Multi-tenant RAG

Leverage Neon’s database-per-user and Inngest’s multi-tenancy to deploy fair and reliable RAG at scale.

Tech Stack

• Next.js - React framework
• Neon - Serverless Postgres database
• Inngest - Serverless Workflow engine

Prerequisites

Before you begin, ensure you have:

• Node.js and npm installed
• A Neon account
• An OpenAI account
• A SERP API API key

Getting Started

1. Clone the repository:

git clone <repository-url>

2. Install dependencies:

npm install

3. Set up environment variables: Create a .env.local file in the root directory:

# Neon Database
DATABASE_URL=
NEON_API_KEY=

# OpenAI
OPENAI_API_KEY=

# SERP API
SERP_API_KEY=

Here is how you can get the above values:

• Neon Database URL:

  • Go to your Neon project
  • Navigate to Connection Details
  • Copy the URL

• Neon API Key:

  • Go to your Neon Console
  • Navigate to your Profile page
  • Create a new API Key and copy it

• OpenAI:

  • Go to OpenAI
  • Navigate to View API keys
  • Copy the API Key

• SERP API:

  • Go to SERP API
  • Sign up and get your API key

4. Initialize the database schema:

Go over your Neon Console and navigate to the SQL Editor. Copy the contents of db/schema.sql and paste it into the SQL Editor. Running the query will create the schema.

Then start the Next.js development server (npm run dev) and navigate to http://localhost:3000/api/setup.

This will create the initial workspaces.

Development

1. Start the Next.js development server:

npm run dev

2. In a separate terminal, start the Inngest dev server:

npx inngest-cli@latest dev

3. Visit:
   • http://localhost:3000 - Application
   • http://localhost:8288 - Inngest dashboard
