A presentation given by Cailin Smith, Senior Software Engineer at Microsoft, at our 2024 Platform Summit, October 8-9. TypeSpec is a relatively new open source schema language coming out of Azure. In this talk, I will introduce you to the basics of using TypeSpec, and how apps.methodscript.com uses a Schema-First API design, allowing for developers to skip writing glue code, while maintaining a gigantic client support matrix, minimizing bugs, and speeding up API development.
