The post 10 Reasons why angular is the first choice for front-end developers? appeared first on Welcome to Ahex Technologies.

Google released the next version of javascript popular framework, angular 7 which already arrived with many changes, significant updates & many new features.There are some very interesting new tooling changes as well as some great features to improve performance.

Angular 7  new features

CLI Prompts

The Angular team has consistently focused on improving the tools available to developers and the new CLI prompts are no different.

Usually when we run commands like ng new or ng add, it’s a single pass.If we forget to include routing then by skipping the installation just run ng new “myNewApp” then a prompt will be generated for adding route.

If we want to add different stylesheet format then CLI will offer to select between CSS,SCSS,SASS,LESS and more.

The great features is that it is customizable just add schematic.json using this we can tell CLI which prompt to execute.

Application performance

Angular 7 is even faster than previous versions. The upgrade is faster (less than 10 minutes for many apps according to the official announcement), the framework is faster, the virtual scrolling CDK module detailed above makes apps run with better performance.

Here is where things get interesting: Angular is not only dedicated to making the framework as small as possible, it’s also dedicated to making your apps as small as possible. They’ve corrected a common production mistake where the reflect-metadata polyfill is included in production. V7 automatically removes it.

New projects are also now defaulted using Budget Bundles which work to notify you when your app is reaching size limits. By default, you get warnings when you reach 2MB and errors at 5MB.

And when you need a little more space, just jump in your angular.json file  and adjust as necessary.

“budgets”: [{
 “type”: “initial”,
 “maximumWarning”: “2mb”,
 “maximumError”: “5mb”
}]

Virtual Scrolling

As many mobile frameworks have started to make the move toward dynamically loading data such as images or long lists, Angular has followed suit by adding the ScrollingModule to allow for virtual scrolling. As elements gain or lose visibility, they are virtually loaded and unloaded from the DOM. Performance is greatly increased to the user’s eyes. Next time you have a potentially large list of items for your users to scroll, stick it in a cdk-virtual-scroll-viewport component and take advantage of the performance boost!

Drag & Drop Functionality

Now you can remain entirely within the Angular Material module and implement drag and drop support including reordering lists and transferring items between lists. The CDK includes automatic rendering, drag handlers, drop handlers and even the ability to transfer data.

Dependency Updates In Angular 7

TypeScript 3.1 support
Angular 7 have updated TypeScript version from 2.7 to 3.1 which is it’s the latest release. It’s compulsory to use TypeScript latest version while working with Angular 7. Usually Angular lags a few releases behind, so they have done that to match latest TypeScript version for once.

RxJS 6.3

One of the popular definition of “Robotic Process Automation” is –
“An application of technology that allows employees in a company to configure computer software, or a ‘robot’, to capture and interpret existing applications for processing a transaction, manipulating data, triggering responses and communicating with other digital systems”.
-The Institute for Robotic Process Automation (IRPA)

Robotic Process Automation is not a physical robot sitting at a desk performing tasks. It is a new alternative to improve productivity, unlocking higher Return on Investment than ERP implementations and Software as a Service (SaaS) which requires more investment in terms of time and cost.
It is the first step and necessary foundation in the enterprise digital operation journey, before implementing cognitive, chatbots and artificial intelligence.

Key objectives of implementing Robotic Process Automation are as follows –

• Improve customer experience
• Improve accuracy
• Manage controls
• Higher efficiency
• Reduction of monotonous work
• Cost saving
• Skill upgradation of personnel

Robotic Process Automation (RPA) is the next phase of innovation in the world. It’s significant potential to become a differentiator has become evident. Most of the notable players are either assessing possibilities to benefit from this new solution or even proceeding with the first implementations.
Once IT and security risks are satisfied with the IT architecture, the process is documented in detail and can be carried forward for implementation.

