React.js was developed by Facebook to address its need for a dynamic and high performing User Interface(UI). In 2011, Jordan Walke and his team from Facebook released the React JS library, a JavaScript library which brought together the speed of JavaScript and a new way of rendering pages, leading to a responsive and dynamic user input. In 2015, two years after the team open sourced React.js and its popularity grew, they released React Native.

Below is an overview of the business advantages of working with both React.js and React Native. It should give you a fair idea of their respective strengths and what makes them different.

React.js

React.js often referred to as React or ReactJS is a JavaScript library responsible for building a hierarchy of UI components or in other words, responsible for the rendering of UI components. It provides support for both frontend and server-side.

Remember, React.js is just the V part of the MVC framework, a library meant for rendering your views.

Business advantages while working with React:

  • DOM (document object model) is a viewing agreement on data inputs and outputs. React’s virtual DOM is faster than the conventional full refresh model, since the virtual DOM refreshes only parts of the page. The interesting part is, the team at Facebook wasn’t aware that partially refreshing a page would prove faster. Facebook was just looking for a way to reduce their re-build time, and partial DOM refresh was just a happy consequence. This increases performance and faster programming.
  • You can reuse code components in React JS, saving you a lot of time.
  • The rendering of your pages completely, from the server to the browser will improve the SEO of your web app.
  • It improves the debugging speed making your developer’s life easier.
  • Even to those unfamiliar with React, it is easily readable.Many frameworks require you to learn an extensive list of concepts which are only useful within the framework. React strives to do the opposite.
  • You reap the benefit of all the advancements in the JavaScript language and its ecosystem.
React Native

React Native is a framework for building native applications using JavaScript. React Native compiles to native app components, which makes it possible for you to build native mobile applications. In React JS, React is the base abstraction of React DOM for the web platform, while with React Native, React is still the base abstraction but of React Native. So the syntax and workflow remain similar, but the components are different.

Business advantages of using React Native:

  • React Native comes with Native Modules and Native components that improve performance. Unlike Cordova, PhoneGap, and other cross-platform frameworks that render code via WebView, React Native renders certain code components with native API’s.
  • React Native comes with all the advantages that React.js brought you. React.js focuses on a better UI, so those benefits remain.
  • You don’t have to build the same application for iOS and Android, separately as React Native allows your developers to reuse the common logic layer.
  • React Native’s component-based structure allows developers to build apps with a more agile, web-style approach to development than most hybrid frameworks, and without any web at all.
  • If you know JavaScript, React Native will be easy to pick-up, allowing most front-end web developer to be a mobile developer. All you need to know is JavaScript, platform APIs, some native UI elements, and any other platform-specific design patterns and you’re set.
  • No need to overhaul your old app. All you have to do is add React Native UI components into your existing app’s code, without having to rewrite.
  • Native app development usually means inefficiency, slower time to deployment, and less developer productivity. React Native is all about bringing high speed, responsiveness, and agility of web app development along with effectual processing and best user experience to the hybrid space, to provide your users with a native app experience.

Conclusion (TL;DR)

React is a framework for building applications using JavaScript. React Native is an entire platform allowing you to build native, cross-platform mobile apps, and React.js is a JavaScript library you use for constructing a high performing UI layer. React.js is the heart of React Native, and it embodies all React’s principles and syntax, so the learning curve is easy.

The platform is what gave rise to their technical differences. Like the browser code in React is rendered through Virtual DOM while React Native uses Native API’s to render components on mobile. React uses HTML and with React Native, you need to familiarize yourself with React Native syntax.

React Native doesn’t use CSS either. This means you’ll have to use the animated API which comes with React Native to animate different components of your application.

Bottom line, React is ideal for building dynamic, high performing, responsive UI for your web interfaces, while React Native is meant to give your mobile apps a truly native feel.

React, Angular, Vue, Ember, Backbone, Stencil, Preact…. in fact there’s probably another one being released right now. Microfrontends — bringing JavaScript frameworks together (React, Angular, Vue etc)

Like most things in life, a variety of choices informs a toxic culture of mine is better than yours and you’re wrong and I’m right.

Since technology advancements have got us in this mess, is there any chance it could get us out of it as well?

Enter Microfrontends…

Introduction to Microfrontends

Modern UI development regardless of your framework has became all about component composition: You adapt to a framework’s way of doing things by following their patterns and conventions to create components usually underpinned by some sort of data model usually in the form of a service or state object.

For example: Angular has a strong opinion on how everything should be architected in the frontend. React although it only deals with components has a huge ecosystem backing it driven by a community of React-centric developers.

**Microfrontends **have gathered huge momentum recently as away of allowing multiple teams to work on a single UI using multiple frameworks, but could it really change the landscape of UI development?

In this article, I am going to spend some time looking at the SDLC (software development lifecycle) and the advantages of adopting such an architecture.

Where’s the problem?

The current trend in UI development, is to build a feature-rich and powerful browser application (single page application) using a chosen framework.

Development results in building lots of little components which are then bundled together in some sort of build process using something like webpack or rollup.

