Main Features of Angular Development

Simple & Expressive

Angular is a very popular web framework because of its simple and component-based architecture. It perfect for managing heavy web applications that contain a number of components and complex requirements.

Speed & Performance

Angular executes various web techniques like bundling, compression etc. These techniques decrease the load time of web pages. This improves navigation and enhances UX.

Flexible Development

Angular uses component-based architecture. This allows Angular web development professionals to easily build a fully extensible architecture of the web app. The developed components can be reused easily.

Simplified MVC Pattern

MVC is quite popular as it isolates the application logic from the user interface layer and supports a separation of concerns.

Cross Platform

Angular can be used for any platform from web applications, in Electron for desktop apps and in Ionic for mobile apps.

Significant Experience

Being an experienced AngularJS development company, we have rolled out 50 live websites using AngularJS.

Lazy load component with Angular 10

What is Lazy Loading? Lazy loading (also called on-demand loading) is an optimisation technique for the online content, be it a website or a web app. * Instead of loading the entire web page and rendering it to the user in one go as in bulk loading, the concept of lazy loading assists in loading only the required section and delays the remaining, until it is needed by the user. * By default, NgModules are eagerly loaded, which means that as soon as the app loads, so do all the NgModules, whether or not they are immediately necessary. For large apps with lots of routes, consider lazy loading—a design pattern that loads NgModules as needed. Lazy loading helps keep initial bundle sizes smaller, which in turn helps decrease load times. * There are two main steps to setting up a lazy-loaded feature module 1. Create the feature module with the CLI, using the --route flag. 2. Configure the routes. Prerequisites * Node version 12.0 installed on your machine. * Visual Studio Code * Angular CLI [https://cli.angular.io/] version 10.0 * The latest version of Angular (version 10.0) Create a feature module with routing you’ll need a feature module with a component to route to. To make one, enter the following command in the terminal, where customers is the name of the feature module. * The path for loading the customers feature modules is also customers because it is specified with the --route option: ng generate module customers --route customers --module app.module * This creates a customers folder having the new lazy-loadable feature module CustomersModule defined in the customers.module.ts file and the routing module CustomersRoutingModule defined in the customers-routing.module.ts file. * The command automatically declares the CustomersComponent and imports CustomersRoutingModule inside the new feature module. * Because the new module is meant to be lazy-loaded, the command does NOT add a reference to the new feature module in the application's root module file, app.module.ts. * Instead, it adds the declared route, customers to the routes array declared in the module provided as the --module option. ng add @nguniversal/express-engine --clientProject project-example // app-routing.module.ts const routes: Routes = [ { path: 'customers', loadChildren: () => import('./customers/customers.module') .then(m => m.CustomersModule) } ]; Add another feature module Use the same command to create a second lazy-loaded feature module with routing, along with its stub component ng generate module orders --route orders --module app.module * This creates a new folder called orders containing the OrdersModule and OrdersRoutingModule, along with the new OrdersComponent source files. * The orders route, specified with the --route option, is added to the routes array inside the app-routing.module.ts file, using the lazy-loading syntax. // app-routing.module.ts const routes: Routes = [ { path: 'customers', loadChildren: () => import('./customers/customers.module') .then(m => m.CustomersModule) }, { path: 'orders', loadChildren: () => import('./orders/orders.module') .then(m => m.OrdersModule) } ]; Lazy Load Components To explain the process of lazy loading a component, we are going to start with a simplified version of our QuizComponent which simplistically displays the question properties. * We will then extend our component by adding Angular Material components. Last but not least, we react to output events of our lazy-loaded component. * So, for now, let’s lazy load a simplified version of the QuizComponent The first step is to create a container element. For this, we either use a real element like a div or we can use a ng-container , which does not introduce an extra level of HTML. <mat-toolbar> <span>Third Rock Techkno</span> </mat-toolbar> <button class="btn btn-primary" (click)="StartQuiz()"> Start Quiz </button> <ng-container #quizContainer class="quiz-container"></ng-container> * In our component, we then need to get a hold of the container. To do so, we use the @ViewChild annotation and tell it that we want to read the ViewContainerRef. @ViewChild('quizContainer', {read : ViewContainerRef}) quizContainer : ViewContainerRef; * We got the container where we want to add our lazy-loaded component. Next, we need a ComponentFactoryResolver and an Injector which we can both get over dependency injection. > A ComponentFactoryResolver is a simple registry that maps Components to generated ComponentFactory classes which can be used to create instances of components. constructor(private cfr: ComponentFactoryResolver, private injector: Injector, private quizService: QuizService) {} const QuizComponent = await import('./quiz/quiz.component'); const QuizFactoy = this.cfr.resolverComponentFactory(QuizComponent); const instance = this.quizContainer.createComponent(QuizFactoy, null, this.injector); instance.question = this.quizService.getNextQuestion(); Once the start button was clicked, we lazy load our component. If we open the network tab, we can see that the quiz-component.js chunk is lazy loaded. In the running application, the component is shown, and the Question is displayed. Advantages of Lazy loading: * On-demand loading reduces time consumption and memory usage thereby optimising content delivery. As only a fraction of the web page, which is required, is loaded first thus, the time taken is less and the loading of rest of the section is delayed which saves storage. All of this enhances the user’s experience as the requested content is fed in no time. * Unnecessary code execution is avoided. * Optimal usage of time and space resources makes it a cost-effective approach from the point of view of business persons. (website owners) Disadvantages of Lazy loading * Firstly, the extra lines of code, to be added to the existing ones, to implement lazy load makes the code a bit complicated. * Secondly, lazy loading may affect the website’s ranking on search engines sometimes, due to improper indexing of the unloaded content. Conclusion Though there are certain pitfalls of lazy loading yet the big advantages, as optimal utilisation of the two major resources (time & space) and many more make us overlook its disadvantages.

