Most important questions for any business willing to develop an application is that “which front-end technology (client-side) should they choose?” With so many options for JavaScript frameworks available in the app development sphere, your app development team needs to be cautious about their choice.

In this top-notch technology world, your app development company or in-house team needs a better way to develop and deploy an interactive web app for your business that will earn you the desired ROI. Being an entrepreneur or business owner, you need to keep your tech guide handy for better decision making. Well, I have seen my clients getting confused about the front-end technology and curious to know more about it.

This article holds a clear detail about ReactJS vs AngularJS vs VueJS and which technology to select for your web app in 2019.

What is AngularJS?
AngularJS is an open-source front-end web app framework by Google that holds a Model-View-Controller (MVC) architecture, makes the development, maintenance and testing easier for developers. It’s great for building highly active and interactive web applications but most popular for Single page applications.

Source

AngularJS is used for web apps that are based on:

  • HTML
  • CSS
  • JavaScript

What is React JS?
Introduced by Facebook, ReactJS is an Open-Source JavaScript library for building an interactive, stateful & reusable user interface (UI). It is good for rendering complex UI with high performances and also works with the basic fundamental of virtual Document Object Model (DOM) to offer a highly stable web application.

What is VueJS?
Vue.js is a progressive JavaScript Framework for building web user interfaces. Vue is designed from the ground up to be incrementally adoptable. It comes with various optional tools for building user interfaces. Vue has a high capability of backing sophisticated Single-Page Applications when used in combination with modern tooling and supporting libraries.

Popularity

Well, if you see the analytics snapshot of Google trends, Angular was very popular till 2016, but from 2017 the searches for React is growing.

The Stackoverflow also shows the popularity of tag “AngularJS” and “ReactJS” and “VueJS” and the popularity of ReactJS is dominating now.

With every new update, ReactJS, AngularJS, and VueJS come with new features which further offer reliability and stability to the web apps.

Difference between AngularJS, ReactJS, and VueJS

Benefits of AngularJS:

  • Web application built on AngularJS runs in any browser environment regardless of the platform.
  • The two-way or bidirectional data binding ensures the data change in the model will reflect in the view immediately, and when data in the view changes, the model is also updated.
  • The pre-built material design components help in building a highly interactive and easily navigable UI for your mobile/web app.
  • The Angular Command Line Interface ensures easy update of components from third-party which reduces the time to create apps and deploy the same.

Benefits of ReactJS:

  • Virtual DOM helps React app developers an easy rendering of any changes in the application without affecting the other parts of the interface.
  • js allows the reusing of its code components anytime for different levels. This makes app development easy and time-saving.
  • ReactJS uses Redux which simplifies the storing and managing component states in large applications.
  • The unidirectional data binding makes the code stable and supports future development as the data flow is directed towards one direction.

Benefits of VueJS

  • One of the most significant benefits of Vue.js is its small size. It takes less time for the user to download and use it.
  • It facilitates web developers to integrate with the existing applications built-on JavaScript.
  • It comes with detailed documentation that helps developers to build both small as well as large scales templates saving a lot of time.
  • It allows developers to write his template in HTML file, JavaScript file, and pure JavaScript file using virtual nodes.
  • Its MVVM architecture makes it quite easy to handle HTML blocks.

How to choose between AngularJS and ReactJS for your app development?

  1. Performance
    Being the most important aspect of front-end application’s performance, HTML requires much attention from the developers. You must know that both ReactJS and AngularJS take completely different approaches to update the HTML that in turn affect the performance.

However, considering the direct changes in DOM in the browser, AngularJS is best suited for Single-page application (like Upwork) where the content is updated occasionally. And, on the other hand, ReactJS can be selected for applications of any size, which needs content update regularly (for example Instagram).

While talking about Vue.js performance, its core library is focused on the view layer only and is easy to pick up & integrate with other libraries or existing applications. Vue.js also comes with virtual DOM delivering high performance and memory allocation.

However, these three frameworks are comparatively faster than other JavaScript frameworks.

  1. Speed of development
    Though modification is easy on both ReactJS library and AngularJS framework, the speed depends on the number of libraries with the functionalities that are available to the developers. ReactJS’s architecture is easier to scale than AngularJS, but developing a web app in Angular is faster than ReactJS.

