Usage

Iterating indefinitely over new blocks

import WorkerBee from "@hive/workerbee";

const bot = new WorkerBee();
bot.on("error", console.error);

await bot.start();

for await(const { block, number } of bot)
  console.info(`Got block #${block.block_id} (${number})`);

Wait for the next block using observer

import WorkerBee from "@hive/workerbee";

const bot = new WorkerBee();
bot.on("error", console.error);

await bot.start();

const block = await new Promise(blockResolve => {
  bot.once("block", blockResolve);
}); // Get one latest block

console.info(`Waiting for block: #${block.number + 1}`);
const observer = bot.observe.block(block.number + 1);

observer.subscribe({
  next() {
    console.info('Block detected');
  }
});

Observe given account for operations in blockchain

import WorkerBee from "@hive/workerbee";

const bot = new WorkerBee();
bot.on("error", console.error);

await bot.start();

const observer = bot.observe.accountOperations("gtg");

observer.subscribe({
  next(op) {
    console.info(op);
  }
});

Observe given account for full manabar regeneration

import WorkerBee from "@hive/workerbee";

const bot = new WorkerBee();
bot.on("error", console.error);

await bot.start();

const observer = bot.observe.accountFullManabar("gtg");

observer.subscribe({
  next(acc) {
    console.info(acc.voting_manabar); // { "current_mana": "0", "last_update_time": 0 }
  }
});

Broadcast and observe transaction in blockchain

import WorkerBee from "@hive/workerbee";
import beekeeperFactory from "@hive/beekeeper";

const beekeeper = await beekeeperFactory();
const session = await beekeeper.createSession("my.salt");
const { wallet } = await session.createWallet("w0", "mypassword");
await wallet.importKey("5JkFnXrLM2ap9t3AmAxBJvQHF7xSKtnTrCTginQCkhzU5S7ecPT");

const bot = new WorkerBee();
bot.on("error", console.error);

await bot.start();

// Build transaction
const builder = await bot.chain.getTransactionBuilder();
builder.push({
  vote: {
    voter: "otom",
    author: "c0ff33a",
    permlink: "ewxhnjbj",
    weight: 2200
  }
});

// Broadcast our transaction with custom internal expiration time
const observer = await bot.broadcast(builder.build(wallet, "5RqVBAVNp5ufMCetQtvLGLJo7unX9nyCBMMrTXRWQ9i1Zzzizh"));

// Observe if our transaction has been applied
observer.subscribe({
  next(tx) {
    console.info(tx, "applied in blockchain");
  },
  error() {
    console.error("Transaction observation time expired");
  }
});
