What You’ll Learn
Elixir’s Origins and Philosophy: Trace Elixir’s evolution from its Erlang/BEAM roots to its modern role in building scalable, fault-tolerant, real-time systems. Discover the motivations behind its creation, the influence of functional programming, and the thriving open-source community that drives its adoption.
Functional Programming Foundations: Grasp the core tenets of Elixir’s functional style—immutability, pattern matching, recursion, and the expressive pipe operator. Learn how these features enable clear, maintainable, and reliable code, even in complex systems.
Concurrency and Reliability on the BEAM: Demystify how Elixir leverages the BEAM virtual machine to support millions of lightweight processes, message passing, and preemptive scheduling. Understand the “let it crash” philosophy, supervision strategies, and the building blocks of resilient, concurrent applications.
OTP and System Architecture: Dive into OTP’s essential abstractions—GenServer, Supervisor, Agent, Task, and Application. See how these components compose into robust supervision trees and self-healing architectures, and learn best practices for error handling, shutdown, and observability.
Metaprogramming and Abstractions: Explore Elixir’s powerful metaprogramming capabilities, including macros, protocols, and the abstract syntax tree (AST). Learn how these tools enable elegant domain-specific languages and extensible APIs, while understanding the trade-offs and best practices for maintainability.
Web Development at Warp Speed: Get an overview of the modern Elixir web stack—Phoenix, LiveView, Ecto, Channels, and PubSub. Discover how Elixir enables fast, real-time, and SEO-friendly web applications with minimal client-side complexity.
Data Pipelines and Integrations: Understand how Elixir connects to databases, streams and processes events, and integrates with message brokers like Kafka and RabbitMQ. Learn about GenStage, Flow, and Broadway for building reliable, high-throughput, event-driven pipelines.
Embedded Systems with Nerves: See how Elixir powers IoT and edge devices using the Nerves framework, bringing BEAM reliability to embedded hardware, and learn about deployment, updates, and security in resource-constrained environments.
Tooling, Testing, and Deployment: Master the Elixir ecosystem’s tools for project management, testing, formatting, static analysis, releases, and observability. Gain insights into CI/CD, performance testing, and production readiness.
Industry Use Cases and Best Practices: Map Elixir to high-impact domains like real-time chat, fintech, e-commerce, streaming, gaming, and telecom. Explore architectural patterns, performance characteristics, and common pitfalls to avoid, while looking ahead at community trends and the future of the BEAM. In this course, I'll be explaining simple concepts of coding in Elixir. You'll learn all the basics: printing to screen, creating variables, getting using input, doing simple math, conditionals, lists, enums, etc. This is a simple steady-paced course that can be effective for anyone who has an interest in coding in Elixir. You could be someone with experience in another language or someone entirely new to coding.
In section 11-14 I'll be teaching the basic syntax of Elixir using an online IDE, called replit, which serves its purpose great. However, replit has become some kind of ai app builder since I created these sections of the course so I remmend using any other online editor to follow along with these sections like onecompiler.
"Elixir" is used by many companies, for example, Adobe, Discord, Moz, and the Financial Times. It has many applications, and in this course, we'll be sticking to the basics.
I will be explaining code snippets and there will be a link to the repl that I'm discussing in the lecture resources. You can then fork it, and change the names and arguments in the code to come up with additional examples for each concept. Or you can use copy/paste.
This course is a beginner-friendly breeze and will allow anyone to effectively grasp the core concepts of Elixir in just a short amount of time.
