The article provides a comprehensive guide on using artifacts within GitHub Actions, a tool for automating software development workflows on GitHub. It elaborates on how artifacts, which are byproducts of build processes like executable binaries or test results, can be used to enhance workflows by allowing for the storage and transfer of data between different workflow runs. The tutorial walks through setting up a basic Node.js continuous integration workflow that uses GitHub Actions to upload and download artifacts, demonstrating how to create release packages from build outputs. Key steps include configuring actions such as actions/upload-artifact@v3 and actions/download-artifact@v3 to manage artifacts, ensuring their accessibility across workflow executions. The guide emphasizes the importance of artifacts for tasks like generating deployment packages, sharing test reports, and storing logs for diagnostics. Additionally, the article highlights Earthly's capabilities to improve build times within GitHub Actions, offering tools to streamline and enhance the development process further.
