FireStore Database Setup

 In this post, I'm going to walk you through setting up Firebase and using Firestore to manage chat history in an AI application. Firebase is a powerful platform provided by Google, and one of its key features is Firestore, a cloud-based NoSQL database that's perfect for storing and syncing data in real-time. This is especially useful for chat applications where you need to keep track of conversations.

Why Use Firestore?

In my project, I'm using Firestore to store the chat history between the user and the AI. Here's why Firestore is a great choice:

  • Data Persistence: Firestore keeps the chat history safe, even if the app is closed. When the app is restarted, the previous conversation can be retrieved and continued seamlessly.
  • Real-Time Sync: Firestore automatically syncs data across devices, making sure that the chat history is always up-to-date.
  • Scalability: As my app grows and more users start using it, Firestore can handle the increase in data without any issues.

How to Set Up Firebase and Firestore

Let's go through the steps to set up Firebase and Firestore, and then integrate it into the application.

Step 1: Create a Firebase Account

  1. First, head over to Firebase’s website and click on "Get started."
  2. Sign in with your Google account. If you don't have a Google account yet, you'll need to create one.

Step 2: Create a New Firebase Project

  1. Once you're in the Firebase Console, click on "Add project" or "Create a project."
  2. Give your project a name that makes sense for what you're building. You can choose whether or not to enable Google Analytics for this project.
  3. After creating the project, make sure to note down the Project ID—you'll need it later when setting up Firestore.

Step 3: Set Up Firestore Database

  1. In the Firebase Console, select your project and go to "Firestore Database" from the menu on the left.
  2. Click "Create database" to start the setup process.
  3. Choose the database location that best fits your user base. Then, decide if you want to start in "Test mode" (which is good for development) or "Production mode" (which is more secure for live apps).

Step 4: Install the Google Cloud CLI

  1. To interact with Firestore from your local machine, you'll need the Google Cloud SDK, which includes the gcloud command-line tool. Follow the installation instructions provided here.
  2. After installing, authenticate the CLI by running the following command in your terminal or command prompt:

gbash 
gcloud auth login
      3. Once logged in, set your project as the default by running:
gbash 
gcloud config set project [YOUR_PROJECT_ID] 

Step 5: Enable Firestore API

  1. Now, you'll need to enable the Firestore API. Go to the Firestore API enablement page in the Google Cloud Console.
  2. Ensure that your project is selected (check the project name at the top of the page) and click "Enable" to activate the Firestore API.
