I have a CSR react application running on port 3000. Now I need to create SSR app for this. I created a new server running on port 3003 and the server returns html template as expected. But the returned template is not a react app. react devtools not detecting and javascript event handlers are not working. I know I need to hydrate the html template from server. but i don't know the right place to invoke ReactDOM.hydrate(). Should I invoke this in the server application? Because i am accessing the port 3003 for SSR.
