== @himanoa/npm-workspace-based-gha-workflow-optimizer

@himanoa/npm-workspace-based-gha-workflow-optimizer is a tool designed to optimize the execution of GitHub Actions workflows based on the npm workspace configuration.

It analyzes the workspace definitions in package.json and automatically generates paths filters for workflow definitions using package names as prefixes.

This ensures that workflows are only triggered by relevant changes.

=== Features

• Workflow Optimization: Executes workflows based on changes to related packages, as defined in the package.json workspace configuration.
• Automated paths Filter Generation: Automatically generates paths filters for workflow definitions using package names as prefixes, preventing unnecessary workflow executions.
• Automated dependenciy analysis: Analyzes the dependencies between packages and builds a paths filter based on the analysis results.

=== Prerequisites

• Node.js
• npm
• A GitHub repository with GitHub Actions set up

=== Installation

Install the package using npm:

[source,sh]

npm install @himanoa/npm-workspace-based-gha-workflow-optimizer --save-dev

=== Usage

Running this tool analyzes the workspace definitions in package.json and automatically updates the paths filters in GitHub Actions workflow files based on changes to related workspaces. This ensures that workflows are triggered only by changes to specific packages.

==== Before Use

Example of a GitHub Actions workflow file before using the tool. This workflow is triggered by any push or pull request event:

Filename is a-format.yaml [source,yaml]

name: format on: [push, pull_request]

jobs: format: runs-on: ubuntu-latest steps: - uses: actions/checkout@v4 - uses: actions/setup-node@v4 with: node-version: '18.x' registry-url: 'https://registry.npmjs.org' - uses: pnpm/action-setup@v2 with: version: 8 - run: pnpm install - run: pnpm format

==== After Use

After running the tool, the workflow file is automatically updated to trigger the workflow only for changes related to workspace a, as defined in package.json:

[source,yaml]

name: format on: push: paths: - 'workspaces/a/' pull_request: paths: - 'workspaces/a/'

jobs: format: runs-on: ubuntu-latest steps: - uses: actions/checkout@v4 - uses: actions/setup-node@v4 with: node-version: '18.x' registry-url: 'https://registry.npmjs.org' - uses: pnpm/action-setup@v2 with: version: 8 - run: pnpm install - run: pnpm format

This change helps avoid unnecessary workflow executions, saving resources and optimizing the CI/CD process.

==== How to Run

To run the tool, use the following command:

[source,sh]

npx @himanoa/npm-workspace-based-gha-workflow-optimizer optimize

The tool will automatically analyze the relevant workflow files and update the paths filters as necessary.
