Standalone validation

@data-driven-forms/react-form-renderer/validation

(schema: Schema, options: Options) => object: Errors

Data Driven Forms provides an async function that validates values based on a provided schema. This feature can be useful to implement validation on backend endpoints with using the same schema as in frontend applications.

Schema

object

The same schema as for the form renderer. Validation supports all features except array validators that are being used by field arrays. This functionallity will be implemented in the future.

Options

object

{
  values: AnyObject;
  componentMapper?: ComponentMapper;
  validatorMapper?: ValidatorMapper;
  actionMapper?: ActionMapper;
  schemaValidatorMapper?: SchemaValidatorMapper;
  omitWarnings?: boolean;
}

Values

object

Form values as sent from the renderer.

componentMapper

object

If not provided, all components are valid. Read more.

validatorMapper

actionMapper

schemaValidatorMapper

omitWarnings

boolean

If this attribute set to true, warnings will be ignored and won't appear in the errors object.

Errors

object

A flat structure of errors.

{
  field: 'This field is required',
  'field-with-warning': { type: 'warning', error: 'This is warning' },
  'nested.field': 'Some error message'
}

Schemas changed according to meta

If your form is changing according to form state or field states, be aware that this function will miss all meta information.
