🚀 Getting Started

Choose your preferred setup method:

Option 1: 🐳 Docker (Recommended)

The fastest way to get Dyan running with production-ready containers.

Prerequisites

• Docker and Docker Compose installed

1. Clone the repo

git clone https://github.com/dyan-dev/dyan.git
cd dyan

2. Set up environment variables

Create a .env file in the project root:

# .env
JWT_SECRET=your_super_secret_jwt_key
VITE_API_URL=http://backend:3000

3. Build and run

docker compose up --build

That's it! 🚀 Visit http://localhost:5173 to start building your APIs.

• Frontend: http://localhost:5173
• Backend: http://localhost:3000
• Data: Persisted in Docker volume (survives restarts)

Managing Docker setup

# Stop services
docker compose down

# Remove all data (including database)
docker compose down -v

Option 2: 🛠️ Local Development

For contributors or those who want to modify the source code.

1. Clone the repo

git clone https://github.com/dyan-dev/dyan.git
cd dyan

2. Install dependencies

Make sure you have pnpm installed.

pnpm install

3. Set up your environment

cp .env.example .env

To skip email sending in development:

EMAIL_MOCK=true

Note: The magic link will be printed on console of backend.

4. Run backend and frontend

In the root folder, run:

# Start the frontend (localhost:5173)
pnpm --filter frontend dev

# Start the backend (localhost:3000)
pnpm --filter backend exec prisma generate
pnpm --filter backend exec prisma migrate deploy
pnpm --filter backend dev

Visit http://localhost:5173 to start building your APIs.
