# Micache ⚡
> Simple cache & caching fetched data strategy
[](https://badge.fury.io/js/micache)
🪶 Just lightweight
## `createCache`
### Simple cache
```js
import { createCache } from "micache";
const myCache = createCache();
myCache.set("123", { name: "Denji" });
myCache.get("123"); // { name: "Denji" }
```
### Cache with expiring keys
```js
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`
```js
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.