What is MEAN Stack? MEAN Stack Components and Benefits

A tech stack is a set of programming languages and other software tools used to ease the process of software development. Because the IT ecosystem has been working on a large variety of applications for so many years now, they have identified certain combinations of technologies that one can use to ensure efficient development. MEAN stack is one such combination that web developers swear by. In this article, we take a detailed look at what is MEAN stack and how MEAN stack components and benefits facilitate faster, scalable, and profitable web application development. What is the MEAN stack for web application development? MEAN stack is an acronym for a technology stack that uses popular web application development tools and technologies namely MongoDB, Express.js, Angularjs (or Angular), and Node.js. MongoDB MongoDB [https://www.mongodb.com/] is a popular database server that stores data structures in a binary JSON format. It’s categorized as a NoSQL database program that helps in working with large-scale data sets very efficiently. Express.js Express.js [https://expressjs.com/] is a minimal open-source backend web application development framework. Its flexibility makes back end development much easier for developers.. AngularJS or Angular Mainly used to build single-page web applications, AngularJS [https://angularjs.org/] is a robust open-source front end framework based on javascript. Many developers also prefer to use Angular 2+ versions that are simply called Angular. Node.js Node.js [https://nodejs.org/] is an open-source, cross-platform runtime JavaScript environment. It’s a great platform for developing high performing and scalable server-side applications. This Means (pun intended) that if you hire MEAN stack developers [https://www.thirdrocktechkno.com/hire-us/], then you will essentially cut your team into half because you won't have to hire separate backend and frontend developers. Does Your Web Application Need A Front-End Framework? Read More [https://www.thirdrocktechkno.com/blog/does-your-web-application-need-a-front-end-framework/] MEAN stack components and their benefits for web application development Let’s dig deeper into the components of the MEAN stack and see what each brings to the table. 1. MongoDB for database A major benefit of MEAN stack is that it includes the most dynamic NoSQL database in the form of MongoDB. Why choose MongoDB over MySQL Although MySQL is the first choice for most developers, here’s why MEAN developers prefer MongoDB to MySQL: MongoDB is more flexible in terms of schema design MySQL would not allow you to make any changes without changing your schema design. This considerably slows down the development and deployment process and binds you in terms of flexibility. Thus, flexibility in schema design tilts the scales in favor of MongoDB. It works perfectly fine even if you drop a few documents which do not have any relation with each other in MongoDB. This is the power of non-relational databases. MongoDB facilitates more speed and better performance MySQL works well with structured data sets that are small in size. However, if you have a large unstructured data set, then using MySQL would feel like trying to douse a fire using a garden hose. Too little too late. The magic of MongoDB is in its ability to handle large unstructured data sets with lightning-fast speeds. Thus, MongoDB is an essential part of MEAN stack components and its benefits are unmatched for an efficient database. How To Choose A Technology Stack For Web Application Development Read More [https://www.thirdrocktechkno.com/blog/how-to-choose-a-technology-stack-for-web-application-development/] 2. Express.js for Javascript applications development The backend of any web application is where the real magic happens. If you have a complicated backend, then your application will be equally complicated. The use of Express.js for handling the backend is the major highlight of MEAN stack components and benefits. Express.js is a flexible and efficient Node.js framework. If you are looking for a perfect balance between ease-of-use and a full feature set, then Express.js is your answer. Express.js ensures a smooth data transfer to the end-user by managing the interactions between the frontend and the database. Here are the main features and benefits of using Express.js for web app development. * It is a minimalist framework designed to handle the processes of your application without cluttering it. * Express.js is an excellent error handler which provides easy templates to speed up your development. * CommonJS in Express.js saves time by ensuring that you do not have to redefine a variable within a shared namespace. * It allows you to scale your application quickly as you can easily add nodes and extra resources per your requirements. * Powered by Google’s V8 engine, Express.js facilitates better performance without any lags or errors. * Express.js supports the caching feature. Hence, you don’t need to re-execute the codes often which in turn reduces the loading time of your web pages. 