VkAuth

vk.com is not among standard auth providers in firebase, so we provide our own solution for this. To get acquainted with the flow, please, read this article.

In order to avoid creation of http server, vkAuthService works only with firebase and not with REST API. So, we strongly recommend to set redirect url to be a current location, thus one can get a token on a client side.

Internal work of a service one can found in source

Usage:

VkConfigService declaration

//vkAuthConfig.service.ts
import {Injectable} from "@angular/core";
import {VkAuthConfig, VkConfig, PopupConfig} from "@nodeart/firebase-connector";

@Injectable()
export class VkConfiguration implements VkAuthConfig {
    public vkConfig : VkConfig = {
        client_id: 'app_id',
        display: 'popup',
        scope: ['friends'],
        response_type: 'token',
        v: 5.63
    };
    public popupConfig: PopupConfig = {
        location: 'no',
        height: 600,
        width: 600
    };
    public cleanUp: boolean = true;
    public dbPath: string = 'auth/vk'; // #1 note that this field should be the same on server and client side #2;
    constructor() { }
}

VkConfigService register

//someModule.module.ts
import {NgModule} from "@angular/core";
import {VkConfiguration} from "./vkAuthConfig.service";
@NgModule({
  providers: [
    {provide: 'VkAuthConfig', useClass: VkConfiguration}
  ]
})
export class SomeModule { }

Server side or firebase cloud functions code:

'use strict';

const admin = require('firebase-admin');
// #2 note that this field should be the same on server and client side #1;
const authWithVk = admin.database().ref('auth/vk'); 

const listener = (ref, snapshot) => {
  const key = snapshot.key,
        val = snapshot.val();
        
  if (!val.processed) {
    admin.auth()
        .createCustomToken(val['access_token'])
        .then(token => {
          const data = Object.assign(val, {
            access_token: token,
            expires_in: null,
            processed: true
          });
          ref.child(key).set(data);
          return data
        })
        .then(data => console.log(`custom token generated = ${JSON.stringify(data)}`))
  }
};

authWithVk.on('child_added', snapshot => listener(authWithVk, snapshot));
