Standards in web development sometimes change faster than they can be implemented. To stay one step ahead, it is important to focus on trends, techniques, and approaches that are gaining popularity.

We have analyzed tendencies across industries to create this ultimate list of web development trends in 2019. As a bonus, you’ll read about the top web technology stacks worth your attention in the coming year. No matter what your current interests are: marketplace development, startup innovations or IoT inventions, you should be aware of these trends.   

We won’t waste any more of your time. The trends are here:

Voice search in web development

Voice search

We are currently experiencing the beginning of the voice search era. Every smartphone is already equipped with a digital voice assistant (Siri for iPhones, Google Assistant for Android-based phones). Moreover, smart speakers empowered with AI are gaining popularity.

What is the reason behind this shift toward voice interfaces?

  • Ease of use
    Communication is something we don’t have to learn. Therefore, children and elders can interact with voice interfaces without any learning curve.  

  • Affordability
    Digital voice assistants are a common smartphone feature already. Smart speakers are not that common yet, but a price tag starting at $50 is a great prerequisite for expansion.

Voice search is one of the main trends in e-commerce. However, it is also applicable to all businesses across the web. If you want your web app to be found, optimize it for voice search as soon as possible.

By 2020, 50% of all searches will be done by voice.

Also, consider developing your own application for smart speakers. This will give you one more channel for building a loyal audience and generating sales.


When building a web app, performance is usually compromised. JavaScript limitations make heavy calculations slow, and that significantly affects user performance. This is why most popular games and powerful applications are only available as a native desktop app.

WebAssembly is here to change the game. This new format aims for native-like performance among web apps. With WebAssembly, the code in any programming language can be compiled into bytecode that runs in a browser.

WebAssembly code is executed faster than Javascript. As a result, you can write the performance critical parts of the app with the most suitable language (C/C++/C#/Rust/Kotlin, etc). WebAssembly will then take care of execution in the browser. Native apps can be run in the browser right away. That means access to more users while offering comparable performance on the web without additional development expenses!

The main issue with WebAssembly is that some browsers don’t support it yet. However, that will change soon.

Web apps are becoming more powerful with WebAssembly. This technology is definitely worth trying out.

Machine learning in web development

Machine learning

Artificial intelligence, including machine learning, affects our everyday activities on the internet without us even recognizing it. This is the main point of machine learning - providing improved experiences natively.

Machine learning is the ability of software to improve performance without direct input from developers. Basically, the software analyzes incoming data, detects patterns, makes decisions and improves its work.

Airbnb, for example, employed machine learning to customize search results for guests to increase the chances of host acceptance of their request. A machine learning algorithm analyzes the request acceptance decisions of each host. Depending on it, the search results listings that are more likely to be accepted rank higher. A/B testing has shown a 3.75% increase in conversion. As a result, all Airbnb users are now treated according to this algorithm, which improves customer satisfaction and increases revenue.

Great example, isn’t it? But there’s so much more! Enabling natural language and image recognition can improve user experience. Machine perception allows the computer to interpret data and make grounded decisions. Machine learning is being used in web apps in different industries, such as healthcare, finance, education, agriculture, etc. This technology offers significant improvements that would be difficult to achieve without AI.

Machine learning is becoming a significant part of any web service. It’s important to integrate it into your services as well! Analyze your website visitor behavior and adjust the content they are shown. 

Your visitors won’t ever find out that you’re using an algorithm, but their satisfaction will result in an increase in engagement and conversion!

Machine learning can be your secret weapon to outplaying your competitors!

Data security

The more data that a web app processes, the more attractive it looks to cybercriminals. They aim to spoil your services and steal your users' data or internal company information. This can cause great harm to your reputation and cost you a lot.

Your web service security should become a top priority. So, to keep user data safe in 2019, follow these tips:

  • Never neglect security testing
    Security testing can be conducted during the development stage and can prevent data leakage. Each change in your web app should be explicitly tested.

  • Use website monitoring tools
    An algorithm can constantly monitor all requests, as well as detect and qualify suspicious activity. A timely notification enables your team to instantly react and protect the web app.

  • Carefully choose third-party services
    SaaS software is becoming more popular as it makes app development easier and faster. However, you have to make sure that the service provider you choose to work with is trustworthy.

  • Encrypt sensitive data
    Even if the offender gets to your database, they won’t be able to extract any use from the sensitive data stored there.  

Blockchain in web development


Even though blockchain has lost some trust due to unstable cryptocurrency exchange rates, we have to admit it: this technology is here to stay. Though it originated in the desktop realm, blockchain is quickly expanding to the web.

Blockchain wallets have shifted from native desktop apps to web apps. They are perfect for storing small cryptocurrency amounts and offer improved ease of use. As the popularity of web wallets continues to rise, you should consider this sphere.

Another blockchain implementation is called dapps, or decentralized apps. The unique feature of apps like these is server-database logic storage in blockchain. As a result, no single authority controls the application (such as Facebook, Google, etc.).

The dapps were initially built native. But currently, they too are moving to the web.

Globally, the web tends toward decentralization, so the popularity of dapps will likely increase.

Ethereum, the most popular open-source platform for blockchain projects, has released a JavaScript library web3.js. This library enables easy development of clients that interact with the Ethereum blockchain in different ways, such as creating smart contracts, writing and reading data from smart contracts, transferring ether between two accounts, and more.  

Web3 library is also available for other programming languages, including Python, Java, PHP, Swift, Scala, etc. Building decentralized applications with user-friendly web interfaces is becoming easier.