Key sectors where RPA is playing a significant role in bringing in process efficiencies include highly regulated verticals such as,healthcare,banking, financial services and insurance. Other major sectors include telecommunications, utilities, mining, travel and retail.
Functional Areas where RPA implementation is beneficial are as under:

• Human Resources
• Payroll Administration
• Benefits Enrolment
• Data of Employees Management

• Management of Claims
• Tracking of Leave Applications
• Routine Query Management
• Finance & Accounting
• Accounts Receivable (OTC)

• Procurement/ Sourcing
• Order Management
• Invoice Processing

REST or HTTP based services are the primary requirements of single page applications to retrieve the data and gel into the web application. Angular offers its inbuilt HTTPClient service which wraps the major functions for requesting the data from server where REST service is hosted.

The Angular HttpClient API :-

Angular 4.3 introduced a new HttpClient service, which is a replacement for the Http service from Angular 2 and has it’s own package @angular/common/http. It works mostly the same as the old service, handling both single and concurrent data loading with RxJs Observables, and writing data to an API.

The HttpClient in @angular/common/http offers a simplified client Http API for Angular applications that rests on the XMLHttpRequest interface exposed by browsers. Additional benefits of HttpClient include testability features, typed request and response objects, request and response interception, Observable APIs, and streamlined error handling.

HttpClient service is included in the HttpClientModule and it can be used to initiate HTTP request.

Technologies Used :-

Find the technologies being used to build HTTPClient

1. Angular 4.3+

2. Angular CLI 1.5.4

3. TypeScript 2.4.2

4. Node.js 6.11.0

5. NPM 3.10.10

The Back-End API :-

The back-end for this app is a simple Express-based API that exposes the following endpoints:

GET/api/Authors

Returns an array of all existing Authors objects in JSON format.

POST/api/Authors

Creates a new Author object in the back-end data store. Accepts a JSON object in the request body. If successful, returns a 200 OK response, containing a JSON object representing the data as saved on the server, including the auto-numbered ID.

PUT/api/Authors/{Authors_id}

Updates an existing Author object. Accepts a JSON object in the request body. If successful, returns a 200 OK response, containing a JSON object representing the data as saved on the server.

DELETE /api/Authors/{Authors_id}

Deletes an existing Author object. Does not require a response body. If successful, returns a 200 OK response, containing a JSON object representing the Authors object as it existed before it was deleted.

Let’s see how to use the new HttpClient in Angular 4.3 project.

Setup an Angular 4.3 Project : –

The first step is to install Angular Cli command line interface.

If you have not installed Angular CLI on your system yet, you first need to execute the following command to install the latest version:

$ npm install -g @angular/cli

Now you can use the ng command to initiate a new Angular project:

$ ng new nghttp01

A new directory nghttp01 is created, the project template is downloaded and the dependencies are installed automatically.

Next open package.json in your code editor and check that all Angular dependencies contain a version number of >4.3.0.

Having updated the package.json file you need to execute the command in the project directory in order to make sure that the corresponding packages are updated.

$ npm install

Getting Started with HttpClient:-

To be able to use the HttpClient service within components you first need to include the HttpClientModule in the Angular application.

Import HttpClientmodule in the application’s root module in file app.module.ts:

Using HttpClient To Request Data :-

HttpClient will use the XMLHttpRequest browser API to execute HTTP request. In order to execute HTTP request of a specific type you can use the following methods which corresponds to HTTP verbs are

POST, GET, PUT, PATCH, DELETE, HEAD, JSONP

* To demonstrate the http methods, we would be querying a fake REST API

we create Service using angular cli. Write following angular cli command into terminal service makes the HTTP request and returns the Observable object.

$ ng g service app

It will create two files named app.service.ts and app.service.spec.ts.

Inject the HttpClient into an application class as shown in the following app.service.ts example.

import { Injectable } from '@angular/core';
import { HttpClient, HttpHeaders } from '@angular/common/http';
import { Observable } from 'rxjs/Observable'

const httpOptions = {
  headers: new HttpHeaders({ 'Content-Type': 'application/json' })
};

@Injectable()
export class AppService {

  constructor(private http : HttpClient) { }
}

One of the most notable changes is that now the response object is a JSON by default, so there’s no need to parse it anymore for example :-

/* HttpClient */
this.http.get('https://api.github.com/users')
subscribe(data => console.log(data));

Rather Than

/* Http */
this.users = this.http.get('https://api.github.com/users')
.map(response => response.json())
.subscribe(data => console.log(data));