For rendering a relatively complex UI with some user interaction, all the three frameworks are a great choice. But, if you are looking for something that you can add to your app instantly, Vue is an excellent choice. Vue makes it easy to go from prototype to product.

Well, it also depends on external factors like your web app development team and their strength to overcome any complexity while developing the app.

  1. Size of the app
    The AngularJS framework holds all the necessary parts of a Minimum Viable Product to produce a fully functional Single-page application. If you want to regulate the size of your app and keep it small & compact then Angular JS is the best choice.

On the other hand, React JS is a great choice for the applications that you desire to expand in the future across multiple operating systems.

The Vue.js core library is created to be focused and flexible. The ecosystem comes with a set of tools & libraries on how to build large SPAs with Vue.

Vue.js is great for applications of any size: single-file components, highly modular component interface, platform options with Vue CLI3 etc. So, if you are using it for a moderately complex single page and other larger-scale apps that include navigation between multiple pages, it will work well.

  1. Search Engine Optimization
    Developing an amazing web app is not all, you need to look after its visibility over the internet as well. Both ReactJS and AngularJS allows you to make a Single-page application SEO-friendly, but AngularJS demands more effort to make it SEO-friendly.

According to a study, 56% of JavaScript websites lose their Google rankings due to bad SEO activities or JavaScript handling. Similar, like ReactJs and AngularJs, Vue.js also requires some strong SEO strategy.

Finally, it may be concluded

While ReactJS gives you flexibility and simplicity, AngularJS is a comprehensive framework. But that doesn’t help a lot when developers don’t need most of the features that Angular provides. Due to Reactjs’s implementation with a virtual DOM, it guarantees better performances than Angular.

Being a progressive framework, Vue can be combined into an existing project. It comes with a vast set of tools and companion libraries that allows the framework to respond to the complex needs of enterprise-grade applications. Also, with Vue CLI 3 and Vue UI, it is great for quickly delivering MVPs. Vue.js is also a cost-effective solution for small & medium applications.

However, it is simply impractical to differentiate AngularJS and ReactJS. As from the blog, you can understand both ReactJS and AngularJS are front-end technologies that require a good hand-on exposure of HTML, CSS & Java to have better productivity.

Pagination in ReactJs

Pagination in ReactJs

There are a lot of resourceful materials online that give good insights into pagination in ReactJs, as well as NPM packages you can easily use

There are a lot of resourceful materials online that give good insights into pagination in ReactJs, as well as NPM packages you can easily use. As much as I appreciate those materials and love to use those packages, they mostly deal with loading the whole dataset on the page first then completely handle the pagination in the frontend. I am approaching this article with the concept of loading the exact data needed on the page, then manually loading other dataset based on the request when the user clicks the pagination number display. Below is the content structure to guide us through this article:

Table of Contents
  • Project Setup
  • HTML and CSS Styling
  • Pagination Data Format
  • Sample API request
  • Displaying the initial data
  • Showing Page Number and getting Other data
Project Setup

We are going to use create-react-app v0.1.0 which has the CSS Module configured already. Open your terminal and cd to the folder you want the project installed. Then run the below command:

npx create-react-app pagination  --use-npm

The above command will download the project into the folder calledpagination. You need to cd into the folder and run npm start. If everything goes well, you will have a page that looks like below:

HTML and CSS Styling

Open the project in your favorite code editor and locate the App.js file, We need to prepare our App.js to the look exactly like the way we want it by adding the HTML code and CSS style below:

Create a new file called App.module.css in the same directory where you have your App.js, then import it into your App.js using:

import styles from './App.module.css';

I want us to handle the display of the pagination number first, below is the style and HTML structure of what we are going to use.

  render() {
    

    return (
      <div className={styles.app}>
        
        <table className={styles.table}>
          <thead>
            <tr>
              <th>S/N</th>
              <th>First Name</th>
              <th>Last Name</th>
            </tr>
          </thead>
          <tbody>

pagination_app.module.css

Sorry for the plenty code written so far :), I want us to have a good looking table with pagination style in place before we move into the actual paging. If everything goes well, your view should look like below:

Pagination Data Format

In most cases, when you are making API calls to an endpoint that returns a paginated data, you need to pass at least the page number with the URL, hence a sample URL will look like below:

https://reqres.in/api/users?page=2

The most important thing to take note of in the URL above is the page=2 where 2 is the page number dataset we want to get. It can be 3,4 or any number as much as the dataset we have in the backend.

