Simple memory cache function.
Some times you want to cache a value but don't need a complex caching system. This package helps you cache values in side the memory of your application.
yarn add @kaliber/cache
import fetch from 'node-fetch'
import { createCache } from '@kaliber/cache'
const cache = createCache({ allowReturnExpiredValue: false, expirationTime: 1000 })
function handleRequest(postId) {
const data = cache({
cacheKey: ['post', postId],
async getValue() {
const response = await fetch(`https://jsonplaceholder.typicode.com/posts/${postId}`)
return await response.json()
}
})
return data
}| Property | Value | Description |
|---|---|---|
| allowReturnExpiredValue | false | if false the expirationTime will be leading in getting results from the cache |
| allowReturnExpiredValue | true | if true the cache is in 'unsafe' safe mode this means that the cache will always return a value even if the cache time is expired. Of course the cache needs to have a value to get value from it. |
| expirationTime | number | (in milliseconds) this is the time the cache is valid. |
