Building Graphs in Elixir Using Built-In Digraph Support

Representing complex networks of connected data—such as social connections, routing paths, or dependency trees—is a fundamental challenge in software development. Fortunately, Elixir comes with powerful, built-in support for graph data structures right out of the box through its native runtime integration. This written course guides you through the core concepts of graph theory and shows you how to implement them practically using the native digraph module. You will transition from understanding basic vertices and edges to writing clean, functional code that queries paths, handles cycles, and models real-world relationships in the interactive shell (IEx). By reading through structured explanations and analyzing practical code examples, you will gain a firm grasp of how to manage graph state efficiently. What you'll learn: - Understand foundational graph theory concepts, including vertices, edges, and directed versus undirected graphs. - Initialize and manage directed graphs in Elixir using the native Erlang digraph module. - Add, modify, and delete vertices and edges dynamically within the interactive shell. - Query graphs to find paths, determine connectivity, and detect cycles using built-in algorithms. - Apply modern Elixir pattern matching to handle graph query results safely. - Understand how the underlying ETS architecture manages graph state and mutability behind the scenes. You will start with essential definitions before moving on to hands-on console exercises. Through clear text explanations and structured code snippets, you will learn to construct a sample graph step-by-step, querying its relationships and analyzing its paths. This course is designed for beginner-to-intermediate Elixir developers who want to understand graphs without relying on heavy external dependencies. No prior experience with graph theory is required.
