-# CLAUDE.md
-
-This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
-
-## Repository Overview
-
-Create-llama is a monorepo containing CLI tools and server frameworks for building LlamaIndex-powered applications. The repository combines TypeScript/Node.js and Python components in a unified development environment.
-
-## Architecture
-
-### Monorepo Structure
-
-- **`packages/create-llama/`**: Main CLI tool for scaffolding LlamaIndex applications
-- **`python/llama-index-server/`**: Python/FastAPI server framework
-- **Root**: Workspace configuration and shared development tools
-
-### Key Technologies
-
-- **Package Manager**: pnpm with workspace configuration
-- **Build Tools**: bunchee (TypeScript), Next.js, hatchling (Python)
-- **Testing**: Playwright for e2e, pytest for Python
-- **Version Management**: changesets for TypeScript packages, manual for Python
-
-## Development Commands
-
-### Root Level (Monorepo)
-
-```bash
-pnpm dev          # Start all packages in development mode
-pnpm build        # Build all packages
-pnpm lint         # ESLint across TypeScript packages
-pnpm format       # Prettier formatting
-pnpm e2e          # Run end-to-end tests
-```
-
-### Create-llama Package
-
-```bash
-cd packages/create-llama
-npm run build     # Build CLI using bash script and ncc
-npm run dev       # Watch mode development
-npm run e2e       # Playwright tests for generated projects
-npm run clean     # Clean build artifacts and template caches
-```
-
-### Python Server Package
-
-```bash
-cd python/llama-index-server
-uv run generate   # Index data files
-fastapi dev       # Start development server with hot reload
-pytest            # Run test suite
-```
-
-## Template System
-
-The CLI uses a sophisticated template system in `packages/create-llama/templates/`:
-
-### Organization
-
-- **`types/`**: Base project structures (streaming, reflex, llamaindexserver)
-- **`components/`**: Reusable components across frameworks
-  - `engines/` - Chat and agent engines
-  - `loaders/` - File, web, database loaders
-  - `providers/` - AI model configurations
-  - `vectordbs/` - Vector database integrations
-  - `use-cases/` - Workflow implementations
-
-### Development Workflow
-
-- Templates support multiple frameworks (Next.js, Express, FastAPI)
-- Component system allows mix-and-match functionality
-- E2E tests validate generated projects work correctly
-
-## Server Framework Architecture
-
-### Python Server (`llama-index-server`)
-
-- **Core**: `LlamaIndexServer` class extending FastAPI
-- **Architecture**: Workflow factory pattern for stateless request handling
-- **UI Generation**: AI-powered React component generation from Pydantic schemas
-- **Development**: Hot reloading support with dev mode
-
-## Common Patterns
-
-### Workflow Integration
-
-Both server frameworks use factory patterns:
-
-```typescript
-// TypeScript
-const server = new LlamaIndexServer({
-  workflow: (context) => createWorkflow(context)
-});
-
-// Python
-def create_workflow(chat_request: ChatRequest) -> Workflow:
-    return MyWorkflow(chat_request.messages)
-```
-
-### Event System
-
-Structured events for UI communication:
-
-- **UIEvent**: Custom components with Pydantic/Zod schemas
-- **ArtifactEvent**: Code/documents for Canvas panel
-- **SourceNodesEvent**: Document sources with metadata
-- **AgentRunEvent**: Tool usage and progress tracking
-
-### File Handling
-
-- Both servers auto-mount `data/` and `output/` directories
-- LlamaCloud integration for remote file access
-- Static file serving through framework-specific methods
-
-## Testing Strategy
-
-### E2E Testing
-
-- Playwright tests in `packages/create-llama/e2e/`
-- Tests both Python and TypeScript generated projects
-- Validates CLI generation and application functionality
-
-### Unit Testing
-
-- Python: pytest with comprehensive API and service tests
-- TypeScript: Integrated testing through build process
-
-## Build Process
-
-### Create-llama CLI
-
-1. TypeScript compilation with bash script
-2. ncc bundling for standalone executable
-3. Template validation and caching
-
-### Server Package Build
-
-1. **prebuild**: Clean directories
-2. **build**: bunchee compilation to ESM/CJS
-3. **postbuild**: Next.js preparation and static asset generation
-4. **prepare:py-static**: Python integration assets
-
-### Release Process
-
-```bash
-pnpm release     # Build all + publish npm packages + Python release
-```
-
-## Development Environment Setup
-
-### Prerequisites
-
-- Node.js >=16.14.0
-- Python with uv package manager
-- pnpm for package management
-
-### Common Workflow
-
-1. Clone repository and run `pnpm install`
-2. For CLI development: work in `packages/create-llama/`
-3. For server development: choose TypeScript or Python package
-4. Use `pnpm dev` for concurrent development across packages
-5. Run `pnpm e2e` to validate changes with generated projects
-
-## Special Considerations
-
-### Template Development
-
-- Changes to templates require rebuilding CLI
-- E2E tests validate template functionality across frameworks
-- Template caching system speeds up repeated builds
-
-### Cross-package Dependencies
-
-- Server package builds static assets for Python integration
-- Version synchronization between TypeScript and Python packages
-- Shared UI components and styling across implementations
-
-### Performance
-
-- CLI uses caching for template operations
-- Server frameworks support streaming responses
-- Background processing for file operations and LlamaCloud integration

