Simple in-memory caching for Node.js apps.
Create a new instance of the cache, passing in the TTL for its items in seconds:
const cache = new Cache(900)The following methods are exposed:
set(key: string, value: T): void get(key: string): T | null delete(key: string): void // Clears all items from the cache clear(): voidimport { Cache } from '@savla-dev/node-cache' const cache = new Cache<unknown>(900) // 15 minutes TTL async function fetchWithCache(url: string): Promise<any> { const cachedData = cache.get(url) if (cachedData) { console.log('Returning cached data') return cachedData } console.log('Fetching new data') let response: Response try { response = await fetch(url) } catch (e) { throw new Error(`Error during fetch: ${e}`) } try { const data = await response.json() cache.set(url, data) return data } catch (e) { console.log(`Error during response parsing: ${e}`) } }
