In this article, you will find a concise step by step guide on how to install React on MacOS. It follows the philosophy of having one IDE to manage most of your web development tasks. That’s how you can focus on your task at hand as a developer. However, if you like to compose your development environment with lightweight tools rather than with an full-blown IDE, checkout. Nevertheless, if you just want to find a way for getting started with React on Mac OS quickly, follow the guide below. Node.js and NPM on MacOS Since you are going to use JavaScript for your React development on MacOS, there is no way around Node.js and NPM. Node.js is a JavaScript runtime which makes it possible to run JavaScript outside of the browser.
The underlying node package manager (NPM) is used to install frameworks and libraries, such as React.js, to your project on the command line. They are called node packages.
You will see later on how this works out on the command line for MacOS users installing libraries for React. In order to install and manage Node.js on your MacOS machine, you can install it from their official website. However, I encourage you to checkout. It’s a node version manager that allows you to manage multiple node versions, to upgrade and downgrade node versions and to be flexible in choosing a node version for your project at hand.
You can find the installation instructions in the GitHub repository. Installing node will install npm (node package manager) as well. The node package manager is used to install libraries/frameworks (node packages), such as React, on the command line to your project. Visual Studio Code for React on MacOS There are plenty of editors and IDEs out there to develop web applications. Depending on your personal, project or company requirements, you can choose from a range of lightweight editors to full-blown IDEs. Visual Studio Code is a solution in between.
Many developers, operating on MacOS but also Windows, enjoy using it. That’s why my recommendation would be Visual Studio Code to start developing React applications on MacOS. The installation on a MacOS machine is simple: Navigate to the official website and download the recent version of VS Code. Afterward, install it and check if everything is working when you open it. That’s it for the installation of an editor/IDE on your machine.
If you want to use another editor/IDE, it is up to you. But keep in mind that a couple of the following steps are building up on top of Visual Studio Code. However, it should be possible to substitute these steps for your own editor/IDE. NPM on the Command Line for create-react-app If you are just getting started with web development, you should create a dedicated folder on your machine to manage all your web development projects. It’s up to you to divide the folder into subfolders. For instance, there could be a folder for React applications and another one for plain Node.js applications.
Once you have your folder for your projects, open this folder in Visual Studio Code. In Visual Studio Code you should be able to open a tab which is called “Terminal” at the bottom. That’s your integrated command line in Visual Studio Code to install node packages with NPM or to start/test your project. It’s up to you to use the integrated terminal or another command line interface (e.g. The built-in command line or something like ) for your MacOS machine. Now, you should check whether the Node.js installation for MacOS was successful.
On the command line, type the following commands. They should output the versions for Node.js and NPM. The following versions may vary from your versions. Node - version. v8. 9.4 npm - version.
v5. 6.0 Now you can install your first node package with npm on the command line.
You will install it globally with a -g flag. Because of installing it globally, you will always have access to it on the command line.
Later on, when you install a node package for your project without the -g flag, you will only have access to the node package (node module) in your project. On the command line (in Visual Studio Code), type the following command to install.
Cd my - app npm start The command line should give you an output where you can find the application in the browser. The default should be localhost:8080.

If you are only using Safari on your MacOS machine, I can recommend you to install Chrome as well to access the developer environment and the React Developer Tools which are available as Chrome extension. If you just want to learn React now, you could start to read. It’s a pragmatic book which guides you step by step through building a React application from scratch. Along the way, you will transition from JavaScript ES5 to JavaScript ES6 and you will lots of exercises to improve your React skills. Git for Visual Studio Code and MacOS At some point, you might want to share your projects on GitHub or collaborate with other people via the git version control.
If you want to use GitHub as your platform of choice, you should create an account via. GitHub is a social platform where you can follow other people , like (star) their projects or collaborate on open source projects with other people.
In order to have git available on the command line and in Visual Studio Code, you need to install it. You can find all the instructions on the official. However, I recommend it via Homebrew. If you want to follow this recommendation, checkout. After installing it, you should have it available on the command line. Git - version.
git version 2.15. 1 If it doesn’t show up in Visual Studio Code, you may have to restart the application. Afterward, you should see that Visual Studio Code already comes with a git integration as well.
It’s convenient to use git from this integration, but you can also use it from the command line now. That’s it for the git installation and the account creation on GitHub. Furthermore, you can check out. React with Prettier for Visual Studio Code There is one optional step to make your experience as a developer more pleasant. You can install directly in Visual Studio Code. Prettier is an opinionated code formatter for JavaScript.
