Ok, so we’re all very well acquainted with our friend, the web browser. It has helped us with so many things in life, answered so many of our questions (well, technically it is Google, but nevertheless), and kept us entertained. It simply became a huge part of our lives. And how?
Through its well-built web applications. Our web browsing experience is influenced a great deal by these two factors, the web application and the web browser. And over the years, we have seen a hell lot of improvements in our browsing. The kind of browsing experience we have now is not something we imagined a few years back. To explain how it has changed, let’s take a quick look at how web apps used to be in the past.
While growing up
Single page apps
Such apps were actually very good for the user as all they needed was the initial loading time. Once that was done, then navigation between the pages would become pretty easy and smooth without refreshing the page and it even supported offline browsing if everything was done right. Even for the developer, such apps were perfect, as there was a clear cut division between client and the server and there was not much sharing of logic required between the two (which are often in different programming languages), which facilitated the smooth workflow.
However, there were a few flaws in this perfect approach for web applications:
Trouble for the spiders
An application that works only on the client side is not capable of serving the web spiders or web crawlers. Web spiders are automated programs or scripts that run to search the web in an automated and systematic manner. The process is called web spidering. A lot of search engines and even sites use this process as a way to provide up-to-date data. What they basically do is request the server for a page and interpret the results. If however the result is a blank page or an undefined page, then it is of no use. Now, as such apps cannot support web spidering, their SEO (Search Engine Optimization) will be poor or not up to the mark by default.
Apart from these, there were several other minor limitations like for example, as there was a clear distinction between the client and server sides, there were chances for duplication of application logic and data, such as formatting of date and the like. Such things were more problematic in case of huge and complex applications.
With all the above-mentioned limitations, there was a need to find a solution that surpassed these issues and yet maintained the efficiency and smoothness of client-side application logic. Thus emerged Isomorphic web applications developed using React.js.
An Isomorphic application is one that can run on both the client side as well as the server side. The code for an isomorphic application can be used or shared by the front end and the back end. A major difference in such applications that make them much better than other applications is the way they process requests. An initial request made by the web browser is processed by the server and all other subsequent requests are processed by the client side.
Now there are a number of benefits associated with Isomorphic applications due to which they are rising in popularity and becoming a huge hit among developers as well as users. Let’s take a look at some of these benefits:
- Speedy– Isomorphic apps are faster to provide HTML content, as the request is not always handled by the server-side. Only the initial ones reach the server whereas subsequent requests are handled by the client-side. This makes browsing faster and more efficient. Moreover, as opposed to common Single Page Applications, where the first request is used majorly for loading the application and then further steps to gather the required data, Isomorphic apps have fast first page processing and even faster further processing.
- Less Code – As the code is shared between the client side and the server side, there is much less code required as against Single Page applications. This makes it a lot easier to develop as well.
Another major factor is the fact that Isomorphic apps can be easily maintained. As there is no need for duplication of application logic between the front end and the back end, it makes handling of even complex applications much easier.
A lot of these benefits make Isomorphic apps very popular among developers, as they all point in one direction – that is, making development easier. They also give the expected results, and that put together with less coding, makes it a favorite among developers.
As for the users, speed and efficiency are the essential drivers. If you have an application that loads fast and gives excellent features, what more do you need?
Just like any application, there happens to be a little flaw with Isomorphic apps as well. It’s just that debugging is a bit of a problem for such apps. There is probably a need to use separate debuggers for the server side and client side of the application. Like for example, for the server side, a node.js debugger would be sufficient while for the client side, maybe the web browser’s debugger would do. It depends on the kind of application as well.
Another possible difficulty could be in managing the settings on both sides. For example, the setting for the server side such as API keys and for the client side like the hostname of resources used such as CouchDB, could vary according to the production environments and it could be quite a task managing them.
Just like any other application, Isomorphic applications have their own share of advantages and disadvantages. In spite of the minor flaws, these apps are definitely increasing in popularity with each passing year because of its ease in development and speed. It is an exciting technology that comes with the option of various isomorphic libraries available, that can be chosen according to the scenario. What do you think about Isomorphic applications?
