Access Jenkins Credentials Environment Variables from Node.js - node.js

Question

I have set up some credentials environment variables using the Credentials plugin for Jenkins.
I am using them in my Jenkinsfile like this :
pipeline {
agent any
environment {
DEV_GOOGLE_CLIENT_ID = credentials('DEV_GOOGLE_CLIENT_ID')
DEV_GOOGLE_CLIENT_SECRET = credentials('DEV_GOOGLE_CLIENT_SECRET')
}
stages {
stage('Install dependencies') {
steps {
dir("./codes") {
sh 'npm install'
}
}
}
stage('Stop previous forever process') {
steps {
dir("./codes") {
sh 'forever stop dev || ls'
}
}
}
stage('Clean forever logs') {
steps {
dir("./codes") {
sh 'forever cleanlogs'
}
}
}
stage('Test ') {
steps {
dir("./codes") {
sh 'npm run test'
}
}
}
}
}
In my Node.js code, I'm trying to get access to those env variables by writing process.env.DEV_GOOGLE_CLIENT_SECRET but that is not working I am getting undefined ...
Thank you

Answer 1

Which type of credentials did you use: secret text or username and password?
While using username and password you can get username and password separately each other like this
pipeline {
agent any
environment {
DEV_GOOGLE_CLIENT = credentials('DEV_GOOGLE_CLIENT')
}
stages {
stage('Get username and password') {
steps {
echo "username is $DEV_GOOGLE_CLIENT_USR"
echo "password is $DEV_GOOGLE_CLIENT_PSW"
}
}
}
I don't know how to call $DEV_GOOGLE_CLIENT_USR and $DEV_GOOGLE_CLIENT_PSW in node.js, sorry.

You pass your credentials in this order: 1 Jenkins credentials > 2 pipeline environment variable > 2 node.js command line parameter > 3 node.js environment variable
1 Jenkins credentials
Make sure to create a Jenkins credentials as secret text first: https://www.jenkins.io/doc/book/using/using-credentials/
2 pipeline environment variable + node.js command line parameter
pipeline {
agent any
environment {
JENKINS_SECRET_TEXT=credentials('JENKINS_SECRET_TEXT')
}
stages {
stage('Pass secret as command line parameter') {
steps {
sh 'SECRET_ENV_VAR="$JENKINS_SECRET_TEXT" node app.js'
}
}
}
}
3 node.js
console.log("SECRET_ENV_VAR:", process.env.SECRET_ENV_VAR);
