Conclusion

Congratulations, you have successfully installed NVM on your macOS machine. You can now switch between different versions of Node.js using the simple commands provided by NVM. Happy coding!

Configuring NVM

NVM, or Node Version Manager, is a popular tool for managing multiple versions of Node.js on your machine. Here are the steps to configure it on your macOS:

1. Open your terminal and install NVM by running:

curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.0/install.sh | bash

2. After the installation, run:

~/.nvm/nvm.sh

3. Now, you can check if NVM is successfully installed by typing:

nvm --version

4. If the above command outputs a version number, you're good to go!

To install a specific version of Node.js using NVM, run:

nvm install [version]

For example, if you want to install version 14.17.6, run:

nvm install 14.17.6

You can switch between different versions of Node.js by running:

nvm use [version]

For example:

nvm use 14.17.6

And that's it! With NVM, you can easily manage multiple versions of Node.js on your machine and ensure compatibility with your projects.

Installing Node.js using NVM

If you're a developer who's been working with Node.js for a while, chances are you've encountered issues with package compatibility between different projects. In situations like this, installing multiple versions of Node.js on your machine can be a great solution, as it allows you to keep different projects separated and avoids potential conflicts between them.

One of the best tools for managing multiple versions of Node.js is NVM (Node Version Manager). NVM makes it easy to switch between different versions of Node.js and install new ones as needed, all from the command line.

To install NVM on your macOS computer, follow these easy steps:

1. Open the terminal app on your computer (you can find it in the Utilities folder of your Applications)

2. Enter this command to download the installation script:

   curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.35.3/install.sh | bash

   This will download the script and run it, installing NVM on your computer.

3. Once the script is completed, close and re-open your terminal.

4. To check if NVM installed successfully, enter the following command:

   nvm --version

   If you see the version number of NVM printed in the terminal, you're good to go!

5. To install a specific version of Node.js using NVM, enter the following command:

   nvm install <version>

   (replacing '' with the actual version number you want to install, such as '12.18.3')

6. To switch between different versions of Node.js, enter the following command:

   nvm use <version>

   (replacing '' with the version number you want to use)

That's it! With these simple steps, you can install and manage multiple versions of Node.js with NVM, saving you time and hassle in your development projects.

Installing Global Node.js Packages

Once you've successfully installed NVM to manage your Node.js versions, the next step is to start installing some global Node.js packages. These packages can be used across all of your projects and will save you time by providing commonly used tools and functionalities.

To install a global Node.js package, open your terminal and type the following command:

npm install -g <package-name>

Replace <package-name> with the name of the package you want to install. For example, if you want to install the popular development tool called "nodemon," you would type:

npm install -g nodemon

After running the command, wait for the installation to complete. Once done, you can start using the package in any of your Node.js projects. For example, if you've installed nodemon, you can use it to automatically restart your Node.js application whenever you make changes to your code:

nodemon server.js

This will start your server and automatically restart it whenever you make changes. No more manually stopping and restarting your server!

is a great way to streamline your development workflow and make coding easier and more efficient. Just remember to install only the packages that you need and use regularly. Installing too many packages can bloat your system and slow down your development process. Keep it lean and clean!
