Lightweight and complete JavaScript library for using Hive blockchain in Javascript environments such as Web or NodeJS.
Most lightweight library to use in your applications.
Some libraries are not easy to integrate and in some cases are incompatible with some frameworks like Nativescript
This library is a solution to such cases when official libraries are not working. And also an lightweight alternative for other libraries.
npm install hive-tx --save
Browser:
<script src="https://cdn.jsdelivr.net/npm/hive-tx/dist/hive-tx.min.js"></script>
or
<script src="dist/hive-tx.min.js"></script>
hiveTx is available after including /dist/hive-tx.min.js file in your html file.
NodeJS:
const hiveTx = require('hive-tx')
Configuration
Set or get configs:
// default values already defined in config.js
hiveTx.config.node = "https://api.hive.blog"
hiveTx.config.chain_id = "beeab0de00000000000000000000000000000000000000000000000000000000"
hiveTx.config.address_prefix = "STM"
Create transaction:
const tx = new hiveTx.Transaction(trx?)
or
const tx = new hiveTx.Transaction()
tx.create(operations, expiration = 60)
Example:
const operations = [
[
'vote',
{
voter: 'guest123',
author: 'guest123',
permlink: '20191107t125713486z-post',
weight: 9900
}
]
]
const tx = new hiveTx.Transaction()
tx.create(operations).then(() => console.log(tx.transaction))
Sign transaction:
const myKey = '5JRaypasxMx1L97ZUX7YuC5Psb5EAbF821kkAGtBj7xCJFQcbLg'
const privateKey = hiveTx.PrivateKey.from(myKey)
tx.sign(privateKey)
console.log(tx.signedTransaction)
Broadcast transaction:
tx.broadcast().then(res => console.log(res))
Get transaction digest and id Will return the hash and transaction id without broadcasting the transaction.
const digest = tx.digest()
// { digest: Buffer, txId: string }
Make node call:
hiveTx.call(method, params = [], timeout = 10): Promise
Example:
hiveTx.call('condenser_api.get_accounts', [['mahdiyari']]).then(res => console.log(res))
Sign message and verify sginature:
hiveTx.PrivateKey.sign(message: Buffer)
hiveTx.PublicKey.verify(message: Buffer, signature: Signature)
Example:
const { sha256 } = require( 'hive-tx/helpers/crypto' )
const privateKey = hiveTx.PrivateKey.from('5JRaypasxMx1L97ZUX7YuC5Psb5EAbF821kkAGtBj7xCJFQcbLg')
const publicKey = hiveTx.PublicKey.from('STM6aGPtxMUGnTPfKLSxdwCHbximSJxzrRjeQmwRW9BRCdrFotKLs')
const message = sha256('testing')
const signature = privateKey.sign(message)
const verify = publicKey.verify(message, signature) // true
Or create Sginature from string:
const signature = hiveTx.Signature.from('1f019dc13a308cef138162cc16ab7c3aa1891941fddec66d83ff29b01b649a86600802d301f13505abc8c9ccbbeb86852fc71134fe209a6e717c6fd7b4cd1505a2')
