Rag PROJECT01 Framework

Rag PROJECT01 Framework is a Python implementation of a retrieval-augmented generation system for knowledge-base question answering. It separates document chunking, text vectorization and storage, and similarity retrieval into modules that developers can inspect and customize, without relying on a heavyweight RAG framework.

Understand the project

Practical overview

When it fits

Use the project when you want a self-hosted implementation to study or customize the core document-to-retrieval stages of a knowledge-base Q&A workflow.

Who it is for

  • Developers building a self-hosted, document-grounded question-answering application.
  • Learners who want to examine the stages of a RAG pipeline in a hands-on project.
  • Developers prototyping retrieval workflows with adjustable document chunk sizes.

Documented uses

  • Turn a document collection into chunks suitable for retrieval.
  • Vectorize and store text chunks for similarity-based matching.
  • Build a customizable knowledge-base question-answering system.
  • Study or adapt RAG pipeline components without depending on a heavyweight RAG framework.
Before you choose

Requirements & limits

The repository is public and includes a Git clone command. No license is specified in the repository details; review licensing terms before reusing or distributing the code.

  • The project describes itself as an implementation from scratch rather than a wrapper around a heavyweight RAG framework.
  • Backend and frontend setup are separate, using Python with Uvicorn and Node.js with npm respectively.
  • Dependency instructions vary by operating system; the README notes a Windows-specific Milvus limitation and offers Docker or a Chroma branch as alternatives.
  • The setup describes API-key configuration and an optional local Hugging Face model path.

Check current requirements in the official documentation. Source-based guidance does not mean OpenViST has run or independently tested this project.

Source-based practical guide

Prepare the backend environment

Set up the documented Python environment, dependencies, model and API-key configuration, then start the backend with Uvicorn.

Before you start

  • A local clone of the repository
  • Miniconda and Python 3.11.9 as shown in the setup instructions
  • An operating-system-appropriate requirements file
  • OpenAI and/or DeepSeek API keys for the documented environment variables

Steps

  1. Create and activate a Conda environment named rag-project01 with Python 3.11.9.

  2. Install backend dependencies using the requirements file for the chosen platform; follow the separate Mac instructions where applicable.

  3. Optionally set HF_MODEL_PATH for a locally downloaded Hugging Face model, and configure OPENAI_API_KEY and DEEPSEEK_API_KEY in the shell profile.

  4. From the backend directory, start the app with Uvicorn using the README’s command: uvicorn main:app --reload --port 8001 --host 0.0.0.0.

Expected outcome

The documented backend setup culminates in a Uvicorn process serving the app on port 8001, provided the backend module and app instance match the README’s stated names.

Guide limitations

  • The README’s platform-specific dependency instructions differ; Windows users are told to use Docker for Milvus or switch to a Chroma branch.
  • A locally downloaded Hugging Face model is optional; the README also asks users to configure API-key environment variables.
  • The README says to choose another port if 8001 is occupied.

Source-based practical guide

Prepare and start the Ubuntu frontend

Install the frontend packages, configure the backend base URL and start the development frontend.

Before you start

  • A local clone of the repository
  • Ubuntu with Node.js and npm; the README notes Node.js v22.14.0 and npm 10.9.2

Steps

  1. Open the frontend directory and check npm with npm -v; install Node.js and npm through apt if needed.

  2. Run npm install in the frontend directory.

  3. Set apiBaseUrl in frontend/src/config/config.js to the intended backend address.

  4. Run npm run dev, or use the README’s documented mode argument to select another environment.

Expected outcome

The frontend development process starts with its API base URL configured to point at the chosen backend address.

Guide limitations

  • The guide documents frontend development startup, not a production deployment procedure.
  • The configured backend address must correspond to the backend setup in use.
