Pipeline Status: develop staging main

PipeCraft is a powerful CLI tool for automating trunk-based development workflows with GitHub Actions. It generates intelligent CI/CD pipelines that adapt to your codebase structure, support multiple domains (monorepos), handle semantic versioning, and manage branch flows with fast-forward merging strategies.

Table of Contents

Features

  • Automatic CI/CD Pipeline Generation - Generate GitHub Actions workflows tailored to your branch flow
  • Pre-Flight Checks - Validates prerequisites before generating workflows with helpful error messages
  • Domain-Based Change Detection - Smart path-based detection for monorepo architectures
  • Semantic Versioning - Automatic version bumping based on conventional commits
  • Branch Flow Management - Support for custom branch flows (develop → staging → main)
  • Fast-Forward Merging - Automatic branch management with configurable merge strategies
  • Idempotent Regeneration - Only regenerate when configuration or templates change
  • User Job Preservation - Regenerates pipelines while preserving your custom jobs and comments
  • Customizable Actions - Define actions per branch merge (tests, deploys, version bumps)
  • GitHub Setup Automation - Automated token and repository setup validation

Note: This release focuses on GitHub Actions workflows. GitLab CI/CD support is planned for a future release. Currently, the ciProvider field accepts 'gitlab' but generates GitHub Actions syntax.

Prerequisites

  • Git - Version control system
  • GitHub Account - For GitHub Actions workflows
  • Node.js 18.0.0 or higher - For npm installation

Quick Start

  1. Initialize PipeCraft in your project:

    npx pipecraft init
  2. Generate your CI/CD workflows:

    npx pipecraft generate
  3. Commit the generated files:

    git add .github/workflows .pipecraftrc.json
    git commit -m "chore: add PipeCraft workflows"
    git push

That's it! Your trunk-based development workflow is now automated.

Installation

No installation required! Just run commands with npx:

npx pipecraft init

Option 2: Global installation via npm

npm install -g pipecraft

Option 3: Local project installation

npm install --save-dev pipecraft

Then add to your package.json scripts:

{
"scripts": {
"workflow:init": "pipecraft init",
"workflow:generate": "pipecraft generate",
"workflow:validate": "pipecraft validate"
}
}

Usage

CLI Examples

PipeCraft provides several commands to manage your trunk-based development workflows:

1. Initialize Configuration

Create a basic configuration with default settings:

pipecraft init

Force overwrite existing configuration:

pipecraft init --force

Note: The init command currently generates a default configuration file with standard trunk flow settings (develop → staging → main). You can then edit the .pipecraftrc.json file to customize branch names, domains, and other settings.

2. Generate Workflows

Generate CI/CD workflows based on your configuration:

pipecraft generate

The generate command automatically runs pre-flight checks to validate:

  • Configuration file exists and is valid
  • Required fields are present (ciProvider, branchFlow, domains)
  • Current directory is a git repository
  • Git remote is configured
  • .github/workflows directory is writable

If any check fails, you'll see helpful error messages with suggestions. Example output:

🔍 Running pre-flight checks...

✅ Configuration found: /path/to/.pipecraftrc.json
✅ Configuration is valid
❌ Not in a git repository
💡 Initialize git: 'git init' or clone an existing repository

Output verbosity levels:

Normal mode (default) - Clean, actionable output:

pipecraft generate

Shows only essential information: pre-flight checks and completion status.

Verbose mode - Shows file operations:

pipecraft generate --verbose

Includes file merge status, config paths, and workflow generation details.

Debug mode - Full internal details:

pipecraft generate --debug

Includes everything from verbose mode plus internal debugging information like branch flow context, job ordering, and template operations.

Other options:

Skip pre-flight checks (not recommended):

pipecraft generate --skip-checks

Force regeneration (bypass cache):

pipecraft generate --force

Preview what would be generated (dry run):

pipecraft generate --dry-run

Use custom config and output paths:

pipecraft generate --config custom-config.json --output-pipeline .github/workflows/custom.yml

3. Validate Configuration

Check if your configuration is valid:

pipecraft validate

Validate a custom config file:

pipecraft validate --config custom-config.json

4. Verify Setup

Verify that PipeCraft is properly configured:

pipecraft verify

This checks:

  • Configuration file exists and is valid
  • GitHub Actions workflows exist (for GitHub projects)
  • Repository structure is correct

5. Version Management

Check current and next version:

pipecraft version --check

Bump version based on conventional commits:

pipecraft version --bump

Create a release:

pipecraft version --release

6. Branch Setup

Create all branches defined in your branch flow:

pipecraft setup

This automatically creates and pushes all branches to your remote repository.

