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: https://www.smashingmagazine.com/2018/11/a-complete-guide-to-routing-in-angular/
How To Read Local JSON Files In Angular: Different Ways To Do
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": "luca@gmail.com", "gender": "male" }, { "id": 2, "name": "Lilly", "email": "lilly@gmail.com", "gender": "female" }, { "id": 3, "name": "Anna", "email": "anna@gmail.com", "gender": "female" }, { "id": 4, "name": "John", "email": "john@gmail.com", "gender": "male" }, { "id": 5, "name": "Mary", "email": "mary@gmail.com", "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', this.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>{{student.name}}</td> <td>{{student.email}}</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. Download Pdf
How To Build Micro Frontend With Micro Federation in Angular?
Micro Frontends are a way to build and deliver a large application as a composition of small, independent applications. This approach enables teams to work on their own codebases and deliver new features faster, while also making it easier to scale development. Module Federation is a way to implement Micro Frontends in the Angular ecosystem. It allows multiple Angular applications to share a common set of libraries and enables them to communicate with each other using a shared API. Benefits of Building Micro Frontend with Module Federation The benefits of this include: 1. Improved scalability: By breaking the frontend application into smaller units, it becomes easier to scale individual parts of the application independently. This can be particularly useful if different parts of the application have different scaling needs. 2. Enhanced maintainability: Decomposing the frontend application into smaller, self-contained units make it easier to understand and maintain the codebase. This can be especially useful in large organizations where multiple teams are working on the same codebase. 3. Faster deployment: Because microfrontends and module federation allows for independent deployment of different parts of the frontend application, it becomes possible to deploy changes to production more quickly. 4. Improved code reuse: Decomposing the frontend application into smaller units makes it easier to reuse code across different parts of the application. 5. Better team autonomy: By allowing teams to work on self-contained units of the frontend application, microfrontends and module federation can improve team autonomy and reduce dependencies between teams. Steps to Create Micro Frontend Let's get started and create a small microfrontend. Before starting please make sure you have the following prerequisites * Have some basic knowledge of Angular and Angular CLI. * A system with NodeJs and Angular CLI already installed * Angular and Angular CLI needs to be atleast 14 or higher Angular's Module Federation team has conveniently provided a starter kit for this. So let's first clone their repo and download the dependencies with the following commands git clone https://github.com/manfredsteyer/module-federation-plugin-example.git --branch starter cd module-federation-plugin-example npm i In the project, if you have already noticed there are 2 folders in the project folder. One is shell and the other is mfe1. In this example, the 'shell' will be the host while mfe1 will be the microfrontend Inside mfe1 there is a flights module at projects/mfe1/src/app/flights that we will be going to load through the shell. You can individually serve them using ng serve shell -o and ng serve mfe1 -o to serve the application individually. Now, let's activate and configure module federation: Install @angular-architects/module-federation into them: ng add @angular-architects/module-federation --project shell --type host --port 4200 ng add @angular-architects/module-federation --project mfe1 --type remote --port 4201 This activates module federation, assigns a port for ng serve and generates the skeleton of a module federation configuration. Now, let's start configuring the microfrontend. Open the file projects\mfe1\webpack.config.js. This is where it is defined what you are exposing to the host. By default, you will be exposing the app.component.ts file. Instead, let's expose the Flights module. So replace the entire exposes object with exposes: { './Module': './projects/mfe1/src/app/flights/flights.module.ts', }, This is basically saying to expose the flights module to any hosts that use mfe1. Similarly, if you open the shell’s config file ‘projects\shell\webpack.config.js’ you will notice instead of exposes there is a remotes object. This basically says to the Host that there is a remote mfe1 which can be referenced in its router. Make sure that mfe1’s port is 4201 instead of 4200 remotes: { mfe1: 'http://localhost:4201/remoteEntry.js', }, This references the separately compiled and deployed mfe1 project. Now let's load reference the microfrontend in the shell’s router. Open projects\shell\src\app\app.routes.ts and add a route to the Micro Frontend { path: 'flights', loadChildren: () => import('mfe1/Module').then(m => m.FlightsModule) }, Please note that the imported URL consists of the names defined in the configuration files above. So depending on what you assign in expose object the import URL changes import('mfe1/Module'). You will notice a red squiggly line under 'mfe1/Module'. That is because the URL does not exist at the time of compilation. So to stop the Typescript compiler from complaining about it declare the module in the projects\shell\src\decl.d.ts file. declare module 'mfe1/Module'; Now everything is configured so now it's time to try it out. Serve both the shell and mfe1 in separate terminals ng serve shell -o ng serve mfe1 -o After a browser window with shell opened (http://localhost:4200), click on Flights. This should load the Micro Frontend into the shell. Also, ensure that the Micro Frontend also runs in standalone mode at http://localhost:4201. Congratulations! You've implemented your first Module Federation project with Angular! Now time for some tips and tricks You can dynamically load remotes directly in app.routes.ts rather than in the webpack.config.js So first, comment the remote mfe1 property in projects\shell\webpack.config.js. remotes: { // Comment this line: // "mfe1": "http://localhost:4201/remoteEntry.js", }, Then in the app.routes.ts use the function loadRemoteModule instead of the dynamic import statement: import { loadRemoteModule } from '@angular-architects/module-federation'; const routes: Routes = [ [...] { path: 'flights', loadChildren: () => loadRemoteModule({ type: 'module', remoteEntry: 'http://localhost:4201/remoteEntry.js', exposedModule: './Module' }).then(m => m.FlightsModule) }, [...] ] Restart both, the shell and the micro frontend (mfe1). The shell should still be able to load the microfrontend. However, now it's loaded dynamically. Conclusion Microfrontends are not for every application as it requires considerable time and effort not just to create and introduce it into your codebase but also to maintain it. It gets a bit more complicated when you want to have shared states and bidirectional data passing. In most small to medium size projects, the benefits do not outweigh the cost, but in most large-scale projects where you want to have independent teams managing parts of the project, it is highly recommended to implement Module Federation. This situation may change in the future as the Angular Module Federation team is working hard to make it much more accessible and easy to use.
