Function packData

Serializes any value of packable type to its optimized binary representation identical to the one used by PACK and UNPACK Michelson instructions. Without a type definition (not recommended) the data will be encoded as a binary form of a generic Michelson expression. Type definition allows some types like timestamp and address and other base58 representable types to be encoded to corresponding optimized binary forms borrowed from the Tezos protocol

const data: MichelsonData = {
    string: "KT1J4E79F1qL6kGBSQ3yXBdXmuq5j4FNThK2%main"
};

const typ: MichelsonType = {
    prim: "address"
};

const packed = packData(data, typ);

// 050a0000001a0167ea84b1082efb9619d6ce04e033633906636e1d006d61696e

Without a type definition the base58 encoded address will be treated as a string

const data: MichelsonData = {
    string: "KT1J4E79F1qL6kGBSQ3yXBdXmuq5j4FNThK2%main"
};

const packed = packData(data);

// 0501000000294b54314a344537394631714c366b474253513379584264586d7571356a34464e54684b32256d61696e
