Elixir and DGraph: Building Graph Database Projects with dlex

Managing complex, highly connected data structures requires a database designed specifically for relationships. Combining Elixir's concurrent power with DGraph's native graph database capabilities provides a robust solution for modern application backends. In this text-based course, you will learn how to integrate Elixir with DGraph using the native dlex gRPC client. You will transition from understanding core graph database concepts to writing efficient queries and mutations directly from your Elixir codebase. What you'll learn: Understand foundational graph database concepts and how DGraph structures nodes and edges; Configure and set up an Elixir project with the dlex gRPC client dependency; Define schemas and map Elixir structs to DGraph types; Execute mutations to insert, update, and delete graph data; Query connected data efficiently using GraphQL+- syntax through Elixir; Apply modern Elixir practices such as robust error handling and supervisor-managed database connections. This course begins with basic graph theory and configuration setup before guiding you through practical, step-by-step code implementations of mutations and queries. Designed for Elixir developers who want to explore graph databases, this course assumes basic familiarity with Elixir but requires no prior experience with DGraph. Start reading today to unlock the power of graph databases in your next Elixir project.
