uiRegistry

uiRegistry is a in-memory storage, plain storage of entities by keys. Implements the get(), set(), and has() methods.

JS debugging using uiRegistry

To debug the UI component JS, we first need to get a uiRegistry instance from the browser console. To do so, use the RequireJs ID uiRegistry.

In the browser console enter the following:

1
var registry = require('uiRegistry');

Now we have uiRegistry instance in the registry variable. We can use it to get an instance of any component.

1
var component = registry.get('%componentName%');

The uiRegistry instance allows you to search for components using property values. If you know a unique property value of a component that you need to find, you can use the following code to get the component:

1
var component = registry.get('%property% = %propertyValue%');

Examples

The following code shows how to get a component by a full component name:

1
2
// Admin > Products > Catalog > Add Product
var fieldName = registry.get('product_form.product_form.product-details.container_name.name');

The following code shows how to get a component by a property value:

1
2
3
4
// Admin > Products > Catalog > Add Product
var fieldName = registry.get('index = name');
// or
fieldName = registry.get('inputName = product[name]');

The previous example gets the same JS component as using the full component name.

Lets look what we have in component variable. It keeps component context with all properties, we can see component file, component name and so on.

console.log(fieldName.name); // product_form.product_form.product-details.container_name.name

fieldName.trigger('validate'); // will invoke validation
fieldName.visible(false); // will hide field from page
fieldName.visible(true);  // will show field again
fieldName.value(); // will show current field value
fieldName.value('New string value'); // will change field value to string 'New string value'
