Benchmarks

Supercharging Your Next.js Workflow with AI

Have you ever spent an entire afternoon debating the architecture of a new project before writing a single line of business logic? That initial friction is a notorious productivity killer. In 2025, the debate between the Next.js App Router and the legacy Pages Router still creates a significant setup bottleneck. You’re forced to make foundational decisions, manually create a labyrinth of folders, and meticulously craft layout.tsx files, all while your actual application idea sits on the back burner. This boilerplate phase is where momentum is often lost.

This is where the paradigm shifts. Tools like Cursor are transforming the IDE from a passive text editor into an active development partner. By integrating large language models directly into your coding environment, you can now use natural language to command complex code generation. Instead of manually mkdir-ing your way to a working project, you can describe the desired structure and watch it materialize. This isn’t about replacing your expertise; it’s about offloading the repetitive, error-prone tasks to an AI assistant so you can focus on what truly matters: building features.

This guide is your shortcut to mastering that partnership. We’re providing a curated library of high-yield prompts specifically designed to eliminate the Next.js setup headache. You’ll learn the exact commands to generate the correct folder structure for both App and Pages Routers, and get layout.tsx files configured perfectly on the first try. By leveraging these prompts, you can slash your project initialization time from hours to minutes, ensuring you start building with a solid, error-free foundation.

Section 1: Understanding the Next.js Architecture: App Router vs. Pages Router

Before you can write a single effective prompt for Cursor, you need to make a fundamental architectural decision: which routing paradigm will your project use? This isn’t just a matter of preference; it dictates the entire file structure, component behavior, and even how you handle data fetching. Getting this choice wrong in your prompt will send the AI down a completely wrong path, generating incompatible code that you’ll have to scrap and start over. Let’s demystify the two approaches so your AI commands are precise and productive.

Defining the Two Paradigms: A Tale of Two Directories

At its core, the difference is a shift from client-side logic to server-first architecture.

The Pages Router is the classic, battle-tested system you might know from previous Next.js versions. It uses a pages/ directory where the file path directly maps to the URL endpoint. For example, pages/about.tsx becomes yourdomain.com/about. It’s intuitive and relies heavily on client-side hooks like useEffect and getServerSideProps for data management. Layouts are handled by wrapping components, which can become cumbersome in larger applications with nested routes.

The App Router, introduced in Next.js 13 and now the default, is a revolutionary shift built on React Server Components (RSC). It uses an app/ directory and introduces a more flexible, file-based routing system that supports layouts, templates, and error states that are shared across routes. The key architectural difference is that components are server-side by default. This means your initial page load is pure, lightweight HTML, and you only opt-in to client-side interactivity with the "use client" directive. This model fundamentally changes how you think about hooks and data fetching, moving them closer to the server for better performance and SEO.

Why Your AI Prompt Must Choose a Side

This is where most developers stumble when using AI for code generation. You cannot be vague. If you ask Cursor to “create a new Next.js layout,” you’ll get a generic response that could be for either router, and it will likely be wrong.

To get a usable result, your prompt must explicitly state the target architecture. For example:

• Vague Prompt (Will Fail): “Generate a layout file for my Next.js app.”
• Precise Prompt (Will Succeed): “Generate a root layout.tsx file for a Next.js App Router project. The layout should include a <head> section with a default title and description, and a <body> that contains a main content area.”

The difference is stark. The App Router expects a layout.tsx file with specific children props and metadata handling, while the Pages Router uses a custom _app.tsx file. By specifying the router, you give the AI the precise context it needs to generate the correct file name, location (app/layout.tsx vs. pages/_app.tsx), and internal structure. Your prompt is only as good as the context you provide.

Navigating Existing Projects and Migrations

Very few of us start with a blank slate in 2025. You’re likely working on an existing codebase. Here’s how to adapt your prompting strategy for both scenarios:

1. Scaffolding New Features in a Pages Router App: If your project is still on the Pages Router, you can still leverage AI effectively. Your prompts must respect the existing structure. For instance: “Create a new pages/dashboard/settings/profile.tsx file. This page should use getServerSideProps to fetch user data and render a form component.”

2. Generating Migration Scaffolding: Migrating to the App Router is a significant undertaking. You can use AI to help you plan and scaffold the new structure without breaking the old one. A great prompt would be: “Generate the new app directory structure for a migration. Create a layout.tsx and page.tsx that will coexist with our existing pages directory. Include the necessary layout.tsx for the new app/dashboard section.” This allows you to build out the new structure incrementally.

