Introduction

If you have been following our Claude Code Mastery Series, you already know the basics: installation, authentication, and navigating your first session. Part 1 gave you the foundation. Now it is time to build something real.

This article walks you through an entire full-stack development workflow using Claude Code. We will scaffold a project from scratch, build a React frontend with Tailwind CSS, wire up a backend API, connect a PostgreSQL database through Prisma, write tests at every level, and prepare the whole thing for production deployment. Every prompt in this article is something you can type directly into your terminal and run.

In our experience at Luminous Digital Visions, the developers who get the most out of Claude Code are the ones who treat it as a pair programmer rather than a magic wand. You still need to understand what you are building. But Claude Code handles the mechanical parts (the boilerplate, the configuration files, the repetitive CRUD logic) so you can focus on architecture decisions and user experience.

What You Will Build

By the end of this guide, you will have:

  • A fully scaffolded Next.js or Vite project with TypeScript and Tailwind CSS
  • A working frontend with components, routing, and state management
  • A backend API with Express or Fastify, including middleware and validation
  • A PostgreSQL database with Prisma ORM, migrations, and seed data
  • Unit tests, integration tests, and end-to-end tests
  • A production-ready deployment pipeline

Prerequisites

  • Claude Code installed and authenticated (covered in Part 1)
  • Node.js 18+ installed
  • Basic familiarity with the terminal
  • A code editor (VS Code, Cursor, or any editor you prefer)
ℹ️

Info: Claude Code uses Anthropic's current Claude models and can understand large codebases, execute multi-step tasks, and reason about complex architectural decisions. You invoke it with the claude command in your terminal.

Project Scaffolding with Claude Code

The first step in any full-stack project is scaffolding. This is where Claude Code saves you the most time upfront. Instead of running create-next-app and manually configuring a dozen settings, you describe what you want in plain language.

Scaffolding a Next.js Application

Open your terminal, navigate to your projects directory, and run:

claude "Scaffold a Next.js 15 app with TypeScript, Tailwind CSS, and the App Router. Use src/ directory structure. Include ESLint and Prettier configs. Set up path aliases for @/components, @/lib, and @/types."

Claude Code will create the project, install dependencies, and configure everything. Watch the output. It will show you every file it creates and every command it runs. You will end up with a structure like this:

my-app/
├── src/
│   ├── app/
│   │   ├── layout.tsx
│   │   ├── page.tsx
│   │   └── globals.css
│   ├── components/
│   ├── lib/
│   └── types/
├── public/
├── tailwind.config.ts
├── tsconfig.json
├── .eslintrc.json
├── .prettierrc
└── package.json

Scaffolding with Vite and React

If you prefer Vite for a single-page application, the prompt looks different but the workflow is the same:

claude "Create a React app using Vite with TypeScript, Tailwind CSS, and React Router v7. Set up the src folder with directories for components, pages, hooks, services, and types. Add a basic routing structure with Home, About, and Dashboard pages."

Scaffolding an Express Backend

For standalone backend projects, Claude Code handles that too:

claude "Create an Express.js backend with TypeScript. Include folder structure for routes, controllers, middleware, and services. Set up CORS, helmet for security, rate limiting, and a health check endpoint. Add nodemon for development and a proper tsconfig."
💡

Tip: You can scaffold both frontend and backend in a single monorepo. Just ask Claude Code to set up a workspace with separate packages. Something like: claude "Create a monorepo with pnpm workspaces containing a Next.js frontend and an Express backend. Share TypeScript types between them."

What Good Scaffolding Prompts Include

The difference between a mediocre scaffold and a great one comes down to specificity. Here is what to include:

  • Framework and version — "Next.js 15" not just "Next.js"
  • Language — "TypeScript" with strict mode
  • Styling approach — "Tailwind CSS" or "CSS Modules" or "styled-components"
  • Directory structure — Specify if you want src/, feature-based folders, or barrel exports
  • Tooling — ESLint, Prettier, path aliases, environment variable setup
  • Initial pages or routes — Give Claude Code something concrete to generate

Frontend Development Workflows

With your project scaffolded, the real work begins. Frontend development with Claude Code is a conversation. You describe what you need, review what it produces, and iterate.

Creating Components

Start with a concrete prompt. Vague requests produce vague components.

claude "Create a responsive navigation bar component in src/components/Navbar.tsx. It should include a logo on the left, navigation links in the center (Home, Features, Pricing, Contact), and a Sign In / Get Started button group on the right. On mobile, collapse into a hamburger menu with a slide-out drawer. Use Tailwind CSS. Make it sticky on scroll."

