# @push.rocks/smartcache
Cache things in smart ways.
## Install
To use `@push.rocks/smartcache` in your project, you'll need to install it using npm or yarn. Here's how you can do it:
```bash
npm install @push.rocks/smartcache --save
```
or if you are using yarn:
```bash
yarn add @push.rocks/smartcache
```
## Usage
`@push.rocks/smartcache` is designed to cache the results of function calls in a smart and efficient way, significantly improving the performance of repeat function calls by avoiding unnecessary recalculations or remote fetches. This package is especially useful when dealing with data that changes infrequently or expensive computation functions whose results can be reused within a given period. Here's how to use `@push.rocks/smartcache` in your TypeScript projects:
First, make sure to import `SmartCache`:
```typescript
import { SmartCache } from '@push.rocks/smartcache';
```
### Basic Example
Create an instance of `SmartCache`:
```typescript
const mySmartCache = new SmartCache();
```
Now, imagine you have an asynchronous function whose result you want to cache:
```typescript
async function fetchData(): Promise<string> {
// simulate fetching data
await new Promise(resolve => setTimeout(resolve, 1000)); // delay to mimic fetch time
return 'Some fetched data';
}
```
Using `@push.rocks/smartcache`, you can cache the result of `fetchData` easily:
```typescript
async function getCachedData() {
const cachedData = await mySmartCache.cacheReturn(fetchData, 60000); // Cache for 1 minute
console.log(cachedData); // 'Some fetched data'
}
```
### Advanced Use Cases
#### Custom Cache Identifiers
By default, `@push.rocks/smartcache` identifies cache entries based on the call stack. However, when you have dynamic arguments that significantly change the output of the function, you might want to create a custom cache identifier to differentiate between these calls.
Suppose `fetchData` now takes an argument:
```typescript
async function fetchData(userId: string): Promise<UserData> {
// Fetch user data based on userId
}
```
You could create a custom cache identifier like so:
```typescript
const userId = '123';
const customIdentifier = `fetchData-${userId}`;
const cachedUserData = await mySmartCache.cacheReturn(() => fetchData(userId), 60000, customIdentifier);
```
#### Clearing the Cache
In certain situations, you might want to clear the cached data before it expires naturally. `@push.rocks/smartcache` provides a method to manually clear specific cache entries:
```typescript
mySmartCache.clearCache(customIdentifier);
```
### Best Practices
- **Cache Duration**: Choose a cache duration that makes sense for your data. Highly dynamic data might not benefit much from long cache times, whereas static data can be cached longer.
- **Error Handling**: Always implement error handling for your cached functions, especially when dealing with network requests.
- **Memory Management**: Be mindful of what you cache. Caching large objects or a high number of entries can lead to increased memory usage.
### Conclusion
`@push.rocks/smartcache` is a powerful utility for caching asynchronous function results, significantly improving the performance and efficiency of your applications. By understanding and implementing the basics and exploring advanced use cases, you can leverage `@push.rocks/smartcache` to its full potential.
Remember, the key to effective caching is understanding your data's behavior and aligning your caching strategy accordingly. Happy caching!
