Frequently Asked Questions
PHP
What makes PHP ideal for SaaS development?
PHP excels in SaaS development due to its robust ecosystem, strong typing capabilities, and excellent library support. PHP boilerplates leverage language-specific features to provide type-safe database queries, efficient API routing, and optimized runtime performance. The language's maturity means you get battle-tested packages for authentication, payment processing, and background jobs that integrate seamlessly.
Laravel
What Laravel-specific architecture patterns are implemented?
Laravel boilerplates leverage the framework's native architecture patterns including its routing system, middleware pipeline, and controller/handler structure. They implement Laravel's conventions for separating concerns, dependency injection, and service layer patterns. The codebase follows Laravel's best practices for organizing models, views/components, and business logic to ensure maintainability as your application grows.
Tailwind CSS
What Tailwind CSS-specific component architecture is used?
Tailwind CSS boilerplates follow the framework's component composition patterns with reusable, atomic design components. They implement Tailwind CSS's best practices for component structure, props handling, event management, and lifecycle methods. The component library includes authentication flows, dashboards, data tables, forms with validation, and navigation—all built with Tailwind CSS's native features like hooks (React), composition API (Vue), or directives (Angular).
Turbine UI
What Turbine UI-specific component architecture is used?
Turbine UI boilerplates follow the framework's component composition patterns with reusable, atomic design components. They implement Turbine UI's best practices for component structure, props handling, event management, and lifecycle methods. The component library includes authentication flows, dashboards, data tables, forms with validation, and navigation—all built with Turbine UI's native features like hooks (React), composition API (Vue), or directives (Angular).
MySQL
What MySQL-specific features are leveraged in these boilerplates?
MySQL boilerplates utilize the database's native capabilities including its transaction model (ACID for SQL, eventual consistency for NoSQL), indexing strategies (B-tree, GiST, full-text search), and advanced features like JSON columns, array types, window functions, or document queries. The schema design takes advantage of MySQL's strengths—whether that's PostgreSQL's JSONB, MySQL's full-text search, MongoDB's aggregation pipeline, or Redis's data structures.
Lemon Squeezy
What Lemon Squeezy API features are implemented?
Lemon Squeezy boilerplates implement the provider's complete API suite including checkout sessions, subscription lifecycle management, customer portal, webhook event handling, and invoice generation. They use Lemon Squeezy's latest API version with proper error handling, idempotency keys, and retry logic. The integration includes Lemon Squeezy-specific features like payment intents, setup intents, subscription schedules, and tax calculation APIs.
PHP
What PHP-specific tools and libraries are included?
PHP boilerplates include the language's most popular and production-proven tools. This typically includes testing frameworks, linters, formatters, build tools, and package managers specific to PHP. You'll get pre-configured toolchains that enforce best practices, automated testing pipelines, and development environments optimized for PHP development workflows.
Laravel
How does Laravel's ORM/database layer work in these boilerplates?
Laravel boilerplates use the framework's native ORM or query builder (Prisma, Eloquent, Active Record, SQLAlchemy, etc.) with pre-configured models for users, subscriptions, teams, and common SaaS entities. They include optimized queries, relationships, migrations, seeders, and database connection pooling. The implementation leverages Laravel's specific features like eager loading, query scopes, and transaction handling for performance.
Tailwind CSS
How is state management handled in Tailwind CSS boilerplates?
Tailwind CSS boilerplates use the framework's recommended state management approach—whether that's React Context + hooks, Redux Toolkit, Zustand, Pinia (Vue), NgRx (Angular), or Svelte stores. They include pre-configured state slices for authentication, user data, subscriptions, and UI state with proper TypeScript typing. The implementation follows Tailwind CSS's patterns for global state, local component state, and server state synchronization.
Turbine UI
How is state management handled in Turbine UI boilerplates?
Turbine UI boilerplates use the framework's recommended state management approach—whether that's React Context + hooks, Redux Toolkit, Zustand, Pinia (Vue), NgRx (Angular), or Svelte stores. They include pre-configured state slices for authentication, user data, subscriptions, and UI state with proper TypeScript typing. The implementation follows Turbine UI's patterns for global state, local component state, and server state synchronization.
MySQL
How is the MySQL schema designed for SaaS applications?
MySQL boilerplates include production-tested schemas for multi-tenancy, user management, subscriptions, and billing. The design follows MySQL's best practices for data modeling—whether that's normalized tables with foreign keys (SQL), embedded documents vs. references (MongoDB), or partition key strategies (DynamoDB). Schemas include proper constraints, default values, and relationship management optimized for MySQL's query engine.
Lemon Squeezy
How are Lemon Squeezy webhooks handled securely?
Lemon Squeezy webhooks are verified using the provider's signature validation to prevent spoofing attacks. The boilerplate includes webhook endpoints with proper Lemon Squeezy signature verification, event type filtering, and idempotent event processing to handle duplicate deliveries. Events are processed asynchronously with retry logic, and the implementation handles Lemon Squeezy's specific webhook events like subscription updates, payment failures, and customer changes.
