Core Frontend Adapters

The Core Frontend Adapters project serves as the parent framework for implementing modular, reusable adapters that connect front-end applications to various data sources and service layers. Built to provide a high-level abstraction for integration tasks, this project is designed to simplify and standardize communication between front-end components and diverse backend systems, APIs, and third-party services.

The Core Frontend Adapters framework adheres to Clean Architecture principles, ensuring that integration logic remains modular, testable, and easily adaptable to evolving requirements across different business domains.

Purpose of Core Frontend Adapters

The Core Frontend Adapters framework is the foundation for creating specific adapters tailored to diverse use cases, such as REST APIs, GraphQL endpoints, database integrations, and other data sources. Its main objectives are:

  1. Standardization: Provide a unified structure for building front-end integration logic, promoting consistency across projects.
  2. Reusability: Allow developers to reuse the fundamental adapter logic across multiple applications and modules.
  3. Flexibility: Enable customization and extension of adapters for specific workflows and domain requirements.
  4. Separation of Concerns: Ensure that front-end integration tasks remain decoupled from business logic and UI components, adhering to Clean Architecture principles.

By serving as the parent project for front-end adapter implementations, Core Frontend Adapters acts as the base library upon which domain-specific adapters, such as REST adapters, GraphQL adapters, or custom data connectors, can be built and extended.

Key Features

  1. High-Level Abstraction: Provides a common structure for handling communication logic across different data sources (e.g., REST, GraphQL, databases).
  2. Base Implementation Modules: Includes foundational tools and utilities such as HTTP request wrappers, error handling mechanisms, and data transformation utilities.
  3. Modular Architecture: Focuses on interface-driven design, enabling adapters to remain independent and reusable across diverse projects.
  4. Extensibility: Supports the creation of specialized adapters for unique workflows, business processes, and data requirements.
  5. Clean Architecture Compliance: Maintains strict separation of concerns, isolating integration logic from the UI layer.

How Core Frontend Adapters Work

High-Level Workflow

  1. Define Base Interfaces:

The framework provides base interfaces that standardize how adapters interact with front-end components and data sources. These interfaces serve as contracts that are implemented by specific adapter modules.

  1. Build Specialized Adapters:

Developers use the Core Frontend Adapters framework to create reusable adapters for specific data sources. For example, an adapter for REST APIs might handle HTTP requests and responses, while an adapter for GraphQL might encapsulate queries and mutations.

  1. Integrate with Front-End:

The adapters are integrated into front-end applications to provide a unified way to fetch, send, and manipulate data. This ensures consistency across all interactions while keeping the UI components decoupled from low-level data logic.

  1. Extend and Customize:

Applications or modules can extend the base adapters provided by Core Frontend Adapters to address domain-specific needs or add features like caching, authentication, or conditional data transformations.

Supported Use Cases

REST API Adapters

Core Frontend Adapters provides tools to build modules like @machb/front-rest-adapters, which abstract HTTP communication logic for RESTful services.

GraphQL Adapters

Build GraphQL adapters to manage queries, mutations, and subscription workflows seamlessly.

Database Adapters

Integrate front-end applications with data storage layers like IndexedDB or remote database systems for direct querying and manipulation.

Custom Adapters

Create adapters for specific workflows, such as integration with third-party services, analytics APIs, or IoT devices. Example: An adapter for payment gateways or user identity providers.

Abstraction and Modularity

Core Frontend Adapters encapsulates communication logic for diverse data sources into modular bricks that adhere to Clean Architecture principles.

Key Architectural Highlights

  1. Encapsulation

    • Adapters abstract the details of data communication, ensuring front-end components only interact with standardized interfaces.
    • This encapsulation promotes reuse and simplifies testing.

  2. Independence

    • Adapters remain independent of specific implementation details, such as endpoint URLs or authentication mechanisms.
    • Developers can swap adapters without impacting other parts of the application.

  3. Extensibility

    • Developers can extend Core Frontend Adapters to build custom logic tailored to business-specific requirements.
    • Example: Extending error handling logic or adding specialized caching mechanisms.

Benefits of Core Frontend Adapters

  1. Standardization: Maintain consistent interaction patterns across diverse data sources.
  2. Reusability: Build once and reuse adapters across multiple projects.
  3. Maintainability: Decouple front-end integration logic from UI components, making updates and debugging simpler.
  4. Testability: Modular adapters can be tested independently, ensuring reliable integration.
  5. Flexibility: Extend base adapters to meet specific domain requirements without disrupting existing workflows.
