qail-wasm

WebAssembly bindings for QAIL - the AST-native query language.

Features

• 🚀 Zero runtime dependencies - Pure WebAssembly
• 🔒 Type-safe SQL generation - From AST, not strings
• 🌐 Browser & Node.js compatible
• ⚡ Fast - Native-speed query parsing

Installation

[!CAUTION] Alpha Software: QAIL is currently in alpha. While we strive for stability, the API is evolving to ensure it remains ergonomic and truly AST-native. Do not use in production environments yet.

npm install qail-wasm

Usage

import init, { parse_and_transpile } from 'qail-wasm';

await init();

// Parse QAIL syntax and transpile to SQL
const sql = parse_and_transpile("get users : id, name [ active = true ]", "postgres");
console.log(sql);
// → SELECT id, name FROM users WHERE active = true