Over time the UI layer often developed by separate or multiple teams, grows and gets more difficult to maintain creating a huge monolithic frontend.

Monolithic frontend SDLC

Monolithic frontends deployment architecture

Reversing the microservice anti-pattern:

Microfrontends looks at removing that monolithic build step, and results in completely decoupled services that can be independently built and deployed:

Microfrontend SDLC

Microfrontend deployment architecture

Now our UI architecture has all the qualities of traditional microservices:

  • Highly maintainable and testable
  • Loosely coupled
  • Independently deployable
  • Organised around business capabilities
How could this bring the big frameworks together?

Since we have decoupled our UI components into many microfrontends, we no longer have to dictate which framework each component uses.

The below illustration shows how we could potentially have different application teams using different technologies to create their independently built and released microfrontend:

SDLC using multiple frameworks

There are **several ways **to solve this using technologies but let me illustrate one example:

  1. **Develop: **Three teams using a different JavaScript framework for each microfrontend
  2. Build: Wrapping their microfrontend components as web components*** ***and building their project as a JavaScript file
  3. Release: A single JavaScript file is released inside a docker container served using Ngnix

Once we have released our microfrontends, we should compose them together in a single UI layer. The communication between the microfrontends should be handled by the composition layer which should have a well defined contract.

Deployment architecture using multiple frameworks

From a user perspective they access a single application, but the developer’s ability to solve a problem is no longer limited by what single framework the application uses.

Build a Basic CRUD App with Vue.js and Node

React Slideshow Framework – react-presents

React Slideshow Framework – react-presents

React Slideshow Framework – react-presents

Getting started

Install react-presents using npm.

source-shell
npm install react-presents --save

ES6, CommonJS, and UMD builds are available with each distribution. For example:

source-js
// Import the components you want like so:
import { Presentation, Slide } from 'react-presents'

Alternately you can load a global-friendly UMD build which exposes a global ReactPresents object:

text-html-basic
<script src="path/to/react-presents/dist/umd/react-presents.js"></script>

Now you're ready to start using the components.

For an example of a the kind of presentations that can be created with react-presents, check out my Connect Tech 2016 presentation on windowing with React: bvaughn.github.io/connect-tech-2016.

Example Usage

Creating a Slide

Presentation slides are simple to create. You can use TitleSlide and ContentSlide with some predefined styles, or simply create a slide with custom layout by wrapping its content in div with 100% height and width. Below is a couple of example slides:

source-js-jsx
/* SomeSlide.js */
import React from 'react'
import { ContentSlide, Step } from 'react-presents'

export default () => (
  <ContentSlide>
    <h1>A simple slide</h1>
    <p>Slides can contain multiple steps.</p>
    <ul>
      <Step index={1} exact><li>Sub-text can appear only for a specific step</li></Step>
      <Step index={2}><li>Or it can be additive</li></Step>
      <Step index={3}><li>(By default it is additive)</li></Step>
      <Step index={4} maxIndex={5}><li>They can also be shown for a range</li></Step>
    </ul>
  </ContentSlide>
)

Automatically Loading Slides

Using a bundler like Webpack, you can auto-load slides using an approach like follows:

Webpack 2
source-js-jsx
/* Application.js */
const slides = require.context('./path/to/slides/', false, /\.js$/)
  .keys()
  .map((filename) => filename.replace('./', './path/to/slides/'))
  .map((path) => require(path).default)
Webpack 3
source-js-jsx
/* Application.js */
const slides = []
const context = require.context('./path/to/slides/', false, /\.js$/)
context
  .keys()
  .forEach(key => slides.push(context(key).default))

Creating a Nav Menu

Once you have an array of loaded slides, you can auto-populate the options for a nav menu using an approach like so:

source-js-jsx
/* Application.js */
const options = slides
  .map((slide, index) => ({
    label: slide.title,
    value: index
  }))
  .filter((option) => option.label)

Note that the above approach assumes that slides have a static title attribute, eg:

source-js-jsx
/* SomeSlide.js */
import React from 'react'
import { ContentSlide } from 'react-presents'

const slide = () => (
  <ContentSlide>
    <h1>{slide.title}</h1>
    {/* Your content goes here */}
  </ContentSlide>
)

slide.title = 'The first slide'

export default slide

Also note that react-select is used beneath the hood so the options array you construct must be compatible with it.

Creating a presentation

Assuming you have an array of slides and options for the drop-down nav, you can create a presentation like follows:

source-js-jsx
import React from 'react'
import { Presentation, Slide, DropDownNav } from 'react-presents'

export default () => (
  <Presentation>
    {slides.map((Component, index) => (
      <Slide
        component={Component}
        key={index}
      />
    )).concat(
      <DropDownNav
        key='DropDownNav'
        options={options}
      />
    )}
  </Presentation>
)

A default theme is provided with react-presents. You can disable this theme by specifying the disableTheme property:

source-js-jsx
<Presentation disableTheme>
  {slides}
</Presentation>
