General Usage

Add 'zbc-sdk' packages to your project by executing:

$ npm install zbc-sdk
or
$ yarn add zbc-sdk

Here's an example of basic usage for connection:

import React, { useState, useEffect } from 'react';
import zoobc from 'zbc-sdk';

const App = () => {
  const [blocks, setBlocks] = useState([])
  const [error, setError] = useState(null)
  const [detail, setDetail] = useState(null)

  useEffect(() => {
    const hosts = [
      { host: 'http://your-ip-address:your-port', name: 'Testnet' },
    ];
    zoobc.Network.list(hosts)
    listBlocks();
  }, [])

  const listBlocks = () => {
    zoobc.Block
      .getBlocks({height: 0})
      .then(res => setBlocks(res.blocksList))
      .catch(err => setError(err))
  };

  const onClickBlockId = (id) => {
    zoobc.Block
      .getBlockById(id)
      .then(res => {
        setDetail(res)
        setError(null)
      })
      .catch(err => {
        setError(err)
        setDetail(null)
      })
  }

  const onClickBlockHeight = (height) => {
    zoobc.Block
      .getBlockByHeight(height)
      .then(res => {
        setDetail(res)
        setError(null)
      })
      .catch(err => {
        setError(err)
        setDetail(null)
      })
  }

  return (
    <>
      {!!error && (
        <>
          <div><strong>Error</strong></div>
          <code>{JSON.stringify(error)}</code>
        </>
      )}{!!detail && (
        <>
          <div><strong>Detail</strong></div>
          <code>{JSON.stringify(detail)}</code>
        </>
      )}
        <table>
          <thead>
            <tr>
              <th>Id</th>
              <th>Previous Hash</th>
              <th>Height</th>
              <th>Timestamp</th>
              <th>Version</th>
            </tr>
          </thead>
          <tbody>
            {blocks.length > 0 &&
              blocks.map((data, key) => {
                return (
                  <tr key={key}>
                    <td onClick={() => onClickBlockId(data.block.id)}>
                      {data.block.id}
                    </td>
                    <td>{data.block.previousblockhash}</td>
                    <td onClick={() => onClickBlockHeight(data.block.height)}>
                      {data.block.height}
                    </td>
                    <td>{data.block.timestamp}</td>
                    <td>{data.block.version}</td>
                  </tr>
                );
              })}
          </tbody>
        </table>
      </>

export default App;
