The fastest reliable route is to start with the official Next.js documentation and Learn tutorials, choose an example that matches your router and feature, then initialize it with create-next-app --example. Treat every repository as a starting point: inspect its version, scripts, dependencies, environment variables and license before adapting it.
Where to look first
Use the official Next.js documentation as your map. Its material is divided between App Router and Pages Router documentation, with guides, API references and use-case tutorials. App Router is the newer routing system; Pages Router is the original system and remains supported. The official Learn courses include starter projects hosted on GitHub and show the setup commands rather than asking you to assemble a project from unrelated snippets.
GitHub search is useful when you need a narrowly focused example, but search results are not a quality guarantee. A repository can be obsolete, incomplete, differently licensed or written for a framework version unlike yours. Prefer an official example when it demonstrates the behavior you are learning, then use third-party repositories only after checking their documentation and history.
Search GitHub without losing the important context
Use targeted searches
Search for the feature and router together instead of searching only for “Next.js example.” Useful patterns include nextjs app router authentication, nextjs pages router api route, or a GitHub code search for a distinctive file such as app/page.tsx or pages/index.tsx. Add a language qualifier when appropriate, such as TypeScript.

Open the repository, not just a code result
Read the README, then inspect the root directory, package.json, lockfile, configuration files and any .env.example. Look for the exact command used to install and run the project. A lockfile normally indicates the intended package manager: for example, pnpm-lock.yaml, yarn.lock or package-lock.json. Do not copy secrets from an .env file into source control.
Check suitability before copying code
- Confirm that the example covers the feature you need, not merely a similar visual layout.
- Match its Next.js and React versions to the project you will extend.
- Check required services, environment variables and database or authentication providers.
- Read the license and inspect recent changes, open issues, dependencies and security advisories before treating it as a production foundation.
- Keep deployment requirements in mind; a server-dependent example may not work as a static export.
Tell whether a repository uses App Router or Pages Router
App Router clues
An App Router project normally has an app directory. Routes are represented by directories containing special files such as page and layout. The root layout is required and includes the document-level html and body elements. You may also see route groups, loading or error files and server-component conventions.
Pages Router clues
A Pages Router project defines routes from files under a pages directory. For example, pages/index.tsx maps to the home page and pages/api contains API routes. Files such as _app and _document are characteristic of this system.
Do not infer the router from one folder alone
A repository can contain both directories during a migration, and a component library may contain neither. Read the README and inspect the actual route used by the example. Compare the implementation with the current App Router or Pages Router documentation before moving files between systems; data fetching, layouts and server/client boundaries differ.

Start an official or public GitHub example
Use the CLI’s example option
create-next-app accepts an official example name or a public GitHub repository URL. The general pnpm form is:
pnpm create next-app --example [example-name] [your-project-name]For a public repository, pass its URL. The CLI reference also documents --example-path for selecting a path inside a repository, --skip-install to create files without installing dependencies, and --disable-git to avoid initializing a Git repository. Confirm the current reference before relying on a flag because CLI behavior can change.
Pages Router Learn starter
This official tutorial command creates a local project from the Learn starter:
npx create-next-app@latest nextjs-blog --use-npm --example "https://github.com/vercel/next-learn/tree/main/basics/learn-starter"Replace nextjs-blog with your directory name if needed. The URL points to a path within the public vercel/next-learn repository, so the command illustrates how a repository subdirectory can be used as an example source.

