cardanocli-js-lambda

cardanocli-js

Fork Notes:

This is a fork of the original project to make the use suitable for AWS Lambda. The main difference is the introduction of seperate readable (./) and a write-able directories (/tmp) as Lambda can only write in /tmp.

Overview

This is a library, which wraps the cardano-cli with JavaScript and makes it possible to interact with the cli-commands much faster and more efficient.

This library is brought to you by Berry Pool. You can support our work by delegating to our pool.

NPM

npm install cardanocli-js

From source

git clone https://github.com/Berry-Pool/cardanocli-js.git
cd cardanocli-js
npm install

Getting started

const CardanocliJs = require("cardanocli-js");
const shelleyGenesisPath = "/home/ada/mainnet-shelley-genesis.json";

const cardanocliJs = new CardanocliJs({ shelleyGenesisPath });

const createWallet = (account) => {
  const payment = cardanocliJs.addressKeyGen(account);
  const stake = cardanocliJs.stakeAddressKeyGen(account);
  cardanocliJs.stakeAddressBuild(account);
  cardanocliJs.addressBuild(account, {
    paymentVkey: payment.vkey,
    stakeVkey: stake.vkey,
  });
  return cardanocliJs.wallet(account);
};

const createPool = (name) => {
  cardanocliJs.nodeKeyGenKES(name);
  cardanocliJs.nodeKeyGen(name);
  cardanocliJs.nodeIssueOpCert(name);
  cardanocliJs.nodeKeyGenVRF(name);
  return cardanocliJs.pool(name);
};

const wallet = createWallet("Ada");
const pool = createPool("Berry");

console.log(wallet.paymentAddr);
console.log(pool.vrf.vkey);

Structure

All files will be stored and used in the directory you choose when instantiating CardanocliJs (dir). The directory is split in two subfolders tmp and priv. In the tmp folder are stored protocol paramters, raw transactions, signed transactions and witnesses with unique identifiers. The priv folder is again divided into two subolders holding on one site the pools pool and on the other side the wallets wallet (like CNTools structure).

Example structure:

dir
    tmp
        <tx_1.raw>
        ...
    priv
        pool
            Berry
                <Berry.node.vkey>
                <Berry.node.skey>
                <Berry.vrf.vkey>
                ...
        wallet
            Lovelace
                <Lovelace.payment.vkey>
                <Lovelace.stake.skey>
                ...

Tests

Install npm dev dependencies using npm install --also=dev.

Tests are using Jest framework and can be run by using npm -s run test command.

To configure the test suite, make a copy of .env.dist and rename it .env. Then change all parameters values to fit your environment.

Caution: The TEST_WORKSPACE_DIR will be deleted at the end of the test suite. NEVER USE AN EXISTING DIRECTORY !!! You may disable this behavior by commenting the cleanup function in test/index.test.js:

afterAll(() => {
    // cleanUpTestDirectory();
});
