195: Migrating from Next.js to Phoenix
Thinking Elixir Podcast
Improving Test Performance with Process Dictionary and Process Tree Library in Elixir
Explore how utilizing the process dictionary over application environment variables can enhance test performance in Elixir. Learn about the process tree library for navigating the Elixir process hierarchy and gain insights on maintaining a balance between test-specific code and production code.
In this compelling episode, we sit down with Ben Reinhart who shares his journey of transitioning from the JavaScript ecosystem, specifically migrating off of Next.js and Vercel, to Elixir and Phoenix, with Fly.io as the new host. Ben discusses his frustrations with the complexity and performance issues he faced, and how the switch to Elixir helped streamline operations and improve the efficiency of his AI-focused product at Axflow. He delves into his strategic choice for leveraging the operational simplicity and real-time features of Phoenix, while also acknowledging trade-offs such as rebuilding front-end components. Join us to explore Ben's story, learn about the features of Elixir that helped him, and discover how the move has influenced Axflow's path towards finding product-market fit, and more!
