Web applications like knockout.js help you to reach out to your audience and customers. And as your customer base increases, your web-application evolves so that you can cater to their varying needs. But the more features you introduce in your application, the more requests and responses need to be handled by your applications. That, coupled with design (CSS) can make your web applications pretty bulky. You must be thinking, “So what! Most of my customers have access to high speed internet”. Well, according to a research conducted by Google, 53 percent of mobile users leave a site if it takes more than 3 seconds to load. That’s about the same time it took you to read the last sentence. So, you have to make sure that your website is light, and monitor it regularly to make sure the feature updates and the patch releases don’t create any loading or performance issues.
Knockout.js, Not Merely a Chip Off the Old Block
- MVVM architecture. The MVVM (Model – View – View Model ) architecture eases the creation of dynamic user interface. It helps to abstract the rendering logic from application logic.
- Declarative binding. Rather than writing code from scratch, Knockout.js allows you to embed data binding expressions in your HTML. This simplifies connecting UI parts to the data model.
- Two-way data binding. Two-way data binding between the data model and UI allows changes in the data model to immediately reflect on the UI, and vice-versa.
Ordinary Monitoring Techniques and Knockout.js Apps
For Knockout.js-based web applications that deal with real-time data binding with the DOM, the performance and the page load time would depend on a variety of user interactions and how the script processes the data provided by the user. For this reason, successful loading of the scripts alone is not a realistic means to monitor performance. There can be instances where the actual load time of a Knockout.js application can take several more seconds to trigger and load the dynamic modules of the DOM. Using ordinary monitoring techniques would give you faulty statistics and you won’t be able to perceive the application’s performance from the perspective of a real end user. This in turn can impact your business and ruin the user experience of your customer base. For such dynamic applications, we should use a bit more sophisticated approach.
Synthetic Monitoring and Knockout.js-based Web Applications
- Using real browsers to simulate user interaction. Rather than using headless browsers for monitoring, use real browsers to simulate user interactions. This approach would account for the time taken by the browser driver to read and render the DOM and load the scripts in the present web page.
There have been great advancements in web application development techniques and strategies over the last decade. In order to ensure that your applications can continue to perform effectively, and meet the demands of your customers, you need an innovative solution that will support monitoring dynamic applications, web pages, and technologies like Knockout.js. Dotcom-Monitor gives you the tools, like the EveryStep Web Recorder, and all the features you need to effortlessly monitor even the most complex web applications and websites.
