Call React component with dynamic URL parameters

Question

For now, I am rendering a React Component with a static URL.

I would like to pass it a dynamic URL.

For instance, rather than calling it like this:

https://www.example.com

I would like to call it like this:

https://www.example.com/?name=John

And I would like this to update its this.props.name or this.state.name components.

Can I do that?

What should I use for this purpose? react-router?

Or can this only be done from the backend?

Yes, you can use react-router; It can be used from the front or back end See github.com/reactjs/react-router — Ruan Mendes

You do not need react-router. Following would parse your url:

    let url_parameter = {};
    const currLocation = window.location.href,
        parArr = currLocation.split("?")[1].split("&");
    for (let i = 0; i < parArr.length; i++) {
        const parr = parArr[i].split("=");
        url_parameter[parr[0]] = parr[1];
    }

However, if you use react-router you might want to go the the resource. Than the link would look like this:

http://www.example.com/john

In this case react allows to get the resource in the this.props.params: Here how to specify the route:

 <Route path="/:name" component={Name}>

Here how to access the name in the component 'Name':

....
render() {
   const {name} = this.props.params;
   ...
}

I hope this helps.
