I'm looking for a way to modify the page title when React-Router v4+ changes locations. I used to listen for a location change action in Redux and check that route against a metaData
object.
When using React-Router v4+, there's no fixed routes list. In fact, various components around the site could use Route
with the same path string. That means old method I used won't work anymore.
Is there a way I can update the page title by calling actions when certain major routes are changed or is there a better a better method to update the site's metadata?

Same as Thierry Prost's custom hook, but modified for TypeScript:
import { useEffect } from "react";
const useTitle = (title:string) => {
useEffect(() => {
const prevTitle = document.title;
title && (document.title = title);
return () => {document.title = prevTitle};
}, [title]);
};
export default useTitle;

I have a short and simple solution using react hook
with or without react router
.
I just created a file named 'useDocumentTitle.tsx' :
import React, { useEffect } from 'react';
const useDocumentTitle = (title: string, default_title: string | undefined
= 'My default title') => {
useEffect(() => {
document.title = title + ' | ' + default_title;
return () => {
document.title = default_title;
};
}, []);
};
export default useDocumentTitle;
The useEffect
sets the document title on page load, while the return function
reset the title back to default in case the next component doesn't use the useDocumentTitle hook
.
If I want to dynamically change the document title based on change in parameter, I will add the title
in the dependency array
of useEffect
.
useEffect(() => {
document.title = title + ' | ' + default_title;
return () => {
document.title = default_title;
};
}, [title]);
In my components, I just add :
useDocumentTitle('Customer')
If I want to change the title to different default title on leaving page :
useDocumentTitle('Customer', 'My Company Info')

If you just want to show the title of the component, the code example below should also work:
useEffect(() =>
{
document.title = "My page title";
}, []);

I asked question "how to set title correctly" on official github repo of "react router dom". They answered "This isn't something the Router does. You're looking for a library like react-helmet.".
If you want to change title in react router tutorial, you just need to
npm install react-helmet
after that go to your react router dom page (eg contact.jsx) and add such code
import { Helmet } from "react-helmet";
export default function Contact() {
const { contact } = useLoaderData();
return (
<div id="contact">
<Helmet>
<title>{ contact.first??'Новый контакт' }</title>
</Helmet>
And it works correctly in march 2023.

I am answering this because I feel you could go an extra step to avoid repetitions within your components and you could just get the title updated from one place (the router's module).
I usually declare my routes as an array but you could change your implementation depending on your style. so basically something like this ==>
import {useLocation} from "react-router-dom";
const allRoutes = [
{
path: "/talkers",
component: <Talkers />,
type: "welcome",
exact: true,
},
{
path: "/signup",
component: <SignupPage />,
type: "onboarding",
exact: true,
},
]
const appRouter = () => {
const theLocation = useLocation();
const currentLocation = theLocation.pathname.split("/")[1];
React.useEffect(() => {
document.title = `<Website Name> |
${currentLocation[0].toUpperCase()}${currentLocation.slice(1,)}`
}, [currentLocation])
return (
<Switch>
{allRoutes.map((route, index) =>
<Route key={route.key} path={route.path} exact={route.exact} />}
</Switch>
)
}
Another approach would be declaring the title already in each of the allRoutes
object and having something like @Denis Skiba's solution here.

Picking up from the excellent answer of phen0menon, why not extend Route
instead of React.Component
?
import React, { useEffect } from 'react';
import { Route } from 'react-router-dom';
import PropTypes from 'prop-types';
export const Page = ({ title, ...rest }) => {
useEffect(() => {
document.title = title;
}, [title]);
return <Route {...rest} />;
};
This will remove overhead code as seen below:
// old:
<Route
exact
path="/"
render={props => (
<Page {...props} component={Index} title="Index Page" />
)}
/>
// improvement:
<Page
exact
path="/"
component={Index}
title="Index Page"
/>
Update: another way to do it is with a custom hook:
import { useEffect } from 'react';
/** Hook for changing title */
export const useTitle = title => {
useEffect(() => {
const oldTitle = document.title;
title && (document.title = title);
// following line is optional, but will reset title when component unmounts
return () => document.title = oldTitle;
}, [title]);
};

I built a bit on Thierry Prosts solution and ended up with the following:
UPDATE January 2020: I've now updated my component to be in Typescript as well:
UPDATE August 2021: I've added my private route in TypeScript
import React, { FunctionComponent, useEffect } from 'react';
import { Route, RouteProps } from 'react-router-dom';
interface IPageProps extends RouteProps {
title: string;
}
const Page: FunctionComponent<IPageProps> = props => {
useEffect(() => {
document.title = "Website name | " + props.title;
});
const { title, ...rest } = props;
return <Route {...rest} />;
};
export default Page;
UPDATE: My Page.jsx component is now a functional component and with useEffect hook:
import React, { useEffect } from 'react';
import { Route } from 'react-router-dom';
const Page = (props) => {
useEffect(() => {
document.title = "Website name | " + props.title;
});
const { title, ...rest } = props;
return <Route {...rest} />;
}
export default Page;
Below you can find my initial solution:
// Page.jsx
import React from 'react';
import { Route } from 'react-router-dom';
class Page extends Route {
componentDidMount() {
document.title = "Website name | " + this.props.title;
}
componentDidUpdate() {
document.title = "Website name | " + this.props.title;
}
render() {
const { title, ...rest } = this.props;
return <Route {...rest} />;
}
}
export default Page;
And my Router implementation looked like this:
// App.js / Index.js
<Router>
<App>
<Switch>
<Page path="/" component={Index} title="Index" />
<PrivateRoute path="/secure" component={SecurePage} title="Secure" />
</Switch>
</App>
</Router>
Private route setup:
// PrivateRoute
function PrivateRoute({ component: Component, ...rest }) {
return (
<Page
{...rest}
render={props =>
isAuthenticated ? (
<Component {...props} />
) : (
<Redirect
to={{
pathname: "/",
state: { from: props.location }
}}
/>
)
}
/>
);
}
Private Route in TypeScript:
export const PrivateRoute = ({ Component, ...rest }: IRouteProps): JSX.Element => {
return (
<Page
{...rest}
render={(props) =>
userIsAuthenticated ? (
<Component {...props} />
) : (
<Redirect
to={{
pathname: Paths.login,
state: { from: props.location },
}}
/>
)
}
/>
);
};
This enabled me to have both public areas update with a new title and private areas also update.

<Route />
components have render property. So you can modify the page title when location changes by declaring your routes like that:
<Route
exact
path="/"
render={props => (
<Page {...props} component={Index} title="Index Page" />
)}
/>
<Route
path="/about"
render={props => (
<Page {...props} component={About} title="About Page" />
)}
/>
In Page
component you can set the route title:
import React from "react"
/*
* Component which serves the purpose of a "root route component".
*/
class Page extends React.Component {
/**
* Here, we define a react lifecycle method that gets executed each time
* our component is mounted to the DOM, which is exactly what we want in this case
*/
componentDidMount() {
document.title = this.props.title
}
/**
* Here, we use a component prop to render
* a component, as specified in route configuration
*/
render() {
const PageComponent = this.props.component
return (
<PageComponent />
)
}
}
export default Page
Update 1 Aug 2019. This only works with react-router >= 4.x. Thanks to @supremebeing7
Updated answer using React Hooks:
You can specify the title of any route using the component below, which is built by using useEffect
.
import { useEffect } from "react";
const Page = (props) => {
useEffect(() => {
document.title = props.title || "";
}, [props.title]);
return props.children;
};
export default Page;
And then use Page
in the render
prop of a route:
<Route
path="/about"
render={(props) => (
<Page title="Index">
<Index {...props} />
</Page>
)}
/>
<Route
path="/profile"
render={(props) => (
<Page title="Profile">
<Profile {...props} />
</Page>
)}
/>

Dan Abramov (creator of Redux and current member of the React team) created a component for setting the title which works with new versions of React Router also. It's super easy to use and you can read about it here:
https://github.com/gaearon/react-document-title
For instance:
<DocumentTitle title='My Web App'>

Please use react-helmet. I wanted to give the Typescript example:
import { Helmet } from 'react-helmet';
const Component1Title = 'All possible elements of the <head> can be changed using Helmet!';
const Component1Description = 'No only title, description etc. too!';
class Component1 extends React.Component<Component1Props, Component1State> {
render () {
return (
<>
<Helmet>
<title>{ Component1Title }</title>
<meta name="description" content={Component1Description} />
</Helmet>
...
</>
)
}
}

You also can go with the render
method
const routes = [
{
path: "/main",
component: MainPage,
title: "Main Page",
exact: true
},
{
path: "/about",
component: AboutPage,
title: "About Page"
},
{
path: "/titlessPage",
component: TitlessPage
}
];
const Routes = props => {
return routes.map((route, idx) => {
const { path, exact, component, title } = route;
return (
<Route
path={path}
exact={exact}
render={() => {
document.title = title ? title : "Unknown title";
console.log(document.title);
return route.component;
}}
/>
);
});
};
the example at codesandbox (Open result in a new window for see title)

Using a functional component on your main routing page, you can have the title change on each route change with useEffect.
For example,
const Routes = () => {
useEffect(() => {
let title = history.location.pathname
document.title = title;
});
return (
<Switch>
<Route path='/a' />
<Route path='/b' />
<Route path='/c' />
</Switch>
);
}

Here is my solution which is almost the same as simply setting document.title
but using useEffect
/**
* Update the document title with provided string
* @param titleOrFn can be a String or a function.
* @param deps? if provided, the title will be updated when one of these values changes
*/
function useTitle(titleOrFn, ...deps) {
useEffect(
() => {
document.title = isFunction(titleOrFn) ? titleOrFn() : titleOrFn;
},
[...deps]
);
}
This has the advantage to only rerender if your provided deps
change.
Never rerender:
const Home = () => {
useTitle('Home');
return (
<div>
<h1>Home</h1>
<p>This is the Home Page</p>
</div>
);
}
Rerender only if my userId
changes:
const UserProfile = ({ match }) => {
const userId = match.params.userId;
useTitle(() => `Profile of ${userId}`, [userId]);
return (
<div>
<h1>User page</h1>
<p>
This is the user page of user <span>{userId}</span>
</p>
</div>
);
};
// ... in route definitions
<Route path="/user/:userId" component={UserProfile} />
// ...
CodePen here but cannot update frame title
If you inspect the <head>
of the frame you can see the change:

With a little help from Helmet:
import React from 'react'
import Helmet from 'react-helmet'
import { Route, BrowserRouter, Switch } from 'react-router-dom'
function RouteWithTitle({ title, ...props }) {
return (
<>
<Helmet>
<title>{title}</title>
</Helmet>
<Route {...props} />
</>
)
}
export default function Routing() {
return (
<BrowserRouter>
<Switch>
<RouteWithTitle title="Hello world" exact={true} path="/" component={Home} />
</Switch>
</BrowserRouter>
)
}

In your componentDidMount()
method do this for every page
componentDidMount() {
document.title = 'Your page title here';
}
This will change your page title, do the above mentioned for every route.
Also if it is more then just the title part, check react-helmet It is a very neat library for this, and handles some nice edge cases as well.
