I have tried using two different libraries to handle this issue and both time I get the same behavior.
Libraries tried: OvermindJS, Hookstate
When I click the button I can see the state change is beeing logged in the console but the component will only re-render on the second click
If I change page:
click Home
click Page1
click No Funds
Then it will show 1$
If I click straightway the No Funds button without changing page (first action on page) then the button will not re-render until it is clicked twice.

How can I get the button on change on the first click?
I am trying to do TODO application using Firebase. I need to obtain lists from firebase. But I face the above error. In Firebase i have added "todos" and "lists". And lists must combine some todos.
Can somebody please help me? I am not good at this.
Here you can see my code:
App.jsx

export default function App() {
const [lists, setLists ] = useState([]);
const [todos, setTodos ] = useState([]);
useEffect(() => {
get('lists').then(setLists);
get('todos').then(setTodos);
}, []);
return (
<DBContext.Provider value={{lists, todos}}>
<div className="app">
<AppDrawer
lists={lists}
/>
<AppContent>
<Switch>
<Route path="/:listId" component={TodoList} />
</Switch>
</AppContent>
</div>
</DBContext.Provider>
);
}
AppDrawer.jsx

I have a React ecommerce site that is currently integrated with Stripe. When a successful payment is submitted, the cart is emptied (managed in localStorage), however the Cart quantity in the Navbar isn't resetting to 0.
The cart quantity is being managed in state in the <App /> component, setQty. The stripe payment is submitted in the <PaymentForm> component which is nested 4 components deep:
<App /> > <Checkout /> > <PaymentForm /> > <CheckoutForm />
In CheckoutForm, I'm using setQty({quantity: 0}); which I thought would pass "0" up to <App /> and reset the Cart quantity, instead I get an error of "Unhandled Rejection (TypeError): setQty is not a function". Why is this? How can I get this to work? Also, is there an easier way of resetting the Cart without passing props through so many components?
A breakdown of each component so you can see how I'm passing setQty through each component:

Screenshot of my file structure
In the App component, you need to pass setQty as below. Props that are mentioned in the Route component would not be transmitted to the component by itself, and we need to use the render function to pass props.
<Route path="/Checkout" render={(props) => <Checkout setQty={setQty} {...props}/>
I have custom user menu
import React from "react";
import { UserMenu, MenuItemLink} from "react-admin";
import SettingsIcon from "#material-ui/icons/Settings";
import jwt from "jwt-decode";
const AdminUserMenu = ({ logout }) => {
var user = jwt(localStorage.getItem("token"));
return (
<UserMenu>
<MenuItemLink
to={"/Admins/" + user.id}
primaryText="Profile"
leftIcon={<SettingsIcon />}
/>
{logout}
</UserMenu>
);
};
export default AdminUserMenu;
const AdminAppBar = (props) => (
<AppBar {...props} userMenu={<AdminUserMenu />} />
);
Profile link works. But logout button does nothing. How can I make it work so that user could logout?
Try this:
const AdminUserMenu = (props) => {
var user = jwt(localStorage.getItem("token"));
return (
<UserMenu {...props} >
<MenuItemLink
to={"/Admins/" + user.id}
primaryText="Profile"
leftIcon={<SettingsIcon />}
/>
</UserMenu>
);
};
I had the same behavior that you did using the latest version. The above code from MaxAlex also didn't work for some reason.
I was able to get it work work as follows. Notice the placement of the {logout} in the ConfigurationMenu object versus in the CustomUserMenu.
