Drupal Support for Accessibility for the visually impaired

There are many Accessibility support javascript plugins, start with the free module and then, on the same way you can integrate other javascript support.

Step 1: Build your custom module that support accessibility

create a custom module, this module should include the following folder structure and files:

• my_module
  • assets
    • js
  • my_module.info.yml
  • my_module.libraries.yml
  • my_module.module

The folder 'js' should contain the accessibility javascript support, I used NagishLi: Accessible Internet for Free

Download the plugin and extract it, the output will be folder name: nagishli-files and nagishli_beta.js
puth both in your module folder: js

your module folder now will look like the following:

• my_module
  • assets
    • js
      • nagishli-files
      • nagishli_beta.js
  • my_module.info.yml
  • my_module.libraries.yml
  • my_module.module

Step 2: Set your my_module.info.yml

name: my_module
type: module

package: System
core_version_requirement: ^10 

Step 3: Set your my_module.libraries.yml

Add the following code into the module libraries configuration

nagishli:
    js:
        assets/js/nagishli_beta.js: {}

Step 4: Set your module file, which will upload the script with module

    function rw_page_attachments(array &$attachments) {
        $attachments['#attached']['library'][] = 'rw/nagishli';
    }

you are all set.

don't forget to: clean the site cache and clear browser cache
