Like many others, we’re using Jenkins at Caphyon for tasks like testing or deploying some of our projects. These days I had to figure out a way to have a different Node.js version on a Jenkins project bound to a branch I was working on.
What is Jenkins?
Jenkins is a self-contained, open source automation server which can be used to automate all sorts of tasks related to building, testing, and delivering or deploying software.
from the docs
So I had a branch I was working on and needed a different Node.js version for that, mostly for trying out things, without risking to change any other Jenkins project configuration.
Specifically, I had a branch with some tests based on Jest and Puppeteer that rely on
async/await which is available from Node.js 7.6. Whilst the Node.js version installed on the Jenkins machine was lower than that, I was needing a newer Node.js for my Jenkins project that my branch was bound to.
The solution I found was to install the Jenkins NodeJS Plugin which was already having some of the features and functionality I was looking for.
The Jenkins project with a given Node.js 8.0 version.
So, what Jenkins NodeJS Plugin does:
It allows creating as many Node.js installations “profiles” as you want. Let’s say you could have some installations to play with like legacy 6x, 8x or latest stable Node.js.
It auto installs the given version of Node.js, on every Jenkins project where it will be needed.
It allows to install globally some npm packages inside each Node.js installation and these npm packages will be made available to the PATH: those could be Gulp, Webpack or you name it.
It allows executing Node.js scripts, under the given Node.js installation.
That’s pretty much it, hope you find this useful!