Claude Code will generate the component, handle the mobile menu state with useState, add the hamburger icon, and style everything with Tailwind utility classes. The result is typically a working component on the first try.

Styling with Tailwind CSS

One of the strongest areas for Claude Code is Tailwind. It knows the utility classes deeply and applies them correctly. You can ask for specific design patterns:

claude "Style the hero section on the homepage. Use a gradient background from indigo-600 to purple-700. Center the heading and subheading. Add a call-to-action button with hover animation. Make it responsive — full viewport height on desktop, auto height on mobile with appropriate padding."

The generated code might look something like this:

export default function Hero() {
  return (
    <section className="min-h-screen flex items-center justify-center bg-gradient-to-br from-indigo-600 to-purple-700 px-4 py-20 md:py-0">
      <div className="text-center max-w-3xl mx-auto">
        <h1 className="text-4xl md:text-6xl font-bold text-white mb-6">
          Build Faster with AI
        </h1>
        <p className="text-lg md:text-xl text-indigo-100 mb-8">
          Ship production-ready applications in hours, not weeks.
        </p>
        <button className="bg-white text-indigo-700 font-semibold px-8 py-3 rounded-lg hover:bg-indigo-50 transition-colors duration-200 hover:scale-105 transform">
          Get Started Free
        </button>
      </div>
    </section>
  );
}

State Management

For state management, Claude Code can set up anything from simple useState patterns to full global state with Zustand or Redux Toolkit. In our experience at Luminous Digital Visions, Zustand hits the sweet spot for most projects: less boilerplate than Redux, more structure than Context alone.

claude "Set up a Zustand store for user authentication state. Include user profile data, login/logout actions, loading state, and error handling. Create a useAuth hook that components can use. Put the store in src/lib/stores/authStore.ts."

Routing and Page Structure

For Next.js App Router projects, Claude Code understands the file-based routing convention:

claude "Create the following page routes: /dashboard with a layout that includes a sidebar, /dashboard/analytics, /dashboard/settings, and /dashboard/settings/profile. Each page should have a proper loading.tsx and error.tsx boundary. Use the dashboard layout for all nested routes."

This generates the correct folder structure under src/app/dashboard/ with layouts, pages, loading states, and error boundaries, all following Next.js conventions.

Responsive Design Patterns

Claude Code handles responsive design well because Tailwind's breakpoint system is predictable. Provide the design intent and let it handle the breakpoints:

claude "Create a pricing card grid. Three cards side by side on desktop, stacked vertically on mobile. Each card has a plan name, price, feature list with checkmarks, and a CTA button. The middle card should be highlighted as 'Most Popular' with a larger scale and different border color."
💡

Tip: When iterating on frontend components, use Claude Code's interactive mode. Run claude without arguments to start a session, then describe changes conversationally: "Make the cards rounded-2xl instead" or "Add a subtle shadow on hover." This back-and-forth feels natural and moves fast.

Backend and API Development

The backend is where Claude Code really shines for productivity. Route definitions, middleware chains, validation schemas, error handling: these are repetitive patterns that Claude Code generates accurately and consistently.

Building Express Routes

claude "Create a REST API for a blog platform using Express with TypeScript. I need CRUD routes for posts and comments. Each route should go through authentication middleware. Use a controller pattern — routes in src/routes/, controllers in src/controllers/, and types in src/types/. Add proper error handling with a centralized error middleware."

Claude Code will generate structured files like:

// src/routes/posts.ts
import { Router } from 'express';
import { PostController } from '../controllers/postController';
import { authenticate } from '../middleware/auth';
import { validate } from '../middleware/validate';
import { createPostSchema, updatePostSchema } from '../schemas/postSchema';

const router = Router();
const postController = new PostController();

router.get('/', postController.getAll);
router.get('/:id', postController.getById);
router.post('/', authenticate, validate(createPostSchema), postController.create);
router.put('/:id', authenticate, validate(updatePostSchema), postController.update);
router.delete('/:id', authenticate, postController.delete);

export default router;

Middleware Development

Middleware is the backbone of any Express or Fastify app. Claude Code understands common patterns:

claude "Create the following middleware: (1) JWT authentication that extracts user from token and attaches to request, (2) role-based authorization that accepts an array of allowed roles, (3) request logging that logs method, path, status code, and response time, (4) rate limiting with 100 requests per 15 minutes per IP."