3. AngularJS for front end development 2010 was the year when AngularJS was launched. Since then, it has remained one of the most popular front-end JavaScript frameworks. After the launch of an enhanced version, Angular 2+ (simply called Angular) has become a fan favorite too. So what does Angular bring to the table as a front-end framework? Let’s see how Angular plays its role in MEAN stack components and benefits: * The modular structure of Angular allows you to segregate the entire application into exclusive features. Thus, you can easily identify the reusable chunks of code and save tons of development time. * Angular facilitates lazy loading. This enables the browser to instantly show the data users have requested, without unnecessarily downloading the entire data first. * The component-based architecture of angular ensures that new developers don't find it hard to understand the application code. * CLI(command line interface) of Angular simplifies the app development process and enhances the code quality. * The dependency injection function in Angular boosts the application performance and speeds up the development process. * The Ivy renderer minimizes bundle size, making large scale apps much lighter. * Typescript allows the developers to spot and correct errors on the go. * Using the declarative view function, developers can save time as it automatically loads the components as per the layout. MEAN vs MERN: Should you choose Angular over React? MERN stack is another popular technology stack for web development. The only difference between MERN and MEAN stack is that the former uses Reactjs while the latter uses Angular for web development. Here are the key differences between Angular and Reactjs for web application development. * Angular is a complete front-end framework while Reactjs is a library that needs third party support. * While Reactjs allows you more liberty to choose additional features, Angular has a limited set of optional features. * The learning curve is steeper for Angular as compared to Reactjs. * Building an application is faster with MERN stack but MEAN makes your web app scalable and high performant. So the choice between Angular and Reactjs is rather dynamic. It depends upon your project and the kind of developers that you have. Moreover, Reactjs is best for web applications that are dynamic in nature and require a quick response to data changes. Angular, with its advanced features, is the ideal framework for enterprise-level applications. Differences Between Angular And React For Web Development Read More [https://www.thirdrocktechkno.com/blog/differences-between-angular-and-react-for-web-development/] 4. Node.js for back end development MEAN stack components and their benefits are ideal for efficient cloud-based applications with scalability needs. This is because it has Node.js as its back-end framework. Node.js is an open-source JavaScript framework that uses asynchronous events to process multiple connections simultaneously. This feature of Node.js helps the framework to use a single thread architecture, providing a smooth user experience across multiple connections. In addition to that, Node.js provides a host of other benefits. * It drastically shortens the time to market cycle. * With Node.js, you get immediate feedback from the production environment making deployment simple. * Node.js allows better scalability. * It eliminates the necessity to switch between backend and frontend. * Node.js is a well tested and mature tool with a huge developer support community. * MVP development is easy and quick with Node.js. * It doesn’t have a steep learning curve and hence anyone knowing JavaScript and object-oriented programming basics can master Node.js. Most Prominent Node.js Development Trends in 2020 Read More [https://www.thirdrocktechkno.com/blog/most-prominent-node-js-development-trends-in-2020/] Advantages of using MEAN stack for web application development Consolidating the features of each of its components, MEAN is a holistic stack for web development. MEAN stack components and their benefits bring the following advantages for web app development: Development with MEAN stack is economical Mean stack developers can complete the project all by themselves and you do not need to hire separate developers for frontend and backend and database management. This reduces the headcount, in turn reducing the cost of building a web app. MEAN stack is a combination of open source technologies, which helps in keeping the costs to a minimum. JavaScript facilitates a holistic and smooth development process Mean stack uses JavaScript throughout the code. As the client and server-side language are the same in the MEAN stack, there are fewer hiccups in the process. Angular allows the developers to reuse the code making the process smoother. Active community for long term support JavaScript is one of the most common programming languages. Hence, it has an active developer community which provides solutions to day to day problems faced by JavaScript developers. If you are stuck up, then you can count on the JavaScript community to provide you quick a solution. MEAN stack provides flexibility to switch between codes MEAN stack allows the developers a high level of flexibility as it is easy to switch between codes. For instance, if you started coding in Node.js but found in the due course of time that AngularJS would have been a better option, then you can easily switch between the two languages without adding any complications to your project. Easy testing MEAN stack and its components have the benefit of allowing you to test an application on the cloud platform easily. It also allows you to add that extra bit of information as MongoDB is specifically designed for this purpose, providing full cluster support and automatic replication in the cloud. MEAN stack helps speed up the development process Due to the virtue of its non-blocking architecture, the MEAN stack is a speedy framework. Angular accords reusability of metastability and easy maintenance to MEAN stack. The Bottom Line MEAN stack components and its benefits have gained a lot of popularity in recent years. Like any other tech stack, MEAN isn’t ideal for every kind of app out there. However, considering the use of Angular, it’s perfect for building enterprise-scale apps and single-page apps. Moreover, the flexibility to switch between client-side and server-side codes makes it an easy choice for cloud-based native apps too.

