Q: Go Trigger vs eventbus libraries in Go?

Go Trigger is minimal and focused on global/local events with a simple API, while libraries like eventbus might offer more features like wildcard matching or persistent events. Pick Go Trigger for lightweight needs and eventbus for advanced functionality.

Q: How to test events registered with Go Trigger?

Mock the trigger instance or use dependency injection in tests. Since events can be global, clear state between tests using ClearEvents() to avoid leakage, as shown in the available methods.

Question 1

How to handle multiple event handlers for the same event in Go Trigger?

Accepted Answer

Currently, Go Trigger only supports one handler per event, as mentioned in the under-development features. For multiple handlers, you'd need to implement a wrapper function or wait for future updates that add this capability.

Question 2

Is Go Trigger better than using native Go channels for events?

Accepted Answer

Go Trigger offers a higher-level abstraction with string-based event IDs and global registration, which simplifies decoupling, while native channels provide more control and type safety. Choose based on whether you need simplicity or fine-grained concurrency management.

Question 3

How to pass structs or complex types as parameters in Go Trigger?

Accepted Answer

You can pass any type via the params in Fire(), but since it uses reflection, ensure the handler function expects compatible types. For example, use trigger.Fire('event', myStruct) and define the handler to accept that struct.

Question 4

How to ensure background events finish before my Go program exits?

Accepted Answer

Use the channel returned by FireBackground() to wait for completion (e.g., <-channel), or implement synchronization like sync.WaitGroup, as the README cautions that background events may stop if the program exits early.

Question 5

Go Trigger vs eventbus libraries in Go?

Accepted Answer

Go Trigger is minimal and focused on global/local events with a simple API, while libraries like eventbus might offer more features like wildcard matching or persistent events. Pick Go Trigger for lightweight needs and eventbus for advanced functionality.
