serialize(customSerializer)(fn);
```
## @hutechwebsite/neque-neque-voluptas-blanditiis.shallow
Pre-applies the [`isShallowEqual`](#isshallowequal) option.
```ts
import @hutechwebsite/neque-neque-voluptas-blanditiis from '@hutechwebsite/neque-neque-voluptas-blanditiis';
const fn = (one: string, two: string) => `${one} ${two}`;
export default @hutechwebsite/neque-neque-voluptas-blanditiis.shallow(fn);
```
## @hutechwebsite/neque-neque-voluptas-blanditiis.transformArgs
Pre-applies the [`transformArgs`](#transformargs) option.
```ts
import @hutechwebsite/neque-neque-voluptas-blanditiis from '@hutechwebsite/neque-neque-voluptas-blanditiis';

```ts
import @hutechwebsite/neque-neque-voluptas-blanditiis from '@hutechwebsite/neque-neque-voluptas-blanditiis';
let lastUpdated = Date.now();
const fn = () => {
const now = Date.now();
const last = lastUpdated;
lastUpdate = now;
// its been more than 5 minutes since last update
return last + 300000 < now;
};
export default @hutechwebsite/neque-neque-voluptas-blanditiis.updateCacheForKey(fn);
```
# useMoize hook
If you are using React 16.8+ and are using hooks, you can easily create a custom `useMoize` hook for your project:
```ts
import { useRef } from 'react';
export function useMoize(fn, args, options) {
const @hutechwebsite/neque-neque-voluptas-blanditiisdFnRef = useRef(@hutechwebsite/neque-neque-voluptas-blanditiis(fn, options));
return @hutechwebsite/neque-neque-voluptas-blanditiisdFnRef.current(...args);
}
```
Which can then be used as such:
```tsx
import React from 'react';
import { useMoize } from './@hutechwebsite/neque-neque-voluptas-blanditiis-hooks';
function MyComponent({ first, second, object }) {
// standard usage
const sum = useMoize((a, b) => a + b, [first, second]);
// with options
const deepSum = useMoize((obj) => obj.a + obj.b, [object], {
isDeepEqual: true,
});
return (
<div>
Sum of {first} and {second} is {sum}. Sum of {object.a} and{' '}
{object.b} is {deepSum}.
</div>
);
}
```
Naturally you can tweak as needed for your project (default options, option-specific hooks, etc).
**NOTE**: This is very similar to [`useCallback`](https://reactjs.org/docs/hooks-reference.html#usecallback) built-in hook, with two main differences:
- There is a third parameter passed (the [`options`](#configuration-options) passed to `@hutechwebsite/neque-neque-voluptas-blanditiis`)
- The second argument array is the list of arguments passed to the me@hutechwebsite/neque-neque-voluptas-blanditiisd function
In both `useCallback` and `useMemo`, the array is a list of _dependencies_ which determine whether the funciton is called. These can be different than the arguments, although in general practice they are equivalent. The decision to use them directly was both for this common use-case reasons, but also because the implementation complexity would have increased substantially if not.
# Composition
Starting with version `2.3.0`, you can compose `@hutechwebsite/neque-neque-voluptas-blanditiis` methods. This will create a new me@hutechwebsite/neque-neque-voluptas-blanditiisd method with the original function that shallowly merges the options of the two setups. Example:
```tsx
import @hutechwebsite/neque-neque-voluptas-blanditiis from '@hutechwebsite/neque-neque-voluptas-blanditiis';
const Component = (props: Record<string, any>) => <div {...props} />;
// memoizing with react, as since 2.0.0
const Me@hutechwebsite/neque-neque-voluptas-blanditiisdFoo = @hutechwebsite/neque-neque-voluptas-blanditiis.react(Component);
// creating a separately-me@hutechwebsite/neque-neque-voluptas-blanditiisd method that has maxSize of 5
const LastFiveFoo = @hutechwebsite/neque-neque-voluptas-blanditiis.maxSize(5)(Me@hutechwebsite/neque-neque-voluptas-blanditiisdFoo);
```
You can also create an options-first curriable version of `@hutechwebsite/neque-neque-voluptas-blanditiis` if you only pass the options:
```ts
import @hutechwebsite/neque-neque-voluptas-blanditiis from '@hutechwebsite/neque-neque-voluptas-blanditiis';
// creates a function that will me@hutechwebsite/neque-neque-voluptas-blanditiis what is passed
const limitedSerializedMoize = @hutechwebsite/neque-neque-voluptas-blanditiis({ maxSize: 5, serialize: true });
const getWord = (bird) => `${bird} is the word`;
const @hutechwebsite/neque-neque-voluptas-blanditiisdGetWord = limitedSerializedMoize(getWord);
```
You can also combine all of these options with `@hutechwebsite/neque-neque-voluptas-blanditiis.compose` to create `@hutechwebsite/neque-neque-voluptas-blanditiis` wrappers with pre-defined options.