import * as React from 'react';
import { forwardRef } from 'react';
import { AppBar, UserMenu, MenuItemLink, useTranslate } from 'react-admin';
import Typography from '#material-ui/core/Typography';
import SettingsIcon from '#material-ui/icons/Settings';
import { makeStyles } from '#material-ui/core/styles';
import Logo from '../Logo';
const useStyles = makeStyles({
title: {
flex: 1,
textOverflow: 'ellipsis',
whiteSpace: 'nowrap',
overflow: 'hidden',
},
spacer: {
flex: 1,
}
});
const ConfigurationMenu = ({logout, props}) => {
const translate = useTranslate();
return (
<div>
<MenuItemLink
to="/profile"
primaryText={translate("cw.profile.title")}
leftIcon={<SettingsIcon />}
{...props}
/>
{logout}
</div>
);
};
const CustomUserMenu = (props) => (
<UserMenu {...props} >
<ConfigurationMenu />
</UserMenu>
);
const CustomAppBar = (props) => {
const classes = useStyles();
return (
<AppBar {...props} elevation={1} userMenu={<CustomUserMenu />}>
<Typography
variant="h6"
color="inherit"
className={classes.title}
id="react-admin-title"
/>
<Logo />
<span className={classes.spacer} />
</AppBar>
);
};
export default CustomAppBar;
The new react-router syntax uses the Link component to move around the routes. But how could this be integrated with material-ui?
In my case, I'm using tabs as the main navigation system, So in theory I should have something like this:
const TabLink = ({ onClick, href, isActive, label }) =>
<Tab
label={label}
onActive={onClick}
/>
export default class NavBar extends React.Component {
render () {
return (
<Tabs>
<Link to="/">{params => <TabLink label="Home" {...params}/>}</Link>
<Link to="/shop">{params => <TabLink label="shop" {...params}/>}</Link>
<Link to="/gallery">{params => <TabLink label="gallery" {...params}/>}</Link>
</Tabs>
)
}
}
But when it renders, material-ui throws an error that the child of Tabs must be a Tab component. What could be the way to proceed? How do I manage the isActive prop for the tab?
Thanks in advance
Another solution (https://codesandbox.io/s/l4yo482pll) with no handlers nor HOCs, just pure react-router and material-ui components:
import React, { Fragment } from "react";
import ReactDOM from "react-dom";
import Tabs from "#material-ui/core/Tabs";
import Tab from "#material-ui/core/Tab";
import { Switch, Route, Link, BrowserRouter, Redirect } from "react-router-dom";
function App() {
const allTabs = ['/', '/tab2', '/tab3'];
return (
<BrowserRouter>
<div className="App">
<Route
path="/"
render={({ location }) => (
<Fragment>
<Tabs value={location.pathname}>
<Tab label="Item One" value="/" component={Link} to={allTabs[0]} />
<Tab label="Item Two" value="/tab2" component={Link} to={allTabs[1]} />
<Tab
value="/tab3"
label="Item Three"
component={Link}
to={allTabs[2]}
/>
</Tabs>
<Switch>
<Route path={allTabs[1]} render={() => <div>Tab 2</div>} />
<Route path={allTabs[2]} render={() => <div>Tab 3</div>} />
<Route path={allTabs[0]} render={() => <div>Tab 1</div>} />
</Switch>
</Fragment>
)}
/>
</div>
</BrowserRouter>
);
}
const rootElement = document.getElementById("root");
ReactDOM.render(<App />, rootElement);
My instructor helped me with using React Router 4.0's withRouter to wrap the Tabs component to enable history methods like so:
import React, {Component} from "react";
import {Tabs, Tab} from 'material-ui';
import { withRouter } from "react-router-dom";
import Home from "./Home";
import Portfolio from "./Portfolio";
class NavTabs extends Component {
handleCallToRouter = (value) => {
this.props.history.push(value);
}
render () {
return (
<Tabs
value={this.props.history.location.pathname}
onChange={this.handleCallToRouter}
>
<Tab
label="Home"
value="/"
>
<div>
<Home />
</div>
</Tab>
<Tab
label="Portfolio"
value="/portfolio"
>
<div>
<Portfolio />
</div>
</Tab>
</Tabs>
)
}
}
export default withRouter(NavTabs)
Simply add BrowserRouter to index.js and you're good to go.
The error you are seeing from material-ui is because it expects to have a <Tab> component rendered as direct child of <Tabs> component.