-# Contributing
-
-## Getting Started
-
-Install NodeJS. Preferably v18 using nvm or n.
-
-Inside the `create-llama` directory:
-
-```
-npm i -g pnpm
-pnpm install
-```
-
-Note: we use pnpm in this repo, which has a lot of the same functionality and CLI options as npm but it does do some things better, like caching.
-
-### Building
-
-When we publish to NPM we will have a [ncc](https://github.com/vercel/ncc) compiled version of the tool. To run the build command, run
-
-```
-pnpm run build
-```
-
-### Test cases
-
-We are using a set of e2e tests to ensure that the tool works as expected.
-
-We're using [playwright](https://playwright.dev/) to run the tests.
-To install it, call:
-
-```
-pnpm exec playwright install --with-deps
-```
-
-Then you can create a global `create-llama` command (used by the e2e tests) that is linked to your local dev environment (if you update the build, you don't need to re-link):
-
-```
-pnpm link --global
-```
-
-And then finally run the tests:
-
-```
-pnpm run e2e
-```
-
-To write new test cases write them in [e2e](/e2e)
-
-## Changeset
-
-We use [changesets](https://github.com/changesets/changesets) for managing versions and changelogs. To create a new changeset, run:
-
-```
-pnpm changeset
-```
-
-Please send a descriptive changeset for each PR.
-
-## Publishing (maintainers only)
-
-To publish a new version of the library, first create a new version:
-
-```shell
-pnpm new-version
-```
-
-If everything looks good, commit the generated files and release the new version:
-
-```shell
-pnpm release
-git push # push to the main branch
-git push --tags
-```

 ## What you'll get
 
-- A set of pre-configured use cases to get you started, e.g. Agentic RAG, Data Analysis, Report Generation, etc.
-- A front-end using components from [shadcn/ui](https://ui.shadcn.com/). The app is set up as a chat interface that can answer questions about your data or interact with your agent
-- Your choice of two frameworks:
-  - **Next.js**: if you select this option, you’ll have a full-stack Next.js application that you can deploy to a host like [Vercel](https://vercel.com/) in just a few clicks. This uses [LlamaIndex.TS](https://www.npmjs.com/package/llamaindex), our TypeScript library with [LlamaIndex Server for TS](https://npmjs.com/package/@llamaindex/server).
-  - **Python FastAPI**: if you select this option, you’ll get full-stack Python application powered by the [llama-index Python package](https://pypi.org/project/llama-index/) and [LlamaIndex Server for Python](https://pypi.org/project/llama-index-server/)
+- A Next.js-powered front-end. The app is set up as a chat interface that can answer questions about your data (see below)
+  - You can style it with HTML and CSS, or you can optionally use components from [shadcn/ui](https://ui.shadcn.com/)
+- Your choice of 3 back-ends:
+  - **Next.js**: if you select this option, you’ll have a full stack Next.js application that you can deploy to a host like [Vercel](https://vercel.com/) in just a few clicks. This uses [LlamaIndex.TS](https://www.npmjs.com/package/llamaindex), our TypeScript library.
+  - **Express**: if you want a more traditional Node.js application you can generate an Express backend. This also uses LlamaIndex.TS.
+  - **Python FastAPI**: if you select this option you’ll get a backend powered by the [llama-index python package](https://pypi.org/project/llama-index/), which you can deploy to a service like Render or fly.io.
+- The back-end has a single endpoint that allows you to send the state of your chat and receive additional responses
+- You can choose whether you want a streaming or non-streaming back-end (if you're not sure, we recommend streaming)
+- You can choose whether you want to use `ContextChatEngine` or `SimpleChatEngine`
+  - `SimpleChatEngine` will just talk to the LLM directly without using your data
+  - `ContextChatEngine` will use your data to answer questions (see below).
 - The app uses OpenAI by default, so you'll need an OpenAI API key, or you can customize it to use any of the dozens of LLMs we support.
 
