From e7b5cfa1c9166f66f47cf6e08dd01a0de3263e39 Mon Sep 17 00:00:00 2001 From: Gunther Brunner Date: Fri, 27 Jun 2025 07:20:16 +0900 Subject: [PATCH 1/9] feat(server): add comprehensive Zod v4 integration MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This PR introduces a new Zod v4 integration module that runs in parallel with the existing v3 implementation, allowing for gradual migration. Key features: - 🚀 Performance improvements (14x faster string parsing, 7x faster arrays) - 📝 Enhanced string validation with dedicated format validators - 🔢 Precise number types (int8, uint32, float64, etc.) - 🏷️ Native metadata support and JSON Schema generation - 📁 File validation support for actions - 🔧 Enhanced custom functions with v4 optimizations - 📚 Comprehensive documentation and migration guide The implementation includes: - zodV4.ts: Core implementation with all v4 features - zodV4.test.ts: Comprehensive test suite - zodV4.example.ts: Real-world usage examples - zodV4.README.md: Documentation and migration guide - Updated package.json exports This is a non-breaking change that adds new functionality alongside the existing v3 support. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude --- packages/convex-helpers/package.json | 8 + .../convex-helpers/server/zodV4.README.md | 264 ++++ .../convex-helpers/server/zodV4.example.ts | 426 +++++++ packages/convex-helpers/server/zodV4.test.ts | 546 ++++++++ packages/convex-helpers/server/zodV4.ts | 1135 +++++++++++++++++ 5 files changed, 2379 insertions(+) create mode 100644 packages/convex-helpers/server/zodV4.README.md create mode 100644 packages/convex-helpers/server/zodV4.example.ts create mode 100644 packages/convex-helpers/server/zodV4.test.ts create mode 100644 packages/convex-helpers/server/zodV4.ts diff --git a/packages/convex-helpers/package.json b/packages/convex-helpers/package.json index 739d9d85..f156045f 100644 --- a/packages/convex-helpers/package.json +++ b/packages/convex-helpers/package.json @@ -115,6 +115,14 @@ "types": "./server/zod.d.ts", "default": "./server/zod.js" }, + "./server/zodV4.example": { + "types": "./server/zodV4.example.d.ts", + "default": "./server/zodV4.example.js" + }, + "./server/zodV4": { + "types": "./server/zodV4.d.ts", + "default": "./server/zodV4.js" + }, "./react/*": { "types": "./react/*.d.ts", "default": "./react/*.js" diff --git a/packages/convex-helpers/server/zodV4.README.md b/packages/convex-helpers/server/zodV4.README.md new file mode 100644 index 00000000..e23a5aa7 --- /dev/null +++ b/packages/convex-helpers/server/zodV4.README.md @@ -0,0 +1,264 @@ +# Zod v4 Integration for Convex + +This module provides enhanced Zod v4 integration with Convex, featuring all the latest improvements and new capabilities introduced in Zod v4. + +## Installation + +```bash +npm install convex-helpers zod@latest +``` + +## Key Features + +### 🚀 Performance Improvements +- 14x faster string parsing +- 7x faster array parsing +- 6.5x faster object parsing +- 100x reduction in TypeScript type instantiations +- 2x reduction in core bundle size + +### 📝 Enhanced String Validation + +```typescript +import { stringFormats } from "convex-helpers/server/zodV4";
