Data Properties

Define reactive properties for your UI Wires with just a few lines of code.
Similar to Vue.js and other frontend JavaScript frameworks, you can define reactive properties on your Wires.

Defining Properties

You can define and initialize properties on your Wires using data.
component extends="cbwire.models.Component"{
data = {
"task": ""
};
}
Data Properties are parsed and tracked by Livewire and JavaScript, therefore only data types that are castable to JavaScript can be stored in Data Properties (strings, numeric, arrays, structs, or booleans). If you are needing more complex data types for your templates, use Computed Properties instead.
When data properties are mutated, the UI will update also.

Accessing Properties

Data Variable

You can reference a property using data.[propertyName].
component extends="cbwire.models.Component"{
property name="taskService" inject="[email protected]";
// Data properties
data = {
"task": ""
};
// Action
function addTask(){
taskService.create( data.task );
}
}

Getters

Getter methods are automatically available for your properties based on the property's name. You to access the property within your Wire using this.get[propertyName]().
component extends="cbwire.models.Component"{
property name="taskService" inject="[email protected]";
// Data properties
data = {
"task": ""
};
// Action
function addTask(){
taskService.create( this.getTask() );
}
}
You can use this as an alternative to using data.

Templates

You can reference data properties within your Wire's template using args.[propertyName].
<cfoutput>
<div>
<h1>Task</h1>
<div>#args.task#</div>
</div>
</cfoutput>

Resetting Properties

You can reset properties back to their original value using reset().
component extends="cbwire.models.Component"{
// Data properties
data = {
"task": "Some task here"
};
// Action
function resetForm() {
data.task = "Another value";
reset( "task" ); // Reverts data.task to 'Some task here'
}
}
There are several ways to use reset.
function someAction() {
reset( "task" ); // resets 'task' data property
reset( [ "task", "anotherprop" ] ); // reset multiple properties at once
reset(); // resets all properties
}

Security

Your component's private variables scope will hold your data property definitions and current values, but it's necessary to be cautious about what you store.
The values of your data properties are included with each XHR response and Livewire uses these values to determine what should be updated in the DOM.
You should NEVER store sensitive data ( such as passwords, and SSNs ) that you wouldn't want your application's users to see.
