ew-responsive-store v0.0.3: The Ultimate Cross-Framework Storage Solution

Introduction

In the ever-evolving landscape of frontend development, managing persistent state across different frameworks has always been a challenge. Each framework has its own ecosystem, patterns, and best practices, making it difficult to share storage logic between projects or migrate between frameworks.

ew-responsive-store v0.0.3 emerges as a revolutionary solution that bridges this gap, providing a unified, framework-agnostic storage API that works seamlessly across Vue, React, Preact, Solid, Svelte, Angular, and even vanilla JavaScript.

What Makes ew-responsive-store Special?

🚀 Zero External Dependencies

Unlike many storage libraries that bundle framework dependencies, ew-responsive-store treats all framework dependencies as external. This means:

  • Smaller bundle sizes: Only the code you need is included
  • No version conflicts: Framework dependencies are managed by your project
  • Better tree-shaking: Unused code is automatically eliminated

🔄 Cross-Framework Consistency

All frameworks use the same useStorage API, making it incredibly easy to:

  • Share code between projects using different frameworks
  • Migrate between frameworks without rewriting storage logic
  • Maintain consistent patterns across your entire codebase

⚡ Real-time Cross-Tab Synchronization

Built-in support for cross-tab synchronization means your data stays consistent across all browser tabs automatically, without any additional setup.

🎯 Framework-Specific Optimizations

While maintaining API consistency, each framework gets optimizations tailored to its specific patterns:

  • Vue: Returns reactive refs with deep watching
  • React: Returns state tuples with proper re-rendering
  • Solid: Returns signals for fine-grained reactivity
  • Svelte: Returns stores for reactive updates
  • Angular: Returns signals for modern Angular patterns
  • Vanilla JS: Returns a storage manager with subscription support

// Subscribe to changes
storage.subscribe((newValue) => {
  console.log('Value changed:', newValue);
});
Enter fullscreen mode Exit fullscreen mode

Advanced Features

Cross-Tab Synchronization

All frameworks automatically sync data across browser tabs:

// In Tab 1
const [theme, setTheme] = useStorage('theme', 'light');
setTheme('dark');

// In Tab 2 - automatically updates to 'dark'
const [theme, setTheme] = useStorage('theme', 'light');
console.log(theme); // 'dark'
Enter fullscreen mode Exit fullscreen mode

Storage Type Selection

Choose between localStorage and sessionStorage:

import { useStorage, StoreType } from 'ew-responsive-store/react';

// localStorage (default)
const [persistentData, setPersistentData] = useStorage('data', {});

// sessionStorage
const [sessionData, setSessionData] = useStorage(
  'sessionData', 
  {}, 
  { storage: StoreType.SESSION }
);
Enter fullscreen mode Exit fullscreen mode

Complex Data Types

Handle objects, arrays, and complex data structures seamlessly:

const [user, setUser] = useStorage('user', {
  name: 'John',
  preferences: {
    theme: 'dark',
    notifications: true
  },
  todos: [
    { id: 1, text: 'Learn ew-responsive-store', completed: false }
  ]
});

// Update nested properties
setUser({
  ...user,
  preferences: {
    ...user.preferences,
    theme: 'light'
  }
});

This is really interesting and cool!

However, the framework migration is the only practical and specific scenario where It can be adopted.

The other ones you've listed are a bit vague. Do you have anything else in mind?

I'm working on decentralised applications and this is something I can see being adopted. There's GunJS DB that works by using distributed local storage and can be used directly.

There are also "federated" media and messaging servers like ActivityPub and Matrix and also blockchain and smart contract based system that all share the state. Perhaps you can come up with a unifying way of caching the state locally for performance and optimisations

Thank you for your feedback! You're absolutely right that framework migration is the most direct and practical use case. Regarding the decentralized application scenarios you mentioned, this is indeed a promising direction!

About Decentralized Storage Adaptation Possibilities:

The core strength of ew-responsive-store is providing a unified reactive storage interface, which could indeed be extended to decentralized scenarios:

  1. GunJS Integration - Could create an adapter that allows GunJS's distributed data to be accessed through the useStorage interface, enabling local caching + distributed synchronization

  2. ActivityPub/Matrix State Management - Federated protocol states could be cached locally and updated in real-time through reactive interfaces, improving user experience

  3. Blockchain State Caching - Smart contract states could be cached locally to reduce RPC calls while maintaining sync with on-chain state

Technical Implementation Concept:

// Conceptual design
const [userData, setUserData] = useDecentralizedStorage('user', {}, {
  adapter: 'gunjs', // or 'activitypub', 'matrix', 'blockchain'
  syncStrategy: 'realtime'
});
Enter fullscreen mode Exit fullscreen mode

However, you're right that these scenarios would require specific adapter implementations rather than simple configuration. If you have concrete decentralized application needs, I'd be happy to discuss how to design corresponding extensions for ew-responsive-store.

What type of decentralized applications are you currently working on? This would help me provide more targeted suggestions.

Thanks a lot for the thorough response. Unfortunately at the moment I'm not developing anything specific in that direction

I just got excited but this cool tool that you've build. In future I was looking into a possibility of building decentralised frontends, which has been rather neglected

It can be a server-side rendered or a slowly starting SPA that dynamically pulls the CSS and JS from somewhere: IFFS, WebRTC, you name it. Only condition that it's whitelisted and checked to prevent XSS

It doesn't necessary need to pull the whole page to render and can simply pull some blogs as through CMS but with executables. Another use-case is something conceptually similar to "Super App" concept like WeChat and Telegram

But never mind. Probably taking a couple of years before I could get into this. Thanks for the work!

Thank you for the detailed explanation! Your vision for decentralized frontends is really fascinating and ahead of its time. The concept of dynamically pulling CSS/JS from distributed sources like IPFS or WebRTC while maintaining security through whitelisting is exactly the kind of innovative thinking the web needs.

Regarding your ideas:

  1. Server-side rendered + dynamic asset loading - This could work beautifully with ew-responsive-store for state management across different asset sources

  2. CMS-like content with executables - The reactive storage could help manage dynamic content state and user interactions

  3. Super App concept - Having a unified storage layer across different "mini-apps" or modules would be incredibly valuable

Collaboration opportunity:
Since you're thinking about these concepts for the future, would you be interested in contributing to ew-responsive-store? Even if you're not actively developing decentralized apps right now, your perspective on future web architectures could be valuable for:

  • Designing APIs that work well with distributed systems
  • Planning features that support dynamic asset loading
  • Contributing to documentation or examples

The project is open source and welcomes contributors with different backgrounds and visions. Your input could help shape the library to be more future-ready for the decentralized web.
