nyrag 0.0.3

nyrag

nyrag

A simple tool for building RAG applications by crawling websites or processing documents, then deploying to Vespa for semantic search with an integrated chat UI.

Installation

pip install nyrag

For development:

git clone https://github.com/abhishekkrthakur/nyrag.git
cd nyrag
pip install -e .

Quick Start

nyrag operates in two deployment modes (Local or Cloud) and two data modes (Web or Docs):

Deployment	Data Mode	Description
Local	Web	Crawl websites → Local Vespa Docker
Local	Docs	Process documents → Local Vespa Docker
Cloud	Web	Crawl websites → Vespa Cloud
Cloud	Docs	Process documents → Vespa Cloud

---

Local Mode

Runs Vespa in a local Docker container. Great for development and testing.

Web Crawling (Local)

export NYRAG_LOCAL=1

nyrag --config configs/example.yml

Example config for web crawling:

name: mywebsite
mode: web
start_loc: https://example.com/
exclude:
  - https://example.com/admin/*
  - https://example.com/private/*

crawl_params:
  respect_robots_txt: true
  follow_subdomains: true
  user_agent_type: chrome

rag_params:
  embedding_model: sentence-transformers/all-MiniLM-L6-v2
  chunk_size: 1024
  chunk_overlap: 50

Document Processing (Local)

export NYRAG_LOCAL=1

nyrag --config configs/doc_example.yml

Example config for document processing:

name: mydocs
mode: docs
start_loc: /path/to/documents/
exclude:
  - "*.csv"

doc_params:
  recursive: true
  file_extensions:
    - .pdf
    - .docx
    - .txt
    - .md

rag_params:
  embedding_model: sentence-transformers/all-mpnet-base-v2
  chunk_size: 512
  chunk_overlap: 50

Chat UI (Local)

After crawling/processing is complete:

export NYRAG_CONFIG=configs/example.yml
export OPENROUTER_API_KEY=your-api-key
export OPENROUTER_MODEL=openai/gpt-5.1

uvicorn nyrag.api:app --host 0.0.0.0 --port 8000

Open http://localhost:8000/chat

---

Cloud Mode

Deploys to Vespa Cloud for production use.

Web Crawling (Cloud)

export NYRAG_LOCAL=0
export VESPA_CLOUD_TENANT=your-tenant

nyrag --config configs/example.yml

Document Processing (Cloud)

export NYRAG_LOCAL=0
export VESPA_CLOUD_TENANT=your-tenant

nyrag --config configs/doc_example.yml

Chat UI (Cloud)

After crawling/processing is complete:

export NYRAG_CONFIG=configs/example.yml
export VESPA_URL="https://<your-endpoint>.z.vespa-app.cloud"
export OPENROUTER_API_KEY=your-api-key
export OPENROUTER_MODEL=openai/gpt-5.1

uvicorn nyrag.api:app --host 0.0.0.0 --port 8000

Open http://localhost:8000/chat
