<p>Something interesting that <a href="https://www.daveliddament.co.uk">Dave Liddament</a> and I discussed was the use of value objects in application code.</p>
|
|
|
|
<p>Instead of using a primitive type, such as <code>string</code>, you can create a new value object for a specific type of string, such as an <code>EmailAddress</code> or, in my side project, a <code>LicenceKey</code>.</p>
|
|
|
|
<p>Both are strings, but using value objects of specific types can make the code more readable and its intent clearer.</p>
|
|
|
|
<p>A value object can contain additional logic, such as validation to execute an ensure the value object is valid, such as making sure a string is not empty, is a specific length or only contains valid characters.</p>
|
|
|
|
<p>This an approach that I'm going to use more going forward.</p>
|
|
|
|
<p>I also found <a href="https://www.youtube.com/watch?v=yJpvObzKewY">a lighting talk by Dave</a> at a PHPSW meetup where he explains this further and, of course, you can listen to the podcast episode after it's been released.</p>