Configuration

PipeCraft uses cosmiconfig for flexible configuration discovery. It will look for configuration in the following order:

  1. Command-line options
  2. .pipecraftrc.json file
  3. .pipecraftrc file
  4. pipecraft key in package.json
  5. Default values

Example .pipecraftrc.json:

{
"ciProvider": "github",
"mergeStrategy": "fast-forward",
"requireConventionalCommits": true,
"initialBranch": "develop",
"finalBranch": "main",
"branchFlow": ["develop", "staging", "main"],
"semver": {
"bumpRules": {
"feat": "minor",
"fix": "patch",
"breaking": "major"
}
},
"domains": {
"api": {
"paths": ["apps/api/**"],
"description": "API application changes"
},
"web": {
"paths": ["apps/web/**"],
"description": "Web application changes"
}
}
}

Pre-Flight Checks

PipeCraft includes comprehensive pre-flight validation to catch common errors before generating workflows. This helps new users avoid frustration and ensures your project is properly configured.

What Gets Checked

When you run pipecraft generate, the following checks are automatically performed:

  1. Configuration File Discovery

    • Searches for config using cosmiconfig
    • Looks in: .pipecraftrc.json, .pipecraftrc, package.json (pipecraft key)
    • Searches parent directories recursively
    • Shows the exact path where config was found
  2. Configuration Validation

    • Verifies JSON syntax is valid
    • Checks all required fields are present:
      • ciProvider (github or gitlab)
      • branchFlow (array of branch names)
      • domains (at least one domain configured)
    • Validates domain configuration has paths defined
  3. Git Repository Check

    • Verifies current directory is a git repository
    • Suggests running git init if not
  4. Git Remote Check

    • Verifies git remote is configured
    • Shows the remote URL
    • Suggests adding a remote if missing
  5. Write Permissions

    • Tests that .github/workflows directory can be created/written to
    • Checks file system permissions

Example Pre-Flight Output

All checks passing:

🔍 Running pre-flight checks...

✅ Configuration found: /path/to/project/.pipecraftrc.json
✅ Configuration is valid
✅ Current directory is a git repository
✅ Git remote configured: https://github.com/user/repo.git
✅ .github/workflows directory is writable

✅ All pre-flight checks passed!

Checks failing with helpful suggestions:

🔍 Running pre-flight checks...

❌ No PipeCraft configuration found
💡 Run 'pipecraft init' to create a configuration file

❌ Not in a git repository
💡 Initialize git: 'git init' or clone an existing repository

❌ No git remote configured
💡 Add a remote: 'git remote add origin <url>'

❌ Pre-flight checks failed. Fix the issues above and try again.
Or use --skip-checks to bypass (not recommended)

Skipping Pre-Flight Checks

While not recommended, you can skip pre-flight checks if needed:

pipecraft generate --skip-checks

When you might skip checks:

  • CI/CD environment with non-standard setup
  • Using PipeCraft in a script/automation
  • Advanced users who know the risks

Why you shouldn't skip:

  • Prevents cryptic errors during generation
  • Saves time by catching issues early
  • Provides actionable error messages
  • Ensures consistent behavior across environments

GitHub Actions Setup

PipeCraft requires specific GitHub Actions permissions and repository settings to function correctly. The setup-github command helps you configure everything automatically.

