Overview ¶
Package formrules parses validation tags and checks submitted form values against them. kit uses it at run time; codegen uses it to write the same rules for the browser, where packages/tern/src/runtime/validate.ts applies them with the same messages. testdata/cases.json keeps the two in step.
