my history.push is not working, I need to refresh the browser for him work.
I am new with react and,
what I am doing wrong?
Can anyone help me with it??

code below:
const history = useHistory();
const handleSignIn = useCallback(
async data => {
try {
await getToken(data.username, data.password);
history.push('/dashboard');
} catch (err) {
if (err instanceof Yup.ValidationError) {
const errors = getValidationErrors(err);
if (formRef.current) {
formRef.current.setErrors(errors);
}
}
}
},
[getToken, history],
);
return (
<Container>
<Content>
<h1>Faça seu login</h1>
<Form ref={formRef} onSubmit={handleSignIn}>
<Input name="username" placeholder="Usuário" />
<Input name="password" type="password" placeholder="Senha" />
<Button type="submit">Entrar</Button>
</Form>
index of routes below :
import React from 'react';
import { Switch } from 'react-router-dom';
import Route from './Route';
import Register from '../pages/Register';
import SignIn from '../pages/SignIn';
import SignUp from '../pages/SignUp';
import Dashboard from '../pages/Dashboard';
export default function Routes() {
return (
<Switch>

</Switch>
);
}
this is my code of private routes:
export default function Route({
isPrivate = false,
component: Component,
...rest
}) {
const { user } = useAuth();
return (
<ReactDOMRoute
{...rest}
render={({ location }) => {
return isPrivate === !!user ? (
<Component />
) : (
<Redirect
to={{
pathname: isPrivate ? '/' : '/dashboard',
state: { from: location },
}}
/>
);
}}
/>
);
}
My App.js below:
import Routes from './routes';
export default function App() {
return (
<BrowserRouter>
<AppProvider>

The Switch doesn't handle rendering anything other than Route and Redirect components. If you want to "nest" like this then you need to wrap each in generic routes, but that is completely unnecessary.
Your login component also doesn't handle redirecting back to any "home" page or private routes that were originally being accessed.
Solution
react-router-dom v5
Create a PrivateRoute component that consumes your auth context.
const PrivateRoute = (props) => {
const location = useLocation();
const { authLogin } = useContext(globalC);
if (authLogin === undefined) {
return null; // or loading indicator/spinner/etc
}
return authLogin ? (
<Route {...props} />
) : (
<Redirect
to={{
pathname: "/login",
state: { from: location }
}}
/>
);
};
Update your Login component to handle redirecting back to the original route being accessed.
export default function Login() {
const location = useLocation();
const history = useHistory();
const { authLogin, loginData } = useContext(globalC);
useEffect(() => {
if (authLogin) {
const { from } = location.state || { from: { pathname: "/" } };
history.replace(from);
}
}, [authLogin, history, location]);
return (
<div
style={{ height: "100vh" }}
className="d-flex justify-content-center align-items-center"
>
<button type="button" onClick={loginData} className="btn btn-primary">
Login
</button>
</div>
);
}
Render all your routes in a "flat list"
function Routes() {
return (
<BrowserRouter>
<Switch>
<PrivateRoute path="/dashboard" component={Dashboard} />
<PrivateRoute path="/About" component={About} />
<Route path="/login" component={Login} />
<Route component={PageNotFound} />
</Switch>
</BrowserRouter>
);
}
react-router-dom v6

Here is an easy react-router v6 protected route. I have put all the routes I want to protect in a routes.js:-
const routes = [{ path: "/dasboard", name:"Dashboard", element: <Dashboard/> }]
To render the routes just map them as follows: -
<Routes>
{routes.map((routes, id) => {
return(
<Route
key={id}
path={route.path}
exact={route.exact}
name={route.name}
element={
localStorage.getItem("token") ? (
route.element
) : (
<Navigate to="/login" />
)
}
)
})
}
</Routes>
If you want an easy way to implement then use Login in App.js, if user is loggedin then set user variable. If user variable is set then start those route else it will stuck at login page. I implemented this in my project.
return (
<div>
<Notification notification={notification} type={notificationType} />
{
user === null &&
<LoginForm startLogin={handleLogin} />
}
{
user !== null &&
<NavBar user={user} setUser={setUser} />
}
{
user !== null &&
<Router>
<Routes>
<Route exact path="/" element={<Home />} />
<Route exact path="/adduser" element={<AddUser />} /> />
<Route exact path="/viewuser/:id" element={<ViewUser />} />
</Routes>
</Router>
}
</div>
)

showing state as null of useLocation hook. want to know why and how can I fix it? [duplicate]

