nodeJS connection with Google API

Question

I am trying to connect hangouts chat API with NodeJS but did not find any documentation related to Oauth in NodeJS, without which I can not connect to APIs. There is a code in Python but is there any thing in Node so that we can do the API call from front end it self.

Answer 1

The Oauth flow is the same for all Google APIs

• If there is a quickstart for a specific API in a specific language missing, you can use one from another API.
• For example, there is a Node.js quickstart for the Drive API
• You can take it as a base and have to modify only 2 things:

1. Modify

   const SCOPES = ['https://www.googleapis.com/auth/drive.metadata.readonly'];

   by specifying the scopes you are going to use, for example

   https://www.googleapis.com/auth/chat

2. For building the service, modify

   const drive = google.drive({version: 'v3', auth});

   to

   const chat = google.chat({version: 'v1', auth});

• Mind that depending on the application, you might need to use a service account
• The documentaiton about implementing a service account in node.js can be found here
