opening devtool causes webpage to reload (Google Chrome) - reactjs

I'm having a issue and im not sure the problem is chrome, react or macOs
When i open devtools my component rerender. I have simple code about redux-persist
Summary: Im trying to open second browser when Page1 renders if user closes Page2, a button inside Page1 will be active to open Page2 on second tab.
When user closes/refreshs Page1 tab Page2 tab will also close and clear the persist:root
Im using:

Edit: Not only my component rerender it starts from index.js

I found the answer it is not about react. I'm using extension called "Awesome Color Picker" when i disable this extension the problem solved.

It looks like you're importing useWeb3 wrong:
const web3 = useWeb3();
But you export it like:
export {useWeb3};
So now you would have to call it like: web3.useWeb3()
Is this code you found at a tutorial somewhere? It's hard to follow...

React-Router-Dom <Link> not render page

I'm building a practice app that uses Unsplash to render users photos. I'm using React and Redux. With react-router-dom, I'm trying to follow the docs but I find it very confusing to set up. Here's what I have so far. When I click on a result out of a returned list of results from a search, I want it to render a user page profile.
index.js (make sure I have react-router-do set up correctly):
import React from 'react';
import ReactDOM from 'react-dom';
import { BrowserRouter } from 'react-router-dom';
import './index.css';
import App from './App';
// import store from './app/store';
import { Provider } from 'react-redux';
import { createStore, applyMiddleware, compose } from "redux";
import thunk from "redux-thunk";
import reducers from "./app/reducers/rootReducer";
import * as serviceWorker from './serviceWorker';
const storeEnhancers = window.__REDUX_DEVTOOLS_EXTENSION_COMPOSE__ || compose;
const store = createStore(reducers, storeEnhancers(applyMiddleware(thunk)));
ReactDOM.render(
<React.StrictMode>
<Provider store={store}>
<BrowserRouter>
<App />
</BrowserRouter>
</Provider>
</React.StrictMode>,
document.getElementById("root")
);
Top component App
import React from "react";
import { BrowserRouter as Router, Route } from "react-router-dom";
import Images from "./app/components/Images";
import Search from "./app/components/Search";
import UserProfile from "./app/components/UserProfile";
import "./App.css";
function App() {
return (
<>
<Search />
<Images />
<Router>
<Route link="/userProfile">
<UserProfile />
</Route>
</Router>
</>
);
}
export default App;
search (parent component to searchResults where exists):
import React, { useState, useEffect } from "react";
import { connect } from "react-redux";
import { queryAction } from "../actions/queryAction";
import SearchResults from "./SearchResults";
const Search = (props) => {
const [query, setQuery] = useState("");
console.log(props.searches);
const searchPhotos = async (e) => {
e.preventDefault();
console.log("submitting form");
props.queryAction(query);
};
const showUsers = (user, e) => {
e.preventDefault()
console.log(user)
};
return (
<>
<form className="form" onSubmit={searchPhotos}>
<label className="label" htmlFor="query">
{" "}
</label>
<input
type="text"
name="query"
className="input"
placeholder={`Try "dog" or "apple"`}
value={query}
onChange={(e) => setQuery(e.target.value)}
/>
<button type="submit" className="button">
Search
</button>
</form>
