FinAI - React / Express / NodeLlamaCPP Financial App (get financial predictions based on a LLM)

A Web App built with React as a Frontend and Express as a Backend. It uses Node LlamaCPP as a way to run an LLM locally and get financial predictions based on data from different APIs. Data store: MongoDB.

Frontend: React (Vite + Typescript)

Backend-Local: Express + MongoDB + Node LLAMA CPP LLM

Backend-API: Express + Anthropic API / SDK

Getting Started (Local):

You need to setup the LLM you want to be using in the backend. The LLM should be saved as a .gguf file in the backend/models folder.

• Validate LLM:
  npx --no node-llama-cpp chat --model PATH-TO-MODEL-DIR npx --no node-llama-cpp chat --model c:/projects/finai/backend/models/codellama-13b.Q3_K_M.gguf
• Or do a test request:

curl --location 'localhost:9000/api/llm' \
--header 'Content-Type: application/json' \
--data '{ "messages": "Hello there" }'

• Or call the express API endpoint localhost:9000/api/llm to see the result

Some examples for models and formats: LLMTypeDefinitions.json

Then you can run the below commands from the FinAI (main) directory and start the project:

npm i
npm start

This installs and starts both the FE and BE using the npm tool 'concurrently'. Or you can run the commands separately in the frontend / backend folders to have them running in separate instances/terminals.

Getting Started (Anthropic API):

Create a .env.local file in the root directory:

ANTHROPIC_API_KEY=your_api_key_here

Run the development server:

npm i
npm start
