VineJS is a framework agnostic validation library for Node.js. If you are looking for a type-safe and feature-rich validation library, VineJS might be it.

• Type-safe: Alongside runtime validations, the validated output in VineJS is completely type-safe.
• 50+ validation rules: We ship with an ever-growing massive collection of validation rules.
• 13 schema types: Use in-built schema types or create a custom one to represent the core data types of your application.
• Support for custom messages: First-class workflow for defining custom error messages.
• Unions for conditional validation: Unions in VineJS are built for writing conditional validations. For example: Ask for appointment_date when has_appointment is true. Also, the output is type-safe.
• Error reporters: Structure the errors using custom error reporters.

• Performance - VineJS is built around performance. It is 5x-10x faster than Zod and Yup.
• Built for validating form data and JSON payloads - VineJS handles the HTML forms serialization quirks so that you never have to perform data normalization yourself.
