Angular Best Practices to Build WebApplications

Angular, a completely rewritten version of the AngularJS framework created and maintained by Google, is specifically intended for developing dynamic programming structures. Modules, components, metadata, templates, data binding, services, directives, and dependency injection are the fundamental building blocks of Angular.

It frequently develops a wide range of additional internal platforms for developing SPAs with cutting-edge tools including HTML, CSS, and Typescript. Furthermore, as is well known, TypeScript development services are a superscript of the JavaScript framework, which is specifically employed in the creation of Angular apps. We can develop UI applications that are more robust and compatible by utilising Angular technology.

Due to these features, Angular will continue to rank among the most widely used front-end frameworks in 2023. To make it simple, we have created an article that outlines the angular js best practices that every developer should adopt to create reliable online applications.

Angular Best Practices ThatYou Need To Follow

The greatest framework for creating strong, feature-rich web applications for your business requirements is Angular. Read the post on what is Angular to learn more about the Angular framework. Let's now examine some of the top Angular best practices that you must adhere to in 2023 for developing powerful online applications.

● Angular CLI

● Use ES6 Functionality

● Maintaining Proper Folder Structure

● Make a Habit of Using Lazy Loading

● Angular Coding Practices

● Using “trackBy” Along With ‘ngFor’

● Using Interfaces

● Single Responsibility Principle

● Make a Habit of Using Safe Navigation Operator (?)

● Prevent Memory Leaks in Angular Observable

● Using index.ts

● Build Reusable Components

● Using Immutability

● Implementing Lazy Loading

1. Angular CLI

A comprehensive and powerful tool, Angular CLI (Angular Command Line Interface) aids in the startup, development, maintenance, testing, and even debugging of Angular apps. The primary purpose of the Angular command line interface tool is to streamline scheduling and the entire strategy.

So, when using CLI for your in-house Angular applications, you must know the essential functions of Angular CLI. So, if you want to install CLI using NPM packages, you must use npm install -g @angular/cli.

Angular CLI makes it simple to start the app development process and is regarded as one of the simplest ways to comprehend business logic, regardless of whether another developer has worked on it. It will eventually lower many costs and provide engineers with more time.

Now, let us explore some of the commands that help you deal with Angular CLI commands.

● ng new: To create a new Angular app from scratch and can start a fully functional application right out of the box.

● ng create: To use test shells for creating components, routes, services, and pipes with a single command.

● ng serve: It is primarily used for an application that is developed locally and needs to be tested in the developing phase.

● ng test: It is used to run end-to-end or local unit testing of the most common command.

● ng lint: It plays a vital role in creating a code shine using its own lint rules.

● ng add @angular/pwa: If you want to set up an Angular service worker.

2. Use ES6 Functionality

ES6 stands for ECMAScript 6, and it gives you the ability to work with new syntax and angular features to create code that is more up-to-date and comprehensible. New features and functions are continually added to ES6. You can frequently programme JavaScript more easily thanks to ES6 capabilities like Let and Const, Arrow Functions, and Object Literals string interpolation.

3. Maintaining Proper Folder Structure

Maintaining file and folder structures that make your work easier is one of the most popular Angular-recommended practices. Let's examine the naming conventions for files and classes as well as the structure of the folder hierarchy in an Angular project.

● File Naming

● Class Naming

● Folder Structure

4. Make a Habit of Using Lazy Loading

Different modules, such as documents, JS, CSS, videos, photos, etc., are often loaded slowly. It is exclusively in charge of accelerating the application's load time, and it typically does so by splitting the load into numerous packets and loading them as needed.

Lazy loading can be useful to you while your large application loads rather than employing other related routines to accomplish a lazy load of the feature modules. When something is used, lazy load processing will begin. Instead of loading the component in the AppRoutingModule routes configuration, the Angular developers working for the top AngularJS development company use the lazy-loading function to loadChildren.

5. Angular Coding Practices

You must adhere to Angular code standards, which is one of the most popular Angular best practises.

It is a powerful method for creating mobile and online applications. To create Angular applications that offer the best user experience, you can adhere to specific coding standards.

Full-stack developers find it difficult to address urgent problems and fix defects, especially when working with intricate code structures.

Let’s explore some angular code standards, as a part of Angular guidelines, need to follow to make web application development comply with the standard Angular style guide.

● Per file, the code must not exceed 400 lines limit

● Per function, the code must not exceed 75 lines

● Utilise custom prefixes to prevent element name collisions with components in other apps and with native HTML elements.

● If the values of the variables are intact, declare it with const

● Names of properties and methods should be in lower camelcase

● Always leave one empty line between imports and modules such as third-party and application imports and third-party module and custom module

● We shouldn’t name our interfaces with the starting capital I letter as we do in some programming languages.
