What are GitHub Actions?Īccording to the GitHub documentation on GitHub Actions, “GitHub Actions is a continuous integration and continuous delivery (CI/CD) platform that allows you to automate your build, test, and deployment pipeline.

Before we jump into the code, let us get a brief overview of GitHub Actions. Now, let’s consider how we can use GitHub Actions to configure a CI/CD pipeline for a Node.js project.

Better code quality is ensured because you can configure the pipeline to test against linting rules.

This makes it easier to prevent changes that may break these flows in production

A major part of the CI/CD pipeline is the automated testing of critical flows for a project.

Since CI/CD encourages small, frequent changes, code review time is shorter.

This makes it easier to fix or roll back changes if necessary Since changes are smaller, it is easier to isolate the changes that cause a bug after deployment.

Fault isolation is simpler and faster.

Here are more advantages in addition to those already mentioned above: For the rest of this post, we refer to CD as continuous deployment. However, in continuous deployment, everything happens automatically. The only difference is that in continuous delivery, human intervention (e.g., the click of a button) is needed for the changes to be released. This is often interchanged with continuous delivery and that’s because they are very similar. What is continuous deployment?Ĭontinuous deployment means code changes are automatically deployed/released to a testing or production environment as soon as they are merged. When a code is committed to a repository, it can be built and tested against setup workflows to ensure that the code does not introduce any errors. Think about all that could go wrong during such merge - merge conflicts and failing tests, just to mention a few.Ĭontinuous integration tries to prevent all of these by encouraging small and frequent code updates. Before CI, people would work on feature branches for weeks or months and then try to merge this branch to a main branch. To understand this better, let us consider the opposite of CI. You may have gotten so used to this practice that you may wonder why there’s a term for it.

What is continuous integration?Ĭontinuous integration (CI) is the software engineering practice that requires frequent commits to a shared repository. Jest and Heroku will be used, but it’s not compulsory to follow alongīefore we delve into GitHub Actions for CI/CD, let’s understand what continuous integration and what continuous deployment is.To use this tutorial, you will need the following: In this tutorial, we see how you can use GitHub Actions to set up a CI/CD pipeline to your project. With GitHub Actions, you can easily integrate this into your GitHub project without using an external platform. CI/CD in Node.js with GitHub ActionsĬontinuous integration/continuous deployment is a software engineering practice that helps teams to collaborate better and improve their overall software.
