React Router is all about mapping URL paths to React components. However, sometimes you desire React Router to return a component when none of the Routesouth match.

The most common use instance for this is showing a 404 page. Regardless of if you lot want to show off your artistic side or not, having a 404 page in identify is a small thing that volition go a long way for the UX of your site. Luckily, this is pretty unproblematic to practice with React Router's Routes component.

Routes is the powerhouse of React Router. Whenever the app's location changes, any Routes component will look through all its children Road elements to observe the best friction match to render.

            
              <              Routes              >            
            
                                          <              Route                                          path              =              "              /              "                                          chemical element              =              {              <              Domicile                                          />              }                                          />            
            
                                          <              Route                                          path              =              "              /about              "                                          chemical element              =              {              <              Nearly                                          />              }                                          />            
            
                                          <              Route                                          path              =              "              /settings              "                                          element              =              {              <              Settings                                          />              }                                          />            
            
              </              Routes              >

Unlike previous versions of React Router, the social club of the children Routes doesn't affair since Routes is intelligent – significant an algorithm at present determines which is the all-time Route to return. This makes rendering a 404 component pretty simple.

All you have to practice is render a Route with a path of * , and React Router volition make sure to simply return the element if none of the other Roads match.

Before you leave

I know, "some other newsletter pitch" - just hear me out. Near JavaScript newsletters are terrible. When'due south the last time you really looked forward to getting one? Even worse, when's the concluding time you actually read one rather than just skim it?

We wanted to change that, which is why we created Bytes. The goal was to create a JavaScript newsletter that was both educational and entertaining. 221,981 subscribers and an almost 50% weekly open charge per unit afterward, it looks similar nosotros did information technology.

Delivered to 221,981 developers every Monday

    This is the offset always newsletter that I open a music playlist for and maximize my browser window just to read it in peace. Kudos to @uidotdev for great weekly content.

    The Bytes newsletter is a work of fine art! It's the only dev newsletter I'yard subscribed as well. They somehow accept semi boring stuff and infuse it with only the correct corporeality of one-act to make you lot chuckle.

    I subscribe to A LOT of dev (especially JS/TS/Node) newsletters and Bytes by @uidotdev is e'er such a welcomed, enjoyable modify of stride to most (funny, lighthearted, etc) merely even so comprehensive/useful.

    I know I've said information technology before, but @tylermcginnis doesn't miss with the Bytes e-mail. If you lot're a developer, you really need to subscribe

    Can I only say that I giggle every time I get the @uidotdev electronic mail each week? You should definitely subscribe.

    Avatar for @thefinnomenon

    Every JavaScript programmer should be subscribed to the newsletter from @uidotdev. Not merely do they manage to succinctly cover the hot news in the JavaScript world for the week but it they manage to add together a refreshing sense of humour to it all.
