React Router uses a declarative, component-based approach to routing. What that means is when you want to create a new route, you render a Route
component. Route
allows you to map URL paths to different React components. For example, say we wanted to render a Dashboard
component whenever a user navigates to the /dashboard
path. To do that, we'd render a Route
that looked like this.
<Route path="/dashboard" element={<Dashboard />} />
Now, what if we also wanted to pass the Dashboard
component a prop?
In previous versions of React Router (v4), this was non-trivial since React Router was in charge of creating the React element. To get around this, you'd have to use Route
s render
prop.
// React Router v4<Routepath="/dashboard"render={(props) => <Dashboard {...props} authed={true} />}/>
However, with React Router v6, since you're in charge of creating the element, you just pass a prop to the component as you normally would.
<Route path="/dashboard" element={<Dashboard authed={true} />} />

I know, "another newsletter pitch" - but hear me out. Most JavaScript newsletters are terrible. When's the last time you actually looked forward to getting one? Even worse, when's the last 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. 101,879 subscribers and an almost 50% weekly open rate later, it looks like we did it.
Delivered to 101,879 developers every Monday

This is the first ever 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 art! It's the only dev newsletter I'm subscribed too. They somehow take semi boring stuff and infuse it with just the right amount of comedy to make you chuckle.

Bytes has been my favorite newsletter since its inception. It's my favorite thing I look forward to on Mondays. Goes great with a hot cup of coffee!

I subscribe to A LOT of dev (especially JS/TS/Node) newsletters and Bytes by @uidotdev is always such a welcomed, enjoyable change of pace to most (funny, lighthearted, etc) but still comprehensive/useful.

I know I've said it before, but @tylermcginnis doesn't miss with the Bytes email. If you're a developer, you really need to subscribe

Can I just say that I giggle every time I get the @uidotdev email each week? You should definitely subscribe.

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