Key Learnings from Building a Successful Elixir Application at VO

Fernando and Vicente provide an in-depth look at their experiences and lessons learned while developing an Elixir application at VO, a meta-search engine for hotel accommodations. The presentation covers various architectural and coding strategies that helped them overcome challenges and optimize their application. Key topics include the use of dependency injection with Mox and Mimic libraries, implementing the Saga pattern with the Sage library for handling complex transactions, improving logging practices with Metal Logger, and establishing standardized testing conventions. They also delve into their methods for environment-specific and request-specific configuration management, ensuring robust validation and casting using Ecto. The authors share their collective learning, aiming to spark discussions and offer valuable insights for others working with Elixir.
