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

As an established AngularJS web development company, we have rolled out 50 live web applications using AngularJS.

Angular Routing

Routing in a single-page application gives a feel to the user that the user will be just seeing HTML upgradation and new data rendering, this is a faster approach for avoiding the timespan of loading a whole new page from the server. Here only the view will be updated and for updating the view from one to another Angular Routing is used. The Router enables navigation by interpreting a browser URL as an instruction to change the view. Angular Router * Angular Router is a powerful Javascript router built and maintained by the Angular Core team and it can be installed by installing  @angular/router package. * It provides a complete routing library with the possibility to have multiple router outlets, different path-matching strategies, easy access to route parameters, and route guards to protect components from unauthorized access. Router Outlet * The router-outlet is a directive available from the router Library which helps to change components based on the URL * A single application can contain multiple router outlets * For adding router outlets you need to add the following code in the HTML file Routes and Paths * Routes are comprised of a path and a component attributes * The path refers to the part of the URL that determines a unique view that should be displayed, and the component refers to the Angular component that needs to be associated with a path. * Based on the route definition provided router will navigate the user to a specific view * Each route maps a URL path to a component * The path can be empty which is a default path and is generally used at the start of the application Wildcard routes * Wildcard routes are defined by string (**) * This route will be executed if the requested URL is not defined in the routes * These routes are generally used to define Not Found routes * For example, Routes matching strategies * Each route can have different matching strategies. Default strategies would be just matching routes in the browser URL which is just matching the route path’s prefix. * For example, the default path definition can also be written as, * Here the patchMath attribute specifies the matching strategy. In this case, it’s the prefix that is the default. * Another matching strategy is “full”. When it's specified for a route the router will check if the path is exactly equal to the path of the current browser’s URL: Route Params * For passing data between multiple components angular routes will help * Angular Router allows you to access parameters in different ways: * ActivatedRoute * ParamMap * For passing route params you can use colon syntax, For example: Route Guards * Developers can set the route guards to set a logic whenever a route is accessed. * This logic will define whether the user should be able to access the component or not * For example, If the developer wants to check if the user is logged in or not at that time route guard will not allow non logged in user to access private pages * You can add a route guard by implementing the CanActivate interface available from the @angular/router package and extending the canActivate() method which holds the logic to allow or deny access to the route. * Route guard example, * You can then protect a route with the guard using the canActivate attribute: Navigation using HTML * For creating navigation links, the angular router provides routerLink directives. * This directive takes the path associated with the component to navigate to. For example: Using multiple router outlets * Using an angular router we can add multiple router outlets in a single application * A component has one associated primary route and can have auxiliary routes. * Auxiliary routes enable developers to navigate multiple routes at the same time. * All outlets should have a name instead of the primary outlet. * For example, * Then you can specify the outlet in the routing file where you want your component to be rendered Conclusion This tutorial demonstrated how to use the Angular Router to add routing and navigation to our application. We covered concepts like router-oulet, routes, and paths. Blog Ref:

Managing state in Angular, Which one is better: RxJS or NgRx Store

While building a large-scale application, state management helps to modularize applications, making code more feasible and readable. There are multiple libraries in angular for state management like NgRx, Akita, or NgXs. Still, RxJs provides simple state management techniques using RxJs. RxJs Observables * Observables are the core of RxJs which helps in implementing state management in simpler Angular Applications * Using observables it is easy to inform components about the updated states * Components can easily subscribe to the last state that the observable holds * Observables emit a new value each time it is subscribed by the component Let's have a look at the RxJS-based state management techniques, which are as below * Subject * BehaviorSubject Subject * Here first we are assigning value “1” to mySubject using That will call both the subscribers and print consoles a and b. * Then we updated the value to be emitted to “2” using That will again call both the subscribers and print consoles a and b. * Then we emitted one more value “3” to all the subscribers using the same Which will again call all three subscribers and print consoles a, b and c BehaviorSubject * In the above example, we have a behaviorSubject with two subscribers and we are assigning three values to them. * Irrespective of the time when they are subscribed each subscriber gets the latest value of the behaviorSubject. * The output will look like this Here is the basic difference between the both of them. BehaviorSubject vs Subject The major difference between BehaviorSubject and Subject is that the former holds an initial value that can be subscribed to immediately whereas the latter does not. Let's have a look at the programmatic difference between both of them What is NgRx Store? It is basically Redux inspired state management technique for angular applications. Have a look at the below diagram which explains the detailed flow. State Management using NgRx store is basically a combination of the below techniques: * Store: The application’s latest state is maintained in the store and it is immutable * Selectors: Selectors help the components to get updates from the store * Reducers: Reducers are responsible for handling the transition from one state to another * Actions: Actions update the state of the store with the help of reducers * Effects:  Effects are the results of Actions. They are helpful to listen to particular action types and execute as soon as the action happens Use NgRx store in Angular Creating a store: * As the first step, you need to create a model of the book which will look like below. The file can be named book.model.ts * Then we will create one excel file to define the actions of the store. The file can be named book.actions.ts. The actions files will be under the Actions folder. * In the above example, we have defined one enum for the action constant. * Then we implemented the AddBookAction method using the NgRx Action class, which accepts two parameters: a type and an optional payload. * Now its time to create a reducer that will help with state transitions, so inside the reducers folder we can create series.reducer.ts file: * In the above reducer, we have created an initial state for the Book interface and a reducer function named BookReducer Which accepts a state and an action as input parameters. * If the action type is ADD_ITEM, it will return the state and the payload. Otherwise, it will only return the state. * For the last step, we need to create one model which will help to store the state of the whole application in a single space * That main state model will be named state.model.ts Registering store: The next step will be registering the store in the module file which will be the main app.module.ts file Using NgRx Store: After registration, you will be able to access the store in the app component as below * The above code shows the app.component.ts file of our example. * There, we have set book$ to a type of observable and subscribed to the store to get the books. * The addBook() function is responsible for dispatching new books to the store. Conclusion This article concludes that state management techniques should be decided based on the requirements and the scale of the application. For larger and more complex applications NgRx store is more suitable because it helps to provide a single store for global applications wide state whereas RxJS observables and services are for smaller tasks and applications managing local level states.

