Elixir Tutorials

Elixir: Getting Started with Functional Programming

Learn Elixir: functional programming on the BEAM VM, pattern matching, pipe operator, immutability, Mix build tool, and the Phoenix web framework. Step-by-step with examples.

Elixir Data Types — Integers, Floats, Atoms, Tuples, Lists, Maps

Learn Elixir's built-in data types: integers, floats, atoms, booleans, strings, tuples, lists, maps, and how pattern matching works with each type.

Elixir Pattern Matching — The Pin Operator, Guards, and Match Expressions

Master Elixir's pattern matching: pin operator for rebinding, guards for validation, match expressions in function heads, case/cond/with constructs.

Elixir Control Flow — if, unless, cond, case, and with

Learn control flow in Elixir: if/unless for branching, cond for multi-condition checks, case for pattern matching switch, and with for pipelined pattern matches.

Elixir Functions — Named Functions, Anonymous Functions, and Captures

Learn Elixir functions: named functions with def/defp, anonymous functions with fn, the capture operator &, arity, default arguments, and function composition.

Elixir Enum and Stream — Lazy and Eager Collection Operations

Master Elixir's Enum module for eager collection operations and Stream for lazy evaluation. Map, filter, reduce, and infinite streams.

Elixir Pipe Operator — Data Transformation Pipelines

Master Elixir's pipe operator (|>) for building readable data transformation pipelines. Forward-piping, function capturing, and pipeline patterns.

Elixir Modules and Structs — Organization and Data with Types

Learn Elixir modules for code organization and structs for typed data. Module attributes, use/import/require, struct validation, and @type annotations.

Elixir OTP — GenServer, Supervisor, and Application

Learn Elixir's OTP (Open Telecom Platform): GenServer for stateful servers, supervision trees for fault tolerance, and Application for system startup.

Elixir Testing — ExUnit, Doctests, and Mocking

Learn testing in Elixir with ExUnit: writing test cases, assertions, doctests in documentation, setup callbacks, and test organization.

Elixir Concurrency — spawn, send, receive, and Tasks

Learn Elixir's concurrency model: spawning processes, message passing with send/receive, Tasks for fire-and-forget work, and process linking.

Elixir Phoenix Framework — Controllers, Views, LiveView and Routing

Learn the Phoenix web framework: routing, controllers, views, templates, LiveView for real-time UI, and Ecto for database access.

Elixir Ecto — Database Queries, Schemas, Migrations, and Repos

Learn Ecto for database access in Elixir: schemas for data mapping, migrations for schema changes, queries with Ecto.Query, and Repo operations.

Elixir Error Handling — try, rescue, with, and Tagged Tuples

Learn Elixir error handling: try/rescue for exceptions, tagged tuples for expected failures, the with construct for pipelined error handling, and OTP supervision.

Elixir Mix Build Tool — Projects, Tasks, Dependencies, and Configuration

Learn Elixir's Mix build tool: creating projects, custom mix tasks, dependency management, environment config, and umbrella projects.
