Elixir is a relatively new framework but shows rapid growth due to its flexibility as a functional, concurrent, distributed programming language.

This course is a practical guide to adopting an Elixir-based technology stack for distributed web applications. Engineering managers will find helpful guides on upskilling and cross-skilling their teams, and technical leads will grasp the meaningful differences between Elixir and traditional stacks. The course moves from high-level concepts such as staffing, code management, and legacy systems to developing your Elixir environment with a walkthrough of making the functional transition, distributed Elixir, and integrating external code. You’ll wrap up with deployment and maintenance functions, assessing performance, and finalizing the application.

By the end of this course, engineering managers will be prepared to tackle the unique challenge of migrating web applications to Elixir.

Adopting Elixir for Software Engineering Leads & Managers

Code linters focus on code layout concerns such as indentation.

Code linters focus on code quality and code structure such as functions and variable names.

Code linters focus on code compilation errors.