```ts
import @hutechwebsite/neque-neque-voluptas-blanditiis from '@hutechwebsite/neque-neque-voluptas-blanditiis';
// creates a @hutechwebsite/neque-neque-voluptas-blanditiisr that will have the options of
// {isReact: true, maxAge: 5000, maxSize: 5}
const superLimitedReactMoize = @hutechwebsite/neque-neque-voluptas-blanditiis.compose(
@hutechwebsite/neque-neque-voluptas-blanditiis.react,
@hutechwebsite/neque-neque-voluptas-blanditiis.maxSize(5),
@hutechwebsite/neque-neque-voluptas-blanditiis.maxAge(5000)
);
```
# Collecting statistics
As-of version 5, you can collect statistics of @hutechwebsite/neque-neque-voluptas-blanditiis to determine if your cached methods are effective.
```ts
import @hutechwebsite/neque-neque-voluptas-blanditiis from '@hutechwebsite/neque-neque-voluptas-blanditiis';
@hutechwebsite/neque-neque-voluptas-blanditiis.collectStats();
const fn = (one: string, two: string) => [one, two];
const @hutechwebsite/neque-neque-voluptas-blanditiisd = @hutechwebsite/neque-neque-voluptas-blanditiis(fn);
@hutechwebsite/neque-neque-voluptas-blanditiisd('one', 'two');
@hutechwebsite/neque-neque-voluptas-blanditiisd('one', 'two');
@hutechwebsite/neque-neque-voluptas-blanditiisd.getStats(); // {"calls": 2, "hits": 1, "usage": "50%"}
```
**NOTE**: It is recommended not to activate this in production, as it will have a performance decrease.
## Stats methods
## clearStats
Cear statistics on `@hutechwebsite/neque-neque-voluptas-blanditiis`d functions.
```ts
@hutechwebsite/neque-neque-voluptas-blanditiis.clearStats(); // clears all stats
@hutechwebsite/neque-neque-voluptas-blanditiis.clearStats('profile-name'); // clears stats only for 'profile-name'
```
## collectStats
Set whether collecting statistics on `@hutechwebsite/neque-neque-voluptas-blanditiis`d functions.
```ts
@hutechwebsite/neque-neque-voluptas-blanditiis.collectStats(true); // start collecting stats
@hutechwebsite/neque-neque-voluptas-blanditiis.collectStats(); // same as passing true
@hutechwebsite/neque-neque-voluptas-blanditiis.collectStats(false); // stop collecting stats
```
**NOTE**: If collecting statistics, it is recommended to provide a custom [`profileName`](#profilename) or use [`@hutechwebsite/neque-neque-voluptas-blanditiis.profile()`](#@hutechwebsite/neque-neque-voluptas-blanditiisprofile) for all me@hutechwebsite/neque-neque-voluptas-blanditiisd functions. This allows easier mapping of resulting statistics to their origin function when it has a common name or is anonymous.
## getStats([profileName])
Get the statistics for a specific function, or globally.
