Lambda Region (Deprecated) ​

DEPRECATED

The lambdaRegion configuration option has been deprecated as of October 2025. This option is no longer necessary and will be ignored if provided.

What Changed? ​

Previously, users could manually select between eu-central-1 (Europe) and us-east-1 (USA) regions for Lambda function execution.

As of November 2025, the Topol Email Editor backend infrastructure now uses CloudFront CDN with automatic geographic routing. CloudFront intelligently routes requests to the nearest AWS region, providing:

  • Automatic optimization: No manual configuration needed
  • Lower latency: Requests are automatically routed to the closest edge location
  • Global coverage: Better performance worldwide without region selection

Migration Guide ​

If your code currently uses lambdaRegion:

ts
// Old code (no longer needed)
{
  lambdaStage: "production",
  lambdaRegion: "eu-central-1"  // This will be ignored
}

Simply remove the lambdaRegion option:

ts
// New code
{
  lambdaStage: "production";
}

Note: Existing code that includes lambdaRegion will continue to work without errors. The option is simply ignored. However, we recommend removing it from your configuration for cleaner code.