SEO & Performance Implications You Can Prompt For

The choice of router has a direct and measurable impact on your site’s Core Web Vitals and SEO. The App Router’s server-first nature is a significant advantage. Because it sends fully rendered HTML to the browser by default, it dramatically improves First Contentful Paint (FCP) and Largest Contentful Paint (LCP) scores.

You can actually use AI to optimize these advantages. For the App Router, you can prompt for metadata generation that is far more powerful than the old next/head:

• Prompt for App Router SEO: “Create a generateMetadata function in my app/products/[id]/page.tsx. It should fetch product data from the API and set the title, description, and openGraph images dynamically.”

For the legacy Pages Router, you can still get help, but the approach is different:

• Prompt for Pages Router SEO: “Update the pages/products/[id].tsx file to use next/head for setting a dynamic page title and meta description based on the product object from getServerSideProps.”

Golden Nugget for AI Prompting: The most common mistake I see is developers asking for a “Next.js component” without specifying the router’s data-fetching method. This forces the AI to guess. Always preface your code generation prompts with the router type and the data strategy you intend to use (e.g., “For an App Router page, generate a Server Component that fetches data using async/await directly in the component body”). This single detail will save you hours of refactoring.

Section 2: The Core Prompting Strategy: Context, Constraints, and Clarity

The difference between a prompt that generates a perfect, production-ready setup and one that produces a tangled mess of code isn’t luck—it’s strategy. A generic request like “create a Next.js project” will get you a generic result. To truly leverage Cursor as a senior developer’s assistant, you need to think like a project manager assigning a task. You must provide clear context, firm constraints, and unambiguous clarity. This is the foundation of effective AI-assisted development.

The Anatomy of a Perfect Prompt

Every high-yield prompt you write should follow a simple but powerful structure: Role, Task, and Constraints. Think of it as giving your AI assistant a clear brief before they start work.

• Role: This is the most overlooked element. By starting with “Act as a Senior Next.js Developer specializing in performance and accessibility,” you prime the AI to adopt a specific mindset. It will favor best practices, write more semantic HTML, and choose more robust solutions over quick hacks.
• Task: This is the “what.” Be explicit. Instead of “set up auth,” try “Generate the folder structure for a Next.js App Router authentication flow using Server Actions.” The more specific your task, the less room there is for misinterpretation.
• Constraints: This is the “how.” This is where you lock down the environment to match your project’s reality. List your dependencies, TypeScript requirements, and styling libraries. For example: “Use TypeScript with strict mode enabled, style with Tailwind CSS and the cn utility, and assume next-auth v5 is installed.”

Example Prompt:

“Act as a Senior Next.js Developer. Generate the folder structure for a protected dashboard route in the App Router. The task is to create a /dashboard layout that only authenticated users can access. Constraints: Use TypeScript, implement the layout as a Server Component, and use next-auth v5 for session management. The layout should include a sidebar and a main content area.”

Iterative Prompting vs. One-Shot Generation

While it’s tempting to ask the AI to “build my entire application with authentication,” this is a recipe for disaster. Complex tasks should be broken down into a sequence of smaller, focused prompts. This iterative approach gives you control, allows for course correction, and produces far more reliable results.

Imagine you need a full authentication setup. A one-shot prompt might generate a confusing mix of client and server components, incorrect file placements, and outdated patterns. A better, iterative strategy looks like this:

1. Prompt 1 (Structure): “Generate the App Router folder structure for authentication. I need a /login page, a /register page, and a /dashboard route that should be protected.”
2. Prompt 2 (Layout): “Now, create the layout.tsx file for the /dashboard route. It should be a Server Component that checks for a user session using next-auth and redirects to /login if none exists.”
3. Prompt 3 (Page): “Generate the page.tsx for the /dashboard route. Fetch user data from a mock API endpoint /api/user and display it in a card component.”

This methodical process ensures each piece is correct before moving to the next, mirroring how a human developer would actually build the feature.

Handling Edge Cases in Setup

Modern Next.js, especially with the App Router, introduces powerful but complex patterns. Prompting for these requires surgical precision. You need to name the feature correctly and describe its behavior.

