Next Episode: Learning a Language: Elixir vs. JavaScript with Yohana Tesfazgi & Wes Bos

In today’s episode, Sundi and Owen are joined by Yordis Prieto and Stephen Chudleigh to compare notes on HTTP requests in Elixir vs. Ruby, JavaScript, Go, and Rust. They cover common pain points when working with APIs, best practices, and lessons that can be learned from other programming languages.
Yordis maintains Elixir's popular Tesla HTTP client library and shares insights from building APIs and maintaining open-source projects. Stephen has experience with Rails and JavaScript, and now works primarily in Elixir. They offer perspectives on testing HTTP requests and working with different libraries.
While Elixir has matured, there is room for improvement - especially around richer struct parsing from HTTP responses. The discussion highlights ongoing efforts to improve the developer experience for HTTP clients in Elixir and other ecosystems.
Topics Discussed in this Episode
HTTP is a protocol - but each language has different implementation methods
Tesla represents requests as middleware that can be modified before sending
Testing HTTP requests can be a challenge due to dependence on outside systems
GraphQL, OpenAPI, and JSON API provide clear request/response formats
Elixir could improve richer parsing from HTTP into structs
Focus on contribution ergonomics lowers barriers for new participants
Maintainers emphasize making contributions easy via templates and clear documentation
APIs drive adoption of standards for client/server contracts
They discuss GraphQL, JSON API, OpenAPI schemas, and other standards that provide clear request/response formats
TypeScript brings types to APIs and helps to validate responses
Yordis notes that Go and Rust make requests simple via tags for mapping JSON to structs
Language collaboration shares strengths from different ecosystems and inspires new libraries and tools for improving the programming experience