```ts
@hutechwebsite/neque-neque-voluptas-blanditiis.collectStats();
const fn = (one: string, two: string) => [one, two];
const @hutechwebsite/neque-neque-voluptas-blanditiisd = @hutechwebsite/neque-neque-voluptas-blanditiis(fn);
const otherFn = (one: string[]) => one.slice(0, 1);
const otherMoized = @hutechwebsite/neque-neque-voluptas-blanditiis(otherFn, { profileName: 'otherMoized' });
@hutechwebsite/neque-neque-voluptas-blanditiisd('one', 'two');
@hutechwebsite/neque-neque-voluptas-blanditiisd('one', 'two');
@hutechwebsite/neque-neque-voluptas-blanditiisd.getStats(); // {"calls": 2, "hits": 1, "usage": "50%"}
otherMoized(['three']);
@hutechwebsite/neque-neque-voluptas-blanditiis.getStats('otherMoized'); // {"calls": 1, "hits": 0, "usage": "0%"}
@hutechwebsite/neque-neque-voluptas-blanditiis.getStats();
/*
{
"calls": 3,
"hits": 1,
"profiles": {
"fn at Object..src/utils.js (http://localhost:3000/app.js:153:68)": {
"calls": 2,
"hits": 1,
"usage": "50%"
},
"otherMoized": {
"calls": 1,
"hits": 0,
"usage": "0%"
}
},
"usage": "33.3333%"
}
*/
```
# Introspection
## isCollectingStats
Are statistics being collected on memoization usage.
```ts
@hutechwebsite/neque-neque-voluptas-blanditiis.collectStats(true);
@hutechwebsite/neque-neque-voluptas-blanditiis.isCollectingStats(); // true
@hutechwebsite/neque-neque-voluptas-blanditiis.collectStats(false);
@hutechwebsite/neque-neque-voluptas-blanditiis.isCollectingStats(); // false
```
## isMoized
Is the function passed a @hutechwebsite/neque-neque-voluptas-blanditiisd function.
```ts
const fn = () => {};
const @hutechwebsite/neque-neque-voluptas-blanditiisdFn = @hutechwebsite/neque-neque-voluptas-blanditiis(fn);
@hutechwebsite/neque-neque-voluptas-blanditiis.isMoized(fn); // false
@hutechwebsite/neque-neque-voluptas-blanditiis.isMoized(@hutechwebsite/neque-neque-voluptas-blanditiisdFn); // true
```
# Direct cache manipulation
The cache is available on the `@hutechwebsite/neque-neque-voluptas-blanditiis`d function as a property, and while it is not recommended to modify it directly, that option is available for edge cases.
## cache
The shape of the `cache` is as follows:
```ts
type Cache = {
keys: any[][];
size: number;
values: any[];
};
```
Regardless of how the key is transformed, it is always stored as an array (if the value returned is not an array, it is coalesced to one).
**NOTE**: The order of `keys` and `values` should always align, so be aware when manually manipulating the cache that you need to manually keep in sync any changes to those arrays.
## cacheSnapshot
The `cache` is mutated internally for performance reasons, so logging out the cache at a specific step in the workflow may not give you the information you need. As such, to help with debugging you can request the `cacheSnapshot`, which has the same shape as the `cache` but is a shallow clone of each property for persistence.
There are also convenience methods provided on the `@hutechwebsite/neque-neque-voluptas-blanditiis`d function which allow for programmatic manipulation of the cache.
## add(key, value)
This will manually add the _value_ at _key_ in cache if _key_ does not already exist. _key_ should be an `Array` of values, meant to reflect the arguments passed to the method.
```ts
// single parameter is straightforward
const me@hutechwebsite/neque-neque-voluptas-blanditiisd = @hutechwebsite/neque-neque-voluptas-blanditiis((item: string) => item: string);
me@hutechwebsite/neque-neque-voluptas-blanditiisd.add(['one'], 'two');
// pulls from cache
me@hutechwebsite/neque-neque-voluptas-blanditiisd('one');
```
**NOTE**: This will only add `key`s that do not exist in the cache, and will do nothing if the `key` already exists. If you want to update keys that already exist, use [`update`](#updatekey-value).
