Greptile Overview

Summary

This PR implements two key improvements: fixes to the TypeScript SDK publishing pipeline and database connection optimizations for better performance. The changes modernize the ts-sdk package by transitioning it from CommonJS to ES modules, which involves updating the TypeScript configuration, package.json module type, and Vitest configuration to properly handle module resolution. The database performance improvements reduce connection pool sizes across multiple services - the main database pool is reduced from 30 to 20 connections, the socket server's pool from 15 to 5 connections, and the socket manager's pool maintains 3 connections with adjusted timeouts.

The ts-sdk changes align the entire build pipeline with ES module standards, fixing module resolution issues that were likely preventing successful SDK publishing. The publishing workflow is updated to install dependencies from the repository root rather than the package directory, supporting monorepo workspace management. For database optimizations, the changes implement a coordinated reduction in maximum connections across services while fine-tuning timeout configurations - increasing idle timeouts to 20 seconds (allowing connections to stay pooled longer) while reducing connect timeouts to 10 seconds (failing faster on connection issues). These changes work together to reduce overall database connection pressure while maintaining responsive real-time operations for the socket server components.

Confidence score: 4/5

• This PR is generally safe to merge with some potential breaking changes in the ts-sdk package
• Score reflects solid database optimizations but concerns about ES module transition compatibility
• Pay close attention to ts-sdk package.json exports configuration which may not work correctly with dual format support after ES module transition

1. .github/workflows/publish-ts-sdk.yml, line 82 (link)

   syntax: GitHub repository URL appears incorrect - should be 'simstudioai/sim' not 'simstudio/sim' based on the repository context

2. packages/ts-sdk/package.json, line 13 (link)

   logic: Both import and require point to the same file. After adding "type": "module", CommonJS consumers may not be able to require this file. Consider building separate CommonJS and ESM bundles or using a tool like tsup for dual format publishing.
