January 7, 10 min read With GitHub Actions, you can easily integrate this into your GitHub project without using an external platform. Continuous integration CI is the software engineering practice that requires frequent commits to a shared repository. To understand this better, let us consider the opposite of CI.

Before CI, people would work on feature branches for weeks or months and then try to merge this branch to a main branch. Think about all that could go wrong during such merge — merge conflicts and failing tests, just to mention a few. Continuous integration tries to prevent all of these by encouraging small and frequent code updates. 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.

The only difference is that in continuous delivery, human intervention e. However, in continuous deployment, everything happens automatically. For the rest of this post, we refer to CD as continuous deployment. Before we jump into the code, let us get a brief overview of GitHub Actions. You can create workflows that build and test every pull request to your repository, or deploy merged pull requests to production. You can decide to run tests for every pull request PR created or merged, you can automatically deploy merged PR, and you can even set up a workflow to add the appropriate labels when a PR is created.

Click on the Configure button for the Simple workflow. You will see this page. Let us try to understand what is going on here. Take note of the directory in which the file is created:. A workflow is a configurable automated process that runs one or more jobs. You can see the workflow file created here is a YAML file. A workflow is defined by a YAML file in your. The file created contains the code below. We will use this to explain other components of GitHub Actions, the workflow being one component:.

This snippet from the sample workflow indicates that the workflow will be run whenever a push or pull request is made to the main branch. A workflow can also be scheduled to run at certain times, like a cron job. You can read about it here. A job is a set of steps that a workflow should execute on the same runner. This could either be a shell script or an action. Steps are executed in order in the same runner and are dependent on each other. This is good because data can be shared from one step to another.

Jobs are run in parallel, but you can also configure a job to depend on another job. For instance, you may want to deploy a merged PR only when the build succeeds or tests have passed. Runners This indicates the server the job should run on. An action performs a complex, repetitive task. It is a custom application for the GitHub Actions platform. Actions are really important to reduce the amount of code you need to set up a workflow.

You can either write an action or use an already existing action from the GitHub Marketplace. For our application, we will need to use a Node. We will get back to this later. For now, rename the file to a name of your choice. Commit this workflow click on the Start commit button , then merge and clone our repository into our local machine. To see GitHub Actions at work, let us create a very simple Node application in the project we just cloned. If you want to add GitHub Actions to an existing project, you may skip this part.

We will be using Express for our application and Jest and SuperTest for testing the application:. Next, we add index. In your terminal, run the following commands:.

In the app. In the package. Run npm start and npm test to ensure that everything works as expected. Let us get back to our GitHub workflow we pulled from our repository: the main.

We will modify this file to build the application and run tests whenever a pull request is merged to the main branch, and deploy this application to Heroku.

Since we are building a Node application, we need an action to set up Node. We do not need to build this from scratch since this action is already available in the GitHub Marketplace. So we go to GitHub Marketplace to find an action we can use. On GitHub, click on Marketplace in the top navigation. Search for Node and you see a Setup Node. Click on it to see a description of the action and how to use it.

You will see this screen with a description. At this point, if we push this to our main branch, we will see this action run.

But because we want to go a step further to add automatic deployment to Heroku, we will add a second job to our workflow. Once again, we do not need to build the action for this deployment from scratch. The GitHub Marketplace saves the day. So we will go back to the marketplace and search for Deploy to Heroku. You can decide to use an action of your choice for this depending on your needs. If you run your app in a Docker container, you may want to use the ones for Docker.

We will copy the sample code there in the build part, add it to the jobs, and modify it to suit our needs. So, add this to the main. Since we already have a build job, we will rename this job to deploy. Also, we need this job to run only when the tests run successfully, so to prevent it from running in parallel to the build job, we will add that it depends on the build.

Now notice that for this job to run, we need a Heroku account. If you do not have an account, you can sign up here. Click on the image on the top right part of the navigation to get to your account settings. For our workflow to have access to this key, we need to add it to the Secrets of our repository. After that, to ensure that our Heroku app name is unique and to prevent our deployment from failing, we can create a new app on Heroku.

On your dashboard, click on New and follow the steps to create the app. Copy the app name and update the workflow with your created app name and your Heroku email address. We are ready to test our workflow now. To ensure that everything is in place, here is what the main. Since this is a YAML file, ensure that it is spaced correctly:. You can see from the image above that the build was successful and the deployment is ongoing.

Also notice that the deploy job ran only after the build job completed. If all goes well, you will get a successful deployment like the one below. You can create multiple workflows for the needs of your repository. For instance, if you work on a repository with many contributors, you can decide to create a workflow that runs when a pull request to the main branch is created, and another that runs when the pull request is merged.

One good thing about GitHub Actions is that you do not have to build all the actions needed for your workflows from scratch. The marketplace already has a lot of actions you can use or customize to suit your needs. You can also build custom actions that are specific to the needs of your organization. Thanks for reading and I really hope this tutorial serves as a good guide to get started with GitHub Actions. For further reading, you can reference the official documentation on GitHub Actions.

CI/CD for JavaScript

By default when a new Buffalo application is generated via the buffalo new command, a Webpack configuration file is generated, and the application is set up to use Webpack as the asset pipeline for the application. If npm is not found on the machine generating the new Buffalo application, then Webpack will not be configured and the asset pipeline would be skipped. The asset pipeline can also be skipped during application generation with the --skip-webpack flag. None of the installed packages are required, and may be removed. They are included for convenience.

You can deploy your Node. This guide explains how to use GitHub Actions to build, test, and deploy a Node. This will let you stop storing these credentials as long-lived secrets and provide other security benefits. Before creating your GitHub Actions workflow, you will first need to complete the following setup steps:. Generate your Azure deployment credentials using a publish profile. For more information, see " Generate deployment credentials " in the Azure documentation. For more information on creating secrets, see " Encrypted secrets. Optionally, configure a deployment environment. Environments are used to describe a general deployment target like production , staging , or development.
