Async Validator
async-validator est une bibliothèque de validation de schéma JavaScript et un moteur de validation de données asynchrone. Il vérifie les structures d'objets complexes et les tableaux imbriqués en appliquant des règles récursives et une exécution non bloquante basée sur des promesses pour assurer l'intégrité des données.
La bibliothèque fonctionne à la fois comme un validateur de contraintes d'objet et un pipeline de transformation de données. Elle permet l'assainissement, la coercition et le formatage des valeurs d'entrée via une séquence de fonctions qui s'exécutent avant et après le processus de validation principal.
Le moteur couvre une gamme de capacités incluant la validation imbriquée récursive, l'application de contraintes de schéma standard et l'intégration de logique métier personnalisée via des fonctions de validation sur mesure. Il fournit également des outils pour la personnalisation des messages d'erreur et la localisation via des chaînes statiques ou des fonctions dynamiques.
Features
- Asynchronous Validators - Executes validation rules as promises to allow for non-blocking remote checks and database lookups.
- Asynchronous Validation - Provides a non-blocking validation engine that utilizes promises for checks requiring external network or database calls.
- Schema Validation Libraries - Functions as a library for validating data objects against defined schemas using asynchronous logic.
- Asynchronous Validation Execution - Uses a promise-based execution model to ensure slow or remote validation checks do not block the main thread.
- Object Constraint Validation Engines - Checks objects against defined schemas and constraints to generate detailed reports of validation failures.
- Custom Validation Rules - Offers a framework for extending validation logic with domain-specific checks via bespoke functions.
- Asynchronous Validation Engines - Provides a validation system that processes complex object structures and nested arrays using non-blocking promise-based execution.
- Custom Validation Functions - Provides support for executing both synchronous and asynchronous custom validation logic on specific object fields.
- Data Logic Injection - Enables the integration of custom business logic into the validation process for data objects.
- Recursive Object Validation - Recursively traverses nested object hierarchies and arrays to enforce structural correctness across deep data structures.
- Runtime Schema Validations - Provides a runtime engine to verify that objects match predefined schemas and constraints during execution.
- Data Transformation Pipelines - Implements a pipeline to sanitize, coerce, and format input values before and after the primary validation process.
- Data Validation Schemas - Provides a comprehensive system for defining schemas and enforcing validation rules on JavaScript data objects.
- Data Transformation Pipelines - Implements a sequence of transformation functions to sanitize and coerce input values before and after validation.
- Constraint Mappings - Maps field descriptors to specific validator functions to enforce constraints based on types, patterns, and ranges.
- JavaScript Schema Validation - Verifies complex data objects against defined rules and constraints to ensure structural integrity within JavaScript applications.
- Form Validation - Provides asynchronous validation capabilities suitable for maintaining responsiveness in user-submitted form data.
- Standard Constraints - Implements built-in rules for type checking, required fields, and range limits to ensure data integrity.
- Value Transformations - Modifies input data values through transformation functions before and after the validation phase.
- Dynamic Error Message Resolution - Generates human-readable error messages by resolving expected and actual values at runtime based on the failure context.
- Pre-Validation Transformations - Applies sanitization and coercion transformations to input values before they are processed by validation rules.
- Validation Error Customizations - Allows developers to override default error messages with localized or dynamic text during the validation process.
- Data Validation - Asynchronous data validation.
