How do you hire angle developers
Load test angle applications
Angular is Google's flagship open source web application framework designed for building efficient and sophisticated one-way applications (PSPAs). It is a cross-development platform capable of building modern progressive web apps, mobile and desktop installed applications on Mac, Windows and Linux. Aside from its powerful development ecosystem, Angular offers a clean structure that gives developers the ability to follow design patterns to create, scale, and maintain projects. This allows developers to easily mix and match components, resulting in a smooth application design with decoupled components.
Just writing code to create an angle application can lead to performance issues and slow loading times later. Working with the latest features from the framework and carefully reorganizing the project structure, files, and code are just some of the actions developers take to optimize overall performance. Today's high expectations for lightning-fast load times require developers to pay attention to other areas such as build and deployment time, code improvement techniques, and operational strategies to monitor an app's metrics at runtime to improve application performance.
Problems determining application performance and load times
Because Angular is a modern, script-based framework that offers dynamic web pages, it presents some challenges in monitoring its performance and load time. It is tedious to measure exactly when new content is being rendered on the page, as SPAs do not trigger new navigation in the browser once the webpage has loaded. As a result, HTTP monitoring tools do not provide significant metrics to optimize load times, as Angular does not trigger new browser requests to the server.
Tools to optimize loading times
Angular provides a list of tools and techniques that can help reduce an application's load time and monitor its performance over time, especially after an application has been scaled large enough to handle several heavy calculations. Some of these techniques that can help decrease the initial load time of an application and speed up page navigation are AoT compilation (Ahead-of-Time),the Code division and the preloading of Modules. We'll discuss these techniques in more detail.
There are two main methods of compiling an Angular application: Just-in-Time (JiT), which compiles the application at runtime in the web browser, and Ahead-of-Time (AoT), which, as the name implies, the application does at build time compiled. The AoT compiler compiles the HTML and TypeScript code during the build process before the web browser downloads it.
It helps speed up the rendering process by significantly reducing the time it takes the application to bootstrap. This way, the web browser loads executable code so that it can immediately render the application without waiting for the application to compile. In addition, the precompiled code reduces the number of asynchronous requests to external sources by adding these resources, such as HTML templates and external CSS, within the app. Therefore, the compiled code reduces the separate AJAX requirements for these files. This will make the user experience smoother and faster.
There are two main approaches to code breakdown in an angle app: Code splitting at component level and Code splitting at route level. The main difference between the two approaches is that the code breakdown at the component level lazily loads individual components even without route navigation, while the code breakdown at the route level lazily loads individual routes. In any case, both approaches can be tested taking into account the APP TTI (Time to Interactive). TTI is a great performance indicator to compare against as it measures how much time it takes an application to be responsive. In other words, how long it takes the application to load for the user to interact with it.
Module pre-loading is a technique offered in angular applications that allows modules to be loaded as quickly as possible according to set rules. Modules can all be preinstalled at the same time when a particular event occurs or just a few selected depending on the circumstances. Developers have the opportunity to review how much time it takes to load a module and the value of using a preloading strategy. Pre-loading modules in Angular is similar to deferred loading, except that the application modules are loaded directly after all the busily loaded modules have successfully loaded. In this way, possible latency is discarded when the user navigates to a module that is loaded with a delay and still benefits from a faster initial load of the application, since the first modules are loaded first.
Angular's standard pre-loading strategies are PreloadAllModules and NoPreloading. The first means that all lazy-loadable modules are precharged, while the latter simpere deactivates any preload. When using PreloadAllModules, applications can potentially face a bottleneck if the application has a large number of modules. It is then when considering a custom preloading strategy could be beneficial.
The concept of using a custom preloading strategy might make more sense in a business scenario. For example, preloading the most expensive modules over the less resource efficient modules could be an approach that developers could use. In addition, the time at which modules are pre-installed also plays an important role in reducing loading times.
Load your angle applications with LoadView
LoadView offers an innovative and holistic solution to bypass the limitations of HTTP monitoring tools and to strengthen the tools Angular developers have today to control, monitor and optimize their applications on the client side. LoadView is a cloud-based load testing platform that provides stress test monitoring of websites, web applications and APIs by simulating thousands of simultaneous connections in real time to identify bottlenecks and review overall performance.
After creating an account, developers can test their websites and web applications by creating a device to store the website or application they want to test. The Website option allows angle developers to test the initial load time of their application's landing or login page by configuring a scenario in which thousands of users try to access the page at the same time. On the other hand, by selecting the "Web Application" option, Angle developers can create scripts and test load times for specific use cases of their application.
Example: filling out a form, navigating through application-specific routes, sorting loaded data from the server and, in general, measuring the TTI of your app. LoadView allows users to personalize their test workload type in three different ways, along with an execution plan that specifies how many connections to make over time. In addition, LoadView goes a step further by providing the ability to arrange the geographic distribution of the virtual users connected to the website.
LoadView provides engineers with an efficient and inexpensive way to automate the load testing process compared to traditional methods. No more costly investments and time-consuming processes. Developers and testers don't have to worry about staying within the allocated budget and setting up the infrastructure. They can focus on what they do best and that is taking tests. With true browser-based testing, results and insights are tied directly to user journeys to ensure that your applications can withstand peak load scenarios.
Conclusion: performance of angle weaving applications
Current requirements raise the bar for the performance of modern web apps. Today's DevOps teams need to keep in mind that application response times and application TTI are becoming a critical factor for new applications to have a chance in the marketplace. In most areas, when designing applications, Angular developers need to continuously evaluate and go one step further for reducing load time techniques such as AoT compilation, code splitting and preloading strategies. Continuously test and monitor client-side operations and metrics with LoadView to ensure the best user experience and application performance.
