Hybrid Approach
In the hybrid approach, we witness the best of both the above methods. The GraphQL server harmoniously interacts with a connected database while orchestrating data flow from existing systems.
- The hybrid approach combines elements of both the GraphQL server with a connected database and the GraphQL server that integrates existing systems.
- It offers the flexibility to interact with both local data stores and external services within a single GraphQL API.
- Consider a scenario where our application stores user profiles in a PostgreSQL database while leveraging external APIs for payment processing and email notifications.
- Resolver functions are tailored to handle data retrieval from the database as well as integration with external services, providing a comprehensive solution.
Example
Imagine a scenario where our book catalog GraphQL API not only fetches book details from the connected database but also incorporates external systems for user recommendations and reviews.
Javascript
type Query { books: [Book] recommendations: [Recommendation] } type Book { id: ID title: String author: Author genre: Genre } type Recommendation { id: ID book: Book user: User } type User { id: ID name: String } |
GraphQL Architecture
In the domain of modern web development, APIs serve as the backbone for data communication between clients and servers. Traditional RESTful APIs have long been the standard, but developers are increasingly turning to GraphQL for its flexibility, efficiency, and robust architecture.
In this article, we’ll dive deep into the architecture of GraphQL, exploring three distinct deployment methods:
- GraphQL Server With Connected Database.
- GraphQL Server That Integrates Existing Systems.
- Hybrid Approach with Connected Database and Integration of Existing System.
Let’s unravel the intricacies of GraphQL architecture and discover how it revolutionizes API development.
