enqueue_scripts()
Enqueues all of our scripts in a clean fashion.
public
enqueue_scripts([mixed $components = [] ]) : mixed
From each according to their capability, to each according to their need. Scripts are enqueued and localized using the following nested array structure: [ $unique_name_for_script => [ $name_of_api_component_to_use => [ $http_method1, $http_method2, ... ], 'dependencies' => [ $dependency1, $dependency2, ... ] ] ] This structure is then picked apart to dynamically enqueue and localize scripts. This gives us granular control over who gets access to what API endpoints, and can perform which actions, based on capability.
The scripts will be enqueued as: "cb_{$unique_name_for_script}", and will load a corresponding file, with the underscores replaced with dashes, like so: "cb-{$unique-name-for-script}.js". This will also load any dependencies found in the 'dependencies' array.
Scripts will then be localized using the same "cb_{$unique_name_for_script}" identifier, which will become the global name that is usable within the file. All API endpoints are localized as: "{$endpoint}_{$name_of_api_component}".
So, for example: - "cb_participation.get_participation" will return the API endpoint for getting participation entries ONLY when used within the cb-participation.js file. - "cb_core_admin.new_transactions" will return the API endpoint for creating a new transaction ONLY when used within the cb-core-admin.js file.
To access the API key, use "{$unique_name_for_script}.api_key" in the {$unique-name-for-script}.js file.
