hive-tx

The most lightweight library for Hive blockchain while being a complete library. Regularly maintained to support the latest features of the blockchain. For Web and NodeJS.

Library size: ~29KB minified+gzipped (including all the dependencies)

Comprehensive Documentation

• 🚀 Quick Start Guide - Get up and running in minutes
• 💻 Examples - Practical usage examples

Installation

# Require nodejs +20
npm install hive-tx --save

Usage

import { Transaction, PrivateKey, callRPC } from 'hive-tx'

The library has two build outputs:

• ES Module (esm)
• CommonJS (cjs)

Your application will automatically pick the right build for your environment but you can also import either of them directly from hive-tx/esm and hive-tx/cjs.

There is also a browser build which you can use like this:

<script src="https://cdn.jsdelivr.net/npm/hive-tx@7/dist/browser/hive-tx.min.js"></script>
<!-- hiveTx will be available globally -->

Quick Usage Examples

New Transaction API (v7+)

import { Transaction, PrivateKey } from 'hive-tx'

// Create and broadcast a vote
const tx = new Transaction()
await tx.addOperation('vote', {
  voter: 'your-username',
  author: 'post-author',
  permlink: 'post-permlink',
  weight: 10000 // 100%
})

const key = PrivateKey.from('your-private-key')
tx.sign(key)
const result = await tx.broadcast()
console.log('Vote successful!', result.result.tx_id)

Transfer HIVE

import { Transaction, PrivateKey } from 'hive-tx'

const tx = new Transaction()
await tx.addOperation('transfer', {
  from: 'sender',
  to: 'receiver',
  amount: '1.000 HIVE',
  memo: 'Thanks for your help!'
})

const key = PrivateKey.from('your-active-key')
tx.sign(key)
const result = await tx.broadcast()
console.log('Transfer successful!', result.result.tx_id)

API Calls

import { callRPC, callREST, callWithQuorum } from 'hive-tx'

// Get account information
const accounts = await callRPC('condenser_api.get_accounts', [['username']])
console.log('Account:', result[0])

// Get blockchain properties
const props = await callRPC('condenser_api.get_dynamic_global_properties')
console.log('Head block:', props.head_block_number)

const balance = await callREST('balance', '/accounts/{account-name}/balances', {
  'account-name': 'alice'
})
console.log(balance)

// Cross-check the result of the call with 2 nodes
const accounts = await callWithQuorum('condenser_api.get_accounts', [['username']], 2)
console.log('Account:', result[0])

Key Management

import { PrivateKey } from 'hive-tx'

// Create keys in multiple ways
const key1 = PrivateKey.from('5JdeC9P7Pbd1uGdFVEsJ41EkEnADbbHGq6p1BwFxm6txNBsQnsw')
const key2 = PrivateKey.randomKey()
const key3 = PrivateKey.fromLogin('username', 'password', 'posting')
const key4 = PrivateKey.fromSeed('my-secret-seed')

Configuration

import { config } from 'hive-tx'

// Configure API nodes with failover
// Default nodes that are already set:
config.nodes = [
  'https://api.hive.blog',
  'https://api.deathwing.me',
  'https://api.openhive.network',
  'https://rpc.mahdiyari.info',
  'https://techcoderx.com',
  'https://hiveapi.actifit.io',
  'https://api.c0ff33a.uk'
]

// Custom timeout and retry settings
config.timeout = 10_000 // 10 seconds
config.retry = 8 // 8 retry attempts before throwing an error

Breaking Changes in v7

v7 is a complete TypeScript rewrite with significant API improvements. See CHANGELOG.md for full details.

Key Breaking Changes:

• tx.create() => await tx.addOperation(opName, opBody)
• call() => callRPC() - Returns result directly, throws RPCError on errors
• Transaction.broadcast(timeout?, retry?) => Transaction.broadcast(checkStatus?)
• All timeout/expiration values now in milliseconds (was seconds)
• new Transaction(transaction) => new Transaction({transaction, expiration})
• Transaction.signedTransaction removed - Use Transaction.transaction
• config.node (string) => config.nodes (array)
• config.healthcheckInterval removed

Migration Examples:

// v6: Creating transactions
const tx = new Transaction()
await tx.create([['vote', { voter: 'alice', author: 'bob', permlink: 'post', weight: 10000 }]])

// v7: Creating transactions
const tx = new Transaction()
await tx.addOperation('vote', { voter: 'alice', author: 'bob', permlink: 'post', weight: 10000 })

// v6: API calls
const result = await call('condenser_api.get_accounts', [['alice']])
const accounts = result.result

// v7: API calls
const accounts = await callRPC('condenser_api.get_accounts', [['alice']])

// v6: Configuration
config.node = 'https://api.hive.blog'
config.timeout = 10 // seconds

// v7: Configuration
config.nodes = ['https://api.hive.blog', 'https://api.deathwing.me']
config.timeout = 10_000 // milliseconds

What's new in v7

• Codebase reworked in TypeScript
• All methods now have good JSDoc documentation
• Added types for all operations
• Added callWithQuorum() - JSONRPC call that cross-checks the result with multiple nodes
• Added callREST() with full typing for new REST APIs
• Added tests including operation tests to keep them up to date with hived
• Added docs/EXAMPLES.md and docs/QUICKSTART.md
• Output 3 builds: ESM, CJS, UMD minified .js for browser
