svelte-cachedb

A JSON database leveraging Svelte's writable stores and local storage

Getting Started

1. Install svelte-cachedb: yarn add -D svelte-cachedb

2. Add context provider to Svelte

   <!-- src/index.svelte -->
   <script>
     import CacheDB from 'svelte-cachedb'
     import App from './App.svelte'
   </script> 
    
   <CacheDB>
     <App />
   </CacheDB>

3. Access with getContext('cachedb')

   <script>
     import { getContext } from 'svelte'
     const { db } = getContext('cachedb')
    
     // updates to db store will automatically write out to localStorage
     db.update((d) => ({ ...d, newProp: 'newValue' }))
   </script>
