PWA is one of the most influential trends in the web development community. This propels the web onward, thus making the browsing experience on a website much closer to built-in mobile applications, and it is more friendly to users.
With PWA, it will push the envelope, and more than 80% of users spend most of their time on gadgets.

AMP is the technology created to encourage building websites that load fast and work smoothly across all devices. The time it takes to load is about 2 seconds and up 22 seconds for non-AMP pages.
With AMP, I believe the website loads and works fast, and our technology will evolve into a 3D world when looking at websites on our gadgets.

With the web development trends overloaded with all types of new tech like PWA and AMP, RWD is still on the scene. The only significant difference is that it was a remarkable feature many years ago, a must-have feature. With the more and more mobile devices out there, the majority of people use their mobile-first. Google is planning to add mobile-first indexing. Understanding that, the website ranking depends on its ability for optimized mobile phones.
RWD is going to keep on going as website design starts with mobile-first. RWD will always be around. I think it will evolve into something more spectacular, like working more 3D imagery.

VSO is another nifty trend that nobody should overlook. This trend is having a tremendous impact on the web, and yet there will be more coming. According to Gartner, about 30% of all searches will be done without using a screen by 2021. With that being said, the number of smart speakers is climbing every year. VSO is a simple something you can’t ignore. This VSO should become part of everybody’s SEO and tech strategy. People that adapted to this will be ahead of the competition.
VSO will evolve with everyone using gadgets like Alexa, Google, Nest, Apple, and much more. Speech recognition is multiplying, and the improvements with picking have evolved over the years. I use speech recognition just on a few devices, but now that the technology has gotten much better, it picks up your voice clear as a bell.

The current trends in website development suggest that web solutions have to be well-prepared for connectivity with other applications. It’s no surprise considering the rise of mobiles, wearables, and other devices that should integrate. That’s where the tendency for an API-first development approach comes from in this approach.
What’s wrong with the traditional system? When a company’s primary focus is to build a web or mobile solution, they usually don’t pay much attention to API development. At best, it comes as a side project that might not be adequately designed and tested.
