How to pass state or data in react-router v6

The react-router is the best library to handle routing in reactjs. With react-router, you pass state or data from one component to another component to use the react-router Link component.

Data pass more quickly in the new version of react-router (v6). For example, you can pass an object's data into one component to another component.

How to pass parameters in react-router-dom Link?

Steps

1. Pass Data
2. Access data

Pass Data

1. First step
2. Second step
3. Third step

First Step

First step import Link Component in react-router-dom

import { Link } from "react-router-dom";

Second Step

In the second step, I create a state with the useState hook in reactjs and pass default data in useState.

const [data, setData] = useState({ id: "1t4",
   title: " How to pass state in react-router-dom",
   tag: ["reactjs", "react-router-dom"]
});   // first example
const [data, setData] = useState(false); second example

Note

You can pass anything in the react-router-dom Link component. I’m pass a object and boolean value for example purpose.

Third step

In the third step, we pass the state as an object from one component to another. in other words, we pass data present to the child.

// you pass state form of object
<Link to="/apple" state={{ data: data }} className="link">
   Apple
</Link>

Note

Pass state as a object in react-router v6. if pass a state as a string, you a face a error.

Access data

Access data in the child component, the react-router (v6), provides a hook for accessing the data.

1. Import hook
2. Access data

Import hook

First, you import a useLocation hook, which component you access the data or state.

import { useLocation } from "react-router-dom";

Access data

Use the useLocation react-router hook to access the state present to the child component.

import React from "react";
import { useLocation } from "react-router-dom";
export default function ApplePage(props) {
const location = useLocation();
console.log(props, " props");
console.log(location, " useLocation Hook");
const data = location.state?.data;
return (
   <div className="page">
     🍎 Page
     <h1> {data ? data.title : "Go to Home"} </h1>
   </div>
);
}

Access data present to child component

Note

Most of the time, new people pass state in link component and access to the props. So it is not working in react-router.

Tips

1. You cant access the state directly to the child component. Instead, you see an undefined hook in the console.
2. You cant access the react-router state in props.
