I recently came across a great article by Shiju Varghase about web development trends prevalent in 2015 which will also continue forward for years to come. Although the article was written in mid 2014, the content and technologies mentioned as still very relevant. Another reason I reference this article now is because many of the technologies mentioned were very new at the time when the article was written but now they have a much larger presence and there is much more material to explore if you want to dive deeper. I would highly encourage you give this article a read.
