Hello World

This tutorial introduces EMB fundamentals using a minimal project - a single API service with just two files.

What You’ll Learn

1. Installation - Getting EMB up and running
2. Minimal Configuration - The simplest possible .emb.yml
3. Auto-Discovery - How EMB finds your components
4. First Commands - Essential EMB commands

The Example Project

We’ll use examples/hello-world, the simplest possible EMB project:

hello-world/
├── .emb.yml          # Just 6 lines of config
└── api/
    ├── Dockerfile    # Standard Node.js image
    ├── package.json
    └── server.js     # Simple Express API

This example demonstrates that EMB can work with minimal configuration - you don’t need to define every component explicitly.

Prerequisites

Before starting, ensure you have:

• Node.js 20+ installed
• Docker installed and running

Let’s Begin

Continue to Installation to set up EMB on your system.
