Introduction to Nodemon for Linux Bash: Streamlining Node.js Development

When engaging in Node.js development, one of the small annoyances is having to restart the server manually every time you make changes to your code. Thankfully, there’s a utility that can automate this process: Nodemon. This tool monitors the files in your directory for any changes and automatically restarts your server, making development faster and more efficient. This blog will guide you on how to set up Nodemon in a Linux environment and will include installation instructions for various package managers such as apt, dnf, and zypper.

What is Nodemon?

Nodemon is a utility that wraps your Node.js application, watching file changes in your directory and automatically restarting the process. It's a CLI tool, hence it requires a terminal (or a command prompt) and some familiarity with basic command line operations. It is incredibly useful in development by saving time and reducing manual intervention.

Installation of Nodemon

Before installing Nodemon, ensure you have Node.js and npm (Node Package Manager) installed. Nodemon is installed globally using npm, making it available from any directory in your terminal.

General Installation via npm

For all Linux distributions, the most straightforward method to install Nodemon is via npm. Open your terminal and enter the following command:

npm install -g nodemon

Specific Installation Instructions per Package Manager

Although installing via npm is straightforward, some developers might prefer using their native package manager. Here’s how you can install Nodemon using different package managers on various Linux distributions:

For Ubuntu/Debian systems using apt:

As of the latest updates, Nodemon isn't directly available via apt. It's recommended to use npm for installing Nodemon. If you still prefer using apt, ensure you have npm installed first (as you'll need it regardless), then proceed with npm install -g nodemon.

For Fedora systems using dnf:

Like Debian/Ubuntu, Fedora also does not have Nodemon directly available via dnf. You'll have to install Node.js and npm first. You can install Node.js and npm on Fedora like so:

sudo dnf module install nodejs

And then install Nodemon globally using npm:

npm install -g nodemon

For openSUSE systems using zypper:

OpenSUSE does not offer Nodemon directly through zypper. First, install Node.js and npm with:

sudo zypper install nodejs npm

Then, use npm to install Nodemon globally:

npm install -g nodemon

Using Nodemon

After installation, you can start using Nodemon immediately. To run your application with Nodemon, replace the node command with nodemon in your terminal. For example:

nodemon app.js

This will start your Node.js application with Nodemon, and it will restart automatically whenever file changes in the directory are detected.

Conclusion

Nodemon is an invaluable tool for Node.js developers aiming to enhance efficiency in their development process. By automatically restarting your server every time you make changes to your code, it cuts down significantly on development time and helps streamline the testing and refinement phase of developing Node.js applications.

For Linux users, while direct installation through some native package managers like apt, dnf, and zypper isn't always available, npm provides a universal method to get Nodemon up and running regardless of your distribution. Enjoy your coding, and revel in the productivity boosts Nodemon brings to your Node.js projects!
