Examples of isomorphic JavaScript apps

Isomorphic JavaScript applications use the same JavaScript code on both the client browser and the web application’s server side. To be considered isomorphic, an application must be able to execute in either a client or server environment and appear the same in both. 

Software engineering is continuously evolving and advancing. The development of JavaScript will continue to grow with isomorphic JavaScript as the next stage. Let’s explore what isomorphic JavaScript applications offer and which companies have adopted this technology. 

Isomorphic JavaScript applications

Isomorphic JavaScript apps combine the best features of traditional web apps and modern single-page apps. Sharing the code between servers gives isomorphic JavaScript apps some distinct benefits. The key features include: 

SEO support

These applications provide SEO support with the help of qualified URLs

Automatic server rendering with no History API support

Through the use of History API, there is no need for a workaround. The web page falls back to server rendering for clients that do not support the History API while navigating.

Distributed rendering and reduced server loads

SPA model subsequent page requests are rendered in a distributed manner for clients that have access to the History API. With this method, server loads are reduced as well.

Easier UI application code updates

With just one JavaScript stack to worry about, only frontend engineers need to update the UI application’s code. Experts only add codes for their specific fields thanks to the clean separation of concerns and duties.

No overlap and lower development costs

Isomorphic JavaScript has a unified rendering lifecycle with a single code base for the user interface. There will be no overlap, you can save money on user interface development, there will be fewer bugs to fix, and you can release new features more quickly.

Reduce page load times

Page load times are reduced by having the server generate the initial page. There is no longer a need to display loading indicators and wait for network requests before the first page appears.

Examples of isomorphic JavaScript applications

Isomorphic JavaScript is widely used by large-scale companies such as Yahoo!, Facebook, Netflix, and Airbnb. Companies in various industries have found the isomorphic JavaScript architecture can be the best fit for various applications. Developing isomorphic JavaScript apps in-house is possible for companies due to the simple app architecture and implementation.

Many different types of companies will decide to set up and operate their own server-side JavaScript execution engine because isomorphic JavaScript applications offer low-cost, simple solutions. Many experts agree there needs to be more features for these types of applications in other programming languages. 

Final word on isomorphic JavaScript apps

Many reputed companies prefer to operate their businesses with isomorphic JavaScript applications because they share the same JavaScript code for both the browser client and the web application server. While isomorphic JavaScript is becoming more widely used, it’s not always the most appropriate option for every website. 

Take evisio for example. Evisio does not use isomorphic JavaScript in our web app. The main framework used is jQuery, but there’s a mixture between this and other small specific JavaScript libraries for certain sections and functionality. For the 2022 version of evisio, no major JS UI framework is used. Tailwind is used as the CSS UI framework.
