Getting started
The React-mobx-manager package is distributed using npm, the node package manager.
npm i --save @lomray/react-mobx-manager @lomray/consistent-suspense
NOTE: this package use @lomray/consistent-suspense for generate stable id's inside Suspense.
Choose one of store id generating strategy (1 or 2 or 3):
- Configure your bundler to keep classnames and function names. Store id will be generated from class names (chose unique class names).
- React: (craco or webpack config, terser options)
terserOptions.keep_classnames = true;
terserOptions.keep_fnames = true;
- React Native: (metro bundler config: metro.config.js)
module.exports = {
transformer: {
minifierConfig: {
keep_classnames: true,
keep_fnames: true,
},
}
}
- Define
id
for each store.
import { makeObservable } from "mobx";
class MyStore {
/**
* Define unique store id
*/
static id = 'Unique-store-id';
constructor() {
makeObservable(this, {})
}
}
- Use
Vite plugins
.
import { defineConfig } from 'vite';
import react from '@vitejs/plugin-react';
import MobxManager from '@lomray/react-mobx-manager/plugins/vite/index';
// https://vitejs.dev/config/
export default defineConfig({
/**
* Store id's will be generated automatically, just chill
*/
plugins: [react(), MobxManager()]
});
/**
* Detect mobx store:
- by makeObservable or makeAutoObservable
- by @mobx-store jsdoc before class
*/
Usage
Import Manager, StoreManagerProvider
from @lomray/react-mobx-manager
into your index file and wrap <App/>
with <StoreManagerProvider/>
import React from 'react';
import ReactDOM from 'react-dom/client';
import { ConsistentSuspenseProvider } from '@lomray/consistent-suspense';
import { Manager, StoreManagerProvider, MobxLocalStorage } from '@lomray/react-mobx-manager';
import App from './app';
import MyApiClient from './services/my-api-client';
import './index.css';
const apiClient = new MyApiClient();
const storeManager = new Manager({
storage: new MobxLocalStorage(), // optional: needs for persisting stores
storesParams: { apiClient }, // optional: we can provide our api client for access from the each store
});
const root = ReactDOM.createRoot(document.getElementById('root') as HTMLElement);
root.render(
<React.StrictMode>
<ConsistentSuspenseProvider> {/** required **/}
<StoreManagerProvider storeManager={storeManager} shouldInit>
<App />
</StoreManagerProvider>
</ConsistentSuspenseProvider>
</React.StrictMode>,
);
Connect mobx store to the manager, and you're good to go!
import { withStores, Manager } from '@lomray/react-mobx-manager';
import { makeObservable, observable, action } from 'mobx';
import type { IConstructorParams, ClassReturnType } from '@lomray/react-mobx-manager';
/**
* Mobx user store
*
* Usually store like that are related to the global store,
* because they store information about the current user,
* which may be needed in different places of the application.
*
* You may also want to save the state of the store, for example,
* to local storage, so that it can be restored after page reload,
* in this case, just export wrap export with 'persist':
* export default Manager.persistStore(UserStore, 'user');
*/
class UserStore {
/**
* Required only if we don't configure our bundler to keep classnames and function names
* Default: current class name
*/
static id = 'user';
/**

// this.otherStore = getStore(SomeOtherStore);
makeObservable(this, {
name: observable,
setName: action.bound,
});
}
/**
* Set user name
*/
public setName(name: string): void {
this.name = name;
}
/**
* Example async
* Call this func from component
*/
public getNameFromApi = async (userId: number) => {
const name = await this.apiClient.fetchName(userId);
this.setName(name);
}
}
/**
* Define stores for component
*/
const stores = {
userStore: UserStore
};
// support typescript
type TProps = StoresType <typeof stores>;
/**
* User component
*/
const User: FC<TProps> = ({ userStore: { name } }) => {
return (
<div>{name}</div>
)
}
/**
* Connect stores to component
*/
export default withStores(User, stores);
See app example for a better understanding.
Support SSR
Does this library support SSR? Short answer - yes, but we need some steps to prepare our framework.
- Look at Vite demo app for a better understanding.
- Look at After.js (razzle) based project for a better understanding.
- Look at NextJS example for a better understanding (needs writing a wrapper).
Important Tips
- Create global store only for e.g: application settings, logged user, theme, etc.
- To get started, stick to the concept: Store for Component. Don't connect (through withStores) not global store to several components.
