Background Worker Example

This example shows a common scenario where an application has a running API and some kind of background worker doing its own tasks. It is useful to be able to shut down the API and the background worker gracefully. This demo shows two ways that this can be achieved with babyapi:

1. Use WithContext() to pass a context.Context to the API. This allows the API to shutdown when the context is cancelled. Use this context in the background worker as well to easily shut it down also

   • This example will automatically shutdown using a context cancellation after 5 seconds. Simply run go run main.go serve and let it run to see this in action

2. Use api.Done() similarly to ctx.Done() so the background worker can automatically shut down when the API is stopped

   • When using api.RunCLI(), the API can be stopped using Ctrl-C, so run go run main.go serve followed by the Ctrl-C keystroke to see the background worker gracefully shutdown as well

Both of these methods will also work if you are using api.Serve(addr) instead of api.RunCLI(). Just replace Ctrl-C in the second example with a call to api.Stop() from another point in your code.