Now, here is a way that I've found to integrate the link into the <Tabs> component without loosing the styles:
import React, {Component} from 'react';
import {Tabs, Tab} from 'material-ui/Tabs';
import {Link} from 'react-router-dom';
export default class MyComponent extends Component {
render() {
const {location} = this.props;
const {pathname} = location;
return (
<Tabs value={pathname}>
<Tab label="First tab" containerElement={<Link to="/my-firs-tab-view" />} value="/my-firs-tab-view">
{/* insert your component to be rendered inside the tab here */}
</Tab>
<Tab label="Second tab" containerElement={<Link to="/my-second-tab-view" />} value="/my-second-tab-view">
{/* insert your component to be rendered inside the tab here */}
</Tab>
</Tabs>
);
}
}
To manage the 'active' property for the tabs, you can use the value property in the <Tabs> component and you also need to have a value property for each tab, so when both of the properties match, it will apply the active style to that tab.
Solution with Tab highlight, Typescript based and works well with react-route v5:
Explanation: <Tab/> here work as a link to React router. Values in <Tab/> to={'/all-event'} and value={'/all-event'} should be same in order to highlgiht
import { Container, makeStyles, Tab, Tabs } from '#material-ui/core';
import React from 'react';
import {
Link,
Route,
Switch,
useLocation,
Redirect,
} from 'react-router-dom';
import AllEvents from './components/AllEvents';
import UserEventsDataTable from './components/UserEventsDataTable';
const useStyles = makeStyles(() => ({
container: {
display: 'flex',
justifyContent: 'center',
},
}));
function App() {
const classes = useStyles();
const location = useLocation();
return (
<>
<Container className={classes.container}>
<Tabs value={location.pathname}>
<Tab
label='All Event'
component={Link}
to={`/all-event`}
value={`/all-event`}
/>
<Tab
label='User Event'
component={Link}
to={`/user-event`}
value={`/user-event`}
/>
</Tabs>
</Container>
<Switch>
<Route path={`/all-event`}>
<AllEvents />
</Route>
<Route path={`/user-event`}>
<UserEventsDataTable />
</Route>
<Route path={`/`}>
<Redirect from='/' to='/all-event' />
</Route>
</Switch>
</>
);
}
export default App;
Here's another solution, using the beta of Material 1.0 and adding browser Back/Forward to the mix:
import React from 'react';
import PropTypes from 'prop-types';
import { withStyles } from 'material-ui/styles';
import AppBar from 'material-ui/AppBar';
import Tabs, { Tab } from 'material-ui/Tabs';
import { withRouter } from "react-router-dom";
import Home from "./Home";
import Portfolio from "./Portfolio";
function TabContainer(props) {
return <div style={{ padding: 20 }}>{props.children}</div>;
}
const styles = theme => ({
root: {
flexGrow: 1,
width: '100%',
marginTop: theme.spacing.unit * 3,
backgroundColor: theme.palette.background.paper,
},
});
class NavTabs extends React.Component {
state = {
value: "/",
};
componentDidMount() {
window.onpopstate = ()=> {
this.setState({
value: this.props.history.location.pathname
});
}
}
handleChange = (event, value) => {
this.setState({ value });
this.props.history.push(value);
};
render() {
const { classes } = this.props;
const { value } = this.state;
return (
<div className={classes.root}>
<AppBar position="static" color="default">
<Tabs
value={value}
onChange={this.handleChange}
scrollable
scrollButtons="on"
indicatorColor="primary"
textColor="primary"
>
<Tab label="Home" value = "/" />
<Tab label="Portfolio" value = "/portfolio"/>
</Tabs>
</AppBar>
{value === "/" && <TabContainer>{<Home />}</TabContainer>}
{value === "/portfolio" && <TabContainer>{<Portfolio />}</TabContainer>}
</div>
);
}
}
NavTabs.propTypes = {
classes: PropTypes.object.isRequired,
};
export default withRouter(withStyles(styles)(NavTabs));
You can use browserHistory instead of React-Router Link component
import { browserHistory } from 'react-router'
// Go to /some/path.
onClick(label) {
browserHistory.push('/${label}');
}
// Example for Go back
//browserHistory.goBack()
<Tabs>
<Tab
label={label}
onActive={() => onClick(label)}
/>
</Tabs>
As you see you can simply push() your target to the browserHistory
As #gkatchmar says you can use withRouter high-order component but you can also use context API. Since #gkatchmar showed withRouter already I will only show context API. Bear in mind that this is an experimental API.

