Development Guide

Prerequisites

• Node.js: >= 16.0.0

• Git: For version control
• OpenProject Instance: For testing (can be local or cloud)

Initial Setup

1. Clone the repository:

   git clone https://gitlab.com/somitcoop/projects/coopflow/n8n-nodes-openproject.git
   cd n8n-nodes-openproject
   

2. Install dependencies:

   npm install
   

3. Verify installation:

   npm run lint
   

Development Workflow

Building the Node

# Development build with watch mode
npm run dev

# Production build
npm run build

# Clean build (remove dist folder first)
rm -rf dist && npm run build

Code Quality

# Run linter
npm run lint

# Fix linting issues automatically
npm run lintfix

# Format code with Prettier
npm run format

Testing Locally

1. Build the node:

   npm run build
   

2. Install in local n8n:

   # Create custom nodes directory
   mkdir -p ~/.n8n/custom/nodes/n8n-nodes-openproject
   
   # Copy built files
   cp -r dist/* ~/.n8n/custom/nodes/n8n-nodes-openproject/
   cp package.json ~/.n8n/custom/nodes/n8n-nodes-openproject/
   

3. Restart n8n:

   # If using n8n locally
   n8n start
   
   # If using Docker
   docker restart n8n
   

4. Test in n8n:

   • Open n8n in your browser
   • Add the OpenProject node to a workflow
   • Configure credentials
   • Test different operations

Testing with Example Workflow

1. Import the example workflow:

   • Open n8n
   • Go to Workflows
   • Click "Import from file"
   • Select src/nodes/OpenProject/example.json

2. Configure credentials:

   • Add your OpenProject API credentials
   • Update the workflow parameters as needed

3. Run the workflow:

   • Activate the workflow
   • Monitor the execution
   • Check the results

Publishing Guide

Prerequisites for Publishing

1. npm Account: Create an account at https://www.npmjs.com/signup
2. Unique Package Name: Ensure n8n-nodes-openproject is available
3. Git Repository: All changes committed and pushed

Publishing Process

1. Prepare for Publishing

# Ensure all changes are committed
git add .
git commit -m "Prepare for publishing v1.0.0"
git push origin main

# Verify build works
npm run build

# Check package contents
npm pack --dry-run

2. Login to npm

# Check if already logged in
npm whoami

# If not logged in, login
npm login
# Enter your username, password, and email

3. Publish the Package

# Publish to npm
npm publish

# For scoped packages (if needed)
npm publish --access public

4. Verify Publication

# Check if package is published
npm view n8n-nodes-openproject

# Install and test the published package
npm install n8n-nodes-openproject

Version Management

Updating Versions

# Patch version (bug fixes)
npm version patch

# Minor version (new features)
npm version minor

# Major version (breaking changes)
npm version major

Publishing Updates

# After version bump
git add .
git commit -m "Release v1.0.1"
git push origin main
git push --tags

# Publish new version
npm publish

Troubleshooting Publishing

Common Issues

1. Package name already taken:

   # Check availability
   npm view n8n-nodes-openproject
   
   # If taken, update package.json with new name
   # Example: n8n-nodes-openproject-custom
   

2. Authentication issues:

   # Re-login to npm
   npm logout
   npm login
   

3. Build errors:

   # Clean and rebuild
   rm -rf dist node_modules package-lock.json
   npm install
   npm run build
