STRIPE_WEBHOOK_SECRET=whsec_... # Trigger.dev background jobs (required for production scheduled tasks/retries) TRIGGER_PROJECT_REF=proj_... TRIGGER_SECRET_KEY=tr_dev_... # S3 Storage (optional) S3_BUCKET=dubbl-uploads S3_REGION=us-east-1 S3_ACCESS_KEY_ID=... S3_SECRET_ACCESS_KEY=... S3_ENDPOINT=https://s3.amazonaws.com ``` ### Database Setup ```bash # Push schema to database pnpm db:push # Seed with demo data (optional) pnpm db:seed ``` ### Run ```bash pnpm dev ``` Open [http://localhost:3000](http://localhost:3000) in your browser. If you ran the seed script, log in with `demo@dubbl.dev` / `password123`. ### Background Jobs Dubbl uses Trigger.dev for scheduled maintenance and delayed retries. For production, set `TRIGGER_PROJECT_REF` and `TRIGGER_SECRET_KEY`, then deploy the tasks: ```bash pnpm trigger:deploy ``` Without Trigger.dev, scheduled backups, bookkeeping maintenance, invoicing maintenance, trash purge, report schedules, notification digests, Stripe retries, and webhook delivery retries will not run automatically. Webhook retries are scheduled when a delivery fails, so keep `TRIGGER_SECRET_KEY` configured in the app runtime before accepting webhook traffic. ## Tech Stack - **Framework** - [Next.js](https://nextjs.org) (App Router) - **Database** - [PostgreSQL](https://www.postgresql.org) with [Drizzle ORM](https://orm.drizzle.team) - **Auth** - [NextAuth.js](https://next-auth.js.org) - **UI** - [Tailwind CSS](https://tailwindcss.com) + [shadcn/ui](https://ui.shadcn.com) - **Docs** - [Fumadocs](https://fumadocs.vercel.app) ## Self-Hosting See the [Self-Hosting Guide](https://dubbl.dev/docs/self-hosting) for instructions on deploying dubbl with Docker. ## MCP Server dubbl includes a built-in [Model Context Protocol](https://modelcontextprotocol.io) server that lets any MCP-compatible AI agent interact with your accounting data.
