The Most Overlooked Feature in Next.js 15 (and a free conference ticket for you)

Published 10 months ago • 2 min read

Hey Reader,

Next.js has a bunch of little features that feel fun at first — but can actually change the way you build.
​
This week’s snack is one of those.

That’s the whole point of Frontend Snacks: giving you small, sharp insights that make a real difference and ones you can actually apply.

Weekly Snack: after function 🍿

Next.js 15 introduces after() — a new API that lets you schedule server-side code to run after the response has been sent to the browser.

So your UI renders instantly, and the heavy lifting happens in the background. 💨

  • The user sees your content instantly.
  • The analytics POST request fires afterward, quietly in the background.

This function is very handy as things like analytics, logging, background tasks should not block your page.

Try it out and let me know what you think by replying to this email!

For the past few months, I’ve been pouring my heart into something special — the Modern Full Stack Next.js Course 💖.

It’s finally taking shape, and I’m so excited to share it with you.

This isn’t just another tutorial series.

It’s a deep, hands-on course that shows you how to actually build production-ready apps with Next.js 15+.

From server components and caching to full-stack architecture and advanced deployment strategies — we’re covering it all.

If you’ve ever felt like you’re jumping from video to video and still not sure how to ship something real… this course is for you.

I’ll be sharing behind-the-scenes progress, sneak peeks, and bonus content exclusively with folks on the waitlist. And of course, you’ll be the first to know when Early Access opens up (with a sweet discount too 😉).
