Example of usage

Preparation

var vk = require('vk-sdk');

vk.setToken(/* access_token */);

Simple request

vk.callMethod('users.get', {
    uids: [1, 5]
})
    .then(function (response) {
        console.log('Success: ' + JSON.stringify(response));
        // Success: [{"uid":1,"first_name":"Pavel","last_name":"Durov"},{"uid":5,"first_name":"Ilya","last_name":"Perekopsky"}]
    })
    .catch(function (error) {
        console.log('Fail: ' + JSON.stringify(error));
    });

Grouping several requests to a single

There are two calls of the execute method in the snippet below, so only two request would be sent in fact.

vk.appendCall('users.get', {uid: 1})
    .then(function (response) {
        console.log(JSON.stringify(response));
    })
    .catch(onError);

vk.appendCall('friends.get', {uid: 1})
    .then(function (response) {
        console.log("\nFriends list: ", JSON.stringify(response));
    })
    .catch(onError);

vk.appendCall('wall.get', {owner_id: 1})
    .then(function (response) {
        console.log("\nWall posts: ", JSON.stringify(response));
    })
    .catch(onError);

vk.execute();


vk.appendCall('users.get')
    .then(function (response) {
        console.log(JSON.stringify(response));
    })
    .catch(onError);

vk.appendCall('friends.get')
    .then(function (response) {
        console.log("\nFriends list: ", JSON.stringify(response));
    })
    .catch(onError);

vk.appendCall('photos.getAlbums')
    .then(function (response) {
        console.log("\nAlbums list: ", JSON.stringify(response));
    })
    .catch(onError);

vk.execute();

function onError (error) {
    console.log(JSON.stringify(error));
}
