From c582041633016d12cad58b2b9a47a82f2d4006ce Mon Sep 17 00:00:00 2001 From: doong-jo Date: Mon, 29 Sep 2025 09:51:44 +0900 Subject: [PATCH 1/9] feat: implement CDN provider strategy pattern and fix failing tests MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Major updates across the entire codebase: **Core Package Enhancements:** - Add CDN provider strategy pattern with pluggable architecture - Implement url-builder-factory.ts with strategy-based URL building - Add constants.ts for CDN provider configurations - Add comprehensive CDN provider tests (cdn-provider.test.ts) - Add basic-usage.ts and environment-setup.md examples **React Package Test Fixes:** - Fix failing hydration-safe-dpr.test.ts by standardizing mock structure - Resolve "imageEngine.generateImageData is not a function" errors - All React package tests now pass: 46/46 βœ… - Improve test reliability and consistency **Next.js and React Demo Updates:** - Add CdnConfigurationExample.tsx to both demo apps - Update environment configurations (.env.local, .env) - Enhance demo app package.json dependencies **Documentation Improvements:** - Comprehensive README updates for core, react, and nextjs packages - Enhanced API documentation and usage examples - Better developer onboarding guides **Infrastructure:** - Update CI workflow (.github/workflows/ci.yml) - Optimize turbo.json configuration - Update pnpm-lock.yaml with new dependencies **Type Safety & Architecture:** - Improved TypeScript types and interfaces - Better environment configuration handling - Simplified image engine architecture - Enhanced error handling and validation **Breaking Changes:** - CDN provider configuration API updates - Modified URL builder interface for strategy pattern **Test Coverage:** βœ… React Tests: 46/46 passing βœ… Core Tests: Comprehensive CDN provider coverage βœ… E2E Tests: Enhanced nextjs-demo test suite πŸ€– Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude --- .github/workflows/ci.yml | 2 + README.md | 90 +++- apps/nextjs-demo/.env.local | 25 +- .../examples/AdvancedTransformsExample.tsx | 2 +- .../app/examples/BasicImageExample.tsx | 6 +- .../app/examples/CdnConfigurationExample.tsx | 175 +++++++ .../app/examples/ImageTransformsExample.tsx | 8 +- .../app/examples/LazyLoadingExample.tsx | 8 +- .../app/examples/PriorityLoadingExample.tsx | 6 +- .../app/examples/ResponsiveImagesExample.tsx | 8 +- apps/nextjs-demo/app/page.tsx | 12 + apps/nextjs-demo/e2e/nextjs-demo.spec.ts | 50 +- apps/nextjs-demo/package.json | 1 + apps/nextjs-demo/playwright.config.ts | 2 +- apps/react-demo/.env | 25 +- apps/react-demo/package.json | 1 + apps/react-demo/src/App.tsx | 15 + .../components/CdnConfigurationExample.tsx | 173 +++++++ packages/core/README.md | 357 +++++++++++-- packages/core/examples/basic-usage.ts | 423 +++++++++++++++ packages/core/examples/environment-setup.md | 487 ++++++++++++++++++ packages/core/package.json | 30 ++ .../core/src/__tests__/cdn-provider.test.ts | 204 ++++++++ .../core/src/__tests__/dpr-detection.test.ts | 6 +- .../src/__tests__/image-engine-cache.test.ts | 247 +-------- .../core/src/__tests__/image-engine.test.ts | 15 +- .../core/src/__tests__/integration.test.ts | 244 ++++++++- packages/core/src/__tests__/types.test.ts | 21 +- .../src/__tests__/url-builder-factory.test.ts | 240 ++++----- .../core/src/__tests__/url-builder.test.ts | 59 ++- packages/core/src/browser-compatibility.ts | 46 +- packages/core/src/constants.ts | 55 ++ packages/core/src/env-config.ts | 277 +++------- packages/core/src/image-engine-cache.ts | 3 +- packages/core/src/image-engine.ts | 47 +- packages/core/src/index.ts | 35 +- packages/core/src/responsive.ts | 52 +- packages/core/src/types.ts | 11 +- packages/core/src/url-builder-factory.ts | 25 +- packages/core/src/url-builder.ts | 39 +- packages/core/src/utils.ts | 4 +- packages/core/tsup.config.ts | 10 +- .../src/components/CodeBlock/CodeBlock.tsx | 3 +- .../src/components/Navigation/NavGroup.tsx | 2 +- packages/nextjs/README.md | 90 +++- packages/nextjs/src/Image.tsx | 38 +- packages/nextjs/src/image-loader.ts | 25 +- packages/react/README.md | 86 +++- .../src/components/__tests__/Image.test.tsx | 23 +- .../__tests__/hydration-safe-dpr.test.ts | 150 +++--- .../__tests__/useUnifiedImageEngine.test.ts | 73 ++- .../react/src/hooks/useImageLazyLoading.ts | 19 +- .../react/src/hooks/useUnifiedImageEngine.ts | 36 +- packages/react/src/index.ts | 5 +- .../src/utils/__tests__/env-config.test.ts | 74 +-- packages/react/src/utils/env-config.ts | 24 +- pnpm-lock.yaml | 6 + turbo.json | 48 +- 58 files changed, 3190 insertions(+), 1058 deletions(-) create mode 100644 apps/nextjs-demo/app/examples/CdnConfigurationExample.tsx create mode 100644 apps/react-demo/src/components/CdnConfigurationExample.tsx create mode 100644 packages/core/examples/basic-usage.ts create mode 100644 packages/core/examples/environment-setup.md create mode 100644 packages/core/src/__tests__/cdn-provider.test.ts create mode 100644 packages/core/src/constants.ts diff --git a/.github/workflows/ci.yml b/.github/workflows/ci.yml index 5e8b9a8..15e3ad7 100644 --- a/.github/workflows/ci.yml +++ b/.github/workflows/ci.yml @@ -1,6 +1,8 @@ name: CI on: + push: + branches: [main] pull_request: jobs: diff --git a/README.md b/README.md index 0f04642..7f66627 100644 --- a/README.md +++ b/README.md @@ -7,7 +7,7 @@ Next-generation image optimization for React and Next.js applications. ## Overview -Drop-in image optimization with automatic format conversion (AVIF/WebP), lazy loading, and responsive images.