Would like to add highlight never forget to give path as prop to ProtectedRoute, else it will not work.
Here is an easy react-router v6 protected route. I have put all the routes I want to protect in a routes.js:-
const routes = [{ path: "/dasboard", name:"Dashboard", element: <Dashboard/> }]
To render the routes just map them as follows: -
<Routes>
{routes.map((routes, id) => {
return(
<Route
key={id}
path={route.path}
exact={route.exact}
name={route.name}
element={
localStorage.getItem("token") ? (
route.element
) : (
<Navigate to="/login" />
)
}
)
})
}
</Routes>
If you want an easy way to implement then use Login in App.js, if user is loggedin then set user variable. If user variable is set then start those route else it will stuck at login page. I implemented this in my project.
return (
<div>
<Notification notification={notification} type={notificationType} />
{
user === null &&
<LoginForm startLogin={handleLogin} />
}
{
user !== null &&
<NavBar user={user} setUser={setUser} />
}
{
user !== null &&
<Router>
<Routes>
<Route exact path="/" element={<Home />} />
<Route exact path="/adduser" element={<AddUser />} /> />
<Route exact path="/viewuser/:id" element={<ViewUser />} />
</Routes>
</Router>
}
</div>
)

Problem when reloading page using react-router-dom

I managed to make a private route and navigate to different pages using react-router-dom. How ever, when I navigate to a page and reload it, it first goes to /login for half a second and the reloads the page correctly. How can I prevent this unwanted behavior and improve my routing?
Here are my routes:
<Router>
<Route
path="/"
component={() =>
!auth ? <Redirect to="/login" /> : <Redirect to={path} />
}
/>
<Route exact path="/home" component={Home} />
<Route exact path="/dashboard" component={Dashboard} />
<Route exact path="/login" component={RedirectPage} />
</Router>
This is the full component:
import {
Route,
BrowserRouter as Router,
Link,
Redirect,
} from "react-router-dom";
import { Container, Button } from "#material-ui/core/";
import Login from "./Login";
import { useContext,useState } from "react";
import { UserContext } from "../App";
import { signOut } from "../Storage/Auth";
const Routes = () => {
const { auth, setAuth, logging } = useContext(UserContext);
const [path,setPath] = useState("/home")
const handleSignOut = () => {
signOut(setAuth);
console.log("Auth", auth);
};
const Home = () => {
console.log("Home");
return (
<Container>
<h1>Welcome</h1>
<Link to="/">
<Button onClick={handleSignOut}> Log Out</Button>
</Link>
<Link to="/dashboard">
<Button> Dash</Button>
</Link>
</Container>
);
};
const Dashboard = () => {
setPath("/dashboard")
console.log("Dash");
return (
<Container>
<Link to="/home">
<Button> HOME</Button>
</Link>
<h1>Dashboard</h1>
</Container>
);
};
const RedirectPage = () => {
if (!logging) {
return <div></div>;
} else {
return <Login />;
}
};
return (
<Router>
<Route
path="/"
component={() =>
!auth ? <Redirect to="/login" /> : <Redirect to={path} />
}
/>
<Route exact path="/home" component={Home} />
<Route exact path="/dashboard" component={Dashboard} />
<Route exact path="/login" component={RedirectPage} />
</Router>
);
};
export { Routes };
This is my Login component.
import { useState, useContext } from "react";
import {
Button,
Card,
Container,
Typography,
Box,
TextField,
} from "#material-ui/core/";
import { useHistory} from "react-router-dom";
import { signIn } from "../Storage/Auth";
import { UserContext } from "../App";
const Login = () => {
const [mail, setMail] = useState<string>("");
const [password, setPassword] = useState<string>("");
const { user, setUser } = useContext(UserContext);
const handleSignIn = async (m: string, p: string) => {
await signIn(m, p).then((e) => {
console.log("USERID", e, user);
setUser(e);
});
};
const history = useHistory();
const handleEnter = () => {
history.push("/home");
};
const handleOnKey = (e: any) => {
if (e.key === "Enter") {
e.preventDefault();
handleSignIn(mail, password);
handleEnter();
}
};
return (
<Card className="Card" raised={true}>
<Container className="Input">
<Typography className="Sign-in" paragraph={true} variant="inherit">
Sign in
</Typography>
<Box
className="Box"
borderColor="error.main"
border={2}
borderRadius="borderRadius"
>
<Container>
<TextField
fullWidth={true}
placeholder=" email"
value={mail}
onChange={(e) => {
setMail(e.target.value);
}}
onKeyDown={(e) => {
handleOnKey(e);
}}
/>
</Container>
</Box>
</Container>
<Container className="Input">
<Box
className="Box"
borderColor="error.main"
borderRadius="borderRadius"
border={2}
>
<Container>
<TextField
fullWidth={true}
placeholder=" password"
value={password}
onChange={(e) => {
setPassword(e.target.value);
}}
type="password"
onKeyDown={(e) => {
handleOnKey(e);
}}
/>
</Container>
</Box>
<h1> </h1>
<Button
onClick={() => {
handleSignIn(mail, password);
}}
fullWidth={true}
color="primary"
variant="contained"
type="submit"
>
Sign In{" "}
</Button>
<h1> </h1>
<Box className="Sign-in">
<Button size="small"> Register </Button>
</Box>
<h1> </h1>
</Container>
</Card>
);
};
export default Login;
This is the App component:
import { useEffect } from "react";
import { Routes } from "./Routing/Routes";
import "./App.css";
import { Container } from "#material-ui/core/";
import initFirebase from "./Storage/Secret";
import { useState, createContext } from "react";
import { onAuthChange } from "./Storage/Auth";
export const UserContext = createContext<any>(null);
function App() {
const [user, setUser] = useState(null);
