bruvtools Project Analysis

🎯 Project Purpose

bruvtools is a Universal Cloud Deployment CLI designed to deploy microservices to multiple cloud providers (CapRover, AWS, GCP, Kubernetes) using the same simple commands. The core philosophy is "Deploy anywhere, any language, one CLI" with zero vendor lock-in.

🏗️ Key Components

1. CLI Entry Point (bin/bruvtools.js)

• Purpose: Main executable that users run
• Features:
  • Error handling for uncaught exceptions
  • Environment variable loading via dotenv
  • Delegates to the main CLI class

2. Core CLI System (lib/core/cli.js)

• Size: 656 lines - the heart of the application
• Key Features:
  • Interactive Setup: bruvtools init with guided prompts
  • Provider Management: Dynamic loading of cloud providers
  • Command Registration: All CLI commands (deploy, create, scale, etc.)
  • CapRover CLI Validation: Checks if CapRover CLI is installed
  • Configuration Generation: Auto-creates bruvtools.yml and .env files

3. Configuration Management (lib/core/config.js)

• Purpose: Handles configuration merging and persistence
• Features:
  • Multi-level config: Project → Global → Default
  • YAML-based: Uses bruvtools.yml for configuration
  • Provider-specific settings: Supports multiple cloud providers
  • Project isolation: Each project can have its own settings

4. Provider Architecture (lib/providers/)

• Base Provider (base.js): Abstract class defining the interface
  • Core operations: deploy, create, delete, scale, restart
  • Environment management: setEnv, getEnv
  • Monitoring: logs, status, test
  • Service management: list, services
• CapRover Provider (caprover/index.js): Currently the only implemented provider
  • Wraps the battle-tested capgen.js functionality
  • Provides all base provider methods
  • Handles CapRover-specific configuration

5. CapRover Integration (lib/providers/caprover/capgen.js)

• Size: 716 lines of comprehensive CapRover CLI wrapper
• Features:
  • Commands: login, list, create, configure, deploy, package
  • Windows Compatibility: Handles PowerShell and cmd differences
  • Environment Validation: Checks required variables
  • API Integration: Direct CapRover API calls for advanced operations
  • Deployment Pipeline: Complete packaging and deployment workflow

🚀 Core Functionality

Interactive Setup (bruvtools init)

1. Provider Selection: Choose cloud provider (CapRover recommended)
2. Credential Collection: Machine name, domain, password (masked)
3. Project Configuration: Name, port selection (80, 3000, 8080, 5000, custom)
4. Environment Variables: Optional additional env vars
5. File Generation: Creates bruvtools.yml and .env automatically
6. CLI Validation: Checks if CapRover CLI is installed

Deployment Commands

• bruvtools create <app-name>: Create app on cloud provider
• bruvtools deploy <app-name>: Deploy application
• bruvtools scale <app-name> <replicas>: Scale application
• bruvtools restart <app-name>: Restart application
• bruvtools delete <app-name>: Delete application

Management Commands

• bruvtools services: Dashboard showing all deployed services
• bruvtools logs <app-name>: View application logs
• bruvtools status <app-name>: Check application status
• bruvtools test <app-name>: Test application endpoint

🛠️ Technology Stack

Dependencies

• commander: CLI framework for command parsing
• inquirer: Interactive prompts for setup
• chalk: Terminal colors and formatting
• yaml: Configuration file parsing
• dotenv: Environment variable management

Supported Languages

• Node.js (auto-detected via package.json)
• Go (auto-detected via go.mod)
• Python (auto-detected via requirements.txt)
• Java (auto-detected via pom.xml, build.gradle)
• PHP (auto-detected via composer.json)
• Ruby (auto-detected via Gemfile)
• Any containerizable app (via Dockerfile)

📦 Example Application

The examples/hello-world/ directory contains a working Node.js application:

• server.js: Simple HTTP server responding with "🎉 HELLO FROM BRUVTOOLS - ACTUALLY WORKING!"
• package.json: Minimal Node.js configuration
• captain-definition: CapRover deployment configuration (Node.js 18.18.2 template)

🌐 Current State & Version

• Version: 0.2.9 (published to npm)
• Status: Production-ready for CapRover deployments
• Live Example: cnpj-enricher.bruvbot.com.br (Go API)
• Test Example: final-hello.bruvbot.com.br (Node.js)

🎯 Key Strengths

1. Universal Interface: Same commands work across different cloud providers
2. Zero Vendor Lock-in: Easy to switch between providers
3. Interactive Setup: User-friendly configuration process
4. Language Agnostic: Supports any containerizable application
5. Production Ready: Battle-tested with real deployments
6. Comprehensive Documentation: 468-line README with real-world examples
7. Windows Support: Fixed PowerShell compatibility in v0.2.9

🔮 Future Roadmap

The architecture is designed for expansion:

• AWS Provider: Planned implementation
• GCP Provider: Planned implementation
• Kubernetes Provider: Planned implementation
• Railway Provider: Planned implementation

The modular provider system makes adding new cloud platforms straightforward by extending the BaseProvider class.

This project represents a mature, production-ready CLI tool that successfully abstracts cloud deployment complexity while maintaining flexibility and avoiding vendor lock-in.
