initialisation code is executed **each time** ReactJS::getMarkup() is called. I cannot see a good reason why this should be the case, and my thinking is that the concatenated code bundle should be executed once only - when ReactJS is instantiated. This way, ReactJS::getMarkup() is only responsible for executing the JS React.renderToString() method, rather than executing the whole vendor bundle first, and then calling .renderToString() - which is incredibly costly and slow!

I think this makes sense and is pretty similar to what we do in react-rails. Let's do it. |

The fix addresses an issue where the concatenated Javascript initialisation code is executed each time
ReactJS::getMarkup()is called. I cannot see a good reason why this should be the case, and my thinking is that the concatenated code bundle should be executed once only - when ReactJS is instantiated.This way,
ReactJS::getMarkup()is only responsible for executing the JSReact.renderToString()method, rather than executing the whole initialisation bundle first, and then calling.renderToString()- which seems to be incredibly costly and slow!This change dramatically speeds up things for me on pages with multiple separate calls to render React components.