const [auth, setAuth] = useState<string | null>("");
const [logging, setLogging] = useState(null)
useEffect(() => {
initFirebase();
}, []);
useEffect(() => {
onAuthChange(setAuth,setLogging);
}, [auth]);
return (
<UserContext.Provider value={{ user, setUser, auth,setAuth,logging }}>
<div className="App">
<Container>
<Routes />
</Container>
</div>
</UserContext.Provider>
);
}
export default App;
Also, here is the auth logic:
import firebase from "firebase/app";
import "firebase/auth";
const auth = () => firebase.auth();
const signIn = async (email, password) => {
await auth()
.signInWithEmailAndPassword(email, password)
.then((userCredential) => {
var user = userCredential.user;
console.log("USER", user);
return user.uid;
})
.catch((error) => {
var errorCode = error.code;
var errorMessage = error.message;
alert(errorCode, errorMessage);
return null;
});
};
const onAuthChange = (setState, setLoading) => {
auth().onAuthStateChanged((u) => {
if (!u) {
console.log(u);
setLoading(true);
} else {
setState(u);
setLoading(false);
}
});
};
const signOut = (setState) => {
auth()
.signOut()
.then(function () {
console.log("LOGGED OUT");
})
.catch(function (error) {
console.log("ERROR LOGGING OUT");
});
setState(null);
};
export { signIn, signOut, onAuthChange }
Finally, the full code is in https://gitlab.com/programandoconro/adminkanjicreator
Any suggestion will be appreciated, thanks.
I would recommend doing the auth check earlier. So something like this so that the routes themselves only get rendered if there is something in auth. I think your example is also missing the Switch statement which often helps.
<Router>
{!auth ? (
<Switch>
<Route exact path="/login" component={RedirectPage} />
</Switch>
) : (
<Switch>
<Route exact path="/home" component={Home} />
<Route exact path="/dashboard" component={Dashboard} />
</Switch>
)}
</Router>
Typically you will want some sort of "loading" or "indeterminant" state to represent neither authenticated nor unauthenticated. You can use this third "state" to hold the UI before committing to rendering one way or the other on anything based upon authentication.
Since your auth logic resolves to a boolean true|false.
const onAuthChange = (setState, setLoading) => {
auth().onAuthStateChanged((u) => {
if (!u) {
console.log(u);
setLoading(true);
} else {
setState(u);
setLoading(false);
}
});
};
You can use the fact that the initial auth state is neither of these. I suggest using null.
const [auth, setAuth] = useState<string | null>(null);
When rendering the Route utilizing the auth state you can augment the logic to return early before deciding to redirect.
<Route
path="/"
render={() => {
if (auth === null) return null;
return <Redirect to={auth ? path : "/login" />;
}}
/>
Note here that I've also switched over to the render prop, the component prop is intended for attaching actual React components. These are treated a little differently. You can read about the route render method differences here.
The full router example:
<Router>
<Switch>
<Route path="/home" component={Home} />
<Route path="/dashboard" component={Dashboard} />
<Route path="/login" component={RedirectPage} />
<Route
path="/"
render={() => {
if (auth === null) return null;
return <Redirect to={auth ? path : "/login" />;
}}
/>
</Switch>
</Router>
Note here that I've also included the Switch component and reordered the routes so the more specific paths are listed before less specific paths. This allows you to remove the unnecessary exact prop from all the routes since the Switch renders routes exclusively (versus inclusively as the Router does).
I finally managed to solve the issue. Now the reload works perfectly and the security was implemented as excepted. This is my final Router:
<Router>
<Route
path="/"
render={() =>
logging ? <Redirect to={"/login"} /> : <Redirect to={path} />
}
/>
<Route exact path="/" render={() => auth && <Home />} />
<Route exact path="/dashboard" render={() => auth && <Dashboard />} />
<Route exact path="/login" component={Login} />
</Router>
This is how the component looks like now.
import {
Route,
BrowserRouter as Router,
Link,
Redirect
} from "react-router-dom";
import { Container, Button } from "#material-ui/core/";
import Login from "./Login";
import { useContext, useState, useEffect } from "react";
import { UserContext } from "../App";
import { signOut } from "../Storage/Auth";
const Routes = () => {
const { auth, setAuth, logging } = useContext(UserContext);
const handleSignOut = () => {
signOut(setAuth);
console.log("Auth", auth);
};
const pathname = window.location.pathname;
const [path, setPath] = useState(pathname);
useEffect(() => {
console.log(path);
path === "/login" && setPath("/");
path !== "/" && path !== "/dashboard" && setPath("/");
}, [auth]);
const Home = () => {
console.log("Home");
return (
<Container>
<h1>Welcome</h1>
<Link to="/">
<Button onClick={handleSignOut}> Log Out</Button>
</Link>
<Link to="/dashboard">
<Button> Dash</Button>
</Link>
</Container>
);
};
const Dashboard = () => {
console.log("Dash");
return (
<Container>
<Link to="/">
<Button> HOME</Button>
</Link>
<h1>Dashboard</h1>
</Container>
);
};
return (
<Router>
<Route
path="/"
render={() =>
logging ? <Redirect to={"/login"} /> : <Redirect to={path} />
}
/>
<Route exact path="/" render={() => auth && <Home />} />
<Route exact path="/dashboard" render={() => auth && <Dashboard />} />
<Route exact path="/login" component={Login} />
</Router>
);
};
export { Routes };
Thanks #Richard and #Drew for their kind support.

