🧩 Overview

The Symfony Multi-Tenancy Bundle enables scalable, production-ready multi-tenancy for Symfony applications.

Ideal for SaaS platforms, region-based services, and multi-vendor e-commerce systems, this bundle is built around a database-per-tenant architecture, giving each tenant:

A fully isolated database
Independent schema and migrations
Configurable connection parameters (host, driver, credentials)

It integrates seamlessly with Doctrine and Symfony's service container, offering:

Automatic tenant database switching at runtime via SwitchDbEvent
Automatic tenant resolution from HTTP requests (subdomain, path, header, or custom)
Separate migration and fixture paths for main vs. tenant databases
Dedicated TenantEntityManager service for runtime isolation

For full usage examples and advanced configuration, see the documentation.

🔄 Automatic Tenant Resolution (v3.0.0+)

Automatically resolve the current tenant from incoming HTTP requests — no manual event dispatching required.

Supported Strategies

Strategy	Example	Description
`subdomain`	`tenant1.example.com`	Extracts tenant from subdomain
`path`	`/tenant1/dashboard`	Extracts tenant from URL path segment
`header`	`X-Tenant-ID: tenant1`	Extracts tenant from HTTP header
`host`	`client.com → tenant1`	Maps full hostname to tenant
`chain`	Multiple strategies	Tries resolvers in order with fallback

Quick Configuration

# config/packages/hakam_multi_tenancy.yaml
hakam_multi_tenancy:
    resolver:
        enabled: true
        strategy: subdomain  # subdomain | path | header | host | chain
        options:
            base_domain: 'example.com'  # for subdomain strategy

Strategy Examples

Subdomain-based (e.g., acme.myapp.com):

resolver:
    enabled: true
    strategy: subdomain
    options:
        base_domain: 'myapp.com'

Header-based (for APIs):

resolver:
    enabled: true
    strategy: header
    options:
        header_name: 'X-Tenant-ID'

Path-based (e.g., /acme/dashboard):

resolver:
    enabled: true
    strategy: path
    excluded_paths: ['/api/public', '/health']

Chain strategy (fallback support):

resolver:
    enabled: true
    strategy: chain
    options:
        chain_order: [header, subdomain, path]

Accessing Resolved Tenant

The resolved tenant ID is available in request attributes:

// In a controller
$tenantId = $request->attributes->get('_tenant');

Custom Resolver

Implement TenantResolverInterface for custom logic:

use Hakam\MultiTenancyBundle\Port\TenantResolverInterface;

class CustomResolver implements TenantResolverInterface
{
    public function resolve(Request $request): ?string
    {
        // Your custom logic
        return $request->cookies->get('tenant_id');
    }

    public function supports(Request $request): bool
    {
        return $request->cookies->has('tenant_id');
    }
}

Note: Automatic resolution is disabled by default for backward compatibility. Manual SwitchDbEvent dispatching continues to work.

🚀 Quick Installation

1. Via Symfony Flex (Recommended)

composer require hakam/multi-tenancy-bundle

Symfony Flex will automatically scaffold config, register the bundle, and create:

src/Entity/Main/
src/Entity/Tenant/
migrations/Main/
migrations/Tenant/

2. Manual Installation

composer require hakam/multi-tenancy-bundle

Then register in config/bundles.php, copy the example hakam_multi_tenancy.yaml from docs, and create the required directories.
