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 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
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 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.
Node and NPM for React
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. Video gif creator 1 2 release. 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.
create-react-app for React on MacOS
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. Now, on the command line (in Visual Studio Code), type the following command to install create-react-app:
create-react-app 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 React', you will use create-react-app as well. It's the simplest approach to learn React without worrying about all the tooling around it. You can bootstrap your first React.js application with npx (which comes via npm) on MacOS with create-react-app by passing the name of your application to it on the command line:
Wired mouse for mac. Afterward, you can navigate into the project on the command line and start it with npm:
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 The Road to learn React. 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 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.
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.
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.
This tutorial is part 1 of 2 in this series.
- Part 2:How to use Prettier in VS Code
Node Js Ide Machine
Node.js is a platform for building fast and scalable server applications using JavaScript. Node.js is the runtime and npm is the Package Manager for Node.js modules.
Visual Studio Code has support for the JavaScript and TypeScript languages out-of-the-box as well as Node.js debugging. However, to run a Node.js application, you will need to install the Node.js runtime on your machine.
To get started in this walkthrough, install Node.js for your platform. The Node Package Manager is included in the Node.js distribution. You'll need to open a new terminal (command prompt) for the node
and npm
command-line tools to be on your PATH.
Linux: There are specific Node.js packages available for the various flavors of Linux. See Installing Node.js via package manager to find the Node.js package and installation instructions tailored to your version of Linux.

and you should see the usage documentation.
Hello World
Let's get started by creating the simplest Node.js application, 'Hello World'.
https://vtcyp.over-blog.com/2021/01/itools-pro-1-1-5-download-free.html. Create an empty folder called 'hello', navigate into and open VS Code:
Tip: You can open files or folders directly from the command line. The period '.' refers to the current folder, therefore VS Code will start and open the Hello
folder.
From the File Explorer toolbar, press the New File button:
and name the file app.js
:
By using the .js
file extension, VS Code interprets this file as JavaScript and will evaluate the contents with the JavaScript language service. Refer to the VS Code JavaScript language topic to learn more about JavaScript support.
Create a simple string variable in app.js
and send the contents of the string to the console:
Note that when you typed console.
IntelliSense on the console
object was automatically presented to you.
Also notice that VS Code knows that msg
is a string based on the initialization to 'Hello World'
. If you type msg.
you'll see IntelliSense showing all of the string functions available on msg
.
After experimenting with IntelliSense, revert any extra changes from the source code example above and save the file (⌘S (Windows, Linux Ctrl+S)).
Running Hello World
It's simple to run app.js
with Node.js. From a terminal, just type:
You should see 'Hello World' output to the terminal and then Node.js returns.
Integrated Terminal
VS Code has an integrated terminal which you can use to run shell commands. You can run Node.js directly from there and avoid switching out of VS Code while running command-line tools.
Descargar google home chromecast para pc. View > Terminal (⌃` (Windows, Linux Ctrl+`) with the backtick character) will open the integrated terminal and you can run node app.js
there:
For this walkthrough, you can use either an external terminal or the VS Code integrated terminal for running the command-line tools.
Debugging Hello World
As mentioned in the introduction, VS Code ships with a debugger for Node.js applications. Let's try debugging our simple Hello World application.
To set a breakpoint in app.js
, put the editor cursor on the first line and press F9 or click in the editor left gutter next to the line numbers. A red circle will appear in the gutter.
To start debugging, select the Run View in the Activity Bar:
You can now click Debug toolbar green arrow or press F5 to launch and debug 'Hello World'. Your breakpoint will be hit and you can view and step through the simple application. Notice that VS Code displays a different colored Status Bar to indicate it is in Debug mode and the DEBUG CONSOLE is displayed.
Now that you've seen VS Code in action with 'Hello World', the next section shows using VS Code with a full-stack Node.js web app.
Note: We're done with the 'Hello World' example so navigate out of that folder before you create an Express app. You can delete the 'Hello' folder if you wish as it is not required for the rest of the walkthrough.
An Express application
Node Js Ide Mac
Express is a very popular application framework for building and running Node.js applications. You can scaffold (create) a new Express application using the Express Generator tool. The Express Generator is shipped as an npm module and installed by using the npm command-line tool npm
.
Tip: To test that you've got npm
correctly installed on your computer, type npm --help
from a terminal and you should see the usage documentation.
Install the Express Generator by running the following from a terminal:
The -g
switch installs the Express Generator globally on your machine so you can run it from anywhere.
Permute 3 1 5 download free. We can now scaffold a new Express application called myExpressApp
by running:
This creates a new folder called myExpressApp
with the contents of your application. The --view pug
parameters tell the generator to use the pug template engine.
To install all of the application's dependencies (again shipped as npm modules), go to the new folder and execute npm install
:
At this point, we should test that our application runs. The generated Express application has a package.json
file which includes a start
script to run node ./bin/www
. This will start the Node.js application running.
From a terminal in the Express application folder, run:
The Node.js web server will start and you can browse to http://localhost:3000 to see the running application.
Great code editing
Close the browser and from a terminal in the myExpressApp
folder, stop the Node.js server by pressing CTRL+C.
Now launch VS Code:
Note: If you've been using the VS Code integrated terminal to install the Express generator and scaffold the app, you can open the myExpressApp
folder from your running VS Code instance with the File > Open Folder command.
The Node.js and Express documentation does a great job explaining how to build rich applications using the platform and framework. Visual Studio Code will make you more productive in developing these types of applications by providing great code editing and navigation experiences.
Open the file app.js
and hover over the Node.js global object __dirname
. Notice how VS Code understands that __dirname
is a string. Even more interesting, you can get full IntelliSense against the Node.js framework. For example, you can require http
and get full IntelliSense against the http
class as you type in Visual Studio Code.
VS Code uses TypeScript type declaration (typings) files (for example node.d.ts
) to provide metadata to VS Code about the JavaScript based frameworks you are consuming in your application. Type declaration files are written in TypeScript so they can express the data types of parameters and functions, allowing VS Code to provide a rich IntelliSense experience. Thanks to a feature called Automatic Type Acquisition
, you do not have to worry about downloading these type declaration files, VS Code will install them automatically for you.
You can also write code that references modules in other files. For example, in app.js
we require the ./routes/index
module, which exports an Express.Router
class. If you bring up IntelliSense on index
, you can see the shape of the Router
class.
Debug your Express app
You will need to create a debugger configuration file launch.json
for your Express application. Click on the Run icon in the Activity Bar and then the Configure gear icon at the top of the Run view to create a default launch.json
file. Select the Node.js environment by ensuring that the type
property in configurations
is set to 'node'
. When the file is first created, VS Code will look in package.json
for a start
script and will use that value as the program
(which in this case is '${workspaceFolder}binwww
) for the Launch Program configuration.
Save the new file and make sure Launch Program is selected in the configuration drop-down at the top of the Run view. Open app.js
and set a breakpoint near the top of the file where the Express app object is created by clicking in the gutter to the left of the line number. Press F5 to start debugging the application. VS Code will start the server in a new terminal and hit the breakpoint we set. From there you can inspect variables, create watches, and step through your code.