What Gets Configured

The setup-github command configures:

  1. Workflow Permissions

    • Default workflow permissions: write (for creating tags and pushing changes)
    • Can create/approve pull requests: Yes (for automated PR creation)
  2. Repository Auto-Merge

    • Enables auto-merge feature at repository level
    • Required for automatic promotion between branches
  3. Branch Protection Rules (for branches with auto-merge enabled)

    • Status checks enabled (no specific checks required)
    • Required linear history (prevents messy merges)
    • No force pushes or branch deletion
    • These rules are required for GitHub's auto-merge feature to work

Usage

Interactive Mode (Default)

Prompts you for each permission change:

pipecraft setup-github

The command will:

  1. Check your current repository permissions
  2. Enable repository-level auto-merge if needed
  3. Configure branch protection for branches with autoMerge: true in config
  4. Prompt you to apply each change
  5. Update the settings if you accept

Auto-Apply Mode

Automatically applies all required changes without prompting:

pipecraft setup-github --apply
# or
pipecraft setup-github --force

This mode is useful for:

  • CI/CD pipeline setup scripts
  • Automated repository initialization
  • Batch configuration of multiple repositories

Example Output

Interactive mode:

🔍 Checking GitHub repository configuration...

📦 Repository: user/repo
✅ GitHub token found
🔍 Fetching current workflow permissions...

📋 Current GitHub Actions Workflow Permissions:
Default permissions: read
Can create/approve PRs: No

⚠️ PipeCraft requires the following permissions:
• Default permissions: write (for creating tags and pushing)
• Can create/approve PRs: Yes (for automated PR creation)

? Change default workflow permissions from "read" to "write"? (Y/n) Yes

🔍 Checking auto-merge configuration...
✅ Enabled auto-merge for repository
📋 Branches with auto-merge enabled: staging
? Enable branch protection for 'staging' to support auto-merge? (Y/n) Yes
🔧 Configuring branch protection for staging...

Auto-apply mode:

🔍 Checking GitHub repository configuration...

📦 Repository: user/repo
✅ GitHub token found
🔍 Fetching current workflow permissions...

✅ Workflow permissions are already configured correctly!

🔍 Checking auto-merge configuration...
✅ Enabled auto-merge for repository
📋 Branches with auto-merge enabled: staging
🔧 Configuring branch protection for staging...
✅ Branch protection enabled for staging

✨ Setup complete!

💡 You can verify the changes at:
https://github.com/user/repo/settings/actions

Authentication

The command requires a GitHub token with admin access to your repository. It will automatically use:

  1. GITHUB_TOKEN environment variable
  2. GH_TOKEN environment variable
  3. GitHub CLI (gh) authentication

To authenticate with GitHub CLI:

gh auth login

Or set an environment variable:

export GITHUB_TOKEN=ghp_your_token_here

Manual Configuration

You can also configure these settings manually:

Workflow Permissions:

  1. Go to your repository on GitHub
  2. Navigate to SettingsActionsGeneral
  3. Under "Workflow permissions":
    • Select Read and write permissions
    • Check Allow GitHub Actions to create and approve pull requests
  4. Click Save

Repository Auto-Merge:

  1. Navigate to SettingsGeneral
  2. Scroll to "Pull Requests"
  3. Check Allow auto-merge
  4. Click Save

Branch Protection (for branches with auto-merge):

  1. Navigate to SettingsBranches
  2. Click Add branch protection rule or edit existing rule
  3. In "Branch name pattern", enter the branch name (e.g., staging)
  4. Configure the following:
    • Check Require status checks to pass before merging
    • Leave status checks empty (or add your own)
    • Check Require linear history
    • Leave other options as needed
  5. Click Create or Save changes

Note: Branch protection rules are required for auto-merge to work in GitHub.

Domains (Monorepo Support)

Define multiple domains for path-based change detection:

{
"domains": {
"api": {
"paths": ["apps/api/**", "libs/api-utils/**"],
"description": "API application and utilities"
},
"web": {
"paths": ["apps/web/**", "libs/ui-components/**"],
"description": "Web application and UI components"
},
"mobile": {
"paths": ["apps/mobile/**"],
"description": "Mobile application"
}
}
}

Each domain can have:

  • paths (required): Array of glob patterns for file matching
  • description (optional): Human-readable description

Versioning Configuration

{
"versioning": {
"enabled": true,
"releaseItConfig": ".release-it.cjs",
"conventionalCommits": true,
"autoTag": true,
"autoPush": true,
"changelog": true,
"bumpRules": {
"feat": "minor",
"fix": "patch",
"breaking": "major"
}
}
}

Rebuild/Idempotency Configuration

Control when workflows are regenerated:

{
"rebuild": {
"enabled": true,
"skipIfUnchanged": true,
"forceRegenerate": false,
"watchMode": false,
"hashAlgorithm": "sha256",
"cacheFile": ".pipecraft-cache.json",
"ignorePatterns": ["*.md", "docs/**"]
}
}

Domain-Based Workflows

PipeCraft excels at managing monorepo workflows with multiple domains. The generated workflows automatically detect which domains have changes and run appropriate jobs.

