Persist is an updated version of [webstorage-decorators](https://git.zakscode.com/ztimson/webstorage-decorators), a library which saves variables to local or session storage.
This library aims to improve upon the original's limitations by using the new [Proxy Object](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Proxy). Improvements include:
- Supports both objects & decorators
- Supports both OOP & Decorator patterns
- Proxy object ensures all changes are tracked including impure functions
- [Proto]types and functions can be preserved by passing the `type` option
JavaScript's decorators are currently undergoing changes to the API overseen by [TC39](https://tc39.es) and currently have no support for property decorators. [Experimental decorators](https://www.typescriptlang.org/tsconfig#experimentalDecorators) must be enabled to work properly.

Create a proxy object which wraps your data so any changes can be intercepted & synced with storage.
Your data is stored under the value property and should always be accessed/modified through it.
#### Example
```ts
class Theme {
// This property will automatically sync with localStorage
@Persist({default: 'os'}) current!: string;
constructor() {
console.log(this.current); // Output: os
this.current == localStorage.getItem('Thene.current'); // True
this.current = 'light';
console.log(this.current); // Output: light
}
}
```
#### Constructor
`persist(options?: {key?: string} & PersistOptions<T>)`
| Argument | Type | Description |
|-----------|--------------------------------------------------------------------|-------------------------------------------------------------------------------------------------------------------------------|
| `options` | `{key: string}` & [`PersistOptions<T>`](../Home.md#persistoptions) | Configure using [PersistOptions](../Home.md#persistoptions). Storage key can also be ovverriden by passing `key` as an option |
