@jdsalasc/solvejs-validators

Zero-dependency validators for JavaScript and TypeScript forms and API payloads.

Utilities

• Structured validators returning { ok, code, message }
• validateCellphoneNumber, validateEmail, validateHttpUrl
• validateName, validateUsername, validateAddressLine, validatePostalCode (country-aware)
• validateStrongPassword, validateCreditCardNumber
• validateUuidV4, validateIpv4, validateIsoDateString
• Boolean wrappers (isX) for quick checks

When to use this package

Use it when you need reusable validation rules with explicit error codes instead of plain true/false outputs.

Limitations and Constraints

• Country coverage is explicit and incremental; unsupported countries return structured errors.
• Validators are format-focused and do not verify external authority databases.
• Deprecated typo aliases (isAddresDirection, isAddresDirrection) remain in 1.x for compatibility and are planned for removal in 2.0.0.

Install

npm i @jdsalasc/solvejs-validators