-Here's how it looks like:
-
-https://github.com/user-attachments/assets/d57af1a1-d99b-4e9c-98d9-4cbd1327eff8
-
 ## Using your data
 
-Optionally, you can supply your own data; the app will index it and make use of it, e.g. to answer questions. Your generated app will have a folder called `data`.
+If you've enabled `ContextChatEngine`, you can supply your own data and the app will index it and answer questions. Your generated app will have a folder called `data`:
 
-The app will ingest any supported files you put in this directory. Your Next.js apps use LlamaIndex.TS, so they will be able to ingest any PDF, text, CSV, Markdown, Word and HTML files. The Python backend can read even more types, including video and audio files.
+- With the Next.js backend this is `./data`
+- With the Express or Python backend this is in `./backend/data`
 
-Before you can use your data, you need to index it. If you're using the Next.js apps, run:

+
+Before you can use your data, you need to index it. If you're using the Next.js or Express apps, run:
 
 ```bash
 npm run generate
 ```
 
-Then re-start your app. Remember you'll need to re-run `generate` if you add new files to your `data` folder.
+Then re-start your app. Remember you'll need to re-run `generate` if you add new files to your `data` folder. If you're using the Python backend, you can trigger indexing of your data by deleting the `./storage` folder and re-starting the app.
 
-If you're using the Python backend, you can trigger indexing of your data by calling:
+## Don't want a front-end?
 
-```bash
-uv run generate
-```
+It's optional! If you've selected the Python or Express back-ends, just delete the `frontend` folder and you'll get an API without any front-end code.
 
-## Customizing the AI models
+## Customizing the LLM
 
-The app will default to OpenAI's `gpt-4.1` LLM and `text-embedding-3-large` embedding model.
+By default the app will use OpenAI's gpt-3.5-turbo model. If you want to use GPT-4, you can modify this by editing a file:
 
-If you want to use different models, add the `--ask-models` CLI parameter.
+- In the Next.js backend, edit `./app/api/chat/route.ts` and replace `gpt-3.5-turbo` with `gpt-4`
+- In the Express backend, edit `./backend/src/controllers/chat.controller.ts` and likewise replace `gpt-3.5-turbo` with `gpt-4`
+- In the Python backend, edit `./backend/app/utils/index.py` and once again replace `gpt-3.5-turbo` with `gpt-4`
 
-You can also replace one of the default models with one of our [dozens of other supported LLMs](https://docs.llamaindex.ai/en/stable/module_guides/models/llms/modules.html).
-
-To do so, you have to manually change the generated code (edit the `settings.ts` file for Typescript projects or the `settings.py` file for Python projects)

