How to Get Current Route in react-router 2.0.0-rc5
When working with react-router 2.0.0-rc5, you may come across the need to access the current route within your components. In this blog post, we will explore different approaches to obtain the current route and provide the necessary code snippets to accomplish this. Let’s dive in!
Solution 1: Accessing the Injected Property “location”
One way to retrieve the current route is by accessing the injected property called location. This property contains information about the current route, including the pathname. You can access it through this.props.location.pathname. Here’s an example:
var currentLocation = this.props.location.pathname;
Solution 2: Using the “routes” Prop
Another approach is to utilize the routes prop provided by react-router. By accessing the routes prop, you can determine the current route by referencing the lowest-level active Route component. Here’s an example:
const currentRoute = this.props.routes[this.props.routes.length - 1];
Using currentRoute.path, you can retrieve the path of the current route, while currentRoute.component returns the corresponding component.
Solution 3: Utilizing the “history” Object
If you are using the history object, the current route information can be accessed through the pathname property of the location object. Here’s an example:
this.props.location.pathname;
Solution 4: Accessing the Current Route via Context
Starting from version 3.0.0, you can also retrieve the current route by calling this.context.router.location.pathname. Here’s an example:
var NavLink = React.createClass({
contextTypes: {
router: React.PropTypes.object
},
render() {
return (
<Link {...this.props}></Link>
);
}
});
Solution 5: Retrieving the Current Route with Context
For users facing the same issue in 2017, you can access the current route by adding the necessary contextTypes and using this.context.location.pathname. Here’s an example:
NavBar.contextTypes = {
router: React.PropTypes.object,
location: React.PropTypes.object
}
componentDidMount () {
console.log(this.context.location.pathname);
}
Solution 6: Using Window Location
Another method involves accessing the current route using window.location.pathname. Here’s an example:
window.location.pathname;
Solution 7: Utilizing the “isActive” Prop
If you want to check if a specific route is currently active, you can use the isActive prop provided by react-router. The following example demonstrates how to verify if the “/login” route is active and redirect to the home (“/”) route if necessary:
const { router } = this.context;
if (router.isActive('/login')) {
router.push('/');
}
Conclusion
In this blog post, we explored several methods to obtain the current route in react-router 2.0.0-rc5. Depending on your specific requirements and project setup, you can choose the most suitable solution for accessing the current route information. Implementing any of the provided solutions will allow you to effectively work with and manipulate routes in your react-router application. Happy coding!