• Dynamic Segments: For a blog or e-commerce site, you’ll need dynamic routes. Be explicit: “Create a products/[slug] folder. Inside, generate a page.tsx that fetches a single product based on the slug parameter from the URL.”
• Catch-All Routes: For handling unpredictable URL structures, like a file system: “Generate a [[...slug]] catch-all route. The page.tsx should display the full path segments as a breadcrumb.”
• Parallel and Intercepting Routes: These are advanced patterns for modals and nested layouts. Your prompt must be unambiguous: “Create a parallel route using the @auth slot for the (auth) group. This slot should render a modal component at the /login route, which intercepts the main feed view.”

By using the correct file and folder naming conventions directly in your prompt, you guide the AI to the exact modern Next.js feature you need.

Common Prompting Mistakes to Avoid

Even with a good structure, small oversights can derail your results. Here are the most common pitfalls I see developers make:

• Vague Styling Instructions: Never assume the AI knows your styling setup. Always specify “Tailwind CSS,” “CSS Modules,” or “Styled Components.” A prompt for a “button” without this context could generate inline styles, utility classes, or a styled-component, leading to inconsistency.
• Forgetting TypeScript: If you need strict typing, you must ask for it. A prompt like “generate a component for user data” might return any types or no types at all. Specify “Generate a TypeScript component with defined interfaces for the User object.”
• Ambiguous Data Fetching: In the App Router, the distinction between Server and Client Components is critical. A common mistake is asking for a component that fetches data without specifying where the fetch should happen. A better prompt is: “Create a Server Component that fetches a list of posts and passes the data to a Client Component for interactivity.”
• Ignoring Edge Cases: Don’t forget to prompt for loading states and error handling. A simple addition like “Also, generate a loading skeleton and a basic error boundary for this route” can save you significant follow-up work and make the generated code immediately more robust.

Mastering these prompting fundamentals is the key to transforming Cursor from a simple code completer into a powerful scaffolding engine. It’s a skill that pays dividends in speed, accuracy, and code quality.

Section 3: Prompt Library: Scaffolding the Boilerplate (App Router)

This is where theory meets practice. You’ve seen the power of AI-assisted development; now it’s time to wield it. The following prompts are not just copy-paste commands—they are battle-tested starting points I use in my own projects to establish a robust, scalable foundation in minutes. Each prompt is designed to be specific, context-aware, and focused on the conventions of the modern Next.js App Router.

The “Hello World” Foundation Prompt

Every new project begins with the same essential structure. Instead of manually creating each directory and file, we can instruct Cursor to lay the groundwork for us. This prompt generates a clean, production-ready starting point that separates your UI components from your application logic, a foundational best practice for scalability.

Prompt to Use:

“Generate a Next.js 14 App Router folder structure using TypeScript and Tailwind CSS. The root of the app should be in an app directory. Inside app, create a layout.tsx file and a page.tsx. The layout.tsx must be a Server Component that defines the root layout, including the <html> and <body> tags, and a global stylesheet import. Also, create a components directory at the project root and inside it, generate a simple Navbar.tsx component using Tailwind classes for basic styling.”

Why This Prompt Works:

• Explicit Router Version: Specifying “Next.js 14” and “App Router” ensures the AI generates the correct file-based routing convention, avoiding legacy Pages Router patterns.
• Component Separation: By explicitly asking for a components folder at the root (outside of app), you’re establishing a clear separation between shared UI components and route-specific components. This is a critical architectural decision that prevents code duplication down the line.
• Server Component by Default: The prompt specifies that layout.tsx should be a Server Component. This is a crucial detail for performance and security, as it keeps your layout on the server by default, reducing the JavaScript bundle sent to the client.
• Golden Nugget - The Global Stylesheet Import: A common pitfall for developers new to the App Router is forgetting to import the global stylesheet in the root layout.tsx. The app directory requires this import to be present in the root layout to be applied globally. This prompt bakes that best practice in from the very first generation, saving you a debugging headache when your Tailwind classes don’t render.

Setting Up Authentication Scaffolding

Most modern applications require user authentication. Manually structuring the routes, protected pages, and API handlers is tedious and error-prone. This prompt chain helps you scaffold a complete authentication flow, whether you’re using NextAuth.js, Clerk, or a custom solution.

Prompt to Use:

“Scaffold the folder structure for a Next.js App Router project that uses authentication. Create an (auth) route group for public-facing pages like /login and /register. Inside this group, create a layout.tsx that only shows a centered form and a page.tsx for each route.

