In this episode, Nicolas, a staff software engineer at Apollo GraphQL, discusses the company's use of GraphQL API technologies. Apollo GraphQL specializes in open-source libraries for both client and server-side applications, with a focus on integrating Rust into their main offerings: the Apollo router and GraphOS cloud. Nicolas explains how the Apollo router consolidates multiple microservices into a single API, efficiently routing requests to appropriate services.He delves into GraphQL's role as an effective query language for APIs, highlighting its ability to provide a comprehensive description of API data and its compatibility with existing data systems. The shift from the JavaScript-based Apollo Gateway to the Rust-based Apollo Router is a key topic, with an emphasis on the performance and safety improvements Rust brings to the table.The conversation covers the use of Rust for the router and GraphQL parser, alongside Kotlin for the management plane and GraphQL for the API. Challenges in stability and reliability are discussed, as well as Rust's advantages in safety and type system consistency. Nicolas shares insights on Async Rust, particularly its impact on productivity and application in CLI tools like Rover.The episode also addresses learning Rust in stages, from basic language concepts to advanced internal mechanisms. It touches on functional patterns in Rust and strategies for effective dependency management. Closing the discussion, Nicolas highlights the inclusive and supportive nature of the Rust community.
