This tutorial provides a detailed guide on using GitHub Actions to automate the process of building, testing, and deploying a Vue.js application to Netlify. It begins by explaining the creation of a basic to-do app with Vue.js, including setting up unit tests using vue-test-utils. The tutorial then details how to connect the app to a GitHub repository and discusses disabling Netlify's default autodeploy feature to instead use GitHub Actions for controlled deployment after successful tests. Key steps include configuring secret keys in GitHub for Netlify deployment, setting up GitHub Actions workflows for automatic deployment on pushes to the master branch, and creating another workflow for automatically merging pull requests when tests pass. The tutorial also covers creating and configuring secret tokens and labels necessary for automating these processes with GitHub and Netlify, providing a comprehensive overview for developers looking to streamline their deployment pipeline.
