How do I handle asynchronous actions in Unistore?

Unistore handles async actions by allowing you to define actions as async functions that return state updates or call store.setState() after async operations. For example, the README shows an async action that fetches data, but you need to manage stale state by using store.getState() for up-to-date values.

Unistore vs Redux: which is better for performance?

Unistore is better for performance when bundle size is the priority, as it's only 350 bytes core vs Redux's larger footprint. However, Redux might offer better tooling for complex apps, so choose based on trade-offs between size and features.

Does Unistore support TypeScript?

The README does not mention TypeScript support, so while you can use it with TypeScript, you'll likely need to add your own type definitions. This lack of built-in type safety could be a drawback for projects requiring strict typing.

How to set up Redux devtools with Unistore?

To use Redux devtools, import 'unistore/devtools' and conditionally create the store in development mode, as shown in the DEBUG section. This requires having the Redux devtools extension installed and adds extra configuration steps.

Can Unistore handle complex state management?

Unistore can handle basic to moderately complex state, but its simplicity means you might need more manual work for advanced logic like middleware or time-travel debugging. It's best suited for projects where minimalism outweighs feature richness.

What's the bundle size when using Unistore with Preact?

Using Unistore with Preact adds about 650 bytes to your bundle, as stated in the README, since the core is 350 bytes and integration adds around 300 bytes. This makes it a lightweight choice for Preact apps.

What is unistore?

Unistore is a tiny centralized state container for JavaScript applications, specifically designed to work with Preact and React. It provides a Redux-like API for managing application state with a minimal footprint, solving the problem of state management complexity in lightweight frontend projects.

Target Audience

Frontend developers using Preact or React who need a simple, performant state management solution without the overhead of larger libraries.

Value Proposition

Developers choose Unistore for its extremely small size (350b core), familiar Redux-like patterns, and seamless integration with Preact and React, making it ideal for performance-sensitive applications.

Overview

🌶 350b / 650b state container with component actions for Preact & React

Use Cases

Best For

Adding state management to Preact applications with minimal bundle impact
Migrating from Redux to a lighter alternative
Building performance-focused React apps where bundle size matters
Projects needing simple global state without complex middleware
Applications that benefit from portable, functional action definitions
Integrating state management that can run in web workers via Stockroom

Not Ideal For

Applications requiring complex asynchronous state management with middleware like Redux-Thunk
Teams that depend on Redux's extensive ecosystem of devtools and third-party plugins
Projects needing built-in TypeScript support for type-safe state management

Pros & Cons

Pros

Tiny Bundle Size

Core library is only 350 bytes, and with Preact integration it totals around 650 bytes, as stated in the README, making it ideal for performance-focused applications where bundle size is critical.

Redux-Like Familiarity

Uses names and patterns similar to Redux, such as actions and reducers, which eases adoption for developers already experienced with Redux, as highlighted in the README's key features.

Portable Action Functions

Actions can be defined as pure functions and imported anywhere, promoting code reusability and clean separation, as shown in the README examples where actions are shared across components.

Web Worker Support

Can seamlessly run in a web worker via Stockroom, enabling background state management for improved performance, a feature mentioned in the README as a new addition.

Cons

Manual Async Handling

Lacks built-in middleware for async actions; developers must manage asynchronous operations manually using async functions or direct store.setState() calls, as evidenced in the README where async actions require careful state updates.

Extra Debugging Setup

Integration with Redux devtools requires importing a separate module and environment checks, adding setup overhead compared to Redux's out-of-the-box support, as described in the DEBUG section of the README.

Limited Third-Party Tools

Due to its minimal nature, Unistore has a smaller ecosystem than Redux, meaning fewer plugins and community resources for advanced features, which could require custom solutions.

Open Source Alternative To

unistore is an open-source alternative to the following products:

Redux

A predictable state container for JavaScript applications, commonly used with libraries like React for managing application state in a consistent way.
