const { mpapi } = require('mpapi'); // Connect to

mpapi.node.setProvider("http://127.0.0.1:8732");
mpapi.node.setDebugMode(true);

1. Create new account

// Generate seed phrase
const mnemonic = mpapi.crypto.generateMnemonic();
// Generate new keys of account
const keys = mpapi.crypto.generateKeys(mnemonic);

2. Get existing account by private key

const extractedKeys = mpapi.crypto.extractKeys('edsk3uku2wuuMztoazUmusXoRgFYRJyPyN9QYdoPDZo6JEKM3QMd5t');

3. Get plex_balance

const plex_balance = utility.totez(await mpapi.rpc.getPlexBalance(extractedKeys.pkh));)

4. Get mine_balance

const mine_balance = utility.totez(await mpapi.rpc.getMineBalance(extractedKeys.pkh));

5. Send mine to another account

const operations = await mpapi.rpc.mine_transfer(
  extractedKeys.pkh, 
  extractedKeys, 
  'mp1MN1YB8ofoZokHyUAmH9oYKfxEHqF1XkT7', // Receiver
  100, // Amount of mine
  1 // Default fee
);

6. Send plex to another account

const operations = await mpapi.rpc.plex_transfer(
  extractedKeys.pkh, 
  extractedKeys, 
  'mp1MN1YB8ofoZokHyUAmH9oYKfxEHqF1XkT7', // Receiver
  100, // Amount of plex
  1 // Default fee (mine value)
);

7. Set delegate

const operations = await mpapi.rpc.setDelegate(
  extractedKeys.pkh, 
  extractedKeys, 
  'mp1FCcGeqnRG2wawPaerF7JbY8EQ8dvm8wig', // Delegate address
  1 // Default fee
);

8. Undelegate

const operations = await mpapi.rpc.setDelegate(
  extractedKeys.pkh, 
  extractedKeys, 
  undefined, 
  1 // Default fee
);

9. Looging for operation in blocks

const blockHash = await mpapi.rpc.findOperation(
  'oo7D7FnyLeDL9VCNiXWY9cty8MvTzX8HDSGmuqGDfSNSwnwLogm',
  50 // Count blocks ago);

10. Looging for operation in blocks

const blockHash = await mpapi.rpc.awaitOperation(
  'oo7D7FnyLeDL9VCNiXWY9cty8MvTzX8HDSGmuqGDfSNSwnwLogm');

12. Example of catching errors

try {
  const blockHash = await mpapi.rpc.findOperation(
    'oo7D7FnyLeDL9VCNiXWY9cty8MvTzX8HDSGmuqGDfSNSwnwLogm',
    2
  );
} catch (error) {
  console.log(error)
}
