testdouble / maybe_later Public

Maybe you've been in this situation: you want to call some Ruby while responding to an HTTP request, but it's a time-consuming operation, its outcome won't impact the response you send, and naively invoking it will result in a slower page load or API response for your users.

In almost all cases like this, Rubyists will reach for a job queue. And that's usually the right answer! But for relatively trivial tasks—cases where the only reason you want to defer execution is a faster page load—creating a new job class and scheduling the work onto a queuing system can feel like overkill.

⚠️ If the name maybe_later didn't make it clear, this gem does nothing to ensure that your after-action callbacks actually run. If the code you're calling is very important, use sidekiq or something! ⚠️

If you're using Rails, the gem's middleware will be registered automatically. If you're not using Rails but are using a rack-based server that supports env["rack.after_reply"] (which includes puma and unicorn), just add use MaybeLater::Middleware to your config.ru file.
