Build a Ninja Player App with Next.js, NextAuth, Tailwind CSS, DaisyUI, and Firebase

Ready to build a cool application that lets users create posts and find players nearby? This article walks you through building a “Ninja Player” app using Next.js, NextAuth for authentication, Tailwind CSS and DaisyUI for styling, and Firebase for the database. An accompanying video walks through the full process.

This project combines the power of Next.js for routing and React components with the ease of Tailwind CSS and DaisyUI for styling. Google authentication is implemented using NextAuth, and Firebase provides a robust and free database solution. The application is fully responsive, allowing users to create posts, search for players by zip code or game, and manage their profiles. It’s a great way to learn modern web development techniques.

Setting Up Your Next.js Application

Next.js is a popular React framework known for its routing capabilities and performance. Let’s start by creating a new Next.js application. First, navigate to your desired project folder in your terminal. Then, use the following command to create a new Next.js app:

npx create-next-app

The command prompt will ask you to proceed. Type "yes" and press enter. You’ll then be prompted to enter a project name. In this case, let’s name our project "ninja-player".

npx create-next-app ninja-player

This command installs all the necessary dependencies, including React, React DOM, and Next.js. This process might take a few minutes.

Exploring the Project Structure

Once the installation is complete, navigate to your project folder by typing the following command:

cd ninja-player

Now that you are in the project folder, open the project in Visual Studio Code (or your preferred code editor) by typing:

code .

This command opens the current project in VS Code. Let’s take a look at the project structure:

• pages: This directory contains all the pages and routes for your Next.js application. Every file in this folder becomes a route.
• _app.js: This file is the entry point for your application. It’s where all your components are rendered.
• index.js: This is the default page for your Next.js application. It’s the first page users will see.
• public: This folder stores static assets like images.

It’s important to note that modifying the names of these folders could potentially affect the application’s functionality.

Implementing Google Authentication with NextAuth

Authentication is a critical component of many web applications. NextAuth simplifies the process of adding authentication to your Next.js app. We’ll focus on Google authentication in this project. First, you’ll need to install NextAuth.js.

After setting up NextAuth, you’ll need to configure a Google OAuth 2.0 application within the Google Cloud Console. This involves creating credentials and obtaining a Client ID and Client Secret. These credentials will be used to authenticate users through Google.

Once you have the Client ID and Client Secret, you’ll need to add them to your Next.js application’s environment variables. You’ll also configure the NextAuth API route within your pages/api directory to handle authentication callbacks and session management. This route will interact with the Google OAuth provider to authenticate users and manage their sessions.

Styling with Tailwind CSS and DaisyUI

Tailwind CSS is a utility-first CSS framework that allows you to rapidly style your application using pre-defined CSS classes. DaisyUI is a component library built on top of Tailwind CSS, providing pre-built components that you can easily customize.

To get started with Tailwind CSS and DaisyUI, you’ll need to install them as dependencies in your project. You’ll also need to configure your tailwind.config.js file to include DaisyUI as a plugin. This will allow you to use DaisyUI components in your application.

With Tailwind CSS and DaisyUI set up, you can start styling your application by adding Tailwind classes to your HTML elements. DaisyUI components provide pre-styled elements like buttons, cards, and modals that you can easily incorporate into your design.

Firebase as a Database

Firebase is a popular and free database solution that integrates seamlessly with Next.js applications. To use Firebase, you’ll need to create a new Firebase project in the Firebase console. Once you’ve created a project, you’ll need to configure it for web use and obtain your Firebase configuration credentials.

These credentials will include your API key, authentication domain, project ID, and other information needed to connect to your Firebase database. You’ll need to add these credentials to your Next.js application’s environment variables.

With Firebase configured, you can start reading and writing data to your database using the Firebase SDK. You can store user data, player information, and post details in Firebase collections.

Firebase provides real-time database capabilities, which means that any changes to your data will be instantly reflected in your application. This is useful for creating interactive and dynamic user experiences.

Building the User Interface

The user interface of the Ninja Player application includes several key components:

• Logo and Navigation: A clear logo and intuitive navigation help users easily understand and navigate the application.
• Search Functionality: Users can search for players by zip code or game type.
• Post Display: Relevant posts are displayed based on the search criteria.
• Post Details: Clicking on a post reveals detailed information, including contact information (email ID) of the poster.
• Profile Management: Users can manage their profiles, create new posts, and delete existing ones.

The application is designed to be mobile-friendly and responsive, adapting to different screen sizes. This ensures a consistent user experience across various devices.

Key Takeaways

Here are the key takeaways from building the Ninja Player application:

• Next.js Routing: Learn how to create pages and routes in Next.js.
• NextAuth Authentication: Implement Google authentication using NextAuth.
• Tailwind CSS and DaisyUI Styling: Style your application quickly and easily using Tailwind CSS and DaisyUI components.
• Firebase Database: Use Firebase to store and retrieve data in real-time.
• Responsive Design: Create a mobile-friendly and responsive user interface.
