Build Generative AI App with Next.js 14: Full Tutorial

In this comprehensive tutorial, Sonny Sangha demonstrates how to build a StoryTeller AI App from scratch using the latest Next.js 14. The app leverages GPTScript to create an AI Agent capable of chaining AI tasks together, resulting in a fully automated process for generating children’s storybooks with text and images based on a single prompt.

The tutorial covers a wide range of topics, including:
1. Implementing GPTScript to create an AI Agent that writes and illustrates stories.
2. Building API routes using Next.js’s app router Route Handler syntax.
3. Implementing streaming to stream the AI Agent’s processes in real-time from the API endpoint.
4. Utilizing caching in Next.js for an optimal and efficient user experience.
5. Using Next.js Server Components and Client Components appropriately.
6. Integrating OpenAI into the build.
7. Creating a beautiful UI and UX using Shadcn and Tailwind CSS.
8. Using TypeScript to reduce bugs and errors.
9. Deploying the final build on Vercel.

The video starts with an introduction and a demo of the StoryTeller AI App, showcasing its fully responsive design. Sonny explains the concept of AI agents and how they can autonomously combine different tools to perform tasks. The tutorial then dives into the technical setup, including initializing the build, creating the header component, and implementing Shadcn/ui for UI components.

Sonny demonstrates how to build the home page, the story writer component, and the AI terminal viewer, which displays the AI Agent’s real-time process. He explains how to create API endpoints and set up GPTScript, followed by implementing streaming functionality to provide a live update of the AI Agent’s progress.

The tutorial also covers fetching and displaying all previously created stories, building the stories page, and creating a storybook carousel view. Sonny adds toast notifications for better user feedback and concludes with a final build demo and deployment on Vercel.

Throughout the video, Sonny emphasizes the importance of clean code, efficient design, and leveraging AI to enhance the development process. He encourages viewers to join his developer community and course, Zero to Full Stack Hero, for more in-depth learning and support.

Overall, the tutorial provides a detailed and practical guide to building a generative AI app, showcasing the power of AI agents and modern web development tools.
