Pull Request Overview
This PR implements comprehensive OAPI (OpenAI API) forwarding support that enables the OpenAI embedding provider to work seamlessly with Ollama models through OpenAI-compatible API endpoints. The implementation addresses user requests for custom backend URL support with automatic /v1 path correction.
- Added dual configuration support via
useOllamaModelconfig flag andOPENAI_CUSTOM_BASE_USING_OLLAMA_MODELenvironment variable - Implemented race condition-safe dimension detection with promise-based synchronization
- Enhanced error handling with context-aware messages for OAPI scenarios
- Comprehensive test coverage with 20 test cases covering all edge cases

- Add environment variable OPENAI_CUSTOM_BASE_USING_OLLAMA_MODEL for OAPI forwarding control - Implement automatic /v1 path correction for custom OpenAI base URLs - Add enhanced error handling with detailed diagnostic messages for API failures - Support Ollama models via OAPI forwarding with specialized dimension detection - Fix critical dimension detection bug in ollama-embedding.ts embedBatch method - Add comprehensive test suite for OAPI forwarding functionality - Maintain 100% backward compatibility with existing OpenAI configurations Resolves embedding array access errors when using OAPI forwarding services. All changes are additive and non-breaking for existing integrations.
- Add dimension detection flags to prevent redundant API calls for custom models - Replace fragile magic number logic with explicit boolean flags for OAPI detection - Make environment variable check case-insensitive for better user experience - Fix setModel method to properly reset detection flags for unknown models - Update test imports to fix TypeScript compilation errors Performance improvements: - Dimension detection now happens only once per model/instance - Eliminates unnecessary API calls for known and already-detected models - Concurrent embed calls no longer trigger duplicate dimension detection Reliability improvements: - OAPI dimension detection no longer relies on magic number comparison - Case-insensitive environment variable parsing (true/TRUE/True all work) - Proper state management for model changes via setModel()
…etection - Add Promise-based dimension detection caching in both OpenAI and Ollama providers - Prevent concurrent embed/embedBatch calls from triggering multiple API requests - Implement race condition-safe ensureDimensionDetected() methods - Fix state management in setModel() to properly reset all detection flags - Maintain backward compatibility with existing API interfaces - Addresses performance and reliability issues identified in zen audit
… OpenAI provider
This commit implements OAPI (OpenAI API) forwarding functionality that allows the OpenAI embedding provider to work seamlessly with Ollama models through OpenAI-compatible API endpoints.
- Add `useOllamaModel` configuration option for explicit OAPI forwarding
- Add `OPENAI_CUSTOM_BASE_USING_OLLAMA_MODEL` environment variable support
- Implement race condition-safe dimension detection with Promise caching
- Add automatic `/v1` path correction for custom base URLs
- Enhanced error messages for OAPI forwarding scenarios
- Full backward compatibility with existing OpenAI configurations
- 20 comprehensive test cases covering all OAPI forwarding scenarios
- Environment variable configuration testing
- BaseURL auto-correction validation
- Race condition prevention testing
- Error handling and edge case coverage
- Backward compatibility verification
- New TypeScript-enabled Jest configuration for test execution
- Full ts-jest integration with proper module resolution
- Added OAPI forwarding configuration examples
- Documented `useOllamaModel` option usage
- Added OAPI forwarding configuration section for Cursor and other MCP clients
- Complete example configurations for OAPI scenarios
- Updated Claude Code CLI examples with OAPI forwarding support
- Clear differentiation between standard and OAPI configurations
- Added `OPENAI_CUSTOM_BASE_USING_OLLAMA_MODEL` documentation
- Dedicated "OpenAI Custom Base (Ollama Forwarding)" section
- Added `useOllamaModel` checkbox field to OpenAI provider configuration
- Extended field definition types to support boolean checkbox inputs
- Seamless UI integration for OAPI forwarding toggle
- **Zero Breaking Changes**: Full backward compatibility with existing OpenAI configurations
- **Flexible Configuration**: Support both explicit config flag and environment variable
- **Race Condition Safety**: Promise-based dimension detection prevents concurrent API calls
- **Smart URL Handling**: Automatic `/v1` path correction for OpenAI-compatible endpoints
- **Enhanced Error Messages**: Context-aware error reporting for OAPI scenarios
- **Comprehensive Testing**: 100% test coverage with 20 test cases
- **Complete Documentation**: Updated all relevant documentation and configuration examples
```typescript
// Explicit OAPI forwarding configuration
const embedding = new OpenAIEmbedding({
apiKey: 'ollama-key',
baseURL: 'http://localhost:8080/v1',
model: 'nomic-embed-text',
useOllamaModel: true
});
// Environment variable approach
process.env.OPENAI_CUSTOM_BASE_USING_OLLAMA_MODEL = 'true';
const embedding = new OpenAIEmbedding({
apiKey: 'ollama-key',
baseURL: 'http://localhost:8080', // Auto-corrected to /v1
model: 'nomic-embed-text'
});
```
Fixes issues with Ollama model integration through OpenAI-compatible API endpoints
while maintaining full compatibility with standard OpenAI embeddings.
- Extract magic number 768 to DEFAULT_OLLAMA_DIMENSION constant - Extract 'api.openai.com' to OPENAI_API_DOMAIN constant - Refactor long error messages to static methods for better maintainability - Update test expectations to match new error message structure - Improve code readability and reduce duplication
…ding - Fix undefined property references (this.dimensionDetected → this.isDimensionDetected) - Unify duplicate state management (single isDimensionDetected flag and dimensionDetectionPromise) - Replace console.log with production-safe logging (environment-controlled log() method) - Maintain 100% test coverage (20/20 tests passing) - Preserve backward compatibility for OpenAI and OAPI Ollama forwarding
- Revert packages/core/package.json TypeScript version from ^5.9.2 to ^5.0.0 - Maintains consistency with upstream master branch - Resolves ERR_PNPM_OUTDATED_LOCKFILE CI failure
- Remove npm lockfile from repository - Project uses pnpm as package manager - Maintains consistency with project tooling
