Serverless Plugin Manager

Common utilities and patterns for serverless plugin CI/CD pipelines. This library abstracts common testing, deployment, and cleanup patterns to make serverless plugin development more consistent and reliable.

🚀 Features

• 🧪 Comprehensive Testing: Package validation, feature testing, and integration testing
• 🧹 Finally-like Cleanup: Automatic cleanup that runs even when processes fail
• ☁️ AWS Resource Management: Automatic AWS resource cleanup and validation
• 📊 Consistent Logging: Beautiful, structured logging with emojis and colors
• 🔧 CLI Tools: Ready-to-use CLI commands for common operations
• 📋 Script Templates: Pre-built script templates for quick setup

📦 Installation

npm install @hyperdrive.bot/serverless-plugin-manager

🏗️ Quick Start

Using CLI Tools

# Run package validation tests
npx @hyperdrive.bot/serverless-plugin-manager test package-validation --plugin your-plugin-name

# Run feature tests  
npx @hyperdrive.bot/serverless-plugin-manager test feature-tests --plugin your-plugin-name

# Run integration tests
npx @hyperdrive.bot/serverless-plugin-manager test integration-tests --plugin your-plugin-name

# Run all tests
npx @hyperdrive.bot/serverless-plugin-manager test all --plugin your-plugin-name

# Clean up resources
npx @hyperdrive.bot/serverless-plugin-manager cleanup all --stage test

Using Script Templates

Copy script templates to your project:

cp node_modules/@hyperdrive.bot/serverless-plugin-manager/templates/*.sh ./scripts/
chmod +x ./scripts/*.sh

Then use in package.json:

{
  "scripts": {
    "test:package-validation": "./scripts/package-validation-script.sh",
    "test:features": "./scripts/feature-tests-script.sh", 
    "test:integration": "./scripts/integration-tests-script.sh",
    "cleanup": "./scripts/cleanup-script.sh"
  }
}

Using Programmatically

import { 
  TestManager, 
  createDefaultTestConfig,
  getCleanupManager,
  logger 
} from '@hyperdrive.bot/serverless-plugin-manager'

// Set up automatic cleanup
const cleanupManager = getCleanupManager()
cleanupManager.trackDirectory('./test-project')
cleanupManager.addAwsPattern({ 
  type: 'stack', 
  pattern: '*test*', 
  region: 'us-east-1' 
})

// Run tests
const config = createDefaultTestConfig('your-plugin-name')
const testManager = new TestManager(config)

const result = await testManager.runAllTests()
if (result.success) {
  logger.success('All tests passed!')
} else {
  logger.error('Tests failed')
  process.exit(1)
}

// Cleanup happens automatically on process exit

🧪 Test Management

Package Validation

• Tests regular serverless packaging
• Tests module-specific packaging
• Validates generated artifacts
• Tests print functionality
• Validates module isolation

Feature Testing

• Tests all plugin features
• Tests custom transformers
• Tests all supported categories
• Tests edge cases and error conditions
• Validates complex module structures

Integration Testing

• Deploys actual AWS resources
• Tests against live deployments
• Validates API endpoints
• Tests post-deployment operations
• Ensures proper resource cleanup

🧹 Cleanup Management

Automatic Cleanup

The cleanup manager provides "finally"-like behavior:

import { getCleanupManager, trackResource, trackFile } from '@hyperdrive.bot/serverless-plugin-manager'

// Track resources for cleanup
trackResource({ type: 'stack', identifier: 'my-test-stack', region: 'us-east-1' })
trackFile('./temporary-file.txt')

// Cleanup happens automatically on:
// - Normal process exit
// - SIGINT (Ctrl+C)  
// - SIGTERM
// - Uncaught exceptions
// - Unhandled promise rejections

AWS Resource Cleanup

• CloudFormation stacks
• Lambda functions
• DynamoDB tables
• SQS queues
• S3 buckets (empties before deletion)
• API Gateway APIs
• Step Functions

Pattern-based Cleanup

Clean up resources by naming patterns:

cleanupManager.addAwsPattern({
  type: 'stack',
  pattern: '*test*',
  region: 'us-east-1'
})

📊 Logging

Structured Logging

import { logger } from '@hyperdrive.bot/serverless-plugin-manager'

logger.step('Starting deployment')
logger.info('Information message')
logger.success('Operation completed')
logger.error('Something failed')
logger.aws('deploy', 'my-stack', 'us-east-1')
logger.cleanup('delete', 'test-resource')

Progress Tracking

logger.progress(3, 10, 'Processing modules...')
logger.section('Test Results')
logger.testResults('My Test', true, 'Test passed', 1500)

⚙️ Configuration

Default Configuration

const config = createDefaultTestConfig('your-plugin-name')
// Automatically sets up test modules, stages, and AWS regions

Custom Configuration

const config: PluginConfig = {
  pluginName: 'your-plugin-name',
  testProjectName: 'test-project',
  deploymentStage: 'dev',
  serverlessVersion: '4',
  awsRegion: 'us-east-1',
  testModules: [
    {
      name: 'auth',
      categories: [
        {
          name: 'functions',
          files: [
            {
              fileName: 'login.yml',
              type: 'yaml',
              content: '...'
            }
          ]
        }
      ],
      expectedFunctions: ['login']
