### Install memoza

Source: https://github.com/letstri/memoza/blob/main/README.md

Install the memoza package using npm.

```sh
npm install memoza
```

### Custom Cache Key Derivation

Source: https://github.com/letstri/memoza/blob/main/README.md

Provide a custom `cacheKey` function to control how cache keys are generated based on arguments. This example uses a string template combining arguments.

```ts
const fn = memoize((a: number, b: number) => a + b, {
  cacheKey: (a, b) => `${a}-${b > 2}`,
})

fn(1, 2) // stored
fn(1, 5) // stored
fn(1, 7) // from cache (same key as above)
```

--------------------------------

### Basic Usage of memoize

Source: https://github.com/letstri/memoza/blob/main/README.md

Import and use the `memoize` function for basic memoization. The first call computes the result, while subsequent calls with the same arguments retrieve it from the cache.

```ts
import { memoize } from 'memoza'

const add = memoize((a: number, b: number) => a + b)

add(1, 2) // computed
add(1, 2) // from cache
```

--------------------------------

### Cache Utility Functions

Source: https://github.com/letstri/memoza/blob/main/README.md

Import and use utility functions like `isMemoized`, `getCacheStore`, and `clearMemoizeCache` to inspect and manage memoized functions and their caches.

```ts
import { clearMemoizeCache, getCacheStore, isMemoized } from 'memoza'

isMemoized(fn) // true if fn was created with memoize()
getCacheStore(fn) // returns { cache, fallbackEntries } or null
clearMemoizeCache(fn) // clears all cached entries
```

--------------------------------

### Promise Support and Automatic Eviction

Source: https://github.com/letstri/memoza/blob/main/README.md

memoza supports promises. Failed promises are automatically removed from the cache, allowing subsequent calls to retry the operation.

```ts
const fn = memoize(async (id: string) => fetchData(id))

await fn('a') // computed
await fn('a') // from cache
// if the promise rejects, the entry is removed and the next call re-runs
```

--------------------------------

### Cache Expiration with maxAge

Source: https://github.com/letstri/memoza/blob/main/README.md

Configure a memoized function to expire cached entries after a specified time in milliseconds using the `maxAge` option.

```ts
const fn = memoize(fetchUser, { maxAge: 5000 })
```