import React, {Component} from "react";
import {Tabs, Tab} from 'material-ui';
import * as PropTypes from "prop-types";
export class NavTabs extends Component {
constructor(props) {
super(props);
}
static contextTypes = {
router: PropTypes.object
}
handleChange = (event: any , value: any) => {
this.context.router.history.push(value);
};
render () {
return (
<Tabs

)
}
}
Here's a simple solution using the useLocation hook. No state needed. React router v5 though.
import { Tab, Tabs } from '#material-ui/core';
import { matchPath, NavLink, useLocation } from 'react-router-dom';
const navItems = [
{
id: 'one',
path: '/one',
text: 'One',
},
{
id: 'two',
path: '/two',
text: 'Two',
},
{
id: 'three',
path: '/three',
text: 'Three',
},
];
export default function Navigation() {
const { pathname } = useLocation();
const activeItem = navItems.find((item) => !!matchPath(pathname, { path: item.path }));
return (
<Tabs value={activeItem?.id}>
{navItems.map((item) => (
<Tab key={item.id} value={item.id} label={item.text} component={NavLink} to={item.path} />
))}
</Tabs>
);
}
<BrowserRouter>
<div className={classes.root}>
<AppBar position="static" color="default">
<Tabs
value={this.state.value}
onChange={this.handleChange}
indicatorColor="primary"
textColor="primary"
fullWidth
>
<Tab label="Item One" component={Link} to="/one" />
<Tab label="Item Two" component={Link} to="/two" />
</Tabs>
</AppBar>
<Switch>
<Route path="/one" component={PageShell(ItemOne)} />
<Route path="/two" component={PageShell(ItemTwo)} />
</Switch>
</div>
I've created this hook to help control the tabs and generate the default value that catches from the location URL.
const useTabValue = (array, mainPath = "/") => {
const history = useHistory();
const { pathname } = useLocation();
const [value, setValue] = useState(0);
const pathArray = pathname.split("/");
function handleChange(_, nextEvent) {
setValue(nextEvent);
history.push(`${mainPath}/${array[nextEvent]}`);
}
const findDefaultValue = useCallback(() => {
return array.forEach((el) => {
if (pathArray.indexOf(el) > 0) {
setValue(array.indexOf(el));
return;
}
});
}, [pathArray, array]);
useEffect(() => {
findDefaultValue();
}, [findDefaultValue]);
return {
handleChange,
value,
};
};
then I have used it like this :
const NavigationBar = () => {
const classes = useStyles();
const allTabs = useMemo(() => ["home", "search"]);
const { handleChange, value } = useTabValue(allTabs, "/dashboard");
return (
<div className={classes.navBarContainer}>
<Tabs
centered
value={value}
variant="fullWidth"
onChange={handleChange}
className={classes.navBar}
>
<Tab color="textPrimary" icon={<HomeIcon />} />
<Tab color="textPrimary" icon={<ExploreIcon />} />
</Tabs>
</div>
);
};
I solved this in a much easier fashion (I was surprised this worked so well - maybe there's a problem I haven't found out). I'm using Router 6 and React 17 (I know these packages are newer).
In any case, I just used the useNavigate hook in the handleChange function. Thus, now there is NO need for Switch and the code becomes much simpler. See below:
let navigate = useNavigate();
const [selection, setSelection] = useState();
const handleChange = (event, newValue) => {
setSelection(newValue);
navigate(`${newValue}`);
}
return (
<Tabs value={selection} onChange={handleChange}>
<Tab label="Products" value="products" />
<Tab label="Customers" value="customers" />
<Tab label="Invoices" value="invoices" />
</Tabs>
);
}
The handleChange function updates 'selection' which controls the display of the tabs, and also navigates to the right path.
if you set the component somewhere in your React space, and set correctly a :style route (as explained by React Router: https://reactrouter.com/docs/en/v6/getting-started/overview), you can also control in which area of the page will the content be rendered. Hope it helps somebody!
