RAG (Retrieval-Augmented Generation) Boilerplate [Frontend + Backend]

Save hours of development time with this fully functional RAG boilerplate for modern web applications. Built with a ready-to-use Next.js frontend and FastAPI backend, this boilerplate integrates seamlessly with Chroma vector databases, APIs (GEMINI), making it the perfect starting point for developers, startups, or indie hackers building AI-powered apps.

What’s Included:

• Frontend: Modern, clean UI ready to plug in your RAG queries (Next.js).
• Backend: Preconfigured FastAPI (Python) server with embedding and retrieval logic.
• Easy Setup: Step-by-step instructions to get your RAG app running in minutes.
• Documentation: Complete video tutorial on how to use the boilerplate.
• Scalable Architecture: Designed for adding new features or models easily.

What Is Its Usage?

This boilerplate lets you upload a PDF and interact with it using AI — just like “Chat with your PDF.”
Here’s how you can use it:

• Upload a PDF document (e.g., research paper, book, report).
• Ask any question about the uploaded file — the AI retrieves relevant information using embeddings and responds intelligently.
• Ideal for building tools like:
  • “Chat with PDF” web apps
  • AI-powered document assistants
  • Knowledge retrieval bots for businesses
  • Research or study companions for students

Basically, this setup helps you talk with your data in a natural and intelligent way — all powered by RAG.

Who This Is For:

• Indie developers looking to kickstart AI projects.
• Startups needing a fast prototype for RAG-based apps.
• Hobbyists or students who want a hands-on learning project with modern AI tools.

Why Choose This Boilerplate:

• Save days of setup and avoid common pitfalls.
• Fully functional end-to-end RAG architecture ready for customization.
• Professional coding standards and clear documentation for faster development.
• Fully customizable – use, modify, and reuse this boilerplate for personal or commercial development.

Prerequisites:

Before using this boilerplate, make sure you have the following installed:

• IDE (e.g., VS Code, Cursor) for editing code.
• Node.js – required to run the Next.js frontend.
• Python – required to run the FastAPI backend.

⚠️ Optional but recommended: Basic knowledge of JavaScript/Node.js and Python/FastAPI will help you customize and extend the boilerplate.

⚠️ Limitations

• No chat history: Only one message/response shown at a time; past interactions aren’t saved. Means no previous memory.
• No authentication: Access is based on username only; no login/auth.
• File support: PDF files only; other formats not supported yet.

These areas can be extended with custom development. 😊
