This is a companion "app" for my talk at RubyConf 2026. While it does what it's supposed to, it's just a proof of concept(s). As such, please don't treat any of this as production-ready; it's intentionally weird and both over- and under-engineered.
To get the tools working properly, note that I'm defaulting to running on port 3001 rather than 3000. You can either just update that in the code directly, or you should be able to set SWAGGER_TOOLS_API_BASE_URL to http://localhost:3000 or whatever other URL you'd like.