How to read local JSON files in Angular

In this tutorial, I am going to create a sample application to show how to use local JSON files in an Angular application. There are different ways to read local JSON files in Angular. we’ll see different ways to read local JSON files in Angular for example. It turns out there are at least a couple of ways to do it. I will mention the most common ones: 1. Using the import statement 2. Using Angular HttpClient Step 1: Create a new Angular Project Create an angular project using the CLI command: ng new json-read-example Step 2: Create a new JSON file under the assets folder We’ll create dummy JSON data files that will be containing a list of students. [ { "id": 1, "name": "Luca", "email": "", "gender": "male" }, { "id": 2, "name": "Lilly", "email": "", "gender": "female" }, { "id": 3, "name": "Anna", "email": "", "gender": "female" }, { "id": 4, "name": "John", "email": "", "gender": "male" }, { "id": 5, "name": "Mary", "email": "", "gender": "female" } ] Step 3: Methods for Reading Local JSON Files 1. Using the import statement One way to read a JSON file from the assets folder in Angular is to use the import statement in your component. import { Component, OnInit } from '@angular/core'; import * as studentData from '../assets/students.json'; @Component({ selector: 'app-root', templateUrl: './app.component.html', styleUrls: ['./app.component.scss'] }) export class AppComponent implements OnInit { title = 'json-read-example'; data: any = studentData; ngOnInit() { console.log('Data',; } } You need to add "resolveJsonModule": true in the compilerOptions of your tsconfig.json the file that is at the root of your Angular application. { "compileOnSave": false, "compilerOptions": { "baseUrl": "./", "resolveJsonModule": true }, "angularCompilerOptions": { } } 2. Using Angular HttpClient A second way to read a JSON file from the assets folder in Angular is to use the HttpClient Now let’s see an example of it. Import HttpClientModule in our root module. (app.module.ts) like below: import { NgModule } from '@angular/core'; import { BrowserModule } from '@angular/platform-browser'; import { HttpClientModule } from '@angular/common/http'; import { AppRoutingModule } from './app-routing.module'; import { AppComponent } from './app.component'; @NgModule({ declarations: [ AppComponent ], imports: [ BrowserModule, AppRoutingModule, HttpClientModule ], providers: [], bootstrap: [AppComponent] }) export class AppModule { } In this case, we simply subscribe to the Observable generated by Angular HttpClient and log the data in the console The HTTP protocol is utilized by the majority of front-end apps to connect with the server. When working with an application that uses Angular, we may make use of the HttpClient service available from the @angular/common/http package to read JSON files from an Angular application. import { Component, OnInit } from '@angular/core'; import { HttpClient } from '@angular/common/http'; @Component({ selector: 'app-root', templateUrl: './app.component.html', styleUrls: ['./app.component.scss'] }) export class AppComponent implements OnInit { title = 'json-read-example'; studentData:any; url: string = '/assets/students.json'; constructor(private http: HttpClient) {} ngOnInit() { this.http.get(this.url).subscribe(res => { this.studentData = res; }); } } Display table view using the below file <p>Read Local JSON file student data using typescript HttpClient</p> <table id="student"> <tr> <th>Name</th> <th>Email</th> </tr> <tr *ngFor="let student of studentData"> <td>{{}}</td> <td>{{}}</td> </tr> </table> Some other way to read JSON file 1. use the fetch API 2. use angular jsonPipe Use the fetch API We use Javascript fetch API to retrieve our static JSON file. Which is available in all browsers. This is an example Angular 14 component that uses the Fetch API to read a JSON file: import { Component, OnInit } from '@angular/core'; @Component({ selector: 'app-root', templateUrl: './app.component.html', styleUrls: ['./app.component.scss'] }) export class AppComponent implements OnInit { title = 'json-read-example'; studentData:any; url: string = '/assets/students.json'; constructor() {} ngOnInit() { fetch(this.url).then(res => res.json()) .then(json => { this.studentData = json; }); } } Use angular jsonPipe This is good to know, even if it is not a way to read data from a JSON file. Angular JSON pipe is mostly useful for debugging and this pipe creates a JSON representation of a data value. The JSON pipe can be used as follows: <p>{{ data | json}}</p> Thank you everyone for reading the tutorial. I hope you enhanced your knowledge of Angular.
