Laravel Multitenancy Laravel Package

title: Base installation weight: 1

This package can be installed via composer:

composer require spatie/laravel-multitenancy

Publishing the config file

You must publish the config file:

php artisan vendor:publish --provider="Spatie\Multitenancy\MultitenancyServiceProvider" --tag="multitenancy-config"

This is the default content of the config file that will be published at config/multitenancy.php:

Protecting against cross tenant abuse

To prevent users from a tenant abusing their session to access another tenant, you must use the Spatie\Multitenancy\Http\Middleware\EnsureValidTenantSession middleware on all tenant-aware routes.

If all your application routes are tenant-aware, you can add it to your global middleware in bootstrap/app.php

// in `bootstrap/app.php`

return Application::configure(basePath: dirname(__DIR__))
    // ...
    ->withMiddleware(function (Middleware $middleware) {
        $middleware
            ->web(append: [
                \Spatie\Multitenancy\Http\Middleware\NeedsTenant::class,
                \Spatie\Multitenancy\Http\Middleware\EnsureValidTenantSession::class,
            ]);
    });

If only some routes are tenant-aware, create a new middleware group:

// in `bootstrap/app.php`

return Application::configure(basePath: dirname(__DIR__))
    // ...
    ->withMiddleware(function (Middleware $middleware) {
        $middleware
            ->group('tenant', [
                \Spatie\Multitenancy\Http\Middleware\NeedsTenant::class,
                \Spatie\Multitenancy\Http\Middleware\EnsureValidTenantSession::class,
            ]);
    });

Then apply the group to the appropriate routes:

// in a routes file

Route::middleware('tenant')->group(function() {
    // routes
});

This middleware will respond with an unauthorized response code (401) when the user tries to use their session to view another tenant. Make sure to include \Spatie\Multitenancy\Http\Middleware\NeedsTenant first, as this will handle any cases where a valid tenant cannot be found.

Next steps

If you prefer to use just one glorious database for all your tenants, read the installation instructions for using a single database.

If you want to use separate databases for each tenant, head over to the installation instructions for using multiple databases.
