A simple module demonstrating how to export node as JSON data using dependency injection
This module needs to alter the existing Drupal "Site Information" form. Specifics:
- A new form text field named "Site API Key" needs to be added to the "Site Information" form with the default value of “No API Key yet”.
- When this form is submitted, the value that the user entered for this field should be saved as the system variable named "siteapikey".
- A Drupal message should inform the user that the Site API Key has been saved with that value.
- When this form is visited after the "Site API Key" is saved, the field should be populated with the correct value.
- The text of the "Save configuration" button should change to "Update Configuration".
- This module also provides a URL that responds with a JSON representation of a given node with the content type "page" only if the previously submitted API Key and a node id (nid) of an appropriate node are present, otherwise it will respond with "access denied".
