To be clear, Server Push as described in the article is not actually provided by nginx yet and thus by the server config in the article. I have no doubt that the awesome nginx folks will implement in due time though.

Its implementation is already present in nginx plus since 2015. https://www.nginx.com/blog/http2-r7/ https://www.nginx.com/blog/http2-r7/ Not sure if they are going to provide server pushes in the community version soon.

  From your link: >The “Server Push” feature defined in the HTTP/2 RFC is not supported in this release. Future releases of NGINX Plus might include it.

    Does not invalidate his main point: the developers have a conflict of interest into releasing features for the open source version that competes with the paid version.

      My reply wasn't intended to. I was pointing out that even the Plus version doesn't have Server Push. I don't expect it will ever be present in the open source version, barring a fork.

I'm not sure they will ever implement it actually. Nginx does not support HTTP/2 server push as of March 2017 (v1.11). Owen Garrett at nginx has summarized the reasons as follows: - it is a non-essential and optional part of http/2 - if the client already has the resource cached, then by pushing it to them you might be unnecessarily wasting bandwidth. - server push spec might change in the future. - Link headers as hints is useful, but usage has been low from web developers. - server push has been available as part of SPDY and was not utilized by many web developers. Read his original comments here[1]. This table[2] accurately describes the pro's and con's of server hints vs server push. Personally this disappoints me because I think this would be a valuable feature for web developers willing to invest the time to optimize page speeds. I also know that some large CDN's like Cloudflare have implemented their own version within nginx to optimize page downloads.
