eosio wasm js

eosio-wasm-js is a tool that converts EOSIO blockchain types into a WASM hex string, making it handy for serializing actions in JS environments for EOSIO transactions.

Installation

For Node.js

$ npm i eosio-wasm-js

For Deno, make sure you include this import in your deno.json file:

{
  "imports": {
   "eosio-wasm-js/": "https://deno.land/x/eosio_wasm_js/"
  }
}

Example

import serialize from "eosio-wasm-js/serialize.js";

console.log(serialize.asset("EOS"));

The logged output was “000000000000000001454f5300000000”.

Support

• Node.js >= 13.
• Browser list > 0.5%, not OperaMini all, not IE > 0, not dead.

Consider a BigInt polyfill library for safari 13.
