Internationalization & Health Check Improvements

Overview

This PR implements i18n routes support, optimizes CloudFront caching configurations, adds advanced ElasticBeanstalk health check capabilities, and improves autoscaling performance.

Changes

Internationalization Support

• Added handling for localized routes in Next.js rendering and caching
• Now properly processes i18n routes with locale prefixes (e.g., /en-US/about) in cached routes configuration
• Ensures proper caching and routing for multi-language applications

CloudFront Distribution Optimizations

• Removed 'Cache-Control' from default forwarded headers list to improve cache hit ratio
• Prevents unnecessary cache invalidation from varying Cache-Control headers

ElasticBeanstalk Improvements

• Added custom health check path configuration:
  • Can now specify custom endpoint for health checks through healthCheckPath parameter
  • Default path is root (/) if not specified
• Improved logging capabilities:
  • Enabled CloudWatch log streaming for better visibility into application performance
  • Added IAM permissions for proper log streaming management
• Optimized auto-scaling settings:
  • Adjusted resource threshold triggers to improve cost efficiency
  • Modified upper threshold from 75% to 60% and lower threshold from 40% to 30% for earlier scaling actions

Infrastructure Quality of Life

• Added consistent deployment configuration options
• Parameter forwarding from deploy command to infrastructure stacks

Technical Details

• Modified i18n route regex generation to properly account for locale prefixes
• Added appropriate IAM permissions for CloudWatch logs integration
• Propagated health check path configuration through deployment chain

How to Use

The health check path can now be specified in deployment configuration:

// next-serverless.config.js
module.exports = {
  cache: {
    // cache settings
  },
  healthCheckPath: '/api/health' // Custom health check endpoint
}

Testing

• Tested with both i18n and non-i18n Next.js applications
• Verified proper functioning of health checks with custom paths
• Confirmed CloudWatch log streaming works correctly
