# AnyVali

> Native validation libraries for 10 languages, one portable schema model.

AnyVali is a family of native validation libraries that share a single portable schema model across 10 programming languages: JavaScript/TypeScript, Python, Go, Java, C#, Rust, PHP, Ruby, Kotlin, and C++.

Write schemas in your host language using idiomatic builder APIs, export them to a canonical JSON document, and import them in any other supported SDK. All SDKs pass a shared conformance test suite ensuring identical behavior.

## Install

```
npm install anyvali          # JavaScript / TypeScript
pip install anyvali              # Python
go get github.com/BetterCorp/AnyVali/sdk/go  # Go
cargo add anyvali                # Rust
dotnet add package AnyVali       # C#
composer require anyvali/anyvali # PHP
gem install anyvali              # Ruby
```

## Type Inference

All 10 SDKs provide static type inference. In TypeScript, use `Infer<T>` to extract the output type from a schema (similar to Zod's `z.infer`). Other SDKs use generics (`Schema<T>` in C#/Kotlin/Java, `Generic[T]` in Python), generic helpers (`TypedParse[T]()` in Go, `parse_as<T>()` in Rust/C++), or tooling annotations (`@template` phpDoc in PHP, RBS signatures in Ruby).

## Quick Example (TypeScript)

```typescript
import { object, string, int64, importSchema } from "anyvali";

const User = object({
  id: int64(),
  email: string().format("email"),
});

const result = User.safeParse({ id: 42, email: "team@anyvali.dev" });
const doc = User.export(); // portable JSON
const imported = importSchema(doc); // import in any SDK
```
