VK API SDK for Node.js

Installation

To install the stable version:

npm install --save node-vk-sdk

This assumes you are using npm as your package manager. If you don’t, you can access these files on unpkg, download them, or point your package manager to them.

Importing

You can import SDK using ES6 modules:

import {VKApi, ConsoleLogger} from 'node-vk-sdk'

Or using require:

const {VKApi, ConsoleLogger} = require('node-vk-sdk')

Usage

import {VKApi, ConsoleLogger} from 'node-vk-sdk'

let api = new VKApi({
    logger: new ConsoleLogger()
})

api.usersGet({ userIds: ['1'] })
    .then(response => {
        console.log(response)
    })

VKApi constructor options

interface VKApiOptions {
    lang?: string|number,
    testMode?: number,
    logger?: BaseLogger,
    token?: string,
    timeout?: number,
    requestsPerSecond?: number,
    useQueue?: boolean
}

• lang? - Determines the language for the data to be displayed on. For example country and city names. If you use a non-cyrillic language, cyrillic symbols will be transtiterated automatically
  en – English, ru – Russian, ua – Ukrainian, be – Belorussian, es – Spanish, fi – finnish, de – German, it – Italian.
  Numeric format from account.getInfo is supported as well.

• test_mode? - 1 – allows to send requests from a native app without switching it on for all users.

• logger? - Logger class that implements BaseLogger No logging will be used logger is not passed

• token? - Access token

• timeout? - Network timeout in ms

• requestsPerSecond - Maximum requests per second, default is 3

• useQueue - If useQueue is true, then SDK will limit number of requests per second at requestsPerSecond

Calling methods

All api methods returning Promise, so you can use them as Promise or as async functions. Methods arguments are described in interfaces, so you need to pass object implementing that interface, for example users.get props interface:

export interface UsersGetParams {
    /**
     * User IDs or screen names ('screen_name'). By default, current user ID.
     */
    user_ids?: string[],
    /**
     * Profile fields to return. Sample values: 'nickname', 'screen_name', 'sex', 'bdate' (birthdate), 'city', 'country', 'timezone', 'photo', 'photo_medium', 'photo_big', 'has_mobile', 'contacts', 'education', 'online', 'counters', 'relation', 'last_seen', 'activity', 'can_write_private_message', 'can_see_all_posts', 'can_post', 'universities',
     */
    fields?: string[],
    /**
     * Case for declension of user name and surname: 'nom' — nominative (default), 'gen' — genitive , 'dat' — dative, 'acc' — accusative , 'ins' — instrumental , 'abl' — prepositional
     */
    name_case?: string,
    /**
     * access token
     */
    access_token?: string
}

All props interfaces have accessToken property, that token will be used instead of token passed to VKApi

Calling example:

api.usersGet({ user_ids: ['1'] })
    .then(response => {
        console.log(response)
    })

// or we can call it as async function

let response = await api.usersGet({ user_ids: ['1'] })

Direct call methods:

// makes plain call & returns contents of "response" property of server response
public async call(method: string, params: Object): Promise<any>

// Makes api call and if there was
// server-side error or requests limit was reached
// repeats the call after some timeout
public async callWithRetry(method: string, params: Object): Promise<any>

Bots Long Poll API

To receive group updates using Bots Long Poll API use BotsLongPollUpdatesProvider class:

import {VKApi, ConsoleLogger, BotsLongPollUpdatesProvider} from 'node-vk-sdk'

let api = new VKApi({
    token: 'GROUP_TOKEN_HERE',
    logger: new ConsoleLogger()
})

let updatesProvider = new BotsLongPollUpdatesProvider(api, GROUP_ID_HERE)

updatesProvider.getUpdates(updates => {
    console.log('got updates: ', updates)
})