<SearchResults results={props.searches} showUsers={showUsers} />
</>
);
};
const mapStateToProps = (state) => {
return {
searches: state.searches,
};
};
const mapDispatchToProps = (dispatch) => {
return {
queryAction: (entry) => dispatch(queryAction(entry)),
};
};
export default connect(mapStateToProps, mapDispatchToProps)(Search);
searchResults:
import React from "react";
import { BrowserRouter as Router, Link } from "react-router-dom";
import { getUserAction } from "../actions/getUserAction";
import { connect } from "react-redux";
const SearchResults = (props) => {
const { results } = props.results.searches;
const handleClick = (result, e) => {
e.preventDefault();
props.getUser(result.username);
};
return (
<>
{results &&
results.map((result, id) => {
return (
<div key={id}>
<Router>
<Link to="/userProfile" onClick={(e) => handleClick(result, e)}>
{result.username}
</Link>
</Router>
</div>
);
})}
</>
);
};
const mapDispatchToProps = (dispatch) => {
return {
getUser: (query) => dispatch(getUserAction(query)),
};
};
export default connect(null, mapDispatchToProps)(SearchResults);
and finally the UserProfile component:
import React from 'react';
import { connect } from 'react-redux';
const UserProfile = props => {
console.log(props)
return (
<div>
</div>
);
}
const mapStateToProps = state => {
return {
user: state.users
}
}
export default connect(mapStateToProps, null)(UserProfile);
app component
import React from "react";
import { Switch, Route } from "react-router-dom";
import Images from "./app/components/Images";
import Search from "./app/components/Search";
import UserProfile from "./app/components/UserProfile";
import "./App.css";
function App() {
return (
<>
<Search />
<Images />
<Switch>
<Route path="/userProfile/:username">
<UserProfile />
</Route>
</Switch>
</>
);
}
export default App;
SearchResults component
import React from "react";
import { Link } from "react-router-dom";
const SearchResults = (props) => {
const { results } = props.results.searches;
const handleClick = (result, e) => {
e.preventDefault();
props.getUser(result.username);
};
return (
<>
{results &&
results.map((result, id) => {
return (
<div key={id}>
<Link to={`/userProfile/${result.username}`}>
{result.username}
</Link>
</div>
);
})}
</>
);
};
export default SearchResults;
UserProfile component
import React, { useEffect } from 'react';
import { connect } from 'react-redux';
import { getUserAction } from "../actions/getUserAction";
const UserProfile = props => {
useEffect(() => {
props.getUserAction(props.match.params.username)
},[])
console.log(props)
return (
<div>
{props.user
? <div>{user.username}</div>
: <div>Loading...</div>
}
</div>
);
}
const mapStateToProps = state => {
return {
user: state.users
}
}
const mapDispatchToProps = (dispatch) => {
return {
getUser: (query) => dispatch(getUserAction(query)),
};
};
export default connect(mapStateToProps, mapDispatchToProps)(UserProfile);
Edit: Add a param to your link and remove the onclick. Update the Route to expect a :username param. You can access the param through props in UserProfile component.
Make sure to perform the action or access state when mounting the UserProfile component so you have some data when it renders.
Edit 2: Added UserProfile component to answer. You want to dispatch your action when the component is mounting. Also, set a ternary to show "Loading..." if state.user isn't done being fetched.

