Using API key with node js google library

Question

I am trying to consume google youtube data apis which has support for api key type of credentials.

https://developers.google.com/youtube/registering_an_application

I am trying to use google auth library for node js to communicate with the apis

https://github.com/googleapis/google-auth-library-nodejs

There is an example of this API with oAuth credentials and service account credentials.

I know that api key is supposed to be used by client side applications like browser based javascripts. So i see example with browser based google apis.

But is there any example where api keys can be used with google node js client library ?

Best Regards,

You can use Google API NodeJS client using an API key on NodeJS. Just put the API key instead of the oauth client in the auth field :

"use strict"

const {google} = require('googleapis');

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

youtube.search.list({
    part: 'id,snippet',
    q: 'Node.js on Google Cloud',
}).then(res => {
    console.log(res.data);
})
.catch(error => {
    console.error(error);
});;

There is this internal check in google-api-commons nodejs library which check if auth is a string and add the API key to the request in that case.
