gnark witness serializer in js

npm i gnark-witnejs

Usage

import serialize from "gnark-witnejs"

const inputs = { x: 3n, y: 35n, z: [ [ 0n, 99n ], 77n ] }
const publics = { x: true } // indicates public inputs
const opts = {/* modulus: BN254_R, publicOnly: false */}

const buf = serialize(inputs, publics, opts)

Make sure that:

• input fields appear in the same order as in the golang struct
• the input object does not contain nested objects

  nested arrays are supported though
