Acanthis

Acanthis is a Validation library heavily inspired by Zod. It is designed to be a simple, and easy to use validation library.

Features

Acanthis is designed to be composable. Schemas can be composed together to create more complex schemas.

Also Acanthis doesn't require any runtime dependencies, and makes use of a chainable API to create schemas.

Getting Started

To get started with Acanthis, you can install it using the following command:

dart pub add acanthis

Example

Here is a simple example of how to use Acanthis:

import 'package:acanthis/acanthis.dart';

void main() {
  final schema = object({
	'name': string().min(3),
	'age': number().positive(),
  });

  final result = schema.tryParse({
	  'name': 'Francesco',
	  'age': 59,
  });

  /// The result is a AcanthisParseResult object
  /// that has the following properties:
  /// - success: A boolean that indicates if the parsing was successful or not.
  /// - value: The value of the parsing. If the parsing was successful, this will contain the parsed value.
  /// - errors: The errors of the parsing. If the parsing was unsuccessful, this will contain the errors of the parsing.

  if (result.success) {
	  print('The schema is valid!');
  } else {
	  print('The schema is invalid!');
  }
}

As you can see if you come from a Zod background, the API is very similar and should be familiar to you.
