The article discusses the importance of avoiding repetitive tasks in software development and introduces a solution for customizing Phoenix's mix task generators to align with project requirements. The author emphasizes the balance between readability and avoiding boilerplate code offered by Elixir and Phoenix. While Phoenix's built-in generators are useful, they may not perfectly match the style and functionality of every project. To address this, the article suggests modifying and extending Phoenix's mix task generators. The example provided focuses on integrating Oban, a background job queue library, into the mix phx.new generator for non-umbrella apps. The article provides step-by-step instructions on how to make a copy of the installer folder, create a new mix phx.new task, and make the necessary changes to customize the generator. It also highlights the importance of considering the effort and maintenance required for maintaining custom mix tasks. This solution offers developers the flexibility to adapt Phoenix's generators to their specific project requirements.
