AI Form Builder Application Lecture Notes

Overview

• Developing an application that can generate forms using AI
• Creation of an admin dashboard for tracking forms and results
• Settings page for managing subscriptions
• Deployment and adding analytics using Drizzle ORM

Key Features

1. Form Generation using AI:

   • Users describe the form they need via a text area.
   • Sends a request to OpenAI API to generate form content.
   • Parses response to create a publishable and shareable form.

2. Admin Dashboard:

   • Track existing forms and create new ones.
   • View the results of forms.
   • Settings Page to manage subscriptions:
     • Free plans can create up to three forms.
     • Option to upgrade to a premium plan for more forms.

3. Deployment and Analytics:

   • Deploy the application.
   • Add analytics to track usage and custom events.

Tools and Libraries

• Next.js: Project setup with TypeScript, Tailwind CSS, Source directory, and app router.
• OpenAI API: For generating form content.
• Drizzle ORM: Interacting with the database.
• ShadCN: UI component library used within the application.
• Stripe: For managing subscriptions and payments.
• Plausible Analytics: For tracking user interactions and page views.

Technical Steps and Implementation

Project Setup

• Selected configuration options: TypeScript, ESLint, Tailwind CSS.
• Added ShadCN UI library and configured with TypeScript and Tailwind CSS.
• Set up global CSS and customized theme.
• Created initial components and setup file structure.

Form Generation Feature

• Popup with text area for form description.
• On submit, make API call to OpenAI to generate form content.
• Parse response and construct a form to be shared.
• Added integration with OpenAI API and handling parsing.

Admin Dashboard
