ForgJs is a lightweight JavaScript object validator that lets developers define rules for validating values like emails, passwords, numbers, dates, and URLs. It supports custom rules, custom error messages, and batch validation of object arrays.

Use cases

• validate form input like emails and passwords in javascript
• validate object schemas in nodejs
• check that values match type and range constraints
• get custom error messages for invalid fields
• validate arrays of objects in bulk

When to choose

• you need a small, dependency-free validator for plain JavaScript objects
• you want simple rule-based validation with custom error messages
• you're validating common types like email, password, url, int, and date

When to avoid

• you need async or schema-based validation with rich ecosystem support (consider Joi, Zod, or Yup)
• you need TypeScript-first type inference from your schemas
• you need actively developed software with frequent updates
