🏢 Enterprise Patterns

Welcome to the Enterprise Patterns tutorial! In this course, you'll learn how to use ECC to build scalable, maintainable large-scale project architectures — like building a skyscraper, the foundation determines the height.

Prerequisites

It's recommended to complete all intermediate tutorials, especially Multi-Agent Workflows and Custom Hooks.

🎮 Try Enterprise-Level Commands

ECC provides specialized governance and architecture tools for large projects. Try these commands:

Pillar 1: Monorepo Architecture

A Monorepo keeps multiple related projects in one repository. Like a large shopping mall — different stores (apps) share infrastructure (electricity, parking), operate independently but are managed together. Turborepo is the most popular Monorepo tool in the JavaScript ecosystem.

💡Turborepo's remote cache can speed up CI builds by 10x!

💻 Design Your Monorepo Architecture

Design a complete enterprise-level Monorepo configuration in the code playground:

Turborepo Configurationjson

{ "$schema": "https://turbo.build/schema.json", "globalDependencies": [ "**/.env.*local" ], "pipeline": { "build": { "dependsOn": ["^build"], "outputs": ["dist/**", ".next/**", "!.next/cache/**"] }, "dev": { "cache": false, "persistent": true }, "test": { "dependsOn": ["build"], "outputs": ["coverage/**"], "inputs": ["src/**/*.tsx", "src/**/*.ts", "test/**/*.ts"] }, "test:e2e": { "dependsOn": ["build"], "outputs": ["playwright-report/**"] }, "lint": { "dependsOn": ["^build"], "outputs": [] }, "typecheck": { "dependsOn": ["^build"], "outputs": [] }, "clean": { "cache": false } }, "globalEnv": [ "NODE_ENV", "CI" ], "remoteCache": { "enabled": true } }
