I am just learning React JS. I want to get a value that is stored in mobx state in my application. But not getting any idea how to get mobx state in functional component.
const user_id = observer(({ GlobalStore }) =>
console.log(GlobalStore.user_id)
); // I just need the user ID.
This is the full code:
import { observer } from "mobx-react";
import Store from "../mobx/Store";
export const user_id = observer(({ GlobalStore }) =>
console.log(GlobalStore)
);
console.log(user_id);
And my Store.js file is as below:
import { observable, action, makeObservable, autorun } from "mobx"; class GlobalStore { site_title = "ABCD"; app_code = null; user_id = null; constructor() { makeObservable(this, { site_title: observable, app_code: observable, user_id: observable, update_title: action.bound, update_appcode: action.bound, update_userid: action.bound, }); } update_title(title) { this.site_title = title; } update_appcode(code) { this.app_code = code; } update_userid(id) { this.user_id = id; } } const Store = new GlobalStore(); autorun(() => { console.log("System Checking... OK") }) export default Store;
Because your store is a singleton you can just import it anywhere and access any field or method.
import { observer } from 'mobx-react';
import Store from './Store';
const SomeComponent = observer(() => {
return <div>user_id: {Store.user_id}</div>;
});
I've made example on Codesandbox
in Mobx Update Version We have autoObservable
import makeAutoObservable from Mobx and use it like i have used check out code sandbox
-> here You can Check
code for Your mobx Store
import { makeAutoObservable, runInAction } from 'mobx'; // import this
class GlobalStore {
user_id = 'id here';
constructor() {
makeAutoObservable(this); // call autuobservable inside constractor
}
update_userid(id) {
this.user_id = id;
}
}
const Store = new GlobalStore();
export default Store;
and here you can access your user id like this in app component or where else you want
import { observer } from 'mobx-react';
import React, { useEffect } from 'react';
import Store from './Store';
import './styles.css';
const App = observer(() => {
useEffect(() => {
setTimeout(() => {
Store.update_userid('new_id_111');
}, 3000);
}, []);
return (
<div className="App">
<h1>Hello CodeSandbox</h1>
<h2>Start editing to see some magic happen!</h2>
<div>user_id: {Store.user_id}</div>
</div>
);
});
export default App;
reference code sandbox link
