HttpValidationResponseMapping

@ng-forge/dynamic-forms

Mapping configuration for interpreting HTTP responses as validation results.

Expressions in validWhen and errorParams are evaluated with scope { response } only — they do NOT have access to formValue, fieldValue, or the full EvaluationContext. This is intentional for v1: response mapping is purely about interpreting the HTTP response.

interface HttpValidationResponseMapping

Properties

Name	Type	Description
`validWhen`	`string`	Expression evaluated with scope `{ response }`. Must evaluate to `true` (strict boolean) to be valid. NOTE: This is the OPPOSITE of the function-based HttpCustomValidator.onSuccess convention, which maps successful HTTP responses to validation errors. Here, `=== true` means "validation passed". Non-boolean results are treated as invalid and trigger a warning.
`errorKind`	`string`	Error kind returned when validation fails — maps to field-level `validationMessages`
`errorParams` ?	`Record<string, string>`	Parameters to include in the validation error for message interpolation. Map of parameter names to expressions evaluated against `{ response }`.
