djb 0.2.21

Django + Bun deployment platform

djb - Django + Bun Platform

djb is a deployment platform for Django applications with modern frontend tooling (Bun). It provides utilities for secrets management, deployment, and development workflows.

Architecture

djb is organized as a Python package within the beachresort25 project:

djb/
├── __init__.py          # Package initialization
├── secrets/             # Encrypted secrets management
│   ├── __init__.py      # Public API exports
│   └── core.py          # Encryption/decryption implementation
└── cli/                 # Command-line interface
    ├── __init__.py
    ├── djb.py           # Main CLI entry point
    ├── init.py          # Environment initialization
    ├── secrets.py       # Secrets management
    └── deploy.py        # Heroku deployment

Features

Initialization

One-command setup for development environment:

# Full initialization
djb init

# Initialize with options
djb init --skip-brew          # Skip Homebrew dependencies
djb init --skip-frontend      # Skip frontend setup
djb init --skip-secrets       # Skip secrets initialization
djb init --project-root /path # Specify project directory

This installs:

• System dependencies via Homebrew (age, PostgreSQL, GDAL, Bun)
• Python dependencies (uv sync)
• Frontend dependencies (bun install)
• Encrypted secrets management

Secrets Management

Age-style encrypted secrets for secure configuration:

# Initialize secrets
djb secrets init

# Edit environment secrets
djb secrets edit dev
djb secrets edit production

# View secrets
djb secrets view dev
djb secrets list

Documentation: See docs/SECRETS_GUIDE.md

Deployment

Heroku deployment with frontend builds, secrets sync, and migrations:

# Deploy to Heroku (uses DJB_APP_NAME from Django settings)
djb deploy heroku

# Or specify app explicitly
djb deploy heroku --app myapp

# Deploy with options
djb deploy heroku --skip-build --skip-secrets

# Revert to previous deployment
djb deploy revert

# Revert to specific commit
djb deploy revert abc1234

App Name Auto-Detection: If DJB_APP_NAME is set in your Django settings, deployment commands will use it automatically. You can still override with --app.

# In settings.py
DJB_APP_NAME = "myapp"

Usage

Command Line

djb provides two CLI interfaces:

1. Direct: djb <command>
2. Via beachresort: br <command> (convenience wrapper)

Both are equivalent. The beachresort CLI delegates to djb internally.

Python API

Import djb modules directly in Python code:

from djb.secrets import load_secrets, AgeKey, SecretsManager

# Load secrets for current environment
secrets = load_secrets()
api_key = secrets['api_keys']['stripe']

# Encrypt/decrypt programmatically
key = AgeKey.generate()
manager = SecretsManager(secrets_dir=Path('secrets'), age_key=key)
manager.save_secrets('dev', data, [key.to_public_string()], encrypt=True)

Installation

djb is included in the beachresort25 project. After cloning:

# One-command setup (installs all dependencies)
djb init

# Or install manually
uv sync

# Verify djb is available
djb --help

Development

Adding New Commands

1. Create a new subcommand module in djb/cli/
2. Define your Click command group
3. Register it in djb/cli/djb.py:

from djb.cli.mycommand import mycommand

djb_cli.add_command(mycommand)

Adding New Features

1. Implement the feature in an appropriate module under djb/
2. Export public API in djb/__init__.py if needed
3. Add CLI commands if applicable
4. Update documentation

Architecture Decisions

Why djb is in beachresort25

djb started as a separate project but has been integrated into beachresort25 to:

1. Simplify dependency management
2. Allow rapid iteration on both the platform and application
3. Enable project-specific customization
4. Avoid version conflicts between djb and application dependencies

The original external djb project will be deprecated in favor of this integrated approach.

Why Age Encryption

• Modern cryptography: X25519 + ChaCha20-Poly1305
• Simple key management: Single key file vs PGP keyring complexity
• Git-safe: Encrypted values can be committed
• Future-proof: Compatible with Kubernetes sealed secrets

Future Plans

Planned djb features:

• Environment initialization - djb init
• Deployment commands (Heroku) - djb deploy heroku, djb deploy revert
• App name auto-detection from Django settings (DJB_APP_NAME)
• Git hooks setup via djb init (pre-commit hook for editable djb check)
• Deployment commands (Kubernetes)
• Development server management
• Database migration utilities
• Multi-recipient secret encryption
• Secret rotation automation
• Environment variable syncing
