Prevent deprecated template lifecycle callback assignments (no-template-lifecycle-assignments)

Assigning lifecycle callbacks to template properties has been deprecated in favor of the more robust template lifecycle callback registration functions.

Add onRendered, onCreated, and onDestroyed methods to Template. Assignments to Template.foo.rendered and so forth are deprecated but are still supported for backwards compatibility. -

Rule Details

This rule aims to ensure you are not using deprecated functions to register lifecycle callbacks to templates.

The following patterns are considered warnings:

js

Template.foo.created = function { /* .. */ }
Template.foo.rendered = function { /* .. */ }
Template.foo.destroyed = function { /* .. */ }

Template[bar].created = function { /* .. */ }
Template[bar].rendered = function { /* .. */ }
Template[bar].destroyed = function { /* .. */ }

The following patterns are not warnings:

js

Template.foo.onCreated(function { /* .. */ })
Template.foo.onRendered(function { /* .. */ })
Template.foo.ondestroyed(function { /* .. */ })

Template[foo].onCreated(function { /* .. */ })
Template[foo].onRendered(function { /* .. */ })
Template[foo].ondestroyed(function { /* .. */ })

When Not To Use It

This rule should not be used with Meteor below v1.0.4.
