Examples

Broadcast Vote

var steem = require('steem');
var wif = steem.auth.toWif(username, password, 'posting'); steem.broadcast.vote(wif, voter, author, permlink, weight, function(err, result) { 	console.log(err, result); });

Broadcast Vote with Promises

var steem = require('steem');
var wif = steem.auth.toWif(username, password, 'posting'); // Using Promises steem.broadcast.vote(wif, voter, author, permlink, weight)   .then(result => console.log(result))   .catch(error => console.error(error));
// Or using async/await async function castVote() {   try {     const result = await steem.broadcast.vote(wif, voter, author, permlink, weight);     console.log(result);   } catch (error) {     console.error(error);   } }

Get Accounts

steem.api.getAccounts(['ned', 'dan'], function(err, result) {
	console.log(err, result);
});

Get State

steem.api.getState('/trends/funny', function(err, result) {
	console.log(err, result);
});

Reputation Formatter

var reputation = steem.formatter.reputation(user.reputation);
console.log(reputation);

Steem Testnet

Steem-js requires some configuration to work on the public Steem testnet.

You need to set two Steem API options, addressprefix and chainid.

steem.api.setOptions({   address_prefix: 'TST',   chain_id: '46d82ab7d8db682eb1959aed0ada039a6d49afa1602491f93dde9cac3e8e6c32',   useTestNet: true, });

The Chain ID could change. If it does, it may not be reflected here, but will be documented on any testnet launch announcements.
