How to Design a Well-Structured API with Both Async and Non-Async Options?

Build a well-structured API with both asynchronous and synchronous options

In the field of software development, designing APIs that support both synchronous and asynchronous operations is a challenge. When dealing with methods involving network I/O, it is necessary to provide a user-friendly interface while maintaining high performance.

Asynchronous and synchronous methods

Asynchronous methods have the advantage of non-blocking operations, allowing code to continue executing without waiting for a network response. Synchronous methods, on the other hand, block the thread until the network operation is completed, which may affect the overall responsiveness of the application.

Design points

To effectively provide asynchronous and synchronous options, it is important to consider the following aspects:

• Implemented separately: Implementing asynchronous and synchronous versions of the same method can lead to code duplication and maintenance issues. It is recommended to create different methods for each operation.
• Avoid blocking calls: Asynchronous methods should not make any blocking calls or use thread pool threads, as this will negate their effectiveness.
• Wrapping methods: Wrapping an asynchronous method in a synchronous function is not an ideal solution as it introduces additional overhead and performance penalty.

Boolean parameter skills

One possible way to combine asynchronous and synchronous functionality is the "boolean parameter trick". This technique involves adding a boolean parameter to the method that determines whether the operation should be performed asynchronously or synchronously. The implementation can then dynamically decide to call the appropriate internal method based on this parameter.

Summary

Designing effective asynchronous/synchronous APIs requires careful consideration of the above principles. By adhering to these guidelines, developers can create user-friendly and performant APIs that meet the various needs of users.
