DaisyUI

What DaisyUI-specific component architecture is used?

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

React

What React-specific component architecture is used?

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

Django ORM

What Django ORM-specific features are leveraged in these boilerplates?

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

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.

Python

Astro

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

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