V8n
v8n 是一款 JavaScript 数据验证库，用于验证值、对象和数组是否符合特定标准。它作为一个基于模式的验证器和异步验证引擎，利用流畅的 API 构建可链式调用的规则和约束序列。
该框架因其能够在验证过程中执行 Promise 和网络请求以确定值是否有效而脱颖而出。它允许创建可重用的验证模式，并提供了一个可自定义的规则框架，用户可以在其中定义自己的逻辑并配置如何返回错误结果。
该库涵盖了广泛的验证功能，包括针对原始类型和原型的数据类型验证、通过正则表达式和字符集的字符串内容验证，以及数值约束。它还支持复杂的对象验证、集合和数组元素验证，以及用于反转规则或处理可选值的条件逻辑。
该系统专为详细的错误收集而设计，根据每个定义的规则评估值，以收集完整的失败列表，而不是在第一个错误处停止。
Features
- Fluent Validation Rules - Ships a fluent API that allows developers to construct validation pipelines through a sequence of chainable methods.
- JavaScript Schema Validation - Provides a library to verify complex JavaScript object structures against defined rules and constraints.
- Data Validation Libraries - Functions as a tool for parsing and validating JavaScript data structures against predefined schemas.
- Asynchronous Validators - Provides mechanisms for asynchronous validation checks that require external API calls or database lookups.
- Asynchronous Validation Pipelines - Supports asynchronous validation rules that execute promises, enabling network requests and database lookups during the verification process.
- Asynchronous Validation Engines - Implements a non-blocking engine that processes complex object structures using recursive rules and promises.
- Asynchronous Validators - Supports custom validation rules that return promises for performing asynchronous external lookups.
- Customizable Validation Frameworks - Provides a framework for creating user-defined validation logic and configuring how error results are returned.
- Data Type Validation - Checks if a value matches a specific type or prototype constructor to ensure data conforms to expected structures.
- Collection Constraints - Includes checks for the length of arrays or strings and verifies if they contain specific required items.
- Element-Level Validation - Provides capabilities to ensure that individual elements within a collection satisfy specific validation rules.
- Object Structure Validations - Provides capabilities to verify that objects conform to specific key-value patterns and strictly manage unauthorized properties.
- Strict Object Validation - Ensures objects conform to specific key-validation pairs and supports strict property checking.
- Cumulative Error Collection - Implements a validation engine that gathers all failures in a rule chain instead of short-circuiting after the first error.
- Numeric Constraint Validation - Verifies numeric constraints including integer status, positivity, parity, and specific range boundaries.
- Chainable Validation APIs - Uses a chainable API pattern to declaratively specify multiple validation rules and sanitizers.
- Schema Composition Libraries - Provides a compositional approach to building complex validation structures by nesting and chaining reusable schema primitives.
- String Content Constraints - Verifies string properties such as case, character sets, regex patterns, and specific start or end characters.
- Reusable Data Schemas - Allows for the creation of reusable validation schemas to maintain consistent data constraints across applications.
- Custom Validation Rules - Offers a framework for extending the library with user-defined validation logic via a chainable interface.
- Data Validation Schemas - Allows exporting pre-configured validation chains as reusable modules to maintain consistent constraints.
- Error Handling Strategies - Implements configurable strategies for how validation results are returned to the application.
- Dynamic Type Checking - Determines the data type of a value at runtime using prototypes and native types to drive validation logic.
- Validation Control Flow - Provides conditional logic to invert rule results, handle optional values, or require at least one passing validation.
- Validation Output Modes - Allows switching the validation output mode between boolean values, detailed error lists, or thrown exceptions.
- Data Validation - Fluent JavaScript validation library.
