# Introduction
v9s means validations. It is a small validation library with no dependencies and full TypeScript support. Use chains of rules to get a complex validation.
# Motivation
The searching of a small and flexible validation library which works with and without TypeScript was failed. Some libraries work with only with or without TypeScipt, others contain too many useless prepared validation rules, which aren't used in our project.
# Goals
So, our goal is a small and flexible library without external dependencies that works perfectly good with and without TypeScript.
