This project is a monorepo setup using Yarn workspaces. It includes:
- A React.js frontend
- A Python backend for AI and dataset pipeline
- A JavaScript backend using Express.js or Next.js
- Integration with Langchain for AI chat and RAG features to analyze and chat with PDF files
Ensure you have the following installed:
- Node.js and npm
- Yarn
- Python
-
Initialize the Monorepo
Create a new directory and initialize it with a
package.json
file:mkdir ai-project cd ai-project npm init -y
-
Set Up Yarn Workspaces
Add the following configuration to your package.json
file:
{
"private": true,
"workspaces": [
"packages/*"
],
"scripts": {
"start:frontend": "yarn workspace frontend start",
"start:backend-python": "yarn workspace backend-python start",
"start:backend-js": "yarn workspace backend-js start",
"start": "concurrently \"yarn start:frontend\" \"yarn start:backend-python\" \"yarn start:backend-js\""
}
}
- Add Packages
Create directories for each part of your project:
mkdir -p packages/frontend
mkdir -p packages/backend-python
mkdir -p packages/backend-js
- Set Up the Frontend
Navigate to the frontend package and set up a React.js project:
cd packages/frontend
npx create-react-app .
- Set Up the Backend (Python)
Navigate to the backend-python package and set up a Python project:
cd ../backend-python
python -m venv venv
source venv/bin/activate
pip install fastapi uvicorn langchain
# or: pip install -r requirements.txt
- Set Up the Backend (JavaScript)
Navigate to the backend-js package and set up an Express.js or Next.js project:
cd ../backend-js
npm init -y
npm install express
- Set up Next-js
$ cd packages
$ npx create-next-app@latest next-js
- Configure Yarn Workspaces
Ensure all dependencies are linked correctly. Add the following to your root package.json
:
{
"private": true,
"workspaces": [
"packages/*"
]
}
- Install Dependencies
Run Yarn to install all dependencies and link the packages:
yarn install
- Run the Project
Use the scripts defined in the root package.json to start your project:
yarn start
This setup should give you a working monorepo project with a React.js frontend, Python backend for AI and data processing, and a JavaScript backend using Express.js or Next.js. Integrate Langchain for AI chat and RAG features for PDF analysis as needed.
By following these steps and configurations, you’ll have a robust and maintainable monorepo setup that integrates JavaScript and Python projects efficiently. This approach ensures a consistent development environment and simplifies the management of multiple services within a single repository.
