Docker Setup

Prerequisites

• Docker
• Docker Compose

Development with Docker

1. Set up environment variables:

   cp .env.example .env

   Edit .env with your configuration.

2. Start the development environment:

   docker compose up dev

   This will:

   • Build the development image using Node.js 22 Alpine
   • Mount your local codebase for hot-reloading
   • Make the app available at http://localhost:4321

3. Development Features:

   • Hot-reloading enabled
   • Source code mounted from host
   • Node modules cached in Docker volume
   • Full access to development tools
   • Network access from other devices via host IP

Production with Docker

1. Build and run the production environment:

   docker compose up prod

   This will:

   • Build an optimized production image
   • Run the application in production mode
   • Enable automatic restarts unless stopped
   • Make the app available at http://localhost:4321

2. Manual production deployment:

   # Build the production image
   docker build -t datum-website --target production .
   
   # Run the production container
   docker run -p 4321:4321 \
     -e NODE_ENV=production \
     -e SITE_URL=your-site-url \
     datum-website

Docker Configuration Details

The setup uses a multi-stage Dockerfile:

1. Base stage (node:22-alpine)

   • Minimal Alpine Linux with Node.js 22
   • Common workspace setup

2. Development stage

   • Full development dependencies
   • Source code mounting
   • Hot-reload enabled
   • Development-specific configurations

3. Production stage

   • Multi-stage build for optimization
   • Only production dependencies
   • Pre-built assets
   • Minimal final image size

Network Configuration

• Host: 0.0.0.0 (allows external access)
• Port: 4321 (configurable via environment)
• Docker network: datum-network (bridge mode)
• Volume mounts (development):
  • .:/src: Source code
  • /app/node_modules: Dependencies

Troubleshooting

1. If the development server isn't accessible:

   # Rebuild the development image
   docker compose up dev --build

2. To view logs:

   # Development logs
   docker compose logs dev
   
   # Production logs
   docker compose logs prod

3. To clean up:

   # Stop and remove containers
   docker compose down
   
   # Remove volumes too
   docker compose down -v

🧞 Commands

All commands are run from the root of the project, from a terminal:

Command	Action
npm install	Installs dependencies
npm run dev	Starts local dev server at localhost:4321
npm run build	Build your production site to ./dist/
npm run preview	Preview your build locally, before deploying
npm run astro ...	Run CLI commands like astro add, astro check
npm run astro -- --help	Get help using the Astro CLI
npm run lint	Check for linting and formatting issues
npm run lint:fix	Automatically fix linting and formatting issues
npm run lint:md	Check for markdown linting issues
npm run lint:md:fix	Automatically fix markdown linting issues
npm run format	Format all files using Prettier
npm run format:check	Check if files are formatted correctly
npm run typecheck	Astro typescript check
npm run precommit	Run all checks (typecheck, lint, format) before commit

Code Quality

This project uses ESLint with Prettier integration for code quality and formatting:

• ESLint: For code linting and enforcing code style rules
• Prettier: Integrated with ESLint for code formatting
• TypeScript: For type checking and enhanced IDE support
• Markdownlint: For markdown and MDX file linting

The configuration supports:

• TypeScript (.ts, .tsx)
• JavaScript (.js, .jsx)
• Astro (.astro)
• Markdown (.md)
• MDX (.mdx)
• JSON (.json)

Markdown Linting

The project uses markdownlint-cli to ensure consistent markdown formatting across all content files. The linting is specifically configured for MDX files with React components in the /src/content/ directory.

Configuration

The markdownlint configuration (.markdownlint.json) is optimized for MDX and React components:

• Disables line length limits (MD013)
• Allows inline HTML/JSX (MD033)
• Flexible heading structure (MD024, MD025, MD026)
• Supports component-based content (MD036, MD040)
• Allows dynamic content (MD042, MD047)
• Flexible list formatting (MD029, MD031, MD032)

Usage

To check markdown files:

npm run lint:md

To automatically fix markdown issues:

npm run lint:md:fix

The linter will only check files in the /src/content/ directory, including:

• Blog posts
• Documentation
• Guides
• Changelog entries
• Static pages

VS Code Setup

For the best development experience, install the following VS Code extensions:

1. ESLint
2. Prettier
3. Markdownlint

The project includes VS Code settings (.vscode/settings.json) that enable:

• Live linting and error detection
• Format on save
• Automatic ESLint fixes on save
• Proper formatting for Astro, TypeScript, JavaScript, and Markdown files
• TypeScript SDK integration

Ignore Files

The project includes configuration files to ignore certain files and directories:

• .prettierignore: Specifies files and directories to be ignored by Prettier
• .eslintignore: Specifies files and directories to be ignored by ESLint

These files ignore:

• Build output (dist/, .astro/)
• Dependencies (node_modules/)
• Generated files (*.generated.*, *.min.*)
• Log files
• Environment files (except .env.example)
• Editor directories and files
• Package manager files
• Public assets
