## Overview

Gorm-multitenancy provides a Go framework for building multi-tenant applications, streamlining
tenant management and model migrations. It abstracts multitenancy complexities through a unified,
database-agnostic API compatible with GORM.

## Multitenancy Approaches

There are three common approaches to multitenancy in a database:

- Shared database, shared schema
- Shared database, separate schemas
- Separate databases

Depending on the database in use, this package utilizes either the _"shared database, separate schemas"_ or _"separate databases"_ strategy, ensuring a smooth integration with your existing database configuration through the provision of tailored drivers.

## Features

- **GORM Integration**: Simplifies [GORM](https://gorm.io/) usage in multi-tenant environments, offering a unified API alongside direct access to driver-specific APIs for flexibility.
- **Custom Database Drivers**: Enhances existing drivers for easy multitenancy setup without altering initialization.
- **HTTP Middleware**: Provides middleware for easy tenant context management in web applications.

## Supported Databases

| Database | Approach |
|----------|----------|
| PostgreSQL | Shared database, separate schemas |
| MySQL | Separate databases |

## Router Integration

- Echo - [Guide](https://pkg.go.dev/github.com/bartventer/gorm-multitenancy/middleware/echo/v8)
- Gin - [Guide](https://pkg.go.dev/github.com/bartventer/gorm-multitenancy/middleware/gin/v8)
- Iris - [Guide](https://pkg.go.dev/github.com/bartventer/gorm-multitenancy/middleware/iris/v8)
- Net/HTTP - [Guide](https://pkg.go.dev/github.com/bartventer/gorm-multitenancy/middleware/nethttp/v8)

## Installation

Install the core package:

```bash
go get -u github.com/bartventer/gorm-multitenancy/v8
```

Install the database-specific driver:

```bash
# PostgreSQL
go get -u github.com/bartventer/gorm-multitenancy/postgres/v8

# MySQL
go get -u github.com/bartventer/gorm-multitenancy/mysql/v8
```

Optionally, install the router-specific middleware:

```bash
# Echo
go get -u github.com/bartventer/gorm-multitenancy/middleware/echo/v8

# Gin
go get -u github.com/bartventer/gorm-multitenancy/middleware/gin/v8

# Iris
go get -u github.com/bartventer/gorm-multitenancy/middleware/iris/v8

# Net/HTTP
go get -u github.com/bartventer/gorm-multitenancy/middleware/nethttp/v8
```
