- As stated already, the most compelling feature of React is that it reduces the complexities of user interface.
- You describe the user interfaces in React languages and tell it what you want, it will take care to translate your description and prepare the actual interface.
- You will illustrate user interfaces to React with simple components.
- When state of a component changes, its User Interface will change automatically.

- ReactJS focuses only on the rendering of View (part of MVC), as it does not implement the entire MVC pattern, but tightly focuses on the development of components (views) which are displayed on the user-interface so that it is more efficient in developing dynamic and interactive user-interfaces and its components….
- Traditionally, when we used to change the data (model in MVC) at server-side, we used to reload the entire page (at client-side) to implement or reflect the updates from the server, which make processing very slow and creates bad user-experiences.
- But ReactJS has solved these issues as it works at the client-side and takes care of the updates from the server by just changing those particular components or parts of interfaces which are changed, and it does not reload the entire page.
- DOM (Document Object Model) is the user-interface or HTML document which is rendered or displayed on the screen, and if we have to rerender the entire DOM every time to reflect the changes that come from the server, it would be very expensive and take many CPU-cycles and processor time….
- To overcome these issues, ReactJS creates Virtual DOMs in memory and whenever any data is changed at the server, ReactJS rewrites the Virtual DOM, and then it performs “diff” operations between all Virtual DOMs… one which was created initially and the other which is created after the change of data….

- While React simplifies the challenge of making API calls, figuring out how best to structure your application around an API is more difficult.
- There are two primary approaches: using the React built-in fetch methods, or using axios, a promise-based library.
- Instructor Emmanuel Henri covers the basic concepts behind REST APIs and shows how to build reusable components that use fetch methods to call real-world APIs like News API.
- He then shows how to connect to APIs using axios, which simplifies API calls by automatically transforming JSON data.
- By the end of the course, you should have the skills to structure API calls, maintain state, and make users happy.

- But then I saw that the React team was working on framework called React Native that would work on both iOS & Android (despite the Android version coming out much later)…GAMECHANGER.
- Neither the React Native code for iOS or Android was available yet but just the fact that a large team like the Facebook Dev group was working on a solution like this got me excited enough to start all my new web projects in React.
- I just mention Live Reload first because when switching between React Native and Swift and/or Java…or Objective-C, it is the first thing you notice in speed of development.
- While you certainly won’t just be copying the same code you wrote from the web application and pasting it into the iOS and Android version expecting it to work, there are a lot of reusable modules between platforms.

- A few months ago, I wrote about our adventures building a brand new project using React.
- Our existing SparkPost app was built many moons ago in the ancient framework known as AngularJS.
- Shortly after that article was published, I started in on my plan to improve the Angular app.
- Ultimately we realized that the fastest and safest way to rebuild our entire app in a brand new framework was to do exactly what I’d publicly ridiculed: direct migration, i.e. a parallel rebuild.
- Step 2: Draw the rest of the [censored] owl.
Sometimes even the best-laid plans need to be re-laid. A walk through on how (and why) we’re migrating our Angular app directly to React.

- Our React Native GL library is inÂ alphaBy: Nick ItalianoWeâre officially supporting React Native Mapbox GL.
- Our mobile team has started a rewrite of our current experimental React Native library and released an alpha đUsing the React Native framework, developers can build cross-platform mobile applications in half the time.
- Our React Native library will make it as efficient as possible to access our APIs and open source libraries, so you can focus on shipping features.Reusable components are the strongest aspect of React, which is why weâve created expressive and easy to use components for powerful features like runtime styling…
- With this in mind, you can render a custom styled map centered on San Francisco in just 25 lines of code.First look runtime styling in ReactÂ NativeRuntime styling is the first major feature with added support in this alpha release.
- Here is a preview of a couple examples you can find in our sample application.3D buildingsMarker clusteringWhatâs nextWe plan on bringing our React Native SDK to feature parity with our Android/iOS SDKs and want to be active in the community:We have a Gitter channel where you can post any questions…

- Share Code between React and React Native AppsDevelopers are adopting Higher Order Components (HOC) Stateless Functional Components, and for good reason: they make it easier to achieve code reuse, a coveted aspiration of developers.There are many articles on HOC and Functional Stateless Components.
- But here are a few benefits to consider:UX consistency, both within an application and across devicesMake cross-cutting upgrades: improve a component and update all its uses easilyreuse routing and authorization rulesSwitch libraries (for example, the apps below uses MobX for state management, but Redux could be swapped in)I’ll focus on using HOC and Functional Stateless Components to achieve reuse.
- It will not use routes nor multiple scenes as the focus is on component reuse.We will add a second pair of applications (React and React Native), which will reuse the components we extract.This GitHub repo branch has the baseline applications (The final result is here.)
- You have to “see” the duplication, which might require rearranging code blocks.Applying these ideas is like moving puzzle pieces around, to find where they meet and what patterns they reveal.Let’s start by looking for duplication.Seeing DuplicationThe web and mobile applications have two main components.In the web application, App.jsIn the mobile application, SearchView.jsThe following outlines their structure.Almost the same, but the platform differences between React and React Native are in the way.The two components have similar structures.
- But they are in the README for the GitHub repo branch.Instead, I’ll focus on the refactoring to a common SearchBox, which our web (React) and mobile (React Native) applications will both use.Extracting a Shared Component for Web and MobileFor clarity, I’ve renamed SearchInput.js, SearchResults.js and SearchBox.js to WebSearchInput.js, WebSearchResults.js and WebSearchBox.js, respectively.Let’s look at (Web)SearchBox.jsLines 2–10, 19, 20, 26, 27 are specific to React.MuiThemeProvider, a container for Material UI components, is the only direct dependency on Material UI.
