How to achieve Dynamic routing in React Router 4?

I have a list of articles like this:

<div>
   {
       this.props.articles.map(article => {
            return (
                <ArticleCard key={article._id} article={article} />
            )
        })
    }
</div>

In the ArticleCard component, I'm only showing the title of my article. I want to put a link to it which would create new URL like 'article-title' and show the content.

How to achieve this?

In your ArticleCard, you have to create a Link that will route to your full Article. This link will include the id of the article you are trying to render (ex. articles/${article._id})

By writing the Route path of the component Article as articles/:id, this will allow us to catch that id when Article is rendered (accessible via this.props.match.params.id)

Then, assuming that id is used to fetch the article from some other API, a good place to call that would be the componentDidMount of your Article component.

Here is a small example which may help you out:

import React from 'react'
import {
  BrowserRouter as Router,
  Route,
  Link,
  Switch
} from 'react-router-dom'

const ParamsExample = () => (
  <Router>
    <Switch>
      <Route exact path="/" component={ArticleList} />
      <Route path="/articles/:id" component={Article} />
    </Switch>
  </Router>
)

const article = {
  _id: 1,
  title: 'First Article'
};

const ArticleList = () => (
  <div>
    <ArticleCard key={article._id} article={article} />
  </div>
);

const ArticleCard = ({ article }) => (
  <div>
    <h2>{article.title}</h2>
    <Link to={`/articles/${article._id}`}>SEE MORE</Link>
  </div>
);

class Article extends React.Component {
  componentDidMount() {
    console.log('Fetch API here: ', this.props.match.params.id);
  }

  render() {
    return (
      <div>
        {`Fetching...${this.props.match.params.id}`}
      </div>
    );
  }
}

export default ParamsExample
