promise-vksdk

Small SDK for vk.com API.

This is form of vksdk, with Promise

Installation

npm install promise-vksdk

Example

// Setup
var VK = require('promise-vksdk');
var vk = new VK({
   'appId'     : 2807970,
   'appSecret' : 'L14ZKpgQPalJdumI6vFK',
   'language'  : 'ru'
});

/**
 * Request server methods
 */

// Setup server access token for server API methods
vk.on('serverTokenReady', function(_o) {
    // Here will be server access token
    vk.setToken(_o.access_token);
});

// Turn on requests with access tokens
vk.setSecureRequests(true);

// Request server API method
let vksdk = require('promise-vksdk');
const vk = new vksdk({
   'appId'     : 2807970,
   'appSecret' : 'L14ZKpgQPalJdumI6vFK',
   'lang'  : 'ru'
});

vk.request("users.get", {user_id:1}).then(o=>console.log(o));

/**
 * Request client methods
 */
// First you have to pass access_token from client side JS code
vk.setToken(access_token);

// Request 'users.get' method
vk.request("users.get", {user_id:1}).then(o=>console.log(o));

Setup

var VK = require('promise-vksdk');

var vk = new VK({
    'appId'     : [Your application ID here],
    'appSecret' : [Your application secret code here],
});

Required config options:

• appSecret — application secret code (check your application settings on vk.com)
• appId — vk.com application id

Available config options:

• [bool] https — with this options all links in API answers will be with https protocol. Disabled by default.
• [string] version — vk.com api verions. Default: 5.27
• [string] language — Language code for api answers (for old deprecated API)
• [bool] secure — enable api requests with tokens. Default false.

You can read and change some config options:

• getVersion() — get current API version
• setVersion(_v) — set current API version
• getLanguage() — get current API language
• setLanguage(_v) — set current API language
• getHttps() — get https links usage for API answers
• setHttps(_v) — set https links usage for API answers
• getSecureRequests() — get token's usage for API requests
• setSecureRequests(_v) — set token's usage for API requests

API requests

For vk.com API requests you have to use method request(_method, _requestParams, _response).

• [string] _method — name of vk.com API method,
• [mixed] _requestParams - object with values of params for api method. This param is not required. You also can pass empty object {}
• [mixed] _response — special response handler (not required), function or event name. Request method gets data from API and returns result. There are 3 ways to get data from API

Callback

vk.setSecureRequests(false);
vk.request('users.get', {'user_id' : 1}, function(_o) {
console.log(_o);
});

Event

After success API call SDK emits the event named 'done:' + _method; So if you call method users.get, you have to wait event done:users.get

vk.setSecureRequests(false);
vk.request('users.get', {'user_id' : 1});
vk.on('done:users.get', function(_o) {
    console.log(_o);
});

Custom event

Result of request will be returned with your custom event

vk.setSecureRequests(false);
vk.request('users.get', {'user_id' : 1}, 'myCustomEvent');
vk.on('myCustomEvent', function(_o) {
    console.log(_o);
});

Server access token

For some api methods you need server access token

vk.requestServerToken();

// Waiting for special 'serverTokenReady' event
vk.on('serverTokenReady', function(_o) {
    // Here will be server access token
    console.log(_o);
});

You also can get token with callback or custom event #Errors:

vk.request("users.get", {user_id:1}).then(o=>console.log(o)).catch(err=>console.error(err));

HTTP errors

SDK emits 'http-error' event in case of http errors.

vk.on('http-error', function(_e) {
    console.log(_e);
});

JSON parsing errors

SDK emits 'parse-error' event in case of non-valid API answer.

vk.on('parse-error', function(_e) {
    console.log(_e);
});

SDK provides all methods from events.EventEmitter

Bonus

You also can request some api methods without any tokens, with app signature

vk.oldRequest('places.getCountryById', {'cids' : '1,2'}, function(_o) {
    console.log(_o);
});

But this way is deprecated and doesn't work for all api methods.

For developers
