How set API KEY in Google Translate Node.js code

I'm trying to create a Node.js code that uses Google Translate API. I got the code below from the Google doc

But when I run it, it says Error: The request is missing a valid API key. I have the key, but I don't know how and where to set it.

async function translate() { // Imports the Google Cloud client library
    const { Translate } = require('@google-cloud/translate');

    // Creates a client
    const translate = new Translate();

    /**
     * TODO(developer): Uncomment the following lines before running the sample.
     */
    const text = 'Hello, world!';
    const target = 'ru';

    // Translates the text into the target language. "text" can be a string for
    // translating a single piece of text, or an array of strings for translating
    // multiple texts.
    let [translations] = await translate.translate(text, target);
    translations = Array.isArray(translations) ? translations : [translations];
    console.log('Translations:');
    translations.forEach((translation, i) => {
        console.log(`${text[i]} => (${target}) ${translation}`);
    });
}
translate()

  1. create api-key see documentation create api key doc
  1. use it like:
import { v2 } from '@google-cloud/translate'; 
const translateClint = new v2.Translate({
    projectId:'your-projectId-here',
    key: 'your-api-key-here',
});

I don't check it for v3, but I see the same interface: new v3.TranslationServiceClient({ key:"may be works", projectId:"may be works" })

Try this... no environment variables AND please... add this file to your .gitignore

   import * as credentials from 'credentials.json'; 
...
    const {Translate} = require('@google-cloud/translate').v2;
    const translationApi = new Translate({
                    projectId:'your-project-id',
                    credentials:credentials
                });

This page on setting up authentication explains that you need to download a credentials file from the create service account key page. This can then be added to your path (.bashrc) as follows: 

export GOOGLE_APPLICATION_CREDENTIALS="[PATH]"

Alternately, you could add the line above to a .env file on your project root and source it when you are running the application:

. ./.env
npm start

or

sh -ac '. ./.env; npm start'

Checkout this Google Authentication Page to add the key

  1. In the GCP Console, go to the Create service account key page.

  2. From the Service account list, select New service account.

  3. In the Service account name field, enter a name.

  4. From the Role list, select Project > Owner. Click

  5. Create. A JSON file that contains your key downloads to your computer.

and

export GOOGLE_APPLICATION_CREDENTIALS="[PATH to key downloaded]"