Then, create a (dashboard) route group for protected pages. Inside it, generate a layout.tsx and a page.tsx for a /dashboard route. Add a placeholder middleware.ts file at the project root that demonstrates how to protect all routes within the (dashboard) group by checking for a user session and redirecting to /login if one doesn’t exist.”

Why This Prompt Works:

• Route Groups ((auth), (dashboard)): This prompt leverages a powerful App Router feature. Route groups allow you to organize routes without affecting the URL structure. This is essential for applying different layouts (e.g., a simple auth layout vs. a complex dashboard layout) to different sections of your app.
• Proactive Middleware: Instead of just creating pages, this prompt asks for a middleware.ts file. This demonstrates a deeper understanding of Next.js security patterns. It shows you how to think about protecting routes at the edge, before a page is ever rendered. While the generated code is a placeholder, it establishes the correct architectural pattern for you to build upon.
• Contextual Layouts: By asking for a layout.tsx inside each route group, you’re ensuring that the UI context is correctly scoped. The auth layout won’t leak into the dashboard, and vice-versa. This is a core principle of the App Router that this prompt enforces automatically.

Generating Metadata and SEO Config

In 2025, SEO is not an afterthought; it’s a core feature. The App Router’s generateMetadata function is a game-changer for this. This prompt shows you how to automate the creation of rich, shareable metadata for your pages.

Prompt to Use:

“In the root app/layout.tsx file, replace the static <title> tag with the generateMetadata function. Configure it to return a dynamic title based on the page, using a template like MyApp - {pageTitle}. Also, add comprehensive Open Graph metadata, including title, description, images (use a placeholder URL), and type: 'website'. Ensure the description is pulled from a constant defined at the top of the file.”

Why This Prompt Works:

• Dynamic & Static Metadata: This prompt teaches the AI to generate both a title template (dynamic) and static Open Graph properties. This is the professional way to handle metadata, ensuring every page has a unique but consistent title while sharing a common social media preview.
• Code Organization: By asking the AI to pull the description from a constant, you’re promoting clean, maintainable code. If you need to change your site’s description in the future, you only have to edit it in one place.
• Future-Proofing: The generateMetadata function is the standard for SEO in modern Next.js. This prompt ensures you’re building your project on the current, recommended API, avoiding deprecated patterns like the next/head component.

Integrating UI Libraries (Shadcn/UI & Tailwind)

Setting up a component library like Shadcn/UI with Tailwind CSS involves several configuration steps that can be tricky. This prompt helps you automate the initialization and ensure your global styles are correctly configured to handle design tokens and theming.

Prompt to Use:

“Initialize a new Next.js project with Tailwind CSS. Then, run the npx shadcn-ui@latest init command to set up Shadcn/UI. Configure it with the following options: use a ./components.json file, use TypeScript, use the default Tailwind CSS style, and set the cssVariables to true. Finally, open app/globals.css and ensure the @layer directives for base, components, and utilities are correctly set up to include Shadcn/UI’s styles and any custom Tailwind utilities.”

Why This Prompt Works:

• End-to-End Automation: This prompt goes beyond just adding a package. It guides the AI through the interactive shadcn-ui initialization process, specifying the exact configuration choices I’ve found to be most effective for a scalable project (cssVariables: true is key for theming).
• CSS Architecture Insight: The prompt explicitly mentions the @layer directives in globals.css. This is a critical detail. Shadcn/UI and other modern libraries rely on these layers to correctly inject their component styles into the Tailwind pipeline. Getting this right prevents bizarre styling conflicts and ensures your custom utilities can override library defaults when needed.
• Golden Nugget - cssVariables: true: This is a pro-level choice. When you set Shadcn/UI to use CSS variables, it generates a variables.css file that defines your theme’s colors, spacing, and radii as native CSS custom properties. This makes building a light/dark mode switch or a custom theme later incredibly simple—you just change the variable values in one place. This prompt bakes that future-proofing into your project from day one.

Section 4: Prompt Library: Scaffolding the Boilerplate (Pages Router)

While the Next.js App Router is the modern standard, a significant portion of enterprise-level applications still rely on the Pages Router for its mature ecosystem and predictable data-fetching patterns. If you’re inheriting a legacy project or maintaining a codebase that hasn’t migrated, you can still leverage Cursor’s power to accelerate development. The key is to be explicit about the file structure and the specific boilerplate required for _app.tsx, _document.tsx, and dynamic routes. This section provides a set of battle-tested prompts designed to generate robust, type-safe scaffolding for the Pages Router architecture.

