FunscScript JS Runtime

The @tewelde/funscscript package exposes the FunscScript expression runtime for Node.js and browser environments. It mirrors the .NET interpreter so the same scripts can be evaluated on either platform.

Install

npm install @tewelde/funscscript

Usage

import { Engine } from '@tewelde/funscscript';

const provider = new Engine.DefaultFsDataProvider({
  gross: 5200,
  taxRate: 0.12
});

const result = Engine.evaluate('{ net:(x)=>x*(1-taxRate); return net(gross); }', provider);

console.log(result);

The package ships CommonJS (require), ESM (import), and browser-friendly builds together with TypeScript definitions.