The App Router dashboard tutorial likewise uses the vercel/next-learn repository and a dashboard starter path. Use the command shown by the current tutorial rather than assuming that an old path still exists. Tutorial repositories can be reorganized even when the underlying concept is unchanged.
Run the project and make a controlled change
- Clone or initialize. Either run
create-next-app --exampleor clone the repository as its README instructs. If you clone, change into the project directory. - Install with the intended manager. Use the package manager indicated by the lockfile and README. Avoid mixing managers, which can produce a different dependency tree.
- Configure environment variables. Copy an example environment file if supplied, create local values and keep credentials out of Git. If a service such as a database is required, start it before launching the app.
- Start development. Run the documented development script, commonly
npm run dev,pnpm devoryarn dev. Open the local URL printed by the command. - Verify the advertised route. Visit the route demonstrated by the tutorial, exercise its form or API call and watch the terminal for build errors.
- Change one thing. Edit a visible string or style, save, and confirm hot reload. Then trace the route to the component, data function and asset that control it.
- Preserve a baseline. Commit the untouched starter or keep a separate branch before larger changes, so you can compare behavior and recover quickly.
Understand the layout before adapting it
Official dashboard material is a useful orientation model: route and application code may live in app, reusable server or data utilities in app/lib, visual components in app/ui, static files in public, and project behavior in configuration files. This is an example structure, not a rule that every repository follows.
Start at the route you need, then follow imports outward. Identify whether a component runs on the server or client, where data is fetched, which CSS system is configured and how assets are resolved. Read scripts in package.json before replacing them; a custom script may set required environment variables or generate code.
Choose between examples with a repeatable checklist
| Axis | What to compare | Why it matters |
|---|---|---|
| Router | App Router, Pages Router or a migration containing both | Routing, layouts, data fetching and component boundaries differ. |
| Feature match | The exact routing, data, styling or deployment behavior demonstrated | A visually similar demo may omit the mechanism you need. |
| Setup | Package manager, scripts, services, environment variables and configuration | Hidden prerequisites are a common cause of failed starts. |
| Compatibility | Next.js, React, Node.js and dependency versions | APIs and defaults change across releases. |
| Maintenance and risk | License, commits, issues, dependency health and advisories | Popularity alone does not establish safety or production readiness. |
| Deployment | Node.js server, Docker, static export or an adapter | Static export supports fewer server-dependent features. |
Deployment choices can change what the example supports
The official deployment guidance lists Node.js server deployment, Docker, static export and platform adapters. Node.js and Docker deployments support all Next.js features according to that guidance. Static export has limited feature support, so an example that depends on server rendering, API routes or other server behavior may need a different deployment model. The same documentation identifies Vercel and Bun as verified adapters and lists other integrations with varying support; check the current deployment page for platform-specific details.
Troubleshoot common failures
The example URL fails
Check that the repository is public, the path is still present and the URL points to the intended subdirectory. If the project moved, clone the repository and follow its current README, or choose a maintained official starter.
Dependencies install but the build fails
Use the lockfile’s package manager, verify the required Node.js version, remove an incompatible existing install and reinstall. Then compare the example’s Next.js version with the API documentation for the code you changed.
The page is blank or a route returns 404
Confirm that you are visiting the route represented by the file you edited. In App Router, a route needs the appropriate page file; in Pages Router, it must be under pages. Check the terminal for compilation errors and verify that you started the development script from the project root.
Environment or service errors appear
Find every referenced variable in the source and README, create the expected local environment file and restart the server after changing it. Verify that external services are running and that values use the required format. Never publish credentials.
Static deployment drops functionality
Compare the example’s server requirements with static export’s limited support. Use a Node.js or Docker deployment when the feature requires a server, or refactor the example to a client-only/static-compatible design.
Or skip the browser setup
If your goal is to document an example, generate preview images or capture a running Next.js page, ScreenshotNeo provides a single website screenshot API call instead of managing browser automation. It accepts a URL and returns PNG, JPEG, WebP or PDF. Before capture it accepts cookie or consent banners and removes more than 60 known consent platforms, newsletter popups and chat widgets; each cleanup step can be disabled. Only clean shots are billed: bot checks, CAPTCHAs, blank pages, timeouts, failed loads and cache hits cost nothing, and the response identifies the page verdict and billing status in X-Page-Verdict and X-Billed headers.
Use the API details at https://screenshotneo.com/docs/. Replace the target URL in these runnable examples:
curl -G "https://api.screenshotneo.com/v1/shot" -d access_key=YOUR_API_KEY --data-urlencode url=https://stripe.com -o shot.webpimport requests
r = requests.get("https://api.screenshotneo.com/v1/shot", params={"access_key": "YOUR_API_KEY", "url": "https://stripe.com"}, timeout=90)
open("shot.webp", "wb").write(r.content)const q = new URLSearchParams({ access_key: 'YOUR_API_KEY', url: 'https://stripe.com' });
const res = await fetch(`https://api.screenshotneo.com/v1/shot?${q}`);ScreenshotNeo also supports full-page and element captures, device presets and custom viewports, retina scale, dark mode, PDF options, custom CSS and JavaScript, clicks, waits, blocked resources, headers, cookies, user agents, authorization, timezone, geolocation, transparent backgrounds, resizing, chosen cache TTLs, signed links, asynchronous webhooks, bulk capture of up to 100 URLs per call, a usage API and an OpenAPI specification. Its MCP server exposes take_screenshot, get_page_info and capture_pdf for Claude, Cursor and other MCP clients. Parameter names used by other screenshot APIs also work.
The Free plan includes 1,000 screenshots per month with no card. Paid plans start at $5 for 3,000 shots; every feature is on every plan, and yearly billing gives two months free. Create a free ScreenshotNeo account to get started.
Frequently asked questions
Can I use a private GitHub repository with --example?
The documented example flow is for official examples or public GitHub repository URLs. For private code, use your organization’s authenticated clone and follow its local setup instructions.
Should a beginner start with App Router?
Choose the router used by the tutorial or application you plan to extend. App Router exposes newer React features, while Pages Router remains supported; switching systems mid-tutorial adds concepts unrelated to the feature you are trying to learn.
Is an example automatically production-ready?
No. Treat it as instructional code until you have reviewed its license, dependencies, security posture, error handling, observability, performance and deployment requirements.
