Some people will learn from others’ mistakes and be cautious. Such are the people who shine out successful in their career. All these principles are applicable to the developers too.
Committing errors in Angular platform
The developers are no exceptional cases for such kind of scenarios. Even they ought to make mistakes in fact in huge number. But to become a successful developer it is important to make less error because it is almost impossible to meet zero error at any cost. So here are some of the common mistakes that are made in the Angular platform. The developers can go through all these points and stay away from these pitfalls. Once you are able to avoid these common mistakes made by Angular developers then you will join the club of flawless certified App developers.
1. Never miss out to unsubscribe
In order to be a part of the best Angular team, you must never come out with silly mistakes. You can never give the excuse of missed or failed to unsubscribe. Cleaning up the subscriptions then and there is an important part of Angular. Whenever you have completed the use of event JavaScript, many libraries are built along with it for that particular purpose.
Leaving it unsubscribed will never clear all those libraries. Failing to unsubscribe at regular intervals can cause memory leaks and does not pave way for effective coding. This will grow out to become a serious problem. So never miss unsubscribing the completed activities.
2. Keep codes organized
This is a significant tip not only for the angular developers but also to the developers of any platform. Always organize the code. This will create a good impression on the developer and also improves the readability. In the future, suppose if any issue rises you will be able to spot it easily and work on it in no time. Having a controller for the view of working with MVC is the most usual one. This is because the controller is the principal layer and it makes compact compartments for every area in the application.
Avoiding this method and adding up new concepts to the single controller and lead to a mess in the future. Whenever a bug arises, you will find it very difficult to clear it. Sometimes you may be pushed into a situation to completely rewrite the code which is a bigger headache.
3. Employ jQuery
When you try to make some changes to the events or alter the existing codes in DOM, here is a tip that you can follow to make the process easier. Utilize jQuery; a customizable library that will make things more comfy for you. But there is a point that you must take care of the main objective of the Angular platform is to develop scalable applications and also to make the app testing, building under the scalable environment. Hence this cannot be used in the construction of the HTML documents. So, if you want to alter only DOM, use jQuery.
4. Never make direct changes to DOM
Sometimes, when will make changes to DOM directly from the controller itself, which is a major mistake. This can cause problems while refreshing the page, validation errors and more similar ones. Hence, never change things directly in DOM. Don’t try to escape and manipulate directly on the go. This will put you under a hard circumstance in the future. You can use Render2 service to make that edit.
5. Avoid acknowledging the same component in multiple modules
A component is the basic building block of an app in Angular. It is important that each component is acknowledged to make it visible and clear for the user. If you are announcing a similar type of component establish a connection between the modules, if not then you have to create shared information Ngmodule.
6. Always give it a check
Some people will fail to take an overview test of the application after its completion. Apart from testing each module, examining the overall app before its launch is also highly necessary. Many people miss out this point and let all their work go in vain after launch.
7. Improper use of Event handlers
Angular is a master when it is designing functionality for the button depending upon user input. But the point is you have to place all the logic in order to function properly.
8. Never declare with anonymous functions
Always use proper naming for the functions. Declaring anonymous functions will reduce readability. Hence be appropriate and standard while naming functions.
9. Assemble Scope binding
Angular has its own scope binding rules. If you commit any mistakes it will prompt the breakdown and aid you in arranging it. To avoid complexities while coding, assemble the scope properly.
10. Utilize Batarang without fail
Batarang is a Google Chrome extension that it used by angular developers to debug apps. Never fail to use this extension; it will give you additional confidence while you launch the app.
