8 of the Best Tips to Boost Your AngularJS Application
Share this on:
The digital industry has witnessed a plethora of transformations recently. These changes have disrupted the technological world at various levels, whether through the interaction of artificial intelligence and machine learning or the shift from native app development to cross-platform app development. That’s why market demands and customer expectations are changing dynamically.
If you do not keep up with the pace of the fast-moving tech market, it’s impossible to gain the same audience attention you expected. That’s why your application needs a boost in the context of performance, load time, speed, UI, and so on. In this article, we will discuss the top eight tips through which you can use the AngularJS platform and boost your application to make it at par with customer expectations.
In angular JS, the state represents a particular mechanism that updates the code view based on changes in the concerned model. In a regular program, the state functions gather data from multiple sources and store them in different modules. When similar datasets are stored across an array of modules, it automatically lowers the efficiency and productivity of the application.
As a result, you should implement strategies for managing the states. This way, datasets will be stored at one central location, accessible by all functions and modules in the code base. With the reduction of module numbers, the overall performance and speed of the application will improve.
Ahead of time compilation
Ahead of compilation, it’s a process where the TypeScript code and angular HTML script will be transformed into a better and more understandable programming language. The first stage concerns the creation of a representative code base which is exactly the replica of the original or source code. The AOT collector usually handles it.
In the second phase, the StaticReflector evaluates and determines the type of metadata and information present in the same. In the third phase, binding takes place with the help of the TypeScript compiler and angular template compiler.
Application changes can be simultaneously at the back and front end. If your angular application code does not have any feature or block to detect the changes on time, there will be a discrepancy because end users won’t be able to view the change. It doesn’t mean the change is not implemented at the code level or in the source data.
But to reflect the same in the UI, change detection needs to be done through Angular code. Once you include that change detection block in the code, it will show the results prior to the next iteration of the trigger.
As a result, you will have a complete picture of what consequences users might have to face due to the changes introduced in the back end or front end code.
Immutability and push
When you hire Angular developer, you must confirm they know about all the built-in features of the programming platform, like push and immutability. Sometimes, the reference types represent immutable objects whose value cannot be changed during the entire compilation of the code base.
So the push feature, you will be able to detect a particular value much earlier. As a result, the control flow won’t trace the entire compilation or component tree to find where the change is implemented.
Instead, a push will provide a direction based on the value change it has detected and reduce the complexity of the change detection protocol. You will be able to reduce the changes during compilation through the incorporation of immutable objects. With no object to work on, the change detection strategies can be made simpler, and the application’s overall performance will boost.
As you will include multiple data types or variables within the code for the application, the values will be recalculated every time a specific function is called or triggered. Repeated recalculation of the same values reduces the overall efficiency and performance of the application. Besides, it introduces minute errors that ultimately result in discrepancies in expected values.
Therefore, your goal will be to implement pure pipes within the code base to ensure value recalculation is done at a minimum level. In other words, a recalculation will be done only when the inputs are different for a specific set of variables. The pipe will be called whenever a change reduction protocol is initiated, and the values will be reevaluated based on that changed input.
One of the significant drawbacks of angular applications is freezing threads that handle the components of the user interface. For example, when the graphics need to be resized, a prompt request will be sent to the concerned thread. It will stall the UI actions then and there to complete the request for graphic resizing on an ad hoc basis. This will have a direct impact on user satisfaction and app performance.
Therefore, you can involve web workers within the code base to ensure the main thread is not called during any background activity going for the application. For example, if data needs to be updated in the DB, the web workers will handle the operation instead of sending a prompt ad hoc request to the main thread and forcing it to stall the operations in the UI.
The faster the DOM is, the compact your business logic should be. Any service request and loading function can reduce the speed of DOM and the overall application’s performance. Therefore, you must work on event optimization to refine and compact the business logic.
DOM will work faster and offer the best user experience without any function stalling. The events can be like clicking a button or transmitting data from the front-end server to the back end through API. Reducing the business logic and simplifying it will improve the function of DOM.
The last step you have to take to optimize your application’s performance on the angular platform is the integration of lazy loading. In this process, all the program modules aren’t loaded on the server simultaneously. Instead, only those modules that are marked with high priority are loaded initially. Following this, modules will be loaded according to user actions or the preset priority in the server.
While applications developed on the angular JS platform delineate excellent performance and productivity, code optimization is essential for faster performance and speed. If you or the in-house team cannot deal with angular codes, you must hire angular developer with hands-on experience and the proper skill set.
