Top 5 Technical Issues Large Sites Have with AngularJS

Are you looking forward to creating a large website? If AngularJS is your choice, then you are probably wrong! There can be a number of issues may arise during the development stage which may seem impossible to fix. So, what are these common issues? Today, we will discuss not only the most common AngularJS issues faced by the websites but also guide you with quick solutions to them. Curious to know the details? Keep reading to know more.

Loading JavaScript files 

Usually, large AngularJS projects may require hundreds of JavaScript files. These files are loaded one by one and may even dependant on other JavaScript files. All of this might have a negative effect on the website’s performance.

To manage or clean up the dependencies, it is highly recommended to dynamically load the JavaScript files instead of loading them all. This further allows the files to load in a way user wants, which are actually more efficient. JavaScript files like – RequireJS allow to dynamically implement loading functionality. Now,  the question is what does RequireJS do? Well, it helps to separate the modules by providing them an optimal way to separate modules. This further helps to speed up the applications by utilizing asynchronous script loading.

Slow loading websites is a big no-no! People like using the websites which offer enhanced user experience. The challenges faced to navigate the website can be even more frustrating for the users. But, with the help of dynamic loading, JavaScript files can load without any frustration. So, both the users and the developers can enjoy working on!

Code organization

It is really important to keep the code in the logical manner organized when building a large AngularJS site. It will not help in creating the website but also keep the track and important items in place. You keep on adding more services and controllers as the code base continues to expand. When you add more files, it may get bloated which may further affect the functioning of the site. In such a case, you will find it difficult to accomplish even a simple task of file changesets or specific objects. Not just that, in the large application there can be overlapping of shared common code and modules.

Well, all you need is the organization. If you wish to manage your AngularJS application, then you need to start creating a directory of split up objects and the archetypes in their own files. Now, this helps to eliminate the bulk which is accumulated while grouping. You can also create a directory to divide the modules into submodules and create a directory for shared common code. Doing this will definitely help to streamline the parts of a directory which have overlapped code.

The crux is we cannot ignore having proper organization while creating AngularJS apps. Before you hit any mistake, you can put this effort to put things in order.

Integrating third-party libraries

Third party libraries play an integral role in building large-scale AngularJS apps. The most common issue faced by the third-party libraries is valued returns through AJAX calls or changes in DOM. Angular won’t acknowledge the changes unless you manually start the digest loop. Also, not all third-party libraries are compatible with AngularJS, so you need to keep in mind this as well.

Let’s have a look at the key to integrating third-party library with AngularJS is by using following functions like – $scope.$evalAsync, $timeout, $scope.apply(). Such functions automatically react to the changes from the third-party library.


Debugging code

No matter which web development project you are you are bound to come across some problems which might be difficult to debug. But, there are various tools which can help in the debugging process and simplify the things in a better way. The process then allows you to see specific properties on their current values and various scope elements. The app also allows you to see the objects clearly see the objects that depend on other functions. The graphs help you make better decisions in the future. The tool can help to fix the worst issues in an efficient way and provide you with a smoother and faster running site.

Lazy loading

It is a vital tool for ensuring optimal loading times on the websites and important for large angular AngularJS websites. When the code base grows, more JavaScript files are needed to load the page properly. The lazy loading helps in loading the site by holding off the initializing object. But, you don’t get any official support in Lazy Loading for AngularJS. But, there are many open source projects which can add loading to AngularJS. Try to choose an open source solution which provides you with defined results without any hassle.

In case, you think that lazy loading is not a great option for you, then you can improve the page performance by minification. This process can easily break your site and allow you to change dependencies.

Moving with AngularJS

Although AngularJS is well-known as the superheroic JavaScript MVW Framework, when applied with large sites, it may create problems. Remember, the common Angular issues can be fixed by:

  • Creating a directory for your archetypes
  • Organize your code
  • Split the objects into files
  • Create the directory for sharing common code
  • Load the Java files dynamically
  • Divide the modules into submodules
  • Integrate the third-party libraries by using the right functions

Consider these tips wisely and understand how to deal with the issues.

Well, these are a few technical issues which are commonly faced by people using AngularJS. No doubt AngularJS is a dynamic framework for web apps, but it usually faces problems with large sites. We have mentioned a few technical issues and the solutions for the same.
