+Static cache middleware for koa.
 
 Differences between this library and other libraries such as [static](https://github.com/koajs/static):
 
 - There is no directory or `index.html` support.
 - You may optionally store the data in memory - it streams by default.
 - Caches the assets on initialization - you need to restart the process to update the assets.(can turn off with options.preload = false)
 - Uses MD5 hash sum as an ETag.
-- Uses .gz files if present on disk, like nginx gzip_static module
+- Uses `.gz` files if present on disk, like nginx gzip_static module
+
+> Forked from https://github.com/koajs/static-cache, refactor with TypeScript to support CommonJS and ESM both.
 
 ## Installation
 
-```js
-$ npm install koa-static-cache
+```bash
+npm install @eggjs/koa-static-cache

 - `options.dir` (str) - the directory you wish to serve, default to `process.cwd`.
 - `options.maxAge` (int) - cache control max age for the files, `0` by default.
 - `options.cacheControl` (str) - optional cache control header. Overrides `options.maxAge`.

 For example, if you want to change the max age of `/package.json`, you can do the following:
 
 ```js
-var files = {}
+const files = {};
 
 app.use(staticCache('/public', {
   maxAge: 60 * 60 * 24 * 365

 ```
 
 #### Using a LRU cache to avoid OOM when dynamic mode enabled
 
 You can pass in a lru cache instance which has tow methods: `get(key)` and `set(key, value)`.
 
 ```js
-var LRU = require('lru-cache')
-var files = new LRU({ max: 1000 })
+const LRU = require('lru-cache');

 app.use(staticCache({
   dir: '/public',
   dynamic: true,
-  files: files
-}))
+  files,
