bloom_validate library

Declarative, strictly-typed request body and DTO validation for Bloom applications.

Provides zero-codegen validation for HTTP request bodies, query params, and JSON payloads with fail-fast error accumulation, built-in validation rules, and direct conversion of validation errors into standard HTTP 400 Bad Request responses.

Example:

import 'package:bloom_server/bloom_server.dart';
import 'package:bloom_validate/bloom_validate.dart';

class SignupRequestSchema extends BloomRequestSchema {
  SignupRequestSchema(super.data);
  SignupRequestSchema.fromRequest(super.request) : super.fromRequest();

  late final String name = requireStringLength('name', min: 2, max: 50, description: 'Full name');
  late final String email = requireEmail('email', description: 'User email address');
  late final String password = requireStringLength('password', min: 8, max: 128, description: 'Account password');
  late final String? referralCode = optionalString('referralCode');

  @override
  void validate() {
    name;
    email;
    password;
    referralCode;
  }
}

Future<BloomResponse> handleSignup(BloomRequest request) async {
  try {
    final schema = BloomRequestSchema.validateSchema(SignupRequestSchema.fromRequest(request));
    return BloomResponse.json({
      'message': 'User registered successfully',
      'email': schema.email,
      'name': schema.name,
    }, statusCode: 201);
  } on BloomValidationException catch (e) {
    return e.toResponse();
  }
}
