Welcome readers! Have you been thinking of switching to Node.js for your web development needs? If the answer is yes, then you must also think of installing Nvm on your Mac. Nvm stands for Node Version Manager and as the name suggests, it allows you to manage multiple versions of Node.js on a single machine. In this article, we will guide you on how to install Nvm on your Mac in easy and simple steps. We will start with the basics, so even if you are a newbie, you can follow along.
Steps
Step 1: Installing Homebrew and Xcode
Before we begin with installing Nvm, we need to install two dependencies- Homebrew and Xcode. Homebrew is a package manager for Mac OS X and Xcode is Apple’s Integrated Development Environment (IDE).
To install Homebrew, open the terminal, and type the following command:
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install.sh)"
After Homebrew is installed, type:
xcode-select --install
This will install Xcode.
Step 2: Installing Nvm
Now that we have installed the dependencies, we can move on to installing Nvm. To install Nvm using Homebrew, type the following command in your terminal:
brew install nvm
Step 3: Configuring Nvm
After installing Nvm, we need to configure it to work with our system. Type the following command in the terminal:
nano ~/.bash_profile
This opens the bash profile in the nano editor. Add the following command at the end of the file:
export NVM_DIR="$HOME/.nvm"
After adding the above command, save and exit the nano editor by pressing the Ctrl+X keys and then Y and Enter.
Step 4: Sourcing Bash Profile
After adding the above command, we need to source the bash profile again for the changes to take effect. Type:
source ~/.bash_profile
Step 5: Testing Nvm
To test if Nvm is installed properly, type the following command in the terminal:
nvm --version
If you get a version number, then Nvm installed successfully.
Step 6: Installing Node.js
Now it’s time to install Node.js using Nvm. Type the following command:
nvm install node
This command installs the latest version of Node.js.
Step 7: Using a Specific Node.js Version with Nvm
Nvm allows you to use multiple versions of Node.js on your machine. To use a specific version of Node.js, type the following command:
nvm use node_version_number
For example:
nvm use v14.17.0
Step 8: Setting Default Node.js Version with Nvm
If you want to set a default Node.js version, type the following command:
nvm alias default node_version_number
For example:
nvm alias default v14.17.0
Step 9: Listing All Installed Node.js Versions
To list all the Node.js versions installed on your machine, type the following command:
nvm ls
This will list all the installed Node.js versions.
Step 10: Uninstalling a Node.js Version with Nvm
If you want to uninstall a specific version of Node.js, type the following command:
nvm uninstall node_version_number
For example:
nvm uninstall v12.16.1
Step 11: Upgrading Nvm
To upgrade Nvm to the latest version, type:
brew upgrade nvm
Step 12: Updating Npm
To update npm (the Node Package Manager), type the following command:
npm install -g npm
This will install the latest version of npm.
Explanation
Now that we have covered all the steps of installing Nvm on your Mac, let’s dive deeper into understanding what Nvm is and why it is important.
Nvm (Node Version Manager) is a tool that allows you to manage multiple versions of Node.js on your machine. This means that you can have different versions of Node.js installed on your Mac and switch between them based on the project you are working on. This is extremely useful as different projects may require different versions of Node.js and using Nvm saves you the trouble of uninstalling and reinstalling different versions of Node.js.
One of the benefits of using Nvm is that it allows you to test your application on multiple versions of Node.js. This helps ensure that your application works on all versions of Node.js and avoids any compatibility issues that may arise in the future.
Another benefit of using Nvm is that it allows you to maintain consistency across your team. If your team is working on multiple projects, with different versions of Node.js, using Nvm ensures that everyone is on the same page and working with the same version of Node.js.
Tips and Tricks
Now that you know how to install and use Nvm on your Mac let’s look at some tips and tricks to make your experience with Node.js even better.
Tip 1: Keep Nvm Updated
Make sure to keep Nvm updated to ensure that you have access to all the latest features and bug fixes.
Tip 2: Use Npm to Manage Packages
Npm is the default package manager for Node.js and can be used to manage all your project’s dependencies.
Tip 3: Backup Your .bash_profile File
Your .bash_profile file contains all the configurations for Nvm. Make sure to back it up regularly to avoid losing any data.
Tip 4: Use .nvmrc Files
.nvmrc files allow you to specify which version of Node.js to use for a particular project. This can be really helpful if you have multiple projects with different versions of Node.js.
Tip 5: Use the –lts Flag
The –lts flag installs the long-term support version of Node.js. This version is more stable and preferred for production environments.
Tip 6: Check Compatibility of Node.js with Your OS
Make sure to check the compatibility of the Node.js version you want to install with your operating system.
Tip 7: Avoid Installing Multiple Versions of Node.js if You Don’t Need Them
It’s always better to keep your machine clean and avoid cluttering it with unnecessary versions of Node.js.
Tip 8: Use Npm Scripts
Npm scripts allow you to automate tasks and make your workflow more efficient.
Tip 9: Use Node.js Version Managers for Different Operating Systems
There are different version managers available for Node.js depending on your operating system. Make sure to choose the appropriate one for your OS.
Tip 10: Keep Your Dependencies Updated
Make sure to keep all your project’s dependencies updated to avoid any security vulnerabilities and ensure that your application runs smoothly.
That’s it for this article. We hope you found it helpful and informative. Now go ahead and install Nvm on your Mac and enjoy all the benefits of managing multiple versions of Node.js.
