validatorjs is a JavaScript data validation library inspired by Laravel's Validator, usable in both the browser and Node.js. It provides declarative, readable validation rules with multilingual error messages and support for nested and wildcard rules.

Use cases

• validate form input in the browser
• validate request payloads in Node.js
• validate nested JSON objects with rules
• validate arrays of objects with wildcard rules
• generate localized validation error messages
• port Laravel-style validation rules to JavaScript

When to choose

• you want Laravel-style declarative validation rules in JavaScript
• you need one validation library that works in both browser and Node.js
• you need multilingual validation error messages
• you need to validate nested or array-based data structures

When to avoid

• you need schema-based validation with TypeScript type inference (consider zod or joi)
• you need high-performance validation of very large datasets
• you want a framework-integrated validator with reactive form bindings
