If you encounter any difficulties, don’t hesitate to reach out to Brightside Digital for professional assistance.


Installation of Firebase: A Brief Introduction

Before deep-diving into the installation process, it’s crucial to understand what Firebase is. Firebase is a suite of tools and infrastructure developed by Google. It offers various services like Cloud Firestore, Firebase Storage, Firebase Realtime Database, Cloud Functions for Firebase, Firebase Cloud Messaging, and many more.

Installing Node.js: The Preliminary Step

The Firebase Command Line Interface (CLI) is built on Node.js. Therefore, setting up the Node.js environment is the first step towards installing the Firebase CLI. If Node.js is not installed in your system, consider doing it first. Node.js is an open-source, cross-platform, JavaScript runtime environment that executes JavaScript code outside a web browser.

How to Install Node.js?

To install Node.js, follow these simple steps:

  1. Download the Node.js source code or a pre-built installer for your platform from the official Node.js download page.
  2. Run the installer and follow the prompts in the installation wizard.

Now, you are ready to install Firebase CLI.

Installation of Firebase CLI: The Key Step

The Firebase CLI is a command-line tool that allows you to create, manage, view, and deploy to Firebase projects directly from your system’s terminal. This tool provides a wide array of functions. Apart from managing and viewing Firebase projects, it’s also used for deploying Firebase Cloud Functions.

To install the Firebase CLI, you need to install the Firebase Tools package. The Firebase Tools package can be installed using the Node Package Manager (npm), a package manager for the JavaScript programming language.

How to Install Firebase CLI?

The Firebase CLI can be installed using the following npm command:

npm install -g firebase-tools

On certain platforms like macOS and Linux, you might need superuser privileges to execute the command:

sudo npm install -g firebase-tools

Logging into Firebase: Establishing the Connection

After installing Firebase CLI, the next step is to log into Firebase using the same Google account that you use to access the Firebase console. The Firebase CLI tool provides a command to log into Firebase:

firebase login

This command opens a browser window for you to select the Google account associated with your Firebase projects. Once the login is successful, you can return to the terminal or command prompt window. To log out at any point, you can use the following command:

firebase logout

Creating a Firebase Cloud Functions Project: Getting Started

The Firebase CLI tool is also used to create new Firebase Cloud Functions projects. To create a new project, you need to create a new directory in a suitable location on your filesystem. Change the directory to the new project folder and run the following command:

firebase init functions

The initialization command will guide you through the project setup. Select the Firebase project and agree to install the dependencies.

Reviewing the Firebase Cloud Functions Project: Understanding the Structure

Once the creation of the Firebase Cloud Functions project is complete, the project folder will contain various files and directories:

  • .firebaserc: This is a hidden file that helps the Firebase CLI to know about the project information.
  • firebase.json: This file is used to configure your project’s settings.
  • functions/package.json: This is a manifest file that handles the project’s dependencies.
  • functions/index.js: This file is where we will write Cloud Functions.
  • functions/node_modules: This directory contains the dependency packages defined in the package.json file.

Deploying a Simple HTTP Cloud Function: Seeing Firebase in Action

With Firebase installed and the project set up, it’s time to deploy a simple HTTP Cloud Function. This can be done by adding some code to the functions/index.js file and then deploying it using the Firebase CLI command:

firebase deploy --only functions:helloWorld

This command will deploy only the helloWorld function. To deploy all the functions in the index.js file, you can use the following command:

firebase deploy --only functions

Reviewing the Logs: Keeping Track of Activities

Firebase provides two ways to access the logs of your Cloud Functions – through the Firebase CLI and the Firebase console. To view the logs using the Firebase CLI, you can use the following command:

firebase functions:log

Alternatively, you can view the logs from the Firebase console by navigating to the Functions Dashboard of your project.

Removing a Deployed Function: Cleaning Up

If you decide to withdraw a Cloud Function from deployment, you can do so by either removing it from the index.js file or commenting it out. After doing so, run the Firebase CLI deployment command:

firebase deploy --only functions

Firebase will detect the absence of the previously deployed function and delete it from the cloud.
