Build nodejs in jenkins

With the continuous development of front-end technology, more and more websites and applications use JavaScript language as the development language. The modern JavaScript language can be used not only on the browser side, but also on the server side. Node.js is a server-side running environment based on JavaScript language. It is efficient, fast, lightweight, event-driven, etc., and is loved by the majority of developers. Jenkins is an open source automated build tool that can automatically build, deploy and test software, helping developers save time and energy. This article will introduce how to set up a Node.js environment in Jenkins.

1. Installing Jenkins

First, you need to install Jenkins on your server. You can download the Jenkins war package from the official website of Jenkins and install it, or you can install it through apt-get, yum and other commands.

After the installation is complete, you need to access the Jenkins web interface (usually http://localhost:8080), and then perform some basic configuration, such as creating an administrator account, installing necessary plug-ins, etc.

2. Install the Node.js plug-in

After the Jenkins installation is complete, you need to install the Node.js plug-in in Jenkins. This plug-in can help you perform Node.js related task.

In the Jenkins web interface, click "System Management" in the left navigation bar, and then select "Plug-in Management". Search for "Node.js" in "Optional Plugins", then check the "NodeJS Plugin" plug-in and click the "Install" button to install it.

After the installation is complete, you need to restart Jenkins for the plug-in to take effect. After restarting, two options, "Node.js Installation" and "Node.js Environment" will appear on the "System Management" page.

3. Install the Node.js environment

After installing the Node.js plug-in, you need to install the Node.js environment in Jenkins.

Select "Node.js Installation" on the "System Management" page, and then click the "Add Node.js" button. In the pop-up page, you need to fill in the Node.js version, installation directory and other information. The installation directory is generally "/usr/local/bin/node".

After clicking the "Save" button, you need to wait for a while for the Node.js environment to be installed.

4. Create Node.js job

After installing the Node.js environment, you can create a Node.js job in Jenkins.

In the Jenkins web interface, click "New Task" in the left navigation bar, and then select "Free Style Software Project". In the pop-up page, you need to fill in some basic information, such as project name, project description, etc.

In the "Build" tab, you can select build steps such as "Execute Shell" or "Execute Windows Batch Command". If you want to perform Node.js related tasks, you can use the "Node.js command" build step.

In the "Node.js command" build step, you need to fill in some Node.js-related information, such as Node.js version, npm command, build script, etc.

After saving all configurations, you can click the "Save" button and then run the job.

5. Summary

Through the above steps, you can set up a Node.js environment in Jenkins and create a Node.js job. In actual projects, you can use this job together with other build steps to realize automated build, testing, deployment and other functions to improve development efficiency and quality.
