📃 Flexible, Atomic Global State Management for Svelte 5 Rune

Basic Usage

Define your stores:

import { ion } from 'ionia';

export const counter = ion(0);

Use them in your components:

<script lang="ts">
     import { counter } from '$stores';
</script>

<p>{counter.$}</p>
<button onclick={() => counter.$++}>Increment Counter</button>

Further Examples

// stores.ts
import { ion, ionReadOnly, ionWithReset, ionWithStorage } from 'ionia';

// Primary Store
export const counter = ion(0);

// Derived Globaly Store
export const counterPlusOne = ion<number>((get) => get(counter) + 1);

// Read Only Store
export const readOnlyCounter = ionReadOnly(counter);

// or Alternatively
export const counterPlusOne = ion<number>((get) => get(counter));

// Resettable
export const counter = ionWithReset(0);

// Local Storage
export const storageCounter = ionWithStorage('counter', 0);

Usage in svelte files:

<script lang="ts">
     import { counter, counterPlusOne } from '$stores';
</script>

<p>{counter.$}</p>
<button onclick={() => counter.$++}>Increment Counter</button>

or a Derived Example

<script lang="ts">
     import { counterPlusOne, counter } from '$stores';
</script>

<p>{counterPlusOne.$}</p>
<button onclick={() => counter.$++}>Increment Counter</button>
