• What's the source of truth?
• Teach the Elm compiler about external things like schemas
• elm-graphql
• dillonkearns/elm-graphql
• Types Without Borders
• Macros in other languages
• C macros compared to Lisp macros
• ReScript ppx macros
• Vanilla code generation can be inspected and debugged like plain handwritten code
• Gitignore gen code so you know you didn't forget to generate it on the build server

Watchers for rerunning codegen* Rerun code gen when the source of truth changes ideally * Chokidar CLI * The Design of Everyday Things by Donald Norman * Affordances * Mappings * elm-tailwind-modules * Chadtech/elm-vector * the-sett/salix * elm-ts-interop

Scaffolding* elm-review init, new-rule, and new-package * elm-spa new * html-to-elm.com * End to end testing your generated code * Snapshot testing * elm-graphql's snapshot testing script * html-to-elm.com generated test suite * elm-verify-examples