I got it working this way in my app:
import React, {useEffect, useRef} from 'react';
import PropTypes from 'prop-types';
import {makeStyles} from '#material-ui/core/styles';
import AppBar from '#material-ui/core/AppBar';
import Tabs from '#material-ui/core/Tabs';
import Tab from '#material-ui/core/Tab';
import Typography from '#material-ui/core/Typography';
import Box from '#material-ui/core/Box';
import Container from "#material-ui/core/Container";
import {Link} from "react-router-dom";
import MenuIcon from "#material-ui/icons/Menu";
import VideoCallIcon from "#material-ui/icons/VideoCall";
const docStyles = makeStyles(theme => ({
root: {
display: 'flex',
'& > * + *': {
marginLeft: theme.spacing(2),
},
},
appBarRoot: {
flexGrow: 1,
},
headline: {
marginTop: theme.spacing(2),
},
bodyCopy: {
marginTop: theme.spacing(1),
fontSize: '1.2rem',
},
tabContents: {
margin: theme.spacing(3),
},
}));
function TabPanel(props) {
const {children, value, index, classes, ...other} = props;
return (
<div
role="tabpanel"
hidden={value !== index}
id={`simple-tabpanel-${index}`}
aria-labelledby={`simple-tab-${index}`}
{...other}
>
{value === index && (
<Container>
<Box className={classes.tabContents}>
{children}
</Box>
</Container>
)}
</div>
);
}
function a11yProps(index) {
return {
id: `simple-tab-${index}`,
'aria-controls': `simple-tabpanel-${index}`,
};
}
function TabOneContents(props) {
const {classes} = props;
return (
<>
<Typography variant="h4" component={'h1'} className={classes.headline}>
Headline 1
</Typography>
<Typography variant="body1" className={classes.bodyCopy}>
Body Copy 1
</Typography>
</>
)
}
function TabTwoContents(props) {
const {classes} = props;
const nurseOnboardingPath = '/navigator/onboarding/' + Meteor.userId() + '/1';
return (
<>
<Typography variant="h4" component={'h1'} className={classes.headline}>
Headline 2
</Typography>
<Typography variant="body1" className={classes.bodyCopy}>
Body Copy 2
</Typography>
</>
)
}
export default function MUITabPlusReactRouterDemo(props) {
const {history, match} = props;
const propsForDynamicClasses = {};
const classes = docStyles(propsForDynamicClasses);
const [value, setValue] = React.useState(history.location.pathname.includes('/tab_2') ? 1 : 0);
const handleChange = (event, newValue) => {
setValue(newValue);
const pathName = '/' + (value == 0 ? 'tab_1' : 'tab_2');
history.push(pathName);
};
return (
<div className={classes.appBarRoot}>
<AppBar position="static" color="transparent">
<Tabs value={value} onChange={handleChange} aria-label="How It Works" textColor="primary">
<Tab label="Tab 1" {...a11yProps(0)} />
<Tab label="Tab 2" {...a11yProps(1)} />
</Tabs>
</AppBar>
<TabPanel value={value} index={0} classes={classes}>
<TabOneContents classes={classes}/>
</TabPanel>
<TabPanel value={value} index={1} classes={classes}>
<TabTwoContents classes={classes}/>
</TabPanel>
</div>
);
}
...and in React Router:
[.....]
<Route exact path="/tab_1"
render={(routeProps) =>
<MUITabPlusReactRouterDemo history={routeProps.history}
/>
}/>
<Route exact path="/tab_2"
render={(routeProps) =>
<MUITabPlusReactRouterDemo history={routeProps.history} />
}/>
[.....]
