Vest Form Validation Framework

Vest is a declarative and framework-agnostic JavaScript validation framework that enables developers to write validation logic using a syntax familiar to unit testing frameworks like Jest or Mocha. It aims to separate validation concerns from UI logic, promoting cleaner components and easier testing. Currently stable at version 6.3.2, Vest offers robust features including asynchronous validation support, strong TypeScript type safety, server-side rendering (SSR) compatibility with state hydration, and extensibility for custom rules. It distinguishes itself by managing validation state intelligently, handling dependent fields, and providing a powerful assertion library (`enforce`). The project maintains a consistent release cadence with regular patch and minor updates, and significant architectural shifts between major versions. Vest is designed for complex validation scenarios across various JavaScript environments (React, Vue, Svelte, Angular, Node.js, vanilla JS) and implements the Standard Schema specification.
