Top Mistakes Angular Developers Must Avoid While Building Apps
by Tech Geekk writerAs lucrative as development is, the fact remains that it can often prove to be tricky. It holds for any programming language developers may be working with. So while it is a vast topic, today, we'll be looking closely at one language in particular -- Angular -- and go through the common mistakes many developers make while working with it.
Also, before we get started with this, we must clarify that these mistakes are not a death knell for the project you may be working on. They will most likely affect the quality or take a toll on the product's performance. However, look at the brighter side: here you have a list of the most common mistakes Angular developers are known to make. You can use this list to make sure that you don't go down the same path as well!
Anyway, back to business: the top mistakes Angular developers make and how you can avoid them.
- Watch out for the watchers: Any developer who has worked with Angular knows that it generates a watcher for each binding. Furthermore, the comparison and assessment of previous bindings are done at every single digest phase. Long story short, this can result in far too many watchers. Don't get us wrong -- handful watchers are no problem, but they can wreak havoc when you have hundreds and thousands of watchers in your code. Consequently, it impact's the app's performance in the browser. The maximum limit is 2,000 watchers, according to the Angular global community. So, make sure that you keep an eye on the number of watchers from the get-go.
- Compartmentalize code: When you work with Angular, it is crucial to sectionalize the code. Allow us to explain: While working with MVC, the idea is that the developer has the Controller for a View. The controller is the logical layer, and it is essential that developers make compartments for every aspect of the app within this layer. What developers usually end up doing is putting the excessive concept into just one controller. So, in case you need to differentiate the layer for the application to be logical, be sure to make compact, organized units for the logic layer.
- Don't depend on jQuery: Angular offers a vast number of features that all developers working with this language should know about. It will help them avoid using jQuery in the development process. Like, even if they require DOM manipulations, they don't have to use jQuery necessarily.
- Testing is vital: It might seem almost redundant to say this, but you'd be surprised to learn how many developers fail to test their app before releasing it. It is because they are unaware of the potential bugs different environments can result in.
Don't worry; you don't need an environment for each operating system; instead, developers can leverage leading cross-browser testing tools to test the app.
So, when you go looking for an expert for Angular development, keep the above discussion in mind to make sure that your product doesn't suffer at the hands of these blunders.
