🎯 What is Leeforge CLI?

Leeforge CLI is a powerful command-line tool that helps you:

• Initialize new Leeforge Fusion projects with templates
• Develop with hot module replacement
• Build optimized production bundles
• Generate code scaffolding for pages, APIs, and components
• Manage your project configuration

🚀 Installation

npm install -g @leeforge/fusion-cli

Or use with npx:

npx @leeforge/fusion-cli <command>

Binary Names:

• leeforge-fusion (primary)
• lf-fusion (alias)

Usage:

# Using primary binary
leeforge-fusion dev

# Using alias
lf-fusion dev

📖 Usage Guide

Leeforge CLI provides a comprehensive set of commands to streamline your development workflow.

1. Initialize Project

Create a new Leeforge Fusion project with a template:

# Create a new project with the basic template
leeforge init my-app

# Create a project with a specific template
leeforge init my-blog --template blog
leeforge init my-dashboard --template dashboard

# Available templates:
# - basic: Simple app with home and about pages
# - blog: Blog with posts, categories, and RSS
# - dashboard: Admin dashboard with authentication

Template Comparison:

| Template | Features | Best For | | ------------- | ------------------------------------ | --------------------- | | basic | Home page, About page, Basic routing | Learning, Simple apps | | blog | Posts, Categories, RSS feed, Search | Content websites | | dashboard | Authentication, Admin panel, Charts | Business applications |

2. Development Server

Start the development server with hot module replacement:

# Start on default port (3000)
leeforge dev

# Start on custom port
leeforge dev --port 3001

3. Build for Production

Create an optimized production build:

# Standard build
leeforge build

# Build with custom output directory
leeforge build --outDir dist

# Build with source maps
leeforge build --sourcemap

# Build for specific environment
leeforge build --mode production

Build Output:

• Optimized JavaScript bundles
• Static HTML files
• CSS extraction
• Asset optimization
• Type definitions

4. Code Generation

Generate code scaffolding to speed up development:

# Generate a page
leeforge generate page blog/[id]

# Generate an API route
leeforge generate api users/[id]

📋 Available Commands

init

Initialize a new Leeforge Fusion project.

Syntax:

leeforge-fusion init [name] [options]

Arguments:

• name: Project name (default: "my-app")

Options:

• -t, --template <type>: Template to use (basic, blog, dashboard) (default: "basic")

leeforge-fusion init my-blog --template blog

# Dashboard template
leeforge-fusion init my-dashboard --template dashboard

Options:

• --template <name>: Use a specific template (basic, blog, dashboard)
• --git: Initialize git repository
• --install: Install dependencies automatically
• --pm <manager>: Package manager (npm, yarn, pnpm)

Examples:

📁 Project Structure

After running leeforge-fusion init, your project will have:

my-app/
├── src/
│   ├── app/
│   │   ├── layout.tsx          # Root layout
│   │   ├── index.tsx           # Home page
│   │   ├── about.tsx           # About page
│   │   └── blog/
│   │       ├── index.tsx       # Blog list
│   │       └── [id].tsx        # Dynamic blog post
│   └── middleware/
│       └── auth.ts             # Authentication middleware
├── leeforge.config.ts          # Configuration
├── package.json
└── tsconfig.json

After running leeforge-fusion generate, your project will have:

my-app/
├── app/
│   ├── blog/[id]/
│   │   └── index.tsx           # Generated page
│   └── api/users/[id]/
│       └── route.ts            # Generated API
├── components/
│   └── Button/
│       └── Button.tsx          # Generated component
└── ...

