Mac installation nodejs tutorial

If you are using a Mac computer for front-end development, then you must install Node.js. Node.js allows you to run JavaScript in your local development environment and is also great for automating tasks and packaging projects during development. Next, we will introduce you to how to install Node.js on Mac.

1. Installing Homebrew

Homebrew is a very popular Mac resource manager that can help you install and manage software packages. You can use the following command to install Homebrew:

/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"

2. Install Node.js

Before installing Node.js, we need to update Homebrew using the following command:

brew update

Next, we can use the following command to install Node.js:

brew install node

You may need to enter the administrator password during the installation process.

3. Verify whether the installation is successful

After the installation is completed, we can use the following command to verify whether Node.js has been successfully installed:

node -v

If the installation is successful , the version number of Node.js will be output.

4. Using Node.js

Now you can use Node.js in the terminal. Test with the following command:

node

This will turn on the interactive mode of Node.js. In this mode, you can enter JavaScript code and see the results immediately. For example:

> console.log("Hello, World!");
Hello, World!
undefined

We can see that "Hello, World!" is output, and undefined is also output on the console. This is because the console.log() method returns undefined.

5. Install global modules

If you need to use global modules from the command line, such as gulp or webpack, you need to install them. You can use the following command to install global modules:

npm install -g <module-name>

For example, to install global Gulp:

npm install -g gulp

You can use the Gulp command in the terminal.

Summary

Through the above steps, you can easily install and start using Node.js on your Mac computer. Node.js is very important in front-end development, allowing you to easily run JavaScript and automate some tasks.
