Course overview

Next.js is a React framework for building fast, scalable, and search-friendly web applications. It provides routing, rendering options, data-fetching patterns, API routes, image optimization, and deployment workflows in a unified developer experience.

This course introduces React fundamentals, Next.js App Router, file-based routing, layouts, server and client components, data fetching, caching concepts, forms, API routes, authentication concepts, error handling, performance, testing, and deployment.

The proposed capstone is a Production Next.js Application for a chosen approved use case. It covers component architecture, dynamic routes, data handling, forms, validation, testing, documentation, and deployment readiness.

A production-ready Next.js application is more than a working interface. It needs clear component boundaries, secure data handling, accessible UI, useful error states, performance awareness, and maintainable code.

Prerequisites

This course is designed for learners with basic HTML, CSS, and JavaScript knowledge. Prior React experience is helpful but not mandatory.

  • Basic HTML and CSS knowledge.
  • Basic JavaScript knowledge including functions, arrays, and objects.
  • Basic understanding of the DOM and browser events.
  • Basic React knowledge is helpful.
  • Basic command-line knowledge is helpful.
  • Node.js and npm knowledge is helpful for project setup.

Readiness activity

Explain the difference between server-side rendering and client-side rendering. Identify two situations where a server component may be preferable to a client component.

Production Next.js Application

Build a complete Production Next.js Application for a chosen approved use case. Possible examples include a blog platform, portfolio website, product catalogue, recipe app, event listing site, dashboard, or another suitable educational web application.

Core project requirements

  • Define the application goal, users, and success criteria.
  • Plan pages, routes, components, and data requirements.
  • Create a responsive layout and navigation system.
  • Build reusable UI components.
  • Use App Router pages and dynamic routes.
  • Use server and client components appropriately.
  • Fetch data from an approved API or controlled data source.
  • Implement loading, empty, and error states.
  • Create at least one validated form.
  • Create an API route or integrate an approved external API.
  • Apply accessibility and responsive-design practices.
  • Use environment variables safely for configuration.
  • Test core user flows and document known limitations.
  • Prepare deployment instructions and a production checklist.

Quality requirements

  • Use clear component names and consistent file organization.

Next.js application workflow

Next.js projects are iterative. User feedback, performance findings, accessibility reviews, and changing requirements may require updates to routes, components, data handling, or deployment configuration.

Plan

Define the application

Identify users, pages, features, data needs, and success criteria.

Design

Create components

Build reusable, accessible, and responsive UI components.

Routing

Structure pages

Use layouts, dynamic routes, and navigation to organize the app.

Data

Connect information

Fetch, display, validate, and update data safely.

Quality

Test and improve

Review accessibility, performance, errors, and user experience.

Deploy

Release safely

Configure environments, build the app, deploy, and monitor it.

Server Components can reduce client-side JavaScript by rendering on the server, while Client Components are appropriate when a component needs browser interactivity or state.