react router "# sign inside route"

i using react-router for my project,
in that there's a problem which is for every route "#" sign is added at the start of every router path..
ex": http://localhost:3000/#/login
i want to remove that # sign but i couldn't able solve it my self.
procedure of my routing is
in app.js im checking the user is signed in or not if not signed in then he will redirect into /login page.(for that also it is showing path as http://localhost:3000/#/login)
below is the app.js
import React, { Component, Fragment } from "react";
import { HashRouter, Route, Switch, Redirect } from "react-router-dom";
// import { renderRoutes } from 'react-router-config';
import "./App.scss";
import { connect } from "react-redux";
import { loadUser } from "./actions/authActions";
const loading = () => (
<div className="animated fadeIn pt-3 text-center">Loading....</div>
);
// Containers
const DefaultLayout = React.lazy(() =>
import("./containers/DefaultLayout/DefaultLayout")
);
// Pages
const Login = React.lazy(() => import("./views/Login/Login"));
const Register = React.lazy(() => import("./views/Register/Register"));
const Page404 = React.lazy(() => import("./views/Page404/Page404"));
const Page500 = React.lazy(() => import("./views/Page500/Page500"));
class App extends Component {
componentDidMount() {
this.props.LOADUSER();
}
render() {
return (
<HashRouter>
<React.Suspense fallback={loading()}>
<Switch>
{!this.props.isAuthenicated ? (
<Fragment>
<Redirect from="*" to="/login" />
<Route
exact
path="/login"
name="Login Page"
render={props => <Login {...props} />}
/>
{/* <Route
exact
path="/register"

render={(props) => <Register {...props} />}
/>
<Route

/>
<Route
exact

name="Page 500"
render={(props) => <Page500 {...props} />}
/> */}
</Fragment>
) : (
<Route
name="Home"
path="/"
render={props => <DefaultLayout {...props} />}
/>
)}
</Switch>
</React.Suspense>
</HashRouter>
);
}
}
const mapStateToProps = state => ({
isAuthenicated: state.auth.isAuthenicated,
isLoading: state.auth.isLoading,
error: state.error,
token: state.auth.token
});
const mapDispachToProps = dispach => {
return {
//LOGIN: (newUser) => dispach(login(newUser)),
LOADUSER: () => dispach(loadUser())
};
};
export default connect(mapStateToProps, mapDispachToProps)(App);
else he is signed in then im using a component called DefaultLayout Component I will render it.
it has all the routes for other usages which is using routes from routes.js.
below is the DefaultLayout Component
import React, { Component, Suspense } from "react";

export default connect(mapStateToProps, mapDispachToProps)(DefaultLayout);
example of routes.js also below
const routes =[{
path: "/",
exact: true,
name: "Home",
component: Dashboard
},
{
path: "/user_overview",
name: "Users Overview",
component: Register
}]
for every route it's showing # can anyone help me to resolve that # sign in the route path?
Thank you!
You are using HashRouter this is the purpose of this Router.
Usually one uses it in-order to prevent the server to get those routes.
If you want to use real routes just replace it with BrowserRouter.
Pay attention that your server will need to be able to support those routes.
navigate to some route say /some/page press reload, make sure that your server return your client code.
