### Persist Svelte Store with SessionStorage

Source: https://github.com/macfja/svelte-persistent-store/blob/main/README.md

Shows how to use `persistBrowserSession` to create a Svelte store that persists its value only for the current browser session (using SessionStorage). It includes an example of initializing the store and updating its value.

```javascript
import { persistBrowserSession } from "@macfja/svelte-persistent-store"
import { writable } from "svelte/store"

let title = persistBrowserSession(writable("Unsaved"), "document-name")

$title = "My Document"

// if you reload the page the value of $title is 'My Document'
```

--------------------------------

### Run Lint and Test Commands

Source: https://github.com/macfja/svelte-persistent-store/blob/main/CONTRIBUTING.md

This snippet shows the commands to run for checking code quality and tests within the svelte-persistent-store project. It ensures that the code adheres to project standards and that all tests pass.

```sh
npm run lint
npm run test
```

### Create Persistent Writable Store

Source: https://github.com/macfja/svelte-persistent-store/blob/main/README.md

Demonstrates creating a persistent writable store directly using the `writable` function from the library, which defaults to LocalStorage. It shows initialization and updating the store's value.

```javascript
import { writable } from "@macfja/svelte-persistent-store"

// Create a wriatble store, persisted in browser LocalStorage, with the key `name`
let name = writable("name", "John")

$name = "Jeanne Doe"

// if you reload the page the value of $name is 'Jeanne Doe'
```

--------------------------------

### Persist Svelte Store with LocalStorage

Source: https://github.com/macfja/svelte-persistent-store/blob/main/README.md

Demonstrates how to use the `persist` function with `createLocalStorage` to create a Svelte store that saves its value to the browser's LocalStorage. It shows how to initialize the store with a default value and how to update it.

```javascript
import { persist, createLocalStorage } from "@macfja/svelte-persistent-store"
import { writable } from "svelte/store"

let name = persist(writable("John"), createLocalStorage(), "name")

$name = "Jeanne Doe"

// if you reload the page the value of $name is 'Jeanne Doe'
```

### Persist Function Signature

Source: https://github.com/macfja/svelte-persistent-store/blob/main/README.md

Provides the TypeScript type signature for the `persist` function, detailing its parameters: a Svelte writable store, a storage interface implementation, and a key for persistence. It also mentions the addition of a `delete` function to the returned store.

```typescript
declare function persist<T>(store: Writable<T>, storage: StorageInterface<T>, key: string): PersistentStore<T>
```
