Using redirects in React Router
If you are a developer working on complex web applications, you probably understand the importance of routing. Routing is one of the key parts that make up the navigation system of an application. ReactJs developers tend to use react-router-dom
the package to create routes for their applications.
After submitting a form (or any other user action), sometimes the application needs to navigate to a different URL. In this article, we will look at how to handle redirects in React.
Hooks can extend the base functionality of functional components. React developers can use built-in hooks such as useReducer()
, useState()
, useEffect()
or create their own custom versions.
useHistory()
Returns a history
instance containing the component's current location (URL). Handling redirects is not the primary purpose of this hook. However, new versions of React Router (5 and above) allow you to use this hook to redirect users in an efficient and readable way.
Let's look at this example:
import { useHistory } from "react-router-dom"
function SampleComponent() {
let history = useHistory()
function handleClick() {
history.push("/somepage")
}
return (
<span onClick={() => handleClick()}>
Go home
</span>
)
}
In this example, we react-router-dom
import useHistory
the hook from the package. We then define a simple functional component that returns a single <span>
element with an click
event handler for the event.
We also create a history
variable to store useHistory()
the instance returned by the hook.
In the body of the event handler function, we use .push()
the method and pass a string as a parameter. The parameter of this method will be added to the end of the current URL. So, if our application localhost:3000
is running on port , and we have to handle click
the event, our URL will change to localhost:3000/somepage
.
Another way to navigate to a different URL after an action (submitting a form, clicking a button, or any other user action) is to use a custom <Redirect>
component. You can "react-router-dom"
import it from the library.
You can control when the redirect occurs by conditionally rendering the redirect based on a state value. Let's look at this example:
import React from "react"
import { Redirect } from "react-router-dom"
class MyComponent extends React.Component {
constructor(props){
super(props)
this.state = {
condition: false
}
}
handleClick () {
axios.post(/*URL*/)
.then(() => this.setState({ condition: true }));
}
render () {
const { condition } = this.state;
if (condition) {
return <Redirect to='/somePage'/>;
}
return <button onClick={() => this.handleClick()}>Redirect</button>;
}
Our state has a condition
property which is set to false
. Because of this boolean value, <Redirect>
the component does not render and the user's URL does not change.
By clicking a single button, the user can trigger an event handler condition
that sets the property to true
. In this case, if
the condition of the statement will be met and the render function will return <Redirect>
a component that takes the user to the specified relative path.
In this case, if our application's homepage is located at localhost:3000
, and our <Redirect>
component has a property with a value '/somePage'
of to
, the user will be redirected to the following location: localhost:3000/somePage
.
Using useHistory()
the hook is not the only way to access the user's current location. Developers can achieve the same functionality in both types of components by reading the property props
of the object .history
If you want a redirect to occur after clicking a button, you must set up a onClick
event handler that uses .push("")
the method to provide a relative path to where the user should be redirected. Here is an example:
<button onClick={this.props.history.push('/somePage')}>Redirect to some page </button>
If their current location is localhost:3000
on the Home Page, clicking this button will take the user to localhost:3000/somePage
the URL.