Generating the Core Pages Directory Structure

The foundation of any Pages Router application is its directory structure. A common mistake is creating a flat pages folder, which becomes unmanageable. This prompt instructs the AI to generate a scalable structure from the outset, separating API routes, static pages, and dynamic content. It also automatically creates the critical root-level files that control global application behavior.

Prompt for Core Structure:

“Scaffold the following folder structure for a Next.js project using the Pages Router. Ensure all new files are TypeScript (.tsx, .ts):

pages/
  _app.tsx
  _document.tsx
  index.tsx
  api/
    hello.ts
  blog/
    index.tsx
    [slug].tsx

For pages/api/hello.ts, generate a basic type-safe API route that returns a JSON object with a message property. For pages/index.tsx and pages/blog/index.tsx, just create a simple functional component with an h1 tag.”

This prompt provides a clear, unambiguous blueprint. The AI understands the convention of _app.tsx and _document.tsx as special files and generates the necessary dynamic route placeholder [slug].tsx. This single command saves you from creating at least six files and directories manually, ensuring the project starts with a clean, organized structure.

Customizing _app.tsx with Global Providers

_app.tsx is the heart of your application’s global state. It’s where you wrap your entire application with providers for state management, theming, or analytics. Manually nesting these providers is tedious and error-prone. This prompt automates the process, demonstrating an expert understanding of how to structure a real-world Next.js application.

Prompt for Global Providers:

“Refactor the pages/_app.tsx file to include the following global providers:

1. Wrap the entire component tree with a SessionProvider from next-auth/client. Assume the session data is fetched from useSession.
2. Wrap the content inside SessionProvider with a ThemeProvider from next-themes. Configure it to support both light and dark modes.
3. Add a QueryClientProvider from @tanstack/react-query to enable global server-state management.

Ensure all necessary hooks and imports are added correctly. The final structure should be a clean, nested provider pattern.”

By specifying the exact libraries and their nesting order, you prevent the AI from making assumptions. This prompt results in a production-ready _app.tsx that handles authentication, theming, and data fetching out of the box. Golden Nugget: A common pitfall when prompting for _app.tsx is forgetting to pass the pageProps down to the wrapped component. This prompt’s implicit request for a “clean, nested provider pattern” encourages the AI to generate the correct syntax, but always double-check that the final render includes <Component {...pageProps} />.

Scaffolding Dynamic Routes with Data Fetching

Dynamic routing is where the Pages Router shines. Generating the boilerplate for getStaticProps or getServerSideProps with the correct TypeScript types for props and params is a repetitive task. This prompt streamlines creating a blog post page that fetches data based on a URL slug.

Prompt for Dynamic Route Boilerplate:

“Create a file at pages/blog/[slug].tsx. Inside, generate a TypeScript functional component that accepts post as a prop.

Below the component, export an async getStaticProps function. This function should:

1. Accept a context object with params typed for the [slug] route.
2. Fetch data from a mock function getPostBySlug(context.params.slug).
3. Return a props object containing the fetched post data.

Also, export an getStaticPaths function that returns a list of possible slugs (e.g., ‘hello-world’, ‘ai-prompts’) for pre-rendering.”

This prompt is powerful because it asks the AI to handle both the component and the data-fetching logic in one go. It enforces TypeScript best practices by explicitly mentioning the typing of context.params. This ensures that the generated code is not just functional but also type-safe, catching potential runtime errors during development.

Generating Full CRUD API Routes

Next.js API routes allow you to build a full backend within your frontend project. Writing the boilerplate for handling different HTTP methods (GET, POST, PUT, DELETE) and defining the request/response types is a perfect task for an AI assistant. This prompt demonstrates how to generate a complete, type-safe CRUD endpoint.

Prompt for a CRUD API Route:

“Generate a complete, type-safe CRUD API route at pages/api/posts/[id].ts.

• Imports: Import NextApiRequest and NextApiResponse from next.
• Handler: Create a default export function that takes req and res as arguments.
• Logic:
  • For GET requests, return a mock post object.
  • For PUT requests, parse the request body and return an updated post object.
  • For DELETE requests, return a 200 status with a success message.
  • For any other method, return a 405 Method Not Allowed status.
• Types: Define and use TypeScript interfaces for the request body (for PUT) and the response objects to ensure type safety.”

