Connecting Google Cloud BigQuery with Node.js Using API Key

Google Cloud BigQuery is a powerful and scalable data warehouse that allows users to analyze large datasets in real-time. When working with Node.js, it's essential to establish a secure connection to BigQuery to leverage its capabilities in your applications. One of the authentication methods available is using an API key. In this guide, we'll walk through the steps to connect Google Cloud BigQuery with Node.js using an API key.

Prerequisites

Before you begin, ensure you have the following:

Google Cloud Platform Account: Create a Google Cloud Platform (GCP) account if you don't have one already.

Project Setup: Set up a project on GCP and enable the BigQuery API.

API Key: Generate an API key from the GCP Console.

Node.js: Install Node.js on your local machine.

Steps to Connect Google Cloud BigQuery with Node.js Using API Key

Step 1: Create a Google Cloud Platform Project

Log in to the Google Cloud Console.

Create a new project or select an existing one.

Step 2: Enable the BigQuery API

In the Cloud Console, navigate to the "APIs & Services" > "Dashboard."

Click on the "+ ENABLE APIS AND SERVICES" button.

Search for "BigQuery API" and enable it for your project.

Step 3: Generate an API Key

In the Cloud Console, go to "APIs & Services" > "Credentials."

Click on "Create credentials" and choose "API Key."

Restrict the API key for security purposes if necessary.

Step 4: Install the BigQuery Node.js Client Library

In your Node.js project, install the @google-cloud/bigquery library:
