Module development and code questions

I try to port a module that i want to publish, to Drupal 11. 

There have been some changes to the API and i cant get it to work at all. It must be some small detail in namin of something.

I still get:

• 'elif_nofollow' is not a supported key.
• 'elif_noopener' is not a supported key.
• 'elif_noreferrer' is not a supported key.

I have a custom text filter like this:

What are the best ways to audit and review a custom module (or a contrib module) to ensure it is secure, or at least follows best practices?

Hello

I try to add a link appear in /admin for a specific role. This specific role has a few permissions (adding specific content for example) and I would like to hide certain links appear in /admin and to add other links in this same page.

I tried to use the hook MYMODULE_page_attachments_alter but I did not find the way to add links into this.

What solution for this ?

Thanks

What are the steps to follow to add new exposed filter widget for a JSON field added using the Views JSON Source module?

Overview

PHP 8.1 introduced a new data model, Enumerations. Enumerations allow for the creation of custom data models that can only contain a fixed set of allowed values. These enumerations can be very useful when working with Drupal list fields, which are a field type that allows for selection from a predefined set of values. As both enumerations and list field contain a predefined set of values, using Enumerations to back Drupal list field makes for more stable code that is easier to understand, and less likely to fail. 

I'm developing a Drupal 10 website with the DXPR Builder default theme and have two views that combine Flex Slider with the content events module to display events. My goal is to:

1. Display the first slider for both anonymous users and logged-in users.

2. Display the second slider only for logged-in users who have specific roles (e.g., admin, manager, content creator).

I've attempted to achieve this using Contextual Filters, but I haven't been able to get it to work as expected.
