Frequently Asked Questions

JavaScript

What makes JavaScript ideal for SaaS development?

JavaScript excels in SaaS development due to its robust ecosystem, strong typing capabilities, and excellent library support. JavaScript 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.

TypeScript

What makes TypeScript ideal for SaaS development?

TypeScript excels in SaaS development due to its robust ecosystem, strong typing capabilities, and excellent library support. TypeScript 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.

Next.js

What Next.js-specific architecture patterns are implemented?

Next.js boilerplates leverage the framework's native architecture patterns including its routing system, middleware pipeline, and controller/handler structure. They implement Next.js's conventions for separating concerns, dependency injection, and service layer patterns. The codebase follows Next.js's best practices for organizing models, views/components, and business logic to ensure maintainability as your application grows.

React

What React-specific architecture patterns are implemented?

React boilerplates leverage the framework's native architecture patterns including its routing system, middleware pipeline, and controller/handler structure. They implement React's conventions for separating concerns, dependency injection, and service layer patterns. The codebase follows React's best practices for organizing models, views/components, and business logic to ensure maintainability as your application grows.

shadcn/ui

What shadcn/ui-specific component architecture is used?

shadcn/ui boilerplates follow the framework's component composition patterns with reusable, atomic design components. They implement shadcn/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 shadcn/ui's native features like hooks (React), composition API (Vue), or directives (Angular).

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).

PostgreSQL

What PostgreSQL-specific features are leveraged in these boilerplates?

PostgreSQL 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 PostgreSQL's strengths—whether that's PostgreSQL's JSONB, MySQL's full-text search, MongoDB's aggregation pipeline, or Redis's data structures.

Supabase

What Supabase-specific features are leveraged in these boilerplates?

Supabase 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 Supabase'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.

Stripe

What Stripe API features are implemented?

Stripe boilerplates implement the provider's complete API suite including checkout sessions, subscription lifecycle management, customer portal, webhook event handling, and invoice generation. They use Stripe's latest API version with proper error handling, idempotency keys, and retry logic. The integration includes Stripe-specific features like payment intents, setup intents, subscription schedules, and tax calculation APIs.

JavaScript

What JavaScript-specific tools and libraries are included?

JavaScript 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 JavaScript. You'll get pre-configured toolchains that enforce best practices, automated testing pipelines, and development environments optimized for JavaScript development workflows.

TypeScript

What TypeScript-specific tools and libraries are included?

TypeScript 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 TypeScript. You'll get pre-configured toolchains that enforce best practices, automated testing pipelines, and development environments optimized for TypeScript development workflows.

Next.js

How does Next.js's ORM/database layer work in these boilerplates?

Next.js 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 Next.js's specific features like eager loading, query scopes, and transaction handling for performance.

React

How does React's ORM/database layer work in these boilerplates?

React 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 React's specific features like eager loading, query scopes, and transaction handling for performance.

shadcn/ui

How is state management handled in shadcn/ui boilerplates?

shadcn/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 shadcn/ui's patterns for global state, local component state, and server state synchronization.