This prompt is a masterclass in delegation. It offloads the entire logical structure of the API handler, including error handling for unsupported methods. The resulting file is robust, follows best practices, and is immediately ready for you to connect to a database or other services, saving you significant setup time.

Section 5: Advanced Cursor Techniques: Refactoring and Debugging Layouts

You’ve successfully scaffolded your Next.js application, but the initial setup is just the launchpad. The real complexity begins when you need to evolve that structure—refactoring components, fixing elusive bugs, and scaling your codebase without it collapsing under its own weight. This is where moving from simple generation to intelligent iteration with Cursor becomes a superpower. We’ll explore the specific prompts that turn your AI assistant from a code generator into a senior pair programmer capable of debugging layout shifts and architecting for scale.

The “Refactor” Prompt: From Monolith to Modular Architecture

One of the most common growing pains in a Next.js project is a bloated layout.tsx. What starts as a simple container quickly becomes a “god component” cluttered with navigation, authentication state, and marketing footers. The key to managing this is component composition, and you can guide Cursor to perform this surgery with precision.

Instead of just asking, “Add a sidebar,” you need to provide context and a clear directive. Here’s a prompt structure I use repeatedly in production:

“I need to refactor app/dashboard/layout.tsx. It’s currently a monolithic file. Please perform the following steps:

1. Identify the distinct UI regions: the main <header>, the <nav> sidebar, and the primary content area.
2. Extract each region into its own functional component.
3. Create these new components in a logical directory structure: components/dashboard/shared/ (e.g., DashboardHeader.tsx, DashboardSidebar.tsx).
4. Import and render these new components back into the original layout.tsx.
5. Bonus: As you extract the DashboardSidebar, convert its inline Tailwind classes into a dedicated sidebar.module.css file for better separation of concerns.”

This prompt works because it’s a set of explicit, actionable commands. You’re not just asking for a change; you’re dictating the architecture. A crucial “golden nugget” here is to always ask the AI to verify imports and prop passing after a refactor. A common mistake is forgetting to pass necessary props (like user data) from the layout down to the newly extracted components. I once spent an hour debugging a broken profile menu only to realize the AI extracted the component but didn’t carry over the session prop. Now, I always append: “Ensure any required props from the parent layout are correctly passed to the new child components.”

Debugging Layout Shifts and Hydration Errors

Few things are more frustrating than a perfectly styled component that flashes and shifts its position on load. These Cumulative Layout Shift (CLS) issues and React hydration errors are notoriously difficult to debug because they often stem from mismatches between server-rendered HTML and the client-side JavaScript. Your prompt here needs to act as a diagnostic tool.

When you encounter a hydration error like Text content does not match between server and client, your first instinct might be to manually hunt for the culprit. Instead, let Cursor do the heavy lifting:

“Analyze this layout.tsx for potential hydration mismatches. Specifically, look for:

• Components that rely on browser-only APIs like window or document (e.g., checking window.innerWidth for responsive logic).
• Dynamic values that will be different on the server vs. client, such as new Date() or Math.random().
• Directly rendered emojis or special characters that might be handled differently by the server and browser.

For each issue you find, explain why it causes a hydration error and provide the corrected code, using useEffect and useState to gate client-side logic where necessary.”

This prompt forces the AI to act as a static analysis tool, checking for a known list of anti-patterns. It doesn’t just fix the code; it teaches you the underlying cause. For layout shifts (CLS), a similar approach works wonders. Ask Cursor: “Review this component for CLS risks. Are images missing width and height props? Are fonts loading late and causing a flash of unstyled text (FOIT)? Suggest a fix using next/image and a strategy for preloading fonts.” This proactive analysis saves you from poor Core Web Vitals scores down the line.

Adding Global State Management

As your application grows, passing props through multiple component layers (prop drilling) becomes unmaintainable. This is the signal to introduce a global state manager like Zustand. While it’s a simple library, setting up the store, the provider, and typing it correctly is boilerplate you don’t want to write manually.

Here’s the prompt that automates the entire integration:

“Integrate Zustand for global state management into this Next.js 14 project.

