You might know resource hints (http://caniuse.com/#search=Resource%20Hint) which are used by browsers to preload/prefetch stuff before it is needed. Since I’ve been started applying the approach into some sites, I was looking for sort of a solution which can gather info from my site and add hints to browsers (yeah, I don’t like manual work), but it looks there is any, hence, I thought of creating an engine https://github.com/sirko-io/engine to achieve my goals. Currently, it only adds the prerender hint (the browser prerenders the page before a user visits it), but I got more plans for the project. If you try to solve the same challenge or you want to use my solution, please, contribute or try it or leave feedback. Any help or advice is priceless. Thanks for your attention!