Server Side Rendering with Angular 10

Why Do We Need Server-side Rendering? Angular applications are client-side applications that execute on the browser - which means they are rendered on the client, not on the server. You can add server-side rendering to your app using Angular Universal. There are two main reasons to create a server-side version of your application: * Performance: Rendering Angular on the server-side improves the performance of your application, particularly on mobile and low-powered devices since the browser will not need extra time to render content which reduces the time for the First-contentful Paint * SEO: Server rendering allows search engine crawlers to easily crawl your web app which helps with Search Engine Optimization What is Angular Universal? Angular Universal is a technology that takes care of rendering Angular applications on the server. It runs on the server-side and generates pages that are sent to the client browser which allows the application to render more quickly, giving users a chance to view the application layout before it becomes fully interactive. Getting started with Angular Universal Step 1 - Add @nguniversal From your app directory open a terminal and run the following command: ng add @nguniversal/express-engine --clientProject YourProjectName This command will install the required packages and it will add and update all required files to implement server-side rendering in angular application. CREATE src/main.server.ts CREATE src/app/app.server.module.ts CREATE src/tsconfig.server.json CREATE server.ts UPDATE package.json UPDATE angular.json UPDATE src/main.ts UPDATE src/app/app.module.ts UPDATE tsconfig.json Step 2 - Building and Serving the App run the following commands: npm run build:ssr npm run serve:ssr This will serve the angular application with server-side rendered pages on http://localhost:4000 address npm run build:ssr : This command compiles and create dist folder and in that folder there were  2 folders /browser and /server, normal build and server build. dist -browser -server Folder Structurenpm run serve:ssr : This command serve /server folder only, but when any request is made from browser, it serve template and other static files from /browser folder. Things to remember: Since a Universal application runs on the server and not in a browser, there are a few things you need to watch out for in your application code: * Check your use of browser-specific objects, such as window, document, or location. These don’t exist on the server. * By importing the functions isPlatformBrowser and isPlatformServerfrom @angular/common, injecting the PLATFORM_ID token into your component, and running the imported functions to see whether you’re on the server or the browser. Example: import { OnInit, PLATFORM_ID, Inject } from '@angular/core'; import { isPlatformServer } from '@angular/common'; export class SomeClass implements OnInit { constructor(@Inject(PLATFORM_ID) private platformId: Object) { } ngOnInit() { if (isPlatformServer(this.platformId)) { // do server side stuff } } } "window is not defined" And "Document is not defined" One of the most common issues when using Angular Universal is the lack of browser global variables in the server environment. Solution for "window is not defined": Create service file (Example:  global-object.service.ts) For Example: import { Injectable, Inject } from '@angular/core'; import { DOCUMENT } from '@angular/common'; @Injectable() export class GlobalObjectService { constructor(@Inject(DOCUMENT) private doc: Document) {} getWindow(): Window | null { return this.doc.defaultView; } getLocation(): Location { return this.doc.location; } createElement(tag: string): HTMLElement { return this.doc.createElement(tag); } } After creating service file use this file wherever window object is used import { GlobalObjectService } from '@shared/services'; import { isPlatformBrowser } from '@angular/common'; export class AppComponent implements OnInit { constructor( windowRef: GlobalObjectService, @Inject(PLATFORM_ID) private platformId: object, ) { this.windowRef = windowRef.getWindow(); } ngOnInit() { if (isPlatformBrowser(this.platformId)) { this.windowRef.scrollTo(0, 0); } } } This code is solve "Window is not defined" error Solution for "Document is not defined": The above solution is also use for "document is not defined" error but if you still facing this error you can also use this code in server.ts file const domino = require('domino'); const fs = require('fs'); const path = require('path'); const templateA = fs .readFileSync(path.join('dist/NinsUserFrontend/browser', 'index.html')) .toString(); const win = domino.createWindow(templateA); win.Object = Object; win.Math = Math; global['window'] = win; global['document'] = win.document; global['branch'] = null; global['object'] = win.object; Conclusion: We've seen that Server-side rendering works by rendering a part of your client-side app on the server instead of the client. This can help increase performance and allow all search engine crawlers and social media networks to easily crawl your application for SEO purposes. We also used the @nguniversal/express-engine to quickly create a Universal version of our Angular application and prepare our app for server-side rendering.
