GitHub Actions Workflow

The workflow auto-publishes on every push to master:

name: Publish to npm
on:
  push:
    branches: [master]
  workflow_dispatch:

jobs:
  publish:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4
      - uses: actions/setup-node@v4
        with:
          node-version: '20'
          registry-url: 'https://registry.npmjs.org'
      - run: npm publish --access public
        env:
          NODE_AUTH_TOKEN: ${{ secrets.NPM_TOKEN }}

Local Development Workflow

Option 1: Auto-Publish (Recommended)

# Make changes to dist/nodes/ExecuteCommandPlus/ExecuteCommandPlus.node.js
# Then commit and push

git add -A
git commit -m "Your message"
git push origin master

# GitHub Actions automatically:
# 1. Detects push to master
# 2. Runs workflow
# 3. Publishes to npm
# Takes ~30 seconds

Option 2: Manual Publish

# Update version in package.json
npm version patch  # or minor, major

# Publish directly
npm publish --access public

Option 3: Local Testing

# Test the package locally before publishing
cd /tmp
mkdir test-pkg
cd test-pkg
npm init -y
npm install /path/to/n8n-nodes-forgiving-cli-1.0.0.tgz

# Verify it loads correctly
node -e "
const pkg = require('./node_modules/n8n-nodes-forgiving-cli/dist/nodes/ExecuteCommandPlus/ExecuteCommandPlus.node.js');
const Node = pkg.ExecuteCommandPlus;
const node = new Node();
console.log('✅ Loaded:', node.description.name);
