Language Bindings

Wvlet provides SDKs for various programming languages, allowing you to compile Wvlet queries to SQL directly from your preferred language environment.

Available SDKs​

Python SDK​

PyPI version

The Python SDK provides native performance with easy installation via pip:

pip install wvlet
from wvlet import compile

sql = compile("from users select name, age where age > 18")
print(sql)  # SELECT name, age FROM users WHERE age > 18

Features:

  • Native library for high-performance compilation
  • Automatic CLI fallback
  • Support for all Wvlet features
  • Integration with pandas, DuckDB, SQLAlchemy

TypeScript/JavaScript SDK​

npm version

The TypeScript SDK enables Wvlet compilation in Node.js and browsers:

npm install wvlet
import { WvletCompiler } from 'wvlet';

const compiler = new WvletCompiler();
const sql = compiler.compile('from users select name, age where age > 18');
console.log(sql);  // SELECT name, age FROM users WHERE age > 18

Features:

  • Pure JavaScript via Scala.js compilation
  • Works in browsers and Node.js
  • Full TypeScript support
  • No native dependencies

Planned SDKs​

The following language bindings are planned for future releases:

  • Java/Scala - Native JVM integration
  • Ruby - Ruby gem with native extensions
  • Rust - Cargo crate with native bindings
  • Go - Go module with CGO bindings
  • C/C++ - Header-only library

Native Library​

All language SDKs use the same underlying native library (libwvlet) for consistent behavior and performance across languages. The native library is built using Scala Native and provides a C-compatible API.

Contributing​

We welcome contributions to add more language bindings! If you're interested in creating an SDK for your favorite language:

  1. Check the Python SDK implementation as a reference
  2. Use the native library API defined in WvcLib.scala
  3. Follow the language's best practices for packaging and distribution
  4. Submit a pull request with your implementation
