With the help of new engines and technological advancements in the way the internet works, it is very much possible to host an application on the internet. As long as you have a server that can host the application and a good internet connection that can maintain that host, with sufficient power to withhold stress, anyone can make a web application.
Just because anyone can make a web application does not mean that people will try them. Some features are common between popular & powerful web applications. Here are some of them:
Simple & to-the-point
In the world of programming, hard work does not always translate into better programs. Sometimes you have to think and program smart. Because an application will only grow in size the bigger the code, you should try to keep your application’s code simple and to-the-point. A good example would be to have code that is reusable in multiple areas. A good developer knows to use separate functions & classes instead of keeping all the code in a single method or class.
Less generic APIs
We all understand the blood-rush that we get from finding an API that can let you do something you were always thinking of doing but could not find the logic. However, adding extra APIs or using APIs that are used for multiple purposes will only bloat your web application. This will increase the size of your application and make it harder for not only the server to handle but also for the users to access.
Using less generic APIs can help boost the performance of the program, and also reduce the latency between the user and the program.
Even though all good developers know to keep their applications, especially the ones that are hosted on the internet, up-to-date, not many people know how to do that. A common bad practice is just to update the APIs and update names to make the users think that they are using an updated version of the web application.
A good developer knows to properly code their web application so they can consistently update the code when the need arises. There are always more efficient ways to write a program.
Is tested for security flaws
A proper web application is regularly tested for security flaws. The internet is a free platform, and anyone can connect to anything provided they have the proper protocols. This makes malicious users try and break the application to use for their own malicious purposes and make it harder for other users to use them.
A good web application passes various penetration tests and uses the latest security standards & practices. Hiring a professional tester can also help improve the security of your application.
Catches every exception possible
A good object-oriented programming practice that is usually taught is to try to catch every error possible so that the program itself does not crash. A good programmer knows that the compiler is not perfect, and it can crash every now and together. A good web application does not crash in case anything goes wrong, but tries to safely try another command in case an error occurs.
This improves user retention and helps developers figure out the problem in case a user wants to report the issue.
As long as you focus on the performance, reliability, interface, security, and usability of the program while maintaining the efficiency of the code, your web application will never disappoint you or your users.