1. Install the zustand package.
2. Create a store directory at the project root.
3. Inside store, create a userStore.ts file. Define a simple store that holds a user object and has setUser and clearUser actions. Use TypeScript interfaces for the state shape.
4. Modify the root app/layout.tsx to import the Zustand StoreProvider (if using the Next.js App Router pattern) or wrap the <Component /> in pages/_app.tsx.
5. Provide a clear example of how to use the useUserStore hook in a client component.”

This prompt is powerful because it’s a full-stack command. It handles the package installation, file creation, state logic, and the critical step of wiring it into the Next.js rendering pipeline. A key detail I’ve learned is to be explicit about TypeScript. Without it, you might get a store that works but lacks type safety, defeating the purpose of using a robust framework. By asking for interfaces, you ensure the generated code is production-ready.

Section 6: Best Practices for AI-Assisted Next.js Development

Using AI to generate Next.js boilerplate feels like a superpower, but like any power, it requires discipline. A developer who blindly accepts every line of code from an AI is setting themselves up for security vulnerabilities, inconsistent architecture, and technical debt. The goal isn’t to replace your expertise but to augment it. This section outlines the critical practices that separate a junior prompt-copier from a senior AI-augmented architect. These are the guardrails and accelerators I’ve developed through hundreds of AI-assisted project setups.

Security First: The Immutable Rule of Secrets

The single most dangerous habit you can develop is pasting your actual API keys, database connection strings, or any real secrets directly into an AI prompt. Even with models that claim to have no memory, this is a catastrophic security risk. The AI might embed these secrets directly into the generated code, which could then be committed to a public repository or logged in an error report.

Instead, your workflow must be to instruct the AI to create a template for your environment variables. This is a subtle but crucial distinction.

The Secure Prompting Pattern: Instead of: “Create a .env.local file with my Supabase URL https://xyz.supabase.co and anon key my-secret-key…” Use: “Generate a .env.local.example file for a Next.js project using Supabase. Include placeholders for NEXT_PUBLIC_SUPABASE_URL and NEXT_PUBLIC_SUPABASE_ANON_KEY. Then, show me how to reference these variables in a supabase.ts client initialization file using process.env.”

This approach achieves two things:

1. It keeps secrets out of the AI context. You create the real .env.local file yourself and never share its contents.
2. It teaches the correct pattern. The AI generates a reusable, shareable template for your team, and the code it produces correctly uses process.env to access the variables, which is the standard for Next.js.

Golden Nugget: Always add .env.local to your .gitignore file. This is a non-negotiable step. The .env.local.example (or .env.example) is the only environment file that should ever be committed to version control. This ensures any developer can clone your repo and know exactly which variables they need to set up without ever seeing your actual secrets.

Code Review is Still King: Your AI-Generated Code Checklist

AI-generated code is a fantastic first draft, but it is never the final product. It’s your job to be the expert reviewer. Think of the AI as a brilliant but sometimes naive junior developer who has read every book but lacks real-world context. Before you integrate any AI-generated structure, run it through this mental checklist:

• Type Safety Verification: Did the AI generate any types? Next.js and TypeScript thrive on strict typing. Manually inspect the generated files and replace any any with specific interfaces or types. This single step can prevent a huge class of runtime errors.
• Circular Dependency Check: In a complex folder structure, especially with shared types or utils directories, it’s easy to create circular dependencies. Run a tool like madge or simply trace your imports manually to ensure file A doesn’t import from file B if file B also imports from file A. This can cause baffling build errors.
• Layout and Component Logic: When generating layout.tsx files, does the AI correctly pass the children prop? Does it wrap client components in 'use client' directives where necessary? A common mistake is generating server components that try to use browser-only APIs.
• Security Audit: Scan for common vulnerabilities. Is the AI using dangerouslySetInnerHTML without sanitization? Are there any hardcoded secrets we just discussed? Is it using unescaped user input in SQL queries (if it generates API routes with DB logic)?
• Performance Implications: Does the generated code trigger unnecessary re-renders? Is it fetching data on a component that should be a Server Component? A quick review here can save hours of performance debugging later.

Maintaining Consistency: Your Project’s Style Guide Prompt

One of the biggest challenges in a project’s lifecycle is maintaining consistency, especially as a team grows. When you’re using AI to generate new features or components, you’ll get inconsistent results unless you provide a consistent context. The solution is to create a “style guide” prompt.

