Using Firebase and Firestore in a Next.js Application: A Step-by-Step Tutorial

Using Firebase and Firestore with Next.js

Overview

In this tutorial, we will walk you through the process of integrating Firebase and Firestore into a Next.js application. By the end of this article, you’ll be able to fetch and post data to Firestore from your Next.js app. We will cover the following steps:

1. Installing and configuring Firebase using the modular SDK and environment variables
2. Creating an API endpoint for fetching data from Firebase
3. Creating an API endpoint for posting data to Firebase
4. Configuring Firebase Firestore to accept requests

Let’s dive into each step in detail.

Step 1: Install and Configure Firebase

First, you need to install the Firebase package and initialize your app. To do this, run the following command in your Next.js project:

npm install firebase

Next, create a .env.local file in your project's root directory, and add the necessary Firebase configuration values as environment variables. You should have received these values when you set up your Firebase project.
