# rev-hash

> Create a hash for file revving

It will create an `md5` hash from an input buffer or string, and truncate it to 10 characters, which is unique enough for this purpose.

If you think you need a different hash algorithm or a longer hash, [you're wrong](https://blog.risingstack.com/automatic-cache-busting-for-your-css/).

## Install

```sh
npm install rev-hash
```

```js
import fs from 'node:fs';
import revisionHash from 'rev-hash';