The response will always contain three important data which are per_page, total and the actual data we want to loop through. A sample response looks like below:

Sample API request

Talking about making an API request to the backend, We need a backend to make the request to, I decide to use https://reqres.in/ as the API endpoint for this tutorial because it is free, always available and reliable. You can decide to make your API request directly inside your component’s ComponentDidMount() or dispatch an action to redux from your ComponentDidMount() but for the purpose of this tutorial, we are going to make the API call from the App.js componentDidMount().

Firstly, we need to set the component’s state like below inside your App.js

  state = {
    users: null,
    total: null,
    per_page: null,
    current_page: null
  }

pagination_component_state.js

users is going to be the data we are going to loop over, while total and per_page is going to help us with calculating paging logic while the current_page will be used to style the active pagination link.

The next thing we should do is create a helper method that will serve the purpose of making an HTTP request to the API endpoint and also update the state with the response data. The method will look like below:

  makeHttpRequestWithPage = async pageNumber => {
    let response = await fetch(`https://reqres.in/api/users?page=${pageNumber}`, {
      method: 'GET',
      headers: {
        'Accept': 'application/json',
        'Content-Type': 'application/json',
      },
    });

    const data = await response.json();

    this.setState({
      users: data.data,
      total: data.total,
      per_page: data.per_page,
      current_page: data.page,
    });
  }

pagination_http_request.js

This method will accept a parameter called pageNumber so it can be reusable and will always update the state with the right data when the response is successful.

Since on page load, we need to make the HTTP request to the backend, and we are going to do this inside thecomponentDidMount() by calling the method above and passing it the first-page number we want which should be 1. Hence, the componentDidMount() will look like below:

 componentDidMount() {
    this.makeHttpRequestWithPage(1);
  }

pagination_componentDidMount.js

If we add console.dir(this.state.users) inside the render() method, below will be printed in the console

The null was before the data arrived, once the data arrived, it updates the state, hence the array of users data.

Displaying the initial data

Haven gotten the data needed, we need to loop through the data and display it. Hence we can update our render method to have below:

    let users;

    if (this.state.users !== null) {
      users = this.state.users.map(user => (
        <tr key={user.id}>
          <td>{user.id}</td>
          <td>{user.first_name}</td>
          <td>{user.last_name}</td>
        </tr>
      )); 
    }
    
    return (
      <div className={styles.app}>
        
        <table className={styles.table}>
          <thead>
            <tr>
              <th>S/N</th>
              <th>First Name</th>
              <th>Last Name</th>
            </tr>
          </thead>
          <tbody>
              { users }
          </tbody>
        </table>


        <div className={styles.pagination}>
          <span>&laquo;</span>
          <span className={styles.active}>1</span>
          <span>2</span>
          <span>3</span>
          <span>4</span>
          <span>&raquo;</span>
        </div>

      </div>
    );

gistfile1.txt

I replaced the dummy data we had inside the with the result of the loop which I equated to users. We have the assurance that when the state changes, ReactJs will automatically update the content of the table. The final stage is displaying the page logic and getting the other contents based on the page number clicked which will be sent to the API endpoint.

Showing Page Number and getting other data

Before we talk about showing page number automatically using the desired logic, I want us to manually show those numbers and make the actual API calls when the numbers are clicked. For now, we are going to hard code the pagination numbers ourselves like below:

<div className={styles.pagination}>
  <span onClick={() => this.makeHttpRequestWithPage(1)}>1</span>
  <span onClick={() => this.makeHttpRequestWithPage(2)}>2</span>
  <span onClick={() => this.makeHttpRequestWithPage(3)}>3</span>
  <span onClick={() => this.makeHttpRequestWithPage(4)}>4</span>
</div>

pagination_hard_code.js

The above code will look like below when previewed in the browser.

Notice that each span has an event handler attached to it, and I passed the page number to that event handler, so anytime we click on the pagination link, it will make a new HTTP request and update the component states, hence the user’s table data. We do not want to hard-code the links as we did above, so we need to automatically display those links.

So we’re planning on showing the page numbers for a series of pieces of data so that users can easily navigate multiple items. There are a few things that we need to know first:

  • The page that we’re on
  • Total number of items
  • Number of items per page

Good news is that we have captured all these things in our component’s state.

