Top 10 Most Used Frameworks in The World

Introduction:

In today’s age, websites have become the most important factor for businesses to evolve around their customers. Also, most of the business customers come from around the mobile phones. So the importance of web applications has increased greatly.

In this blog, we will tell you about web frameworks and the most used web frameworks in the world.

What are Web Frameworks?

Web Frameworks, sometimes called Web Application Frameworks, are software platforms that help create web applications.

Types of Web Frameworks:

1. Front-End Frameworks (Client-side Frameworks):

Front-end frameworks are used to create the user interface for user-friendly interaction.

2. Back-end Frameworks (Server-side Frameworks):

Developers use back-end frameworks on the backend of a website to ensure its smooth functioning.

10 Most Used Web Frameworks:

Following we have created a list of the top 10 most used web frameworks in the World:

1. Node.js:

Node.js is a free and open-source server environment that is compatible with various operating systems, such as Windows, Linux, Unix, and Mac. Developers use it for running web applications outside of the user’s web browser. Node.js’ ability to run JavaScript code on the server is often used to generate dynamic page content.

2. React:

React, sometimes called as a front-end JavaScript framework, is a JavaScript library created and managed by Meta. It is an open-source JavaScript library for building user interfaces based on components. React is used to create single-page web applications.

3. JQuery:

JQuery is a small, fast and lightweight JavaScript library. It is a free and open-source software under the MIT Licence. JQuery simplifies a lot of complicated things from Java scripts such as DOM manipulation and Ajax Calls.

4. Express.js:

Express.js is a backend web application framework for building RESTful APIs with Node.js. It is a free and open-source software under the MIT Licence. It is used to create single-page, multi-page and hybrid web applications.

5. Angular:

Angular is a popular open-source front-end web application framework developed and maintained by Google. Angular, written in TypeScript, enables developers to build dynamic, single-page web applications (SPAs) with a modular and maintainable code structure.

6. Next.js:

Next.js is a React framework for building full-stack web applications. It enables several extra features for React, including server-side rendering and generating static websites. It is one of the most popular frameworks for React.

7. ASP.NET Core:

ASP.NET Core is an open-source, cross-platform framework developed and managed by Microsoft to build modern, cloud-based, scalable web applications. It is a redesign of the original ASP.NET framework, providing improved modularity, performance, and flexibility.

8. Vue.js:

Vue.js is a front-end open-source JavaScript library for building user interfaces and single-page web applications. Evan You released it in 2014. From then it has gained popularity for its simplicity, reactivity system, and ease of integration.

9. Flask:

Flask is a micro web framework written in Python. People refer to Flask as a microweb framework because it does not require particular tools or libraries. It has no database abstraction layer, form validation, or other components where pre-existing third-party libraries provide common functions.

10. Django:

Django is a free and open-source, Python-based web framework that runs on the web server. It follows the Model-View-Controller (MVC) architectural pattern. It provides a robust and scalable infrastructure for building web applications.

Conclusion:

In Conclusion, this blog delved into the realm of web frameworks, distinguishing between front-end and back-end frameworks and spotlighting the top 10 widely utilised frameworks globally.

