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: john@gmail.com
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.

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

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)
