Vue.js – Simple Pagination Example

kishan kumar — Sun, 08 Mar 2020 14:25:29 +0000

This is a simple example of how to implement Vue.js – Simple Pagination in Vue.js.

Running the Vue.js Pagination Example Locally

Install NodeJS and NPM from https://nodejs.org.
Download or clone the tutorial project source code from https://github.com/Appfinz/vue-js-pagination-with-easy-steps.git
Install all required npm packages by running the npm install command in the project root folder (where the package.json is located).
Start the Vue.js app by running npm start in the project root folder, this will build the app with webpack and automatically launch it in a browser on the URL http://localhost:8080.

Vue.js Pagination Component

Pagination is implemented with the <jw-pagination> component that comes with the jw-vue-pagination package available on npm.

Installation

Install the Vue pagination component with the command npm install jw-vue-pagination.

Integration with your Vue.js app

Import the JwPagination component from the 'jw-vue-pagination' package and register it globally within your Vue application by calling Vue.component('jw-pagination', JwPagination);

The first parameter is the component name, it defines the custom tag used to add the component to other components, in this case it will be with the tag <jw-pagination></jw-pagination>. The second parameter points to the actual Vue component.

Global registration makes the Vue component available to all other components within the Vue application, it’s also possible to register components locally, for more info see https://vuejs.org/v2/guide/components-registration.html.

This is the main Vue entry file (/src/index.js) from the example, the pagination component is imported and registered globally on lines 6-7.

import Vue from "vue";

import App from "./app/App";

// register jw pagination component globally
import JwPagination from 'jw-vue-pagination';
Vue.component('jw-pagination', JwPagination);

new Vue({
el: "#app",
render: h => h(App)
});

Vue.js + Node – Server Side Pagination

kishan kumar — Sun, 08 Mar 2020 14:12:20 +0000

This is a simple example of how to implement server-side pagination in Vue.js with a Node.js backend API.

Server-Side (Node.js) Pagination Logic
Below is the code for the paged items route (/api/items) in the node server file (/server/server.js) in the example, it creates a hardcoded list of 150 items to be paged, in a real application you would replace this with real data (e.g. from a database). The route accepts an optional page the parameter in the URL query string if the parameter isn’t set it defaults to the first page.

The paginate() the function is from the jw-paginate package and accepts the following parameters:

total items (required) – the total number of items to be paged
currentPage (optional) – the currently active page defaults to the first page

pageSize (optional) – the number of items per page defaults to 10
maxPages (optional) – the maximum number of page navigation links to display, defaults to 10
The output of the paginate function is a pager object containing all the information needed to get the current pageOfItems out of the items array, and to display the pagination controls in the Vue.js frontend, including:

startIndex – the index of the first item of the current page (e.g. 0)
endIndex – the index of the last item of the current page (e.g. 9)
pages – the array of page numbers to display (e.g. [ 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 ])
currentPage – the currently active page (e.g. 1)
totalPages – the total number of pages (e.g. 30)
I’ve set the pageSize to 5 in the CodeSandbox example above so, the pagination links aren’t hidden below the terminal console when the container starts up. In the code on GitHub, I didn’t set the page size so the default 10 items are displayed per page in that version.

The current pageOfItems is extracted from the items array using the startIndex and endIndex from the pager object. The route then returns the pager object and current page of items in a JSON response.

Major Differences Between Ionic React Vs React Native

kishan kumar — Sun, 08 Mar 2020 12:35:04 +0000

Ionic and React Native are two of the most popular mobile app development tools for building mobile apps. Originally released in 2013, Ionic React is an open-source UI project with the Native API that contains native operating platforms that make it easy to build iOS, Android, and web applications as a developing web app. React native was released in 2015 to build apps using Javascript only. Although both are great frameworks used to build platform systems, there are many ways in which they work differently from one another. In this blog, we will discuss the major differences between the Ionic React vs React Native for mobile app development.

Ionic React

Ionic React opens up the Ionic Framework to a whole new audience. This is the biggest change in the history of the Ionic framework. Ionic React integrates centralized Ionic experience with APIs developed for React Developers. With Ionic React we can import basic Ionic elements directly into your React project. Ionic React acts as a small wrapper around the export elements like Native React elements. It enables Ionic to react naturally while working in React. This provides many response paradigms that have not been there in the mainstream.

Web designers around the world use Ionic React as a version of Revenue that enables Mission, Crazy Programs for companies like Amtrak, AAA, Burger King, Home Depot, and a few others. Ionic app development companies enable them to build high-quality applications using their existing web development capabilities.

While the former Ionic supports Cordova, the traditional version of the Ionic Upwork Framework runs on a new platform engine called Capacitor. The capacitor engine provides a set of consistent, web-based APIs that allow the app to stay as close to the web standards as possible while accessing the rich features of the traditional device on the supporting devices.