Angular 7 - CRUD Operations

This is very huge post which covers most of the angular concepts , so please be patient and go through it. This post is related to angular CRUD operations using angular AG grid and REST webservices in java. We will go through below concepts while going through these post - REST API in javaAG Grid in javaBootstrap Configuration Notifications service configurationReactive forms in angularForm ValidationsService in angularCalling REST API using HttpClientRouting and Navigation 1.REST API in java We would need to create a REST API which supports CRUD operations on user data as below - package com.myjavablog.controller; import com.myjavablog.entity.User; import com.myjavablog.repository.UserRepository; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.web.bind.annotation.*; import java.util.List; import java.util.Optional; @CrossOrigin @RestController @RequestMapping("/api") public class UserController { @Autowired private UserRepository userRepository; @GetMapping("/users") public List getUsers(){ return userRepository.findAll(); } @GetMapping("/user/{id}") public Optional getUser(@PathVariable Long id){ return userRepository.findById(id); } @DeleteMapping("/user/{id}") public boolean deleteUser(@PathVariable Long id){ userRepository.deleteById(id); return true; } @PostMapping("/user") public User createUser(@RequestBody User user){ return userRepository.save(user); } @PutMapping("/user") public User updateUser(@RequestBody User user){ return userRepository.save(user); } } This is the controller in java which supports GET,UPDATE,PUT,POST operations on USER data. You can download the entire code from below Github link - Download 2. AG Grid in java Before actually going into angular project, you can go through my older posts on how to create angular project. http://www.myjavablog.com/2019/04/13/angular-installation-and-setup/ Once the project is created you need to install ag-grid support to it. Below packages needs to be installed for the same - npm i --save ag-grid You need to import this dependency in app.module.ts by adding below line under imports - AgGridModule.withComponents(null) Also you need to add CSS support for grid in styles.css - @import 'ag-grid-community/dist/styles/ag-grid.css'; @import 'ag-grid-community/dist/styles/ag-theme-blue.css Then create a component using below command - ng n c user This will create new user component and create CSS, TS , html files. Add code to html file for grid -

Angular 7 AG Grid CRUD Operations Example

Add User Edit User Delete User All the options specified in grid configuration are self explanatory. You also need Typescript file in order to perform CRUD operations . You get this from my github link. 3. Bootstrap Configuration First install bootstrap by using below npm command - npm install bootstrap Then Add bootstrap to angular.json under styles- "styles": , 4. Notifications service configuration This service is to show the notifications to users. Use below npm command to install - npm install angular-notifier Add it into imports in app.module.ts and add custom options as well- NotifierModule.withConfig( customNotifierOptions ) /** * Custom angular notifier options */ const customNotifierOptions: NotifierOptions = { position: { horizontal: { position: 'middle', distance: 12 }, vertical: { position: 'top', distance: 12, gap: 10 } }, theme: 'material', behaviour: { autoHide: 5000, onClick: false, onMouseover: 'pauseAutoHide', showDismissButton: true, stacking: 4 }, animations: { enabled: true, show: { preset: 'slide', speed: 300, easing: 'ease' }, hide: { preset: 'fade', speed: 300, easing: 'ease', offset: 50 }, shift: { speed: 300, easing: 'ease' }, overlap: 150 } }; Also you would need to add CSS for notifier in app.component.html file as below - 5. Reactive forms in angular Now you need to create user form to add users -

Add User

First Name: First name is required Last Name: Last name is required Email address: Email is required Age: Age is required Mobile: Mobile number is required Submit Invalid credentials. Back 6. Form Validations With reactive forms ,you can associate FormGroup and FormBuilder and access the form fields . Using these objects , you can also validate the form fields using angular Validators. 7. Services in Angular We have to write the service to call the REST APIs and perform CRUD operations as below - Create service using - ng g s user import { Injectable } from '@angular/core'; import { User } from './../model/user'; import {HttpClient} from '@angular/common/http'; @Injectable({ providedIn: 'root' }) export class UserService { apiUrl:string = "http://localhost:8081/api/"; constructor(private http : HttpClient) { } getUsers() { return this.http.get(this.apiUrl+'users'); } deleteUser(userId: number){ return this.http.delete(this.apiUrl+'user/'+userId); } addUser(user: User){ console.log(user); return this.http.post(this.apiUrl+ 'user/', user ); } editUser(user: User){ console.log(user); return this.http.put(this.apiUrl+ 'user/', user ); } } 8. Calling REST API using HttpClient In above service, we are injecting HttpClient in constructor to call the REST API. 9. Routing and Navigation We would need to provide routing for our application. So specific URI will be served by specific Component. Route configuration is provided in app-routing.module.ts as below - import { NgModule } from '@angular/core'; import { Routes, RouterModule } from '@angular/router'; import { LoginComponent } from './components/login/login.component'; import { UserComponent } from './components/user/user.component'; import { AddUserComponent } from './components/user/add-user/add-user.component'; const routes: Routes = ; @NgModule({ imports: , exports: }) export class AppRoutingModule { } You can download the code for this application from below github link - Download Now build the application and serve it to the client - ng build ng serve Now the application is ready to access on http://localhost:4200/-
