QUESTION
The code below is the one I am using for plotting an LDA plot using text2vec inside topic_model function in a shiny app. input$date is a checkboxGroupInput selection, input$data works perfectly fine for a DT::renderDataTable output & topic_model runs well outside the app. Here I found how to get an LDA plot in a shiny app, but I didn't really get it so copied as it was. input$go is a simple actionButton.

Also eventReactive looks wrong. It's not doing anything. Did you mean:

I'm new to ReactJS and I would like to communicate between my components. When I click an image in my "ChildA" I want to update the correct item image in my "ChildB" (type attribute in ChildA can only be "itemone", "itemtwo", "itemthree" Here is what it looks like
Parent.js
...ANSWER
Answered 2019-Jan-11 at 18:13What you need is for Parent to pass an event handler down to ChildA which ChildA will call when one of the images is clicked. The event handler will call setState in Parent to update its state with the given value, and then Parent will pass the value down to ChildB in its render method.
You can see this working in the below example. Since I don't have any actual images to work with—and to keep it simple—I've used s instead, but the principle is the same.

QUESTION
I'm a JavaScript newbie and I'm trying to create a web application with three AMD modules - Parent, ChildA & ChildB. The Parent module has a KO observable which stores the parent's name. Both the child pages should be able to read the Parent's name. But I don't want to add a dependency between the Parent and the Child modules. Instead, I want to store the Parent's name in a globally shared object which can be accessed by all three modules.
Currently, this object stores the value of Parent's name and all the modules are able to access it. But whenever I make any changes to the Parent's name, the change is not getting reflected in the Child modules. Only the Parent module can change the Parent's name and I want the child modules to be synchronized with the changed Parent name.
Since the Parent's name is a KO observable, I can add the Parent dependency to the child modules and subscribe to the changes. But I'm trying to avoid tight coupling between these modules.
Code with tight coupling between modules (which i want to eliminate):