-# create-llama Package
-
-## Overview
-
-The `create-llama` package is a CLI tool for creating LlamaIndex-powered applications with one command. It's designed as a project generator that scaffolds various types of RAG (Retrieval-Augmented Generation) applications using different frameworks, databases, and AI model providers.
-
-## Package Structure
-
-### Core Files
-
-- **`index.ts`**: Main CLI entry point using Commander.js for argument parsing
-- **`create-app.ts`**: Core application creation logic and orchestration
-- **`package.json`**: Package configuration with binary entry point at `./dist/index.js`
-
-### Key Directories
-
-- **`helpers/`**: Utility functions for package management, file operations, and configuration
-- **`questions/`**: Interactive prompts for user configuration
-- **`templates/`**: Project templates for different frameworks and use cases
-- **`e2e/`**: End-to-end tests using Playwright
-
-## Core Functionality
-
-### CLI Interface
-
-The tool accepts numerous command-line options including:
-
-- Framework selection (`--framework`: nextjs, express, fastapi)
-- Template type (`--template`: streaming, multiagent, reflex, llamaindexserver)
-- Model providers (OpenAI, Anthropic, Groq, Ollama, etc.)
-- Vector databases (none, mongo, pg, pinecone, milvus, etc.)
-- Data sources (files, web URLs, databases)
-- Tools and observability options
-
-### Application Generation Flow
-
-1. **Project validation**: Checks project name validity and directory permissions
-2. **Interactive questioning**: Prompts user for configuration if not provided via CLI
-3. **Template installation**: Copies and configures appropriate templates
-4. **Environment setup**: Creates `.env` files with API keys and configuration
-5. **Dependencies**: Installs packages using detected/specified package manager
-6. **Post-install actions**: Can run the app, open VSCode, or install dependencies
-
-### Template System
-
-Templates are organized by:
-
-- **Framework**: NextJS (frontend), Express (Node backend), FastAPI (Python backend)
-- **Type**: Streaming chat, multiagent workflows, Reflex UI, LlamaIndex server
-- **Components**: Engines, loaders, providers, UI components, observability
-
-### Helper Functions
-
-Key helper modules include:
-
-- **Installation**: Package manager detection and dependency installation
-- **Data sources**: File copying, web scraping, database connection setup
-- **Providers**: Model provider configuration (OpenAI, Anthropic, etc.)
-- **Tools**: Integration with external tools (Wikipedia, weather, code generation)
-- **Environment**: `.env` file generation with API keys and settings
-
-## Development Commands
-
-### Build & Development
-
-- `npm run build`: Build the CLI using bash script
-- `npm run dev`: Watch mode development build
-- `npm run clean`: Clean build artifacts and temporary files
-
-### Testing
-
-- `npm run e2e`: Run all end-to-end tests
-- `npm run e2e:python`: Test Python-specific templates
-- `npm run e2e:typescript`: Test TypeScript-specific templates
-
-### Package Management
-
-- `npm run pack-install`: Create and install local package for testing
-
-## Architecture Notes
-
-### Model Configuration
-
-The tool supports multiple AI providers with a unified `ModelConfig` interface that includes:
-
-- Provider selection and API key management
-- Model and embedding model specification
-- Dimension configuration for embeddings
-
-### Data Source Handling
-
-Flexible data source configuration supporting:
-
-- Local files and directories
-- Web URLs with configurable crawling depth
-- Database connections with custom queries
-- Automatic file downloading and copying
-
-### Template Flexibility
-
-Templates use a component-based system allowing mix-and-match of:
-
-- Different frameworks (NextJS, Express, FastAPI)
-- Various vector databases
-- Multiple observability tools
-- Configurable tools and integrations
-
-This package serves as the foundation for rapidly prototyping and deploying LlamaIndex applications across different technology stacks and use cases.