Input Validation

For validation, Zod has become the standard in TypeScript backends. Claude Code writes Zod schemas fluently:

claude "Create Zod validation schemas for the blog API. A post needs a title (3-200 chars), body (min 10 chars), tags (array of strings, max 5), and optional publishedAt date. A comment needs body (1-1000 chars) and a postId reference. Create a reusable validation middleware that uses these schemas."

The generated validation middleware catches malformed requests before they reach your controllers, returning structured error responses with field-level messages.

Error Handling

A proper error handling strategy prevents your API from leaking stack traces or returning inconsistent error shapes:

claude "Create a centralized error handling system. Define an AppError class that extends Error with statusCode and isOperational properties. Create an error middleware that catches all errors, logs them appropriately, and returns consistent JSON error responses. In production, hide internal error details. In development, include the stack trace."
⚠️

Warning: Always review the authentication and authorization code Claude Code generates. As we discuss in our security and enterprise workflows guide, AI-generated security logic should be treated as a draft. Check token verification, password hashing algorithms, and session management against current best practices before deploying to production.

Database Integration with Prisma

Setting up a database layer is one of the most tedious parts of full-stack development. Prisma makes it manageable, and Claude Code makes it fast. If you want to learn more about how we set up development environments for these projects, see our development environment setup guide.

Initial Prisma Setup

claude "Set up Prisma with PostgreSQL. Initialize the schema with models for User, Post, Comment, and Tag. Users have email, name, passwordHash, and role (ADMIN or USER). Posts belong to a User and can have many Tags through a many-to-many relation. Comments belong to both a Post and a User. Add createdAt and updatedAt timestamps to all models. Include proper indexes on email and foreign keys."

Claude Code generates the prisma/schema.prisma file, installs the Prisma packages, and creates the initial migration. The schema might look like:

model User {
  id           String   @id @default(cuid())
  email        String   @unique
  name         String
  passwordHash String
  role         Role     @default(USER)
  posts        Post[]
  comments     Comment[]
  createdAt    DateTime @default(now())
  updatedAt    DateTime @updatedAt

  @@index([email])
}

model Post {
  id          String   @id @default(cuid())
  title       String
  body        String
  published   Boolean  @default(false)
  author      User     @relation(fields: [authorId], references: [id])
  authorId    String
  comments    Comment[]
  tags        Tag[]
  publishedAt DateTime?
  createdAt   DateTime @default(now())
  updatedAt   DateTime @updatedAt

  @@index([authorId])
}

enum Role {
  ADMIN
  USER
}

Running Migrations

After reviewing the schema:

claude "Run the Prisma migration to create the database tables. Name the migration 'initial-schema'. Then generate the Prisma client."

Claude Code will execute npx prisma migrate dev --name initial-schema and npx prisma generate for you.

Seed Data

Realistic seed data makes development much smoother:

claude "Create a Prisma seed file at prisma/seed.ts. Generate 3 users (one admin, two regular), 10 blog posts with varied content, 5 tags, and 20 comments distributed across the posts. Use bcrypt for password hashing. Wire up the seed command in package.json."

CRUD Operations with Prisma

claude "Create a PostService class in src/services/postService.ts that wraps all Prisma operations for posts. Include methods for: findAll with pagination, filtering by tag, and sorting; findById with author and comments included; create; update (only if the user is the author); delete (soft delete by setting a deletedAt field); and a search method using full-text search on title and body."

This service pattern keeps your controllers thin and your database logic testable in isolation.

ℹ️

Info: When working with databases, always review the generated Prisma schema before running migrations. Check that relations, indexes, and constraints match your requirements. Migrations are difficult to undo cleanly, so getting the schema right on the first pass saves headaches later.

Testing Workflows

Testing is where many developers slack off. Claude Code makes it painless to write thorough tests because it understands your codebase and can generate tests that actually exercise real logic.

Unit Tests with Vitest

Vitest has become the go-to test runner for modern JavaScript and TypeScript projects. It is fast, compatible with Jest syntax, and works natively with Vite and TypeScript.

claude "Set up Vitest for this project. Configure it in vitest.config.ts with path aliases matching our tsconfig. Create unit tests for the PostService class — test each method with mocked Prisma client. Cover the happy path, edge cases (post not found, unauthorized update), and error conditions."

