204: OTP 27 and Blend for Lib Maintainers

56 minutes

In this episode of the Thinking Elixir podcast, we sit down with Marcelo Dominguez, the driver behind the new "Blend" library, which assists Elixir library developers in testing their projects against multiple versions of dependencies. Marcelo explains the genesis of Blend and the inspiration from the Rubygem "appraisal." He discusses how Blend tackles the common headache of dependency version clashes and integrates smoothly with CI systems to isolate and report specific compatibility issues. We learn how it works under-the-hood and helps library maintainers more easily keep their promises of supporting a library used in diverse environments. We cover the motivations, complexities, and real-world applications of Blend and more!
