AngularJS has risen to the occasion to be a formidable framework for developing dynamic web applications. When using AngularJS at its full potential, an AngularJS development company can effectively help developers create efficient and scalable applications.
However, even using the best frameworks, some optimizations will help achieve the best results. While using AngularJS to hire AngularJS experts to develop your application, these eight tips will assist in ridding your application of bottlenecks.
1. Optimize Watchers for Better Performance
One of AngularJS’s greatest strengths is its ability to use two-way binding to update the view model. However, every saint has a little devil inside him; the same is the case with power—‘With great power comes great responsibilities.’
Many watchers are not very good since the application begins to slow down, the number of watchers increases, and AngularJS begins to look for changes. The Digest cycle is the core of AngularJS, and avoiding extra watchers can prevent performance issues.
Be very sensitive to your viewers while working with an AngularJS development company. Remove the useless ones and only use them where they are required. In this case, you can also employ one-time binding to reduce the number of checks made continually.
2. Use AngularJS Batching to Your Advantage
Batching is one of the major ways to increase the performance of AngularJS applications. When any model is updated in an application, AngularJS applies all the changes in one digest cycle only. This batching process is efficient, but $timeout or $scope could be incorporated to optimise it. These methods help AngularJS group changes together and apply the changes in batches and not cyclically.
If you apply this approach, you will likely avoid excessive rendering and data-binding cycles that are quite noticeable to the user. If you are a business planning to seek the services of an AngularJS developer, be sure that the developer is well-versed in these techniques for high performance.
3. Lazy Loading to Speed Up Your App
Recently, one important issue of large AngularJS applications is their relatively long time to first byte because of loading all the necessary scripts and modules. To this extent, lazy loading can be applied to ensure that resources that are not essential in loading the home page are not loaded immediately.
This technique ensures that only those components that are required and will be rendered are loaded, thus having a small file size at initialization.
Engaging the services of the best AngularJS web development firm to help you implement lazy loading is possible. As for the components that can be loaded dynamically, some frameworks, such as Angular’s UI router, load only the components required to improve performance.
4. Avoid Excessive DOM Manipulations
Direct DOM manipulation is expensive and has the potential to impact the performance of an AngularJS application negatively. It might appear easier as it is done with jQuery or other libraries, but it is normally against AngularJS architecture.
It’s always better to handle DOM manipulations using directives. This way, your application will be optimised to perform better, resulting in application efficiency. An AngularJS expert will be able to know these best practices to prevent mounting pressure on the DOM and improve responsiveness.
5. Minimize HTTP Requests
This is one everyone should know because reducing the number of requests made can really enhance the performance of your AngularJS application. This must be done regarding the API calls made by your app; your app should only make necessary calls and not fetch data needlessly. Such operations can be easily conducted using tools like $http or $resource.
When working with an AngularJS development company, they will advise you on how to reduce server calls through methods such as caching responses and sending multiple calls at a time instead of one at a time.
6. Use ng-Repeat Efficiently
The ng-repeat is one of the most frequently implemented directives in AngularJS. It is used to create lists based on a given collection of objects. However, whenever these terminologies are used inappropriately, performance is likely to suffer. When there are structures to contain the lists, large lists may cause the production of many DOM elements, which slows down an application.
However, pagination or some sort of scrolling technique should perhaps be applied to prevent an excessive number of items from being shown at one time. An AngularJS development company would be useful for implementing these techniques and increasing the application’s velocity.
7. Leverage Ahead-of-Time (AOT) Compilation
Ahead-of-time (AOT) compilation is an enhanced, optimised process of converting Angular’s templates into concrete JavaScript code before the application starts. This enhances the application’s capacity to start quickly and also lessens the load that a program has to perform during its operation.
If you want to get the most out of AOT, hire AngularJS developers who will work with this technique. They will ensure its responsiveness in the development environment and efficiency in the production environment.
8. Use AngularJS Tools for Debugging and Optimization
AngularJS provides certain tools that can help detect and debug performance concerns. A Chrome plugin known as Batarang offers real-time reports about your application and advises on how to optimize this or that aspect.
It is, therefore, important to work with an AngularJS web development company that understands the use of these tools. The company will make sure that your app is regularly monitored and tweaked for better performance, free from bottlenecks, for the users.
Conclusion
The user experience of an AngularJS application is critical to maximising, hence the need to optimise it. There are numerous ways to optimize the website’s performance, starting with decreasing the number of watchers and ending with lazy loading and, as for HTTP requests, using efficient ones.
If you are unsure where to begin, hiring an AngularJS development company or deciding to build an AngularJS developers team would help you leave your application in expert hands. Hence, if you follow the aforementioned tips, you will develop a very efficient and scalable app that is much more user-friendly.
Businesses planning to advance or improve their apps would enjoy greater benefits from professional AngularJS development services. Whether one hires a company that specialises in AngularJS web development to design a specific app or consults the experts in AngularJS, these practices will help enhance the app’s performance.
