Adding extra 'opts' data to the "DiscourseEvent.on(:post_created)" event from javascript?

I’m not entirely sure what you’re trying to accomplish, but what I think you need is:

In an initializer (i.e. assets/javascripts/discourse/initializers/initializer_example.js.es6):

import Composer from 'discourse/models/composer';

export default {
  name: 'initializer_name'
  initialize() {
    // this adds your property to the attributes serialized to the server by the createPost method in the composer model
    Composer.serializeOnCreate('your_property');

    withPluginApi('0.8.12', api => {
       api.modifyClass('model:composer', {
          // set your_property here, or modify the composer controller and set it on the model there instead
       })
    })
  }
}

In plugin.rb

after_initialize do
   add_permitted_post_create_param('your_property')

   DiscourseEvent.on(:post_created) do |post, opts, user|
     # opts[:your_property] is available.
   end
end

For an example, see my events, ratings or locations plugins.
