Streaming SSR #322
Comments

With React 15.x using React-Helmet, since I stream the document head for prefetching before performing any SSR work, my work around was to cache the meta tags / title results from react-helmet after render. Is there a way to rewrite head later in the document? |
Nopesies, the browser already has that part so you can't change it anymore. That's what this issue is about... 😉 |

React 16 introduced streaming server-side rendering, allowing Node servers to improve the TTFB and respond better to backpressure. Unfortunately, how react-helmet works at the moment it doesn't lend itself to streaming at all since the
document.headis already at the client by the time helmet knows what meta tags to inject.I wanted to kick off a discussion about how dynamic meta tags could work in this new streaming world. Has anybody given this any thought?
