Overview

The Initialize-Action GitHub Action is a powerful tool designed to simplify and optimize your Continuous Integration and Continuous Delivery (CI/CD) workflows. This action offers a range of features to enhance your development process:

• Cancel Previous Runs: The Initialize Action intelligently cancels any previous workflow runs if the current branch is not develop or main, preventing redundant executions and saving valuable time and resources.

• Dynamic Project Matrix Generation: Based on the detected changes in your repository, the Initialize Action dynamically generates a project matrix. This matrix is then used by subsequent jobs in your workflow, allowing for targeted and efficient execution of tasks.

• Custom Dependency Management: The action utilizes a unique dependency management system based on .depends files. These files, placed within each project directory, define the dependencies for that project. The Initialize Action analyzes these files to identify which projects are impacted by specific file changes.

How does it work?

The Initialize Action follows a clear process:

1. Cancel Previous Runs (if applicable).

2. Download and prepare the necessary scripts.

3. Identify modified files using the tj-actions/changed-files action.

4. Analyze the .depends files to determine affected projects.

5. Generate the dynamic project matrix for subsequent jobs.

Using the Initialize-Action is straightforward. In your workflow file, you include the action as a step, specifying parameters like the project root folder and the desired script version. The outputs from the Initialize-Action, such as the project matrix, can then be utilized by subsequent steps in your workflow.

Example Scenario

Let's imagine you have a mono-repository with multiple projects. A change is made to a shared component used by two of these projects. The Initialize Action would identify this change, analyze the dependencies defined in the .depends files, and automatically generate a project matrix containing only the two affected projects. Subsequent jobs in your workflow would then only be executed for those specific projects, resulting in a more focused and efficient build and deployment process.

Get Started

To start using the Initialize Action:

• Visit the public repository: robaone/initialize-action

• Explore the documentation in the README.md file.

• Review the provided examples to understand how to integrate the action into your workflow.

The Initialize-Action is a valuable asset for developers seeking to streamline their CI/CD pipelines and improve the efficiency of their workflows. With its intelligent features and easy-to-use implementation, it empowers you to focus on building and delivering high-quality software.
