In this article, you will find a concise step by step guide on how to setup 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 my personal recommendations for such a setup. 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
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 nvm. 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 Visual Studio Code 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 iterm2) 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 create-react-app:
npm install -g create-react-app
This package allows you to bootstrap React applications with zero-configuration. There is no need to get involved too early in toolings with Webpack and Babel. If you are going to read “The Road to learn React” to learn React, you will use create-react-app as well. It’s the simplest approach to learn plain React without worrying about all the tooling with Webpack and Babel around it. After installing it, you can check its version again on the command line:
create-react-app --version *v1.5.1
Finally, you can bootstrap your first React.js application on MacOS. You can use create-react-app by passing the name of your application to it on the command line:
Afterward, you can navigate into the project on the command line and start it with npm:
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.
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 their official website. GitHub is a social platform where you can follow other people (you could have your first social interaction with me), 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 git website. However, I recommend it via Homebrew. If you want to follow this recommendation, checkout the Homebrew and Git/Github sections over here. 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 this essential guide on how to use git and GitHub.
React with Prettier for Visual Studio Code
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:
That’s everything you need for a React development setup in MacOS. I hope you have everything to get started in React on your machine. Let me know what other tools you are using on MacOS in the comments below. Otherwise, if you are curios about the tools that I am using on my machine, head over to my personal development setup guide.