Navbar is not re-rendering on router location change

I want to display userName and changed the button text to 'logout' from 'login' in Navbar(nav component) when user is logged in. I tired to re-render the Nav Component by pushing the router history location to homepage on user logged in.
this.props.history.push('/')
Then User can successfully log in, user data is saved in localStorage and the router location is changed. data is saved in localStorage, but the component is not re-rendering.
Here is what I have tried.
tried to downgrade 'connected-react-router' to 'v6.0.0' but it threw me some errors. so put it back to the latest version '^6.4.0'.
tried to add Navbar code in App.js which is the parents component.
But the app.js itself is not re-rendering either on user logged in.
app.js

I am expecting Nav component to be re-rendered when router location changes.

react-router-dom: ^4.3.1
redux: ^4.0.0

I fixed it by saving 'isLoggedIn' state in redux store. And to persist the state from redux store on page refresh, I used 'redux-persist'.
Now Nav component is re-rendering on router location change and the userName data is saved even on page refresh.

const auth = (state = initialState, action) => {

React Router v4 and loadable-components always rendering same Component even though the route matches other

I've got a Standard React-Redux Application with react router v4, webpack 4 and I'm trying to perform lazy loading of components via loadable-components library, so webpack can create chunks and load them on demand. The problems seems it's always rendering the Dashboard (refer code below) Component inside the <Switch>, no matter the route.
I don't understand the cause. I found a similar problem: React-Router v4 rendering wrong component but matching correctly but it follows a different pattern and I can't or don't understand how to apply that solution into my issue.
I'm posting The main AppContainer and the routes file:
AppContainer.js:
import React, { Component } from 'react'
import PropTypes from 'prop-types'
import { Provider } from 'react-redux'
import ReduxToastr from 'react-redux-toastr'
import 'react-redux-toastr/src/styles/index.scss'
import { Offline, Online } from 'react-detect-offline'
import Footer from 'components/Footer/'
import { Modal, ModalHeader, ModalBody } from 'reactstrap'
import { Translate } from 'react-redux-i18n'
import { PersistGate } from 'redux-persist/integration/react'
import { Router, Switch, Route } from 'react-router-dom'
import PrivateRoute from 'components/PrivateRoute'
import { Dashboard, PasswordReset, PasswordResetEdit, SignIn } from 'routes'
// Layout
import CoreLayout from 'layouts/CoreLayout'
class AppContainer extends Component {
static propTypes = {
history: PropTypes.object.isRequired,
persistor: PropTypes.object.isRequired, // redux-persist
store : PropTypes.object.isRequired
}
render () {
const { history, store, persistor } = this.props
const opened = true
const toastrDefaultTimeout = 8000
const newToastrAlwaysOnTop = false
return (
<div>
<Online>
<Provider store={store}>
<PersistGate loading={null} persistor={persistor}>
<div style={{ height: '100%' }}>
<ReduxToastr

}
}
export default AppContainer
routes/index.js:
// We only need to import the modules necessary for initial render
import loadable from 'loadable-components'
import { hot } from 'react-hot-loader'
// Component split-code (lazy load)
let Dashboard,
SignIn,
PasswordReset,
PasswordResetEdit
// Needed for HMR
if (__DEV__) {
Dashboard = hot(module)(loadable(() => import('./Dashboard')))
PasswordReset = hot(module)(loadable(() => import('./PasswordReset')))
PasswordResetEdit = hot(module)(loadable(() => import('./PasswordResetEdit')))
SignIn = hot(module)(loadable(() => import('./SignIn')))
} else {
Dashboard = loadable(() => import('./Dashboard'))
SignIn = loadable(() => import('./SignIn'))
PasswordReset = loadable(() => import('./PasswordReset'))
PasswordResetEdit = loadable(() => import('./PasswordResetEdit'))
}
export { Dashboard, PasswordReset, PasswordResetEdit, SignIn }
And for anyone curious, here is the PrivateRoute component:
import React, { Component } from 'react'
import PropTypes from 'prop-types'
import { Route, Redirect } from 'react-router-dom'
import { connect } from 'react-redux'
import { validateSession } from 'modules/sessions/session'
const mapStateToProps = state => ({
session: state.session
})
const mapDispatchToProps = (dispatch) => {
return {
validateSession: () => { dispatch(validateSession()) }
}
}
class PrivateRoute extends Component {
componentDidMount () {
this.props.validateSession(this.props.persistor)
}
render () {
const { component: Component, session, ...rest } = this.props
return (
<Route {...rest} render={(routeProps) =>
this.props.session.userSignedIn ? <Component {...routeProps} />
: <Redirect to={{
pathname: '/sign-in',
state: { from: routeProps.location }
}} />
}
/>)
}
}
PrivateRoute.propTypes = {
component: PropTypes.func.isRequired,
persistor: PropTypes.object.isRequired,
session: PropTypes.object.isRequired,
validateSession: PropTypes.func.isRequired
}
export default connect(mapStateToProps, mapDispatchToProps)(PrivateRoute)
If I remove the if (_DEV_) block in routes/index.js and always do it like the 'else' block everything works okay, however I lose HMR, meaning I have to refresh the browser to see code changes take effect.
Edit
For anyone wandering where the history prop comes from:
Main app entry point (in webpack.config.js). src/main.js:

const MOUNT_NODE = document.getElementById('root')
let render = () => {

}
// Wrap render in try/catch