Often you will worry about your code style when implementing your web applications. In addition, it’s always difficult to follow one code style as a team in a company. That’s why it is convenient to use Prettier as automatic code formatter. Once you have installed it, you can use it with CTRL + CMD + P to format a file. You should have an opened file to perform it. If you don’t want to format your file manually every time, you can perform it on saving the file as well.
Therefore you need to open your Visual Studio Code user settings/preferences and put in the following configuration.
Update note: This tutorial has been updated to React Native 0.50, Xcode 9, and iOS 11 by Christine Abernathy. The previous tutorial was written by iOS Team member Tom Elliot. In this React Native tutorial you’ll learn how to build native apps based on the hugely popular JavaScript library. What makes React Native different from other frameworks such as or, that use JavaScript to create iOS apps?.
(Unlike PhoneGap) with React Native your code may be written in JavaScript but the app’s UI is fully native. It doesn’t have the drawbacks typically associated with a hybrid HTML5 app. Additionally (unlike Titanium), React introduces a novel, radical and highly functional approach to constructing user interfaces. Your UI is simply a function of the current app state.
React Native brings the paradigm to mobile app development. It’s goal isn’t to write the code once and run it on any platform. The goal is to learn-once (the React way) and write-anywhere.
An important distinction to make. This tutorial only covers iOS, but once you’ve learned the concepts here you could port that knowledge into creating an Android app very quickly. If you have only ever written applications in Swift, you might not be particularly excited about the prospect of using JavaScript.
However, the functional programming aspect should pique your interest! Swift has introduced more functional ways to encode algorithms, as well as techniques that encourage transformation and immutability. However, the way in which you construct your UI is very much the same as it was when developing with Objective-C: it’s still UIKit-based and imperative.

The community has even added tools such as and to help you quickly build React Native apps without having to touch Xcode or Android Studio! This React Native tutorial takes you through the process of building an iOS app for searching UK property listings: Don’t worry if you’ve never written any JavaScript or used the CSS-like properties you’ll see. This tutorial will guide you through every step and provide resources where you can learn more.
Ready to get going? Note: We also have an that you may be interested in. Getting Started React Native uses, a JavaScript runtime, to build your JavaScript code.
Dresses ieena for mac. If you don’t already have Node.js installed, it’s time to get it! First install Homebrew using the instructions on the. Then install Node.js by executing the following in a Terminal window: brew install node Next, use homebrew to install, a file watcher from Facebook: brew install watchman This is used by React Native to figure out when your code changes and rebuild accordingly. It’s like having Xcode do a build each time you save your file. Next use npm to install the React Native Command Line Interface (CLI) tool: npm install -g react-native-cli This uses the to fetch the CLI tool and install it globally; npm is similar in function to or and is packaged with Node.js. Navigate to the folder where you would like to develop your app and run the following in Terminal: react-native init PropertyFinder This uses the CLI tool to create a starter project containing everything you need to build and run a React Native app.
If you get complaints about the version of node, make sure the one installed by brew is the one in use. Run brew link -overwrite node in the terminal. In Terminal, run: cd PropertyFinder In the created folders and files you will find a few items of note:. nodemodules is a folder which contains the React Native framework. index.js is the entry point created by the CLI tool. App.js is the skeletal app created by the CLI tool.
ios is a folder containing an Xcode project and the code required to bootstrap your application. android is a folder containing Android-related code, you won’t be touching those in this tutorial.
Open the PropertyFinder.xcodeproj in the ios folder with Xcode, then build and run. The simulator will start and display the following. If you encounter a compiler error indicating 'config.h' file not found in the third-party target, you may need to install Glog manually. If you see build-time warnings related to updating PropertyFinder project settings, go ahead and make those updates. Ignore warnings related to the other projects. Many of the warnings may be related to unused parameters. You may also see null pointer logic errors in the yoga library that are actually not errors.
You might also have noticed that a terminal window has popped up, displaying the following: This is, the React Native JavaScript bundler running under Node.js. You’ll find out what it does shortly. Before opening the finished project or the challenge solution, first run npm install via the Terminal in the root folder of the project. Check out the if you’re curious. I suggest taking a look at this to continue brushing up on modern JavaScript. If you’re a web developer, you’ve seen how to use JavaScript to easily create a native app. If you’re a native app developer, you’ve gained some appreciation for React Native’s fast iteration cycle.
Whether you decide to use React Native in a future app or simply stick with Swift, I hope you’ve learned some interesting principles to apply to your next project. If you have any questions or comments on this React Native tutorial, feel free to join the discussion in the forums below!
