This post assumes you're using React Router v6. If not, find your version below.What I love about React Router is its dedication to declarative, "React like" code. The whole goal of the redesign from React Router v3 to v4+ was to align React Router's vision with React's. Fundamentally, what this means is that the same mental model that applies to React should also apply to React Router.
If you broke React down into three core principles, you'd get component composition, declarative UI, and state management - specifically, that user events trigger state changes, which then causes a re-render. Because React Router's vision is aligned with React's, programmatically navigating with React Router should, by definition, align with those three core concepts. The reason I'm emphasizing this is because your initial reaction to what's coming next might be negative.
Declarative Navigation with <Navigate />
The primary way you programmatically navigate using React Router is by using a <Navigate />
component. Now I know what you're thinking - how could navigating with a component be a good idea? But let's first look at an example, and then we'll walk through why this isn't as crazy as it may first appear.
The typical use case for routing programmatically is routing on some sort of user event that isn't a Link
click. So in our example, let's Navigate
the user to /dashboard
once they've registered for our app.
import { Navigate } from "react-router-dom";function Register() {const [toDashboard, setToDashboard] = React.useState(false);if (toDashboard === true) {return <Navigate to="/dashboard" />;}return (<div><h1>Register</h1><Form afterSubmit={() => toDashboard(true)} /></div>);}
After reading that, there's at least a small chance that you hate it. Instead of using an imperative API, something like navigate('/dashboard')
, we're using a declarative Navigate
component. Again, the reason for this is because it aligns exactly with the principles of React itself.
<Navigate />
is composable, declarative, and follows the flow of React – namely a user event triggers a state change which causes a re-render.
What are the downsides to this approach? The most often heard criticism is that you need to create a new property on the component's state in order to know when to render the Navigate
component. That's valid, but again, that's pretty much the whole point of React - state changes update the UI.
"It's more typing", yes. Naturally, by explicitly defining and modifying your state, you have to type more. However, I'd argue that explicit state leading to a declarative API is better than implicit state handled by an imperative API.
**Steps off high horse**
Let's take a look at the other approach now.
Imperative Navigation with useNavigate
React Router also comes with a useNavigate
Hook which gets you access to navigate
- React Router's imperative API for programmatically navigating.
Going back to our example from earlier, if we wanted to use the imperative navigate
method, it would look like this.
import { useNavigate } from 'react-router-domfunction Register () {const navigate = useNavigate()return (<div><h1>Register</h1><Form afterSubmit={() => navigate('/dashboard')} /></div>)}
Easy peasy. Worse, IMO. But, easy peasy.
There are two ways to programmatically navigate with React Router - <Navigate />
and navigate()
.
You can get access to Navigate
by importing it from the react-router-dom
package and you can get access to navigate
by using the custom useNavigate
Hook.
Which you use is mostly up to you and your specific use case, though I try to favor Navigate
as it's more declarative.
