# Project Name

## Overview

This project is built using NestJS and LiveKit server SDK to manage video collaboration sessions, scheduling, and user services. It utilizes Prisma as an ORM for database interactions.

## Getting Started

### Prerequisites

- Node.js installed on your machine.
- A PostgreSQL database or another SQL database supported by Prisma.
- Environment variables for LiveKit and database credentials set up correctly.

### Installation

1. **Clone the repository:**

    ```bash
    git clone https://github.com/EPESS/epess-web-backend.git
    cd epess-server
    ```

2. **Install the dependencies:**

    ```bash
    npm install
    ```

3. **Create the `.env` file:**

    Create a file named `.env` at the root of the project and set the following environment variables:

    ```
    LIVEKIT_API_KEY=your_livekit_api_key
    LIVEKIT_API_SECRET=your_livekit_api_secret
    DATABASE_URL=your_database_url
    ```

4. **Run database migrations:**

    Ensure your database is set up, and use Prisma to run migrations.

    ```bash
    npx prisma migrate dev
    ```

### Running the Application

To start the application:

```bash
npm run start:dev
```

This command will start the application in development mode with live reload enabled.

## Services Description

### LiveKit Participant Service

This service handles operations related to participants in a LiveKit room. It utilizes the `RoomServiceClient` from the `livekit-server-sdk`.

Reference:

```typescript:src/LiveKit/livekit.participant.service.ts
startLine: 1
endLine: 8
```

### LiveKit Service

Responsible for generating access tokens for users to join LiveKit rooms. It utilizes API keys and secrets for authorization.

Reference:

```typescript:src/LiveKit/livekit.service.ts
startLine: 1
endLine: 26
```

### Other Services

The project includes additional service files for room management (`livekit.room.service.ts`) and integration with other modules like notifications and payment handling.

## Additional Notes

- Ensure that the Prisma service is properly configured and running.
- Always make sure to keep your environment variables secure.
- To seed the database with initial data, refer to `epess-database/prisma/seed.js`.
