When to use a filter vs a directive in Angularjs

Question

It\'s a simple question - and it may have been asked (just couldn\'t find it..)

When would you use a filter over a directive when it comes to manipulating the data, or v

Answer 1

Some hints (non-exhaustive lists):

Directive

Use it when...

• You want to do structural manipulation of the DOM
• You want to add behaviour (the controller)
• The outcome is dependent on other collaborators (the require configuration of the directive)

Filter

Use it when...

• You are transforming a value to another (e.g. String → Date)
• (Subset of the above, but important to warrant it's own bullet:) When you are transforming an array (e.g. to be displayed in repeated elements - the filter filter and ng-repeat)
