Demo Install Dependencies

Demo: Install Node.js Dependencies in Your Jenkins Pipeline

In this tutorial, we’ll show you how to integrate a Node.js install step into your Jenkins Pipeline, verify your Node.js version, and install project dependencies. By the end, you’ll see how Blue Ocean displays your pipeline stages and where the node_modules folder appears in the workspace.

Prerequisites

Pipeline Configuration

1. Open your Jenkinsfile.
2. Configure the Node.js tool and define two stages:
   • VM Node Version: Verifies node and npm versions.
   • Installing Dependencies: Runs npm install --no-audit.

pipeline {
    agent any

    tools {
        nodejs 'nodejs-22-6-0'
    }

    stages {
        stage('VM Node Version') {
            steps {
                sh 'node -v'
                sh 'npm -v'
            }
        }

        stage('Installing Dependencies') {
            steps {
                sh 'npm install --no-audit'
            }
        }
    }
}

Run the Pipeline

1. Commit and push your Jenkinsfile changes.
2. In Blue Ocean, watch the pipeline execute both stages in sequence.

Sample Output for “Installing Dependencies”

+ npm install --no-audit
added 365 packages in 5s
44 packages are looking for funding
run 'npm fund' for details

Verify the Workspace

After the build completes, navigate to Workspaces in the Jenkins UI. You should see a node_modules directory with all installed dependencies:
