React Router is a popular library for managing routing in React applications. With React Router, we can easily navigate between different pages or components in the application based on the URL. One common use case in web applications is passing data between pages or components. In this article, we will discuss how to pass data in React Router history.push method with code examples.
React Router provides a few ways to pass data between pages or components. The most common ways are query parameters, state, and props. In this article, we will focus on passing data through query parameters and state using history.push method.
Passing Data via Query Parameters
Query parameters are a way to pass data in the URL. Query parameters are a string of key-value pairs separated by an ampersand (&) and preceded by a question mark (?). We can access the query parameters in the target component using the location prop.
Here's an example of passing data via query parameters using history.push method:
import { useHistory } from 'react-router-dom';
const MyComponent = () => {
const history = useHistory();
const handleClick = () => {
history.push('/target-component?foo=bar&baz=qux');
};
return (
<button onClick={handleClick}>Go to Target Component</button>
);
};
In this example, we are using the useHistory hook from react-router-dom to get the history object. We are passing the target path and query parameters as a string in the argument of the history.push method.
To access the query parameters in the target component, we can use the location prop from react-router-dom and parse the query string using the query-string library.
import { useLocation } from 'react-router-dom';
import queryString from 'query-string';
const TargetComponent = () => {
const location = useLocation();
const queryParams = queryString.parse(location.search);
return (
<div>
<p>Foo: {queryParams.foo}</p>
<p>Baz: {queryParams.baz}</p>
</div>
);
};
In this example, we are using the useLocation hook from react-router-dom to get the location object. We are parsing the query string using the queryString.parse method from the query-string library. We can then access the query parameters as key-value pairs from the queryParams object.
Passing Data via State
Another way to pass data between pages or components is via state. State is an object that can be passed as an argument in the history.push method. We can access the state object in the target component using the location prop.
Here's an example of passing data via state using history.push method:
import { useHistory } from 'react-router-dom';
const MyComponent = () => {
const history = useHistory();
const handleClick = () => {
history.push({
pathname: '/target-component',
state: { foo: 'bar', baz: 'qux' }
});
};
return (
<button onClick={handleClick}>Go to Target Component</button>
);
};
In this example, we are passing the target path as a key-value pair object. We are also passing the state object containing the data as another key-value pair object in the argument of the history.push method.
To access the state object in the target component, we can use the location prop from react-router-dom.
import { useLocation } from 'react-router-dom';
const TargetComponent = () => {
const location = useLocation();
return (
<div>
<p>Foo: {location.state.foo}</p>
<p>Baz: {location.state.baz}</p>
</div>
);
};
In this example, we are using the useLocation hook from react-router-dom to get the location object. We can then access the state object as key-value pairs from the location.state object.
Conclusion
In this article, we discussed two ways to pass data in React Router history.push method: query parameters and state. Query parameters are a way to pass data in the URL, and state is an object that can be passed as an argument in the history.push method. We also provided examples and code snippets for passing data through query parameters and state. With these methods, passing data between pages or components in a React application becomes easier.

Popular questions
Certainly! Here are five potential questions and their answers related to passing data in React Router's history.push() method using code examples.
Q1. What are some common ways to pass data between pages or components in React Router?
A1. React Router provides a few methods to pass data between pages or components, including query parameters, state, and props. The query parameters are a way of passing a string of key-value pairs in the URL. State allows for an object to be passed as an argument in the history.push() method. Props are also commonly used to pass data between components.
Q2. What is an example of passing data via query parameters using history.push() in React Router?
A2. Here's an example of passing data via query parameters using the history.push() method with React Router:
import { useHistory } from 'react-router-dom';
const MyComponent = () => {
const history = useHistory();
const handleClick = () => {
history.push('/target-component?foo=bar&baz=qux');
};
return (
<button onClick={handleClick}>Go to Target Component</button>
);
};
In this example, we're using the useHistory() Hook from react-router-dom to get the history object, and then we're passing the target path and query parameters, represented as a string, as an argument in the push() method.
Q3. How do you access query parameters in the target component using React Router?
A3. To access query parameters in the target component using React Router, you can use the location prop provided by react-router-dom and parse the query string using the query-string library. You can then access the query parameters from the resulting object.
import { useLocation } from 'react-router-dom';
import queryString from 'query-string';
const TargetComponent = () => {
const location = useLocation();
const queryParams = queryString.parse(location.search);
return (
<div>
<p>Foo: {queryParams.foo}</p>
<p>Baz: {queryParams.baz}</p>
</div>
);
};
In this example, we used the useLocation() Hook here to get the location object, then used queryString.parse() method to extract the query parameters by calling location.search.
Q4. How do you pass data via state using the history.push() method in React Router?
A4. You can pass data via state by including an object containing the data as an argument in the history.push() method, like so:
import { useHistory } from 'react-router-dom';
const MyComponent = () => {
const history = useHistory();
const handleClick = () => {
history.push({
pathname: '/target-component',
state: { foo: 'bar', baz: 'qux' }
});
};
return (
<button onClick={handleClick}>Go to Target Component</button>
);
};
In this example, we're passing an object containing the data we want to pass as the state property in the argument we pass to the push() method of the history object.
Q5. How do you access state in the target component using React Router?
A5. To access the state in the target component using React Router, you can use the location prop provided by react-router-dom.
import { useLocation } from 'react-router-dom';
const TargetComponent = () => {
const location = useLocation();
return (
<div>
<p>Foo: {location.state.foo}</p>
<p>Baz: {location.state.baz}</p>
</div>
);
};
In this example, we're using the useLocation() Hook to get the location object, then access the state object as key-value pairs from the location.state object.
