Why we chose Node.js over Python for our product

Launching a new product involves experimentation and adaptation, as demonstrated by Omer Rosenbaum's journey with Swimm, a web application initially built using Vue for the frontend and Python for the backend. Despite Python's popularity and Rosenbaum's personal affinity for the language, the transition to using Node.js for the CLI was necessary due to compatibility issues with different client environments and operating systems, which PyInstaller could not adequately address. This shift not only streamlined the technology stack by consolidating it under JavaScript, but also facilitated easier onboarding and collaboration among the development team. Although Rosenbaum still appreciates Python for its strengths, the practical challenges encountered highlighted the need for flexibility and the benefits of a unified codebase, leading to plans for future adoption of TypeScript.
