title: React-Redux - broadcasting an action to components
body: <p>I have currently an issue of which I am unsure if I am just not seeing the bigger picture (or possibly not do this at all) or if this is valid in redux...</p>
  
  <p>I have an SVG chart with a fixed size. It can happen that the user opens a panel on my page which will reduce the width of the chart. This leads to my chart looking compressed. To fix this the chart should rerender with updated dimensions so everything looks good again.</p>
  
  <p>So... I have a component that the user clicks in order to open the panel. That component should trigger an action, ideally something general and reusable like "rerenderSVG". I could use the standard redux workflow and have my reducer put some flag in my state and have all my svg-related components listen to that. But that feels like overkill. This is nothing I want in my state, I only want an action that is broadcast to all my mounted components, like "hey, components, this just happened, if this concerns you: please react".</p>
  
  <p>This can be easily done in flux, but in redux... I don't know. Can this pattern be implemented and still be in accordance with the redux way?</p>
  
  <p>And if this problem is so mundane that there are already thousands of posts on this: Sorry! But I didn't really know for which keywords to look...</p>
