Auto-Generating AWS Services from Smithy Models
Introduction AWS provides over 200 services, each with its own API protocol and request/response structure. Manually implementing them one by one is practically impossible. At DevCloud, we built a codegen pipeline that reverse-engineers AWS’s internal modeling language, Smithy, to auto-generate Go code for nearly all AWS services. This post covers the full flow from parsing Smithy models to generating Go code, and how the auto-generated code powers a local AWS emulator. But the more fundamental question is: why generate code from an IDL at all? To understand the value beyond simple “productivity automation,” we need to first understand the problem this approach solves. ...
