-As the library will swallow errors encountered when writing to the browser storage, or parsing the string value gotten from browser storage, it is possible to specify a custom function to handle the error. Should the swallowing not be desirable, it is possible to re-throw the error like the following example (not recommended):
-
-```javascript
-export const preferences = persisted('local-storage-key', 'default-value', {
-  onWriteError: (e) => {
-    throw e
-  },
-  onParseError: (newVal, e) => {
-    throw e
-  }
-})
-```
-
-The newVal parameter passed to the onParseError handler is the string value which was attempted (but failed) to serialize
