Build an AI Content Generator with React and Next.js (2024 Guide)

In this comprehensive guide, we’ll walk through building a full-stack AI content generator application from scratch using React, Next.js, Tailwind CSS, and more. We’ll explore a variety of technologies and how they come together to create a powerful tool. An accompanying video walks through the full process.

This project utilizes Next.js for the React framework, Tailwind CSS for styling, and the Gemini API (Google’s AI model) for content generation. Data storage is handled with PostgreSQL and Drizzle ORM. Clerk authentication manages user accounts. The application features a landing page, a template-driven content generation dashboard, a history tab, and a payment gateway integration for premium features. This guide covers all the steps needed to build a functional AI content generator.

Application Overview

Our AI content generator application starts with a clean and inviting landing page. Users can easily get started with social authentication provided by Clerk. Once logged in, a side navigation bar provides access to the main features. A credit user status is displayed, showing how much of their allotted content generation credit they’ve used.

The heart of the application is the dashboard, which offers a range of templates for generating various types of content. These templates are designed to be flexible and adaptable to specific user needs. A search option allows users to quickly find the template they need.

Content Generation in Action

Let’s see the content generation in action. Select a template, such as the code generation template, and provide a description of the desired output. For example, you might request a "bubble sort algorithm in React." The application then uses the Gemini API to generate the content.

Within seconds, the AI generates comprehensive content, including the code itself, a step-by-step explanation, and example output. The application dynamically updates the user’s credit status in real-time with each generation.

History and Account Management

The application keeps a detailed history of all generated content. Users can revisit their past creations, copy content, and review all the related information. This ensures that no work is ever lost.

To provide more value, the application includes a billing section where users can subscribe to a monthly membership and increase their content generation credit. The application integrates with a payment gateway like Reser Pay to handle subscriptions. User profile settings, managed with Clerk, allow users to control their account information.

Key Technologies

Several technologies are used to build this application:

• Next.js: A React framework for building web applications.
• Tailwind CSS: A utility-first CSS framework for styling.
• Gemini API: Google’s AI model for content generation.
• PostgreSQL: A relational database for data storage.
• Drizzle ORM: A TypeScript ORM for interacting with the database.
• Clerk: A user authentication service.

Building the Application: A Step-by-Step Guide

We’ll now delve into the key aspects of building the application.

Setting Up the Development Environment

To begin, you’ll need to set up your development environment with Node.js and a suitable code editor. Create a new Next.js project using create-next-app. Install Tailwind CSS and configure it for your project.

Integrating Clerk Authentication

Clerk simplifies user authentication. Create a Clerk application and obtain your API keys. Install the Clerk React package and wrap your application with the <ClerkProvider> component. Use Clerk’s pre-built components for sign-in, sign-up, and user profile management.

Connecting to the Gemini API

To use the Gemini API, you’ll need to create a Google Cloud project and enable the Gemini API. Obtain an API key and install the necessary client libraries. Create functions to send requests to the API and process the responses. Remember that while the Gemini API offers a free tier, usage is subject to Google’s terms and conditions.

Database Setup with PostgreSQL and Drizzle ORM

Set up a PostgreSQL database using a service like Neon, which offers a free tier. Install Drizzle ORM and create your database schema. Define your tables and relationships using Drizzle’s TypeScript syntax. Use Drizzle to perform database queries and mutations.

Building the User Interface with React and Tailwind CSS

Use React components to build the user interface. Tailwind CSS provides a wide range of utility classes to style your components. Create reusable components for common UI elements. Use Next.js’s routing capabilities to navigate between different pages.

Implementing the Content Generation Logic

Create functions to handle content generation requests. These functions should take user input, send it to the Gemini API, and process the response. Display the generated content in a user-friendly format.

Key Takeaways

• Next.js provides a robust framework for building full-stack React applications.
• Tailwind CSS simplifies styling and ensures a consistent look and feel.
• The Gemini API offers a powerful tool for generating various types of content.
• Clerk streamlines user authentication and account management.
• Drizzle ORM provides a type-safe way to interact with PostgreSQL databases.

Frequently Asked Questions

Is the Gemini API really free to use?

The Gemini API offers a free tier, but it’s important to check the usage limits and any applicable terms and conditions.

Do I need prior experience with all of these technologies?

While prior experience is helpful, this guide is designed to be beginner-friendly. You can learn as you go.

Can I use a different database instead of PostgreSQL?

Yes, you can use other databases, but you’ll need to adapt the Drizzle ORM configuration accordingly.

Is Clerk the only authentication provider I can use?

No, you can use other authentication providers, but Clerk is a convenient and easy-to-integrate option.

How can I customize the content generation templates?

You can customize the templates by modifying the prompts sent to the Gemini API.

Building an AI content generator application is a challenging but rewarding project. By combining the power of React, Next.js, Tailwind CSS, and the Gemini API, you can create a versatile tool that empowers users to generate high-quality content. Remember to carefully consider the API’s usage terms and conditions, and always prioritize user privacy and security. The technologies described here provide a solid base for content automation.
