Micache ⚡

Simple cache & caching fetched data strategy

🪶 Just lightweight

createCache

Simple cache

import { createCache } from "micache";

const myCache = createCache();

myCache.set("123", { name: "Denji" });
myCache.get("123"); // { name: "Denji" }

Cache with expiring keys

import { createCache } from "micache";

const myTemporaryCache = createCache({ expireSec: 30 });

myTemporaryCache.set("567", { name: "Power" });
myTemporaryCache.get("567"); // { name: "Power" }
// 30 seconds later ...
myTemporaryCache.get("567"); // undefined

createAsyncCache

import { createAsyncCache } from "micache";
import redaxios from "redaxios";

async function fetchPrice(fromCoinId, toCoinId){
  const response = await redaxios.get(
    "https://min-api.cryptocompare.com/data/pricemultifull",
    {
      params: {
        fsyms: fromCoinId,
        tsyms: toCoinId,
      },
    }
  );

  return response.data.RAW[fromCoinId][toCoinId].PRICE;
}

const getPrice = createAsyncCache(fetchPrice, { expireSec: 30 });

let price = await getPrice("BTC", "USD"); // 46201,98
price = await getPrice("BTC", "USD"); // very fast with cache => 46201,98
// 30 seconds later ...
price = await getPrice("BTC", "USD"); // 46337,73

createFsCache

Create cache using filesystem. Cache is stored in node_modules/.micache-fs folder.

createFileMapCache

Create a mapping between file content and data related to this content. This method is using createFsCache to store cache.