Next, we need to look at how we want to display the page numbers, there is a wide range of methods that people use:

  • Simple Next/Previous buttons with no numbers
  • A list of all possible pages
  • Page 1 & the last page, with the current page (and 2 above/below) shown

I personally prefer to show the very first page, that last page, and then the current page with 2 pages above & below. So for example on page 12 out of 24 pages we’d see:

1, 10, 11, 12, 13, 14, 24

This allows users to quickly navigate to the start, and to the end, as well as jump through multiple pages at once. For the purpose of this tutorial, I am going to show us how to show a list of all possible pages(item two above) then item three too.

The Arithmetic

We need to work out the total number of pages, for this, we want to take the total number of items that there are, and divide it by the number of items per page. But we want to make sure that we take that number and round it up.

So if there were 12 items in total, and we were showing 5 per page, we’d have a total of 3 pages of items. If we were to show 3 per page, we’d show 4 pages.

const pageNumbers = [];
for (let i = 1; i <= Math.ceil(this.state.meta.total / this.state.meta.per_page); i++) {
    pageNumbers.push(i);
}

page_logic_pagination.js

Haven gotten the page numbers, we need to loop through to display the span since we want to show all possible numbers first, our loop will look like below:

renderPageNumbers = pageNumbers.map(number => {
  let classes = this.state.current_page === number ? styles.active : '';

  return (
    <span key={number} className={classes} onClick={() => this.makeHttpRequestWithPage(number)}>{number}</span>
  );
});

pagination_all_numbers_loop.js

We need to update our pagination view to look like below:

<div className={styles.pagination}>
  <span onClick={() => this.makeHttpRequestWithPage(1)}>&laquo;</span>
  {renderPageNumbers}
</div>

pagination_view._01js

Congrats, we have successfully handle pagination, make HTTP request to the backend and changing the table content when user click on the page number to see.

To be sure we are on the same page, my App.js code looks like below:

import React, { Component } from 'react';
import styles from './App.module.css';

class App extends Component {


  state = {
    users: null,
    total: null,
    per_page: null,
    current_page: 1
  }


  componentDidMount() {
    this.makeHttpRequestWithPage(1);
  }


  makeHttpRequestWithPage = async pageNumber => {
    const response = await fetch(`https://reqres.in/api/users?page=${pageNumber}`, {
      method: 'GET',
      headers: {
        'Accept': 'application/json',
        'Content-Type': 'application/json',
      },
    });

    const data = await response.json();

    this.setState({
      users: data.data,
      total: data.total,
      per_page: data.per_page,
      current_page: data.page
    });
  }


  render() {

    let users, renderPageNumbers;

    if (this.state.users !== null) {
      users = this.state.users.map(user => (
        <tr key={user.id}>
          <td>{user.id}</td>
          <td>{user.first_name}</td>
          <td>{user.last_name}</td>
        </tr>
      ));
    }

    const pageNumbers = [];
    if (this.state.total !== null) {
      for (let i = 1; i <= Math.ceil(this.state.total / this.state.per_page); i++) {
        pageNumbers.push(i);
      }


      renderPageNumbers = pageNumbers.map(number => {
        let classes = this.state.current_page === number ? styles.active : '';

        return (
          <span key={number} className={classes} onClick={() => this.makeHttpRequestWithPage(number)}>{number}</span>
        );
      });
    }

    return (


      <div className={styles.app}>

        <table className={styles.table}>
          <thead>
            <tr>
              <th>S/N</th>
              <th>First Name</th>
              <th>Last Name</th>
            </tr>
          </thead>
          <tbody>
            {users}
          </tbody>
        </table>


        <div className={styles.pagination}>
          <span onClick={() => this.makeHttpRequestWithPage(1)}>&laquo;</span>
          {renderPageNumbers}
          <span onClick={() => this.makeHttpRequestWithPage(1)}>&raquo;</span>
        </div>

      </div>
    );
  }

}

export default App;

pagination_app.js

and my view like below:

We can change the page number display logic to below since it will accommodate for large dataset.

renderPageNumbers = pageNumbers.map(number => {
  let classes = this.state.current_page === number ? styles.active : '';

  if (number == 1 || number == this.state.total || (number >= this.state.current_page - 2 && number <= this.state.current_page + 2)) {
    return (
      <span key={number} className={classes} onClick={() => this.makeHttpRequestWithPage(number)}>{number}</span>
    );
  }
});
