What are the best practices for using the Ruby Async gem?

When using the Ruby Async gem, it's important to follow a few best practices: 1. Use async blocks to manage concurrency effectively. 2. Avoid blocking calls within async code. 3. Leverage the built-in error handling to manage exceptions gracefully.

Can you explain how to handle errors in async code?

Certainly! In async code, you can use the Async::Task class to wrap your operations. This allows you to catch exceptions using the rescue block, ensuring that errors are handled without crashing your application.

What are some common pitfalls to avoid?

Common pitfalls include mixing synchronous and asynchronous code, which can lead to unexpected behavior. Also, be cautious with shared state; use proper synchronization to avoid race conditions.

How can I test my async code effectively?

To test async code, use testing frameworks that support async operations, like RSpec with the async matcher. This allows you to write tests that can wait for async tasks to complete.