Highlights of Ionic React

Local Functionality

Ionic additionally gives local usefulness that bolsters it gets straightforwardly from the clients. Such usefulness incorporates secure validation and personality the board utilizing propelled encryption APIs accessible on iOS and Android, superior disconnected encoded information stockpiling, and a library of upheld and kept up local usefulness.

Build Fast and Beautiful Mobile Applications

Ionic React is an open-source programming advancement unit driving a large number of wonderful applications, modified to fit with any brand.

Better comparability with React DOM

Ionic React influences React DOM which is one of the most famous rendering libraries for React. It has more use and in this way has better similarity with the React biological system which empowers it to work with any React library.

Different stages support

Ionic React utilizes an undertaking made at Ionic named Capacitor which empowers designers to call local code straightforwardly from JavaScript and uncover new local usefulness or showing Native UI is simple. This local runtime can be conveyed to local iOS, Android, Electron, and the web as a Progressive Web App.

Creating a simple website with Node.js, Express, and EJS

What is the difference between React Native and React?

kishan kumar — Sat, 07 Mar 2020 17:53:36 +0000

React.js was created by Facebook to address its requirement for a dynamic and high performing User Interface(UI). In 2011, Jordan Walke and his group from Facebook discharged the React JS library, a JavaScript library that united the speed of JavaScript and another method for rendering pages, prompting responsive and dynamic client input. In 2015, two years after the group publicly released React.js and its ubiquity developed, they discharged React Native.

Respond Native was created and propelled by Facebook Developers Community in 2015 and turned out to be a serious intriguing part among versatile application engineers.

It very well may be utilized for building cross-stage portable applications. The structure was later modified by supporters of utilization it for building work area applications too.

Check Out This React + Node.js App on AWS EC2

Despite the fact that React Native looks fundamentally the same as React.js, there are sure contrasts in their utilization and structure. Right now, we will talk about and see what separates React Native from React.js.

React.js

React.js is essentially a JavaScript library worked to make easy to understand and responsive UI parts. And furthermore known as React, the library is liable for the rendering of UI segments in an ordinary specialized sense. It is fit for supporting both frontend and server-side tasks.

React Native

React Native is an incredible JavaScript structure used to assemble local applications, as it orders to React to Native parts. Like React JS, and React Native likewise has the base deliberations of React DOM.

This proposes while parts are unique, their language structure and work process stay comparable.

Arrangement and Running Process

React.js is a JavaScript library that you can use for web improvement. While firing another undertaking and setting up ReactJS, you should pick Webpack, which is really a Components bundler. You will at that point choose which packaging modules will explicitly suit your undertaking.

In React Native, you have all that you have to set up and begin. It is so natural and quick to dispatch the system. Everything necessary is to run one order in your terminal, and you are prepared to begin coding your first historically speaking React Native application.

Movements Used In React

Dissimilar to React JS, where CSS assists with making liveliness, React Native causes you to adapt completely better approaches to utilize JavaScript and make activities for parts of your application.

With React Native, designers can energize parts in the application by utilizing the Animated API. There is a serious notable JavaScript library, Velocity.js, that you can use too.

Velocity.js permits engineers to frame arranged liveliness. They work dependent on the schedule and speed of the signal and can be utilized in numerous mixes. You can likewise utilize LayoutAnimation to React Native that is gainful for making advances, particularly on iOS.

Engineer Tools

Quick application advancement searchers would be glad to utilize React in their local task since you as of now get a couple of extraordinary apparatuses without really introducing anything.

This one of a kind quality spares a ton of time and exertion for designers. What's more, hot reloading empowered by React JS proves to be useful when there is a need to roll out little improvements to generally speaking application styles.

You can use Live Reload if there are greater chances to add to the application rationale so that your application reloads after changing the code.

Respond Native designers can utilize numerous engineer apparatuses present in React JS. You can utilize Chrome Dev Tools to assess the system demands, handle logs, and investigate applications.

You likewise have Redux DevTools for additional help with an examination. In any case, the local examiner isn't useful since you can't review DOM with React Native as you can do on the web.

Business Benefits of React.js

Respond's DOM (record object model) that oversees information sources of info and yields is a lot quicker than the traditional invigorate model. Since it just in part invigorates certain pieces of the page, Facebook never knew the way toward reviving would end up being quicker. By emphatically influencing the re-fabricate time, the fractional DOM invigorate in the long run helps execution and speed while composing programs.

The marvel of reusable code segments in React JS further spares you a great deal of time.

React.js likewise improves the troubleshooting speed, which exceptionally favors designers' work.

The chance of rendering pages from the server to the program helps decidedly with SEO.

Respond effectively comes to even amateurs. Since it is easily coherent, in contrast to different structures, React doesn't expect you to turn out to be vigorously familiar with a broad rundown of ideas.

Since it depends on JavaScript, designers are allowed to receive the most extreme rewards of all the advancement and updates in the Java environment.
