+### Node Cache
+
+This example implementation uses [node-cache](https://github.com/node-cache/node-cache) as a storage method. Do note 
+that this library is somewhat old, however it appears to work at the time of writing.
+
+```ts
+import { buildStorage } from "axios-cache-interceptor";
+import NodeCache from "node-cache";
+
+const cache = new NodeCache({ stdTTL: 60 * 60 * 24 * 7 });
+
+const cacheStorage = buildStorage({
+  find(key) {
+    return cache.get(key)
+  }
+
+  set(key, value) {
+    cache.set(key, value);
+  },
+
+  remove(key) {
+    cache.del(key);
+  },
+});
+
+```
