Various dynamic structures of programming such as mobile apps, web applications, SPAs, etc. require powerful frameworks for incorporating smart and intelligent features. Angular is one such framework that is capable of getting integrated with any other framework based on JavaScript. A wide variety of tools facilitated by Angular can help you create a website or application that will have a great competitive advantage provided you use best Angular practices during your development process. Expert developers at the leading Web Development Company in the expansive research and experimentation process, regarding the Angular practices.
Coping up with frequent updates and alterations can be one of the biggest challenges with Angular. Angular 2 was released by Google in May 2021. Keeping in mind all the functionalities of Angular 2, we have come up with the most interesting best practices ideas that can help you get the best out of this functional framework.
Angular Best Practices Ideas
1. Angular CLI
Angular is a framework that has a unique line of commands. For Angular ideal practices, you must install that command line and utilize it as much as you can. It is quite a time-saving thing to utilize predefined commands in Angular rather than typing everything manually. For instance, creating a fresh Angular project will need you to invest around one or two hours if you do it manually. But if you make use of commands, the process will be pretty much less time-consuming in the way shown in the below example:
ng new abc(nameOfTheApplication)
After this, this application can immediately be run.
ng serve
Various Command-line interface tools and any type of file can be generated for Angular. It can be a service, component, or component.
2. Braking large Components into Smaller Ones
Some components are bigger, and sometimes it may become hectic for you to manage such components and maintain the crispness and cleanliness of the project at the same time. Hence, it is a good idea to break Angular’s large components into parts that are of different manageable sizes. By doing this, you may experience increased efficiency of your Angular app which is further beneficial for your overall project success.
3. One File One Function Principle
Another important practice in Angular is to make sure that you do not create multiple instances for any directive, service, or component inside a single file. One file must have the responsibility of only a single specific function. By doing this, you will be making your Angular code easily manageable, clean, readable, and easy to maintain.
4. Clear and Clean Folder Structure
Having a good folder structure is another good practice with Angular. Keeping it clear and recognizable is always recommended. Make sure you create folders to group components and elements of related features together; this will ultimately help you locate the files easily wherever required. It also helps enhance the code dependencies’ visibility.
5. Reuse Components
While developing Angular applications or web pages, the creation of large components requiring similar logic is quite easy. But it is much more beneficial that you create reusable and smaller components keeping in mind their smart and dumb versions. The major benefit of doing this is that you can save a lot of time due to their reusability along with their easy maintenance.
6. Utilize Interfaces
There is a great possibility that you will work on some API data which generally possess a predefined JSON format. Ideally, you type it with interfaces rather than using any of those. The interface lets you also specify whether a property is mandatory or not.
7. Utilize Navigation Operator that is Safe
If you are not using a secure navigation operator, there is a great possibility that you will get an error. By using a safe navigation operator (a question mark in this case) you can eliminate any critical error.
8. Creation of index.ts Files
Creating a comparatively bigger application will involve the import and export of a large number of elements into the application. In the case of a larger number of exports, a single file can be used to accumulate all the exports. A simple index.ts file can do this for you.
9. Avoid Type ‘any’
For matching anything, Angular generally allows you to make use of the type ‘any’. This can result in many errors if you are working on a complicated project. The errors may include undefined values, type mismatch, property name typo, etc. By avoiding this you can eliminate bugs and save more time.
10. Avoid Scroll Event
Scroll events are triggered as soon as a user starts scrolling a website. A large number of functions start executing with this event. By avoiding this event, we can help increase the performance of the application.
11. Documentation is Important
Documentation is an important part of any of your Angular projects. Make sure you write down important notes alongside the code so that various developers involved in the project may understand the logic and intent of your code.
Hope these ideas will help you with your Angular projects by following the best practices and taking your Angular application to the next higher level. You can contact a well-established Web Design Company to consult the professionals, and acquire further details.
