Create npm package for JavaScript/TypeScript projects

[rz1989s]

Goal

Provide npm package for using LUMOS in JavaScript/TypeScript projects without Rust toolchain.

Phase: 6.2 Tooling Ecosystem

---

Problem

JS/TS developers need Rust installed:

• ❌ Must install Cargo to use LUMOS
• ❌ Not idiomatic for JS projects
• ❌ Slower onboarding

---

Solution

Publish npm package with WASM or Node binary.

Installation

npm install @getlumos/cli
# or
yarn add @getlumos/cli

Usage

import { generate } from '@getlumos/cli';

await generate('schema.lumos', {
  outputRust: 'src/generated.rs',
  outputTs: 'src/generated.ts',
});

CLI:

npx lumos generate schema.lumos

---

Implementation Options

Option 1: WASM (Preferred)

• Compile LUMOS core to WASM
• Works in Node.js and browsers
• No platform-specific binaries

Option 2: Native Binaries

• Ship binaries for each platform
• Faster than WASM
• More complex to maintain

📥 User Installation

# Install globally
npm install -g @getlumos/cli

# Use CLI
lumos generate schema.lumos
lumos validate schema.lumos

# Or run directly
npx @getlumos/cli generate schema.lumos

Programmatic Usage:

import { generate, validate } from '@getlumos/cli';

// Generate code
const result = await generate('schema.lumos', {
  outputRust: 'src/generated.rs',
  outputTypeScript: 'src/generated.ts'
});

// Validate schema
const validation = await validate('schema.lumos');
if (validation.valid) {
  console.log('Schema is valid!');
}
