Nodemon is an essential utility for any Node.js developer because it monitors changes in the source code and automatically restarts the server. With Nodemon, the developer can focus on the development of the application without worrying about restarting the server manually. However, as Node.js evolves, the Nodemon version updates, and it may not be compatible with the current version of Node.js. Therefore, it is essential to check the nodemon version before using it. In this article, we will discuss how to check the nodemon version with code examples.
Why check nodemon version?
A common issue when developing Node.js applications, especially with Nodemon, is the compatibility between the node version and Nodemon version. Occasionally, new releases of Node.js contain breaking changes that can cause Nodemon to fail to execute. That is why it is essential to check the nodemon version before using it.
Checking the nodemon version
Checking the nodemon version is quite simple. We can do this by running a command on the terminal or by writing a JavaScript code. In this article, we will talk about two ways of checking the nodemon version.
Using the command line interface (CLI)
The simplest way to check the nodemon version is by using the CLI. Open the terminal and run the following command:
$ nodemon -v
This should output the current nodemon version installed on the system. The output will look something like this:
nodemon -v
2.0.7
As we can assume, this output indicates that the current nodemon version installed on our system is 2.0.7.
Using the JavaScript code
If we want to check the nodemon version programmatically, we can use a Node.js script and execute it. In the script, we can use the NPM module, nodemon. Here is an example code for checking the nodemon version using JavaScript:
const nodemon = require('nodemon');
console.log(nodemon.version);
Assuming that we have nodemon installed on our system, running this code will output the current nodemon version installed on the system. The output will look something like this:
2.0.7
Conclusion
As we have seen, checking the nodemon version is essential to ensure that it works smoothly with Node.js applications. We can do this either by using the command line interface or by writing a Node.js script. We hope the examples provided in this article will help you confirm the nodemon version installed on your system.

Nodemon
As mentioned in the article, Nodemon is a utility that automatically restarts Node.js applications when it detects changes in the source code. This feature is especially useful when developing Node.js applications because it saves the developer time and effort. By reloading the application automatically, the developer can focus on writing the code, rather than worrying about restarting the server manually.
Nodemon is an open-source package and can be installed using NPM (Node.js Package Manager). To install Nodemon, run the following command in the terminal:
npm install nodemon --save-dev
The --save-dev flag is used to add Nodemon as a development dependency in the package.json file.
After installation, we can run a Node.js application using Nodemon. Instead of running the application using the node command, we can run it using the nodemon command. Here is an example of how to run an application using Nodemon:
nodemon app.js
This command will start the application and monitor changes in the app.js file. If Nodemon detects any changes, it will automatically restart the server.
Node.js
Node.js is an open-source, cross-platform, back-end JavaScript runtime environment that allows developers to build scalable network applications using JavaScript. It uses an event-driven, non-blocking I/O model that makes it efficient and lightweight.
Node.js is built on top of Chrome's V8 JavaScript engine, which makes it fast and efficient. It also has a large ecosystem of modules and packages that can be installed using NPM.
To install Node.js, visit the official Node.js website and download the package for your operating system. Alternatively, you can also use a package manager like Homebrew (for Mac) or Chocolatey (for Windows) to install Node.js.
After installation, you can check the version of Node.js installed on your system using the following command:
node --version
This will output the current version of Node.js installed on your system, for example:
v14.17.3
In conclusion, Nodemon and Node.js are both essential tools for developing Node.js applications. Nodemon allows developers to focus on writing code without worrying about manually restarting the server, while Node.js provides a fast and efficient environment for building scalable network applications using JavaScript.
