From 7e16bdadc6bb52c1c64e0a507a954918744f6b32 Mon Sep 17 00:00:00 2001 From: Matt Apperson Date: Thu, 30 Oct 2025 15:39:51 -0400 Subject: [PATCH 1/7] feat: Add memory system for conversation history management Implements a comprehensive memory system for the OpenRouter TypeScript SDK that enables: - Thread-based conversation management - Resource (user) management - Working memory (both thread and resource scoped) - Auto-injection of conversation history - Auto-saving of messages - Serialization/hydration for persistence - In-memory storage implementation (with interface for future storage backends) ## Key Features ### Core Components - **Memory**: Main API class for managing threads, resources, and working memory - **MemoryStorage**: Interface for storage implementations - **InMemoryStorage**: Default in-memory storage implementation - **Types**: Comprehensive type definitions for all memory entities ### Auto-Features - **Auto-inject**: Automatically prepends conversation history to API requests - **Auto-save**: Automatically saves messages after responses complete - **Configurable**: Max history messages, enable/disable auto features ### Usage ```typescript import { OpenRouter, Memory, InMemoryStorage } from "@openrouter/sdk"; const memory = new Memory(new InMemoryStorage()); const client = new OpenRouter({ apiKey, memory }); const response = client.getResponse({ model: "meta-llama/llama-3.2-1b-instruct", input: [{ role: "user", content: "Hello!" }], threadId: "thread-123", resourceId: "user-456" }); const text = await response.text; // History auto-injected, message auto-saved ``` ### Testing - Comprehensive E2E tests covering all memory features - All tests passing - Usage example included in examples/memory-usage.ts ### Architecture - Non-breaking: Memory is completely optional - Compatible with generated Speakeasy code - Modular: Easy to add new storage backends - Type-safe: Full TypeScript support --- examples/memory-usage.ts | 143 +++++++++++ src/funcs/getResponse.ts | 38 ++- src/index.ts | 15 ++ src/lib/memory/index.ts | 25 ++ src/lib/memory/memory.ts | 363 ++++++++++++++++++++++++++++ src/lib/memory/storage/in-memory.ts | 245 +++++++++++++++++++ src/lib/memory/storage/interface.ts | 148 ++++++++++++ src/lib/memory/types.ts | 150 ++++++++++++ src/lib/response-wrapper.ts | 128 +++++++++- src/sdk/sdk.ts | 31 ++- tests/e2e/memory.test.ts | 183 ++++++++++++++ 11 files changed, 1459 insertions(+), 10 deletions(-) create mode 100644 examples/memory-usage.ts create mode 100644 src/lib/memory/index.ts create mode 100644 src/lib/memory/memory.ts create mode 100644 src/lib/memory/storage/in-memory.ts create mode 100644 src/lib/memory/storage/interface.ts create mode 100644 src/lib/memory/types.ts create mode 100644 tests/e2e/memory.test.ts diff --git a/examples/memory-usage.ts b/examples/memory-usage.ts new file mode 100644 index 00000000..42656f2e --- /dev/null +++ b/examples/memory-usage.ts @@ -0,0 +1,143 @@ +/** + * Memory System Usage Example + * + * This example demonstrates how to use the memory system in the OpenRouter SDK + * to maintain conversation history across multiple API calls. + */ + +import { OpenRouter, Memory, InMemoryStorage } from "@openrouter/sdk";

This refactoring: - Moves serialize/hydrate methods from Memory class to MemoryStorage interface - Implements serialize/hydrate/serializeThread/hydrateThread in InMemoryStorage - Updates tests to use storage.serialize() instead of memory.serialize() - Updates usage example to show proper storage serialization pattern This makes the architecture cleaner and allows different storage backends to implement their own serialization strategies (e.g., direct DB export, file formats, etc.) --- examples/memory-usage.ts | 61 +++++++-------------------- src/lib/memory/memory.ts | 65 ----------------------------- src/lib/memory/storage/in-memory.ts | 39 ++++++++++++++++- src/lib/memory/storage/interface.ts | 25 ++++++++--- tests/e2e/memory.test.ts | 29 ++++++++----- 5 files changed, 91 insertions(+), 128 deletions(-) diff --git a/examples/memory-usage.ts b/examples/memory-usage.ts index 42656f2e..b56517a8 100644 --- a/examples/memory-usage.ts +++ b/examples/memory-usage.ts @@ -8,8 +8,11 @@ import { OpenRouter, Memory, InMemoryStorage } from "@openrouter/sdk";

From 6905221f147bd863088276bbe319d0c61c88e88f Mon Sep 17 00:00:00 2001 From: Matt Apperson Date: Thu, 30 Oct 2025 18:30:17 -0400 Subject: [PATCH 3/7] feat: Add context-aware memory enhancements Adds provider-agnostic enhancements to memory system to support advanced features like token budgeting, message editing, caching, and priority-based selection. ## New Features ### Enhanced Message Metadata (Optional) - status: 'active' | 'archived' | 'deleted' for filtering - importance: 0-1 score for priority-based selection - tokenCount: Provider-calculated token count - cacheControl: Cache configuration with expiry - version: Message versioning for edit tracking - editedFrom: Original message ID for edit history ### Context Window Management - ContextWindowConfig: maxTokens, strategy, retainRecentMessages - Strategies: fifo, priority-based, token-aware - Token budget-aware message retrieval ### New Storage Methods (Optional) - updateMessage: Edit existing messages - getMessageHistory: Get message version history - getThreadTokenCount: Calculate total tokens - getMessagesByTokenBudget: Retrieve within token limit - getCachedMessages: Get messages with active cache - invalidateCache: Expire cached messages - getMessagesByStatus: Filter by status - getMessagesByImportance: Filter by importance score ### Memory Class Enhancements - updateMessage: Edit messages with versioning - getMessageVersions: Get edit history - getThreadTokenCount: Get token usage - getMessagesWithinBudget: Token-aware retrieval - getCachedMessages: Cache-aware retrieval - invalidateCache: Cache management - getMessagesByStatus: Status filtering - getMessagesByImportance: Priority filtering ## Design Principles - Backward compatible: All new fields/methods are optional - Provider agnostic: No specific API dependencies - Graceful degradation: Falls back when storage doesn't support features - Type safe: Full TypeScript support with proper types ## Implementation - All optional methods implemented in InMemoryStorage - Memory class checks for method availability before calling - New types exported: CacheControl, ContextWindowConfig - All existing tests pass (10/10) --- src/index.ts | 14 +-- src/lib/memory/index.ts | 2 + src/lib/memory/memory.ts | 157 +++++++++++++++++++++++++++- src/lib/memory/storage/in-memory.ts | 137 ++++++++++++++++++++++++ src/lib/memory/storage/interface.ts | 82 +++++++++++++++ src/lib/memory/types.ts | 53 ++++++++++ 6 files changed, 437 insertions(+), 8 deletions(-) diff --git a/src/index.ts b/src/index.ts index f4ac5f57..4641819f 100644 --- a/src/index.ts +++ b/src/index.ts @@ -13,17 +13,19 @@ export { ReusableReadableStream } from "./lib/reusable-stream.js";
