Puts Debuggerer
Ruby library for improved puts debugging, automatically displaying bonus useful information such as source line number and source code.
To get started, visit the preview environments example repository and fork it into your account.
The actual workflow steps are fairly simple. First, it installs the Koyeb CLI using the koyeb-community/install-koyeb-cli action. You may notice that this step references a secret called KOYEB_API_TOKEN. You will have to configure this for your fork later on.
The second step builds and deploys the pull request branch on Koyeb using the koyeb/action-git-deploy action. The pull request branch name can be found in the github.head_ref context object. We use this to specify the branch to deploy and to name the Koyeb App and Service. The remaining lines configure the port and routing that the application expects.
In this tutorial, we will explain how to automatically deploy your application using GitHub Actions each time a pull request is made for your GitHub repository.
A GitHub account to host your repositories configure the pull request preview integration.
To demonstrate how to set up preview environments for a GitHub repository, we'll work with an example repository containing a basic Node.js web app built with Express. The application responds to requests with a simple "hello world" message.
