Frequently Asked Questions

Dart

What makes Dart ideal for SaaS development?

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

JavaScript

Firebase

What Firebase-specific architecture patterns are implemented?

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

Flutter

What Flutter-specific architecture patterns are implemented?

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

Node.js

What Node.js-specific architecture patterns are implemented?

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

Flutter

What Flutter-specific component architecture is used?

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

Firestore

What Firestore-specific features are leveraged in these boilerplates?

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

In-App Purchases

What In-App Purchases API features are implemented?

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

RevenueCat

What RevenueCat API features are implemented?

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

Dart

What Dart-specific tools and libraries are included?

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

JavaScript

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

Firebase

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

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