How to implement integrations in applications with clean architecture?

Modern applications require sophisticated integrations to interact with other systems and services. Whether it is sending notifications, managing files, or communicating with other services, an effective implementation is crucial. Clean architecture offers an orderly approach to these integrations, allowing the cohesion of the system to be maintained without compromising its structure.

What are common types of integrations?

1. Sending messages: Applications send emails, text messages, push notifications, among others. These notifications can alert users to important events, such as the availability of a new report or changes to their account.

2. Reading and writing files: Saving files to disk or to the cloud is part of the integrations. Using storage in services such as Amazon S3 replaces local storage, keeping the business logic independent of the technology used.

3. Communication with other services: This includes the use of REST APIs, messaging queues or remote procedure invocation (RPC). These integrations allow services to exchange data efficiently.

What is a design pattern and how does it help?

Design patterns are proven solutions to common problems in software development. Among the 23 original patterns, the Adapter Pattern is essential for integrating incompatible interfaces.

The Adapter Pattern consists of:

• Converting an interface into another compatible interface.
• Acting as an intermediary between the client and the adaptee, which is the particular implementation we want to use.

How does a code example help to understand the integrations?

In the Spring Boot implementation for airlines, we create a WeatherAdapter interface. This sits in the domain and abstracts the details of how the weather information is obtained.

For example:

 {public interface WeatherAdapter { Weather getWeather(String location);}

This adapter interacts with well-known services such as Open Weather Map to obtain weather forecasts. It is important to respect the interface while adapting details such as the API URL or the access key. This abstraction ensures that the domain is not affected by the way the information is obtained.

What are the recommendations for the use of design patterns?

When implementing software integrations:

• Use the right pattern for each problem.
• Keep business logic separate from integrations.
• Consider using dependency injection to handle specific implementations.

What additional resources are available?

To go deeper, we recommend exploring the design patterns course that provides more detail on the Adapter Pattern and other patterns. Learning these tools will expand your skills in designing clean and efficient software.

Learning how to effectively integrate different services will strengthen your applications, preparing them to respond to today's technological demands. As you progress, try implementing the Adapter Pattern in your projects and share your experiences.