Example of an HTTPCLIENT GET:-

on app.service.ts

import { Injectable } from '@angular/core';
import { HttpClient, HttpHeaders } from '@angular/common/http';
import { Observable } from 'rxjs/Observable'
import { Url } from './constant'

const httpOptions = {
  headers: new HttpHeaders({ 'Content-Type': 'application/json' })
};

@Injectable()
export class AppService {

  constructor(private http: HttpClient) { }
  /* Uses http.get() to load data from a single API endpoint */
  getAuthors() {
    return this.http.get(Url.baseUrl + '/api/Authors');
  }
}

A component, such as app.component injects the app.service and calls the get service method.

import { Component } from '@angular/core';
import { AppService } from './app.service';
@Component({
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.css'],
  providers: [AppService]
})
export class AppComponent {
  data: any = []
  author = {
    FirstName: '',
    ID: '',
    IDBook: '',
    LastName: ''
  }
  constructor(public appService: AppService) { }

  ngOnInit() {
    this.AuthorsPage();
  }
  /* method to call get-api from app.service */
  AuthorsPage() {
    try {
      this.appService.getAuthors()
        .subscribe(resp => {
          console.log(resp, "res");
          this.data = resp
        },
          error => {
            console.log(error, "error");
          })
    } catch (e) {
      console.log(e);
    }
  }
}

The subscribe() method takes three arguments which are event handlers. They are called onNext, onError, and onCompleted.

The onNext method will receive the HTTP response data. Observables support streams of data and can call this event handler multiple times. In the case of the HTTP request, however, the Observable will usually emit the whole data set in one call.

The onError event handler is called if the HTTP request returns an error code such as a 404.

The onCompleted event handler executes after the Observable has finished returning all its data. This is less useful in the case of the Http.get() call, because all the data we need is passed into the onNext handler.

The output which is displayed in the browser console should look like the following:

Example of an HTTPCLIENT Post :-

Next, let’s see how data can be send via HttpClient. For sending data we’ll be using the post method of the HttpClient object.

On app.service.ts :-

 /* Uses http.post() to submit data from a single API endpoint */
  submitAuthor(data) {
    return this.http.post(Url.baseUrl + '/api/Authors', data);

  }

On app.component.ts: –

  /* method to call post-api from app.service */
  submitAuth(formValues) {
    try {
      let author = {
        FirstName: formValues.FirstName,
        ID: formValues.ID,
        IDBook: formValues.IDBook,
        LastName: formValues.LastName
      }
      // console.log(author,"author")
      this.appService.submitAuthor(author)
        .subscribe(resp => {
          console.log(resp, "res");
          this.data = resp
        },
          error => {
            console.log(error, "error");
          })
    } catch (e) {
      console.log(e);
    }
  }

Here you can see that the data of the post request are passed to the post method as a second parameter in JSON format. We’re getting back a response which is confirming that the object has been created successfully.

Example of an HTTPCLIENT Put Method:-

This application update author with the HttpClient put method by passing the Author’s id and data in the request URL.

On app.service.ts

/* Uses http.put() to update data from a single API endpoint */
  updateAuthor(id,data) {
    return this.http.put('/api/Authors/' + id, data);
  }

Updating data from component:-

/* method to call put-api from app.service */
  updateFood(author,index) {
    try {
    this.appService.updateAuthor(author,index)
      .subscribe(data => {
       this.data = resp

      },
        error => {
          console.error("Error saving food!");
        }
      );
    }
    catch (e) {
      console.log(e);
    }
  }

Example of an HTTPCLIENT Delete method :-

This application deletes author with the HttpClient delete method by passing the Author’s id in the request URL.

On app.service.ts

 /* Uses http.delete() to delete data from a single API endpoint */
  deleteAuthor(id) {
    return this.http.delete(Url.baseUrl + "/api/Authors/" + id)
  }

deleting the data :-

/* method to call delete-api from app.service */
  deleteAuth(author, index) {
    try {
    this.appService.deleteAuthor(author)
      .subscribe(resp => {
        console.log(resp, "resp")

      },
        error => {
          console.log(error)
        }
      )
    }
    catch (e) {
      console.log(e);
    }
  }
