Plugin details

Store data locally on the device using fast MMKV storage — with optional secure encryption for sensitive data.

Ideal for persisting user sessions, app preferences, onboarding flags, and more — even while offline.

📦 MMKV Storage = Native, Fast, Offline
🔐 Stored directly on the device using native C++-backed MMKV engine

🚀 Instant read/write performance (millisecond-level access)

📴 No internet required

📍 Storage is persistent across app restarts

🧱 Works like localStorage, but native and encrypted-ready


🔁 Example Use Case: Remember Dark Mode Setting
On app load, run a Load action with key dark_mode

Use the loaded_value state to set your app theme

When the user toggles the switch, run a Save with the new value

Bonus: Store values like onboarded=true, auth_token=xyz, etc.

Instructions

This plugin lets you securely store key-value data on the device using MMKV, one of the fastest and most reliable native storage engines for React Native.
It supports Save, Load, Delete, and Clear actions — and all operations happen instantly, offline, and namespaced per element.

✅ Step-by-Step Setup

1️⃣ Add the Plugin Element to Your Page
Drag the React Native Local Storage element onto your page.

This is a non-visual component, so it won’t be visible in the app.

2️⃣ (Optional) Set a Namespace
You can scope your storage by providing a custom namespace:

Prop: namespace (Text)

Example:
user_cache
session_data

If left blank, the plugin will generate a unique fallback ID automatically.

This namespace controls where data is stored in MMKV — useful if you want to isolate storage by feature or user.

You can place it anywhere (even outside the visible screen)