-## Overview
-
-This example is using three agents to generate a blog post:
-
-- a researcher that retrieves content via a RAG pipeline,
-- a writer that specializes in writing blog posts and
-- a reviewer that is reviewing the blog post.
-
-There are three different methods how the agents can interact to reach their goal:
-
-1. [Choreography](./app/agents/choreography.py) - the agents decide themselves to delegate a task to another agent
-1. [Orchestrator](./app/agents/orchestrator.py) - a central orchestrator decides which agent should execute a task
-1. [Explicit Workflow](./app/agents/workflow.py) - a pre-defined workflow specific for the task is used to execute the tasks
-
-## Getting Started
-
-First, setup the environment with poetry:
-
-> **_Note:_** This step is not needed if you are using the dev-container.
-
-```shell
-uv sync
-```
-
-Then check the parameters that have been pre-configured in the `.env` file in this directory. (E.g. you might need to configure an `OPENAI_API_KEY` if you're using OpenAI as model provider).
-Second, generate the embeddings of the documents in the `./data` directory:
-
-```shell
-uv run generate
-```
-
-Third, run the development server:
-
-```shell
-uv run dev
-```
-
-Per default, the example is using the explicit workflow. You can change the example by setting the `EXAMPLE_TYPE` environment variable to `choreography` or `orchestrator`.
-The example provides one streaming API endpoint `/api/chat`.
-You can test the endpoint with the following curl request:
-
-```
-curl --location 'localhost:8000/api/chat' \
---header 'Content-Type: application/json' \
---data '{ "messages": [{ "role": "user", "content": "Write a blog post about physical standards for letters" }] }'
-```
-
-You can start editing the API by modifying `app/api/routers/chat.py` or `app/examples/workflow.py`. The API auto-updates as you save the files.
-
-Open [http://localhost:8000](http://localhost:8000) with your browser to start the app.
-
-To start the app optimized for **production**, run:
-
-```
-uv run prod
-```
-
-## Deployments
-
-For production deployments, check the [DEPLOY.md](DEPLOY.md) file.

-            If the conversation already includes the information and there is no new request for additional information from the user, you should return the appropriate content to the writer.
-            Otherwise, you must use tools to retrieve information or images needed for the task.
-
-            It's normal for the task to include some ambiguity. You must always think carefully about the context of the user's request to understand what are the main content needs to be retrieved.
-            Example:
-                Request: "Create a blog post about the history of the internet, write in English and publish in PDF format."
-                ->Though: The main content is "history of the internet", while "write in English and publish in PDF format" is a requirement for other agents.
-                Your task: Look for information in English about the history of the Internet.
-                This is not your task: Create a blog post or look for how to create a PDF.
-
-                Next request: "Publish the blog post in HTML format."
-                ->Though: User just asking for a format change, the previous content is still valid.
-                Your task: Return the previous content of the post to the writer. No need to do any research.
-                This is not your task: Look for how to create an HTML file.
-
-            If you use the tools but don't find any related information, please return "I didn't find any new information for {the topic}." along with the content you found. Don't try to make up information yourself.
-            If the request doesn't need any new information because it was in the conversation history, please return "The task doesn't need any new information. Please reuse the existing content in the conversation history."

-This is a [LlamaIndex](https://www.llamaindex.ai/) multi-agents project using [Workflows](https://docs.llamaindex.ai/en/stable/understanding/workflows/).
-
-## Getting Started
-
-First, setup the environment with poetry:
-
-> **_Note:_** This step is not needed if you are using the dev-container.
-
-```shell
-uv sync
-```
-
-Then check the parameters that have been pre-configured in the `.env` file in this directory. (E.g. you might need to configure an `OPENAI_API_KEY` if you're using OpenAI as model provider).
-Second, generate the embeddings of the documents in the `./data` directory:
-
-```shell
-uv run generate
-```
-
-Third, run the development server:
-
-```shell
-uv run dev
-```
-
-## Use Case: Deep Research over own documents
-
-The workflow performs deep research by retrieving and analyzing documents from the [data](./data) directory from multiple perspectives. The project includes a sample PDF about AI investment in 2024 to help you get started. You can also add your own documents by placing them in the data directory and running the generate script again to index them.
-
-After starting the server, go to [http://localhost:8000](http://localhost:8000) and send a message to the agent to write a blog post.
-E.g: "AI investment in 2024"
-
-To update the workflow, you can edit the [deep_research.py](./app/workflows/deep_research.py) file.
-
-By default, the workflow retrieves 10 results from your documents. To customize the amount of information covered in the answer, you can adjust the `TOP_K` environment variable in the `.env` file. A higher value will retrieve more results from your documents, potentially providing more comprehensive answers.
-
-## Deployments
