Quick Start

The best way to start with this template is using Create Next App.

# pnpm
pnpm create next-app -e https://github.com/castrogusttavo/nextjs-boilerplate

# yarn
yarn create next-app -e https://github.com/castrogusttavo/nextjs-boilerplate

# npm
npx create-next-app -e https://github.com/castrogusttavo/nextjs-boilerplate

Development

To start the project locally, run:

pnpm dev

Open http://localhost:3000 with your browser to see the result.

Documentation

Requirements

• Node.js >= 20
• pnpm >= 9

Directory Structure

• .github - GitHub configuration including the CI workflows.
  
• .husky - Husky configuration and hooks.
  
• public - Static assets such as robots.txt, images, and favicon.
  
• app - Application source code.
  

Tasks (Scripts)

• pnpm dev — Starts the application in development mode at http://localhost:3000.
• pnpm build — Creates an optimized production build of your application.
• pnpm start — Starts the application in production mode.
• pnpm lint — Runs Biome for all files in the app directory.
• pnpm format — Runs Biome for fix all files in the app directory .
• pnpm format:check — Checks all files in the app directory for correct formatting.

Path Mapping

This boilerplate uses the @ prefix to import components or images. This is configured in the tsconfig.json file.

import { Button } from '@/components/Button';
// To import images or other files from the public folder
import avatar from '@/public/avatar.png';

Switch to Yarn/npm

This starter uses Deno by default, but this choice is yours. If you'd like to switch to Yarn/npm, delete the deno.lock file, install the dependencies with Yarn/npm, change the CI workflow, and Husky Git hooks to use Yarn/npm commands.

Note: If you use Yarn, make sure to follow these steps from the Husky documentation so that Git hooks do not fail with Yarn on Windows.

Environment Variables

We use Dot Env to manage environment variables. Create a .env.local file in the root of the project and add your environment variables there.

When adding additional environment variables, the schema in ./app/lib/env/client.ts or ./app/lib/env/server.ts should be updated accordingly.

Redirects

To add redirects, update the redirects array in ./redirects.ts. It's typed, so you'll get autocompletion for the properties.

CSP (Content Security Policy)

The Content Security Policy (CSP) is a security layer that helps to detect and mitigate certain types of attacks, including Cross-Site Scripting (XSS) and data injection attacks. The CSP is implemented in the next.config.ts file.

It contains a default and minimal policy that you can customize to fit your application needs. It's a foundation to build upon.
