## Install
This project uses [node](http://nodejs.org) and [npm](https://npmjs.com). Go check them out if you don't have them locally installed.
```sh
npm install --save unissist
```
Then with a module bundler like [webpack](https://webpack.js.org) or [rollup](http://rollupjs.org), use as you would anything else:
```js
// The helper:
import persistStore from 'unissist';
// localStorage Adapter
import localStorageAdapter from 'unissist/integrations/localStorageAdapter';
// indexedDB Adapter
import indexedDBAdapter from 'unissist/integrations/indexdbAdapter';
// AsyncStorage Adapter
import asyncStorageAdapter from 'unissist/integrations/asyncStorageAdapter';
```
The [UMD](https://github.com/umdjs/umd) build is also available on [unpkg](https://unpkg.com):
```html
```
You can find the library on `window.unissist`.
### Usage
```js
// use unistore like you always would, but use the unissist helper to persist state
import createStore from 'unistore'
import persistStore from 'unissist'
import localStorageAdapter from 'unissist/integrations/localStorageAdapter';
const store = createStore({ count: 0 })
const adapter = localStorageAdapter();
persistStore(store, adapter);
// store state now includes a `hydrated` that tells you whether or not the state has been rehydrated from the store
```
Unissist also takes a third parameter that allows you to configure how your peristence works
```js
import createStore from 'unistore'
import persistStore from 'unissist'
import localStorageAdapter from 'unissist/integrations/localStorageAdapter';
const store = createStore({ count: 0 })
const adapter = localStorageAdapter();
// Default values except migration
let config = {
version: 1,
debounceTime: 100,
// called when version is updated. Accepts promises. Defaults to dropping the store
migration: (oldState, oldversion) => ({ /* new state */ }),
// takes in the current state and returns the state to be persisted
map: state => ({ /* new persisted state shape */ })
// takes in state that will be hydrated and returns the new state shape
hydration: state => ({ /* new state shape */ })
}
persistStore(store, adapter, config);
```