A generated test file might include:

import { describe, it, expect, vi, beforeEach } from 'vitest';
import { PostService } from '@/services/postService';
import { prismaMock } from '../__mocks__/prisma';

describe('PostService', () => {
  let postService: PostService;

  beforeEach(() => {
    postService = new PostService(prismaMock);
    vi.clearAllMocks();
  });

  describe('findById', () => {
    it('returns a post with author and comments', async () => {
      const mockPost = {
        id: 'post-1',
        title: 'Test Post',
        body: 'Content here',
        author: { id: 'user-1', name: 'Alice' },
        comments: [],
      };
      prismaMock.post.findUnique.mockResolvedValue(mockPost);

      const result = await postService.findById('post-1');

      expect(result).toEqual(mockPost);
      expect(prismaMock.post.findUnique).toHaveBeenCalledWith({
        where: { id: 'post-1' },
        include: { author: true, comments: true },
      });
    });

    it('returns null when post does not exist', async () => {
      prismaMock.post.findUnique.mockResolvedValue(null);

      const result = await postService.findById('nonexistent');

      expect(result).toBeNull();
    });
  });
});

Integration Tests

Integration tests verify that your API routes, middleware, and database work together. Claude Code can generate these using Supertest:

claude "Create integration tests for the posts API routes. Use Supertest with Express. Set up a test database using Prisma with a separate .env.test file. Before each test suite, seed the database. After each suite, clean up. Test creating a post (authenticated), fetching all posts with pagination, updating a post (only by author), and deleting a post."

End-to-End Tests with Playwright

For full e2e testing, Playwright covers all major browsers:

claude "Set up Playwright for end-to-end testing. Create tests for: (1) user can sign up and see dashboard, (2) user can create a new blog post, (3) posts appear on the public homepage, (4) user can edit their own post, (5) user cannot edit another user's post. Use Playwright's built-in test fixtures for authentication state."

Test-Driven Development

Claude Code works well with TDD if you frame your prompts that way:

claude "I want to add a search feature to the posts API. First, write the tests for a GET /api/posts/search endpoint that accepts a 'q' query parameter, searches post titles and bodies, supports pagination, and returns results sorted by relevance. Then implement the endpoint to make those tests pass."

This "tests first" approach produces cleaner code because Claude Code writes the implementation specifically to satisfy the test expectations.

💡

Tip: Run your tests frequently during development. You can tell Claude Code to run the test suite after making changes: claude "Run the tests and fix any failures." It will execute the tests, read the output, and patch the code until the suite passes.

Deployment and Production Readiness

Building locally is one thing. Shipping to production is another. Claude Code helps bridge that gap by generating the configuration files and scripts that deployment demands.

Environment Variables

claude "Create a typed environment variable configuration using zod. Define required variables for DATABASE_URL, JWT_SECRET, NODE_ENV, and CORS_ORIGIN. Optional variables for REDIS_URL and SMTP settings. Create a .env.example file with placeholder values. Add validation that runs at startup and fails fast with clear error messages if required variables are missing."

This gives you runtime validation instead of discovering missing environment variables in production at 2 AM.

Build Optimization

For Next.js projects:

claude "Optimize the Next.js build configuration. Enable standalone output mode for Docker deployment. Configure image optimization with a remote patterns allowlist. Set up bundle analysis. Add headers for caching static assets. Configure redirects for legacy URLs."

For Vite projects:

claude "Optimize the Vite build. Configure code splitting for routes. Set up gzip and brotli compression. Add a bundle size analyzer. Configure chunk naming for better caching."

Docker Configuration

claude "Create a multi-stage Dockerfile for the Next.js application. Stage 1: install dependencies. Stage 2: build the application. Stage 3: production image using node:20-alpine with only the standalone output. Include a .dockerignore file. Add a docker-compose.yml that runs the app alongside PostgreSQL and Redis with proper networking and volume persistence."

A well-structured Dockerfile keeps your production image small (often under 150MB for a Next.js app) while including only the files needed to run.

Deploying to Vercel

claude "Prepare this Next.js project for Vercel deployment. Create a vercel.json with proper configuration. Set up environment variables for production. Add a build script that runs migrations before the build. Configure preview deployments for pull requests."

Deploying to Railway

For full-stack apps that need a backend server and database:

claude "Create a Railway deployment configuration. Set up a Procfile for the Express backend. Configure the PostgreSQL addon. Add a release command that runs Prisma migrations. Set up health check endpoint at /health."

Production Checklist

Before deploying, ask Claude Code to audit your project:

claude "Review this project for production readiness. Check for: hardcoded secrets, missing error boundaries, unhandled promise rejections, missing CORS configuration, SQL injection vectors, missing rate limiting, proper logging setup, and health check endpoints. List every issue found."

