DX CLI

A CLI tool for managing DevEx (Developer Experience) guidelines and best practices 🚀

📖 Overview

The DX CLI is a command-line tool designed to help developers manage and validate their development setup according to PagoPA's DevEx guidelines. It provides automated checks and validations to ensure repositories follow the established best practices and conventions.

✨ Features

• Repository Validation: Verify repository setup against DevEx guidelines with the doctor command
• Code Migrations: Apply automated migration scripts (codemods) to update code and configurations
• Project Initialization: Bootstrap new monorepo projects with standardized structure
• Cost Optimization: Analyze Azure subscriptions to identify unused or underutilized resources
• Project Information: Display comprehensive information about your project setup and tools
• Developer Experience Optimization: Ensure consistent development practices across projects

🚀 Installation

Install the CLI globally using your preferred package manager:

# Using npm
npm install -g @pagopa/dx-cli

# Using yarn
yarn global add @pagopa/dx-cli

# Using pnpm
pnpm add -g @pagopa/dx-cli

From Source (Development)

# Clone the repository
git clone https://github.com/pagopa/dx.git
cd dx

# Install dependencies (using npm)
npm install

# Or using yarn
yarn install

# Or using pnpm
pnpm install

# Build the CLI
npm run build
# Or: yarn build
# Or: pnpm build

# Run the CLI
node ./apps/cli/bin/index.js --help

🛠️ Usage

Available Commands

doctor

Verify the repository setup according to the DevEx guidelines.

dx doctor

This command will:

• Check if you're in a valid Git repository
• Validate that required monorepo scripts are present in package.json
• Check that the turbo.json file exists
• Verify that the installed turbo version meets the minimum requirements

Example output:

$ dx doctor
Checking monorepo scripts...
✅ Monorepo scripts are correctly set up

codemod

Manage and apply migration scripts (codemods) to the repository.

# List available codemods
dx codemod list

# Apply a specific codemod by ID
dx codemod apply <id>

This command helps you:

• View all available migration scripts for your repository
• Apply automated code transformations to keep your codebase up to date
• Migrate configurations and code patterns to newer standards

init

Bootstrap a new monorepo project with standardized structure and remote repository provisioning.

dx init project

This command will:

• Check that required tools (e.g., Terraform CLI) are installed
• Interactively prompt for project metadata (cloud provider, region, environments, cost center, etc.)
• Check that the target GitHub repository does not already exist before proceeding
• Generate a monorepo structure following PagoPA DevEx guidelines
• Create a remote GitHub repository using Terraform
• Push the initial codebase to the newly created repository

If the specified GitHub repository already exists, the command will fail early with a clear error message, preventing accidental overwrites.

Example usage:

$ dx init project
? What is the repository name? my-monorepo
? What is the GitHub repository owner? pagopa
? What is the repository description? My new PagoPA monorepo
...

✔ Terraform CLI is installed!
✔ Workspace files created successfully!
✔ GitHub repository created successfully!
✔ Code pushed to GitHub successfully!

Workspace created successfully!
- Name: my-monorepo
- Cloud Service Provider: azure
- CSP location: italynorth
- GitHub Repository: https://github.com/pagopa/my-monorepo

Note

The command will fail early if required tools are missing.

info

Display comprehensive information about your project setup and tools.

dx info

This command provides:

• Current project configuration details
• Installed tool versions
• Repository metadata
• Development environment information

savemoney

Analyze Azure subscriptions to identify unused or underutilized resources that could be costing you money.

dx savemoney [options]

Options:

Option	Alias	Description	Default
--config	-c	Path to a YAML configuration file.	N/A
--format	-f	Report format: table, json, detailed-json, or lint.	table
--days	-d	Metric analysis period in days (overrides config file).	30
--location	-l	Preferred Azure location for resources (overrides config file).	italynorth
--verbose	-v	Enable verbose mode with detailed logging for each resource analyzed.	false
--tags	-t	Filter resources by tags (key=value key2=value2). Only resources matching all specified tags are analyzed (variadic: space-separated).	N/A

Example usage:

# Analyze with default settings (interactive prompts)
dx savemoney

# Use a configuration file
dx savemoney --config config.yaml

# Output as JSON with verbose logging
dx savemoney --format json --verbose

# Linter-style output for CI pipelines
dx savemoney --config config.yaml --format lint

# Analyze only resources tagged environment=prod
dx savemoney --config config.yaml --tags "environment=prod"

# Analyze with specific timespan
dx savemoney --days 60 --location italynorth

Configuration file example (config.yaml):

azure:
  subscriptionIds:
    - subscription-1
    - subscription-2
  preferredLocation: italynorth
  timespanDays: 30
  thresholds: # optional — omit to use built-in defaults
    vm:
      cpuPercent: 5
    appService:
      cpuPercent: 10
      memoryPercent: 20
    storage:
      transactionsPerDay: 50

Analyzed Azure resources:

• Virtual Machines: Deallocated or stopped VMs, low CPU usage
• Managed Disks: Unattached disks
• Network Interfaces: Unattached NICs
• Public IP Addresses: Unassociated static IPs
• Storage Accounts: Low transaction counts
• App Service Plans: Empty plans or oversized tiers
• Private Endpoints: Unused or misconfigured endpoints
• Container Apps: Not running, zero replicas, low resource usage
• Static Web Apps: No traffic or very low usage patterns

Note

Currently only Azure is supported. Support for additional cloud providers (AWS) is planned for future releases.

Global Options

• --version, -V: Display version number
• --help, -h: Display help information
