Running Locally

This application requires Node.js v24+.

Cloning the repository to the local machine:

git clone https://github.com/nabarvn/documon.git
cd documon

Installing the dependencies:

pnpm install

Setting up the .env file:

cp .env.example .env

[!IMPORTANT] Ensure you populate the variables with your respective API keys and configuration values before proceeding.

Configuring Prisma:

pnpm prisma generate

Forwarding Stripe webhooks:

Install the Stripe CLI and log in:

stripe login

In a second terminal, forward events to the local app and leave that process running:

stripe listen --events checkout.session.completed,customer.subscription.updated,customer.subscription.deleted --forward-to localhost:3000/api/webhooks/stripe

The CLI prints a whsec_... secret. Put that value in STRIPE_WEBHOOK_SECRET in .env before starting the app.

Running the application:

pnpm dev
