React Router with optional path parameter

React Router with Optional Path Parameter: A Complete Guide

Are you trying to declare a path with an optional path parameter in your React Router? 🤔 If so, you're in the right place! In this blog post, we'll address the common issues faced when working with optional path parameters and provide easy solutions to overcome them. Let's dive in! 💪

The Problem: Why is the Route Without the Parameter Not Found?

Many developers face the issue of the route without the parameter not being found when working with optional path parameters. This occurs because React Router treats the path segment with the parameter as a required segment, resulting in the non-parameterized route not being matched.

So, how can we declare it in one route and ensure that both options work seamlessly? 🤔

The Solution: Declaring Optional Path Parameters

To declare a path with an optional path parameter in React Router, we can follow a simple approach. Instead of using the traditional parameter syntax, we can use a custom query parameter syntax.

First, let's take a look at the simplified example in the context of your question:

<Router history={history}>
  <Route path="/path" component={IndexPage}>
    <Route path="to/page" component={MyPage} />
    <Route path="to/page(/:pathParam)" component={MyPage} />
  </Route>
</Router>

In the second Route component, notice the use of parentheses around :pathParam. This tells React Router that the parameter is optional. Now, both routes with or without the parameter will be matched correctly. 🎉

Let's break it down:

• /to/page: Matches the route without the parameter

• /to/page/pathParam: Matches the route with the parameter, providing the necessary data to MyPage

Now that we've solved the problem at hand, you might be wondering if this syntax exists in the official React Router documentation. Unfortunately, it doesn't. However, this custom approach has been widely adopted and tested by the community, proving its effectiveness.
