Breadcrumbs are typically small pieces of text that show the current location within a website.
They can be helpful in orienting users, especially when navigating through websites having several pages.
Rather, they should be used in addition to other navigation elements such as a menu or search bar.
But before starting, you have tocreate a React app.
The library provides acomponent that can be used to create breadcrumbs.
For that, it’s possible for you to use theclassNameprop of the component.
The react-router-dom library’suseLocationhook gives you access to the location object, which has information about the current URL path.
The component’s className prop adds a CSS class to the breadcrumbs.
The className prop takes a string or an array of strings.
If it’s a string, it’ll add the string as a single class to the element.
If it’s an array of strings, each string in the array will add as a separate class.
ThestartsWithmethod checks if the current pathname starts with “/products”.
This library automatically generates breadcrumbs based on the routes defined in your React system.
Each breadcrumb object contains information about the route, such as the name, path, and params.
Now, it’s possible for you to render your breadcrumbs to the screen.

An array of route objects is created.
Each route object contains a path and a breadcrumb property.
