Hello. Future development under React is planned.
Interested in the question, how are things with SPA applications and their indexing in 2018?
What current best practices exist now? In particular, I studied in React
Notes from Google / Yandex, but I would like to hear about real experience over the past few months.
I remember there was news from Google (in November 2017) that they rewrote their manifesto from 2009. The new edition says something like this: "We give a free hand to all WEB developers and claim that we can parse any sites with JS." If so, please share your experience. Thanks
