The first impression is everything. And that’s the reason why you need to make sure your applications are free from bugs and errors and bugs.
Developing an application is as important as monitoring it to keep it running healthy for optimal user experience. For this, a superb monitoring strategy is a must for your business to succeed so that you never have to worry about metrics like consistent performance, high availability, and accessibility.
However, many businesses tend to overlook how important frontend monitoring is for their applications. They consider monitoring as a part of their operational efforts, and they usually leave it to an Ops engineer or sysadmin for that matter. It may not be a healthy practice as it overburdens them and might result in loopholes.
Instead, monitoring applications at the frontend is important.
But why frontend?
Software architecture is divided into two main components – frontend and backend.
Frontend includes application components that are executed and parsed on the client-side through mobile or web interface.
Hence, on loading a webpage, components like CSS, HTML,, or images get loaded. Interfaces and applications exposed to end-users are becoming complex and even more powerful these days, which also invites the possibilities of things going wrong.
In case any downtime occurs in an app’s frontend, it could lead to severe losses, including revenue, resources, and, most importantly, customer experience. In addition to complexity, frontend becomes more challenging due to constant updates, changing frameworks, increasing the number of end-users coming through different devices, browsers, locations, and ISPs.
Besides,is also not enough for SaaS and eCommerce businesses dealing with large audiences, and they can’t risk their application’s performance because their business depends on it.
What is all about frontend application monitoring?
Frontend application monitoring is the process of tracking errors, fixing them, and maintaining the health of web applications. It is done to optimize user experience by removing any kind of error that could be harmful to your application. You can catch errors at the initial stage, which would be easy for your developers to tackle. Subsequently, they can work on debugging and improving the code.
Don’t confuse it withbecause it focuses on the ultimate result that users can see while opening your application.
What type of issues do these tools help in fixing?
In the process of doing so, you also need to identify how often these errors pop up along with considering the severity of their impact.
Frameworks such as Angular orare powerful, making the work of developers easier. A frontend application monitoring tool can detect issues based on the functionalities of frameworks, for example, the application state.
Network request failure
Web applications and sites integrate with a variety of external solutions to perform additional functions. This way, they make a huge number of requests to their server where they are being hosted. To this, monitoring tools can record those HTTP requests and the responses initiated by the user to find the errors.
Some monitoring tools can also track app performance metrics, including average page loading time, time-to-first-paint, average server response time, and more.
User experience problems
If a user performs “rage clicks” or clicks some elements quickly for multiple times, the tools can effectively monitor this. Additionally, they can also ensure elements are rendered correctly and detected when a user gets stuck in a certain navigation loop.
Hence, if you build an application, you need to maintain it always so your customers don’t find any issues that could hamper their usability.
Put your customers first, and they will remain loyal to you.
