Know Everything About Node Package Manager In Drupal

The open-source software library Node Package Manager (NPM) has more than 800,000 code files. NPM is a command-line tool that installs, updates, or removes the node.js packages of a program.



Run the npm install command right away inside the theme folder of the project. All of the packages in the package.json file will be installed.

Once that’s done, type the following command into the command line to check if NPM was installed correctly. This will tell you what version of NPM you are using.

npm -v

If you have an older version of NPM, you can bring it up to date with this command:

npm install npm -g

There are two ways to use NPM: Global mode and Local mode.

Global mode: It does things that affect all Node.js programs on the machine.

Local mode: It does things for a specific local directory that only affect applications in that directory.

How to add a dependency to package.json

All the information about an NPM package is in a single file called package.json. The information in package.json must be in JSON format. The two areas in that file that must be filled in are “name” and “version.”

The main goal is to automate managing dependencies and packages. In the package.json file, you can list all the dependencies of your project or program here.


Here, “test” is the name of the Project and “1.0.0” is the version number.

The “test” project needs Bootstrap, Gulp, and Gulp-Sass, along with the versions of those packages.

Run the following command in the shell to install the node modules inside the theme folder for your project.  

npm install

When you run this script, all of the modules that depend on it will be installed.

dependency modules

Inside the node_modules folder, you will find the modules that are loaded based on the other modules.



Gulp is used to run tasks. It has a lot of uses. It runs front-end tasks for big web applications by using JavaScript code. It also makes jobs like CSS preprocessing, HTML minification, adding library files together, compiling SASS files, and more happen automatically. Here, we use Gulp to change.scss files to.css files.

Inside the gulpfile.js file, we’ll tell Gulp what jobs it can do


When using non-Drupal features, we must import the CSS or JS files for that module as a library in the theme_name.libraries.yml file. Next, we need to call the library for that twig file in order to see the changes that need to be made. 

Using this tool, we can add other NPM packages to your project, such as slick-carousel, responsive tabs, etc.

npm install <package name>

Update the packages with this command:

C:\MyNodeProj> npm update <package name>

To uninstall the package, use this command:

C:\>npm uninstall <package name>

Developers can use Node Package Manager to automate a lot of front-end chores. It lets you install and play with a huge number of third-party libraries, which can help you run jobs that are hard or take a long time. In this short guide, we talked about how to set up NPM and how to use Gulp with Drupal.

In conclusion, it is important for current web development projects to know how to use the Node Package Manager (NPM) in Drupal. NPM adds a lot of JavaScript libraries, tools, and dependencies to Drupal. This lets workers streamline their workflows, improve front-end development, and make dynamic and interactive web experiences.

By using NPM within the Drupal ecosystem, developers can use the large JavaScript ecosystem to make sure their websites stay up-to-date, efficient, and easy to manage. With NPM integration, Drupal developers can build websites that meet the needs of the dynamic web world of today. This includes managing dependencies and improving the performance of the front end.

As Drupal continues to change and adapt to the constantly changing digital world, using NPM in your Drupal projects is a forward-thinking way to improve your development processes and give your users great experiences.
