HOW TO BUILD WEB APPS IN 2020 
Information technologies never stop evolving. In the tech world, each 
new year is not the same as the previous one. When 2019 is coming 
to a close, it’s about time to get up to date on the most popular web 
development technologies and the web development trends 2020 will 
be shaped by.
Businesses and web developers may feel challenged by the need to 
keep up with these continuous changes. The omnipresent 
competition, however, will not allow them to give up on the idea of 
improving the quality of anything that the business offers. Be it goods, 
services or an application as a medium for delivering them over the 
internet. A web presence has become a must and to turn your web 
app into a commercially viable digital product, you should develop or 
optimize it bearing some considerations in mind. In particular, you 
need to know what is popular among the global community of web 
developers, what makes it easier for them to implement software 
solutions, and what technologies drive the popularity of these 
solutions.
We’ve gathered 7 latest trends in web development and now are 
ready to share them with you. These trends are:
1. Progressive Web Apps and improved user engagement
2. Single-page web apps and improved performance
3. Motion UI and an enhanced design
4. Python, JavaScript, and WebAssembly
5. Hyper-automation and the power of AI
6. Voice search and improved SEO
7. Modules and lower web development costs
1. Progressive Web Apps and improved user engagement
It is impossible to talk about trends in web application development 
without mentioning PWAs. Although Progressive Web Apps have been 
around for several years now, in 2020, they will still remain one of the 
hottest trends in web development. It’s generally known that the faster 
web pages load, the higher they rank in Google search results. 
According to data recently revealed by Google, 53% of users abandon 
a site if it takes longer than 3 seconds to load. PWAs are modern web 
apps that can overcome this. They load like regular websites while 
preserving high-level functionality of applications. PWAs truly have the 
power to revolutionize mobile user experience and change the way 
business is done on the web. This positive change is fueled by the 
following progressive web app advantages:
• Re-engageable - Great performance improves user 
engagement and features like system notifications sent 
when users are not in the browser help drive re-
engagement.

• Shareable - each PWA has a specific URL linked to it, they 
are not published on official app stores.

• Discoverable - Progressive web apps can be discovered 
via search engines.

• Installable and lightweight - Users can add an app icon to 
their home screen without visiting an app store and an 
application itself won’t take much storage space.

• Network independent - PWAs use sophisticated APIs and 
are able to work across operating systems, including 
Chrome OS, Mac, and Windows. Also, they don’t depend 
on the network connection and can work in offline mode.

• Responsive - PWAs have user interfaces that fit all the 
phone, tablet and desktop screen sizes, which is enabled 
by technologies like media queries and viewport.

• Safe - Served over HTTPS, PWAs are reliable and secure.

• Cost-effective - PWA projects take up to 4 times less time 
to implement compared to native app development for iOS 
and Android, which also causes a substantial drop in the 
cost of development.

2. Single-page web apps and improved performance
The trend for having both a website and a mobile app is now in 
decline. For businesses, the idea of developing and maintaining them 
both seems unreasonable and resource-consuming. And not for 
nothing. It is reported that an average consumer downloads zero apps 
per month. Alternatively, the number of smartphone users worldwide is 
expected to keep growing. So, choosing to develop 1 quality app with 
a responsive design means substantially cutting down on expenses. 
There are two options here. Which one of the two to pick will depend 
on the needs and struggles of each separate business. Option number 
one is to go for a PWA that can drive mobile engagement and bring 
many other advantages we’ve mentioned. Option number two is to 
develop a mobile app and a simple single-page web app (SPA) to 
complement it. SPAs are JavaScript web apps that, instead of loading 
individual HTML pages from the server, load markup and data to 
dynamically render them on a single web page. This causes a boost in 
performance and eliminates the need for a user to reload a page. Still, 
there is a number of things you should know about the single-page 
app development:
• A development team must be familiar with JavaScript or 
TypeScript

• Single-page apps extensively use web APIs for performing 
most of the user interface logic rather than generating the 
logic in a server-side form

• SPAs are recommended when the app’s requirements 
cover complex user interface and rich functionality

