Unexpected token - react/js - javascript

I'm trying to run a project, but the same is displaying an error in the console related to a function I have, the error is as follows:

I wonder why this error is happening (I am a beginner in react).

It is a syntax error.
Replace function toggleDrawer = to
const toggleDrawer =

Google OAuth2 Styling issue

I'm new to coding, and trying to build a social media application. I'm using react js in which I'm not able to provide styling to the Google Login Button. I have tried to provide style in various ways like from tweking the parent component to doing changes in style js, but none of it seems to work.
This is Auth.js

ReactJS button loses its functionality when I resize the window

This is the header.component.js file. It renders the header of the component in my react app. I'm trying to make the fontAwesome Icon that contains the "faBars" property:
<Row onClick={onToggleMenu}>
<Col>
<FontAwesomeIcon
icon={faBars}
size="2x"
/>
</Col>
</Row>
open and close the sidebar even when the window gets resized. The problem that I'm having is that although the icon is responsive, it loses its functionality as soon as the window resizes.
This is the entire component:
import React from 'react';
import clsx from 'clsx';
import { connect } from 'react-redux';
import { setSidebarToggleMobile } from '../redux/reducers/theme.reducer';
import HeaderUserbox from '../components/header-user-box.component';
import { FontAwesomeIcon } from '#fortawesome/react-fontawesome';
import { faBell } from '#fortawesome/free-regular-svg-icons';
import { faBars } from '#fortawesome/free-solid-svg-icons';
import { Badge, Row, Col } from 'reactstrap';
// import redux and reducers
import store from "../redux/store"
import { SET_SIDEBAR_TOGGLE } from "../redux/reducers/theme.reducer"
const Header = (props) => {
const { headerShadow, headerBgTransparent } = props;
/** Metodo que ejecuta el toggle del sideber*/
const onToggleMenu = () => {
const isActive = store.getState().sidebar.sidebarToggle;
console.log("isActive: " + isActive);
//Original statement:
store.dispatch({ type: SET_SIDEBAR_TOGGLE, sidebarToggle: !isActive });
//console.log("Store.dispatch: " , store.dispatch({ type: SET_SIDEBAR_TOGGLE, sidebarToggle: !isActive }));
}
return (
<>
<div
className={clsx('app-header', {
'app-header--shadow': headerShadow,
'app-header--opacity-bg': headerBgTransparent
})}>
<Row onClick={onToggleMenu}>
<Col>
<FontAwesomeIcon
icon={faBars}
size="2x"
/>
</Col>
</Row>
<div className="app-header--pane"></div>
<div className="app-header--pane">
<aside className="position-relative" style={{ marginLeft: '-20%' }}>
<Badge
color='success'
pill
style={{
zIndex: 1,
borderRadius: '8px',
height: '12px',
width: '5px',
padding: '6px',
marginBottom: '40px',
marginRight: '-14px',
border: '1px solid white',
boxShadow: '2.5px 2px'
}}
>
{' '}
</Badge>
</aside>
<FontAwesomeIcon
icon={faBell}
size='4x'
style={
{
borderRadius: '8px',
zIndex: -1,
padding: '5%',
margin: '3%',
width: '50px',
backgroundColor: '#d1ffd5',
color: '#03ac13'
}}
/>
<HeaderUserbox />
</div>
</div>
</>
);
};
const mapStateToProps = (state) => ({
headerShadow: state.sidebar.headerShadow,
headerBgTransparent: state.sidebar.headerBgTransparent,
sidebarToggleMobile: state.sidebar.sidebarToggleMobile
});
const mapDispatchToProps = (dispatch) => ({
setSidebarToggleMobile: (enable) => dispatch(setSidebarToggleMobile(enable))
});
export default connect(mapStateToProps, mapDispatchToProps)(Header);
Hello try to prevent the default event sometimes it's fixe
const onToggleMenu = (event) => {
event.preventDefault();
const isActive = store.getState().sidebar.sidebarToggle;
console.log("isActive: " + isActive);
//Original statement:
store.dispatch({ type: SET_SIDEBAR_TOGGLE, sidebarToggle: !isActive });
//console.log("Store.dispatch: " , store.dispatch({ type: SET_SIDEBAR_TOGGLE, sidebarToggle: !isActive }));
}
and you can invoke your function
<Row onClick={(e)=>onToggleMenu(e)}>

It seems you have checked the activeStep wrong.
Maybe the right code must be like the following:
<React.Fragment>
{activeStep !== 0 ?getStepContent(activeStep, addressFormValues, changeAddressFormValue , paymentFormValues, changePaymentFormValue) : getStepContent(activeStep)}
Do you ever consider using Context API?
React Context API
But also you can use create a checkboxValue with useState in Checkout.js and pass setCheckBoxValue to PaymentForm in getStepContent as prop. When checkbox checked trigger setCheckBoxValue and it will trigger parent component's state (Checkbox).

How to use dispatch in nextjs getStaticprops or getServerSideProps

I am new to Next js, I want to call the news api in useEffect and dispatch the news array to my store. then filter it based on the user's input in the search bar in the header. problem is once the use effect data fetching is done and user starts typing rather than filtering the news array the screen gets re-render and the data fetching starts again. how to prevent this re-rendering and save the news array?
I tried to use getStaticprops but useDispatch is not allowed in there.
index.js
import { fetchNews } from "../store/actions/newsActions";
import NewsInfo from "../components/NewsInfo";
import { useDispatch, useSelector } from "react-redux";
import CircularProgress from "#material-ui/core/CircularProgress";
export default function Home() {
const dispatch = useDispatch();
const { news } = useSelector((state) => state.news);
React.useEffect(() => {
dispatch(fetchNews());
}, []);
return (
<>
{/* this wrapper cmp will make each headline uniquely accessible */}
{news?.articles ? (
news.articles.map((article) => (
<React.Fragment key={article.publishedAt}>
<NewsInfo headlines={article} />

))
) : (

export const rootDispatch = store.dispatch;

ReactJS TypeError: this.props. is not a function

I'm building an application, where there is a form presented with different steps. In all the steps but one, I manage to provide the necessary functions as props to make some operations such as 'handleNext', 'handleBack' or 'handleChange'.
Nevertheless, in the last step, represented in the class SuccessForm, when I try to execute the 'handleDownload' function, I get the following error:
TypeError: this.props.handleDownload is not a function
Here it is the SuccessForm.js class:
export class SuccessForm extends Component {

}
download = e => {
e.preventDefault();
this.props.handleDownload();
}
render() {

Try calling super(props) in the constructor:
constructor(props) {
super(props);
}
and passing function with this instance (this.handleDownload) as it is a class property:
<SuccessForm handleDownload={this.handleDownload} />
Update:
You have a bug on the last step when you not passing a property:
activeStep === steps.length ? <SuccessForm handleDownload={this.handleDownload}/>
Assuming that you have a class in your parent Component, what you're missing is the this keyword in the function reference...
case 3:
return <SuccessForm
handleDownload={this.handleDownload}
/>;
