fluidstate-mobx

fluidstate-mobx is the MobX-based reactive layer for fluidstate. It bridges the declarative, ergonomic API of fluidstate with the powerful and battle-tested reactive engine of MobX.

Key Features

• Seamless Integration: Implements the fluidstate's ReactiveLayer, providing atoms, computed values, and reactions powered by MobX's core APIs (createAtom, computed, autorun).

• State Isolation: Automatically configures MobX with isolateGlobalState: true to ensure it can coexist with other MobX instances in the same application without conflicts.

• Enables fluidstate: Once configured, you can use the complete feature set of fluidstate for your state management needs.

• Convenient MobX Access: Re-exports all MobX APIs, allowing you to use them directly without adding mobx as a separate dependency.

Installation

To use fluidstate with MobX, you need to install fluidstate and fluidstate-mobx:

npm install fluidstate fluidstate-mobx

or

yarn add fluidstate fluidstate-mobx

Usage

To enable fluidstate, you must provide it with the MobX reactive layer. This is a one-time setup at your application's entry point.

import {
  provideReactiveLayer,
  createReactive,
  createReaction,
  runAction,
} from "fluidstate";
import { getReactiveLayer } from "fluidstate-mobx";

// 1. Get the reactive layer from fluidstate-mobx
const reactiveLayer = getReactiveLayer();

// 2. Provide it to fluidstate
provideReactiveLayer(reactiveLayer);

// 3. You can now use the fluidstate API throughout your application
const counter = createReactive({ value: 0 });

createReaction(() => {
  console.log(`Counter value: ${counter.value}`);
});
// LOGS: Counter value: 0

runAction(() => {
  counter.value++;
});
// LOGS: Counter value: 1
 

After this setup, you can use the fluidstate package for all your state management tasks. For more details on createReactive, createReaction, and other features, please refer to the main fluidstate documentation.

Using MobX APIs

While fluidstate provides a high-level abstraction, you may occasionally need to use MobX APIs directly. For convenience, fluidstate-mobx re-exports the entire MobX library from a separate entry point.

This ensures you are using the same instance of MobX that powers fluidstate, which can help prevent version conflicts or bundling issues.

// Instead of a direct import: import { observable } from "mobx";
import { observable } from "fluidstate-mobx/mobx";
 

This is an optional convenience and is not required for standard fluidstate usage.