In our experience at Luminous Digital Visions, this production audit prompt catches three to five issues on a typical project. It is not a substitute for a full security review, but it catches the common oversights. For production applications, consider our web development services or backend development for professional guidance.

⚠️

Warning: Never commit .env files to version control. Use .env.example for documenting required variables and let each environment (development, staging, production) maintain its own .env file. Claude Code respects .gitignore rules, but always double-check sensitive files are excluded.

Frequently Asked Questions

Can Claude Code scaffold projects in frameworks other than Next.js and Vite?

Yes. Claude Code can scaffold projects in virtually any framework — Remix, SvelteKit, Nuxt, Astro, Angular, and more. The prompting pattern is the same: specify the framework, language, styling, and directory structure you want. It also works for backend-only projects in Python (Django, FastAPI), Go, Rust, and other languages.

How does Claude Code handle large codebases during development?

Claude Code can handle substantial codebases by reading files on demand, searching your project using glob and grep patterns, and building an understanding of your architecture as it works. For very large projects, you can focus its attention by specifying which directories or files to work in.

Will Claude Code overwrite my existing code?

Claude Code always shows you what it plans to do before making changes. In interactive mode, it asks for confirmation before writing files. You can review diffs, approve specific changes, and reject others. That said, use version control. Commit frequently so you always have a rollback point.

What is the best way to handle database migrations in a team?

Use Prisma's migration workflow. Each developer runs npx prisma migrate dev locally, which creates migration files that get committed to version control. In CI/CD, run npx prisma migrate deploy which applies pending migrations without generating new ones. Claude Code can set up this entire workflow for you.

Can I use Claude Code with an existing project or only new ones?

Both. Claude Code reads and understands existing codebases. Navigate into your project directory and run claude. It will analyze your file structure, package.json, and existing code patterns. Then ask it to add features, refactor modules, or fix bugs. It will follow your existing conventions.

How do I handle environment variables across different deployment platforms?

Each platform has its own way of managing environment variables. Vercel uses the dashboard or vercel env CLI. Railway uses railway variables. Docker uses .env files or secrets. Claude Code can generate the correct configuration for any platform. Just specify where you are deploying.

Is it better to test with Jest or Vitest?

For new projects in 2026, Vitest is generally the better choice. It is faster, has native TypeScript and ESM support, and uses the same configuration as Vite. Jest still works perfectly well, especially in existing projects. Claude Code generates high-quality tests for either framework.

What if Claude Code generates code with bugs?

It happens. Claude Code is highly capable but not infallible. The best workflow is to write tests alongside your features. When Claude Code generates code, ask it to also generate tests. Run the tests immediately. If something fails, paste the error back into Claude Code and ask it to fix the issue. This feedback loop converges quickly.

How do I handle authentication in full-stack apps built with Claude Code?

Ask Claude Code to set up your preferred auth solution. It can implement JWT-based auth from scratch, integrate NextAuth.js (now Auth.js), or set up OAuth flows with providers like Google and GitHub. Specify which approach you want and it will generate the complete implementation including middleware, session management, and protected routes.

Can Claude Code help with database schema design?

Absolutely. Describe your domain model in plain language (the entities, their relationships, and the queries you need to support) and Claude Code will design the Prisma schema. It handles one-to-many, many-to-many, self-referential relations, and composite indexes. Review the schema carefully before running migrations.

Does Claude Code support monorepo setups with shared packages?

Yes. Claude Code works well with pnpm workspaces, Turborepo, Nx, and Lerna monorepos. You can ask it to scaffold a monorepo from scratch with shared TypeScript types between frontend and backend packages. It understands workspace dependency resolution and can run scripts scoped to specific packages. Just be explicit about which package you want it to modify when giving prompts.

Does Claude Code prefer TypeScript over JavaScript for new projects?

Claude Code generates whichever language you specify. If you do not specify, it tends to default to TypeScript because the majority of modern project templates and examples it has learned from use TypeScript. If you want JavaScript, say so explicitly in your prompt. Claude Code will generate JSDoc type annotations for JavaScript projects if you ask for them as an alternative to TypeScript.

How should I handle API keys and secrets in projects built with Claude Code?

Claude Code follows the standard practice of using environment variables via process.env. It generates .env.example files with placeholder values and adds .env to .gitignore. For typed environment access, ask Claude Code to create a Zod-based config module that validates all required variables at startup. Never accept generated code that hardcodes a secret. If you see one, flag it immediately and ask Claude Code to move it to an environment variable.

