File Structure ----------------- [](#1-file-structure) ``` composer.json config/saas-kit.php database/migrations/2024_01_01_000001_create_saas_kit_tenants_table.php database/migrations/2024_01_01_000002_create_saas_kit_users_tables.php database/migrations/2024_01_01_000003_create_saas_kit_rbac_tables.php database/migrations/2024_01_01_000004_create_saas_kit_billing_tables.php database/migrations/2024_01_01_000005_create_saas_kit_feature_tables.php database/migrations/2024_01_01_000006_create_saas_kit_invoices_table.php database/migrations/2024_01_01_000007_create_saas_kit_webhook_events_table.php database/migrations/2024_01_01_000008_create_saas_kit_audit_logs_table.php routes/api.php src/ Api/ Admin/ Audit/ Billing/ Features/ Invoices/ Mcp/ Payments/ Rbac/ Seo/ Tenancy/ Users/ Webhooks/ tests/Unit/ ``` 2. Code Per Module ------------------ [](#2-code-per-module) Each module follows the same DDD-lite shape: - `Contracts`: public interfaces for extension points. - `DTOs`: immutable input/output objects. - `Models`: package-owned Eloquent persistence models. - `Repositories`: Eloquent implementations behind contracts. - `Services`: business use cases; controllers are intentionally omitted. - `Events` and `Listeners`: lifecycle hooks and audit integration. - `Providers`: module-local service container bindings. Implemented modules: - `Tenancy`: tenant repository, header resolver, tenant context, pluggable isolation strategies, tenant resolution middleware. - `Users`: SaaS user model, profile model, CRUD service, authentication hook dispatcher. - `Rbac`: native roles and permissions with guard names, model-role assignments, permission middleware. - `Billing`: plans, trials, coupons, discounts, subscriptions, usage records, plan enforcement middleware. - `Payments`: gateway interface, gateway registry, payment service, Stripe adapter. - `Invoices`: invoice generation, invoice repository, PDF renderer interface, built-in simple PDF renderer. - `Webhooks`: raw webhook persistence, provider event normalization, payment/subscription webhook events. - `Features`: feature flags per plan, limits, feature gate service, feature middleware. - `Admin`: backend dashboard snapshot service. - `Audit`: auditable lifecycle events, audit log service, wildcard listener. - `Api`: JSON resource serializer and optional GraphQL schema extension hook. - `Mcp`: Streamable HTTP-compatible JSON-RPC endpoint with read-only SaaS Kit tools. - `Seo`: canonical URLs, meta tags, Open Graph, Twitter card, and JSON-LD metadata generation. 3. Service Provider Bindings ---------------------------- [](#3-service-provider-bindings) Laravel auto-discovers `Caydeesoft\SaasKit\SaasKitServiceProvider`, which registers module providers for tenancy, users, RBAC, billing, payments, invoices, webhooks, feature flags, admin services, audit logs, API hooks, MCP tools, and SEO metadata. Publish config and migrations: ``` php artisan vendor:publish --tag=saas-kit-config php artisan vendor:publish --tag=saas-kit-migrations php artisan migrate ``` Middleware aliases: ``` Route::middleware(['saas.tenant', 'saas.subscription', 'saas.feature:exports'])->group(function () { // Application routes. }); ``` API endpoints: ``` GET /api/saas-kit/health POST /api/saas-kit/mcp GET /api/saas-kit/mcp ``` The MCP endpoint follows the 2025-11-25 JSON-RPC message shape for initialization, `tools/list`, and `tools/call`. The GET method returns `405 Method Not Allowed` when server-sent event streaming is not enabled. 4. Example Usage ---------------- [](#4-example-usage) ``` use Caydeesoft\SaasKit\Billing\Contracts\BillingServiceInterface; use Caydeesoft\SaasKit\Billing\DTOs\PlanData; $billing = app(BillingServiceInterface::class); $plan = $billing->createPlan(new PlanData( name: 'Growth', key: 'growth', interval: 'monthly', amount: 4900, currency: 'usd', features: ['projects' => 25, 'seats' => 10], )); ``` ``` use Caydeesoft\SaasKit\Payments\Contracts\PaymentServiceInterface; use Caydeesoft\SaasKit\Payments\DTOs\CheckoutSessionData; $payments = app(PaymentServiceInterface::class); $session = $payments->createCheckoutSession(new CheckoutSessionData( customerEmail: 'founder@example.com', successUrl: 'https://app.example.com/billing/success', cancelUrl: 'https://app.example.com/billing/cancel', lineItems: [['price' => 'price_123', 'quantity' => 1]], )); ``` ``` use Caydeesoft\SaasKit\Features\Contracts\FeatureGateInterface; use Caydeesoft\SaasKit\Features\DTOs\FeatureData; $features = app(FeatureGateInterface::class); $features->createFeature(new FeatureData('Exports', 'exports')); $features->enableForPlan($plan->id, 'exports', limit: 100); ``` ``` use Caydeesoft\SaasKit\Invoices\Contracts\InvoiceServiceInterface; use Caydeesoft\SaasKit\Invoices\DTOs\InvoiceLineData; $invoice = app(InvoiceServiceInterface::class)->generateForSubscription($subscription, [ new InvoiceLineData('Growth plan', 1, 4900), ]); $pdfBytes = app(InvoiceServiceInterface::class)->exportPdf($invoice); ``` 5. MCP Usage ------------ [](#5-mcp-usage) ``` { "jsonrpc": "2.0", "id": 1, "method": "initialize", "params": { "protocolVersion": "2025-11-25", "capabilities": {}, "clientInfo": { "name": "example-client", "version": "1.0.0" } } } ``` Available tools: - `saas_kit.health`: returns package health status. - `saas_kit.seo.metadata`: generates canonical, meta, Open Graph, Twitter, and JSON-LD metadata for a SaaS page. ``` { "jsonrpc": "2.0", "id": 2, "method": "tools/call", "params": { "name": "saas_kit.seo.metadata", "arguments": { "title": "Billing Automation for SaaS Teams", "description": "Launch subscription billing, invoices, and feature gates faster in Laravel.", "url": "https://example.com/billing", "siteName": "Example SaaS", "keywords": ["laravel saas", "subscription billing"] } } } ``` 6. SEO Usage ------------ [](#6-seo-usage) ``` use Caydeesoft\SaasKit\Seo\Contracts\SeoMetadataGeneratorInterface; use Caydeesoft\SaasKit\Seo\DTOs\SeoMetadataData; $metadata = app(SeoMetadataGeneratorInterface::class)->generate(new SeoMetadataData( title: 'Subscription Billing for Laravel SaaS', description: 'Create plans, trials, invoices, payment workflows, and feature limits with SaaS Kit.', url: 'https://example.com/billing', siteName: 'Example SaaS', keywords: ['laravel saas', 'billing', 'subscriptions'], )); // Use the returned canonical, meta, open_graph, twitter, and json_ld arrays in your Blade or frontend head renderer. ``` ### Health Score 40 — FairBetter than 86% of packages Maintenance95 Actively maintained with recent releases Popularity5 Limited adoption so far Community6 Small or concentrated contributor base Maturity46 Maturing project, gaining track record Bus Factor1 Top contributor holds 100% of commits — single point of failure How is this calculated?**Maintenance (25%)** — Last commit recency, latest release date, and issue-to-star ratio.