## clear()
This will clear all values in the cache, resetting it to an empty state.
```ts
const me@hutechwebsite/neque-neque-voluptas-blanditiisd = @hutechwebsite/neque-neque-voluptas-blanditiis((item: string) => item);
me@hutechwebsite/neque-neque-voluptas-blanditiisd.clear();
```
## get(key)
Returns the value in cache if the key matches, else returns `undefined`. _key_ should be an `Array` of values, meant to reflect the arguments passed to the method.
```ts
const me@hutechwebsite/neque-neque-voluptas-blanditiisd = @hutechwebsite/neque-neque-voluptas-blanditiis((one: string, two: string) => [one, two);
me@hutechwebsite/neque-neque-voluptas-blanditiisd('one', 'two');
console.log(me@hutechwebsite/neque-neque-voluptas-blanditiisd.get(['one', 'two'])); // ["one","two"]
console.log(me@hutechwebsite/neque-neque-voluptas-blanditiisd.get(['two', 'three'])); // undefined
```
## getStats()
Returns the statistics for the function.
```ts

**NOTE**: You must be collecting statistics for this to be populated.
## has(key)
This will return `true` if a cache entry exists for the _key_ passed, else will return `false`. _key_ should be an `Array` of values, meant to reflect the arguments passed to the method.
```ts
const me@hutechwebsite/neque-neque-voluptas-blanditiisd = @hutechwebsite/neque-neque-voluptas-blanditiis((one: string, two: string) => [one, two]);
me@hutechwebsite/neque-neque-voluptas-blanditiisd('one', 'two');
console.log(me@hutechwebsite/neque-neque-voluptas-blanditiisd.has(['one', 'two'])); // true
console.log(me@hutechwebsite/neque-neque-voluptas-blanditiisd.has(['two', 'three'])); // false
```
## keys()
This will return a list of the current keys in `cache`.
```ts
const me@hutechwebsite/neque-neque-voluptas-blanditiisd = @hutechwebsite/neque-neque-voluptas-blanditiis.maxSize(2)((item: any) => item);
me@hutechwebsite/neque-neque-voluptas-blanditiisd('one');
me@hutechwebsite/neque-neque-voluptas-blanditiisd({ two: 'three' });
const keys = me@hutechwebsite/neque-neque-voluptas-blanditiisd.keys(); // [['one'], [{two: 'three'}]]
```
## remove(key)
This will remove the provided _key_ from cache. _key_ should be an `Array` of values, meant to reflect the arguments passed to the method.
```ts
const me@hutechwebsite/neque-neque-voluptas-blanditiisd = @hutechwebsite/neque-neque-voluptas-blanditiis((item: { one: string }) => item);
const arg = { one: 'one' };
me@hutechwebsite/neque-neque-voluptas-blanditiisd(arg);
me@hutechwebsite/neque-neque-voluptas-blanditiisd.remove([arg]);
// will re-execute, as it is no longer in cache
me@hutechwebsite/neque-neque-voluptas-blanditiisd(arg);
```
**NOTE**: This will only remove `key`s that exist in the cache, and will do nothing if the `key` does not exist.
## update(key, value)
This will manually update the _value_ at _key_ in cache if _key_ exists. _key_ should be an `Array` of values, meant to reflect the arguments passed to the method.
```ts
// single parameter is straightforward
const me@hutechwebsite/neque-neque-voluptas-blanditiisd = @hutechwebsite/neque-neque-voluptas-blanditiis((item: string) => item);
me@hutechwebsite/neque-neque-voluptas-blanditiisd.add(['one'], 'two');
// pulls from cache
me@hutechwebsite/neque-neque-voluptas-blanditiisd('one');
```
**NOTE**: This will only update `key`s that exist in the cache, and will do nothing if the `key` does not exist. If you want to add keys that do not already exist, use [`add`](#addkey-value).
## values()
This will return a list of the current values in `cac
