Intro to Analytics Dashboard

Welcome to the Pulse app, a dashboard for your analytics.

In this module, you’re going to take a real-world analytics dashboard and turn it into a blazing fast, modern, production-grade app using the latest from React 19 and Next.js 15.

This isn’t just about tinkering. You’re going to ship something that looks great, feels instant, and follows best practices trusted by performance-minded teams.

Let's review what you'll learn by the end of this module:

🚀 What You’ll Learn by the End of This Module

Here's everything you'll learn:

• Stream React Server Components (RSCs) for fast, chunked UI delivery.
• Avoid layout shifts with smart Skeleton UIs and Suspense boundaries.
• Optimize Core Web Vitals (FCP, LCP, CLS) for real-world performance.
• Add filters and search that feel lightning-fast, without full reloads.
• Cache server data the right way — not too stale, not too fresh.
• Progressively enhance your UI with zero useState or useEffect overhead.
• Partial Pre-rendering to improve perceived speed.

Let’s be real — React Server Components can feel slow and clunky if you don’t know how to handle them properly. And poor loading UX? That’s a conversion killer.

But by the time you're done with this module, you'll have a UI that feels instant — no flickers, no spinners, no frustration.

🧩 What You’ll Build

Here is a quick tour of the app you will be building:

You’ll incrementally upgrade the Pulse analytics app step-by-step:

• Use Suspense to smooth out navigation
• Parallelize data fetching to kill bottlenecks
• Use React’s use() to read server data without wrappers
• Render Skeleton UIs to improve perceived speed
• Avoid full page reloads with the new Next.js form component
• Track transitions and stale states with React 19’s new tools
• Apply Optimistic UI patterns that feel magical
• Configure dynamic routes and stale times for smarter caching

And you’ll do all this without ever reaching for a spinner in JavaScript — unless you really want to.

Goal of this project

How you don't need to slap in a "use client" to build interactive web apps. You'll learn how to build interactive web apps using server components and several other techniques from Next.js. Things like,

• Why Suspense boundaries go in layouts
• Why not everything needs to be dynamic
• Why perceived speed is often more important than actual speed

This isn’t just a coding module. It’s a blueprint for building modern, interactive, scalable apps with confidence.