In this regard, we should mention the API-first approach that will be 
trending in web development in 2020. Web solutions have to be 
connectable with other apps and devices, which has much to do 
with the rise of IoT. So, in the coming year, API development has to be 
perceived not as a side project but as the major focus of attention. 
API-first development means that a team creates an interface for their 
application first. After that, the team relies on the API that has been 
developed to build the rest of the application.
3. Motion UI and an enhanced design
Motion User Interface is one of the latest trends in UI development. It’s 
getting harder to hold users’ attention so that they could at least 
understand what your service or product is about. So, Motion UI has 
become and will remain a great attention-grabber that can satisfy the 
demand for interactive web design. This Saas library for creating UI 
transitions and animations for your web solution helps developers 
animate content without having a comprehensive knowledge of 
technologies like JavaScript, its frameworks and libraries. Motion UI 
components will enhance web application design, thus improving user 
engagement and app usability.
Another trend in UI/UX design for websites and web apps is that with 
the rise of mobile users, responsiveness has become necessary. 
Besides, it’s nice to know that you are on a par with such 
organizations as Apple, Adobe, Stripe, Booking.com, and Adidas in 
terms of responsiveness.
4. Python, JavaScript, and WebAssembly
Python. The present and the future of web development are defined 
by trending technologies like the ones we’ve already highlighted. But 
essentially, web development won’t be possible without programming 
languages. Python is the fastest-growing major programming 
language and one of the most popular web development technologies. 
In 2019, it has risen in the ranks of programming languages edging 
out C++ that was in the third position on the list a year ago but is still 
yielding to Java and C. Programming with Python in 2020 will still be a 
thing, as the language is general-purpose and can be used for quite a 
lot of objectives including web app development and scripting.
JavaScript. Another popular language, used to develop dynamic web 
apps, is JavaScript. Respectively, JS-based frameworks and libraries 
like Node.js or React.js have the power to enhance web development 
and make programmers’ lives easier. JavaScript, as an interpreted 
scripting language, is traditionally used for bringing interactivity to the 
world of web development and is one of three technologies behind the 
front-end of a website or web app. Now, however, embedded JS 
engines enable the extension of JavaScript to the server (Server-Side 
JavaScript) to extend the language capabilities as far as database 
access, remote web requests and more.
WebAssembly. While JavaScript is the most well-known scripting 
language for web pages, some developers may feel more comfortable 
using other languages for the browser. This is why WebAssembly has 
all the chances to finally have its breakthrough in 2020. WebAssembly 
is an open web standard that enables higher-level languages to run 
natively in the browser. Supported by four major browser engines: 
WebKit, Firefox, Chrome, and Edge, it is now paving its way outside 
the browser to run across different operating systems. Soon, it will be 
possible to code not only for the browser but also for Android and iOS 
in WebAssembly.
5. Hyper-automation and the power of AI
Artificial intelligence (AI) and machine learning (ML) now lie at the 
core of nearly any digital transformation or technology innovation, so 
2020 will be a year of their prominent growth in web development as 
well.
Accuracy, speed, and reliability that artificial intelligence provides help 
automate every task. The automation of processes is trending in web 
development as is all over the tech world. It can make web 
programming easier by eliminating the need to write repetitive code, 
but it can also make development take longer. On one hand, AI 
algorithms can help find the right solutions faster. On the other hand, 
there is the whole issue of complexity. Complexity is where you need 
an experienced developer to make your site more robust. The 
automation aspect also depends on what your site is. If your site is 
mostly text, you will need an automated editor to generate the code 
you will need to write. If your site is a bit more dynamic, or you have a 
mobile site, then the automated editor is even more essential. If you 
have multiple languages, or are making a mobile app, then you will 
need a separate editor for each.
Automation is a big business in the world of web development, so 
don't think of it as a threat to the quality of your web apps or services. 
It does not also mean you have to give up your craft. Automation is 
great because it means you can create more complex and robust web 
applications and services without the need for an engineer to program.
AI can automate not only the website or web app making process but 
the entire business. Summing up what has been said, let’s define in 
what ways AI can complement your web development efforts:
• Automated data collection by using AI-powered chatbots
• Improved user experience with intelligent chatbots
• Accurate customer behavior analysis
• Web coding replaced by self-learning algorithms
• Enhanced software testing & QA
• Email marketing automation
• Customization of search results for users
6. Voice search and improved SEO
Not only voice assistants have become a common feature of 
smartphones, but also search by voice has exerted a significant 
impact on web development as such. Voice assistants have the 
capability of allowing a user to interact with their computer or mobile 
phone by providing them with the ability to perform a search, create an 
email, call someone, find out the weather, or other various services. All 
of these functions are done through voice input.
Voice search is a feature of the web that allows a web browser to 
search the web for a keyword that was entered. It's used to quickly 
find information on a page, in a web browser or even from a desktop 
search bar. As one of the current trends in web development, the 
voice search is becoming the de facto method of finding pages with 
needed results. In short, the web has undergone a dramatic shift in 
usage of voice search so that it's becoming an integral part of how 
users interact with the web.
As a result, businesses start increasing their investment in content 
marketing and voice search optimization for search engines, Clutch 
claims. They realize now that voice search can be a lucrative 
opportunity to acquire new users. This, in turn, can lead to more 
organic search traffic and conversion. As a result, businesses are 
shifting their search marketing efforts from traditional display to voice 
search.
When touching the technical side of the issue, we’d mention Web 
Speech API that allows businesses to create voice-powered 
applications. Web Speech API uses artificial intelligence and machine 
learning to allow a service to automatically read out content based on 
user interaction. The big deal is that the technology can be built into all 
web browsers: Chrome, Firefox, Safari, Internet Explorer and others. 
So, what's the potential? Well, there is plenty of possibilities to provide 
better voice services for people in 2020. Google's Web Speech API is 
still young and it's possible that there are some problems with it, but 
you can expect to see the technology powering more and more 
websites over the next few years.
7. Modules and lower web development costs
Modular design is among the web development trends that will 
continue to dominate in 2020. And it’s happening for a reason. 
Modularity offers the following advantages to development teams:
• It allows for a simpler and more effective web application 
architecture.

• It helps to write less code and maintain a better quality of 
an application.

• It can improve your development time and help you 
manage your projects better.

• It allows creating smaller, faster and leaner code bases.

The modular web application architecture is simple and elegant. It will 
eliminate unnecessary latency, scalability concerns and complexity. 
With a simple system like this, developers will no longer need to be 
able to understand all the intricacies of a large application, which is a 
huge amount of overhead that they simply cannot justify in the end.
With a web site or web app reduced to their components, it will be 
much easier for web developers to navigate. In this way, the 
development process will be more flexible, take less time and the 
development costs will go down, too.
