# Blockchain Data Formatters

# Formatting a large number

Using Wax Formatters, you can format numbers represented as string, number, BigInt and long using formatNumber method

import { createHiveChain } from '@hiveio/wax';

const chain = await createHiveChain();

const output = chain.formatter.formatNumber(76543212345678, 3, "en-US");

console.log(output);
76,543,212,345,678.000

# Formatting NAI Asset

If you want to format a string, use waxify literal

import { createHiveChain } from '@hiveio/wax';

const chain = await createHiveChain();

// Data from blockchain
const naiAsset = {
  amount: "300000",
  precision: 3,
  nai: "@@000000021"
};

const output = chain.waxify`Amount: ${naiAsset}`;

console.log(output);
Amount: 300.000 HIVE

# Formatting Transaction

import { createHiveChain } from '@hiveio/wax';

const chain = await createHiveChain();

// Data from blockchain
const tx = {
  ref_block_num: 1959,
  ref_block_prefix: 3625727107,
  expiration: "2023-11-09T22:01:24",
  operations: [
    {
      type: "transfer_operation",
      value: {
        from: "oneplus7",
        to: "kryptogames",
        amount: naiAsset,
        memo: "Roll under 50 4d434bd943616"
      }
    }
  ],
  extensions: []
};

const output = chain.waxify`Tx: #${tx}`;

console.log(output);
Tx: #3725c81634f152011e2043eb7119911b953d4267

# Formatting entire transaction without replacing with transaction id

Sometimes there is a need to convert an entire transaction object, but you do not want it to be replaced with the string. You can achieve that by using format method and extending the default Wax Formatter with your custom options, e.g.:

import { createHiveChain } from '@hiveio/wax';

const chain = await createHiveChain();

// Data from blockchain
const tx = {
  ref_block_num: 1959,
  ref_block_prefix: 3625727107,
  expiration: "2023-11-09T22:01:24",
  operations: [
    {
      type: "transfer_operation",
      value: {
        from: "oneplus7",
        to: "kryptogames",
        amount: naiAsset,
        memo: "Roll under 50 4d434bd943616"
      }
    }
  ],
  extensions: []
};

const formatter = chain.formatter.extend({ transaction: { displayAsId: false } });

const output = formatter.format(tx);

console.log(output);
{
  ref_block_num: 1959,
  ref_block_prefix: 3625727107,
  expiration: "2023-11-09T22:01:24",
  operations: [
    {
      type: "transfer_operation",
      value: {
        from: "oneplus7",
        to: "kryptogames",
        amount: naiAsset,
        memo: "Roll under 50 4d434bd943616"
      }
    }
  ],
  extensions: []
}
