Lightweight JavaScript library for creating, signing, and broadcasting transactions on the Steem blockchain

Why this?

steem-js and dsteem libraries are not easy to integrate and in some cases are incompatible with some frameworks like Nativescript

NativeScript is an open-source framework to develop apps on the Apple iOS and Android platforms. It was originally conceived and developed by Progress. NativeScript apps are built using JavaScript, or by using any language that transpiles to JavaScript, such as TypeScript. - Wikipedia

This library is a solution to such cases when official libraries are not working. And also an alternative for just creating, signing, and broadcasting transactions.

How Steem-tx works:

I'm preparing another post about this library. A full instruction on how to serialize and sign Steem transactions with JavaScript. It will take a few days to be ready.

Installation

npm install steem-tx --save

Usage

Create transaction:

const steemTx = require('steem-tx')
const operations = [
  [
    'vote',
    {
      voter: 'guest123',
      author: 'guest123',
      permlink: '20191107t125713486z-post',
      weight: 9900
    }
  ]
]

const tx = new steemTx.Transaction()
tx.create(operations).then(() => console.log(tx.transaction))

Sign transaction:

(multi signature is supported)

// please use this key just for testing purposes
const myKey = '5JRaypasxMx1L97ZUX7YuC5Psb5EAbF821kkAGtBj7xCJFQcbLg'
const privateKey = steemTx.PrivateKey.from(myKey)

tx.sign(privateKey)
console.log(tx.signedTransaction)

Broadcast transaction:

tx.broadcast().then(res => console.log(res))

Make node call:

steemTx.call('condenser_api.get_accounts', [['mahdiyari']]).then(res => console.log(res))

npm package: https://www.npmjs.com/package/steem-tx


Feel free to test, use, share!

Future plans?

I'm building different applications mainly for Steem blockchain and I will try to keep this library as light as possible but also, useful with main functions for interacting with Steem blockchain. I believe having more tools will help grow use cases of Steem blockchain.

Many features, like getting posts and accounts are easy to implement with basic api calls. But serializing and signing transactions are a little bit complex to be implemented. That's why I decided to prepare another post about it and explain as much as I can.

Let's hope and work for a better future for the people in the World and on the Steem blockchain ❤

I love how this is a minimal, yet complete, Javascript library for Steem. It is very similar to how I would design a Javascript library if we were to move away from steem-js and dsteem. Great job! I hope it gains traction.

the code looks perfect to me

Somewhat echoing the comments of @vandeberg, I'd love to see similar minimal yet complete Steem libraries for other popular languages.

good stuff man

Neat :) @tipu curate

At the first look it seems pretty good! 💪

Great job!!!!

looks great..... love it...😍

i love it.😍😍

Java!!!

Is there any example of sending a transaction (STEEM) to multiple people at once?

Put your transfers inside operations array in the first code snippet just like vote operation
also https://developers.steem.io/apidefinitions/broadcast-ops#broadcast_ops_transfer may help

Nice post man! :D

It is like

Amazing!! 🤪🤪

WOW glad to se you getting upvotes from non bid bots . ocdb won! this is crazy cool to see developers getting funded this much at 15 cent steem! ,

i hope to see this formlized this into a develoepr wps, just for developers, i can use SQRL and get us a token and our own proposal system, like imagine , giuthub inside vessel wallet sort of thing :D ok man im so tired g2g but good job!

@mahdiyari id like to recruit you to work with telos community, not to take you away from steem just to enhance it... please come check out https://t.me/hellotelos id love to gfet your helpo with cross chain work, telos is a land of opportunity and IBC i can help steem with telos and this is great stuff i will send u 1 TLOSP right now with @banjo bot by inertia :0

Thank you
but, I usually work for myself

well thats what im talking about.... you would make your own proposals and get funding on telos...

Join Palnet, Neoxian, Steemleo, steempeak and other tags to earn tokens for your content! You could have earned a lot more with those tags if they were used at all. Anyways, those are just some ideas. Its nice to see that SteemIt had SMT's and we can earn different tokens now! Nice post btw, its 1 AM but it was still fun to read.

to ppl readin i havent tested it

but steem can use some interesting

he's also not my friend he downvoted me, but

Perfect, it looks great !!

Best post on the blockchain right now! This is where everybody with investment (SP) should upvote right now. This post will pillage all the small posts with under $10 payout, for even greater returns for all curators. Get your upvotes in now!! #NewSteem #HF21

I'm planning to join dtube and I think it's an interesting app. There are particular tags where your videos can be shared with, I'm planning to add more of these tags in my videos and you can try it too, it will help your video to be generated with the right audience or people and it's going to be fun. Best of luck to you and me too.
