## What it is
VineJS is a fast, schema-based form data validation library for Node.js, designed to validate HTTP request bodies and JSON payloads with both runtime and static type safety. It offers 50+ validation rules, 12 schema types, conditional validation, custom error messages, and pre-compiled schemas for high performance.

## Use cases
- validate http request body in node.js backend
- validate json payloads against a schema
- validate html form data and normalize empty strings to null
- define conditional validation rules like requiredIf
- get typed validation output in typescript
- custom error messages for validation failures

## When to choose
- you need one of the fastest node.js validation libraries with pre-compiled schemas
- you want runtime and static type safety together
- you validate form data and need html form normalization helpers
- you need extensible custom rules, unions, and conditional groups

## When to avoid
- your project uses CommonJS since VineJS is ESM-only
- you need browser-side or frontend validation
- you want deeply composable schema pick/omit APIs, which VineJS intentionally limits

## Facets
- artifact type: library

- function: form-handling, serialization
- domain: web-development, backend, developer-tools
- platform: cli
