Collection of helpers to aid in reactive template programming with Ember.js.
Reactive helpers are helpers that return functions. These functions can be bound to event handlers
to process data on the way up in the Data Down Actions Up cycle. r
helper makes it possible to use
ember-composable-helpers
in event handlers where execution of the helper is delayed until event is triggered.
Returns a function for a given helper and curry arguments to it.
r
helper accepts functions as helpers. For example, lets say you have a method on the context called addNumbers
export default Ember.Component.extend({
addNumbers([a, b]) {
return a + b;
}
});
You can use it in the template.
(r/get)
helper returns a function. When called, the function will return value taken from object that it receives as first argument at property propName.
(r/param)
return a function. When called, this function will return received argument at specified index.
(r/debugger)
will create a helper that will inject a debugger breakpoint into a helper pipe. It will pass through the value,
that's passed into the helper.
(r/log)
helper will evaluate to a function. When called, this function will log the passed in messsage and arguments that it received.
(r/tap value)
helper will evaluate to a function that'll return the passed in argument.
{{shhh
helper will supress any output that's passed into it. This is useful when you want to compute a helper
without having it's output rendered.
(transition-to)
helper the same argument signature as link-to
but evaluates to an action that can be called to trigger transition.
(throttle)
helper will ensure that the action is only triggered once per given wait period.
The action will be triggered at the end of the wait period unless immidate
is set to true.
(debounce)
helper waits for specified time to pass before triggering callback. All intemidiate events are discarded.
