ModCLI

ModCLI is a command-line interface tool for the Modular framework that helps you scaffold and generate code for modular applications.

Installation

Using Go Install (Recommended)

Install the latest version directly using Go:

go install github.com/GoCodeAlone/modular/cmd/modcli@latest

After installation, the modcli command will be available in your PATH.

From Source

git clone https://github.com/GoCodeAlone/modular.git
cd modular/cmd/modcli
go install

From Releases

Download the latest release for your platform from the releases page.

Commands

ModCLI provides several commands to help you build modular applications:

Generate Module

Create a new module for your modular application with the following command:

modcli generate module --name MyModule --output ./modules

This will create a new module in the specified output directory with the given name. The command will prompt you for module features including:

• Configuration support
• Tenant awareness
• Module dependencies
• Startup and shutdown logic
• Service provisioning
• Test generation

For configuration-enabled modules, you can define configuration fields, types, and validation requirements.

Generate Config

Create a new configuration structure with:

modcli generate config --name AppConfig --output ./config

This command helps you define configuration structures with proper validation, default values, and serialization formats (YAML, JSON, TOML, etc.).

Examples

Creating a Basic Module

# Generate a basic module with minimal features
modcli generate module --name Basic --output .

Creating a Full-Featured Module

# Generate a module with all features enabled
modcli generate module --name FullFeatured --output .

When prompted, select all features (configuration, tenant awareness, etc.)

Creating a Configuration-Only Module

# Generate a module that focuses on configuration
modcli generate module --name ConfigOnly --output .

When prompted, select configuration support but disable other features.

Generated Files

For Modules

The generate module command creates the following files:

• module.go - Main module implementation
• config.go - Configuration structure (if enabled)
• config-sample.yaml/json/toml - Sample configuration files (if enabled)
• module_test.go - Test file with test cases for your module
• mock_test.go - Mock implementations for testing
• README.md - Documentation for your module
• go.mod - Go module file

For Config

The generate config command creates:

• config.go - Configuration structure with validation
• config-sample.yaml/json/toml - Sample configuration files

Development

ModCLI is built using the cobra command framework and generates code using Go templates.

Project Structure

• main.go - Entry point
• cmd/ - Command implementations
  • root.go - Root command
  • generate_module.go - Module generation logic
  • generate_config.go - Config generation logic

Running Tests
