During the development of a large meteor application, I noticed that many helpers were unused and hanging around until someone figured out it was time to delete them.
This package inserts itself between Meteor and your helpers. It provides a function you can call to get a list of helpers that were never used.
meteor add froatsnook:zombie-helpers
Start your application and use all the features you can. This ensures that helpers aren't marked as zombies just because you forgot to render a particular template.
Package["froatsnook:zombie-helpers"].ZombieHelpers()
// => ["Template.welcome.helper1", "Template.welcome.helper3", "Template.xyz.helper4"]You can also provide a template name to just get a list of zombie helpers for that template:
Package["froatsnook:zombie-helpers"].ZombieHelpers("xyz")
// => ["Template.xyz.helper4"]Go through the potential zombies, make sure they aren't used, delete them, and forget them.
This package is debug only. That's why the ZombieHelpers function can't be accessed except through Package. It also means that it won't cause any slowdown when you run in production (not that it should ever cause a noticeable slowdown when not in production).
It overwrites Template.prototype.helpers and replaces each of your helpers with another function that increments a count for that helper before calling the original helper. That's it!
- Add a UI that displays helpers per template sorted by usage count.
- Tests