How It Works

  1. Change Detection: The changes job uses GitHub's paths-filter action to detect which domains have modifications
  2. Conditional Jobs: Domain-specific jobs only run if changes are detected in their paths
  3. Parallel Execution: Independent domains run in parallel for faster CI times
  4. Dependency Management: Jobs can depend on specific domain changes

Example Generated Workflow

name: Pipeline

on:
pull_request:
branches:
- develop
- staging
- main

jobs:
changes:
runs-on: ubuntu-latest
outputs:
api: ${{ steps.changes.outputs.api }}
web: ${{ steps.changes.outputs.web }}
steps:
- uses: actions/checkout@v4
- uses: dorny/paths-filter@v3
id: changes
with:
filters: |
api:
- 'apps/api/**'
web:
- 'apps/web/**'

test-api:
needs: changes
if: needs.changes.outputs.api == 'true'
runs-on: ubuntu-latest
steps:
- uses: actions/checkout@v4
- name: Run API tests
run: npm test --workspace=api

test-web:
needs: changes
if: needs.changes.outputs.web == 'true'
runs-on: ubuntu-latest
steps:
- uses: actions/checkout@v4
- name: Run Web tests
run: npm test --workspace=web

Version Management

PipeCraft integrates with release-it for automated semantic versioning.

Setup Version Management

pipecraft init --with-versioning

This creates:

  • .release-it.cjs - Release-it configuration
  • commitlint.config.js - Commit message linting
  • .husky/commit-msg - Git hook for commit validation

Version Commands

Check what the next version would be:

pipecraft version --check

Output:

📦 Current version: 1.2.3
📦 Next version: 1.3.0 (minor)
📝 Conventional commits: ✅ Valid

Bump version based on commits:

pipecraft version --bump

Create a full release:

pipecraft version --release

Conventional Commits

PipeCraft works best with conventional commits:

  • feat: - New feature (minor bump)
  • fix: - Bug fix (patch bump)
  • feat!: or BREAKING CHANGE: - Breaking change (major bump)
  • chore:, docs:, style:, refactor:, test: - No version bump

Example:

git commit -m "feat: add user authentication"  # Bumps to 1.3.0
git commit -m "fix: resolve login bug" # Bumps to 1.3.1
git commit -m "feat!: redesign API structure" # Bumps to 2.0.0

Troubleshooting

Common Issues

1. Workflows Not Generating

Problem: Running pipecraft generate doesn't create files.

Solutions:

  • PipeCraft now runs automatic pre-flight checks that will catch most issues
  • Review the pre-flight check output for specific problems
  • Check if configuration is valid: pipecraft validate
  • Use --force to bypass cache: pipecraft generate --force
  • Use --verbose for detailed output: pipecraft generate --verbose
  • Use --debug for full debugging output: pipecraft generate --debug
  • Verify file permissions in .github/workflows/

2. Configuration Validation Errors

Problem: Getting validation errors when running commands.

Solutions:

  • Ensure all required fields are present (ciProvider, branchFlow, domains)
  • Check that initialBranch and finalBranch are in branchFlow
  • Verify domain paths are valid glob patterns
  • Use pipecraft validate to see specific errors

3. Branch Flow Not Working

Problem: Branches aren't being created or fast-forwarded.

Solutions:

  • Run pipecraft setup to create missing branches
  • Verify GitHub token has push permissions
  • Check that branch protection rules allow fast-forward merges
  • Ensure branches exist on remote: git push origin branch-name

4. Version Management Not Working

Problem: Version bumps aren't happening automatically.

Solutions:
