In this post, I'll show you how to create a simple component to add a dynamic title behavior on your web app.
Here you have a repo with an applicable example: GitHub Repo
Resume
- Add the
react-helmet
dependency. - Write the dynamic component for the title.
- Add the dynamic component to your router or your pages.
Add the react-helmet
dependency.
If you're using yarn
$ yarn add react-helmet
If you're using npm
$ npm i react-helmet
Write the dynamic component for the title.
You can write an independent component for this example, like this:
// TitleComponent.jsx
import React from 'react';
import Helmet from 'react-helmet';
const TitleComponent = ({ title }) => {
var defaultTitle = '⚛️ app';
return (
<Helmet>
<title>{title ? title : defaultTitle}</title>
</Helmet>
);
};
export { TitleComponent };
In this example, we just wrote an independent component that could receive a title and, if you don't send a prop
as title, the title will be the default title.
Add the dynamic component to your routes.
We have multiple approaches to add this component to your app, it depends mostly on your decisions on routing (if you're using Gatsby or Next.js you can ovoid configure a router, but if you're using create-react-app or a react boiler template you can add this to your router.
Adding this component to your routes (Using router):
// routes.js
import React from 'react';
import { Route } from 'react-router';
import { TitleComponent } from './TitleComponent.jsx';
// withTitle function
const withTitle = ({ component: Component, title }) => {
return class Title extends Component {
render() {
return (
<React.Fragment>
<TitleComponent title={title} />
<Component {...this.props} />
</React.Fragment>
);
}
};
};
// Example pages
const Index = () => <h1>This is the IndexComponent!</h1>;
const Persons = () => <h1>This is the PersonsComponent!</h1>;
const Dogs = () => <h1>This is the DogsComponent!</h1>;
const Food = () => <h1>This is the FoodComponent!</h1>;
// Adding title
const IndexComponent = withTitle({ component: Index, title: 'Index' });
const PersonsComponent = withTitle({ component: Persons, title: '🧠 Persons' });
const DogsComponent = withTitle({ component: Dogs, title: '🐶 Dogs' });
const FoodComponent = withTitle({ component: Food, title: '🌮 Food' });
// Your router
export default (
<Route>
<Route path="/" component={IndexComponent} />
<Route path="/persons" component={PersonsComponent} />
<Route path="/dogs" component={DogsComponent} />
<Route path="/food" component={FoodComponent} />
</Route>
);
Adding this component to your pages (Using Next.js, Gatsby, After.js):
Using withTitle
function:
// pages/pageOne.jsx
import React from 'react';
import { TitleComponent } from './TitleComponent.jsx';
// withTitle function
const withTitle = ({ component: Component, title }) => {
return class Title extends Component {
render() {
return (
<React.Fragment>
<TitleComponent title={title} />
<Component {...this.props} />
</React.Fragment>
);
}
};
};
const PageOne = () => (
<React.Fragment>
<h1> Page 1 </h1>
// Some content...
</React.Fragment>
);
export default withTitle({ component: PageOne, title: 'Page One!' });
Adding directly the <TitleComponent />
to your page:
// pages/pageOne.jsx
import React from 'react';
import { TitleComponent } from './TitleComponent.jsx';
const PageOne = () => (
<React.Fragment>
<TitleComponent title="Page One!" />
<h1> Page 1 </h1>
// Some content...
</React.Fragment>
);
export default PageOne;

And that's it. Thanks for reading and happy coding!

For those using React Hooks, here is the
withTitle
function:I think you have mistakenly used
HelmetComponent
instead ofTitleComponent
.Great observation, fixed!
if you are struggling with integrating helmet title to your project , run this command npm i helmet
once installed
simply copy and paste into a new file called TitleComponent.js in the src folder
// TitleComponent.js
import React from 'react';
import Helmet from 'react-helmet';
const TitleComponent = ({ title }) => {
var defaultTitle = '⚛️ app';
return (
{title ? title : defaultTitle}
);
};
export { TitleComponent };
and in your app.js inside return(
//paste this !!
)
// lets assume that you have a contact page
import {TitleComponent } from './TitleComponent';
paste this into contact page inside a dev
tag
Its really confused me from the beginning, let me know if you need any help with this
Happy Codding :)
Thanks LuisPa for the post.
May I ask how
HelmetComponent
is implemented? I can't seem to find the source in the article 🙏Sure man! Here you have a repo with an aplicable example: GitHub Repo
✨🌠💫🌟⭐
I have is problem
TypeError: Cannot call a class as a function
my code
thepracticaldev.s3.amazonaws.com/i...
Hi! Please put here the code from the
withTitle()
method, please.You can see the example repo:
github.com/LuisPaGarcia/react-dyna...
Here my code
thepracticaldev.s3.amazonaws.com/i...

I only did change extends Component to extens React.Component at the TitleComponent
