nightmare-google-oauth2

Nightmare plugin to automatically authenticate, authorize and retrieve a fresh OAuth2 token ready to be used with Google APIs.

This package was designed to simplify server-to-server tasks automation and avoid headaches when dealing with OAuth, since it is the unique method to perform most of the user-related write operations via Google APIs, such as creating a post in Blogspot or uploading a video to YouTube

It provides reliable programmatic interface which abstracts you about performing any kind of manual steps related to the authentication, authorization and handshake process to obtain a valid OAuth2 token, which is usually done manually from the user in the web browser. It support multiple associated Google accounts as well, selecting the desired one

For nightware-agnostic interface and command-line solution, see google-oauth2-token.

Installation

npm install nightmare-google-oauth2 --save

Google API credentials setup

Be sure you have a project and a Web Application credentials with a Client ID and Client Secret from the Google API Console > API & Auth > Credentials

Then you must add the following URI as allowed redirects (without final slash):

http://localhost:8488

Then you should see something like this:

Programmatic API

var Nightmare = require('nightmare')
var NightmareOAuth2 = require('nightmare-google-oauth2')

Supported params

• email - Google Account user email. Example: [email protected]
• password - Google Account user password. Be aware with this. Use a temporal environment variable to store it
• clientId - Google API Client ID. You can obtain it from the Google API Console
• clientSecret - Google API Client Secret ID. You can obtain it from the Google API Console
• scope - Scope permissions URLs separated by spaces. Read more here
• useAccount - In case of multiple associated Google accounts, define the email of the desired account to use
• verificationEmail - In case that Google asks for the verification email. Not too common anyway.

.getToken(params, callback [, onChange ])

Return an object with valid OAuth2 tokens ready to be used to call Google APIs endpoints

{ 
  access_token: 'H3l5321N123sdI4HLY/RF39FjrCRF39FjrCRF39FjrCRF39FjrC_RF39FjrCRF39FjrC',
  token_type: 'Bearer',
  refresh_token: '1/smWJksmWJksmWJksmWJksmWJk_smWJksmWJksmWJksmWJksmWJk',
  expiry_date: 1425333671141 
}

Required params:

• email
• password
• clientId
• clientSecret
• scope

Example:

var params = {
  email: '[email protected]',
  password: 'sup3r_p@s$w0rd',
  clientId: 'blablabla', // Google API Client ID
  clientSecret: 'private', // Google API Client Secret
  scope: 'https://www.googleapis.com/auth/youtube.upload'
}

new Nightmare()
  .use(NightmareOAuth2.getToken(params, function (err, tokens) {
    if (err) {
      return console.error('Cannot retrieve the token:', err)
    }

    console.log('OAuth2 access token:', tokens.access_token)
    console.log('OAuth2 refresh token:', tokens.refresh_token)
    console.log('OAuth2 token expiry date:', new Date(tokens.expiry_date))
  }))

.getCode(params, callback)

Return an string with the OAuth2 exchange code to be used during the OAuth2 handshake to obtain a valid token. This process is implicitly made when calling getToken()

Required params:

• email
• password
• clientId
• scope

Example:

var params = {
  email: '[email protected]',
  password: 'sup3r_p@s$w0rd',
  clientId: 'blablabla', // Google API Client ID
  scope: 'https://www.googleapis.com/auth/youtube.upload'
}

new Nightmare()
  .use(NightmareOAuth2.getCode(params, function (err, code) {
    if (err) {
      return console.error('Cannot retrieve the token:', err)
    }

    console.log('OAuth2 code:', code)
  }))
