How to Build a Progressive Web Application (PWA) with Angular
Progressive Web Applications (PWAs) have revolutionized the way we experience the web. Combining the best of web and mobile applications, PWAs offer a seamless, fast, and reliable user experience. In this guide, we will delve into the steps of building a PWA with Angular, a powerful and widely used JavaScript framework A brief explanation of PWAs Progressive Web Applications are web applications that provide a native app-like experience to users. They can be accessed through web browsers but come with functionalities traditionally associated with native mobile apps. This includes offline access, push notifications, and the ability to install on the user's device. PWAs have gained immense popularity due to their ability to enhance user engagement and satisfaction. They bridge the gap between web and mobile, offering a responsive and reliable experience across various devices and network conditions. Studies have shown that PWAs can lead to a 76% increase in user engagement and a 38% boost in conversions compared to traditional mobile websites—source by Bootcamp. 7 Steps to Build a Progressive Web Application 1. Getting Started with Angular Before diving into PWA development, it's essential to have a solid understanding of Angular basics. Installing Node.js and npm Before diving into Angular, ensure that Node.js and npm are installed. These are essential for managing dependencies and running JavaScript on the server. Installing Angular CLI Angular CLI (Command Line Interface) simplifies the process of creating and managing Angular projects. Install it globally to access powerful commands for project management. Creating a new Angular project Use Angular CLI to create a new project. This command sets up the basic structure of your application and installs necessary dependencies. Understanding the project structure Familiarize yourself with the Angular project structure. This understanding will be crucial as you progress with designing and developing your PWA. 2. Designing Your PWA The design phase is crucial for creating a user-friendly and engaging PWA. Consider the following aspects: You can also check additional principles on responsive designs User interface and layout considerations Craft an intuitive and visually appealing user interface. Consider user experience and design principles to create a layout that enhances usability. Responsiveness and mobile-first design Ensure your PWA is responsive, adapting seamlessly to different screen sizes. Prioritize a mobile-first design approach for optimal user experience on various devices. Creating a basic layout using Angular components Leverage Angular components to structure and organize your application. These components enable you to build modular and reusable parts of your PWA. 3. Making Your PWA Installable Installability is a key feature of PWAs, allowing users to add them to their home screens like native apps. This involves Introduction to service workers Service workers are a cornerstone of PWAs, enabling offline functionality and background processes. Understand their role and implementation within your Angular app. Registering a service worker in your Angular app Implement service worker registration to allow your PWA to work offline and provide a reliable user experience even with limited or no internet connectivity. Implementing a manifest file A manifest file defines how your PWA appears when installed on a user's device. Customize this file to enhance the app's appearance and behavior. Adding an "Add to Home Screen" feature Encourage users to install your PWA on their home screen for quick access. Implement this feature to enhance user convenience. Also, check: the pros and Cons of PWA 4. Implementing Offline Capabilities Offline support is a hallmark of PWAs, allowing users to access content and functionality without an internet connection. To achieve this: Caching static assets Optimize your PWA's performance by caching static assets. This ensures quick loading times, even in offline mode. Caching dynamic content using service workers Extend caching to dynamic content, allowing users to access essential information even when offline. Handling offline data synchronization Implement strategies to synchronize data when the device reconnects to the internet, ensuring the PWA remains up-to-date. 5. Enhancing Performance Performance is crucial for a positive user experience. Optimize your PWA by: You can also check web performance guidelines for optimizing the PWA Lazy loading modules Improve performance by implementing lazy loading for modules. This allows the application to load only the necessary components when needed. Optimizing images and assets Optimize images and assets to reduce load times, contributing to a smoother user experience. Minimizing HTTP requests Minimize the number of HTTP requests your PWA makes to enhance speed and efficiency. Angular performance best practices Adopt best practices recommended by Angular for optimal performance. This includes efficient data binding and module structuring. 6. Improving User Experience Beyond the core features, PWAs can enhance user experience through additional features Implementing push notifications Enhance user engagement by incorporating push notifications. Keep users informed about updates and relevant information. Implementing background sync Enable background synchronization to ensure data is updated even when the app is not actively in use. Creating a smooth navigation experience Prioritize smooth navigation within your PWA, providing users with an intuitive and enjoyable journey through your application. Implementing offline fallback pages Prepare for unexpected scenarios by creating offline fallback pages. This ensures users still have access to critical information when offline.

When should you not use PWA? PWAs may not be suitable for every scenario. Avoid using them if your application requires extensive native device functionality that cannot be replicated in a web environment.
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 contain 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": { } } Also Check:- Angular Vs React For Web Development: How To Make The Right Choice? 2. Using Angular HttpClient A second way to read a JSON in Angular 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 Conclusion Reading and managing JSON files in Angular is an important skill for handling data effectively, especially for modern web applications.
