  --explorer, -e  Need up explorer (port 3000)                         [boolean]

Usage example

Step 1. Up the node and create the state

node-state -n -m typescript -o ./tests/state.ts;

Step 2. Write some tests with some test framework

import { NODE_URL, STATE, CHAIN_ID, MASTER_ACCOUNT } from './test/state.ts';
import { transfer, broadcast, waitForTx } from '@decentralchain/waves-transactions';


it('Create transfer transaction', async () => {
    const tx = transfer({ 
        recipient: `alias:${CHAIN_ID}:${MASTER_ACCOUNT.ALIAS}`,
        amount: 1000
    }, STATE.ACCOUNTS.SIMPLE.seed);
    await broadcast(tx);
    await waitForTx(tx.id, { apiBase: NODE_URL }); // Transaction broadcast success!
});
