Rules examples

{
    prior: 2,
    condition: {
        unitMeasure: {
            name: "test-regex",
            value: "(jar|bottle|inch)"
        }
    },
    convertion: {
        unitQuantity: {
            name: "math-c2",
            value: ["packageUnitQuantity"]
        },
        unitMeasure: {
            name: "setval-c1",
            value: ["packageUnitMeasure"]
        }
    }
}

{
    prior: 2,
    condition: {
        unitMeasure: {
            name: "test-regex",
            value: "(ct|count|counts|ctn)"
        }
    },
    convertion: {
        packageUnitQuantity: {
            name: "math-c2",
            value: ["unitQuantity"]
        },
        packageUnitMeasure: "count"
    }
}

Coding

const packer = require('@emealscom/packer')

const packerRequest = {
    description: "Broccoli",
    offerDescription: "Pack of 4 Broccoli",
    unitMeasure: "grams",
    unitQuantity: 480,
    packageUnitMeasure: "ounces",
    packageUnitQuantity: 12
};

console.log(packer.convert(packerRequest));

Result

➜  test node index
{ estimatedQuantity: 2, status: true }