Can Claude Code manage database migration workflows beyond the initial setup?

Yes. Claude Code handles the full Prisma migration lifecycle. You can ask it to add columns, create new models, set up relations, or rename fields, and it will modify the schema and run npx prisma migrate dev to generate the migration file. For production, it knows to use npx prisma migrate deploy. It can also generate data migration scripts for backfilling data when schema changes require it.

Does hot reloading work when Claude Code edits files during development?

Yes. If you have a development server running with hot module replacement (Vite, Next.js dev, or webpack-dev-server), changes that Claude Code makes to your source files trigger hot reloads exactly as if you edited the files by hand. Your browser updates automatically. This makes the iterative workflow fast. Ask Claude Code for a change and see it reflected in the browser within seconds.

Can Claude Code generate CI/CD pipeline configurations?

Absolutely. Describe your build, test, and deploy pipeline and Claude Code generates the configuration file. It supports GitHub Actions, GitLab CI/CD, CircleCI, and other providers. A typical prompt might be: "Create a GitHub Actions workflow that runs linting, unit tests, and integration tests on every PR, and deploys to Vercel on merge to main." Claude Code produces a working YAML file with proper job dependencies, caching, and secrets references.

How do I get Claude Code to set up Docker Compose for local development?

Ask it directly. Something like: "Create a docker-compose.yml with the Next.js app, a PostgreSQL database, and a Redis instance for caching. Include volume mounts for persistent database storage, a healthcheck for Postgres, and proper networking so the app can reach both services." Claude Code generates the compose file, a Dockerfile with multi-stage builds, and a .dockerignore file. It can also add a Makefile or npm scripts for common Docker commands.

Can Claude Code set up environment-specific configurations?

Yes. Claude Code can generate configuration modules that load different settings based on NODE_ENV or a custom environment variable. It handles patterns like separate database URLs for development, staging, and production. You can ask it to create a config factory that validates and merges default, shared, and environment-specific settings using Zod, dotenv, or similar tools.

Does Claude Code support GraphQL API development?

Yes. Claude Code can scaffold a full GraphQL API using Apollo Server, GraphQL Yoga, or other libraries. It generates type definitions (SDL or code-first with TypeGraphQL), resolvers, data loaders for N+1 query prevention, and context setup for authentication. On the client side, it generates typed queries and mutations using GraphQL Code Generator or similar tools.

Can Claude Code help implement WebSocket features?

Yes. Claude Code generates WebSocket implementations using Socket.io, the native ws library, or frameworks with built-in WebSocket support. It handles server setup, event handlers, room management, authentication for WebSocket connections, and client-side connection management with reconnection logic. For Next.js projects, it can set up a separate WebSocket server or use a third-party service.

How should I handle file uploads in a project built with Claude Code?

Ask Claude Code to generate the upload handling code for your specific needs. It can set up Multer middleware for Express, create presigned URL flows for S3 or R2 uploads, or implement chunked upload handling for large files. It generates proper validation for file type, size limits, and content checking. Just specify your storage target (local filesystem, S3, Cloudflare R2, etc.) and any constraints.

Can Claude Code suggest caching strategies for my application?

Yes. Describe your application's data access patterns and Claude Code will recommend and implement appropriate caching. It can set up Redis caching with TTL-based expiration, implement in-memory caching with LRU eviction, configure HTTP cache headers for static assets, set up Next.js ISR (Incremental Static Regeneration) for dynamic pages, and generate cache invalidation logic. Specify your traffic patterns and data freshness requirements for the best results.

How do I use Claude Code to set up error monitoring and logging?

Ask Claude Code to integrate your preferred monitoring service. It can set up Sentry for error tracking with proper source maps, configure structured logging with Pino or Winston, create custom error classes with metadata, and wire up error boundaries in React. A good prompt would be: "Set up Sentry error monitoring for both the Next.js frontend and Express backend. Include source map uploads in the build step and add a global error boundary component."

What performance optimization prompts work best with Claude Code?

Be specific about what you want to optimize. Instead of "make it faster," try: "Analyze the dashboard page for performance issues. Check for unnecessary re-renders, missing React.memo on list items, unoptimized images, large bundle imports that should be code-split, and database queries that could benefit from indexes or eager loading." Claude Code will audit the specified area and implement concrete optimizations with explanations for each change.