🔧 Configuration

The CLI automatically creates leeforge.config.ts in your project root:

import { defineConfig } from "@leeforge/fusion";

export default defineConfig({
  api: {
    prefix: "/api",
  },
  vite: {
    server: {
      port: 3000,
    },
  },
});

Configuration Options

API Configuration:

• prefix: API route prefix (default: "/api")
• timeout: Request timeout in milliseconds

Vite Configuration:

• server.port: Development server port (default: 3000)
• server.host: Host address
• build.outDir: Build output directory
• build.sourcemap: Generate source maps
• Any Vite configuration option is supported

Route Guards:

• guards: Object mapping routes to middleware files
• Example: "/admin/*": "./src/middleware/auth.ts"

How Configuration Works

1. Loading: CLI loads leeforge.config.ts from project root
2. Merging: Configuration is merged with framework defaults
3. Usage: Used by dev and build commands
4. Optional: If no config exists, defaults are used

Command Implementation

init Command:

• Loads templates from inline code (not external files)
• Creates directory structure
• Writes template files
• Supports 3 templates: basic, blog, dashboard

dev Command:

• Imports @leeforge/fusion dynamically
• Loads configuration from leeforge.config.ts
• Detects app directory automatically
• Starts Vite dev server

build Command:

• Uses Vite's build API
• Builds client and server bundles
• Code splitting for vendor chunks
• Outputs to dist/ directory

generate Command:

• Dynamic import of generators
• Supports: page, api, component
• Creates files in appropriate directories
• Supports dry-run mode

Template System

Templates are defined inline in commands/init.ts:

const templates = {
  basic: {
    /* basic template files */
  },
  blog: {
    /* blog template files */
  },
  dashboard: {
    /* dashboard template files */
  },
};

Template Files Include:

• src/app/layout.tsx
• src/app/index.tsx
• src/app/about.tsx (basic)
• leeforge.config.ts
• package.json
• tsconfig.json

📊 CLI Features

Dynamic Imports

Commands are loaded dynamically to improve startup time:

// Only loads when command is executed
const { devCommand } = await import("./commands/dev");

Dry Run Mode

Preview code generation without creating files:

leeforge-fusion generate page blog/[id] --dry-run
# Shows what files would be created

Automatic Directory Detection

The dev command automatically detects your app directory:

Search Order:

1. src/app
2. app
3. src
4. Current directory

Detection Logic:

• Looks for index.tsx, index.ts, page.tsx, page.ts, layout.tsx, or layout.ts
• Uses the first directory with page files found

Help System

Get help for any command:

leeforge-fusion --help
leeforge-fusion init --help
leeforge-fusion generate --help

Error Handling

• ✅ Graceful error messages
• ✅ Process exit codes
• ✅ Helpful suggestions
• ✅ File existence checks

🚀 Performance

Startup Performance

• Dynamic Imports: Commands loaded on-demand
• Fast Startup: <100ms CLI startup time
• Lazy Loading: Only loads required modules

Command Performance

• Init: ~2-3 seconds to create project
• Dev: Instant startup, HMR <100ms
• Build: ~2-3 seconds for small apps
• Generate: <50ms per generated file

Optimization Features

• Code Splitting: Vendor chunks in build
• Tree Shaking: Unused code elimination
• Dynamic Imports: On-demand module loading
• Fast Refresh: Vite HMR integration

🔍 Troubleshooting

Common Issues

Issue: Command not found

# Solution: Install globally or use npx
npm install -g @leeforge/fusion-cli
# or
npx @leeforge/fusion-cli <command>

Issue: Port already in use

# Solution: Use different port
leeforge-fusion dev --port 3001

Issue: Template not found

# Solution: Check available templates
leeforge-fusion init --help
# or use default template
leeforge-fusion init my-app

Issue: Generation fails

# Solution: Use dry-run to debug
leeforge-fusion generate page test --dry-run

Issue: Dev server won't start

# Solution: Check if leeforge.config.ts exists
# Create one if missing:
cat > leeforge.config.ts << 'EOF'
import { defineConfig } from "@leeforge/fusion";

export default defineConfig({
  api: {
    prefix: "/api",
  },
  vite: {
    server: {
      port: 3000,
    },
  },
});
EOF

Issue: Build fails

# Solution: Ensure src/app directory exists with page files
# Check structure:
ls -la src/app/
# Should have: layout.tsx, index.tsx, or page.tsx
