Quick Start

1. Preparation

First, require() the package:

const vk = require('vk-chat-bot');

Then, create your bot using the vk.bot function (see Params object for more information about params):

const params = {
  vkToken: 'your_vk_access_token',
  confirmationToken: 'f123456',
  groupId: 1234567,
  secret: 's3r10us1y_s3cr3t_phr4s3',
  port: 12345,

  cmdPrefix: '/'
};

var { bot, core } = vk.bot(params);

2. Behavior setup

See Core wiki to learn more about behavior functions. Here are some examples:

// Use stuff from the package...
const { Color, button, Keyboard } = vk.kbd;

// ...to create a keyboard like this.
// +-----------+---------+----------+----------+
// | Secondary | Primary | Negative | Positive |
// +-----------+---------+----------+----------+
// |      Maximum rows is 10, columns - 4.     |
// +-------------------------------------------+
var kbd = new Keyboard([
  [ /* Row (array of buttons) */
    button.text('Secondary'),
    button.text('Primary', Color.Primary),
    button.text('Negative', Color.Negative),
    button.text('Positive', Color.Positive)
  ],
  [
    button.text('Maximum rows is 10, columns - 4.')
  ],
]);

// When user presses the `Start` button...
// (you have to enable the button in community settings)
core.on('start', $ => {
  // ...send them our keyboard.
  $.text('Thanks for messaging us! Choose from the options below:');
  $.keyboard(kbd);

  // Here, $.send() is added automatically.
});

// Searches for cmd_prefix + 'help', e.g. '/help'
core.cmd('help', $ => {
  // core.help() returns the help message
  $.text('Test Bot v1.0' + core.help());

  // Attach an image from
  // https://vk.com/team?z=photo6492_45624077
  $.attach('photo', 6492, 456240778);
}, 'shows the help message');

// Use case-insensitive regular expression to find words 'hi', 'hello' or 'hey'
core.regex(/h(i|ello|ey)/i, $ => {
  $.text('Hello, I am a test bot. You said: ' + $.msg);
});

3. Start it!

Start the bot:

bot.start();

The bot will log some useful information, see Logging documentation for more information.
