1. 6 WEB DEVELOPMENT TRENDS
TO FOLLOW IN 2021

2. Introduction
Due to the current conditions of the world during the pandemic, the digital innovation has
stepped up its game. Online commerce has been spiking up in 2020, however, every business in
almost all sectors is fighting for a place on the web ecosystem.
Besides the spiking competition, companies also need to stay updated with the dynamic user
demands so that their website does not look outdated.

3. Below are some of the 6 web development trends that are
going to make a mark in 2021.
1. Single-page Apps
It becomes quite a problem when you click on one web page and another one is downloaded from the
server. It is quite time-consuming and leaves a bad impression on the users too. This situation has got
SPA trending.
SPA is one of the recent trends that contribute to avoiding large interaction with the server. It also
offers a high level of data protection as well as enhanced page performance.
Hence, a single-page application can be defined as an app that functions inside a browser and does not
need page reloading while it’s working. These apps are Google Maps, GitHub, Gmail, or Facebook.

4. 2. Progressive Web Apps
These apps has been around in the world of web-development for quite some time. Recently it became
popular when the high-end user-experience associated with them. It allows users to gain access to a
website easily and quickly on handset as it was on the PC. PWA mechanism in the web development
can be seen clearly due to the push provided by mobile technology.
One of the other features of PWA is that it allows access to some of the website features offline also
saving permanent files in a browser cache. Hence, PWAs provide twice the advantage than what it

5. 3. Serverless Architecture
Serverless technologies are gaining popularity to improve site performance by tackling system
overload, simplifying web development, and data loss. This is one of the 6 web development
trends 2021. Cloud computing is one such example that quickly executes simple yet time-
consuming tasks such as object export, installing back-up files, and notification delivery.
Serverless architecture can change your thoughts about web development when it delivers some
decent results at a lower cost.

6. 4. Voice Commerce
We can see the evolution of how we capture information today. These days’ people are obsessed
with AI-driven assistants or chatbots responding to voice instructions. Hence, voice-based
communications have increased because they are convenient and faster than typing problems in
a search bar.
Although, the voice-based interface is not yet accessible currently. This mechanism is still
expected to roll out soon in the society which could make a fine development of your web
development strategy.

7. 5. WebAssembly
Statistics say that 47% of visitors expect a web page to load in 2 seconds , and 40% of
individuals leave a web page if it take more than 3 seconds to load. Aside from the bounce rate,
your conversions are reduced by 7% if you site delays ever 1 second in responding . This means lesser
profits in the business in the long run.
In other words, a good-looking website cannot perform well-enough if it is not high-performing.
However, JavaScript restrictions often make the website slower which affects the user experience. This
is also the reason WebAssembly is gaining popularity. It helps you to assemble the code into bytecode
in any programming script which can run into a browser. This results in quicker load time, a smaller
footprint, and compatibility in cross-browsing. These are the fundamental principles of latest web
development accomplished by WebAssembly.

8. 6. The RAIL Module
This concept was first introduced in 2015, however, it got into news recently for two vital reasons that are
faster loading time of web pages and improved site performance. RAIL stands for:
Response – Each input get an instant response, in 100 milliseconds.
Animation – To complete each structure in 16 milliseconds where dragging and scrolling are the major
components.
Idle – This enhances working by loading only the required components on a page immediately. The
remaining chunks can be loaded in the background afterwards.
Load – It is the primary page features that are loaded initially to entice users and engage them on the
site. These elements are the home screen and navigation bar. While loading the initial screen, the longest
