VK Auth

Description

This module for Express.js will help you get server VK access token. After that you can use it to create your authentication system which uses VK. After gaining access token you can use it in other VK API modules. You can also easily get OAuth URL based on your settings with handy getUrl() method.

Installation

Just run npm install vkauth --save.

Configuring

Example of using:

var vkauth = require('./vkauth');
vkauth.config.client_id = Number(process.env['VK_CLIENT_ID']);
vkauth.config.app_secret = process.env['VK_APP_SECRET'];
vkauth.config.host = 'localhost:3000';
vkauth.config.route = '/token';
vkauth.config.scope = ['friends'];

Description:

• client_id - Client Id of your app;
• app_secret - Secret key of your app;
• host - Host of your application;
• route - Route where you want to get access token;
• scope - Array of permissions of your app.

You also can specify version of API using v property. Set it as String.

Using

Example:

vkauth.start(app, function(res, err, token) {
    if (err) {
        console.log(err);
    } else {
        console.log(token);
        res.json(token);
    }
});

• app - Express.js instance;
• res - Response object;
• err - Error, will be null if there is no error;
• token - access_token object, will be null, if there is an error.

token object:

• token.access_token - access token;
• token.user_id - user id;
• token.expires_in - expiration time in seconds.

You can get VK API URL based on config object using method vkauth.getUrl().