The peak hype around blockchain has already passed. But that means it’s high time to start developing powerful solutions that take most advantage of this technology. Maybe, your project will be the next newsmaker?

PWA and AMP - web development trends

Progressive web apps (PWA) and Accelerated mobile pages (AMP)

Google prioritizes web apps that load fast on mobile devices. This is why you should consider implementing PWA or AMP, which are unique technologies that reduce web page load time.

A progressive web app (PWA) is a web page that replicates a native mobile experience. It is fast, can work online or with a poor internet connection, and is relatively low-cost. A PWA supports interactions, allowing users to enjoy a high-end experience without ever realizing that they are still using the browser. E-commerce apps are a common use case for this technology.

An accelerated mobile page (AMP) works for static content only, but they load faster than regular HTML. An AMP omits all fancy elements and displays only the essential information - text, images, etc. This approach works perfectly for blogs and news publishers.

Whether you should adopt PWA or AMP depends on your specific case. However, you should start considering these technologies right now. Along with delivering a high-end experience, you have a chance to dramatically improve your search result rankings.

IoT - new trend in web development

Internet of things

What are the main devices you use to access the internet? Most likely, they are a laptop and a smartphone. However, a much greater number of devices are able to connect to the internet. Yes, we mean the Internet of Things or IoT for short.

Currently, a lot of devices are equipped with a screen. And web apps optimized for data display on smartwatches, refrigerators, smart speakers, etc. will gain popularity.

Mobile-friendliness isn’t a trend anymore, but a must. 2019’s trend is the adaptation of web applications for tiny screens.

Motion UI

Motion design is one of the main web design trends of the coming year. Minimalistic design coupled with sophisticated interactions look good and draw user attention.

Think of page header transitions, nice hovers, animated charts, background animations and modular scrolling. These and many other elements will help you display your unique style and entertain the user, improving behavioral factors and helping your web app rank higher in search results.

Technology stack for web app development

Technology stack for web application development

It is crucial to work with the latest proven technologies to ensure that the developed software matches market requirements and remains up-to-date for several years. And here are the most popular technologies of 2019 and the common stacks:

Front-end technologies

Web development stacks with Angular


We first heard about AngularJS in 2010. 6 years later, in 2016, a complete rewrite of the framework called Angular 2 appeared. The latest stable version at the end of 2018 is Angular 7.

Angular is a Model-View-Controller (MVC) framework. Three separate components enable you to write a well-structured and easy to support code. Two-way data binding is beneficial for simple applications - any changes to the model will be immediately implemented to the view and vice versa. However, if you are working on a complex project, one-way data binding will save you time and resources.

To make most of Angular you will have to use Typescript. You also have to keep in mind that the framework works with regular DOM only, causing some limitations.

MEAN stack is one of the most popular ones out there. It includes:

  • MongoDB - a database

  • Express.js - a web framework

  • Angular - a front-end framework

  • Node.js - backend

The obvious advantage of this stack is that all of its components use JavaScript. As a result, hiring a team of developers (or a full-stack JavaScript developer) shouldn’t be an issue.

Web development stacks with React


In the described stack, Angular is often replaced with React - a Javascript library. The MERN stack is relatively young, but the rising popularity of React has promoted its rapid growth.

React beats Angular due to virtual DOM, which enables faster and easier implementation of changes. However, as React is a library and not a framework, which limits core functionality, developers are forced to work with third-party services.

Also, it is worth mentioning that React uses JSX - a modification of JavaScript that enables seamless component work. So, knowledge of JSX is preferable if you want to make the most of the MERN stack and particularly React.

Web development stacks with Vue.js


Vue.js is a younger JS framework, but it has shown incredible popularity growth over the last few years. This is partially due to the fact that it is a lightweight solution. When compared to a monolith like Angular, it offers basic functionality out-of-the-box. Using third-party services, this functionality is extended. As a result, there is no need to process redundant code, as you must do with Angular.

As you probably guessed, Vue.js is also used together with MongoDB, Express.js, and Node.js as a part of the MEVN stack.

Backend web development stacks

Back-end technologies:

Usually, it is difficult to choose between custom backend development and backend-as-a-service. Both options have their pros and cons, and the choice depends on the needs of the project. We won’t go into detail right now since there is already an article comparing mBaaS and custom backend - check it out to read more on the topic. Here we’ll take a look at the most popular solutions for custom backend.

Web development stacks with Node.js


Node.js is an important component of all of the above-described web development stacks. This is an application runtime environment, which is used to build server-side apps. Work with Node.js requires knowledge of JavaScript. For this reason, it is often used in stacks together with JS frontend frameworks.

Web development stacks with Django


Django is a Python web framework. It can be used with basically any frontend framework (including the ones described above). It is also a good solution for any type of website due to a number of third-party packages available. With Python’s rising popularity, it is worth considering Django for backend of your web app.

Web development stacks with Laravel


PHP is a widely used backend programming language and Laravel is one of its most popular frameworks.

Laravel works excellently with Vue.js. However, Angular and React are also a good match for web app development with Laravel.


It can be hard chase trends since they change so fast. But why not to try?

By following the latest tendencies in web development, you can please your users with a world-class experience, improve your web app ranking, and open new markets for your services!

Over the next few years, voice search will strengthen its positions and force service providers to adapt to the new reality. By approaching it wisely, you can be among the first companies who reach your clients via voice search. Sounds good, right?
