Exploring Python Integration in Elixir Applications

In a discussion hosted by Charles Suggs, Victor Björklund explores how to effectively integrate Python into Elixir applications. The conversation covers multiple integration methods such as HTTP APIs, ports, ErlPort, and the Venomous library, analyzing the performance and coupling trade-offs associated with each. Real-world examples, including web scraping with Scrapy and using the Swedish BankID for authentication, are used to highlight best practices for error handling, process pooling, and telemetry when crossing the BEAM boundary. The duo also addresses deployment strategies including packaging Python dependencies within Mix releases, testing mixed-language systems, and ensuring smooth deployment of multi-language applications. Victor shares his vision for future improvements in interop, such as managing multiple Python interpreters within a single VM, and suggests accessible starting points for teams interested in harnessing Python’s capabilities alongside Elixir.