This is a foundational prompt you can feed to Cursor (or any AI assistant) at the start of a new feature or session to align it with your project’s standards.

Example Style Guide Prompt:

“Before generating any code, please adopt the following project conventions:

• File Naming: Use kebab-case for file names (e.g., user-profile.tsx) and PascalCase for component and type names inside the files.
• Components: All components should be functional and typed with TypeScript interfaces. Prefer Server Components by default. Only use the 'use client' directive when absolutely necessary (e.g., for state, effects, or browser APIs).
• Styling: Use Tailwind CSS utility classes exclusively. Avoid creating CSS modules unless a component has highly complex, dynamic styles. Use a cn utility function for conditional class names.
• Imports: Group imports in this order: 1) External libraries, 2) Internal components, 3) Internal types/utils, 4) Styles/assets. Use absolute imports from the root (@/components/ui/button) instead of relative paths (../../../components/ui/button).
• State Management: For global state, use Zustand. For server state, use TanStack Query (React Query). Do not use React Context for global state management.”

By providing this context, you transform the AI from a generic code generator into a specialized assistant that understands your project’s DNA. This dramatically reduces the time you spend on refactoring and enforcing conventions.

The Future of IDEs: From Syntax Writer to System Architect

Tools like Cursor represent a fundamental shift in the role of a software developer. For decades, a developer’s primary value was tied to their ability to memorize syntax, API endpoints, and boilerplate patterns. We spent a significant portion of our mental energy on the how.

The rise of AI-assisted IDEs is moving us toward a future where the most valuable skill is not writing syntax, but architecting systems.

Your job is no longer to be the one who types out every line of code. Your job is to become the master of delegation. You are the architect who designs the blueprint, defines the constraints, and assigns tasks to your AI agents. The quality of your output is now directly proportional to the quality of your prompts and your ability to review, refine, and integrate the generated work.

Mastering the art of the prompt is the new essential skill. It’s about knowing what to ask for, how to ask for it securely, and how to verify the result. You’re moving from being a line-by-line writer to a high-level conductor, orchestrating a symphony of AI-generated components into a robust, scalable, and secure application.

Conclusion: Your Blueprint for Rapid Development

You’ve now seen how a strategic approach to prompting transforms a blank directory into a production-ready Next.js application. The core lesson is that specificity is your superpower. Vague requests yield generic code, but detailed prompts that define architectural choices—like the App Router’s (auth) route group or the cssVariables: true setting in Shadcn/UI—produce robust, scalable foundations. We’ve also highlighted the critical structural differences between the App and Pages routers, showing you how to prompt for layouts and middleware that enforce security and UI consistency from the very first line of code.

The Efficiency Multiplier: From Hours to Minutes

Think about the last time you started a new project. How many hours did you spend on npm install, folder creation, and wiring up providers? By automating this tedious setup phase, you’re not just saving time; you’re creating an efficiency multiplier. Instead of wrestling with boilerplate, you can immediately focus on the unique business logic and user experience that defines your application. This workflow shifts your role from a manual laborer to a high-level architect, directing AI agents to handle the repetitive scaffolding while you concentrate on innovation.

The most powerful prompt is the one you customize. The true “golden nugget” here isn’t just the code—it’s the mindset of iterative prompting. Start with the templates provided, but don’t stop there. Run the generated code, identify a friction point, and go back to the AI with a refinement: “Great, now refactor the layout.tsx to include a persistent sidebar.”

Your next steps are clear:

• Copy the prompts from this guide directly into Cursor.
• Adapt them for your specific tech stack—swap Prisma for Drizzle, or Tailwind for styled-components.
• Experiment relentlessly. The best developers in 2025 aren’t just writing code; they’re engineering prompts that write code for them. You now have the blueprint to build faster than ever before.

Critical Warning

Frequently Asked Questions

Q: Why is it critical to specify App Router vs. Pages Router in AI prompts

The two routers have fundamentally different file structures and component behaviors; mixing them results in broken code that requires a full rewrite

Q: Can I use these prompts for legacy Next.js projects

Yes, but you must explicitly specify ‘Pages Router’ in your prompt, as modern AI models default to the newer App Router architecture

Q: Does Cursor AI actually write the files for me

Cursor acts as an active partner; while it generates the code in the chat, you typically use its ‘Apply’ or ‘Terminal’ features to write the files to your disk automatically
