One Time Binding for Interpolated Value in Aurelia

Question

Is there a way to change the default one-way binding of an interpolated value (e.g. ${someValue}) in the view to one-time?

Something like the angularjs {{::someValue}}

Answer 1

For the benefit of developers still looking for a solution to this, the feature is now implemented using binding behaviour. You can use ${someValue & oneTime} to get one time binding of the interpolated string. Alternatively you can use normal binding syntax like this value.one-time="someValue"

Answer 2

From Rob Eisenberg via Gitter channel:

There will be a way to do that once we implement binding options.

There are a variety of options for bindings we want to add such as : trigger, signal, mode, etc.
